This contribution presents a two-step hybrid diagnostic approach, combining k-means clustering for subset formation, followed by subset analysis conducted by human experts. As the feature input vector has a significant influence on the performance of unsupervised machine learning algorithms, seven feature input vectors derived from traditional methods, including Duval pentagon method, Rogers ratio method, three ratios technique, Denkyoken method, ensemble gas characteristics method, Duval triangle method, and Gouda triangle method were explored for the subset formation stage. The seven proposed individual methods, corresponding to the seven feature input vectors, were implemented using a dataset of 595 DGA samples and tested on an additional 254 DGA samples. Furthermore, a combined technique based on a support vector machine was introduced, utilising the diagnostic results of the individual methods as input features. From training and testing, with diagnostic outcomes of 91.09% and 90.94%, the combined technique demonstrated the highest overall diagnostic accuracies. Using the IEC TC10 database, the diagnosis accuracies of the proposed diagnostic methods were compared to existing methods of literature. From the results obtained, the combined technique outperformed the proposed individual methods and existing methods used for comparison.

本文提出了一种两步混合诊断方法,结合了用于形成子集的 k-means 聚类,以及由人类专家进行的子集分析。由于特征输入向量对无监督机器学习算法的性能有重要影响,因此在子集形成阶段探讨了从传统方法中衍生出的七个特征输入向量,包括杜瓦尔五边形法、罗杰斯比率法、三比率技术、Denkyoken 法、集合气体特征法、杜瓦尔三角形法和高达三角形法。使用 595 个 DGA 样本数据集实现了与七个特征输入向量相对应的七种拟议的单独方法,并在另外 254 个 DGA 样本上进行了测试。此外,还引入了一种基于支持向量机的组合技术,利用单个方法的诊断结果作为输入特征。通过训练和测试,综合技术的诊断结果分别为 91.09% 和 90.94%,总体诊断准确率最高。利用 IEC TC10 数据库,将所提出的诊断方法的诊断准确率与现有的文献方法进行了比较。从获得的结果来看,组合技术优于所建议的单个方法和用于比较的现有方法。

This research investigated the influence of temperature and humidity on the giant dielectric (GD) properties of 1% indium tin oxide and 1% Ta2O5 co‐doped TiO2 ceramics sintered at different temperatures. A single phase of rutile TiO2 was obtained in all sintered samples. The mean grain size increased with higher sintering temperatures, resulting in ceramics with a relative density exceeding 98%. A uniform dispersion of dopants and major elements was achieved. Remarkably, the dielectric constant increased significantly from 2 × 103 to 3.7 × 104 with a rising sintering temperature, primarily due to the enlarged grain size. Concurrently, the authors observed low loss tangents, ranging from tanδ≈0.016 to 0.024 at 1 kHz. Slight variations in the dielectric constant were observed with temperature from room temperature up to 210°C, while maintaining remarkably low tanδ. The GD properties were attributed to space charge polarisation at internal interfaces and defect dipoles. Further research explored the impact of environmental conditions on dielectric properties. Remarkably, the ceramics exhibited minimal capacitance variations of less than 10% within the relative humidity range of 30%–95% and temperatures from 15 to 85°C, indicating excellent dielectric stability.
本研究调查了温度和湿度对在不同温度下烧结的 1%氧化铟锡和 1%Ta2O5共掺杂二氧化钛陶瓷的巨介电常数(GD)特性的影响。在所有烧结样品中都得到了单相金红石型二氧化钛。平均晶粒尺寸随着烧结温度的升高而增大,从而使陶瓷的相对密度超过 98%。掺杂剂和主要元素实现了均匀分散。值得注意的是,随着烧结温度的升高,介电常数从 2 × 103 显著增加到 3.7 × 104,这主要是由于晶粒尺寸增大所致。与此同时,作者还观察到了较低的损耗正切,在 1 kHz 时,损耗正切从 tanδ≈0.016 到 0.024 不等。介电常数随温度(从室温到 210°C)的变化而略有变化,但 tanδ 却保持在很低的水平。GD 特性归因于内部界面的空间电荷极化和缺陷偶极子。进一步的研究探索了环境条件对介电特性的影响。值得注意的是,在相对湿度为 30%-95% 和温度为 15-85°C 的范围内,陶瓷的电容变化极小,小于 10%,这表明陶瓷具有出色的介电性能稳定性。

The authors present an innovative photonic crystal fibre (PCF) detector that has the ability to detect sulphur dioxide (SO2) gas. This deadly gas having no tone at all with a strong aroma. Our suggested sensor is designed with heptagonal cladding along with octagonal core. It displays exclusive performance in detecting SO2 with an elevated relative sensitivity (RS). The max RS for this sensor is 87.39% with a tiny Confinement Loss of 6.8194 × 10−4 dB/m and having a total loss of 1.80609 × 10−2 dB/m at optimum frequency of 1.8 THz. Suggested PCF sensor also has effective material loss of 0.017379 cm−1 and effective area of 5.39710 × 10−8 m2. Among the principal air pollutants that can irritate and make respiration tough is SO2 and prolonged exposure could be a factor in permanent breathing problems. It also contributes to the development of acid rain, which damages aquatic environments. Therefore, it becomes necessary to detect this harmful gas and that can be effectively done with the proposed PCF sensor. The suggested PCF sensor can be crucial to minimise the air pollution rate. It will play a vital role for the improvement of human health safety from this deadly element.

Improvement in non-linear electrical conductivity of silicone rubber by incorporating zinc oxide fillers and grafting small polar molecules 通过加入氧化锌填料和接枝小极性分子改善硅橡胶的非线性导电性能

Silicone rubber (SiR) is commonly used in reinforced insulation parts for high-voltage direct current (HVDC) cable accessories due to its excellent insulation, elasticity, and high-temperature resistance. HVDC cable accessories always suffer from the local electric field concentration due to the electrical conductivity mismatch between reinforced insulation and main insulation, which can ultimately lead to electric breakdown. The non-linear conductive composites based on SiR have the ability to adaptively adjust the distribution of the electric field in cable accessories. This is expected to solve the problem of localised electric field concentration. The zinc oxide (ZnO) and glycidyl methacrylate (GMA) are used as fillers and grafted modifier respectively to improve the non-linear electrical conductivity of ZnO/SiR-GMA composites. The results indicate that grafting GMA can increase electrical conductivity of SiR, while doping ZnO filler enables SiR to have non-linear conductivity characteristics. The combination of doping and grafting modification of the composites achieves excellent non-linear conductive properties at lower ZnO filler content. Additionally, the mechanical properties of the modified composites are enhanced. The simulation results indicate that ZnO/SiR-GMA is the most effective material for homogenising the electric field when used as reinforced insulation for cable intermediate joints.

硅橡胶(SiR)具有优异的绝缘性、弹性和耐高温性,因此常用于高压直流(HVDC)电缆附件的增强绝缘部件。由于增强绝缘和主绝缘之间的导电性能不匹配,高压直流电缆附件总是存在局部电场集中的问题,最终可能导致电气击穿。基于 SiR 的非线性导电复合材料能够自适应地调整电缆附件中的电场分布。这有望解决局部电场集中的问题。氧化锌(ZnO)和甲基丙烯酸缩水甘油酯(GMA)分别用作填料和接枝改性剂,以提高 ZnO/SiR-GMA 复合材料的非线性导电性。结果表明,接枝 GMA 可提高 SiR 的导电性,而掺杂 ZnO 填料可使 SiR 具有非线性导电特性。复合材料的掺杂和接枝改性相结合,可在较低的氧化锌填料含量下实现优异的非线性导电特性。此外,改性复合材料的机械性能也得到了提高。模拟结果表明,在用作电缆中间接头的增强绝缘材料时,ZnO/SiR-GMA 是均匀电场的最有效材料。

A key factor in ensuring the efficient and safe operation of power transformers is the early and accurate diagnosis of incipient faults. Among the tools available to achieve this goal, dissolved gas analysis (DGA) is widely used by power transformers' maintenance professionals. It is a preventive maintenance tool, used for condition monitoring, fault diagnosis and unplanned outage prevention. With the development of artificial intelligence (AI), many intelligent-based methods using AI tools have been proposed in the literature for DGA data interpretation. Although these methods achieve high diagnostic accuracies and improve DGA efficiency, they are generally complicated and the research documented in these publications is difficult to replicate. Traditional DGA-based methods are simple, easy to understand and implement, and widely used by power transformers' maintenance professionals. Many methods proposed in recent years overcome the limitations of the pioneer methods and are increasingly effective. The authors present a detailed and comprehensive literature review of the traditional DGA-based methods for mineral oil-immersed power transformer faults diagnosis. This review also addresses ways to improve the efficiency of the available traditional methods. Some pitfalls that need to be taken into account to improve the efficiency of the DGA-based diagnostic methods are also presented.

确保电力变压器高效安全运行的一个关键因素是及早准确地诊断出初期故障。在可用于实现这一目标的工具中,溶解气体分析 (DGA) 被电力变压器维护专业人员广泛使用。它是一种预防性维护工具,用于状态监测、故障诊断和意外停电预防。随着人工智能(AI)的发展,文献中提出了许多使用人工智能工具的基于智能的 DGA 数据解读方法。虽然这些方法能达到很高的诊断精度并提高 DGA 效率,但它们一般都很复杂,而且这些出版物中记录的研究很难复制。传统的基于 DGA 的方法简单、易于理解和实施,被电力变压器维护专业人员广泛使用。近年来提出的许多方法克服了先驱方法的局限性,而且越来越有效。作者对基于 DGA 的矿物油浸式电力变压器故障诊断传统方法进行了详细而全面的文献综述。这篇综述还探讨了如何提高现有传统方法的效率。此外,还介绍了提高基于 DGA 诊断方法效率所需注意的一些误区。

Transmission lines and outdoor substations are replete with various forms of micro energy such as wind energy, solar energy, and electromagnetic energy. There exists micro energy in the forms of mechanical vibrations, temperature differences, and humidity in power distribution equipment. Innovative sensor or monitoring methods are needed to maintain the stability and digitisation of the grid. Unfortunately, there is limited study on the power supply of these sensor systems. Triboelectric nanogenerators, which are environmentally friendly and use simple materials, show excellent performance in environmental nano‐energy collection and self‐powered online monitoring. Therefore, environmental energy collection systems based on triboelectric nanogenerators are one of the selected methods to convert magnetic energy in the magnetic field into electrical energy. A model structure was designed using the contact separation mode, which is one of the four working modes of triboelectric nanogenerators, based on the strength of the magnetic field in the environment. This structure mainly consists of the friction layer, electrodes for current conduction, and connected loads. The research includes a comparison of four inherent electrical outputs of the triboelectric nanogenerator: open‐circuit voltage, short‐circuit current, capacitance, and power. COMSOL Multiphysics software was used for all modelling and simulation of the TENG. This software was used for the design, material selection, and static study of the TENG. When the relative dielectric constant was fixed, the output voltage reached and the energy reached . Overall, ideal reference can be provided for researchers studying power supply issues for sensors in complex magnetic field situations and help them design high‐performance TENGs.

The fibrids in aramid insulation paper exhibit good adhesion ability. However, the effects of fibrids morphology on the mechanical and electrical properties of aramid insulation paper remains poorly understood. Aramid fibrids with different morphological structures were prepared by modifying the preparation process, and then they were used to fabricate aramid composite insulation paper under the same condition. The results showed that increasing the shear rate and aramid solution concentration affected the magnitude of the shear force and double diffusion process, thus affecting the average length, specific surface area, and crystallinity of the fibrids.

芳纶绝缘纸中的纤维具有良好的粘附能力。然而,人们对纤维形态对芳纶绝缘纸机械和电气性能的影响仍然知之甚少。通过改进制备工艺,制备出不同形态结构的芳纶纤维,并在相同条件下用于制造芳纶复合绝缘纸。结果表明,提高剪切速率和芳纶溶液浓度会影响剪切力的大小和双重扩散过程,从而影响纤维的平均长度、比表面积和结晶度。当转子频率为 25-30 赫兹、溶液浓度为 15%时,纤维的比表面积大,同时结晶度高,有利于提高击穿强度。当纤维的平均长度为 0.8-1.4 mm、细度含量为 1.3%-2.3%、比表面积为 57.5-62 m2 g-1、结晶度为 18.5%-27% 时,芳纶复合绝缘纸具有最佳的机械和电气性能。结合微观形态测试结果,得出了纤维性能对芳纶复合绝缘纸机械性能、介电性能、交直流击穿强度的影响机理。该结果对高性能芳纶复合绝缘纸的制备和应用具有重要的理论意义和实用价值。

Self-healing polyurethane diacrylate (PUDA) composites with outstanding thermal conductivity were prepared with variable boron nitride (BN) and a small number of graphene nanoplatelets (GNPs) (1 wt%). The thermal conductivity of PUDA composites containing 1 wt% GNPs and 29 wt% BN reached 1.73 W/(m·K), showing 27.2% increment compared to PUDA composites only with 30 wt% BN. BN and GNPs mutually promoted the dispersion in the PUDA matrix, and the small number of GNPs was enough to bridge the gaps between BN, so that GNPs and BN exerted a synergistic enhancement effect on the thermal conductivity of PUDA composites with a synergistic efficiency of 1.343. The PUDA composites maintained the tensile strength of 8.21 MPa with good electrical insulation (4.55 × 109 Ω cm). The high degrees of recovery of mechanical strength (>90%) and thermal conductivities (>84%) were also realised by the healing effect of the reversible DA reaction. The PUDA composites with excellent comprehensive properties show broad application potential in the thermal management of electronic devices.

利用可变氮化硼(BN)和少量石墨烯纳米颗粒(GNPs)(1 wt%)制备了具有出色导热性能的自愈合聚氨酯二丙烯酸酯(PUDA)复合材料。含有 1 wt% GNPs 和 29 wt% BN 的 PUDA 复合材料的热导率达到了 1.73 W/(m-K),与仅含有 30 wt% BN 的 PUDA 复合材料相比提高了 27.2%。BN 和 GNPs 相互促进在 PUDA 基体中的分散,少量的 GNPs 足以弥合 BN 之间的间隙,因此 GNPs 和 BN 对 PUDA 复合材料的热导率产生了协同增强效应,协同效率为 1.343。PUDA 复合材料保持了 8.21 MPa 的拉伸强度和良好的电绝缘性(4.55 × 109 Ω cm)。通过可逆 DA 反应的愈合作用,还实现了机械强度(大于 90%)和热导率(大于 84%)的高度恢复。具有优异综合性能的 PUDA 复合材料在电子设备的热管理方面具有广阔的应用前景。

Improving the dielectric properties of polypropylene for metallised film capacitors based on cyclic olefin copolymer blending 基于环状烯烃共聚物混合物改善金属化薄膜电容器用聚丙烯的介电性能

High conductivity loss and low breakdown strength of traditional polypropylene (PP) film in the high-temperature environment are the key factors limiting the application of metallised film capacitors (MFCs). The effect of cyclic olefin copolymers (COCs) with different glass transition temperatures (Tgs) on the dielectric performance of PP/COC composites at high temperature are studied. The results showed that the addition of COC enhanced the intermolecular interaction force, which led to the reduction of defects in the films. In addition, COC with high Tg inhibits the movement of molecular chains and enhances the thermal stability of the film, which limits the transport of carriers at high temperatures. The conductivity and breakdown strength of the modified films (with a Tg of 134°C for COC) at 125°C are 91.6% lower and 45.7% higher, respectively, than that of pure PP. This method shows great potential in improving the dielectric properties of PP at high temperatures.

传统聚丙烯(PP)薄膜在高温环境下的高电导损耗和低击穿强度是限制金属化薄膜电容器(MFC)应用的关键因素。研究了不同玻璃化转变温度(Tgs)的环烯烃共聚物(COC)对 PP/COC 复合材料高温下介电性能的影响。结果表明,COC 的加入增强了分子间的相互作用力,从而减少了薄膜中的缺陷。此外,高 Tg 的 COC 可抑制分子链的运动,增强薄膜的热稳定性,从而限制载流子在高温下的传输。改性薄膜(COC 的 Tg 为 134°C)在 125°C 时的导电率和击穿强度分别比纯 PP 低 91.6% 和高 45.7%。这种方法在改善 PP 在高温下的介电性能方面显示出巨大的潜力。

Film capacitors are playing an increasingly important role in power-related fields, driven by the continuous development of dielectric materials and practical needs. Long-term accumulation has also led to an increasing wealth of data related to film capacitors. Sonification opens up a new way for people to make good use of data from film capacitors. A framework for sonifying film capacitors data based on TwoTone is presented. Based on the analysis and discussion, it is clear that the sonification results can easily represent the monotonic variation pattern of film capacitors data. What's more, the sonification results increase the possibility that people pay attention to the changing trend of film capacitors data when there is no significant difference in the visual perception of the data. In addition to providing a new way of music generation of electrical equipment, the method proposed is expected to contribute to theory reference in typical scenarios, such as factory calibration of film capacitors, monitoring of film capacitor operation status, and presentation of statistical data of film capacitors' dielectric materials, which will help us to better understand the distribution characteristics of polymer films.

在介电材料不断发展和实际需求的推动下,薄膜电容器在电力相关领域发挥着越来越重要的作用。长期的积累也使得与薄膜电容器相关的数据日益丰富。声学技术为人们充分利用薄膜电容器的数据开辟了一条新途径。本文介绍了基于 TwoTone 的薄膜电容器数据声化框架。通过分析和讨论,我们可以清楚地看到,声化结果可以轻松地表示薄膜电容器数据的单调变化规律。更重要的是,当人们对薄膜电容器数据的视觉感知没有明显差异时,声化结果增加了人们关注薄膜电容器数据变化趋势的可能性。除了提供一种新的电气设备音乐生成方式外,所提出的方法还有望在典型场景中为理论参考做出贡献,例如薄膜电容器的工厂校准、薄膜电容器运行状态的监测以及薄膜电容器介电材料统计数据的呈现,这将有助于我们更好地了解聚合物薄膜的分布特性。
