Abstract

Short circuit fault cause arcing fault initiate fire accident. Fire case caused by short circuit fault in low voltage installation is occured every year. Several cases in fire accident at low voltage installation caused by short circuit fault. In this case, protection equipment failed to detect and secure the installation. This experiment investigate short circuit case at low voltage filament conductor cable 1.5 mm2. Short circuit cases variated by filament or strand that experienced contact. When short circuit occurred, arcing is recorded by thermal camera. Moreover, current and voltage arcing will be synchronized with thermal arcing image. The synchronization result is analyzed to obtain the caharacteristics of arcing that consist of value of maximum temperature arcing, sectional area arcing data, and duration of arcing. These characteristics are very useful to design arcing fault detector. The result shows that the arcing temperature, area, and duration respectively are up to 100 °C, 1300 mm2, 10 seconds.

通过电弧热同步传感和短路电流分析直接短路低压电弧特性

短路故障引起电弧故障引起火灾事故。低压装置短路故障引起的火灾每年都有发生。低压装置因短路故障引起火灾事故的几个案例。在这种情况下，保护设备未能检测并确保安装。本实验研究了1.5 mm2低压灯丝导体电缆的短路情况。短路情况因灯丝或钢绞线接触而异。当发生短路时，热像仪记录电弧。此外，电流和电压电弧将与热电弧图像同步。对同步结果进行分析，得到电弧的特征，包括最高温度电弧值、电弧截面积数据和电弧持续时间。这些特性对电弧故障检测器的设计具有重要的指导意义。结果表明，电弧温度可达100℃，电弧面积可达1300 mm2，电弧持续时间可达10秒。
