In this paper, the characters of the vacuum arc parameters in 270V DC forcing interruption were investigated. In which we considered some factors, such as the forcing frequency, the rate of the current and voltage at zero passage (di/dt, dv/dt), the charging voltage of the commutation circuit capacity, and the current magnitude. The experiment was performed on a synthetic test circuit, which composed by the RC main current circuit, LC commutation circuit and a cup type AMF contactor, which electrodes' diameter is 66mm, and gap is 4mm and a plane one for miniaturization use. The experiment showed that with the forcing frequency increases (2.3 kHz, 3.1 kHz, and 4.2 kHz) and other factors the same, the forcing arc duration decreased obviously, and the rate of the di/dt raised. Meanwhile the peak of the arc overvoltage raise, the voltage noise get smooth, and the inverse arc current peak increase. In other experiments, we fixed the di/dt. Under the same circuit parameters, the current magnitude influenced the current and voltage peak value, And the charging voltage determine the arc duration. 3 types waveform for the failure interruption, and the di/dt-dv/dt characteristics was investigated. And finally compare the obviously difference of post-arc current between AMF and plane VI, The knowledge may guides us to optimize a smaller apparatus for utility use.

Vacuum bulbs may encounter the pressure rise hazard that results in failure in interrupting over currents in power systems. The pressure may unexpectedly increase due to a slow leak through cracks after a long period of operation in the power system. Several methods for monitoring the pressure onsite have been proposed so far, but most of them are poor in the ability to checkup the hazardous pressure level of 1 Pa or less. The present paper reports the results of a primitive attempt conducted for diagnostic purposes. In the study, by monitoring the electrification on the insulator surface of a real vacuum bulb, we successfully provide a method to detect the pressure rise around 10−1 Pa.

This paper focuses on the numerical investigation of arc plasma behaviour in arc chamber of direct current (DC) circuit breaker. A 3-D simulation model of arc chamber including ferromagnetic splitter plates is built and calculated, which is based on magneto-hydrodynamics theory. Coupled electromagnetic and gas dynamic interactions are considered as usual, and a thin layer of nonlinear electrical resistance elements is used to represent the voltage drop of plasma sheath and the formation of new arc roots. Therefore, the arc-splitting process with ferromagnetic plates can be included. To reduce the time consuming, the arc simulation results of arc commutation process from contact to arc runner is taken as the calculation initial condition in the model. Arc motion is described in detail by the temperature distribution. Moreover, the simulation result is compared with experimental result, which shows good agreement.

For studying the effect of the pressure on the breaking performance during the cold gas interruption of a SF6 circuit breaker (CB), 1D compressive gas flow field mathematical model was deduced by replacing the mass equation with the pressure equation based on the mathematic transformation. And the distribution of Mach number in gas flow field under different opening strokes were simulated using finite volume method (FVM), and the density, the pressure, the velocity, and the temperature distribution of the gas flow were obtained and especially the above gas flow parameter variations at the region of the shock wave formed have been calculated. And the fundamental solution of the equations describing the gas flow in the SF6 CB has been resolved using separation of variables method, and 1D differential equations with constant coefficient were derived. Based on the proposed model, the bifurcation diagrams at different opening strokes have been calculated. The results show that for the gas flow with different velocity, the system exhibits periodic, quasi-periodic or even chaotic behavior in the arc quenching chamber. And the instability of the shock wave may be one of the origins of the complex phenomena.

The design of aerospace electromagnetic relay is complicated and the process refers to the multi-fields problem including the kinematic, electricity, magnet and thermal. Aim to the problem, a new modeling language named RML and a distributed simulation method were proposed for the design of the aerospace electromagnetic relay. Through the secondary development of the related software, such as FLUX, ANSYS, ADAMS et al., the model of the relay built by RML could be recognized by any software above. The integrated simulation system of the aerospace electromagnetic relay was developed by the C++ Builder software. The system has the functions of the parameter design and kinematic analysis.

Detection of SF6 gas decomposition products has been increasingly used for monitoring the insulation condition of Gas Insulated Substation (GIS) for its advantages, comparing to traditional partial discharge detection methods, such as excellent anti-interference ability, explicit calibrating method and so on. In this paper, based on the setup of two typical GIS defect models including needle-to-plate and insulator surface, gas decomposition products were detected by IRprestige-21 Fourier transform infrared (FTIR) spectrophotometer. Types, concentrations and trends of typical gas decomposition products were analyzed. Moreover, influences of acquisition and transportation duration on detection results were studied. Obvious differences were found among infrared spectra of gas decomposition products from different defect models, which verifies the feasibility of IR gas decomposition detection method for GIS fault detection and diagnosis.
