Abstract

In gas insulation switch (GIS) substation, secondary devices such as line monitoring devices are placed in the switching field, and these electronic devices are vulnerable to transient electromagnetic interference caused by switching operation. In order to facilitate the measurement and research of electromagnetic disturbance data under different working conditions, a simulation test device is developed in this paper, which can be used to simulate electromagnetic disturbance of GIS substation sensor and secondary device port under switch operation. A four-channel parallel gas switch was designed, and the main characteristic parameters of electromagnetic disturbance generated by the simulation device were measured by using high-frequency pulse power supply as the excitation source. The comparison between the measured waveform and the measured disturbance characteristic parameters of GIS substation shows that it is in good agreement with the measured waveform characteristics, conforms to the basic characteristics of damped oscillation wave, and can be used in the secondary equipment port disturbance voltage coupling characteristics, protection measures evaluation and assessment method research.
