有界波模拟器中线缆倾角对电磁耦合的影响
The influence of the cable slop angle on electromagnetic coupling in bounded-wave simulator
摘要
Abstract
The breaker,disconnector and other primary equipment in power equipment are getting closer to the secondary equipment.The sudden change of the electromagnetic field caused by switching operations of the primary equipment reduces the reliability of the secondary equipment.For example,the opening and closing operations of the disconnector in the substation generate strong transient electromag-netic pulses.Part of the energy carried by the electromagnetic pulse couples with the cable which is exposed outside of the secondary e-quipment,flows into the equipment,and interferes with the internal electronic devices.In severe cases,the strong transient electromag-netic pulses lead the device to fail and the equipment to work abnormally.In order to clarify the coupling mechanism of the electromag-netic pulse to the cable,the transient electromagnetic field generated by the switching operation of the disconnector in different voltage-level substations are measured in situ and collected,and the typical waveform of the pulse is extracted and reproduced approximately by a bounded-wave simulator in laboratory.The influence of the cable placement angle on electromagnetic coupling to the cable in bounded wave simulator is studied,which provides a reliability testing theory for chips worked in complex electromagnetic environment.关键词
