2.Hein's installation is a wall of neon lights that switch off as the viewer approaches.
这是一个由霓虹灯组成的墙，当观众靠近它时它便会关上。
3.In a10kV distribution system,when shunt ca-pacitors are switched off by vacuum circuit breakers,restrike overvoltage often occurs.
电力系统中路器切除无功补偿并联电容器时,容易产生重燃过电压,严重影响并联电容的安全运行。
4.This paper describes the mechanism that multiple reignition of breaker can restrain or increase progressively the switching-overvoltage during switching off inductive or capacitive load.
