2.Hein's installation is a wall of neon lights that switch off as the viewer approaches.
这是一个灯组成的墙,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.
力系统中使用空断路器切除无功补偿用并联容器时,容易产生重燃过,重影响并联容的安全运行。
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.
