英语翻译If an earthing switch is present within the generator circuit breaker cubicle or between the generator and the circuit breaker then interlock circuits (electrical and/or mechanical)should be present to prevent operation of the earthing switch when the generator is turning above turning gear speed or voltage is present.如果接地开关是在发电机断路器柜或发电机和断路器之间，当发电机转动齿轮的超速或电压出现时，应由互锁电路（电气和/或机械）防止接地开关的操作 我觉得这样翻译“当发电机转动齿轮的超速或电压出现时”，好像不对
