Which explained "" overcurrent trip behavior: as the relay for other contacts are fine speed controller and current regulator of input and output signal both the normal value of zero growth of the original does not work contact for some reason (such as vibration, etc.) to work, all of a sudden phase-limiter had lifted the blockade and the output signal, so that the larger main motor Haar "" transflux arising from the trip.

由此也可注释呈现&功不源&跳闸本体的来因：由于该继电器的其他触不面均处事精良，速率调度器和电不源调度器的不不不不不不不输入、不不不不不不不输入暗记均呈变态的由不整到必不退值的落低，而本来不处事的触不面由于某种来因猝然又处事了，移相限制器便因撤废敞开而不不不不不不不输入较大暗记，使宾电机不不矮速启不静而呈现&功不源&跳闸本体。
