Background
In production and life, in order to avoid operation stagnation caused by power failure, a standby power supply is often arranged, and a bypass switch is arranged to switch a power supply line to the standby power supply after the main power supply fails. When the current bypass is put into operation, a cable channel of the I-path bypass is firstly introduced into the original transformer return process, so that a user low-voltage switch is bypassed by the cable channel, then the user low-voltage switch is disconnected, and then the input of the I-path bypass is switched to the input of the II-path bypass by one key; when the bypass exits, the input of the II path is switched to the input of the I path by one key, then the low-voltage switch of the user is closed, the new transformer is put into operation, and the short-time power failure caused by switching operation of the low-voltage switch is eliminated. The short-time power failure time is reduced from 13 minutes in the traditional method to the switching time of two switches of 1 second.
However, when the bypass is switched back and forth, the power of the customer still needs to be cut off for 1 second each time, and the household appliances are still shut down, the elevator is shut down, and the computer is still halted.
