As shown in the figure, it is a single-phase lighting dual-channel automatic switching power supply line. When the No. 1 power supply fails for no reason, the backup power supply can be automatically switched on. In the figure, 1K and 2K are small switches , and 1C and 2C are AC contactors. When working, first close the switch 1K, the AC contactor 1C is closed, and the power supply is powered by No. 1 power supply. Then close switch 2K, because 1 and 2C are interlocked, at this time, 2C will not pull in, and power supply 2 is in standby state. If power supply No. 1 is cut off for some reason, AC contactor 1C is released, its normally closed contact is closed, the coil circuit 2C is connected, 2C is closed, and power supply No. 2 is put into power supply. You can also close switch 2K first and then switch 1K to make power supply No. 1 a backup power supply.
