The utility model can automatically switch to the loop of the standby power supply when the normal power supply is in power failure.

At the initial power-on, the initial states of the KM1 contactor 13 and the KM2 contactor 14 on the main loop are released.

When the normal power supply supplies power, the terminals R1 and S1 of the normal power supply module 9 have AC380V power, after the power passes through an F1C air switch 21, the power is supplied to the KA1 contactor 23, the KA1 contactor 23 is attracted, the normally open contact of the KA1 contactor 23 is closed, the power passes through the normally closed contact of the KM2 contactor 14, so that the KM1 contactor 13 is electrified and attracted, and the power is output to the R, S, T terminal of the power output module 12 from the terminals R1, S1 and T1 of the normal power supply module 9 through the KM1 contactor 13, thereby realizing the normal power supply.

When the normal power supply is disconnected in the event of a power failure, the KM1 contactor 13 loses power and releases, and the standby power supply (generally provided by a standby diesel generator) is waited for.

After the standby power module 10 starts to provide power, AC380V power is provided at the R2 and S2 terminals of the standby power module 10, after the power passes through the F2C air switch 22, the power is provided to the KA2 power-on delay contactor 24 for supplying power (power-on delay is set to 1S), the KA2 power-on delay contactor 24 is pulled in, the KA2 power-on delay contactor 24 delay contact is closed at the normally open contact after being powered on for 1S, after passing through the KM1 contactor 13 normally closed contact and the KA2 power-on delay contactor 24, the KM2 contactor 14 is powered in and pulled in, the power is output from the R2, S2 and T2 terminals of the standby power module 10 to the R, S, T terminal of the power output module 12 through the KM2 contactor 14, and the standby power supply is realized.

The electric protection circuit when this device design two sets of powers is effective simultaneously, under the condition of stand-by power supply, if normal power supply incoming telegram this moment, the system continues to keep stand-by power supply under the effect of delay circuit this moment, switches to normal power supply after the power supply 1s again, can not cause the condition of the simultaneous power supply of two sets of powers. The time sequence is as follows, the corresponding KM1 contactor 13 cannot be pulled in at the moment because the coil is internally connected with the normally closed contact of the KM2 contactor 14 in series. In the corresponding circuit of the KA3 electrified delay contactor 25 (the electrified delay is set to be 1s), after the normally open contact of the KA1 contactor 23 is closed, the KM2 contactor 14 is closed, the KA3 electrified delay contactor 25 is attracted, the corresponding time delay contact of the KA3 electrified delay contactor 25 is attracted after being electrified for 1s, the coil circuit of the KM2 contactor 14 is cut off at the moment, the standby power supply circuit is cut off after the KM2 contactor 14 is released, then the corresponding KM1 contactor 13 starts to be attracted, and the normal power supply starts to supply power.

In order to prevent power supply conflict caused by simultaneous attraction of the KM1 contactor 13 and the KM2 contactor 14, a mechanical interlocking device is additionally arranged between the KM1 contactor 13 and the KM2 contactor 14 in the design of the device, and only one of the KM1 contactor 13 and the KM2 contactor 14 can be attracted at any time.

A locking device, namely a door lock 5, is designed at the box door 1, and after an F1C air switch 21 and an F2C air switch 22 in the box body 2 are disconnected, the box door 1 can be locked through a handle, so that the electric shock hazard caused by the fact that people are electrified in the maintenance process is prevented.
