KPM83B 35KV 3 phase electric digital dual power generator automatic transfer switch price

Microcomputer backup power supply automatic transfer switch device is an important function of substation, which can effectively reduce the loss caused by power failure.

The wiring diagram of the automatic transfer switch device is as follows:

The automatic transfer switch usually uses the voltage loss and undercurrent as the criterion. The voltage criterion comes from the voltage transformer (the incoming voltage comes from the incoming line PT or the live display output node). If only use voltage as a criterion, the current isn’t necessary to be connected to the device.

3 phase electric digital dual power generator automatic transfer switch price main operation mode

1.      Bridge automatic transfer switch operation mode (the incoming line I and II each has a busbar and the sectional switch is disconnected).

2.      Incoming line I self-injected (input II with two-stage bus load, incoming line I as backup power).

3.      Incoming line II self-injected (the incoming line I carries the load on the two-stage bus, and the incoming line II is used as the backup power).

4.      Reverse incoming line self-injected.

 Protection function of generator automatic transfer switch price

1. Charging protection

When the bridge automatic transfer switch action closes the segmentation switch, if the current at the segment is large, it means that it is combined with the fault, then the segmentation switch is cut off by delay.

2. Incoming line joint cutting function

The joint cutting function means that when the load is applied to the entire load by the incoming line I or the incoming line II, if the load is too large, it is necessary to remove the unimportant load. The joint cutting function is divided into two time limits. If the current is greater than the fixed value, the joint and part of the load are cut off after delay T1. If the current is still greater than the fixed value, , the joint 2 and the other partial load is cut off after delay T2. The joint cut function sets the fixed value, delay and input control words for incoming line I and II independently, but the outlet is shared.
