Anti-override trip device

In the power supply system of our country, the low-voltage distribution system drops the transmission voltage of the power grid to the distribution voltage, and then transmits it to the low-voltage distribution equipment through the distribution line. At present, low-voltage distribution lines often cause voltage loss, overvoltage, overload and short circuit due to a large number of loads. Moreover, due to the short distribution lines and many extension stages, they will also cause the distribution lines to trip over the level and cause great pressure on the distribution system. Therefore, it is necessary to use the "anti-trip" method and system to protect the distribution lines and distribution systems.

Therefore, it is necessary to use the "anti-trip" method and system to protect the distribution lines and distribution systems.
    The device adopts current acquisition and outlet corresponding settings, the action is reliable and sensitive. The device has a friendly man-machine interface, simple and easy to understand menu settings, easy to achieve detailed data acquisition, parameter settings, event recording, debugging and other functions. The device can also be networked with the background system through the communication line to realize the remote monitoring function, save a larger amount of historical data and historical event records. It can solve the problem of large-area power failure caused by PC leapfrog trip caused by non-metallic grounding, plastic shell switch and thermal relay in MCC line.
