Square shell, quick opening structure and modular movement. Simple and reasonable structure and convenient operation.

Combination of WZBQ-8QG microcomputer integrated protection unit, WZBQC integrated control unit and industrial control technology realize the advanced mode of decentralized protection and centralized control, which is of powerful function, stable performance and friendly interface.

The internal data of the product adopt optical fiber communication, which ensures the normal high-speed transmission of signal and eliminates the phenomena of crash, maloperation and disorder code.

The touch screen of 10 inch TFT color industrial computer is used to display the important parameters such as system voltage, three-phase current, circuit running state, circuit on-line state, fault type and so on. With fault memory and inquiry function. With man-machine interface keyboard, can amend fixed protection value without power failure and various kinds of operations.

The intelligent microcomputer integrated protection device has the functions of overload, short circuit, leakage blocking, phase interruption,unbalanced three-phase, under voltage and over voltage absorption.

Main cavity, incoming cavity, outlet cavity, external lead intrinsically safe cavity, control transformer cavity, each chamber is independent,reasonable layout, safe and convenient maintenance and assembly. Auxiliary power supply of 127V(4kVA),220V (1kVA) is provided, and the line is protected by vacuum contactor and microcomputer integrated protector.

With standard LAN communication interface, it is configured in mine monitoring and monitoring system to realize 4 remote functions, namely telemetry, remote control, remote communication, remote adjustment. Can realize the functions of remote dividing, closing, remote reading of meter, thus to achieve unattended operation in the substation.
