DESCRIPTION

Product use

Suitable for coal mine in explosive environment, in rated frequency 50Hz, rated voltage 1140V, 660V, 380V three-phase neutral point ungrounded power supply system, the 1140V, 660V, 380V power supply into 127V lighting and signal load power supply, power control, short circuit, leakage protection as one of the comprehensive explosion-proof electrical equipment; This product realizes the functions of dual power supply 1140 (660) V input, four or two 127V power output control, etc. When the main circuit power supply loses power, the backup circuit power supply will automatically put into work; Mainly used for monitoring equipment, communication equipment, video system, lighting equipment and other uninterrupted power supply. Connected with KJ series underground coal mine power grid monitoring system, it can realize remote automatic control, monitoring and monitoring of power equipment, and realize modern management such as unattended substation.

Main feature

The shell adopts the translation quick-opening structure, small size (the interior adopts the modular design), easy and fast operation;

Dual power supply design, one power failure or power failure, can automatically switch to another power supply, to ensure uninterrupted power supply;

The AC vacuum contactor is used as the main breaking element, with strong breaking ability, safe and reliable, and the working current can be switched on and off frequently.

All Chinese, LCD real-time display system three-phase voltage, current, insulation resistance, switching state, fault information and other parameters;

The integrated protector adopts advanced microprocessor and large-capacity new chip, with high-precision data processing and advanced protection algorithm, high protection accuracy and fast response speed;

With short circuit, overload, overvoltage, undervoltage, phase break, leakage blocking and other protection functions;

With the end short circuit protection function, to ensure the reliable operation of the protector when the short circuit fault occurs at the far end of the cable;

With pilot, program, network (RS485 and Ethernet) control, flexible and convenient;

Optional configuration of RS485, CAN, Ethernet interface, 4G/5G/IFI and coal mine power grid monitoring system communication, with telemetry, remote control, remote control, remote message, remote viewing and other functions, to achieve unattended substation.
