Product Description

Application of High Voltage Mining Flameproof Intrinsically Safe Vacuum Electromagnetic Starter

This series of High Voltage Mining Flameproof Intrinsically Safe Vacuum Electromagnetic Starter for coal mine and its surrounding medium containing methane, coal dust and other mixed gas environment, the rated voltage 10kv or 6kV, rated frequency 50Hz, rated current to 400A (630A) of the three-phase AC neutral point is not directly grounded power supply system, the high-voltage motor remote or local direct start, stop, while the motor and the relevant power supply circuit protection. Starter is particularly suitable for frequent operation, heavy load coal mine machinery and equipment, and high-voltage start-up reactor or high-voltage soft-start controller supporting the use of better results. And KJ series coal mine underground power grid monitoring system connection, can achieve remote automatic control and monitoring, monitoring of power equipment, substation to achieve unattended and other modern management.


Features of High Voltage Mining Flameproof Intrinsically Safe Vacuum Electromagnetic Starter

1. The use of advanced fast open door, hand-car movement structure, highly interchangeable, light and efficient operation (and power distribution device can be used together);
2. With varistor and resistance absorption device, can effectively inhibit the high-power inductive load over-voltage operation;
3. All Chinese LCD Han microcomputer integrated protection, real-time display three-phase voltage, current, switch-like, power factor, active, reactive, electrical and so on;
4. With three-stage protection (short circuit, overcurrent, overload), over and under voltage, selective leakage protection, three-stage zero sequence current protection, insulation monitoring, three-phase imbalance, fault recorder, short circuit delay , To prevent the escalation of leaping, PT disconnection, fault memory, fault self-diagnosis and other protection functions; loss of protection by the current blocking and increase the delay set to avoid the voltage flash caused by the power distribution device voltage loss trip;
5. With three-phase power measurement function;
6. The tuning of the parameters through the three buttons or the use of mine flameproof and intrinsically safe infrared remote control, and password protection;
7. Equipped with standard RS485 or CAN communication interface, can automatically upload parameters, events, fault information, etc., it is easy to achieve networking and network communications, remote telemetry, remote control, remote, remote control and other four remote functions; System of centralized, intelligent, information management and scheduling.
