Flameproof and intrinsically safe type for miningPermanent magnetVacuum feed switch


Purpose and scope of useApplication and range of application

This series of flameproof and intrinsically safe permanent magnet vacuum feed switches for mining are suitable for underground coal mines with explosive methane - air mixtures. In an AC power supply network with a frequency of50Hz, rated voltage of1140V and below, where the neutral point is ungrounded, they can be used as main distribution switches, branch switches, or for infrequent motor starting. When connected to the automatic control and comprehensive automation system for mining power, they can achieve remote automatic control and monitoring, enabling unattended operation.


Product featuresProduct features

It adopts a quick-opening door structure and features a full Chinese display, which can display real-time parameters of the system such as three-phase voltage, three-phase current, active power, reactive power, insulation resistance, power consumption, and number of switch-on times.

It uses a pull-down menu for parameter setting and has the function of parameter setting and modification. The parameters of the switch can be accurately modified and set with a step size of 1.

The switch has multiple protection functions such as short-circuit protection, overload protection, leakage blocking, phase failure protection, three-phase unbalance protection, leakage protection, under-voltage protection, and over-voltage absorption.

It has functions such as wind-power and gas locking, high-voltage electrical interlocking, temperature alarm, and remote opening.

The remote control uses intrinsic safety control. The intrinsic safety parameters are: voltage 21.8V(AC), current 78mA(AC).

It is equipped with standard 4G, wifi, TCP/IP, 485, and LoRa communication interfaces, which can be selected according to customer needs. When configured in the mine power automatic control and comprehensive automation system, it can realize the four-remote functions of remote measurement, remote control, remote signaling, and remote adjustment, achieving automation of power supply equipment.

It uses a permanent magnet (bistable) vacuum circuit breaker, which has the characteristics of simple structure, easy maintenance, fast response speed, stable operation, and long service life.
