Mine Explosion-proof and Permanent Magnetic High-Voltage Vacuum Distribution Equipment

Applications

The high-voltage vacuum distribution equipment is suitable to provide reliable control and protection for insulated neutral or arc suppression coil grounding power supply and transforming system under the coal well with explosive gases and coal soot, with the rated voltage of 10kV, rated frequency of 50Hz and rated current of

630A. Besides, its also suitable for direct starting the electro-motor. The device has 4 structures of a, b, c, d , to enable different application modes such as power receiving, power feeding, contact, networking, and direct control and so on.

Features

1. The advanced CPU technology is adopted in the protector, which has enhanced function independence of individual parts and practicability of the system. Besides, the high-resolution A/D converter and the detection method of single measuring range are also used in the device, which has greatly enhanced the accuracy of data collection;

2. It adopts blue-backlight Chinese LCD display, which enables data display and all operations more intuitive;

3. It has the function of detection and display of the power factor and degree of imbalance between the phases as well as display of electricity consumption (active component) and real-time clock and so on;

4. The high-voltage vacuum circuit breaker with spring mechanism is adopted for breaking principle components;

5. It can provide protection in such cases as overload, short circuit, electricity leakage, insulation monitoring, overvoltage,undervoltage, three-phase imbalance etc.;

6. It has the RS485 communication function, which can network 2~999 protectors into the LAN or Internet with connectors.
