Mine & Mobile Transformer Substation Explosion-proof High-Voltage Vacuum Switch

Applications

The high-voltage vacuum switch is suitable for control and protection of the 10kV/50Hz power supply system under the mine well with explosive dangerous gases and coal soot, with the rated current of 400A. Besides, its suitable to constitute another mobile transformer substation with the high-voltage side of the mobile transformer substation and low-voltage protection box or vacuum feeding switch produced by our factory, to support the transformer with capacity of 315kVA~1600kVA, and protect the system in case of overload, short circuit, phase failure, overvoltage, undervoltage etc. and other failures in the low-voltage side.

 

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. It can provide protection in such cases as overload, short circuit, electricity leakage,

insulation monitoring, overvoltage, undervoltage, three-phase imbalance etc.;

5. It has the RS485 communication function, which can network 2~999 protectors

into the LAN or Internet with connectors.
