Product Description
Product introduction:
WBB series mine explosion-proof dynamic reactive power compensation device is a special equipment for automatic reactive power compensation of low-voltage 1140V (660V) power supply system in coal mines with explosive dangerous gas (methane) and coal dust. This equipment can be used in parallel with mobile substations or dry-type transformers with a capacity of less than 1250KVA in the coal mine underground power supply system to centrally compensate for the mobile substations of fully mechanized underground mining units. It can also be used for coal mining, tunneling, development, transportation and other systems. Secondary side compensation.
The main function:
Automatically track the electrical parameters of the coal mine underground power supply system in real time, and automatically switch the compensation branch according to the set target, which is used to dynamically compensate reactive power, improve power factor, reduce line current, increase terminal voltage, filter out harmonics, and control harmonic pollution , Purify the grid, effectively improve the power quality of the grid, and achieve the purpose of energy saving and consumption reduction.
The main technical parameters:
Product design features:
1. According to the characteristics of the underground power supply system, the design is reasonable, the technology is leading, and the scope of application is wide.
2. Compensate the fundamental reactive power and have the function of harmonic control.
3. Reliable explosion-proof performance, easy to install, observe, test and maintain.
4. The controller meets the international electrical standards, and various electrical parameters are displayed on a dynamic wheel.
5. Perfect electrical protection.
6. Unique quick-opening patented technology and unitized movement design, safer to use, easy to use and easy to maintain.
7. The setting button leads to the facade, which facilitates the setting and adjustment of various parameters.
