High voltage vacuum switch for mine flameproof mobile substation
1.Application
This series of products are suitable for underground coal mine with explosive dangerous gas (methane mixture), and can be used together with mobile substation.
2.Technical features
High voltage vacuum switch and low voltage side protection box used in mobile substation adopt programmable controller (PLC) and text display screen as the control and human-computer interaction system. The panel is equipped with liquid crystal display window, which can display the running state of switch and various fault states. The panel is also equipped with parameters setting, overload, short circuit, power distribution button, for parameter setting and functional operation. The product parameter setting is flexible and convenient, the quality is stable, the movement performance is sensitive and reliable, the operation and the fault screen is intuitionistic and concise.
Mobile substation with high voltage load switch main components of the new air type high voltage load switch, with a large breaking current, simple structure, safe and reliable, suitable for frequent operation and other characteristics. Thanks to the new type of arc extinguishing mode, it ensures that the touch knife is not easy to be damaged, improves the ability of connection and analysis, has good dynamic and thermal stability, high insulation level, easy operation and reliable action.
3.Protection function
The high voltage vacuum switch for mobile substation has protection functions such as overload, short circuit, phase break, over voltage, under voltage and over temperature.
The high voltage load switch used by the mobile substation is equipped with emergency stop superior power contact and low-voltage side feed blocking contact. Door opening and locking switch and other protective functions.
Mobile substation with low side protection box with overload, short circuit, leakage, over voltage, under voltage, electrical rating control and protection functions.
