(one)Application
KJG-400/10(6)Y Mine-used Flameproof and I.S. High- voltage Vacuum Switch for Mobile Substation is suitable for underground coal mines with explosive gases such as methane. It can control the high-voltage distribution of the mobile substation which is at 50 Hz, rated voltage 10 kV/6 kV rated current up to 400 A. It also can form an ideal mobile transformer system in which the low voltage fault disconnects the high voltage side power supply by combining with our BXB1 Mine-used Flameproof Low voltage Protection Box.
(two)Features
l. With advanced integrated microcomputer protection, it can set up protection parameters without opening the enclosure door. It has protection functions such as overload, short-circuit,monitoring, under voltage, over voltage, phase unbalance, temperature, and it can record the tripping reason for long period.
2.It has a small volume and proper structure and the switch can be switched on or off manualy or automatically.
3. It is compatible with all large capacity mobile substations (under 2500 kVA)-
4.The isolation switch is knife structure.
