Detailed Description
QBZ series mining flameproof vacuum electromagnetic starter
Scope of application
QBZ series mining flameproof vacuum electromagnetic starter is mainly suitable for explosive dangerous gas (coal mine methane and coal dust mixture), in 380, rated voltage 380 v, rated frequency 50 hz, rated current 200 a three-phase ac neutral point grounding power system directly, the flameproof three-phase squirrel-cage motor start, stop, and reverse control directly. Starting equipment is pressure, over voltage, short circuit, overload, open phase, leakage blocking protection, etc.
1, the starter USES three pole vacuum contactor, main contact seal in the vacuum switch tube, no maintenance, arc is not exposed, suitable for frequent operation, less wear of main contact, electrical life is long, safe and reliable characteristics.
2, starter, adopt the new left off, commutation action is reliable, and has improved the arcing cover, arcing effect is good.
3, have the function of the local and remote control motor starting stop, with comprehensive JDB type motor protector realizing overload, short circuit and leakage, phase locking protection.
