QJZ Vacuum Electromagnetic Starter Introduction
QJZ series mining explosion-proof and intrinsically safe vacuum electromagnetic starter is mainly suitable for the coal mine, as a long distance or direct control of ac 50 hz, voltage 1140 v mining flame-proof three-phase squirrel-cage asynchronous motor start and stop. And when to stop, to change the control power of the motor phase operation..Starters with overload, phase failure, short circuit, over-voltage leakage blocking and absorbing protection, the starter can achieve a single remote control, local control, dual interlock control as well as multiple starters positive sequence starting.
QJZ Vacuum Electromagnetic Starter Structure
Side shell mounted on the skid-shaped square flameproof enclosure chassis, body assembly, the front door and electrical parts and assembly parts.
Including AC vacuum contactor, current transformer, the RC absorption devices, control transformer, fuses, isolation for the switch, emergency stop button, fuse, intrinsically safe control relay, relay, protection, toggle switch, start button , stop button, emergency stop button between the mechanical locking device. Wiring chamber with the main circuit input terminals, outlet terminals, control lines, terminal blocks, stop and start button and the reset button, the signal display window XS components.
