PLC (programmable logic. controller) programmable control cabinet is an electrical cabinet that can be programmed according to the needs of operating conditions, and can realize the automatic control of motors, switches and other equipment
This product is suitable for an environment with coal mine gas, coal dust, and other explosive gases underground, to logically control the start, stop and double-speed of the three-phase AC asynchronous motor or AC double-winding motor in the circuit of AV 1140V or 660V. And it has a joint control function.
The device is used in coal mines containing explosive gas (methane) and coal dust. It is suitable for the circuit of AC 50Hz, voltage 660V or 1140V, ungrounded three-phase center. To local control or remote control the start and stop of three-phase asynchronous motor, and can be reversed at the stop.
ZJZ-16/1140(660)SM-2 This device is suitable for underground coal mine containing coal dust and explosive gas (methane). It can control the power supply of 127V grade lighting signal equipment, and the power supply is introduced as 50 Hz 1140V or 660V.
The device is used in coal mines containing explosive gas (methane) and coal dust. It is suitable for the circuit of AC 50Hz, voltage 660V or 380V, ungrounded three- phase center. To control the forward and reverse rotating of three-phase asynchronous motor.
KJZ-500,630/1140(660) Mining explosion-proof and intrinsically safe vacuum feeder switch.Used in coal mines, in AC 50Hz, rated voltage of 660V or 1140V, rated current to 500A(630A) three-phase neutral point undergrounded power supply system, as a main switch or branch switch, but also as a large-capacity motor infrequently for starting control.
The device is used in coal mines containing explosive gas (methane) and coal dust. It is suitable for the circuit center. To local control or remote control the start and stop of AC 50Hz, voltage 1140V, 660V or 380V, ungrounded three- phase asynchronous motor, and can be reversed at the stop.
