CQJGZ Series Mining Falme-proof and Intrinsic-safety High-voltage Vacuum Electromagnetic Starter
Application
This serial of product can be used used in the environment which is full of dangerous gas like methane, under the rated voltage of 10kV, 6kV, the rate is 50Hz, rated current 50A-630A, can be used as the high voltage starter.
Features
Adopting vacuum contactor, the inter feel machine, reasonable in structure, no need to add the additional rail,strong connection,easy to install and maintain.
Adopting 32-bit micro processor, high protection precision and respond speed, equipped with grounded, under pressure, over pressure,three phase unbalance, overloaded short circuit, break phase insulation supervision and auto lock function.
The voltage, current, working rate, electricity and resistance will be displayed on the screen.
Adopting RS-485 or CAN connector, the communication between the monitoring system and the machine can be realized, equipped with “four remote” function, the real no guard can be realized.
Equipped self detecting function, if any error occurs ,the system will give the according information.
The design of quick-open door is equipped reliable mechanical and electrical interlock and ensures safety and reliability.
The electricity control device can be used singularly but also can be used with another one.
