The starter has protective functions of short-circuit, overload, phase loss, overvoltage and current leakage etc.

Purpose

QBZ-200(120,80)/1140(660,380) mining explosion-proof vaccum electromagnetic starter is suitable to the coal mine well with explosive mixed gas containing methane.

In the power supply grid of AC50 Hz , rated voltage 1140 V and below and the natural point not grounded directly, the product can control triphase squirrel cage asynchronous motor nearby or remotely .

The starter connects with KJ254 mining power monitoring system to achieve to achieve automatic control and monitoring equipment remotely ,lastly ,to achieve noboby is on gard of monitoring.

Technical features

1)    protector is adopted WDB microcomputer control device, protective function reliable and sensitive, the precision of measure high;

2)    strip-type character LCD, automatic shading light, real time display triphase current and fault state etc.;

3)    the setting is through the three digit code and the rated current can be modified and set

4)    with the protective functions of short circuit,over load,phase failure,triphase imbalance, creepage interlock, over voltage absorbtion;

5)    with the function of fault alarm;

6)    the installation measurement of the protector conforms to JDB-80,120,200,,users can upgrade the original stater easily,just replacing the protector;

7)    with  RS485 standard interface, the product is configured in KJ254mining power monitoring system to achieve functions of remote survey,remote control,remote adjust .

lastly, user can achieve the automation of power supply device.
