Overview

The mining electrical switch protection performance test bench is mainly used as a good assistant for measuring the maintenance of switches in coal mine machinery repair plants. It can provide working power and high current for various switches, as well as the action time of switches, three-phase synchronous measurement, leakage resistance test, vacuum tube withstand voltage test, etc.

Product Details

Mining electrical switch protection performance test bench

Scope of Application

Various detectable power supply switches, starters, lighting comprehensive protection, multi circuit combination switches, and individual protection devices for commonly used ones, such asJDBPerformance testing of the series. Combined with the switch body, all protectors can be tested.

It can conduct experiments on leakage lockout, leakage, overload, short circuit, phase loss, three-phase imbalance, circuit breaker synchronization, vacuum tube contact resistance, power frequency withstand voltage, etc. for each switch.

five: Usage and precautions

1: Connect three-phase four wire380VPower supply connected toBehind the equipmentterminal blockL1TheL2TheL3TheNTurn on the main power switch and panel inside the machine“Power indicator light”Bright, thenpop up“Emergency stop”All instruments are on.

2When the power is turned on, the upper right corner of the control panel'red'The indicator light is on, at this time it willLift up the 'emergency stop' button，The experiment can be conducted immediately.

3Press the panelthree-phase0-50KVbelowClose the switchControl,Simultaneously press intermittentlyBoost button, can be adjustedthree-phase050KVThe output and wiring terminals are located behind the control cabinet,“UATheUBTheUC”

4：Translate into EnglishAC0-380VZero the regional regulator first and connect itAC0-380VOutput line, thenopenAC0-380VRegional button“ON”,Conduct a voltage boost test to increase the required voltage value.

5Connect the resistor output line, then adjust the resistance and conduct the test.

6According to high current0-6300AClose the area button, then intermittently press the "current up" and "current down" buttons to achieve the desired measurement value

7On the far right side of the panel, "zeroing start" indicates that all tests need to be zeroed before proceeding, while "impact start" indicates that all tests do not need to be zeroed.

All measurements cannot be taken simultaneously, they can only be taken individually!!!
