Relay test bench

Relay comprehensive test benchUsed for action testing and setting of various types of contactors, voltage relays, current relays, time relays, intermediate relays, small circuit breakers, motor protectors, thermal relays and other switch components for railway locomotives, subways, automobiles, etc.

Main structure and function

1)RelayThe test bench can test the following electrical components of the train:

① Automatic testing of the pull in voltage, release voltage, action time, release time, coil resistance, and contact resistance of the intermediate relay.

② Time relay delay time and automatic testing of contact resistance.

③ The operating current and operating time of overcurrent relay.

④ Automatic testing of the pull in voltage, release voltage, action time, coil resistance, and contact resistance of electromagnetic contactors.

⑤ It has the function of calculating contact power consumption and coil power consumption.

⑥ It has the function of relay aging test.

⑦ Equipped with insulation resistance and withstand voltage test

The device has intelligent control functions and comprehensive protection measures.

Relay test benchEquipped with S232 and 485 interfaces, it can control and communicate with the upper computer.

The relay comprehensive test bench is operated through a 15.6-inch touch screen
