Description

Technical Field

[0001] The utility model relates to the technical field of starters, in particular to a starter with a wireless leakage test function in coal mines. Background Art

[0002] Article 451 of the 2016 version of the Coal Mine Safety Regulations: High-voltage control equipment for underground high-voltage motors and power transformers shall have short-circuit, overload, grounding and undervoltage release protection. The feeder lines from the mining area substation, mobile substation or distribution point underground must have short-circuit, overload and leakage protection. The control equipment for low-voltage motors must have short-circuit, overload, single-phase line break, leakage lockout protection and remote control functions.

[0003] The low-voltage motor control equipment currently on the market, such as starters (soft starters) and frequency converters, only have the motor starting function, and do not have the remote leakage test function for the feeder switch. It is necessary to connect the load side of the starter to the test resistor, one end of the test resistor is connected to the screw buckle of the fuse tube, and the other end is connected to the outer shell. After the outer cover is covered, power is supplied to observe whether the feeder switch / mobile transformer trips. If it trips, it means that the leakage detection protection device is operating reliably. After the test is completed, the test resistor must be removed. The test cost is high and the practicality is low, so it is urgent to design a starter with a wireless leakage test function in coal mines. Utility Model Content

[0007] As a further technical solution of the utility model, the leakage test button, the leakage test board, the remote control receiving module, the optical fiber communication plate and the starter body are electrically connected through wires.
