Abstract

The invention belongs to the technical field of low-voltage apparatus tests, and particularly relates to a mining disconnecting switch breaking test device and test method. An executive component of a pneumatic mechanism is connected to a rotating cylinder; one end of the rotating cylinder is connected to a main shaft, and the other end of the rotating cylinder is connected to a manual operating rod; the other end of the main shaft is connected to one end of a connector, and the other end of the connector is connected to a drive shaft of a disconnecting switch; the drive shaft of the disconnecting switch is connected to the disconnecting switch; the pneumatic mechanism is connected to a hydraulic mechanism by a mechanical connection component; the hydraulic mechanism is fixed to a chassis; two ends of the chassis are connected to the bottoms of side walls, and a workbench is connected to one side wall. According to the invention, the pneumatic mechanism can directly drive the disconnecting switch to act, and the hydraulic mechanism can adjust the vertical height of the test device; the mining disconnecting switch breaking test device has the advantages of simple structure, easy operation, high reliability, and good stability; and meanwhile, the test device acts by remote control, so that the potential risk due to manual operation during a test process can be avoided.

Description

technical field [0001] The invention belongs to the technical field of low-voltage electrical appliance testing, and in particular relates to a disconnecting test device and a testing method for a mine-used isolating switch. Background technique [0002] Isolating switches are the main components of mining equipment such as soft starters, frequency converters, and feed switches, and have broad application prospects in the field of coal mines. The isolation switch plays the role of voltage isolation in the equipment, and its performance is directly related to the safe operation of the coal mine power system. At present, the main problem in the detection and inspection of mining disconnectors and related products is that the breaking needs to rely on manual operation, which has poor reliability and controllability, and it is difficult to simulate the actual breaking situation of the disconnector. Contents of the invention [0003] Aiming at the problems existing in the abov...
