The safe operation of power distribution equipment is crucial to the stability of the power grid, the operating conditions of the distribution network equipment on the distribution network equipment detection test efficiency put forward higher requirements, the current traditional detection methods flow of cumbersome procedures, manpower, and material costs, has been unable to meet the requirements of the distribution network equipment testing. Therefore, this paper considered the distribution network equipment temperature rise test in the load test, no-load test, and other specific test types, and designed an intelligent switching device, which could be applied to different tests of distribution equipment.
