Abstract

The invention relates to a simulation rainfall test device used for an electric device. The test device comprises a water tank, a water transmission member and water spraying mechanisms, which are successively arranged. The water transmission member comprises a water pump and a buffering assembly. The water pump is connected with the water tank and parallel-connected water spraying branches. The buffering assembly is arranged between the water pump and the buffering assembly. Each of the water spraying members comprises a valve and a nozzle movably connected with a corresponding branch. According to the invention, it is ensured that a high-voltage electric device can get wet in the simulation rain satisfying requirements during an electric test in a rainfall state and reliability of the device in a natural rainfall condition is verified.

Description

technical field [0001] The invention relates to a detection device, in particular to a simulated rain test device for electrical equipment. Background technique [0002] Verifying the working characteristics of electrical equipment in a rainy environment is an essential part of the electrical equipment test process. Therefore, there is a need for a simulated rain test device for electrical equipment to conduct insulation property tests on electrical equipment in a rainy environment. [0003] The existing spraying simulated rain test device has the following disadvantages: ①The spraying distance is too short to meet the spraying distance requirements for large electrical equipment. ② The spraying is not uniform, and it is impossible to ensure that the amount of rain on the electrical equipment is even. ③The amount of rain cannot be adjusted, and it is impossible to accurately simulate the waterproof ability of electrical equipment under heavy rain. ④ The ability to recycle...
