Abstract

The invention provides a high-voltage circuit breaker dynamic contact resistance testing device capable of improving stability, which comprises a shell. A rotor is rotatably connected to the bottom of an inner cavity of the shell, a cooling mechanism is movably connected to the inner cavity of the shell, and the cooling mechanism comprises a circulating flow pipe. The bottom of an inner cavity of the circulating flow pipe is rotationally connected with a transmission gear. According to the high-voltage circuit breaker dynamic contact resistance testing device capable of improving the stability, a brush head is automatically isolated from the interior of the testing device when a vortex tube rotates, a targeted rapid cooling mechanism is performed, an electrostatic sleeve is synchronously matched to operate at an inlet of a circulating flow tube to suck and remove impurities, and when heat dissipation is finished, the guide frame and the telescopic clamping plate are used for scraping impurities at the end of the electrostatic sleeve, and the cleaning box is used for collecting the impurities, so that the stability performance of the test is effectively improved, and adverse factors influencing the stability of the equipment test are further eliminated.

Description

technical field [0001] The invention relates to the technical field of resistance testing, in particular to a dynamic contact resistance testing device for a high-voltage circuit breaker with improved stability. Background technique [0002] At present, when testing the dynamic contact resistance of high-voltage circuit breakers, the rotor needs to rotate continuously relative to the stator, and the stator relies on the brush head to maintain dynamic contact with the rotor to conduct circuit conduction, but after a single test, the brush The temperature at the head will rise sharply. When more tests are required, if the temperature of the brush head is not cooled in time, it will have the risk of being burned and damaged, and it will also affect the adjacent components, making the equipment test difficult. The stability performance is reduced, and the general test device uses fans to cool down its interior. However, due to the interlaced and complex layout of the internal co...
