Automatic running-in system and method for power transmission grade high-voltage vacuum circuit breaker

Abstract

The invention relates to an automatic running-in system and method for a power transmission grade high-voltage vacuum circuit breaker. The system comprises a power transmission grade high-voltage vacuum circuit breaker, a skid, a running-in test station module, a secondary connector, a hydraulic jacking system, a running-in control system and a sound insulation running-in room. The power transmission grade high-voltage vacuum circuit breaker is installed on a technological column of the skid. The running-in test station module is installed on the ground in the sound insulation running-in room. The sound insulation running-in room is provided with a sound insulation automatic door at a position corresponding to the inlet and outlet end of the running-in test station module. The sound insulation automatic door is linked with the skid; the hydraulic jacking system is mounted in the sound insulation running-in room; and the running-in control system is installed in the sound insulation running-in room. According to the invention, the running-in test operation efficiency of the power transmission grade high-voltage vacuum circuit breaker can be improved, and the personal safety during the test operation is ensured.

Description

Technical field [0001] The present invention relates to the field of high-pressure electrical test devices, and more particularly to automatic engagement systems and methods of transmission grade high pressure vacuum circuit breakers. Background technique [0002] 126kV and above Transmission level high-voltage circuit breakers are the most important control and protection equipment in power transmission, and now the SF6 circuit breaker is dominated. However, SF6 is the strongest greenhouse effector recognized by the Kyoto Protocol, and its greenhouse effect coefficient is 23900 times of CO2. The international conventions such as the "Paris Agreement" have been issued in the world to limit the use of the gas. Therefore, the reduction in SF6 gas and the replacement of the power equipment industry need to solve, and even disabled SF6 circuit breakers has been irreversible. Therefore, 126KV and above transmission level high-voltage vacuum circuit breakers will grow rapidly in the fu...

Problems solved by technology

[0003] Due to the high rated voltage of the transmission level high-voltage vacuum circuit breaker, its heavy weight, large volume, and high height make it difficult to move. During the running-in test, the circuit breaker body vibrates greatly and the opening and closing operation noise is large. The current leading method is: try After the product is assembled and debugged in a fixed working position, it still stays in this position, and the testers use night or rest days to conduct running-in tests on it

This test operation method has the following disadvantages: the product running-in test cannot be carried out during normal working hours, because the circuit breaker running-in test needs to perform opening and closing and energy storage operations for many times, and the noise is particularly loud, which will cause harm to personnel working normally in the area. Great impact, so the current dominant method has problems such as high noise, run-in test and other operations can only be performed in series, and the efficiency of production test is not high
