Abstract

The invention provides an online detection device for the vacuum degree of a vacuum breaker. The online detection device comprises a first temperature sensor, a second temperature sensor, a control module and a monitoring device, which are connected via a signal, wherein the first temperature sensor is arranged in an electric conductor in a vacuum arc-extinguishing chamber; and the second temperature sensor is arranged outside the vacuum arc-extinguishing chamber. The invention further provides an online detection method for the vacuum degree of the vacuum breaker. The online detection method for the vacuum degree of the vacuum breaker and the online detection device provided by the invention can solve the problem of online detection of the vacuum arc-extinguishing chamber by detecting the temperature change of the electric conductor. The method is suitable for online qualitative detection of the vacuum arc-extinguishing chamber of the breaker, can achieve real-time online detection on the vacuum degree of the vacuum arc-extinguishing chamber and improve the power supply reliability.

Description

technical field [0001] The invention relates to the technical field of vacuum circuit breaker detection, in particular to a method for online detection of vacuum degree of a vacuum circuit breaker and a detection device thereof. Background technique [0002] Vacuum circuit breaker is a very promising power breaking device in the field of low voltage and medium voltage. It is a switching device with vacuum as the insulation and arc extinguishing medium. The gas molecules in the vacuum are extremely rare, and there are very few chances of electrons colliding with molecules, so the insulation strength of the vacuum circuit breaker is very high. Compared with other types of circuit breakers, vacuum circuit breakers have the advantages of safety, reliability, long life, small maintenance workload, and no pollution to the environment. [0003] The vacuum interrupter is the core part of the vacuum circuit breaker. In order to achieve current breaking and arc extinguishing, the pr...
