High-voltage circuit breaker

Abstract

The invention relates to a high-voltage circuit breaker which comprises a mechanism box, a solid-sealed polar pole, a current transformer and an inrush current controller, wherein the solid-sealed polar pole, the current transformer and the inrush current controller are fixed on the mechanism box, a driving mechanism used for driving the solid-sealed polar pole to be switched on and switched off is arranged in the mechanism box, and the inrush current controller is in control connection with the driving mechanism. The high-voltage circuit breaker further comprises an adapter fixed on the mechanism box, part of contacts of the adapter are mutual inductor contacts in conductive connection with the current transformer, the other part of contacts of the adapter are controller contacts in conductive connection with the inrush current controller, and the mutual inductor contacts and the controller contacts are in one-to-one correspondence. The high-voltage circuit breaker further comprises connecting conductors which are detachably connected with the corresponding mutual inductor contacts and the controller contacts so as to achieve conductive communication of the corresponding mutual inductor contacts and the controller contacts, and by means of the scheme, the high-voltage circuit breaker can be put in and put out simply and easily and can be put in and put out without depending on professional after-sales personnel.

Description

technical field [0001] The invention relates to a high voltage circuit breaker. Background technique [0002] High-voltage circuit breaker is an important primary device in the power system, which plays the role of on-off and protection in the power system. In specific use, high-voltage circuit breakers are used in conjunction with secondary equipment. [0003] Since the primary equipment and the secondary equipment are mostly bid separately, it often happens that the primary equipment has been installed but the secondary equipment has not yet entered the site, and the primary equipment needs to be debugged with a protection mechanism after installation. In this case, the most common, common, and economical method in the actual operation process is to install an inrush controller inside the high-voltage circuit breaker. The controller replaces the secondary equipment to enable the high-voltage circuit breaker to realize the inrush protection function. When the secondary e...
