High-voltage circuit breaker

Abstract

The invention discloses a high-voltage circuit breaker, which comprises an operating system control box, a first protection housing, a second protection housing, a current transformer and a ceramic support column. The surface of the operating system control box is provided with an observation window. One side of a second metal installation flange is provided with the current transformer through a bolt. The surface of a conductive wiring column is provided with a second insulation umbrella skirt. The surface of an insulation housing is provided with a first insulation umbrella skirt. The insulation housing is internally provided with the ceramic support column. The outer side of the insulation housing is equipped with the first protection housing and the second protection housing through a fastening bolt and a fastening nut. The two ends of the second protection housing and the two ends of the first protection housing are respectively provided with a first installation component and a second installation component, which are mutually cooperated. The high-voltage circuit breaker has the advantages of being convenient to operate and high in safety and the like through a series of structures.

Description

technical field [0001] The invention relates to the technical field of circuit breakers, in particular to a high-voltage circuit breaker. Background technique [0002] A high-voltage circuit breaker or high-voltage switch is one of many circuit breakers. It can not only cut off or close the no-load current and load current in the high-voltage circuit, but also cut off the overload through the function of the relay protection device when the system fails. Current and short-circuit current, it has a fairly complete arc extinguishing structure and sufficient current breaking capacity, and can be divided into: oil circuit breaker (more oil circuit breaker, less oil circuit breaker), sulfur hexafluoride circuit breaker (SF6 circuit breaker) , Compressed air circuit breakers, vacuum circuit breakers, etc. [0003] However, most of the common high-voltage circuit breakers on the market are single-structure high-voltage circuit breakers with relatively simple functions, which often...

Problems solved by technology

[0003] However, most of the common high-voltage circuit breakers on the market are single-structure high-voltage circuit breakers with relatively simple functions, which often cause many inconveniences in actual use. For example, traditional high-voltage circuit breakers do not Easy to install, it is very troublesome in the process of assembly, resulting in long installation time; traditional high-voltage circuit breakers do not have self-protection functions, so traditional high-voltage circuit breakers often cause damage to high-voltage circuit breakers in collisions and other situations during use , so that the use of high-voltage circuit breakers is affected, and unnecessary circuit breakdowns occur, so this prompts the birth of a high-voltage circuit breaker with self-protection function and high safety performance.
