Abstract

The present invention relates to a mechanical linkage circuit breaker, comprising a crossbeam and a pull rod, wherein the pull rod is disposed in the crossbeam. The mechanical linkage circuit breaker also comprises a guiding means. The guiding means comprises two load-bearing elements and two guide sleeves, wherein the load-bearing elements are fixed to the crossbeam and located on two sides of the pull rod. The guide sleeves surround the load-bearing elements, respectively, in a rotatable fashion and are spaced apart from the pull rod. Such a mechanical linkage circuit breaker has high reliability and stability.

Description

technical field [0001] The invention relates to a mechanical linkage circuit breaker, in particular to a three-phase mechanical linkage high-voltage circuit breaker with a guide device. Background technique [0002] The circuit breaker is an important switching device in the power system, which is responsible for the dual tasks of control and protection. Its performance is one of the important factors that determine whether the power system can operate safely. With the improvement of people's requirements for power supply quality, the requirements for the reliability and stability of circuit breakers are also getting higher and higher. Especially for mechanical linkage circuit breakers, its operating mechanism is an important part of mechanical linkage circuit breakers, and is one of the key components that determine the opening and closing performance of mechanical linkage circuit breakers. Its performance is directly related to the performance of mechanical linkage circuit...
