Problems solved by technology

[0003] The use of double-break and multi-break forms is one of the main methods at present, but the transmission mechanism of the existing multi-break circuit breaker is complex, the synchronization of breaking between multiple breaks cannot be guaranteed, and the opening speed is not high. The arc time is longer, resulting in untimely breaking or even breaking failure, resulting in serious accidents, and the gains outweigh the gains

Embodiment Construction

[0038]Hereinafter, the technical solutions of the present invention will be described in detail by way of embodiments with reference to the accompanying drawings. It should be noted here that the descriptions of these embodiments are used to help the understanding of the present invention, but do not constitute a limitation of the present invention.

[0039] The term "and / or" in this article is only an association relationship to describe associated objects, indicating that there can be three kinds of relationships, for example, A and / or B, which can mean: A alone exists, B alone exists, and A and B exist simultaneously. There are three cases of B. In this article, the term " / and" is to describe another related object relationship, which means that there can be two relationships, for example, A / and B, which can mean that A exists alone, and A and B exist alone. , In addition, the character " / " in this text generally indicates that the related objects are an "or" relationship....

Abstract

The invention discloses a complete set of circuit breaker for fast closing and opening, which comprises: a casing, which is generally box-shaped; a power transmission part, which is arranged on the casing, and the power transmission part includes a power part and a transmission part, The power part is arranged on the casing, and the transmission part is arranged on the power part; the power part includes a transmission rod, a motor and a manual control part, both the transmission rod and the motor are arranged on the housing, and the manual control part is arranged on the transmission rod. The connection and disconnection part is arranged on the casing, the connection and disconnection part includes a terminal, a connecting rod and a connecting piece, the connecting post and the connecting rod are both arranged on the casing, and the connecting part is arranged on the transmission part ; The power part controls the disconnection part through the transmission part to realize the opening and closing of the circuit breaker. The invention has the advantages of simple structure, reasonable structure design, reliable operation, safe use, high arc extinguishing efficiency, and can quickly complete opening.

Description

technical field [0001] The present invention relates to the technical field of electric power systems, and more particularly, to a complete set of circuit breakers for quick closing and opening. Background technique [0002] With the rapid development and improvement of the national grid construction, the power system has higher and higher requirements for the reliability and stability of switchgear. The traditional high-voltage AC double-break SF6 circuit breaker with a voltage level of 363kV and above can no longer meet the needs of power grid development. Therefore, it is necessary to optimize the design of the entire electric field of the arc extinguishing chamber of the existing circuit breaker to make the overall electric field of the arc extinguishing chamber more efficient. uniform, the structure design is more reasonable, the overall technical indicators of the product are higher, and the operation will be more reliable. Through the technical improvement of the pat...
