Problems solved by technology

[0002] The circuit breaker is usually equipped with a voltage transformer structure. The existing connection method is mainly to directly connect the voltage transformer to the circuit breaker shell with bolts. When the external force acts, the voltage transformer is easily affected, which is very easy. damage, and, since the circuit breaker is usually installed with an iron core, its sealing performance is high, and now the common rubber seal structure is easy to age after long-term use

Embodiment 1

[0023] Such as figure 1 As shown, a circuit breaker includes a circuit breaker housing 101 and an insulated electrode column 102 arranged above the circuit breaker housing 101, and a voltage transformer housing is provided on one side of the circuit breaker housing 101 103, the voltage transformer housing 103 is provided with a voltage transformer 104, a through groove is provided on the side wall of the circuit breaker housing 101, and a positioning plate 105 is provided on the inner wall of the passage groove, The positioning plate 105 is perpendicular to the side wall of the circuit breaker housing 101, and the lower end of the voltage transformer housing 103 is provided with a fixed frame 106, and the fixed frame 106 is plugged into the channel. Inside the groove, an L-shaped baffle 107 is provided at the end of the fixed frame 106 close to the voltage transformer housing 103, and a card slot 108 is formed between the baffle 107 and the fixed frame 106. A sealing plate 10...

Embodiment 2

[0026] In this embodiment, in order to facilitate the installation and fixing of the overall structure, preferably, an intermediate beam is welded at the lower end of the circuit breaker housing 101, and housing brackets 113 are respectively arranged on both sides of the intermediate beam. The housing bracket 113 is detachably connected to the support beam 119 .

[0027] Further preferably, this embodiment discloses a preferred structure of the intermediate beam, the intermediate beam is formed by the intermediate plate 115 and the bottom plate 116 below the intermediate plate 115 to form an inverted T-shaped structure, the intermediate plate The upper end of 115 is fixedly connected to the lower end surface of the circuit breaker housing 101 , and the housing brackets 113 are respectively detachably connected under the bottom plate 116 .

[0028] In this embodiment, in order to improve the stability of the structure, preferably, the housing bracket 113 has a U-shaped structur...

Embodiment 3

[0033] In this embodiment, on the basis of Embodiment 1, in order to improve the sealing performance of the positioning plate relative to the fixed frame, in this embodiment, preferably, on the end surface of the positioning plate 105 facing the fixed frame 106, a The protruding structure 120 , the protruding structure 120 and the sealing part 110 are staggered from each other. The inclined surface of the raised structure is attached to the inclined surface of the sealing part. Since both the positioning plate and the sealing part are made of brass, metal sealing can be realized after installation, and the sealing effect can be effectively improved.

[0034] In order for the gasket to have good sealing properties and relative elasticity, in this embodiment, preferably, the gasket 111 is a hollow ring structure.

Abstract

The invention discloses a circuit breaker. The circuit breaker comprises a circuit breaker housing and insulated electrode columns arranged on the circuit breaker housing. A voltage transformer housing is arranged at one side of the circuit breaker housing, a voltage transformer is disposed on the voltage transformer housing, a through groove is disposed at the side wall of the circuit breaker housing, a positioning plate is disposed at the inner wall of the through groove, the positioning plate is perpendicular to the side wall of the circuit breaker housing, a fixed frame is disposed at the lower end of the voltage transformer housing, the fixed frame is inserted into the inner side of the through groove, one end, which is close to the voltage transformer housing, of the fixed frame is provided with an L-shaped baffle plate, and a clamping groove is formed between the baffle plate and the fixed frame. The circuit breaker is advantageous in that, by pressing a sealing part structure onto the positioning plate, rigid metal sealing is achieved, connection efficiency is improved, and good sealing performance is provided.

Description

technical field [0001] The invention relates to a circuit breaker. Background technique [0002] The circuit breaker is usually equipped with a voltage transformer structure. The existing connection method is mainly to directly connect the voltage transformer to the circuit breaker shell with bolts. When the external force acts, the voltage transformer is easily affected, which is very easy. In addition, because the circuit breaker is usually equipped with an iron core, its sealing performance is high, and now the common rubber seal structure is easy to age after long-term use. Contents of the invention [0003] The purpose of the present invention is to provide a circuit breaker, which can improve the problems existing in the prior art. By adopting the sealing part structure and pressing it on the positioning plate, a rigid metal seal can be realized, which can improve the connection efficiency and have good sealing performance. . [0004] The present invention is reali...
