Description

Vacuum circuit breaker for outdoor high-salt-fog environment Technical Field The utility model relates to a circuit breaker, in particular to a vacuum circuit breaker for an outdoor high-salt-fog environment. Background The ZW17-40.5 series outdoor high-voltage vacuum circuit breaker is a three-phase alternating current 50Hz outdoor high-voltage switch device, a user-exterior vacuum arc-extinguishing chamber is selected, a novel insulating material is adopted, and the ZW17-40.5 series outdoor high-voltage vacuum circuit breaker is suitable for a power transmission and transformation system to be used for switching load current, overload current and short-circuit current, and has the advantages of safety, reliability, long service life and the like. However, with the rapid development of economy, the requirements of users on power supply reliability and power supply quality are increasingly improved. In the southeast coastal areas with higher air humidity and higher salt content, the air belongs to a high-salt-fog and high-humidity medium, so that serious salt pollution is easily caused to high-voltage circuit breaker components, intermittent spark discharge and insulation aging are caused to the surface of the product, and large-area power failure is caused. Therefore, an effective and feasible scheme is required to thoroughly solve the insulation problem of the vacuum high-voltage circuit breaker in the salt spray environment. Disclosure of utility model The utility model provides a vacuum circuit breaker for an outdoor high-salt-fog environment in order to make up for the defects of the prior art. The utility model is realized by the following technical scheme: The vacuum circuit breaker for the outdoor high-salt-fog environment comprises a support, wherein a frame is arranged on the support, three groups of porcelain sleeves are arranged above the frame, an operation box is connected below the frame, and a CT19 spring operation mechanism is arranged in the operation box. And the upper end surface and the lower end surface of the outer side of the upper outgoing line terminal are respectively provided with a tin lining layer. The outer side of the lower outlet terminal the lower end surfaces are respectively provided with silver plating layers. And a secondary wiring terminal is arranged in the operation box. The utility model has the beneficial effects that the corrosion insulation problem of the circuit breaker in high-salt fog and high-humidity environment of offshore wind power and the like which mainly use new energy sources such as wind power, photovoltaic and the like can be effectively, reliably and thoroughly solved.
