Vacuum arc extinguishing chamber: This is the core component of a vacuum circuit breaker, mainly responsible for arc extinguishing and insulation. The vacuum arc extinguishing chamber is composed of an airtight insulation shell, a conductive system, a shielding system, etc. The airtight insulation shell is usually made of ceramic, glass or microcrystalline glass. The conductive system includes fixed conductive rods, moving contacts, etc. The shielding system is used to prevent arc products from splashing, improve electric field distribution, and absorb arc energy.
Operating mechanism: The operating mechanism is responsible for controlling the opening and closing operation of the vacuum circuit breaker. Common operating mechanisms include spring operated mechanisms, permanent magnet operated mechanisms, etc. The operating mechanism operates the vacuum circuit breaker through components such as opening and closing electromagnets and brackets.
Supporting components: including chassis vehicles, insulation brackets, insulators, etc., used to support and fix various components of vacuum circuit breakers to ensure their stable operation.
Other components, such as the base and transmission part, together form the complete structure of the vacuum circuit breaker to ensure its normal operation.
