法國施耐德中壓真空斷路器維護事項
“真空斷路器”因其滅弧介質和滅弧后觸頭間隙的絕緣介質都是高真空而得名；
其具有體積小、重量輕、適用于頻繁操作、滅弧不用檢修的優(yōu)點，
在配電網中應用較為普及。 真空斷路器是3～10kV，
50Hz三相交流系統(tǒng)中的戶內配電裝置，
可供工礦企業(yè)、發(fā)電廠、變電站中作為電器設備的保護和控制之用，
"Vacuum circuit breaker" because of its arc extinguishing media and
the contact between the arc after the insulating medium are high vacuum named;
It has a small size, light weight, suitable for frequent operation, arc off without the advantages of maintenance,
In the distribution network application is more popular. Vacuum circuit breaker is 3 ~ 10kV,
下表是選用參數的列項說明，并以三種真空斷路器數據為例。
表中所列各項參數，均須按JB3855和DL403標準的要求，
在產品的型式試驗中逐項加以驗證，zui終數據以型式試驗報告為準。

主要結構
真空斷路器主要包含三大部分：真空滅弧室、電磁或彈簧操動機構、支架及其
For industrial and mining enterprises, power plants, substations as electrical equipment protection and control purposes,
Especially for the requirements of non-oil, less maintenance and frequent use of the use of places,
Circuit breakers can be configured in the central cabinet, double cabinet,
fixed cabinet as a control and protection of high voltage electrical equipment.
Vacuum circuit breaker main technical parameters Vacuum circuit breaker parameters, c
an be divided into the optional parameters and operating parameters of two aspects.
The former for the user to select the use of design; the latter is the circuit breaker itself,
 mechanical characteristics or movement characteristics, for the operation, adjust the technical indicators
特別適用于要求無油化、少檢修及頻繁操作的使用場所，
