法国施耐德中压真空断路器维护事项
“真空断路器”因其灭弧介质和灭弧后触头间隙的绝缘介质都是高真空而得名；
其具有体积小、重量轻、适用于频繁操作、灭弧不用检修的优点，
在配电网中应用较为普及。 真空断路器是3～10kV，
50Hz三相交流系统中的户内配电装置，
可供工矿企业、发电厂、变电站中作为电器设备的保护和控制之用，
"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,
下表是选用参数的列项说明，并以三种真空断路器数据为例。
表中所列各项参数，均须按JB3855和DL403标准的要求，
在产品的型式试验中逐项加以验证，zui终数据以型式试验报告为准。

主要结构
真空断路器主要包含三大部分：真空灭弧室、电磁或弹簧操动机构、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
特别适用于要求无油化、少检修及频繁操作的使用场所，
