西安FZW32-12高压真空负荷开关
- 概述General
FZW32-12/T630-20型户外高压隔离真空负荷开关是由我公司和西安高压电器研究所联合研制、开发，并由我公司生产的新一代高压电器产品，经严格的型式试验和试运行考核，各项技术性能指示全部达到GB3804和IE标准，适用于额定电压12KV、额定电流630A、三相交流50Hz的供电网络中。
FZW32-12/T630-20 type outdoor high voltage isolate vacuum load switch was researched and developed by our company and Xi’an high voltage electrical appliance research laboratory. Then our company is the first manufacture new high voltage electrical appliance products. Through series testing and long time running examine, each technical indication all have reached GB3804 and IE standard, So it is used in rated high voltage 12KV, rated 630A and 3-phase AC 50Hz electrical supply net.

- 工作原理Working elements
负荷开关是由隔离刀和真空灭弧室这两大组件组成，隔离刀承担了合闸和分闸时绝缘作用，真空灭弧室承担熄灭电弧的作用。
隔离刀是由弹簧过中机构进行合分闸操作的，过中弹簧提供了隔离刀合闸时所需的能量，并保证了真空灭弧室在分闸时熄灭电弧而不受人为因素的影响，真空灭弧室在隔离刀的分闸过程中，有快速机构提供灭弧室的分闸速度。隔离刀的三相联动操作确保了灭弧室的分闸同期性。
The load switch is composed by isolating knife and vacuum arc suppression, the isolating knife is taking on the insulator function when switch on and off, and the vacuum arc suppression is taking on crush out arc suppression function.
Isolating knife switch on and off operating by spring system, And the spring system provide the power that was needed by isolating knife switch on and off, make sure the crush out arc suppression is not effected by human fact when the vacuum arc suppression is switch off. There is a speed system was provide the speed of switch off of the explosion chamber when the vacuum explosion chamber in proceeding of the isolating knife switch off. The 3-phase linkage is making sure the explosion chamber switch off in synchronicity.
