供应SF6户外柱上负荷高压开关(带隔离）

1、该负荷开关是以SF6气体作为绝缘和灭弧介质，将触头系统、操作系统和电流互感器全部密封在一个不锈钢箱体内，具有较高技术含量的新型高压开关设备。

this switch leads the new technology, which adopt the gas of SF6 as the insulator and the are estinguishing medium. the contact, system, three current transformer and six potential transformer are all sealed in a stainless steel case.

2、采用压气式灭弧原理，触头系统采用铜钨合金，具有较高的电寿命。

Adopt the principle of compressing air for are extinguishing. the contact system adopt coppertungesten alloy, it has long life lrelectricity.

3、操动机构采用双凸轮弹簧机构，其结构简单，性能可靠，具有较高的分合速出线套与开关本体之间、操作机构手柄与机构本体之间，采用EPR系列特殊的橡胶密封材料制作，并能过了-80℃的测试。

the operation mechanism is a spring mechanism with duble cam, simple coustrue, high reliability, and lead a high speed when open or close. whatever between ortgoing and the wsitch or between operating mechanism handle and mechanism, all adopt sealant to seal it, which produced by a special rubber called EPR series and passed the test under the temperature of -80℃.

4、可选配电压传感器，以采集配电网运行参数。

using inside current and potential transformer to collect the data from the network.

5、本体采用3mm以上不锈钢板，采用熔接氩弧焊接，并进行了防锈处理。

the body of this load switch all manufaotured by the stainless steel that the thickness exceed 3mm, skillful welding, and by rust prevention treatment.

6、吸湿剂可把本体内部的湿度保持在300PPm以下，提高了整体的防泄防凝露性，可免维护30年。

by the effect of the desiccant inside, it could keep the internal humidity under 300PPm. it improved the ability of anti-leakageand condensation. free of maintenance for 30 years.
