          適用范圍Application Range

          適用于三相交流50Hz、額定電壓為12kV電力系統的戶內開關設備,作為工廠企業、發電廠及變電站電氣設施的控制和保護單元。

          It is applicable to indoor switchgear of three phases AC 50Hz, rated voltage of 12KV power system, as the control and protection unit of factory enterprise, power plant and substation electric utility.

          產品特點Product Features

          真空斷路器總體結構采用操動機構和滅弧室前后一字排開布置的形式,隔離開關、接地開關與斷路器集成一體,與FT8負荷開關的外形與尺寸完全相同。開關為一體化側裝式結構設計,其包括安裝機架、支撐絕緣筒、負荷開關、隔離開關、接地開關及操動機構。

          1.小型化:寬度、高度尺寸小,可實現柜體寬度500mm,電纜接線高度≥650mm;

          2.一體化:負荷開關(斷路器)、隔離開關、接地開關一體式設計,開關可以倒裝;

          3.隔離開關分閘狀態時,隔離刀對地距離扔大于125mm;

          4.開關裝在柜內后仍可進行機械特性測試;

          5.完善的“五防”聯鎖裝置、具有手動和電動兩用操作功能。

          The overall structure of the vacuum circuit breaker adopts the form of operation mechanism and arc-extinguishing chamber arranged one line before and after. The disconnector, fhe earthing switch and the circuit breaker are integrated to one unit, which has the same appearance and dimensions of FT8 load switch. The switch is designed to integrated side-installed structure, which includes installed frame, supporting insulating cylinder, load switch, disconnector, earthing switch and operation mechanism.

          1. Miniaturization: Smaller width and height, which may realize the switchgear width of 500mm, the cable wiring height is not less than 650mm;

          2. Integration: The integration design of the load switch, the disconnector, the earthing switch and fuse, the switch may he inverted to installed;

          3. When the disconnector is in the state of open, the distance between isolating knife to earthing is still more than 125mm;

          4. The switch may also be tested of mechanical characteristic after it is installed in the switchgear;

          5. Perfect “five prevention” interlocking device, which has two operation functions of manual and motor.
