    產品結構

    Product Structure

    柜體分隔成母線室和開關室。柜體為組裝式結構,穩固可靠。

    具有獨特的活門結構,防護性能好。負荷開關分閘后,活門自動將斷口隔離,使進線,母線室與開關室分隔,檢修、維護安全可靠。延伸組合方便,可構成環網供電單元及各種接線方式《參見主結線典型方案圖)。三相采用前后排列,柜體寬度尺寸小,占地面積少。采用壓氣式原理滅弧,開斷性能穩定可靠。操動機構有手動和電動兩種選擇。機械聯鎖先進可靠,滿足”五防”要求。負荷開關及接地刀均可用鎖鎖定在開或合的位置上,并可按程序實現負荷開關之間的聯鎖。主元件負荷開關、熔斷器更換方便。

    無環境污染,不會發生火災及爆炸危險。

    可帶分勵脫扣器??杉友b帶電顯示裝置和核相裝置。


    The cabinet body is separated into bus room and switch room. The cabinet body is of assembly structure, which is stable and reliable.


    It has a unique valve structure and good protective property. After the break-brake of load switch, the valve will automatically isolate the fracture to separate the incoming line and bus room with the switch room, the overhauling and maintenance is safe and reliable. It is convenient to extend the combination, and the ring net power supply unit and a variety of wiring methods (see the typical program diagram of main wiring) can be constituted. Three-phase adopts tandem arrangement with small size of the width of the cabinet body and small   occupied area. It adopts compressed gas principle for arc extinguishing, and the switching on and switching off performance is stable and reliable. Operating mechanism has two options of manual and motor-driven operation. Advanced and reliable mechanical interlock meets the requirements of “five prevention”. Load switch and ground switch can be locked at open or closed position with a lock, and the interlocking between load switches can be achieved in accordance with the program. It is convenient to replace the load switch of main component and fuse.


    There are no environmental pollution, nor fire and explosion hazards.


    Shunt trip can be equipped, and live display device and nuclear phase device can be additionally installed.
