1  用途 Application

       氣動單極隔離開關，用于無電壓無負荷的情況下接通和轉換線路。

       Pneumatic controlled single pole isolated switch is used to switch on and convert circuit under

       the condition of no voltage and loads.

2  安裝運行地區(qū)的環(huán)境條件 The condition of installing and operating environment

2.1  安裝運行地區(qū)及周圍不應有腐蝕性的氣體或蒸汽，無電導性或爆炸性塵埃。

     Neither corrosive gas such as acid gas, alkali gas nor steam is allowed in the ambient air.

     No blast or inflammable peril is allowed.

2.2  安裝場所無劇烈機械震動。

     No acutely vibration, jol is allowed.

2.3  海拔高度：不超過1000米。

     Altitude of installation place is not more than 1 km.

2.4  環(huán)境空氣溫度：戶內 -25（-40）～+50℃。

     Ambient air temperature range is -25（-40）～+50℃ indoor.

2.5  空氣的相對濕度不高于90％。

     The relative humidity of the air is not more than 90%.

2.6  適用頻率:  50～200 Hz。

     Application of frequency is 50～200 Hz.

  3  氣動單極隔離開關結構簡介  Brief introduction

  3.1  開關的絕緣支柱全部采用大爬距的瓷質支柱，12kV電壓的產品其絕緣支柱采用環(huán)氧樹脂壓鑄型。絕

   緣拉桿采用帶硅橡膠傘群的環(huán)氧布棒。

        Insulators of switch all used porcelain surrport which has large creep distance, 12kV voltage grade using epoxy resin pressure casting. The insulating pull rod is used  epoxy rod with a silicon rubber umbrella group.

   3.2  U型觸板、導電桿和接線端子全部采用型材制造，并進行表面處理。其接觸方式為線接觸，它能保證接觸

   良好、減小操作力和提高轉動的靈活性。

        U type touch panel, a conductive rod and and all terminals are used section bar manufacturing,

   and it's surface treated. The contact's mode is line, it can ensure the contact good, reduces the operating force and increase the rotation flexibility.

   3.3  氣缸采用無需潤滑的國產優(yōu)質氣缸，免去用戶在使用時需要定期在油霧器中注入潤滑油。

        The cylinder without lubrication has high-quality, and  is not required to use regularly in the oil mist into the lubricating oil.

  4  氣動單極隔離開關工作原理

      The working principle of single pole pneumatic isolated switch

      氣動單極隔離開關根據(jù)不同的電壓及電流的大小，配用不同的氣缸來進行操作，使之達到分、合閘

   的目的。氣缸上均配有調速接頭，可調整開關的分、合閘速度，在調速接頭上有連接氣路管子的連接頭，只要

   將相應直徑的管子插入即可。

        Each switch depending on the voltage and current level with different cylinder drive, so as to achieve the points, closing the purpose. Cylinder equipped with speed control connector is used to adjust the switching points, closing speed in the speed connector equipped air pipe connector, as long as the corresponding diameter of the tube can be inserted.
