气动隔离开关

1  用途 Application

       气动单极隔离开关,用于无电压无负荷的情况下接通和转换线路。

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

       the condition of no voltage and loads.


2  安装运行地区的环境条件 The condition of installing and operating environment

2.1  安装运行地区及周围不应有腐蚀性的气体或蒸汽,无电导性或爆炸性尘埃。

     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  安装场所无剧烈机械震动。

     No acutely vibration, jol is allowed.

2.3  海拔高度:不超过1000米。

     Altitude of installation place is not more than 1 km.

2.4  环境空气温度:户内 -25(-40)~+50℃。

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

2.5  空气的相对湿度不高于90%。

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

2.6  适用频率:  50~200 Hz。

     Application of frequency is 50~200 Hz.


  3  气动单极隔离开关结构简介  Brief introduction

  3.1  开关的绝缘支柱全部采用大爬距的瓷质支柱,12kV电压的产品其绝缘支柱采用环氧树脂压铸型。绝

   缘拉杆采用带硅橡胶伞群的环氧布棒。

        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型触板、导电杆和接线端子全部采用型材制造,并进行表面处理。其接触方式为线接触,它能保证接触

   良好、减小操作力和提高转动的灵活性。

        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  气缸采用无需润滑的国产优质气缸,免去用户在使用时需要定期在油雾器中注入润滑油。

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


  4  气动单极隔离开关工作原理

      The working principle of single pole pneumatic isolated switch

      气动单极隔离开关根据不同的电压及电流的大小,配用不同的气缸来进行操作,使之达到分、合闸

   的目的。气缸上均配有调速接头,可调整开关的分、合闸速度,在调速接头上有连接气路管子的连接头,只要

   将相应直径的管子插入即可。

        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.
