FZW32-12D/T630-20、FZW□-40.5D/T1250-25

概述 General
  FZW32-12D/T630-20型户外高压隔离真空负荷开关及FZW□-40.5D/T1250-25型户外高压隔离真空负荷开关(以下简称负荷开关),各项技术性能指标达到GB3804和IEC标准,适用于三相交流50Hz、额定电压12kVe及40.5kV的供电网络中,广泛用于农网、城网及铁路等配电线路的改造,尤为适用于频繁操作场所。
  负荷开关是由隔离刀和真空灭弧组成,隔离刀承担了合闸和分闸时绝缘作用,真空灭弧室承担熄灭电弧的作用,无爆炸危险、不需检修、开断能力大、电寿命、隔离刀与三相真空灭弧室联动,分闸时有明显的断口,安全可靠。
  安装方式:FZW32-12D以单杆式、手动操作为主,也可采用电动或远程遥控操作,而FZW□-40.5D以双杆式、电动操作为主,也可采用手动或远程遥控操作。
  隔离刀是由弹簧过中机构进行合分闸操作的,过中弹簧提供了隔离刀合闸时所需的能量,并保证真空灭弧室在分闸时熄灭电弧而不受人为因素的影响,真空灭弧在隔离刀的分闸过程中,有快速机构提供灭弧室的分闸速度。隔离刀的三相联动操作确保了灭弧室的分闸同期性。

  FZW32-12D/T630-20 a high vacuum out from the switch and business FZW□-40.5D/T1250-25 a high vacuum out from under the load switch(short switch), and the technical performance indicators and iec standard, reached GB3804 applicable to communicate with a three wire 50Hz, and the rated working voltage 12kv and 40.5kv the supply of the internet, widely used in the city and the railway network,for distriibution line of reform, especially suitable for operation.
  The switch is made from a knife and a the knife of apartheid have undertaken to brake and the role and vacuum insulated in the bear out the role of arc, and explosion danger, don’t need to be overhauled and a power large,longer,with a knife with a three wite off the winding,when the significant and reliable,safe.
  Installation method: FZW32-12D style, with manual operation and can also use the electric or remote area, and FZW□-40.5D with the type and electric operation, or using manual or a remote area.
  Isolation a knife is the spring over the body on to the operation of the spring,and provided to isolate the knife when the required energy, and the vacuum in the light when electric arc by artificial factors, the vacuum out of arc in the process and provides the rapid pace.from the sword with a three wire winding up the operation to ensure the synchrouis.
