高压隔离开关结构解说

2014-1-8 9:31:28      点击:
高压隔离开关 有G N 19 - 10 ,G N 19 - 10 C ,相对应类似的老产品有G N 6 - 10 ,G N 8 - 10 。现以G N 19 - 10 为例,主要包括下述部分:
导电部分

由一条弯成直角的铜板构成静触头,其有孔的一端可通过螺钉与母线相连接;另一端较短(零件1,2),合闸时它与动刀片(动触头)相接触。
两条铜板组成接触条(零件3),又称为动触头,可绕轴转动一定角度,合闸时它夹持住静触头。两条铜板之间有夹紧弹簧(零件4)用以调节动静触头间接触压力,同时两条铜板,在流过相同方向的电流时,它们之间产生相互吸引的电动势,这就增大了接触压力,提高了运行可靠性。在接触条两端安装有镀锌钢片(零件6)叫磁锁,它保证在流过短路故障电流时,磁锁磁化后产生的相互吸引的力量,加强触头的接触压力,从而提高了隔离开关的动,热稳定性。
绝缘部分

动静触头分别固定在两套支持瓷瓶(零件12)上。对型号中带C的,动触头固定在套管瓷瓶上。为了使动触头与金属的,接地的传动部分绝缘,采用了瓷质绝缘的拉杆绝缘子(零件7)。
传动部分

有主轴,拐臂,拉杆绝缘子等。
底座部分

由钢架组成。支持瓷瓶或套管瓷瓶以及传动主轴都固定在底座上。底座应接地。总之,隔离开关结构简单,无灭弧装置,处于断开位置时有明显的断开点,其分合状态很直观。
