短路容量 Short-circuit capacity
隔离开关的触头系统中,每条接触线只通过1/4电流,闭合时每条接触线的电动反力减少为原来的(1/4)²即1/16,而在触头闭合 后,途行径滚柱的电流形成一夹紧的电动力,夹紧的力(防止触头分开的力)随电流的增加而增加,在极限故障情况下,这电流大于 100kA。
In the contact system of the disconnector,each contact ine only passes 1/4of the curent,and the electric reaction force of each contact line is reduced to the original(1/4),that is,1/16 when closed,and after the contact is closed,the current of the rollr forms a clamping electrodynamic force,and the clamping force (the force preventing the contact from separating)increases with the increase of current,and in the case of extreme faults,this current is greater than 100kA.
分断容量Breaking capacity
隔离开关的新型触头系统可把分断过程分配给每相的四个分断点,从而使开关具有了极限分断能力,这种分配的结果又使燃弧时间 和触头的发热都减小了,进而延长了触头寿命。
The new contact system of the disconnector distributes the breaking process to four breaking points in each phase,so that the switch has the limit breaking capacity,and the result of this distribution is that the arc time and heat generation of the contact are reduced,thereby extending the contact life.
