隔离开关的调整
In the following sections you can find the procedures for the adjustment and fine
tuning of the equipment.
以下各节里，你将看到的是设备的调整程序和微调程序。
6.5.1 Adjustment of the live part (Fig. 2E, 2F)
过流部件的调整（图
2E
，
2F
）
Carry out a slow CLOSING operation and check that all the male contacts are
centered when they reach the female contacts (Fig. 2E).
执行缓慢合闸的操作并检查当所有雄触头接触到雌触头（图
2E)
时它们都处于中心位
置。
In the CLOSED position, check that the male and female arms complete their travels
(about 90°), they are aligned (tolerance ±2°) and that all the conditions shown in
figures 2E and 2F are met.
在合闸位置时，检查当雄刀臂和雌刀臂完成其行程时（大约
90
°），它们是对准的（
误差±
2
°），而且如图
2E
和
2F
所示的全部条件均得到满足。
Check also that the arms engage for a distance of 25 mm (tolerance -10 / +30), as
shown in figures 2, 2A and 2B.
同样检查雄刀臂和雌刀臂的咬合深度为
25mm(
误差
-10/+30)
，如图
2
，
2A
和
2B
所示
。
With the special crank or lever of the drive of the disconnector, OPEN (with opening
angle 90°±4°) slowly the disconnector and check that the male contacts separate as
shown in figure 2E.
使用专用曲柄或隔离开关操作机构的控制杆，慢慢打开（开闸角度为
90
°±
4
°）隔
离开关并检查雄触头如图
2E
所示的那样分开。
If needed, you can also adjust the upper or lower part of the insulator, thanks to the
freedom of positioning of the fastening holes.
