C 9-5（8）图9-6 6脉冲晶闸管整流器9.4.1准备步骤1断开驱动器电源。见第9.2节安全。2拆除保险丝和保险丝支架，以便能够拆除晶闸管（见图9-8）。切断固定晶闸管栅极线的电缆扎带，并将其从脉冲变压器上拆下。3交替松开夹紧螺栓，直到可以用手转动，然后松开可控硅（见图9-7）。为防止卡箍掉落，请勿完全打开螺栓。图9-7松开螺栓9.4更换直接励磁夹具EXU中的晶闸管第9章-更换EXU ABB 9-6（8）3BHS202077 ZAB E01 Rev.C ACS 6000维护手册4从塑料导轨中拉出损坏的晶闸。图9-8拆除晶闸管5从断开的晶闸管上拆除栅极线。9.4.2安装前处理新晶闸管1检查接触表面是否有划痕、划痕、凸起和表面光洁度（平整度和粗糙度）。2将栅极线连接到新的晶闸管。3使用尼龙海绵，通过圆周运动小心地研磨配合面。研磨时要特别注意不要暴露铜。用甲醇液体和不易燃布擦拭磨损的半导体表面，并涂上一薄层导热化合物C 9-5 (8) Figure 9-6 6-pulse Thyristor Rectifier 9.4.1 Preparatory Steps 1 Deenergize the drive. See section 9.2 Safety. 2 Remove the fuse and the fuse support in order to be able to remove the thyristor (see Figure 9-8). Cut off the cable tie securing the thyristor gate wires and remove them from the pulse transformer. 3 Loosen the clamp bolts alternately until they can be turned by hand and loosen the thyristor (see Figure 9-7). To prevent the clamp from dropping, do not open the bolts completely.

C ACS 6000 Maintenance Manual 4 Pull the broken thyristor out of the plastic guide. Figure 9-8 Removing a Thyristor 5 Remove the gate wires from the broken thyristor. 9.4.2 Treating a New Thyristor before Installation 1 Check the contact surfaces for nicks, scratches, bulges and surface finish (flatness and roughness). 2 Connect the gate wires to the new thyristor. 3 Using a nylon sponge, carefully abrade the mating surfaces by applying circular movements.Take special care not to expose the copper when abrading. Wipe the abraded semiconductor surfaces clean with methanol liquid and non-flammable cloth and apply a thin layer of heat-conducting compound
