1、断开检修的箱式变压器低压侧断路器,取下控制电源的操作保险,在开关把手处悬挂“禁止合闸”标志牌。
1. Disconnect the low-voltage side circuit breaker of the box transformer for overhaul, remove the operation insurance of the control power supply, and hang the "No-Closing" sign at the switch handle.
2.断开检修变压器高压侧的断路器,合上接地开关,对变压器进行充分放电后,锁住高压柜,在开关把手处悬挂“禁止合闸”标志牌。
2. Disconnect the circuit breaker on the high-voltage side of the transformer for overhaul, close the grounding switch, after fully discharging the transformer, lock the high-voltage cabinet and hang the "No-Closing" sign at the switch handle.
3.箱式变压器的保养,首先清扫瓷套管和外壳,其次检查外壳、垫片、瓷套管有无破裂、放电痕迹或胶垫有无老化,电缆及母线有无变形现象,有破裂的应进行更换。
3. Maintenance of box transformer should first clean the porcelain bushing and casing, and then check whether the casing, gasket and ceramic bushing are cracked, discharged traces or rubber pad are ageing, whether the cable and busbar are deformed or not, and if they are broken, they should be replaced.
4.检查母线接触面是否保持清洁,接触面应除去氧化层并涂以电力复合脂。
4. Check whether the bus contact surface is kept clean. The contact surface should be removed and coated with electric compound grease.
5.检查变压器的接地是否良好,地线是否腐蚀,腐蚀严重的应更换。
5. Check whether the grounding of the transformer is good or not, whether the ground wire is corroded, and if the corrosion is serious, it should be replaced.
6.紧固引线端子、销子、接地螺丝、连线母线螺丝,如有松动的应拆下螺丝,或用细平锉轻锉接触面,或更换弹簧垫圈、螺丝,直至接触良好。
6. Tighten lead terminals, pins, grounding screw and connecting bus screw. If loose, remove the screw, or use thin flat file to lightly file contact surface, or replace spring washer and screw until good contact.
7.清洁变压器周围及配件上的灰尘,检查消防设施及通风系统是否良好。
7. Clean the dust around the transformer and its fittings and check whether the fire fighting facilities and ventilation system are in good condition.
8.断开高压侧的接地开关,并锁好高压开关节栉,用2500V摇表测定绝缘电阻。并与变压器出厂前测定值比较,绝缘电阻不应低于出厂时原始数据的70%,若不合格应及时上报处理。
8. Disconnect the grounding switch on the high-voltage side and lock the high-voltage switch bars. Measure the insulation resistance with 2500V shake table. Compared with the measured value before leaving the factory, the insulation resistance should not be lower than 70% of the original data when leaving the factory. If it is not qualified, it should be reported and processed in time.
9.再次合上高压侧的接地开关,让变压器进行放电。
9. Close the grounding switch on the high-voltage side again and let the transformer discharge.
10.检查变压室及变压器有无遗留工具,撤离现场。
10. Check whether the transformer chamber and transformer have any left-over tools and evacuate the site.
11.接上低压侧断路器控制电源操作保险,重新挂上“禁止合闸”标志牌,防止向变压器反送电。
11. Connect the low-voltage side circuit breaker to control the operation insurance of the power supply, and re-hang the "no-closing" sign to prevent the reverse transmission of power to the transformer.
12.断开高压侧接地开关,再次检查变压器现场及低压侧的控制线,无误后,合上变压器高压侧断路器,让变压器试运行取下高压侧标志牌。
12. Disconnect the grounding switch on the high-voltage side, check the control line on the zhongyaocai.71ix.combaohuqi.07858.netzaoxingzd.37ix.com.cnlangfang.71ix.cntransformer site and the low-voltage side again. After that, close the high-voltage side circuit breaker of the transformer and let zhongyaodou.71ix.comkakou.37ix.com.cnthe transformer test run and remove the high-voltage side sign.
13.详细做好保养试运行记录。
13. Make detailed maintenance and trial operation records.
