1、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。

1, fasten the lead terminal, pin, ground screw and connecting line screw. If loose, remove the screws, or contact the contact surface with the thin flat file, or replace the spring washers and screws until the contact is good.


2、清洁箱式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。

2, clean the dust around the box type transformer and accessories, check the fire protection facilities and ventilation system is good.


3、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。

3. Disconnect the ground switch on the high pressure side and lock the high pressure joint. The insulation resistance is measured by the 2500V shake table. The insulation resistance should not be less than 70% of the original data when the transformer is out of the factory. If the failure is not qualified, it should be reported in time.


4、再次合上高压侧的接地开关,让变压器进行放电。

4, close the ground switch on the high side and let the transformer discharge.


5、检查变压室及变压器有无遗留工具,撤离现场。

5, check the pressure swing room and transformer have no legacy tools, evacuate the scene.


6、投入备用变压器,断开检修的箱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。

6, put in the standby transformer, disconnect the box transformer's low voltage side circuit breaker, take the operation insurance of the control power, and hang the "no closing" sign on the switch handle.


7、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。

7, disconnect the circuit breaker of the high voltage side of the transformer, close the grounding switch, discharge the transformer fully, lock the high voltage cabinet, and hang the sign of "Prohibition of closing" on the switch handle.


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。

For the maintenance of box type transformers, we first remove the porcelain bushing and shell, then check whether the shell, gaskets, porcelain bushing are cracked, discharge traces, or whether the rubber mats are aging, whether there are any deformation phenomena in the cables and busbars, and there should be replacement for the cracked ones.


8、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。

8, check whether the contact surface of the bus is kept clean, the contact surface should remove the oxide layer and apply the electric power compound grease.


9、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。欧冠赔率小编今天就分享到这里了。

9, check whether the grounding of the transformer is good, the ground wire is corroded, and the corrosion should be changed seriously. The small Guizhou switch cabinet is here today.
