How to solve the problems in power transformer?

1. the weld is leaking oil

Mainly the welding quality is bad, there is Weld, desoldering, weld pinhole, trachoma and other defects, the dry power transformers factory due to welding and paint cover, after the operation will be exposed to hidden dangers, the other due to electromagnetic vibration will make Welding crack, causing leakage. For the phenomenon has been leaking, first find out the leakage point, not missing. For the serious parts of the leakage can be used flat shovel or sharp red and other metal tools will be leaking point riveting, control the amount of leakage after the treatment of clean surface, most of the use of polymer composite materials for curing, curing can be achieved after long-term treatment The purpose of leakage.

2. seal oil leakage

Seal bad reasons, usually box along with the lid of the seal is the use of oil-resistant rubber rods or rubber pads sealed, if the joints are not handled properly will cause leakage of oil failure. Some with plastic banding, and some directly to the two ends of the pressure together, because the installation of rolling, the interface can not be crushed, not the role of sealing, or oil leakage. Can be used for the blessing of blue material bonding, so that the overall shape of the joints, oil leakage phenomenon is a lot of control; if the operation is convenient, you can also metal shell bonding, to achieve leakage management purposes.

3. flange connection leakage oil

Flange surface uneven, fastening bolts loose, the installation process is not correct, so that bolts fast, and cause leakage of oil. The first loose bolts for fastening, the flange sealing treatment, and for the possible leakage of the bolts are also processed to achieve the purpose of complete governance. The fastening of the loose bolts must be carried out in strict accordance with the operating process.

4. the bolt or pipe thread leaks the oil

Factory rough processing, poor sealing, 50kva power transformer seal after a period of time will produce leakage oil failure. The use of polymer materials to seal the bolt to achieve the purpose of governance leakage. Another way is to pull the bolt (nut), the surface coated with blessing blue release agent, and then in the surface after the application of material tightening, curing can be achieved after the purpose of governance.

5. cast iron oil leakage

The main reason for the leakage of oil is caused by sand and cracks in the cast iron. For crack leakage, drill hole is the best way to eliminate stress to avoid extension. Governance can be based on the case of cracks in the leak into the lead wire or hand horn riveting. Then use acetone to clean the leaks and seal with the material. Casting trachoma can be directly sealed with the material.

6. radiator oil leakage

Radiator heat pipe is usually made of stitched steel pipe after the stamping made in the cooling pipe bending part and welding part often produce leakage of oil, because the stamping heat pipe, the outer wall of the tube by the tension, the inner wall of the pressure , Due to the presence of residual stress. The radiator up and down the flat plate valve (butterfly valve) closed, so that the radiator oil and box oil cut off, reduce the pressure and leakage. To determine the leakage site after the appropriate surface treatment, and then use the blessing blue material for sealing treatment.

7. porcelain and glass oil oil leakage oil

Usually due to improper installation or seal failure. Polymer composite materials can be a good metal, ceramics, glass and other materials for bonding, so as to achieve the basic treatment of oil leakage.
