Oil-immersed transformer factory takes you to understand the fault handling of transformer bushings

A transformer is a device that uses an electromagnetic induction principle to change an alternating voltage. Its main components are a primary coil, a secondary coil, and a core (core). The main functions are: voltage conversion, current conversion, impedance transformation, isolation, voltage regulation (magnetic saturation transformer) and so on. Oil-immersed transformer factory takes you to understand what is the fault handling method of transformer bushing.
 
Transformer casing fault handling method:
 
1. In case of poor sealing of the casing, there is water ingress or oil leakage.
 
Remedy: Keep the seal by replacing the good quality rubber pad and tighten the fastening bolts so that the bushing has no leakage.

 2. For the casing oil sample is not qualified, containing acetylene gas and other defects.
 
Response measures: Strict inspection of the casing should be carried out, and all kinds of tests can be put into operation after being qualified to avoid malfunction caused by human factors. In the process of disassembly, connection and introduction, it is necessary to check whether the parts are well connected. The contact surface should be polished and coated with conductive paste to reduce the contact resistance. Thereby reducing its overheating.
 
3. Defects caused by overheating of the head due to unreasonable structure of the casing itself.
 
Countermeasures: The transition of copper-aluminum to silver-copper contact can be used to reduce its oxidation.
