Oil Type Electrical Transformer Oil Leakage Reasons

Oil type electrical transformer is a key high-power electrical appliance. Its role in stabilizing the working standard voltage and current in the circuit is also very large. In order to achieve better expected results, oil-immersed transformers must be well The installation of oil-immersed transformers, the operation steps of installation and the order of installation should also be grasped in detail, which will determine the future use and full use of safety performance.

Oil type electrical transformer drain:

Before disassembly and assembly of spare parts, carry out heat dissipation and oil drainage of storage tank cabinets and heat pipes.

Before the oil drainage work, the storage tanks, gasoline drums, pipelines, vacuum oil filters, oil pumps, etc. should be checked and removed, and they should be kept clean and dry, free of dust, sediment and moisture, and airtight preventive measures should be taken after the removal. Remove oil, remove and install oil-immersed transformer parts, remove oil and move the hood.

Disassemble and assemble the high-voltage side transmission line of the oil type electrical transformer, disassemble and assemble the low-voltage side busbar, and drain the oil to the bottom of the automobile fuel tank.

Oil-immersed transformer hood:

① When hanging the cover, check the weather forecast, choose a bright sun, no wind and rain, and prevent moisture;

② The site of the hood is eliminated, and there is ample interior space for maintenance.

Reinstallation of finished oil-immersed transformers:

The body maintenance and experiment work is completed and all the standards are met, the cooling tower is opened, the transformer coil, magnet coil and oil tank are cleaned up, and the inspection work is neglected, whether there are any leftovers, etc., and check whether the commonly used maintenance tools are complete. After the above inspections are carried out, the bell can be dropped, the main switch of the tap power supply and the high and low voltage waterproof casings can be installed, the key air pipes above, the storage tank cabinet and the main switch of the no-load power supply can be installed. Before installation, all parts of the dry-type transformer should be overhauled, and the sealing gasket, silica gel, etc. should be removed. Make sure to pull and handle gently during all reloading process to avoid any harm.
