Transformer - how to adjust the gear of oil-immersed transformer

For common oil-immersed transformers, it is necessary to pay attention to the methods and efficiency in the work. Improving the efficiency and efficiency of oil-immersed transformers relies on the gears of oil-immersed transformers, so it has the gears for adjusting transformers. How to carry out the actual operation when adjusting the gear of the oil-immersed transformer?

Oil-immersed transformer gear classification:

It is generally divided into two types: on-load voltage regulation and non-excitation voltage regulation. On-load voltage regulation is fully automatic voltage regulation by the application of tap power switch, which can be operated with a little bit of practice. Non-excitation voltage regulation is only manual voltage regulation after power failure. There is a gear position indication on the high-voltage coil of the pressure city. It can be adjusted according to your working voltage application regulations.

Oil-immersed transformer gear adjustment process:

First check whether there is a load voltage regulation or no-load voltage regulation. The former one should be adjusted immediately, the latter one must be turned off, and the latter one should be oil-free or dry. Put a power switch cover on the cover of the oil-free phone, open the cover, and screw on the gear. Use a wrench to replace the sub-rotating piece on the electromagnetic coil with the connector part, and the gear position is marked on the factory nameplate or instruction manual.
