The oil conservator is also called auxiliary oil tank. It is a barrel descriptor made of steel plate. It is horizontally installed on the transformer oil tank cover and connected with the oil tank with a curved connecting pipe. One end of th...

When the primary coil has an AC transformer principle process, an AC magnetic flux is generated in the iron core (or magnetic core), causing the secondary coil to generate an induced voltage (or current). Under the rated power, the ratio of ...

Using load switch to increase the breaking capacity of backup current limiting fuse is more effective than using circuit breaker, and sometimes the latter may not even play an effective protective role. Using load switch to increase the brea...

Oil immersed transformer occupies a large market share in China, but the oil leakage of oil immersed transformer is also a disadvantage of this type of transformer. Over the years, manufacturers and users have been looking for solutions and ...

We know that the transformer establishes the main flux to transfer energy. Whether the transformer is under light load, heavy load or no-load, the main flux is the same, but the transfer energy is different. Is there another quantity in the ...

1. Winding copper loss boring method: through the transformer winding, the power generation itself generates heat, heats the winding insulation, has small operation volume, fast temperature rise and saves time. The defect is that the workloa...

We can often see that a large number of pebbles are placed under some transformers, so what are these pebbles for? Once an incident occurs, the pebbles can prevent oil splashing in the transformer and blasting. Once an incident occurs, the p...

1. Short circuit the "input" and "output" terminals of the transformer, and test the insulation resistance between them and the ground wire with a megger. When measured by 1000V megger, the resistance is greater than 2m Ω. 2. The section wi...
