Oil-immersed transformer is based on oil as the main insulation means of transformer, and relies on oil as the cooling medium, such as oil-immersed self-cooling, oil-immersed air cooling, oil-immersed water cooling and forced oil circulation. The main components of the transformer are iron core, winding, fuel tank, oil pillow, breathing apparatus, explosion-proof tube (pressure relief valve), radiator, insulation sleeve, tap changer, gas relay, thermometer, oil purifier and so on.

Product featureHeg

Due to oil's abillity to permeate between the layers of oil-immersed transformer silicon steel and its elastic buffering properties from prolonged immersion in the transformer, oil-immersed transformer noise is minimal.The Laminated Core Type Transformer has a high fill factor,an inscribed polygon cross section,and a multistage step lapped joint fully oblique structure that can reduce noise and magnetic resistance. After stress is eliminated by high tempreture annealing,no-load loss is significantly decreased.

The over signal ought to be installed,and the transformer is capable of operating in both normal and accidental overload scenarios.In the event that installing the overload signal is not possible,a thorough measuring device ought to be present.

The oil-immersed transformer's overload signal value ought to be between 1.1 and 1.2 times its rated current.Depending on the current of the fan when it is operating,the dry transformer's overload signal value should be between 1.2 and 1.3 times its rated current.

When the transformer overload signal is activated,it is important to monitor changes inthe load and temperature of the transformer.Additionally,the reason of the overload should be promptly inspected and ivestigated when conditions allow.There is a lot of overload overload-more than 1.3 times the rated current) or the temperature exceeds the upper limit should be reduced load.
