Abstract

The invention discloses an oil-immersed transformer based on a cooling protection device. The oil-immersed transformer comprises an oil tank shell, the cooling protection device, temperature control devices, a low-voltage bushing, a high-voltage bushing, a gas relay and an oil drainage valve; the cooling protection device is arranged on the upper side of the oil tank shell through welding, the oil drainage valve is connected to the lower end of the cooling protection device through a screw, the gas relay is connected to the lower side of the oil drainage valve through a bolt, the temperature control devices are arranged on the two sides inside the oil tank shell, the high-voltage bushing is arranged in the center in the oil tank shell, and the low-voltage bushing is connected to one side of the high-voltage bushing in parallel. According to the oil-immersed transformer based on the cooling protection device, by arranging the cooling protection device, heat dissipation and cooling functions are achieved, and safety protection is improved; by designing the temperature control devices, precise control over the temperature is achieved, and control convenience is increased; by designing the gas relay and the oil drainage valve, safety monitoring is promoted, and the safety is improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an oil-immersed transformer based on a cooling protection device. Background technique [0002] The body of the oil-immersed transformer, including windings and iron cores, is installed in an oil tank filled with transformer oil, and the oil tank is welded with steel plates. The oil tank of medium and small transformers is composed of a tank shell and a tank cover. The body of the transformer is placed in the tank shell, and the tank cover can be lifted out for maintenance. The oil-immersed transformer adopts a fully oil-filled sealed type. The corrugated oil tank shell adapts to the expansion of the oil with its own elasticity and is a permanently sealed oil tank. The oil-immersed transformer has been widely used in various power distribution equipment. The sealed oil-immersed Type transformers can be used for power distribution in various places such as industrial and min...
