A high-efficiency cooling filter oil-immersed transformer for power transmission system

Abstract

The invention relates to an efficient cooling filtration oil-immersed transformer for a power transmission system. The efficient cooling filtration oil-immersed transformer comprises an oil-immersed transformer body and an oil tank; the oil tank is provided with an oil outlet pipe and an oil inlet pipe, the oil outlet pipe is connected with a three-way valve through an oil pump, and the output ends of the three-way valve are connected with a first pipeline and a second pipeline respectively; the first pipeline is connected with a cooling device through a cooling pipeline, the output end of the cooling device is connected to the oil inlet pipe, the second pipeline is connected with a filtration device, the output end of the filtration device is connected with the cooling pipeline through a third pipeline, and the first pipeline and the third pipeline are each provided with a one-way valve. The oil outlet pipe and the oil inlet pipe are arranged to lead transformer oil in the oil tank out to be cooled and filtered, the transformer oil in the oil tank of the oil-immersed transformer can be effectively cooled and filtered, therefore, the temperature of the transformer oil is fully lowered, and the cleanliness degree of the transformer oil is kept. The efficient cooling filtration oil-immersed transformer is reliable in design principle and simple in structure, and has a very wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and relates to power transmission system equipment, in particular to a high-efficiency cooling filter oil-immersed transformer for power transmission system; the oil-immersed transformer can effectively filter the oil-immersed transformer oil tank through an external cooling filter device The transformer oil inside is cooled and filtered to fully reduce the temperature of the transformer oil and keep the cleanliness of the transformer oil.
