Cooling mechanism of energy-saving type power transformer

Abstract

The invention discloses a cooling mechanism of an energy-saving type power transformer. The cooling mechanism comprises three-phase windings installed inside a transformer box body, wherein a cooling pipe is twined outside each of the three-phase windings, one end of the cooling pipe is connected to an air pump, and the other end of the cooling pipe stretches out of the transformer box body. The cooling mechanism of the energy-saving type power transformer provided by the invention is simple in structure, and air is introduced into the cooling pipe through the air pump, so that the purpose of cooling windings inside the power transformer can be realized, thus the power transformer can be quickly cooled in a safe and reliable way, the dead weight of the power transformer can be reduced, and the material and cost can be saved; and meanwhile, the situation of oil leakage caused by the cooling of insulating oil can be avoided.

Description

technical field [0001] The present disclosure generally relates to the field of transformers, in particular to energy-saving power transformers, and in particular to a cooling mechanism for energy-saving power transformers. Background technique [0002] A power transformer is a static electrical device that is used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. Power transformers are one of the main equipment in power plants and substations. The role of the transformer is multifaceted. It can not only increase the voltage to send electric energy to the power consumption area, but also reduce the voltage to the voltage of all levels to meet the needs of power consumption. In short, both step-up and step-down must be done by the transformer. In the process of electric energy transmission in the power system, two parts of voltage and power will inevitably be lost. When the same power is ...

Problems solved by technology

[0003] During the working process of the power transformer, the three-phase winding generates heat due to the current passing through it, thereby generating a temperature rise around the three-phase winding. In order to reduce the temperature of the three-phase winding, the common practice is to immerse the three-phase winding in insulation In the oil, through heat exchange, the heat of the three-phase winding is reduced, thereby reducing the temperature around the three-phase winding, but the risk factor of using insulating oil is large, which increases the power transformer and is also prone to oil leakage.
