Abstract

The invention discloses a transformer air cooling control cabinet which comprises a cabinet body. Multiple rows of protection shells are fixed into the cabinet body, multiple cooling mechanisms are installed in an inner cavity of the bottom of the cabinet body, and each cooling mechanism is composed of a cooling fan and an air supply pipe, wherein one end of the air supply pipe is connected with the cooling fan, and the other end of the air supply pipe is connected with the protection shell; pipelines between the protection shells are mutually connected, and a wind direction regulation mechanism is installed on the portion, located at a connector of the two pipelines, of each protection shell; a control power supply adopts a reasonable dual power supply structural design pattern, one is taken from an external power supply, the other one is converted from power supply of the control power supply, the power supply reliability of the control power is greatly improved, air-cooled full stopcaused by controlling the power supply failure is effectively avoided, remote control input provides a communication interface, communication with a transformer substation central control room can beachieved, and the requirements of a digital transformer substation are met.

Description

technical field [0001] The invention relates to a transformer control cabinet, in particular to an air-cooled transformer control cabinet. Background technique [0002] Most of the energy consumed by the copper loss and iron loss of the transformer is converted into heat, which causes the temperature of the transformer winding and iron core to rise, and the insulation life of the transformer is closely related to the temperature. According to the test, when the average temperature per liter When the temperature is 10 degrees Celsius higher, the oil deterioration rate will increase by 1.52 times. Classified according to cooling method. At present, the transformers in power system operation are mainly three types: oil-immersed self-cooling type, oil-immersed air-cooled type and forced oil circulation type. Under the same environment, the cooling effect of forced oil circulation is better than that of oil immersion air cooling, and the cooling effect of oil immersion air cool...
