Abstract

The invention relates to a device for automatically controlling flushing of a transformer cooler. The whole device includes an oil storage tank, a submersible oil pump, an oil filter unit, a filter, a valve, a pipeline and a control cabinet. The device takes the PLC controller as the control core to control the above-mentioned components to complete the processes of oil filling of the cooler, circulation of the submersible pump, circulation of the oil filter unit, and oil discharge of the cooler to realize flushing of the cooler. It saves time and labor, and it is convenient to control the oil speed and pressure.

Description

technical field [0001] The invention relates to a device for flushing a transformer cooler, in particular to a device for automatically controlling the flushing of a transformer cooler. Background technique [0002] Due to the impact of the climate, the transformer is affected by the wind and sand in spring and summer. The heat dissipation pipe of the transformer cooler is silted with sand and impurities, resulting in a higher operating temperature in summer. Sometimes the top oil temperature is close to the alarm value. In order to ensure the cooling effect of the transformer, it is necessary to regularly flush the transformer cooler with oil. . At present, the cooler is flushed by means of the oil connection pipe of the oil filter unit. One is the waste of oil resources, and the other is the need for manual control of flushing, which is time-consuming and laborious, and the oil pressure and flow rate are not easy to control. Contents of the invention [0003] In view o...
