The auxiliary automatic cooling system comprises a temperature sensor used for collecting the temperature of a transformer radiator, the temperature sensor is sequentially connected with a temperature controller, a time relay, an intermediate relay and an electromagnetic water valve, the outputend of the electromagnetic water valve is connected to a spraying pipe through a hose, the spraying pipe is provided with a plurality of spraying nozzles, and the spraying nozzles face the direction where the transformer is located. The invention aims to provide an auxiliary automatic cooling system and method for the non-contact transformer to solve the problem of insufficient auxiliary cooling measures of the transformer in the prior art and realize the purposes of automatically cooling the transformer and being obvious in cooling effect.

Description

technical field [0001] The invention relates to the field of transformer cooling, in particular to a non-contact transformer auxiliary automatic cooling system and method. Background technique [0002] As the "heart" of the power grid, the transformer's safe and stable operation plays a decisive role in the safe and stable operation of the power grid. However, transformers often suffer from high operating temperature. Excessive operating temperature not only accelerates insulation aging, seriously reduces transformer life, but also reduces transformer load capacity, affects power supply safety, and even leads to unplanned outage of transformers, and even lifelong damage. Auxiliary cooling measures for the high operating temperature of the main transformer caused by high power supply load mainly include: first, pile up dry ice around the transformer to reduce the ambient temperature and accelerate the heat dissipation of the transformer. This method has obvious cooling effect...
