Abstract

The invention relates to an automatic water cooling system for a main transformer. The system comprises a power module, a temperature sensor, a temperature compensation module, a switch assembly and awater cooling module, wherein the switch assembly comprises a temperature relay and an intermediate relay; the water cooling module comprises a booster pump, a solenoid valve for water, a first one-way valve, a spray head and a water pipe; the temperature sensor is arranged on the main transformer and can collect temperature data of the main transformer in real time and send the temperature datato the temperature compensation module. When the temperature exceeds a preset temperature threshold value of the temperature compensation module, the temperature module sends out a cooling signal, andopening and closing control over the booster pump and the water valve is achieved through the switch assembly. The system automatically sprays water to cool and dissipate heat when the temperature rise of the main transformer is too high, the cooling effect is good, and the overtemperature time of the main transformer is effectively shortened.

Description

technical field [0001] The invention relates to the field of water cooling and cooling, and more particularly relates to an automatic water cooling and cooling system for a main transformer. Background technique [0002] During the peak summer season, some main transformers were operating under heavy loads, and the oil temperature of the main transformers soared, generally reaching more than 70 degrees Celsius, and even reaching 85 degrees Celsius. The high oil temperature of the main transformer seriously threatens the operation safety of the main transformer. When the temperature of the main transformer is close to or exceeds the maximum temperature allowed by the operating regulations, and the heat dissipation of the main transformer itself is limited, the usual practice is to reduce the temperature by pressing the load, suspending the power consumption of industrial users and special users, and shutting down the main transformer. All these measures will cause unnecessar...
