Abstract This article focuses on the problems of poor spraying effect, inability to automatically control according to the load oil temperature of the main transformer and control lag in the existing transformer water spray cooling device. A stereo type spray cooling method that includes top nozzle, side wall nozzle and environmental nozzle is proposed. A local control cabinet is designed to separate the electrical control circuit from the water circuit, and a control logic combining manual control, automatic control and remote control is used to realize automatic control of the device, improving the cooling effect of spraying. On-site application shows that the device can achieve intelligent auxiliary cooling above 6℃, reducing the waste of manpower and material resources.
