An improved transformer

Abstract

The utility model discloses an improved transformer. A user can start a circulation pump, so that the circulation pump extracts the cooling oil inside the transformer body through a connecting pipe and a tee, and then discharges the cooling oil into the inside of an S-bend pipe, so that the S-bend pipe transmits the temperature of the cooling oil to the heat dissipation fins. At the same time, the user can start a motor to drive the fan blades to rotate, so that the airflow quickly passes through the heat dissipation fins to take away the heat, and then the cooling oil is discharged into the inside of the oil tank, so that the cooling oil can be effectively circulated and dissipated quickly. When the cooling oil inside the transformer body heats up, the pressure inside the transformer body will increase, so that the air pressure drives the piston to slide inside the air chamber. At the same time, the piston drives the spring to compress. At the same time, the knob can be turned to drive the screw to rotate, so that the screw drives the push plate to move through the threaded sleeve, so that the pressure release of the device can be effectively adjusted.

[0007] Adopting the above technical solution: the user can start the circulation pump, so that the circulation pump extracts the cooling oil inside the transformer body through the connecting pipe and the tee, and then discharges the cooling oil into the inside of the S-bend pipe, so that the S-bend pipe transfers the temperature of the cooling oil to the heat dissipation fins.

When the cooling oil inside the transformer body heats up, the pressure inside the transformer body will increase, so that the air pressure drives the piston to slide inside the air chamber. At the same time, the piston drives the spring to compress. At the same time, the knob can be turned to drive the screw to rotate, so that the screw drives the push plate to move through the threaded sleeve, so that the pressure release of the device can be effectively adjusted.

[0008] The utility model is further configured that a knob is arranged on the top of the screw rod, and the bottom of the knob is bolted to the screw rod.

[0018] In summary, the utility model has the following beneficial effects:

[0019] 1. The user can start the circulation pump to draw out the cooling oil from the transformer body through the connecting pipe and the tee, and then discharge the cooling oil into the S-bend pipe, so that the S-bend pipe transfers the temperature of the cooling oil to the cooling fins. At the same time, the user can start the motor to drive the fan blades to rotate, so that the airflow quickly passes through the cooling fins to take away the heat, and then the cooling oil is discharged into the oil tank, so that the cooling oil can be effectively circulated and dissipated quickly;

[0020] 2. When the cooling oil inside the transformer body heats up, the pressure inside the transformer body will increase, causing the air pressure to drive the piston to slide inside the air chamber. At the same time, the piston drives the spring to compress.
