Working principle of transformer cooler Function of transformer cooler

The working principle of transformer cooler is to transfer the heat of the transformer out through heat dissipation to maintain the normal operation of the transformer. temperature device. The function of the transformer cooler is to ensure that the transformer can operate within a reliable and safe temperature range and extend the service life of the transformer.

There are two main working principles of transformer cooler: natural cooling and forced cooling.

Free cooling means that the transformer uses natural convection to dissipate heat to the surrounding environment. A free cooler usually takes the form of a radiator, usually consisting of a series of fins and cooling oil. The cooler is installed on the top or side of the transformer to dissipate heat through cold oil circulation. When the transformer is running, a large amount of heat will be generated inside the transformer, causing the temperature of the transformer to rise. The heat is conducted to the cooling oil through the coil and core. As the cooling oil flows through the radiator, it dissipates heat through radiation and convection, thereby reducing the temperature of the transformer.

Forced cooling refers to accelerating the heat dissipation process through external cooling devices. Generally speaking, when the current or load of the transformer is high, natural cooling often cannot meet the requirements for the transformer temperature. At this time, a forced cooler is needed to improve the cooling effect. Forced coolers typically include components such as fans, coolers, and coolant. The forced cooler uses a fan to reduce the temperature of the coolant to a suitable range, and then conducts the heat to the ambient air through the cooler fins. This method can effectively reduce the temperature of the transformer and improve the operating efficiency and reliability of the transformer.

The function of the transformer cooler is to ensure that the operating temperature of the transformer is stable and reasonable. When the temperature of the transformer is too high, it will cause the insulation material to age, the electrical performance to decrease, and even cause short circuits, explosions and other faults. Through the device of the transformer cooler, the heat generated inside the transformer can be transferred out in a timely and effective manner, keeping the transformer operating within a safe temperature range and avoiding the above problems. At the same time, a good cooling device can also reduce the temperature rise of the transformer, improve the load capacity of the transformer, and extend the service life of the transformer.

The transformer cooler realizes heat dissipation of the transformer through natural cooling and forced cooling to ensure that the transformer operates within a safe temperature range. The function of the transformer cooler is to protect the electrical and mechanical properties of the transformer, extend the service life of the transformer, and improve the reliability and operating efficiency of the transformer. Therefore, when designing and selecting transformers, it is very important to properly select and configure the cooling device.
