Description

A Transformer Water Cooling System

technical field

The invention belongs to the technical field of transformer cooling and cooling, and in particular relates to a transformer water cooling system.

Background technique

The stable operation of the transformer is related to the stability of the entire power grid. During the operation of the transformer, a high temperature will be generated. Due to the limited heat dissipation of the transformer itself, when the temperature of the transformer in the substation is close to or exceeds the maximum temperature allowed by the operating regulations, the transformer will be Stop running, reducing the reliability of power supply. Currently commonly used cooling devices are: refrigeration air conditioners or cooling fans, etc., which have certain advantages and disadvantages; refrigeration air conditioners, which have a good cooling effect, but have complex structures, large energy consumption, and high prices; use groundwater to cool down There are fewer running parts and a relatively simple structure, but the water consumption is large, and the cooling effect is not ideal; and the cooling fan is used to cool down, and the air flow around the transformer is accelerated through the rotation of the cooling fan, so that the surface of the transformer and the flowing air perform heat exchange. , although it has a simple structure and low water consumption, due to the high ambient temperature in summer, the cooling effect of the transformer through air flow is poor. In addition, in the prior art, nozzles are installed around the transformer body and heat pipes to spray water onto the transformer cooling fins to cool down the transformer. For example, the patent No. CN201220661381.4 discloses a transformer cooling and cooling device, which includes control Devices such as valves, sprinklers, automatic control devices and UPS power supplies. This type of spray cooling device has the following disadvantages: First, the structure is complex, the effective area sprayed onto the heat sink is small, and the cooling effect is poor. The second is that the cooling device is not safe to work, because the components and lines arranged around the transformer are close to the conductor, which may easily cause the components of the device to be burned and cannot continue to work effectively. At the same time, there are safety hazards in installation and maintenance; the third is spraying The device consumes a lot of water and cannot use water resources efficiently. Therefore, it is necessary to further develop a safe and efficient transformer water cooling system.
