Description

Technical Field

[0001] The invention belongs to the field of transformers, and in particular relates to an automatic cleaning liquid cooling device for outdoor transformers. Background Art

[0002] Transformers generally operate at low frequencies and with conductors wound around the core to form windings. When the transformer is in operation, the transformer will heat up due to operating losses. In order to reduce the operating temperature of the transformer, the transformer is often cooled by a liquid cooling device. However, in the hot summer and during peak hours of electricity consumption, the transformer needs to be in full load operation. Due to untimely maintenance such as foreign matter attached to the cooling device, the transformer often operates abnormally, endangering the safe and stable operation of the power grid. For example, the patent with announcement number CN105609262A discloses a water-cooled transformer, including a transformer, the upper end of the transformer is connected to a water collecting tank through a support frame, a self-priming pump is fixedly installed on the inner middle part of the water collecting tank, a circulating water tank is provided inside the transformer, the outer surface of the circulating water tank is a heat dissipation copper plate, an electric motor is fixedly installed inside the circulating water tank, and a paddle is set on the surface of the rotating shaft of the electric motor. The water-cooled radiator can circulate water to cool the inside of the transformer, but its cooling device is exposed to the outside and is affected by the environment and requires frequent manual maintenance; or the patent with patent number CN112331460A discloses a high-efficiency cooling transformer, including a base box, a heat dissipation wall and a temperature control top, wherein the three are mutually clamped and connected, a cooling cavity and a connecting cavity are provided in the heat dissipation wall, a liquid extraction pipe and a reflux pipe are installed on the upper surface of the base box, and the base box, the heat dissipation wall and the control top are connected by connecting the base box, the heat dissipation wall and the control top. The temperature tops are hinged to each other, and the traditional integral structure transformer is changed into an assembly structure with mutual clamping connection, which is convenient for the transportation, installation and disassembly of the transformer, and is beneficial to the maintenance and other operations of the transformer by the staff; or as the patent application with announcement number CN205789398U, discloses an outdoor transformer circulation cooling device, and its specification paragraph 0014 discloses: when the outdoor transformer circulation cooling device is used, the heat on the transformer is transported to the heat dissipation plate for heat dissipation by the heat conduction device at the bottom of the transformer, and cold water is heated in the first connecting pipe and the second connecting pipe, and the cold water in the first connecting pipe and the second connecting pipe is formed into circulating water by a water pump, and the circulating water is cooled by the cooling device, and the heat dissipation pipe is used to cool the transformer, so that the temperature around the transformer is not too high. The two heat dissipation methods can improve its heat dissipation efficiency and ensure the normal operation of the transformer.

[0003] However, in actual use, the temperature on one side of the heat sink needs to be dissipated through a heat pipe. Since the dirt attached to the inner wall of the heat pipe needs to be cleaned regularly, the heat pipe needs to be fixed to one side of the transformer body by screws. This fixing method will affect the efficiency of disassembly of the heat pipe and reduce the efficiency of cleaning the dirt attached to the inner wall of the heat pipe.

[0004] Therefore, an automatic cleaning outdoor transformer liquid cooling device is proposed to solve the above-mentioned drawbacks. Summary of the invention
