Technical Field
[0001] The utility model relates to the technical field of transformers, in particular to a high-efficiency energy-saving water-cooled transformer. Background Art
[0002] A water-cooled transformer is a transformer that uses water cooling. Its characteristic is that it uses the large specific heat capacity of water to take away the heat generated by the transformer through water circulation, thereby achieving effective heat dissipation. This cooling method is suitable for large, high-power transformers because it can provide very good heat dissipation effects and is widely used.
[0003] The existing water-cooled transformers have the following disadvantages during use: water-cooled transformers are generally equipped with a liquid tank structure for storing coolant, and the coolant stored inside the tank and the heated coolant inside the transformer are continuously circulated to achieve continuous cooling of the transformer. After the existing coolant is recovered into the liquid tank, natural cooling or air cooling is generally used for heat dissipation. The natural cooling method is less efficient, and air cooling requires long-term continuous cooling treatment, which consumes more energy. For this reason, we propose a high-efficiency and energy-saving water-cooled transformer. Utility Model Content

[0007] Furthermore, it also includes an isolation mechanism, an isolation mechanism is arranged at the top of the water collecting cover, the isolation mechanism includes a fixed plate, a rotating shaft, a movable plate and a torsion spring, the water collecting cover is located at the bottom of the filter plate and is fixedly connected with a fixed plate, the end of the fixed plate is installed with a rotating shaft and is movably connected with the movable plate through the rotating shaft, and a torsion spring is installed at the connection between the fixed plate and the movable plate; on rainy days, rainwater passes through the filter plate into the water collecting cover and falls onto the top of the fixed plate and the movable plate, when there is more rain on the top of the movable plate, the torsion spring is deflected under the action of gravity, causing the movable plate to shift around the rotating shaft, and the rainwater enters the bottom end of the water collecting cover, and then the movable plate is automatically reset under the action of the torsion spring, and its end is in contact with the inner wall of the water collecting cover, playing a closed and isolating role, which can reduce the evaporation of water inside the water collecting cover.
[0008] Furthermore, the outer wall of the liquid return pipe is fixedly connected with a heat dissipation ring located inside the water collecting cover; the heat dissipation ring expands the heat exchange structure area and improves the heat dissipation efficiency.

A liquid tank 201 for storing coolant is installed on the top of the transformer body 1, and the water collecting cover 202 is fixedly connected to one side of the surface of the liquid tank 201. A liquid return pipe 203 that runs through the inside of the water collecting cover 202 is installed between one end of the liquid tank 201 and the transformer body 1, and a liquid discharge pipe 204 is installed at the other end of the liquid tank 201. A bracket 208 is welded on the top of the water collecting cover 202, and a filter plate 209 is obliquely overlapped on the top of the bracket 208.
[0018] The water collecting cover 202 further includes an isolation mechanism 3, the isolation mechanism 3 is provided at the top of the water collecting cover 202, the isolation mechanism 3 includes a fixed plate 301, a rotating shaft 302, a movable plate 303 and a torsion spring 304, the fixed plate 301 is fixedly connected to the bottom of the filter plate 209 in the water collecting cover 202, the rotating shaft 302 is installed at the end of the fixed plate 301 and the movable plate 303 is movably connected through the rotating shaft 302, and a torsion spring 304 is installed at the connection between the fixed plate 301 and the movable plate 303; On rainy days, rainwater passes through the filter plate 209 and enters the water collecting cover 202 and falls onto the top of the fixed plate 301 and the movable plate 303. When there is a lot of rainwater on the top of the movable plate 303, the torsion spring 304 deflects under the action of gravity, causing the movable plate 303 to shift around the rotating shaft 302, and the rainwater enters the bottom position inside the water collecting cover 202. Then, the movable plate 303 automatically resets under the action of the torsion spring 304, and its end is attached to the inner wall of the water collecting cover 202, which plays a closed and isolating role, thereby reducing the evaporation of water inside the water collecting cover 202.
[0019] Among them, the outer wall of the return liquid pipe 203 is fixedly connected to a heat dissipation ring sheet 205 located inside the water collecting cover 202, and a drainage hole 206 is opened at the bottom of one side of the surface of the water collecting cover 202, and a piston 207 is inserted into the drainage hole 206; the heat dissipation ring sheet 205 expands the heat exchange structure area and improves the heat dissipation efficiency.

[0021] It should be noted that the utility model is a highly efficient and energy-saving water-cooled transformer. When working, the used cooling water inside the transformer is discharged into the liquid tank 201 through the return pipe 203 under the action of the circulation component. The coolant inside the liquid tank 201 enters the transformer body 1 through the discharge pipe 204. A water collecting cover 202 is provided at the outer peripheral position of the return pipe 203. Rainwater can fall into the water collecting cover 202 for collection in rainy weather. The filter plate 209 prevents impurities from falling in. After the temperature inside the liquid tank 201 rises, the coolant passes through the water collecting cover 202 when it flows back, and the rainwater collected inside is used to play a certain heat dissipation and cooling effect on the coolant, and then flows back. After reaching the inside of the liquid tank 201, the heat dissipation energy consumption of the air-cooling component is reduced, the cooling efficiency is improved, and the purpose of energy saving and efficiency improvement is achieved; on rainy days, rainwater passes through the filter plate 209 into the water collecting cover 202 and falls on the top of the fixed plate 301 and the movable plate 303. When there is a lot of rain on the top of the movable plate 303, the torsion spring 304 is deflected under the action of gravity, causing the movable plate 303 to shift around the rotating shaft 302, and the rainwater enters the bottom end position inside the water collecting cover 202. Then, the movable plate 303 is automatically reset under the action of the torsion spring 304, and its end is attached to the inner wall of the water collecting cover 202, which plays a closed and isolating role, and can reduce the evaporation of water inside the water collecting cover 202.
