Description

Technical Field

[0001] This utility model relates to the field of substation technology, specifically to a 35KV high-voltage bay structure for substations. Background Technology

[0002] In current power transmission and distribution systems, American-style prefabricated substations (referred to as "American substations") are widely used due to their compact structure and convenient installation and maintenance. Especially in urban power distribution networks, industrial areas, and centralized residential power supply applications, American substations significantly improve space utilization and power supply flexibility through their integrated design. However, some technical challenges remain in the design of the high-voltage bay structure within American substations.

[0003] In existing technologies, the high-voltage bay structure of American-style prefabricated substations typically integrates key components such as high-voltage load switches, insertion fuses, and other control and protection devices into a single sealed oil tank. While this highly integrated design helps reduce equipment size, it also presents heat dissipation challenges. Specifically, the transformer oil within the tank not only bears the heavy responsibility of insulation but also needs to handle the heat load generated by the operation of all high-voltage components. Traditionally, these tanks rely primarily on external heat sinks and cooling fans for temperature management. However, this cooling mechanism is relatively slow in practical use, and over time, the transformer oil, operating under high temperatures, gradually ages and produces deposits such as sludge and residue. These deposits not only reduce cooling efficiency but may also cause physical wear or insulation degradation to the precision components inside the high-voltage bay, increasing maintenance costs and safety hazards. Currently, no effective solutions have been proposed to address these issues. Therefore, a 35kV high-voltage bay structure for American-style substations is needed to solve the aforementioned problems. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a 35KV high-voltage bay structure for transformers to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A 35kV high-voltage bay structure for transformers includes a transformer body, an oil tank fixedly connected to one side of the transformer body, a high-voltage load switch fixedly installed on one side of the inner wall of the oil tank, a high-voltage fuse fixedly installed on one side of the high-voltage load switch, an oil outlet pipe installed on one side of the bottom of the oil tank, a transmission pipe rotatably connected to one end of the oil outlet pipe, a support frame installed on the outer side of the oil tank, a transmission heat dissipation mechanism fixedly installed on one side of the support frame, and a collection and filtration mechanism fixedly installed on the top of the transmission pipe.

[0007] Furthermore, in order to achieve heat dissipation through transmission of the oil in the tank, the heat dissipation mechanism includes a driven gear fixedly mounted on the surface of the transmission pipe, a transmission motor fixedly mounted on one side of the surface of the support frame, a driving gear fixedly connected to the transmission shaft of the transmission motor, the driving gear meshing with the driven gear, a sliding groove opened on one side of the support frame, a heat dissipation pipe fixedly connected to the surface of the transmission pipe, and a caster wheel fixedly mounted on one side of the heat dissipation pipe, the caster wheel slidingly mounted in the sliding groove.

[0008] Furthermore, in order to filter the transformer oil, the collection and filtration mechanism includes a collection tray rotatably connected to the top of the transmission pipe, a filter screen fixedly installed inside the collection tray, an oil extraction pipe fixedly connected to the top of the collection tray, an oil extraction pump fixedly installed at one end of the oil extraction pipe, and an oil inlet pipe fixedly installed on one side of the top of the oil tank, with one end of the oil inlet pipe fixedly connected to the oil extraction pump.

[0009] Furthermore, in order to prevent the filter screen from becoming clogged, a cleaning brush is fixedly connected to one side of the top surface of the transmission tube, with one side of the cleaning brush in close contact with the bottom surface of the filter screen.

[0010] Furthermore, in order to observe the amount of oil in the tank, an oil level gauge is fixedly installed inside the tank.

[0011] Furthermore, in order to release the pressure inside the oil tank, a pressure relief valve is fixedly installed on one side surface of the oil tank.

[0012] Furthermore, in order to remove the residue filtered from the collection tray, a cleaning door is rotatably installed on one side of the collection tray.

[0013] The beneficial effects of the utility model are:

[0014] 1. The drive motor drives the active gear to rotate. The active gear meshes with the driven gear, which in turn drives the transmission pipe and the heat dissipation pipe to rotate on the support frame. After the heat dissipation pipe rotates, it moves relative to the air, causing the outside air to blow onto the surface of the heat dissipation pipe. This achieves rapid air cooling of the transformer oil inside the heat dissipation pipe, reduces the oil temperature in the oil tank, and protects the various components of the high-voltage bay structure.

[0015] 2. While the transformer oil in the tank is cooled by the transmission pipe and the heat dissipation pipe, the transformer oil is drawn into the collection pan by the oil pump. The transformer oil is filtered by the filter screen in the collection pan to prevent sediment and sludge from entering the tank after long-term use and affecting and damaging the various components of the high-voltage bay structure. This effectively reduces safety hazards and maintenance costs. Attached Figure Description

[0024] According to an embodiment of this utility model, a 35KV high-voltage bay structure for transformers is provided.

[0025] Example 1:

[0026] like Figures 1-4As shown, a 35KV high-voltage bay structure for transformers according to an embodiment of this utility model includes a transformer body 1 with a rated voltage of 35KV; an oil tank 2 is fixedly connected to one side of the transformer body 1, and a high-voltage load switch 3 is fixedly installed on one side of the inner wall of the oil tank 2 for opening and closing the circuit and controlling the power supply status of the transformer; a high-voltage fuse 4 is fixedly installed on one side of the high-voltage load switch 3 as an overload and short-circuit protection device, which works in conjunction with the high-voltage load switch 3 to automatically cut off the current when an abnormal current occurs in the circuit; an oil outlet pipe 5 is installed on one side of the bottom of the oil tank 2 for discharging oil during transformer oil circulation and cooling; a transmission pipe 6 is rotatably connected to one end of the oil outlet pipe 5; a support frame 7 is installed on the outer side of the oil tank 2, and a transmission cooling mechanism 8 is fixedly installed on one side of the support frame 7 for driving the transmission pipe 6 to rotate and cooling the transformer oil inside; a collection and filtration mechanism 9 is fixedly installed on the top of the transmission pipe 6 for filtering and collecting sediment and residue generated by the transformer oil; the transmission cooling mechanism 8 includes a transmission... A driven gear 801 is fixedly mounted on the surface of the drive tube 6. A drive motor 802 is fixedly mounted on one side of the support frame 7. A drive gear 803 is fixedly connected to the drive shaft of the drive motor 802. The drive gear 803 meshes with the driven gear 801. A sliding groove 804 is formed on one side of the support frame 7. Multiple heat dissipation pipes 805 are connected around the surface of the drive tube 6. These heat dissipation pipes 805 are supported by thin aluminum sheets and have the function of rapid heat conduction and dissipation. The drive tube 6 and the heat dissipation pipes 805 are internally connected. The heat sink 805 is connected to a universal wheel 806 fixedly installed on one side surface. The universal wheel 806 is slidably installed in the sliding groove 804 to support the rotation of the transmission pipe 6 and the heat sink 805. The drive motor 802 drives the drive gear 803 to rotate, which causes the driven gear 801 to drive the transmission pipe 6 and the heat sink 805 to rotate above the support frame 7. The relative movement between the heat sink 805 and the outside air when it rotates allows the outside air to blow onto the heat sink 805 to quickly dissipate the transformer oil inside.

[0027] like Figures 1-4As shown, the collection and filtration mechanism 9 includes a collection tray 901 rotatably connected to the top of the transmission pipe 6. A filter screen 902 is fixedly installed in the middle of the inner wall of the collection tray 901 for filtering the passing transformer oil. An oil extraction pipe 903 is fixedly connected to the top of the collection tray 901. An oil extraction pump 904 is fixedly installed at one end of the oil extraction pipe 903 for providing pressure to the transmission pipe 6 and the oil extraction pipe 903 to extract the transformer oil from the oil tank 2. An oil inlet pipe 905 is fixedly installed on one side of the top of the oil tank 2. One end of the oil inlet pipe 905 is fixedly connected to the oil extraction pump 904 for re-feeding the cooled and filtered transformer oil back into the oil tank 2. A cleaning brush 10 is fixedly connected to one side of the top surface of the 6. One side of the cleaning brush 10 is in close contact with the bottom surface of the filter screen 902. After the transmission tube 6 rotates, it drives the cleaning brush 10 to brush the bottom surface of the filter screen 902 to prevent the filter screen 902 from becoming clogged. An oil level gauge 11 is fixedly installed inside the oil tank 2 to detect and observe the oil level in the oil tank 2. A pressure relief valve 12 is fixedly installed on one side surface of the oil tank 2. It automatically opens when the pressure in the oil tank 2 rises abnormally to release the internal pressure. A cleaning door 13 is rotatably installed on one side surface of the collection tray 901. After it is rotated open, it is used to clean the impurities filtered and collected in the collection tray 901.

[0028] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0029] In practical applications, the drive motor 802 and the oil pump 904 are started. The oil pump 904 draws the transformer oil in the oil tank 2 into the drive pipe 6 and the cooling pipe 805. The drive motor 802 drives the drive gear 803 to rotate. The drive gear 803, through meshing with the driven gear 801, drives the drive pipe 6 and the cooling pipe 805 to rotate on the support frame 7. After the cooling pipe 805 rotates, it moves relative to the air, causing the outside air to blow onto the surface of the cooling pipe 805, achieving rapid air cooling of the transformer oil inside the cooling pipe 805 and reducing the oil temperature in the oil tank 2. After the transformer oil is cooled by air in the cooling pipe 805, it continues to flow through the drive pipe 6 into the collection tray 901. The filter screen 902 in the collection tray 901 filters and collects the residue. The filtered transformer oil is then drawn by the oil pump 904, enters the oil extraction pipe 903, and then enters the oil tank 2 through the oil inlet pipe 905, completing the cooling and filtration of the transformer oil in the oil tank 2.
