Description

Technical Field

[0001] This utility model relates to the field of outdoor substation technology, and in particular to an outdoor substation with thermal insulation. Background Technology

[0002] An outdoor substation is a substation where the equipment connecting the transmission lines to the substation is located outdoors, typically installed on a steel frame structure or concrete foundation. An outdoor substation consists of transformers, disconnect switches, load switches, instruments, and protection equipment. Its primary function is power transmission and transformation, reducing the voltage of high-voltage transmission lines to a level suitable for delivery to customers. It uses transformers to lower the high voltage to meet the power requirements of various electrical devices. Furthermore, outdoor substations also have protection and control functions to ensure the safe and stable operation of the power system.

[0003] However, existing outdoor substations do not have insulation functions during use, which makes their internal components prone to freezing and damage in the cold winter, reducing their insulation efficiency. Furthermore, the sealing plates cannot be effectively adjusted, which prevents effective ventilation and heat dissipation in the hot summer, reducing their ventilation efficiency. Therefore, we propose an outdoor substation with insulation. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide an outdoor substation with heat preservation function, which can prevent its internal components from freezing in the cold winter weather, thereby improving its heat preservation efficiency, and can effectively adjust the sealing plate to enable effective ventilation and heat dissipation in the hot summer weather, thereby improving its ventilation efficiency.

The first insulation board 10 has a first air guide groove 8, and the second insulation board 18 has a second air guide groove 13. An air inlet pipe 16 connects the upper second air guide groove 13 to the cabinet body 7, and duct pipes 17 connect the inner walls of the upper second air guide groove 13 to the two first air guide grooves 8, respectively. Several evenly distributed air outlets 9 are provided near the bottom of the inner wall of the heat preservation cabinet 1, where the first air guide grooves 8 and the inner wall of the heat preservation cabinet 1 are located.

[0022] Ventilation windows 21 are provided on both the left and right sides near the top of the cabinet 1, and a first dustproof net 23 is bolted to the ventilation windows 21. L-shaped plates 5 are attached to both the left and right sides near the top of the cabinet 1, and a horizontal plate 6 is bolted to the bottom of the L-shaped plates 5. A shell 3 is bolted to the outer walls of both sides of the cabinet 1 near the bottom, and an electric push rod 4 is bolted to the bottom of the inner cavity of the shell 3. A through hole is provided at the top of the inner cavity of the shell 3, and the top of the electric push rod 4 passes through the through hole and connects to the bottom of the horizontal plate 6. This structure enables the cabinet to have a heat preservation function, thus preventing the internal components from freezing in cold winter weather and improving its heat preservation efficiency.

[0023] Ventilation pipes 19, corresponding to ventilation windows 21, are bolted to the inner walls of the left and right sides of the heat preservation cabinet 1 near the top. The side of the ventilation pipe 19 away from the inner wall of the heat preservation cabinet 1 passes through the first insulation board 10 and the outer wall of the cabinet body 7, and is connected to the interior of the cabinet body 7. A second dustproof net 24 is bolted to the side of the ventilation pipe 19 away from the first dustproof net 23. A sealing plate 22 is installed inside the ventilation pipe 19 on the side away from the second dustproof net 24, and the sealing plate 22 is attached to the side wall of the first dustproof net 23. A through groove matching the sealing plate 22 is opened at the top of the inner cavity of the ventilation pipe 19, and the top of the sealing plate 22... The cabinet 1 is bolted to a connecting plate 20. A through hole matching the connecting plate 20 is opened at the top of the inner cavity of the cabinet 1, and the top of the connecting plate 20 passes through the through hole and connects to the bottom of the L-shaped plate 5. Push plates 11 are slidably connected to the lower second air guide duct 13 near the left and right sides, respectively. A double-headed electric cylinder 12 is bolted to the middle of the second air guide duct 13, and the push rods on both sides of the double-headed electric cylinder 12 are respectively connected to the side walls of the two push plates 11. Round pipes 14 are connected to the top of the lower second air guide duct 13 near the left and right sides, and the top of the round pipes 14 are connected to the interior of the cabinet 7. This structure allows for effective adjustment of the sealing plate 22, enabling effective ventilation and heat dissipation in hot summer weather, thus improving its ventilation efficiency.

[0024] Working Principle: In use, the insulation cabinet 1 and cabinet body 7 are first placed in the desired positions. Then, the cabinet door 2 is opened, and the transformer, disconnector, load switch, instruments, and protection equipment are installed on the mounting plate 15. The cabinet door 2 is then closed. When the cabinet generates heat, the heat is introduced into the upper second air guide duct 13 through the air inlet pipe 16. The second air guide duct 13 then guides the hot air to the first air guide ducts 8 on both sides through the duct 17. The first air guide ducts 8 then guide the hot air into the insulation cabinet 1 through the air outlet 9. Due to the sealing of the L-shaped plate 5 and the sealing plate 22, the hot air is retained inside the insulation cabinet 1, enabling it to maintain its heat. This prevents the internal components from freezing in cold winter weather, thus improving its performance. The insulation efficiency is improved by the extension and retraction of the electric push rod 4, which can drive the L-shaped plate 5 to move upward or to the left through the horizontal plate 6, causing the L-shaped plate 5 to fall off or fit against the ventilation window 21. At the same time, the L-shaped plate 5 drives the sealing plate 22 to move upward or downward through the docking plate 20, causing the sealing plate 22 to move out of or into the ventilation pipe 19. The extension and retraction of the push rods on both sides of the double-headed electric cylinder 12 drives the two push plates 11 to move left and right in the second air guide groove 13 below, so that the round pipe 14 blows air to the cabinet 7. The hot air in the insulation cabinet 1 can be discharged through the ventilation window 21. The hot air in the cabinet 7 can be discharged through the ventilation pipe 19 and the ventilation window 21, which can effectively adjust the sealing plate 22, so that it can effectively ventilate and dissipate heat in hot summer weather, thus improving its ventilation efficiency.

[0025] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
