Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage cabinets, in particular to a multifunctional high-voltage cabinet. Background Art

[0002] High-voltage cabinets are key equipment used to distribute, control, and protect electrical energy within power systems. They are primarily used in substations, industrial and mining enterprises, power plants, and other locations, where they receive, distribute, and transmit high-voltage power. Through internal components such as circuit breakers, disconnectors, transformers, and protective devices, they control circuit on / off, distribute loads, and provide rapid protection against faults like short circuits and overloads, ensuring the safe and stable operation of the power system.

[0003] Enclosed gas-filled high-voltage switchgear is commonly used in areas with limited space or harsh environments (such as humidity, dust, and high altitude), such as urban substations, industrial and mining enterprises, rail transit, and data centers. This type of switchgear uses insulating gas (such as sulfur hexafluoride SF6, nitrogen, or a mixed gas) as arc extinguishing and insulating medium. Its sealed design effectively isolates the external environment, preventing contaminants such as moisture and dust from affecting internal components, ensuring reliable operation of the equipment under high voltage conditions (such as 10kV, 35kV, and above).

[0004] The existing enclosed inflatable high-voltage cabinets have gradually exposed their shortcomings during use, mainly in the following aspects:

[0005] The interior of a closed inflatable high-voltage cabinet is a closed space. During operation, a large amount of heat is generated due to the high load current, which causes the temperature to continue to rise, and then causes a series of problems such as deterioration of insulation materials, increased contact resistance, deformation of mechanical structures and decreased gas sealing performance, which seriously threatens the reliability and service life of the equipment. Although this type of high-voltage cabinet currently uses high thermal conductivity materials to make the cabinet body and cooperates with external fans to force heat dissipation to enhance gas flow in key areas, its heat dissipation mechanism still relies on the heat to be slowly conducted through the cabinet material to the outer surface for release. This passive heat dissipation method has inherent defects such as long heat conduction path, high thermal resistance and low heat dissipation efficiency, which makes it difficult to effectively discharge the heat accumulated inside the cabinet body. It is in a high-temperature operation state for a long time, which not only accelerates the aging process of components, but also greatly increases the risk of failure.

[0006] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Summary of the Invention

[0007] In response to the defects in the prior art, the technical problem to be solved by the present invention is to provide a multifunctional high-voltage cabinet, which has the effect of pressurizing to compensate for the heat exchange efficiency, has a fast heat dissipation speed, and the interior of the cabinet is always kept at a low temperature. In addition, the heat dissipation mode of the high-voltage cabinet can be dynamically adjusted according to actual working conditions.

[0008] In order to solve the above problems, the present invention provides the following technical solutions:

[0009] The vents are connected to the air intake passage and the exhaust passage are connected to the exhaust passage. The vents are connected to the air intake passage and the exhaust passage are connected to the exhaust passage.

[0010] As an optimized solution, the one-way air intake assembly includes a labyrinth piston that is slidably and sealingly connected to the connecting pipe. The outer wall of the cabinet is provided with a plurality of air intake grooves that are connected to the air intake channel. An air intake one-way valve is fixedly installed at the port of the air intake groove. A plurality of air vents are penetrated at the end of the labyrinth piston. An exhaust one-way valve is fixedly installed at the port of the air vent.

[0011] A drive plate is provided in the cooling box for horizontal reciprocating sliding. The labyrinth piston is fixedly connected to the drive plate via a connecting rod. The rotating circular plate is connected to the drive plate via a one-way transmission assembly.

[0012] The transmission gear of claim 1, wherein the first gear and the second gear are connected along the longitudinal axis of the gear shift shaft to form a rotation between the gear shift pins and the gear shifter, the rotation between the gear shift pins that engage with the gear shift pins in the forward direction and the reverse direction.

[0013] As an optimized solution, water tanks are provided at the top and bottom of the cooling box, and the two ports of the heat exchange tube extend through the water tank to the outside. An annular groove is provided on the outer wall of the heat exchange tube located inside the water tank, and a plurality of water holes are provided inside the heat exchange tube. The two ports of the water holes are connected to the two annular grooves respectively, and the two water tanks are connected to the circulating cooling water source.

[0014] As an optimized solution, fins are fixedly connected to the outer wall of the heat exchange tube at a position inside the cooling box.

[0015] As an optimized solution, a mounting plate is fixedly provided at the end of the cabinet, and a cooling fan is fixedly installed on the top of the mounting plate.

[0016] As an optimized solution, a driving telescopic cylinder is fixedly provided at the end of the cooling box, and the telescopic end of the driving telescopic cylinder extends into the cooling box and is fixedly connected to the driving plate.

[0017] As an optimized solution, the top and bottom of the driving plate are correspondingly slidably connected to the inner top and inner bottom of the cooling box.

[0018] As an optimized solution, both ends of the connecting pipe are detachably connected to the cabinet and the cooling box respectively, the fixing column is detachably connected to the cabinet, and the open end of the connecting box is detachably connected to the cooling box.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. When the interior of the cabinet is cooled, the telescopic cylinder drives the driving plate to slide back and forth horizontally, thereby driving the labyrinth piston to slide back and forth horizontally. When the labyrinth piston slides toward the cooling box, the air pressure in the space on the left side of the connecting pipe decreases, and the gas inside the cabinet enters the connecting pipe in one direction through the air inlet hole, the air inlet channel, the air inlet groove and the air inlet one-way valve. When the labyrinth piston slides toward the cabinet, the air pressure in the space on the left side of the connecting pipe increases, and the gas in the space on the left side of the connecting pipe enters the cooling box in one direction through the air vent and the exhaust one-way valve. Under the blowing of the cooling fan, the external air continuously passes through the heat exchange tube, and the gas in the cooling box exchanges heat with the external flowing gas through the heat exchange tube and is cooled. During the horizontal reciprocating sliding of the driving plate, it also drives the driving rack to move back and forth horizontally. When the driving rack moves toward the cooling box, the active end face ratchet rotates under the transmission of the driven gear, the active bevel gear and the driven bevel gear. At this time, the driven end face ratchet does not transmit, and the rotating circular plate is stationary. When the driving rack moves toward the cabinet body, the active end face ratchet rotates in the opposite direction, and the driven end face ratchet transmits, thereby driving the rotating circular plate to rotate. This reciprocating process occurs. When the edge hole and the connecting hole are not connected, the gas in the cooling box gradually increases, and the air pressure in the cooling box increases. The heat exchange rate of the high-pressure gas is higher than that of the low-pressure gas. Therefore, the heat exchange rate of the pressurized gas in the cooling box is faster, and the heat dissipation efficiency is higher. The high-pressure cabinet has the effect of pressurization compensating the heat exchange efficiency, the heat dissipation speed is fast, and the inside of the cabinet is always kept at a low temperature.

[0021] 2. As the rotating circular plate rotates, the edge holes are connected to the connecting holes, and the gas in the cooling box enters the cabinet through the exhaust channel and the exhaust holes. The mode of extracting air on one side and exhausting air on the other side can form a horizontal wind in the interior space of the cabinet, thereby better dissipating heat to the internal components.

[0022] 3. When excessive heat accumulates inside the cabinet and the cooling fan cannot meet the heat dissipation demand, the circulating cold water source is turned on. Cold water enters the water tank below, flows upward through the annular groove into the water hole and enters the water tank above. The cold water in the upper water tank is recovered to the circulating cold water source. When the cold water passes through the heat exchange tubes, it cools the heat exchange tubes, thereby accelerating the cooling speed of the gas in the cooling box, ensuring that the temperature inside the high-voltage cabinet remains within the normal range. The heat dissipation mode of the high-voltage cabinet can be dynamically adjusted according to the actual working conditions, which improves practicality.

[0023] 4. The labyrinth piston has the characteristics of low friction and no lubrication. Low friction can effectively reduce frictional heat, and no lubrication can prevent the lubricating oil from polluting the internal gas;

[0024] 5. The fins on the heat exchange tubes can effectively improve the heat exchange efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] A mounting plate 3 is fixedly mounted on the end of the cabinet 1 , and a cooling fan 4 is fixedly mounted on the top of the mounting plate 3 .

[0045] A driving telescopic cylinder 21 is fixedly provided at the end of the cooling box 5 . The telescopic end of the driving telescopic cylinder 21 extends into the cooling box 5 and is fixedly connected to the driving plate 22 .

[0046] The top and bottom of the driving plate 22 are correspondingly slidably connected to the inner top and inner bottom of the cooling box 5 .

[0047] Two ends of the communication pipe 15 are detachably connected with the cabinet body 1 and the cooling box 5, the fixing column 20 is detachably connected with the cabinet body 1, and the opening end of the communication box 19 is detachably connected with the cooling box 5.

[0048] The working principle of the device is as follows:

[0049] When the cabinet body 1 is cooled, the telescopic cylinder 21 drives the driving plate 22 to slide horizontally and reciprocally, and then drives the labyrinth piston 14 to slide horizontally and reciprocally. When the labyrinth piston 14 slides to the cooling box 5, the air pressure in the left space of the communication pipe 15 decreases, and the air in the cabinet body 1 enters the communication pipe 15 through the air inlet hole 11, the air inlet channel 8, the air inlet groove 12 and the air inlet one-way valve 13. When the labyrinth piston 14 slides to the cabinet body 1, the air pressure in the left space of the communication pipe 15 increases, and the air in the left space of the communication pipe 15 enters the cooling box 5 through the air hole 24 and the air outlet one-way valve 25. Under the blowing of the cooling fan 4, the external air continuously passes through the heat exchange pipe 7, and the air in the cooling box 5 exchanges heat with the external flowing air through the heat exchange pipe 7 to be cooled. In the process of horizontal reciprocating sliding of the driving plate 22, the driving rack 26 also moves horizontally and reciprocally. When the driving rack 26 moves to the cooling box 5, the driving end face ratchet 32 rotates under the transmission of the driven gear 27, the driving bevel gear 29 and the driven bevel gear 30. At this time, the driven end face ratchet 33 does not transmit, and the rotating circular plate 40 is stationary. When the driving rack 26 moves to the cabinet body 1, the driving end face ratchet 32 rotates reversely, the driven end face ratchet 33 transmits, and then drives the rotating circular plate 40 to rotate. In this way, when the edge hole 36 is not communicated with the communication hole 35, the air in the cooling box 5 gradually increases, the air pressure in the cooling box 5 increases, and the heat exchange speed of the high-pressure gas is higher than that of the low-pressure gas. Therefore, the heat exchange speed of the air in the cooling box 5 after pressurization is faster, the heat dissipation efficiency is higher, the high-pressure cabinet has the effect of pressurization compensation heat dissipation efficiency, the heat dissipation speed is fast, and the cabinet body 1 is always kept in a low-temperature state.

[0050] With the rotation of the rotating circular plate 40, when the edge hole 36 is communicated with the communication hole 35, the air in the cooling box 5 enters the cabinet body 1 through the air outlet channel 9 and the air outlet hole 10. Through the mode of one side air extraction and the other side air exhaust, the space in the cabinet body 1 can form a transverse through wind, which can better cool the internal devices;

[0051] When too much heat accumulates inside the cabinet 1 and the cooling fan 4 cannot meet the heat dissipation demand, the circulating cold water source is turned on, and the cold water enters the water tank 6 below. The cold water enters the water through hole 43 through the annular groove 44 and flows upward and enters the water tank 6 above. The cold water in the upper water tank 6 is recovered to the circulating cold water source. When the cold water passes through the heat exchange tube 7, it cools the heat exchange tube 7, thereby accelerating the cooling speed of the gas in the cooling box 5, ensuring that the temperature in the high-voltage cabinet is kept within a normal range. The heat dissipation mode of the high-voltage cabinet can be dynamically adjusted according to the actual working conditions, thereby improving practicality.

[0052] The labyrinth piston 14 has the characteristics of low friction and no lubrication. Low friction can effectively reduce frictional heat, and no lubrication can prevent the lubricating oil from contaminating the internal gas.

[0053] The fins 42 on the heat exchange tubes 7 can effectively improve the heat exchange efficiency.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or make equivalent replacements for some or all of the technical features therein.
