Description

Technical Field

[0001] This invention relates to the field of recloser technology, specifically an insulating and temperature-monitoring recloser. Background Technology

[0002] A recloser is an intelligent switching device used in power distribution network automation. It has its own control and protection functions, can automatically detect fault current passing through the main circuit, disconnect the fault current within a given time, and can automatically perform opening and reclosing operations in AC lines according to a pre-set opening and reclosing sequence. After the operation, it automatically resets or locks out. The recloser is similar to a regular circuit breaker in terms of breaking performance, but it has the function of multiple reclosing. It is widely used in high-voltage transmission and distribution lines of power systems. In existing reclosers, the internal electrical components generate a lot of heat during long-term operation. When the heat inside the recloser is not effectively dissipated, it will cause the components to age faster, thus affecting the service life and operational reliability of the recloser. Traditional heat dissipation methods usually involve introducing outside air for air cooling. However, when the humidity increases, the moisture in the outside air will be carried into the recloser casing, causing the internal humidity to rise. This not only affects the insulation performance of the electrical components but may also cause safety hazards such as short circuits. Summary of the Invention

[0003] The purpose of this invention is to provide an insulating and temperature-monitoring recloser to solve the heat dissipation and cooling problems existing in the prior art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: An insulating and temperature-monitoring recloser includes a housing and several poles, with the poles disposed on the top of the housing. A heat dissipation assembly is disposed on the side wall of the housing, and a temperature sensor is disposed inside the housing. The heat dissipation assembly consists of two delivery pipes. The delivery pipe includes a connecting cavity, a gas delivery end, and a connecting pipe. The connecting cavity is located in the middle of the long side of the outer shell. A connecting pipe is installed between the connecting cavity and the outer shell. The connecting cavity is connected to the inside of the outer shell through the connecting pipe. The connecting cavity is connected to the gas delivery end. An air pump is installed in the connecting cavity. The air pump is connected to the gas delivery end through a pipe. Cooling pipes are provided at both ends of the connecting cavity, and the connecting cavity is connected to the cooling pipes. A return pipe is provided at the end of the cooling pipe away from the connecting cavity. One end of the return pipe is connected to the short side of the outer shell, and the other end of the return pipe is connected to the cooling pipe.

[0005] When cooling of the interior of the casing is required, the controller activates the air pump, which draws in outside air. This outside air is then delivered through the air inlet to the connecting cavity, and from there to the connecting pipe. Since the connecting cavity is located in the middle of the long side of the casing, outside air enters from the center of the casing and is then distributed to both ends, thus splitting the airflow in the middle of the casing. This cooling effect is achieved by facilitating heat dissipation for the electrical components near the sides, thereby improving the internal cooling efficiency of the casing. When outside air is delivered to the side of the casing near the return pipe, it flows from the inside of the casing into the return pipe. Because the two return pipes are connected, outside air flows to... Two return pipes supply air, which is a second round of diversion. The diverted outside air is then transported from the return pipes to the cooling pipes, where it undergoes heat exchange and cooling. The cooled outside air is then transported back to the connecting cavity through the cooling pipes, where it is again transported to the outer casing for further cooling. After the air pump has drawn outside air for a period of time, the air supply end is closed, allowing the drawn outside air to circulate between the outer casing, return pipes, cooling pipes, connecting cavity, and connecting pipes. This prevents the introduction of highly humid outside air into the outer casing, thus avoiding interference with the electrical components inside and ensuring the normal operation of the recloser.

[0006] Preferably, a rotating assembly is provided on the side of the connecting pipe near the outer shell. The rotating assembly includes a rotating ring, a support block is provided in the middle of the rotating ring, the support block is connected to the rotating ring by a bracket, and a plurality of rotating plates are provided between the support block and the rotating ring. The plurality of rotating plates are arranged around the axis of the rotating ring, and the rotating plates are rotatably connected to the rotating ring and the support block respectively. A driving mechanism is provided inside the rotating ring, and the driving mechanism drives the rotating shaft of the rotating plate to rotate.

[0007] The drive mechanism starts the rotating plate and drives its shaft to rotate, causing the rotating plate to deflect. This creates a gap between adjacent rotating plates. By adjusting the angle of rotation, the distance between adjacent rotating plates can be adjusted, thereby regulating the amount of outside air entering the casing. When the vertical plane of the rotating plate after deflection forms an angle with the axis of the connecting pipe, the outside air flowing through the adjacent rotating plates will push the rotating plates to rotate. As a result, several rotating plates will revolve around the axis of the support block, causing the rotating plate to drive the rotating ring to rotate. This allows outside air to be quickly transported into the interior of the casing, thereby improving the heat dissipation effect inside the casing.

[0008] Preferably, a deflection group is provided at one end of the cooling pipe near the connecting cavity. The deflection group consists of several deflection claws, which are arranged around the axis of the cooling pipe. The deflection claws are rotatably connected to the inner wall of the connecting cavity through a rotating shaft. A power component is provided on the inner wall of the connecting cavity, and the power component drives the rotating shaft of the deflection claws to rotate.

[0009] During the circulating heat dissipation phase, several deflection claws are in a separated state, so that two adjacent deflection claws do not contact each other. At this time, the cooling pipe and the connecting cavity are in a connected state. When a fire occurs due to a malfunction of the electrical components inside the casing, the temperature sensor inside the casing detects the internal temperature. If a rapid temperature rise is detected, the controller activates the power unit, which drives the shaft of the deflector claws to rotate. This causes several deflector claws to rotate towards the side closest to the cooling pipe axis, and then the deflector claws close together. Simultaneously, the controller activates the air pump to draw air outwards, extracting air from inside the casing. This air is then transported through the connecting pipe to the connecting cavity, and finally output to the air supply end through the connecting cavity. Meanwhile, the air in the cooling pipe is transported to the return pipe, and then from the return pipe back into the casing. Because the air temperature in the cooling pipe is lower, this lower temperature helps to cool the internal temperature of the casing. Furthermore, the air pump's extraction of air from the casing and cooling pipe reduces the oxygen content inside the casing, resulting in a lower content of oxidizer, thereby suppressing the fire of the electrical components inside the casing.

[0010] Preferably, the outer wall of the cooling pipe is provided with a plurality of cooling fins, the cooling fins extending into the inner tube of the cooling pipe, and the spacing between the cooling fins on the side closer to the outer wall is greater than the spacing between the cooling fins on the side closer to the inner tube.

[0011] After the outside air inside the outer shell enters the cooling pipe through the return pipe, it is divided into several sections by several cooling fins on the outer wall of the cooling pipe that extend into the inner tube of the cooling pipe. As a result, the outside air is diverted again after entering the cooling pipe, so that the outside air is transported between two adjacent cooling fins. The outside air flows between the two cooling fins and comes into contact with the opposite side of the two cooling fins during the flow. This allows the outside air flowing through the cooling pipe to exchange heat with the outside air. As a result, when the outside air is transported from the cooling pipe to the connecting cavity, the temperature of the outside air inside the cooling pipe is lower than the temperature of the outside air inside the outer shell.

[0012] Preferably, in the circulating cooling stage, the air inside the outer shell is transported to the return pipes at both ends, then to the cooling pipes, where it is cooled down. The air is then collected in the connecting cavity by the cooling pipes, and subsequently transported to the connecting pipes through the connecting cavity, and finally re-enters the outer shell through the connecting pipes.

[0013] Preferably, the cooling pipe is further provided with a plurality of fixing rings, which are arranged at equal intervals along the axis of the cooling pipe.

[0014] By setting several fixing rings, the cross-section of the cooling pipe's delivery channel is further compressed. With the cooperation of the fixing rings and cooling fins, the contact area between the gas inside the cooling pipe and the inner wall is increased, thereby further improving the efficiency of gas cooling and heat exchange inside the cooling pipe. Thus, the recloser's cooling and heat dissipation are achieved without introducing external gas to participate in the heat dissipation inside the shell. Furthermore, when the gas flows between the fixing rings and the inner wall of the cooling pipe, the gas velocity is further increased, thereby improving the efficiency of gas cooling and heat exchange.

[0015] Preferably, the cross-sections of the connecting cavity, the gas delivery end, and the connecting pipe are arranged at right angles.

[0016] Because the cross-sections of the connecting cavity, the air supply end, and the connecting pipe are arranged at right angles, the axis of the air supply end is perpendicular to the ground, while the axis of the connecting pipe is parallel to the ground, and the air supply end faces the ground. This ensures that in rainy weather, the air supply end is located at the bottom of the connecting cavity, thus preventing rainwater from entering the air supply end. Otherwise, rainwater would enter the connecting cavity through the air supply end, and during the subsequent heat dissipation and cooling process, the air would carry the rainwater into the outer casing, thereby affecting the electrical components inside the casing. This further improves the operational stability of the recloser.

[0017] Preferably, the diameter of the cooling pipe is smaller than the diameter of the connecting cavity and the return pipe.

[0018] Because the diameter of the cooling pipe is smaller than that of the connecting cavity and the return pipe, the gas in the return pipe is transported to the cooling pipe. When the gas enters the cooling pipe, the change in the diameter of the cooling pipe reduces the cross-section of the air transport channel, thus increasing the air velocity in the cooling pipe. Furthermore, the cooling pipe is equipped with several cooling fins, which work together with the reduced-diameter cooling pipe to achieve rapid cooling of the gas. By circulating and cooling the gas inside the casing, the system prevents high-humidity external gas from entering the casing and participating in the heat dissipation and cooling process. This avoids increased humidity inside the casing, which could damage the electrical components inside, thus ensuring the normal operation of the recloser.

[0019] Compared with the prior art, the beneficial effects of the present invention are: The delivery system includes a connecting cavity, a gas delivery end, and a connecting pipe. The connecting cavity is located in the middle of the long side of the outer shell and connects to the interior of the outer shell via the connecting pipe. Cooling pipes are installed at both ends of the connecting cavity. The end of the cooling pipe furthest from the connecting cavity is connected to the short side of the outer shell via a return pipe. During heat dissipation and cooling, the air pump draws in outside air and sends it into the connecting cavity through the gas delivery end. Then, it is introduced into the interior from the middle of the outer shell through the connecting pipe and delivered to both ends, achieving gas diversion and effectively improving the heat dissipation efficiency of the electrical components on both sides of the outer shell. Subsequently, the gas is delivered to the cooling pipes through the return pipe, where it undergoes heat exchange and cooling before returning to the connecting cavity and circulating back into the outer shell. After the air pump draws in outside air for a period of time, the gas delivery end is closed, forming a closed loop of gas between the outer shell, return pipe, cooling pipe, connecting cavity, and connecting pipe. This effectively prevents moisture from entering the interior of the outer shell when the external humidity is high. This ensures the insulation performance and service life of the electrical components inside the recloser. At the same time, the diameter of the cooling pipe is smaller than that of the connecting cavity and the return pipe. After the gas in the return pipe enters the cooling pipe, the cross-section of the delivery channel becomes smaller and the air velocity increases. With the help of multiple cooling fins extending into the inner tube and fixed rings equidistantly arranged along the axis of the cooling pipe, the cooling fins divide the cooling pipe into several partitions, and the fixed rings further compress the cross-section of the delivery channel, increasing the contact area between the gas and the inner wall of the cooling pipe and improving the cooling heat exchange efficiency of the gas in the cooling pipe. This enables the recloser to be circulated and cooled without introducing external gas to participate in heat dissipation. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figure 1 The first embodiment of the present invention shown is an insulating and disconnected temperature monitoring recloser, which includes a housing 1 and a plurality of pole posts 11. The plurality of pole posts 11 are disposed on the top of the housing 1. A heat dissipation assembly 2 is disposed on the side wall of the housing 1. A temperature sensor is disposed inside the housing 1. The heat dissipation assembly 2 is composed of two delivery pipes 21. The delivery pipe 21 includes a connecting cavity 22, a gas delivery end 23, and a connecting pipe 24. The connecting cavity 22 is located in the middle of the long side of the outer shell 1. The connecting pipe 24 is installed between the connecting cavity 22 and the outer shell 1. The connecting cavity 22 is connected to the inside of the outer shell 1 through the connecting pipe 24. The connecting cavity 22 is connected to the gas delivery end 23. An air pump is installed in the connecting cavity 22. The air pump is connected to the gas delivery end 23 through a pipe. Cooling pipes 25 are provided at both ends of the connecting cavity 22, and the connecting cavity 22 is connected to the cooling pipes 25. A return pipe 26 is provided at the end of the cooling pipe 25 away from the connecting cavity 22. One end of the return pipe 26 is connected to the short side of the outer shell 1, and the other end of the return pipe 26 is connected to the cooling pipe 25.

[0024] In one specific embodiment of the present invention, during the circulating cooling stage, the air inside the outer shell 1 is transported to the two end return pipes 26, then to the cooling pipe 25, where it is cooled down. The air is then collected in the connecting cavity 22 through the cooling pipe 25, and subsequently transported to the connecting pipe 24 through the connecting cavity 22, and finally re-enters the outer shell 1 through the connecting pipe 24.

[0025] In one specific embodiment of the present invention, the cross-sections of the connecting cavity 22, the gas supply end 23 and the connecting pipe 24 are arranged at right angles.

[0026] In one specific embodiment of the present invention, the diameter of the cooling pipe 25 is smaller than the diameter of the connecting cavity 22 and the return pipe 26.

[0027] like Figures 2-9 The second embodiment of the present invention shown provides a delivery pipe 21 that is different from that of the first embodiment. The difference is that in this embodiment, a rotating assembly 27 is provided in the connecting pipe 24, and a deflection assembly 28 and a cooling plate 251 are provided in the cooling pipe 25. When the recloser is in the circulating cooling stage, the air flows sequentially through the connecting cavity 22, the connecting pipe 24, the inside of the outer shell 1, the return pipe 26, the cooling pipe 25, and the connecting cavity 22, thereby achieving circulating heat dissipation. When a fire occurs inside the outer shell 1, the deflection assembly 28 closes, so that the air can only flow sequentially through the cooling pipe 25, the return pipe 26, the inside of the outer shell 1, the connecting pipe 24, and the connecting cavity 22, thereby achieving unidirectional output.

[0028] The specific content is as follows: In one specific embodiment of the present invention, a rotating assembly 27 is provided on the side of the connecting pipe 24 near the outer shell 1. The rotating assembly 27 includes a rotating ring 271, and a support block 272 is provided in the middle of the rotating ring 271. The support block 272 and the rotating ring 271 are connected by a bracket. A plurality of rotating plates 273 are provided between the support block 272 and the rotating ring 271. The plurality of rotating plates 273 are arranged around the axis of the rotating ring 271. The rotating plates 273 are rotatably connected to the rotating ring 271 and the support block 272 respectively. A driving mechanism is provided inside the rotating ring 271, and the driving mechanism drives the rotating shaft of the rotating plate 273 to rotate.

[0029] In one specific embodiment of the present invention, a deflection group 28 is provided at one end of the cooling pipe 25 near the connecting cavity 22. The deflection group 28 is composed of a plurality of deflection claws 281, which are arranged around the axis of the cooling pipe 25. The deflection claws 281 are rotatably connected to the inner wall of the connecting cavity 22 through a rotating shaft. A power component is provided on the inner wall of the connecting cavity 22, and the power component drives the rotating shaft of the deflection claws 281 to rotate.

[0030] In one specific embodiment of the present invention, a plurality of cooling fins 251 are provided on the outer wall of the cooling pipe 25. The cooling fins 251 extend into the inner tube of the cooling pipe 25, and the spacing of the cooling fins 251 near the outer wall is greater than the spacing of the cooling fins 251 near the inner tube.

[0031] In one specific embodiment of the present invention, a plurality of fixing rings 252 are also provided inside the cooling pipe 25, and the plurality of fixing rings 252 are arranged at equal intervals along the axis of the cooling pipe 25.

[0032] Working principle of the invention: When cooling of the interior of the outer casing 1 is required, the controller activates the air pump, which draws in outside air. This outside air is then delivered through the air inlet 23 to the connecting cavity 22, and from there to the connecting pipe 24. Since the connecting cavity 22 is located in the middle of the long side of the outer casing 1, outside air enters from the middle of the casing 1 and is then distributed to both ends. This splits the airflow in the middle of the casing 1 and improves the cooling efficiency of the electrical components near the sides. When outside air reaches the side of the outer casing 1 near the return pipe 26, it flows from inside the casing 1 into the return pipe 26. Because the two return pipes 26 are connected, outside air... Air is delivered to two return pipes 26, which is a second splitting process. The split outside air is delivered to the cooling pipe 25 through the return pipe 26, where it undergoes heat exchange and cooling. The cooled outside air is then delivered back to the connecting cavity 22 through the cooling pipe 25, where it is delivered back to the outer casing 1 for further cooling. After the air pump has drawn outside air for a period of time, the air delivery end 23 is closed, allowing the drawn outside air to circulate between the outer casing 1, the return pipe 26, the cooling pipe 25, the connecting cavity 22, and the connecting pipe 24. This prevents the introduction of high humidity outside air into the outer casing 1, which could affect the electrical components inside the outer casing 1, especially when the outside humidity is high. During the circulating heat dissipation stage, the drive mechanism is activated, which drives the rotating shaft of the rotating plate 273 to rotate, causing the rotating plate 273 to deflect. This creates a gap between two adjacent rotating plates 273. By adjusting the rotation angle of the rotating plate 273, the distance between two adjacent rotating plates 273 is adjusted, thereby adjusting the amount of airflow into the outer casing 1. When the vertical plane of the rotating plate 273 after deflection forms an angle with the axis of the connecting pipe 24, the outside air flowing through the two adjacent rotating plates 273 will push the rotating plate 273 to rotate. As a result, several rotating plates 273 will revolve around the axis of the support block 272, causing the rotating plate 273 to drive the rotating ring 271 to rotate, allowing the outside air to be quickly transported into the interior of the outer casing 1. Furthermore, several deflection claws 281 are in a separated state, so that two adjacent deflection claws 281 do not contact each other. At this time, the cooling pipe 25 and the connecting cavity 22 are in a connected state. After the outside air inside the outer casing 1 enters the cooling pipe 25 through the return pipe 26, the cooling pipe 25 is divided into several sections by several cooling fins 251 on its outer wall, which extend into the inner tube of the cooling pipe 25. Thus, the outside air is diverted again after entering the cooling pipe 25, so that the outside air is transported between two adjacent cooling fins 251. The outside air flows between the two cooling fins 251 and comes into contact with the opposite side of the two cooling fins 251 during the flow, so that the outside air flowing through the cooling pipe 25 exchanges heat with the outside air. As a result, when the outside air is transported from the cooling pipe 25 to the connecting cavity 22, the temperature of the outside air inside the cooling pipe 25 is lower than the temperature of the outside air inside the outer casing 1. By setting several fixing rings 252, the cross-section of the conveying channel of the cooling pipe 25 is further compressed. With the cooperation of the fixing rings 252 and the cooling fins 251, the contact area between the gas in the cooling pipe 25 and the inner wall is increased, thereby further improving the efficiency of gas cooling and heat exchange in the cooling pipe 25. Thus, the recloser is cooled and dissipated without introducing external gas to participate in the heat dissipation inside the outer shell 1. Furthermore, the gas flow rate is further accelerated when the gas flows between the fixing rings 252 and the inner wall of the cooling pipe 25. Because the diameter of the cooling pipe 25 is smaller than that of the connecting cavity 22 and the return pipe 26, the gas in the return pipe 26 is transported to the cooling pipe 25. When the gas enters the cooling pipe 25, it is affected by the change in the diameter of the cooling pipe 25, which makes the cross-section of the air transport channel smaller. As a result, the air velocity in the cooling pipe 25 increases. Furthermore, the cooling pipe 25 is equipped with several cooling fins 251, which work together with the reduced diameter cooling pipe 25 to achieve rapid cooling of the gas. By circulating and cooling the gas inside the outer casing 1, the high humidity of the outside gas is prevented from entering the outer casing 1 to participate in the heat dissipation and cooling process. This prevents the humidity inside the outer casing 1 from increasing and causing damage to the electrical components inside the outer casing 1, thus ensuring the normal operation of the recloser. When a fire occurs due to a malfunction of the electrical components inside the casing 1, the temperature sensor inside the casing 1 detects the temperature inside the casing 1. If a rapid temperature rise is detected, the controller activates the power assembly, which drives the shaft of the deflection claw 281 to rotate. This causes several deflection claws 281 to rotate towards the side closer to the axis of the cooling pipe 25, and then the several deflection claws 281 close together. The controller also controls the air pump to draw air outward, causing the air pump to extract air from inside the casing 1. This air is then transported through the connecting pipe 24 to the connecting cavity 22, and finally output to the air supply end 23 through the connecting cavity 22. Meanwhile, the air in the cooling pipe 25 is transported to the return pipe 26, and then from the return pipe 26 back into the casing 1. Since the air temperature in the cooling pipe 25 is lower, the lower temperature air can have a certain cooling effect on the temperature inside the casing 1. Furthermore, after the air pump extracts air from the casing 1 and the cooling pipe 25, the oxygen content inside the casing 1 decreases, resulting in a lower content of oxidizer, thereby suppressing the fire of the electrical components inside the casing 1. Because the cross-sections of the connecting cavity 22, the air supply end 23, and the connecting pipe 24 are arranged at right angles, the axis of the air supply end 23 is perpendicular to the ground, while the axis of the connecting pipe 24 is parallel to the ground. Furthermore, the air supply end 23 faces the ground, ensuring that in rainy weather, it is located at the bottom of the connecting cavity 22, thus preventing rainwater from entering the air supply end 23. This prevents rainwater from entering the connecting cavity 22 through the air supply end 23, and subsequently, during the cooling process, the air carries the rainwater into the outer casing 1, affecting the electrical components inside the casing 1, thereby further improving the operational stability of the recloser.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
