Description

Technical Field

[0001] The present invention relates to the technical field of air switch circuit breakers, and more specifically, it relates to a high-voltage gas circuit breaker. Background Art

[0002] A high-voltage gas circuit breaker is an electrical device used to disconnect a circuit or isolate a fault in a high-voltage power grid to protect the safe operation of the power system; a high-voltage gas circuit breaker usually needs to be moisture-proof to protect the electrical components and mechanical parts inside the circuit breaker from the influence of a humid environment to ensure the normal operation and long-term reliability of the device.

[0003] A patent application with the publication number CN215417987U discloses an outdoor high-voltage vacuum circuit breaker, belonging to the technical field of circuit breaker devices, including a base. Two fixing plates are fixedly connected to the upper end of the base. A circuit breaker body is arranged on the upper side of the base. Sliders are fixedly connected to the left and right ends of the circuit breaker body. Slide holes are drilled at the right ends of the two fixing plates. The two sliders are respectively slidably connected in the two slide holes. A chute is drilled at the lower end of the circuit breaker body. Two sliding plates are slidably connected in the chute. Threaded holes are drilled at the right ends of the two sliding plates. Lead screws are respectively threadedly connected in the two threaded holes. A turntable is fixedly connected between the two lead screws. A limiting mechanism is arranged on the upper side of the base. Finally, it can be realized that the height of the circuit breaker is conveniently adjusted to prevent the circuit breaker from directly contacting the accumulated water on the ground and causing danger. The operation is simple and the practicability is extremely strong; among them, when it is necessary to move the circuit breaker body upward, it is necessary to hold the turntable by hand and perform a series of operations.

[0004] However, the above technical solution still has deficiencies. Among them, it is necessary to hold the turntable by hand to adjust the upward movement of the circuit breaker body. This process requires manual operation, which is cumbersome. Moreover, in rainy weather, it is very difficult for people to react in time and quickly adjust the upward movement of the circuit breaker body.

[0005] Therefore, the present invention provides a high-voltage gas circuit breaker. Summary of the Invention

[0006] The present invention provides a high-voltage gas circuit breaker to solve the technical problems in the related art that the manual adjustment of the upward movement of the circuit breaker body is relatively cumbersome, and in rainy weather, it is very difficult for people to react in time and adjust the upward movement of the circuit breaker body.

[0007] The present invention provides a high-voltage gas circuit breaker, including: a bottom plate, and further including: a frame disposed above the bottom plate, the front and rear ends of the frame being communicated; a circuit breaker main body installed inside the frame; and a lifting mechanism disposed on the top surface of the bottom plate, the lifting mechanism being capable of automatically lifting the frame and the circuit breaker main body on rainy days; wherein, the lifting mechanism includes: fixing plates disposed on both sides of the frame, a first through hole being opened at the upper end of the fixing plate; a receiving box disposed on the side of the fixing plate away from the frame; and a connecting rope passing through the first through hole and slidably connected to the fixing plate, the two ends of the connecting rope being fixedly connected to the frame and the receiving box respectively.

[0008] Specifically, on rainy days, the sponge body in the receiving box will become heavier and heavier, and the receiving box will drive the frame and the circuit breaker main body to move upward through the connecting rope, which can avoid the contact of the frame and the circuit breaker main body with the wet or waterlogged ground, can automatically perform waterproof and moisture-proof, and avoid the circuit breaker main body from getting damp. The lifting mechanism can automatically lift the frame and the circuit breaker main body, can avoid the contact of the lifting frame and the circuit breaker main body with the wet or waterlogged ground, can automatically perform waterproof and moisture-proof, and avoid the circuit breaker main body from getting damp. There is no need for manual adjustment of the upward movement of the circuit breaker main body, and the circuit breaker main body can be automatically driven to move upward by the weight of rainwater, with timely response, simplicity and convenience.

[0009] Preferably, it further includes a wind shield for protecting and shielding the circuit breaker main body, the wind shield being fixedly connected to the front and rear ends of the fixing plate, and when the lifting mechanism lifts the frame and the circuit breaker main body, the wind shield can cooperate with the frame to shield and protect the circuit breaker main body; and a ventilation mechanism disposed on the bottom plate, the ventilation mechanism being capable of ventilating the circuit breaker main body that has been shielded and protected on rainy days.

[0010] Specifically, the wind shield can cooperate with the frame to shield and protect the circuit breaker main body, and on rainy days, it can avoid the air with high humidity in the wind from blowing on the circuit breaker main body. By setting the ventilation mechanism, the circuit breaker main body can be continuously ventilated. The circuit breaker main body needs to be kept ventilated mainly because harmful gases and fine particles will be released when the circuit breaker main body operates. If the particles are not ventilated and discharged, these particles will adhere to the components of the circuit breaker main body, affecting the service life of the circuit breaker main body. At the same time, ventilation also helps to disperse the heat generated during the operation of the equipment, ensuring the normal operation of the equipment and extending its life.

[0011] Preferably, the ventilation mechanism includes: an air duct passing through the fixing plate, the air outlet end of the air duct being communicated with the inside of the frame and blowing towards the circuit breaker main body; and a blowing component installed at the air inlet end of the air duct, the blowing component being used for blowing air into the air duct, and an air outlet hole being opened at the bottom of the frame.

[0012] Preferably, the lifting mechanism further includes a sponge body disposed inside the receiving box, and a water flow hole being opened at the bottom surface of the receiving box.

[0013] Preferably, the blowing assembly includes: a fan rotatably connected to the air inlet end of the air duct, which can blow air into the air duct when rotating; the air duct on the side of the fixing plate away from the frame is made of a rigid material, and the air duct on the side of the fixing plate close to the frame is made of a soft material; a first annular gear fixedly connected to the outside of the fan; a support rod fixedly connected to the bottom plate; a fixing ring fixedly connected to the top surface of the support rod; a rotating ring rotatably mounted on the fixing ring, which is located below the water flow hole; a plurality of fan blades circumferentially arranged inside the rotating ring, the fan blades being fixedly connected to the rotating ring; and a second annular gear fixedly connected to the rotating ring.

[0014] Specifically, when it rains continuously, the sponge body in the receiving box will become heavier and heavier, and the receiving box will drive the frame and the circuit breaker body to move upward through the connecting rope, which can prevent the frame and the circuit breaker body from contacting the wet or waterlogged ground, can automatically perform waterproof and moisture-proof functions, and prevent the circuit breaker body from being affected by moisture. As it continues to rain, the rainwater in the receiving box flows out through the water flow hole and impacts on multiple fan blades, and the fan blades can rotate. The fan blades drive the fan to rotate through the rotating ring, the second annular gear, and the first annular gear. When the fan rotates, it can blow air into the air duct, which can keep the circuit breaker body ventilated, is beneficial to discharging particulate matters, prevents the particulate matters from adhering to the circuit breaker body, and avoids affecting the service life of the circuit breaker body. At the same time, ventilation also helps to disperse the heat generated during the operation of the equipment, ensures the normal operation of the equipment and extends its life.

[0015] Preferably, it further includes a drying mechanism arranged on the bottom plate, and the drying mechanism is used to dry the air flowing from the ventilation mechanism to the circuit breaker body. The drying mechanism includes: a drying box fixedly connected to the top surface of the fixing plate, and granular desiccants are placed in the drying box, which can be activated carbon desiccants, bentonite desiccants, quartz desiccants, etc.; a collection box fixedly connected to the top surface of the bottom plate; a vertical pipe for connecting the drying box and the collection box, and the vertical pipe intersects and communicates with the air duct; a switch assembly for controlling the flow or closing of the vertical pipe; and two filter meshes arranged in the air duct, and the two filter meshes are arranged on both sides of the vertical pipe.

[0016] Preferably, the switch assembly includes: a switch plate penetrating and slidably connected to the vertical pipe, the switch plate is inclined, and a second through hole is opened on the switch plate; and a pull-down rope for connecting the lower end of the switch plate to the receiving box, and when the receiving box moves downward, it can drive the switch plate to slide downward through the pull-down rope. At the same time, the granular desiccants in the drying box can flow downward through the second through hole; a reset member arranged on the upper end of the switch plate for driving the switch plate to move.

[0017] Preferably, the reset member includes: a fixing platform fixedly connected to the upper end of the switch plate; and a reset spring arranged between the fixing platform and the vertical pipe.

[0018] Preferably, a sliding groove is formed on the top surface of the accommodation box. The switch assembly further includes a moving block slidably disposed in the sliding groove, and the lower end of the downward pull rope is fixedly connected to the moving block.

[0019] Preferably, the second through hole is triangular in shape. When the switch plate moves downward by a greater distance, the flow rate of the granular desiccant through the second through hole is faster.

[0020] Specifically, when it rains, the humidity in the air is relatively high. The humid air may cause the main body of the circuit breaker to be affected by moisture, resulting in a decrease in insulation performance and even problems such as circuit short - circuit. By providing a drying mechanism, when it rains more heavily, the sponge body in the accommodation box absorbs more water, and the accommodation box moves downward at a faster speed and for a longer distance. The impact force of the rain flowing out from the water flow holes and hitting the multiple fan blades is also greater, so the rotation speed of the fan is faster, and the wind speed of the air duct blowing on the main body of the circuit breaker is faster. At this time, it means that more air volume needs to be dried in the air duct. When it rains more heavily, the accommodation box drives the switch plate to move downward by a longer distance through the downward pull rope, and the distance that the switch plate can be driven to move downward is greater. When the switch plate moves downward by a greater distance, the flow rate of the granular desiccant through the second through hole is faster. The faster the flow rate and the more the flow volume of the granular desiccant can automatically meet the drying of more air volume in the air duct. When more air volume is blown into the main body of the circuit breaker in the air duct, it ensures that the drying mechanism can meet the drying of more air volume.

[0021] The beneficial effects of the present invention are as follows: For a high - voltage gas circuit breaker described in the present invention, specifically, when it rains, the sponge body in the accommodation box becomes heavier and heavier, and the accommodation box drives the frame and the main body of the circuit breaker to move upward through the connecting rope, which can avoid the frame and the main body of the circuit breaker from contacting the wet or water - logged ground, can automatically perform waterproof and moisture - proof functions, and avoid the main body of the circuit breaker from being affected by moisture. The lifting mechanism can automatically lift the frame and the main body of the circuit breaker, can avoid the frame and the main body of the circuit breaker from contacting the wet or water - logged ground, can automatically perform waterproof and moisture - proof functions, and avoid the main body of the circuit breaker from being affected by moisture. There is no need for manual adjustment of the upward movement of the main body of the circuit breaker, and the main body of the circuit breaker can be automatically driven to move upward by the weight of the rain, with timely response, simplicity and convenience.

[0022] A high-voltage gas circuit breaker according to the present invention, the wind deflector can cooperate with the frame to shield and protect the circuit breaker body. When it rains, it can prevent the air with high humidity in the wind from blowing on the circuit breaker body. By setting a ventilation mechanism, continuous ventilation can be carried out on the circuit breaker body. The circuit breaker body needs to maintain ventilation mainly because harmful gases and fine particles will be released when the circuit breaker body operates. If the particles are not ventilated and discharged, these particles will adhere to the components of the circuit breaker body, affecting the service life of the circuit breaker body. At the same time, ventilation also helps to dissipate the heat generated during the operation of the equipment, ensuring the normal operation of the equipment and extending its life.

[0023] A high-voltage gas circuit breaker according to the present invention, when it rains continuously, the sponge body in the receiving box will become heavier and heavier, and the receiving box will drive the frame and the circuit breaker body to move upward through the connecting rope, which can prevent the frame and the circuit breaker body from contacting the wet or waterlogged ground, and can automatically carry out waterproof and moisture-proof to avoid the circuit breaker body from being affected by moisture. As it continues to rain, the rainwater in the receiving box flows out through the water flow holes and impacts on multiple fan blades. The fan blades can rotate, and the fan blades drive the fan to rotate through the rotating ring, the second ring gear, and the first ring gear. When the fan rotates, it can blow air into the air duct, which can keep ventilating the circuit breaker body, is conducive to discharging particles, preventing the particles from adhering to the circuit breaker body, and avoiding affecting the service life of the circuit breaker body. At the same time, ventilation also helps to dissipate the heat generated during the operation of the equipment, ensuring the normal operation of the equipment and extending its life.

[0024] A high-voltage gas circuit breaker according to the present invention, when it rains harder, the receiving box will drive the switch board to move downward by a longer distance through the pull-down rope, and can drive the switch board to move downward by a greater distance. When the switch board moves downward by a greater distance, the granular desiccant flows through the second through hole at a faster speed. The faster the flow rate and the more the flow volume of the granular desiccant can automatically meet the drying of more air volume in the air duct. When more air volume is blown into the circuit breaker body in the air duct, it is ensured that the drying mechanism can meet the drying of more air volume. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] Embodiment

[0034] As Figures 1 to 6 shown, a high-voltage gas circuit breaker according to an embodiment of the present invention is hereinafter referred to with emphasis to Figure 1 , Figure 2 , and includes: a bottom plate 1, and further includes: a frame 2 disposed above the bottom plate 1, with the front and rear ends of the frame 2 being interconnected; a circuit breaker main body 3 installed inside the frame 2; and a lifting mechanism 4 disposed on the top surface of the bottom plate 1, where the lifting mechanism 4 can automatically lift the frame 2 and the circuit breaker main body 3 on rainy days; wherein, the lifting mechanism 4 includes: fixed plates 41 disposed on both sides of the frame 2, with first through holes 42 opened at the upper ends of the fixed plates 41; an accommodating box 43 disposed on the side of the fixed plate 41 away from the frame 2; and a connecting rope 44 passing through the first through holes 42 and slidably connected to the fixed plates 41, with both ends of the connecting rope 44 fixedly connected to the frame 2 and the accommodating box 43 respectively.

[0035] Specifically, on rainy days, the sponge body 45 in the storage box 43 will become heavier and heavier. The storage box 43 will drive the frame 2 and the circuit breaker body 3 to move upward through the connecting rope 44, which can prevent the frame 2 and the circuit breaker body 3 from contacting the wet or waterlogged ground, can automatically carry out waterproofing and moisture-proofing, and prevent the circuit breaker body 3 from being affected by moisture. The lifting mechanism 4 can automatically lift the frame 2 and the circuit breaker body 3, can prevent the frame 2 and the circuit breaker body 3 from contacting the wet or waterlogged ground, can automatically carry out waterproofing and moisture-proofing, and prevent the circuit breaker body 3 from being affected by moisture. There is no need for manual adjustment of the upward movement of the circuit breaker body 3, and the circuit breaker body 3 can be automatically driven to move upward by the weight of the rain, with timely response, simplicity and convenience.

[0036] Please refer specifically to Figure 1 、 Figure 2 It also includes a wind shield 5 for protecting and shielding the circuit breaker body 3. The wind shield 5 is fixedly connected to the front and rear ends of the fixed plate 41. When the lifting mechanism 4 lifts the frame 2 and the circuit breaker body 3, the wind shield 5 can cooperate with the frame 2 to shield and protect the circuit breaker body 3; and a ventilation mechanism 6 provided on the bottom plate 1. The ventilation mechanism 6 can ventilate the circuit breaker body 3 that has been shielded and protected on rainy days.

[0037] Specifically, the wind shield 5 can cooperate with the frame 2 to shield and protect the circuit breaker body 3. When it rains, it can prevent the air with high humidity in the wind from blowing on the circuit breaker body 3. By setting the ventilation mechanism 6, the circuit breaker body 3 can be continuously ventilated. The circuit breaker body 3 needs to maintain ventilation mainly because the circuit breaker body 3 will release harmful gases and fine particles during operation. If the particles are not ventilated and discharged, these particles will adhere to the components of the circuit breaker body 3, affecting the service life of the circuit breaker body 3. At the same time, ventilation also helps to disperse the heat generated during the operation of the equipment, ensuring the normal operation of the equipment and extending its life.

[0038] Please refer specifically to Figure 2 The ventilation mechanism 6 includes: an air duct 61 penetrating through the fixed plate 41. The air outlet end of the air duct 61 communicates with the inside of the frame 2 and blows towards the circuit breaker body 3; and a blowing component 62 installed at the air inlet end of the air duct 61. The blowing component 62 is used to blow air into the air duct 61. An air outlet hole 63 is opened at the bottom of the frame 2.

[0039] Please refer specifically to Figure 1 、 Figure 2 The lifting mechanism 4 also includes a sponge body 45 arranged inside the storage box 43. A water flow hole 46 is opened at the bottom surface of the storage box 43.

[0040] Please refer specifically to Figure 2 、 Figure 3, the blowing component 62 includes: a fan 621 rotatably connected to the air inlet end of the air duct 61, which can blow air into the air duct 61 when rotating; the air duct 61 is made of a hard material on the side away from the frame 2 of the fixing plate 41, and the air duct 61 is made of a soft material on the side close to the frame 2 of the fixing plate 41; a first annular gear 622 fixedly connected to the outside of the fan 621; a support rod 623 fixedly connected to the bottom plate 1; a fixing ring 624 fixedly connected to the top surface of the support rod 623; a rotating ring 625 rotatably mounted on the fixing ring 624, and the rotating ring 625 is located below the water flow hole 46; a plurality of fan blades 626 circumferentially arranged inside the rotating ring 625, and the fan blades 626 are fixedly connected to the rotating ring 625; and a second annular gear 627 fixedly connected to the rotating ring 625.

[0041] Specifically, when it rains continuously, the sponge body 45 in the receiving box 43 will become heavier and heavier, and the receiving box 43 will drive the frame 2 and the circuit breaker body 3 to move upward through the connecting rope 44, which can prevent the frame 2 and the circuit breaker body 3 from contacting the wet or waterlogged ground, and can automatically carry out waterproof and moisture-proof functions to prevent the circuit breaker body 3 from being affected by moisture. As it continues to rain, the rainwater in the receiving box 43 flows out from the water flow hole 46 and impacts on the multiple fan blades 626. The fan blades 626 can rotate, and the fan blades 626 drive the fan 621 to rotate through the rotating ring 625, the second annular gear 627, and the first annular gear 622. When the fan 621 rotates, it can blow air into the air duct 61, which can keep the circuit breaker body 3 ventilated, is beneficial to discharging particulate matters, prevents the particulate matters from adhering to the circuit breaker body 3, and avoids affecting the service life of the circuit breaker body 3. At the same time, ventilation also helps to dissipate the heat generated during the operation of the equipment, ensuring the normal operation of the equipment and extending its life.

[0042] Please refer specifically to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , and further includes a drying mechanism 7 arranged on the bottom plate 1. The drying mechanism 7 is used to dry the air flowing from the ventilation mechanism 6 to the circuit breaker body 3. The drying mechanism 7 includes: a drying box 71 fixedly connected to the top surface of the fixing plate 41, and granular desiccants are placed in the drying box 71, and activated carbon desiccants, bentonite desiccants, quartz desiccants, etc. can be used; a collection box 72 fixedly connected to the top surface of the bottom plate 1; a vertical pipe 73 for connecting the drying box 71 and the collection box 72, and the vertical pipe 73 intersects and communicates with the air duct 61; a switch component 74 for controlling the flow or closing of the vertical pipe 73; and two filter meshes 75 arranged in the air duct 61, and the two filter meshes 75 are arranged on both sides of the vertical pipe 73.

[0043] Please refer specifically to Figure 5 , Figure 6, the switch assembly 74 includes: a switch plate 741 that penetrates and is slidably connected to the vertical pipe 73. The switch plate 741 is inclined, and a second through hole 742 is formed in the switch plate 741; and a pull-down rope 743 for connecting the lower end of the switch plate 741 to the receiving box 43. When the receiving box 43 moves downward, it can drive the switch plate 741 to slide downward through the pull-down rope 743. At the same time, the granular desiccant in the drying box 71 can flow downward through the second through hole 742; a reset member 744 provided at the upper end of the switch plate 741 for driving the switch plate 741 to move.

[0044] Please refer specifically to Figure 5 , the reset member 744 includes: a fixed platform 7441 fixedly connected to the upper end of the switch plate 741; and a reset spring 7442 provided between the fixed platform 7441 and the vertical pipe 73.

[0045] Please refer specifically to Figure 4 、 Figure 5 , a sliding groove 745 is formed on the top surface of the receiving box 43. The switch assembly 74 further includes a moving block 746 slidably disposed in the sliding groove 745, and the moving block 746 is fixedly connected to the lower end of the pull-down rope 743.

[0046] Please refer specifically to Figure 6 , the second through hole 742 is triangular in shape. When the switch plate 741 moves downward by a greater distance, the flow rate of the granular desiccant through the second through hole 742 is faster.

[0047] Specifically, since during rain, the humidity in the air is relatively high, the humid air may cause the main body of the circuit breaker 3 to be affected by moisture, resulting in a decline in insulation performance, and even causing problems such as a short circuit in the circuit. By setting up the drying mechanism 7, when it rains more heavily, the sponge body 45 in the receiving box 43 absorbs more water, and the receiving box 43 will move downward at a faster speed and for a longer distance. The impact force of the rain flowing out from the water flow hole 46 and hitting the multiple fan blades 626 will also be greater, and the rotational speed of the fan 621 will be faster. The wind speed of the air duct 61 blowing air on the main body of the circuit breaker 3 will be faster. At this time, it means that the amount of air that needs to be dried in the air duct 61 is more. When it rains more heavily, the receiving box 43 will drive the switch plate 741 to move downward by a longer distance through the pull-down rope 743, and the distance that can drive the switch plate 741 to move downward is greater. When the switch plate 741 moves downward by a greater distance, the flow rate of the granular desiccant through the second through hole 742 is faster. The faster the flow rate and the more the flow volume of the granular desiccant can automatically meet the drying of more air volume in the air duct 61. When more air volume is blown into the main body of the circuit breaker 3 in the air duct 61, it ensures that the drying mechanism 7 can meet the drying of more air volume.

[0048] The above has described the embodiments of this embodiment, but this embodiment is not limited to the above specific implementation manners. The above specific implementation manners are merely illustrative rather than restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
