Description

Technical Field

[0001] The invention belongs to the technical field of vacuum circuit breakers, and in particular relates to an energy-saving high-voltage vacuum circuit breaker. Background Art

[0002] The vacuum circuit breaker is named because its arc extinguishing medium and the insulating medium of the contact gap after arc extinguishing are both high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and no need for maintenance after arc extinguishing, and is widely used in distribution networks.

[0003] The working principle of the energy-saving high-voltage vacuum circuit breaker mainly includes four steps: disconnection, arc extinguishing, separation and recovery. When the circuit needs to be cut off, the main contacts of the circuit breaker will quickly separate to generate an arc. Then, the circuit breaker uses the insulation properties of the vacuum to quickly generate an arc extinguishing electric field to compress and extinguish the arc. After the arc is extinguished, the main contacts and fixed contacts of the circuit breaker will completely separate and return to normal working condition.

[0004] However, the conventional device still has the following problems when used:

[0005] The patent application publication number CN218497993U discloses an energy-saving outdoor high-voltage vacuum circuit breaker. When the outdoor temperature is low, the structure inside the base can ensure that it can operate at a normal temperature, greatly reducing energy consumption under low outdoor temperature conditions and being more energy-efficient.

[0006] During the opening and closing process of the circuit breaker, high-voltage arcs or live parts are generated. Direct contact by operators can easily cause electric shock accidents, posing a serious threat to personal safety. Especially in harsh environments such as humidity, high temperature, and high voltage, manual operation of circuit breakers may be more difficult and dangerous.

DETAILED DESCRIPTION

[0034] In order to make the purpose and technical solution of the present invention clearly and completely described, and the advantages more clearly understood, the embodiments of the present invention are further described in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, not all of them, and are only used to explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] For example, see Figures 1 to 12 The present invention provides a technical solution: it includes a base 1 and a protective shell 2, the protective shell 2 is slidably connected with a placement plate 21 inside, the outer wall at the top of the placement plate 21 is in active contact with the outer wall at the bottom of the base 1, the two sides inside the protective shell 2 are fixedly connected with limiting rods 22, the outer walls at the bottom of the two limiting rods 22 are in active contact with the outer wall at the top of the placement plate 21, the outer wall on one side of the protective shell 2 is fixedly connected with a device shell 3, the outer wall on one side of the base 1 is rotatably connected with a control member 11, the inside of the device shell 3 is fixedly connected with a control mechanism, the outer walls opposite to the two limiting shells 44 are fixedly connected with a connecting rod 43, the outer wall at one end of the connecting rod 43 is fixedly connected with a handle 1 431, the outer wall at the bottom of the handle 1 431 is fixedly connected with a limiting groove 432, the outer wall on one side of the limiting groove 432 is fixedly connected with a protrusion, the inner thread of the protrusion is connected with a threaded rod 2 433, and the outer wall at one end of the threaded rod 2 433 is rotatably connected with the outer wall on one side of the device shell 3.

[0036] By the operator manually rotating the threaded rod 433, the movement of the threaded rod 433 can cause the protrusion to drive the limiting groove 432 to move accordingly. When the limiting groove 432 moves forward on the threaded rod 433, the limiting groove 432 can leave the outside of the handle 8, thereby releasing the fixation of the handle 8. At this time, the handle 8 can be moved at will, avoiding the movement of the handle 8 under the influence of external force when it is not needed to work, thereby correspondingly increasing the stability of the handle 8 and improving the safety of the overall structure.

[0037] It should be noted that the control component 11 is a control component 11 for controlling the power on and off of the energy-saving high-voltage vacuum circuit breaker in the prior art. The control component 11 is a key component in the circuit breaker for controlling the on and off of the main circuit. When the circuit needs to be connected, the control component 11 will close the main contacts of the circuit breaker, thereby allowing current to flow. Conversely, when the circuit needs to be disconnected, it will operate the main contacts to open, thereby quickly cutting off the current.

[0038] Embodiment 2, on the basis of embodiment 1, an elastic plate 23 is fixedly connected to the lower part of the interior of the protective shell 2, a plurality of elastic plates 23 are fixedly connected to the inner part of a supporting elastic ball 24, the outer wall at the top of the elastic plate 23 is fixedly connected to the outer wall at the bottom of the placement plate 21, a plurality of shells 4 are fixedly connected to the lower part of the interior of the protective shell 2, a support rod 42 is slidably connected to the inner part of the shell 4, a support spring 45 is fixedly connected to the outer wall at the bottom of the support rod 42, a groove 1 is provided on the outer wall on one side of the support rod 42, a groove 2 is provided on the outer wall on one side of the shell 4, a fixing rod 46 is slidably connected to the inner part of the fixing rod 46, and the inner part of the fixing rod 46 is fixedly connected to the outer wall on the bottom of the supporting rod 42. The wall is fixedly connected with a push spring 47, the outer wall of one end of the push spring 47 is fixedly connected to the outer wall of one side of the shell body 4, the outer wall of the fixing rod 46 is movably inserted into the inside of the groove one, the interior of the protective shell 2 is fixedly connected with a mounting groove 41 at a position between the two shell bodies 4, through holes are provided on both sides of the mounting groove 41 at the position of the fixing rod 46, the interior of the mounting groove 41 is slidably connected with a limit shell 44, the interior of the limit shell 44 is fixedly connected with a spring piece 441, the outer wall on one side of the spring piece 441 is fixedly connected with a push block 442, and the outer wall on one side of the push block 442 is movably contacted with the outer wall on one side of the fixing rod 46.

[0039] By pushing the fixing rod 46 toward the outside of the support rod 42 under the action of the push spring 47, the fixing rod 46 slides out from the inside of the groove 1, thereby releasing the fixing of the fixing rod 46 to the support rod 42, allowing the support rod 42 to move inside the shell 4, so that the buffer mechanism starts to work. The work of the buffer mechanism helps to reduce mechanical vibration and impact during the opening and closing process, thereby improving the accuracy and stability of the opening and closing action, helping to ensure that the circuit breaker can accurately cut off or close the circuit during the opening and closing process, and preventing power grid accidents caused by improper operation or mechanical failure.

[0040] Embodiment three, on the basis of embodiment two, the limiting springs 6 are fixedly connected to the two sides inside the mounting seat 7, the outer wall of one end of the limiting spring 6 is fixedly connected to the limiting tooth 61, the outer wall on one side of the limiting tooth 61 is movably plugged into the outer wall of the driving wheel 52, the outer wall on one side of the limiting tooth 61 is fixedly connected to the push rod 62, the outer wall of the push rod 62 is slidably connected to the inside of the slide groove four 73, the outer wall of the bottom of the moving block 84 is fixedly connected to the push block two 63, the outer wall of the push block two 63 is slidably connected to the inside of the slide groove three 72, and the outer wall of the push block two 63 is movably contacted with the outer wall of one end of the push rod 62.

[0041] By moving the moving block 84, the pushing block 2 63 can be driven to move inside the sliding groove 3 72. When the pushing block 2 63 moves to contact the push rod 62 and continues to move, the pushing rod 62 drives the limiting tooth 61 to move inside the sliding groove 4 73, so that one side of the limiting tooth 61 leaves the outer wall of the driving wheel 52, and the limiting of the driving wheel 52 can be released. Through the cooperation of the pushing block 2 63 and the push rod 62, the limiting of the driving wheel 52 can be quickly and accurately released, thereby shortening the operation time of the driving wheel 52 and improving the work efficiency of the operator.

[0042] Embodiment 4, on the basis of embodiment 3, the control mechanism includes a clamping rod 5 and a threaded rod 51, the outer walls of the upper and lower ends of the two threaded rods 51 are rotatably connected to the inside of the device shell 3, the outer walls of one end of the two clamping rods 5 are fixedly connected to the outer walls at both ends of the control member 11, the clamping rod 5 is in an L-shape, the other end of the clamping rod 5 is provided with a threaded hole connected to the outer walls on both sides, the inside of the threaded hole is threadedly connected to the outer wall of the threaded rod 51, a driving wheel 52 is fixedly connected to the lower part of the outer wall of the threaded rod 51, a mounting seat 7 is fixedly connected to the lower part of the inside of the device shell 3, a second slide groove 71 is provided in the middle of the outer wall of one side of the mounting seat 7, a third slide groove 72 is provided at the lower part of the inside of the second slide groove 71, a fourth slide groove 73 is provided at the lower part of the outer wall of the mounting seat 7 near the two sides of the second slide groove 71, the opposite side of the two fourth slide grooves 73 is connected with the outer walls at both ends of the third slide groove 72, and the slide grooves The inner wall of the second 71 is fixedly connected with a magnetic plate, and the inner sliding connection of the second slide groove 71 is a moving block 84, and the outer wall on one side of the moving block 84 is fixedly connected with a magnetic block, and the outer wall on one side of the magnetic block and the outer wall on one side of the magnetic plate attract each other with opposite poles, and the outer wall on the other end of the moving block 84 is fixedly connected with a mounting plate, and the middle position of one side of the mounting plate is rotatably connected with a main rod 81, and the outer wall of the main rod 81 is fixedly connected with a main gear 83, and the outer wall of one side of the mounting plate is located on both sides of the main rod 81 and is rotatably connected with a rotating shaft, and the outer walls of the two rotating shafts are fixedly connected with a driven wheel 82, and the outer wall of the driven wheel 82 is meshed with the outer wall of the driving wheel 52, and the outer wall of the main gear 83 is meshed with the outer wall of the driven wheel 82, and the outer wall of one end of the main rod 81 is fixedly connected with a handle 2 8, and the outer wall of the handle 2 8 is movably plugged into the bottom of the limiting groove 432, and the outer wall of the main rod 81 is slidably connected to the inside of the slide groove 31.

[0043] The operator only needs to turn the handle 2 8 to complete the driving and control of a series of mechanical components, which greatly simplifies the operation process, makes the operation more intuitive and convenient, and reduces the difficulty and complexity of the operation. The movement of the control part 11 is achieved through mechanical linkage, which avoids the operator from directly contacting the control part 11. Correspondingly, through the remote operation of the handle 2 8, the operator can complete the operation in a safer and more comfortable environment, reducing the difficulty and complexity of the operation.

[0044] The working principle and use process of the present invention are as follows: first, the operator rotates the threaded rod 433 by hand, and then the movement of the threaded rod 433 can drive the limit groove 432 to move accordingly. When the limit groove 432 moves forward on the threaded rod 433, the limit groove 432 can leave the outside of the handle 8, thereby releasing the fixation of the handle 8. At this time, the handle 8 can be moved at will, avoiding the movement of the handle 8 under the influence of external force when it is not needed to work, thereby correspondingly increasing the stability of the handle 8 and improving the safety of the overall structure.

[0045] By utilizing the movement of the limiting groove 432, the handle 431 can drive the connecting rod 43 to move toward the outside of the installation groove 41, and then the movement of the connecting rod 43 can drive the limiting shell 44 to move inside the installation groove 41. When the limiting shell 44 leaves the position of the through hole, it will drive the pushing block 442 to enter the inside of the installation groove 41. At this time, the pushing block 442 is squeezed by the outer shell of the installation groove 41 and moves toward the inside of the limiting shell 44. Then, by utilizing the movement of the pushing block 442, the spring piece 441 is squeezed into the inside of the limiting shell 44. At this time, the pushing block 442 and the fixing rod 442 are One side of 46 is separated, and then the fixing rod 46 is pushed to move to the outside of the support rod 42 under the action of the pushing spring 47, so that the fixing rod 46 slides out from the inside of the groove 1, thereby releasing the fixing of the fixing rod 46 to the support rod 42, and the support rod 42 moves inside the shell 4, so that the buffer mechanism starts to work. The work of the buffer mechanism helps to reduce the mechanical vibration and impact during the opening and closing process, thereby improving the accuracy and stability of the opening and closing action, helping to ensure that the circuit breaker can accurately cut off or close the circuit during the opening and closing process, and preventing power grid accidents caused by improper operation or mechanical failure.

[0046] It should be noted that the elastic force of the spring 441 itself is greater than the elastic force of the push spring 47 itself.

[0047] By releasing the fixation of handle 2 8, the operator can hold handle 2 8 and move it to the right or left. When handle 2 8 drives main rod 81 to move inside slide groove 1 31, the movement of main rod 81 under force can make the mounting plate drive moving block 84 to slide to the left inside slide groove 2 71 on mounting seat 7, and then the movement of moving block 84 can drive pushing block 2 63 to move inside slide groove 3 72. When pushing block 2 63 moves to contact with push rod 62 and continues to move, pushing push rod 62 drives limiting tooth 61 to move inside slide groove 4 73, so that one side of limiting tooth 61 leaves the outer wall of driving wheel 52, and the limit of driving wheel 52 can be released. Through the cooperation of pushing block 2 63 and push rod 62, the limit of driving wheel 52 can be quickly and accurately released, thereby shortening the operation time of driving wheel 52, thereby improving the working efficiency of the operator.

[0048] When the main rod 81 moves to the leftmost side of the slide groove 1 31, the movement of the slide groove 1 31 can be stopped, and then the magnetic plate arranged inside the slide groove 2 71 can be used to connect the magnetic block to the magnetic plate after the moving block 84 drives the magnetic block to move to any position inside the slide groove 2 71 and stops. By setting the magnetic block and the magnetic plate, the stability of the moving block 84 can be increased when the moving block 84 stops moving, thereby avoiding the moving block 84 from shaking left and right when the main rod 81 is rotated, thereby correspondingly improving the fixing effect of the moving block 84.

[0049] When the main rod 81 moves to the leftmost side of the slide groove 1 31, the driven wheel 82 can be meshed with the driving wheel 52 while the fixing of the driving wheel 52 is released. At this time, the operator can turn the handle 2 8 to drive the main rod 81 to rotate. The rotation of the main rod 81 can drive the driven wheel 82 to move, so that the driven wheel 82 drives the driving wheel 52 to move. The movement of the driving wheel 52 can make the threaded rod 1 51 drive the clamping rod 5 to move, so that the clamping rod 5 drives the control member 11 to move. The operator only needs to turn the handle 2 8 to complete the driving and control of a series of mechanical parts, which greatly simplifies the operation process, makes the operation more intuitive and convenient, and reduces the difficulty and complexity of operation. The movement of the control member 11 is realized by mechanical linkage, which avoids the operator from directly contacting the control member 11. Correspondingly, the remote operation of the handle 2 8 allows the operator to complete the operation in a safer and more comfortable environment, reducing the difficulty and complexity of operation.

[0050] During the opening and closing operations of the high-voltage vacuum circuit breaker, the circuit breaker will generate certain mechanical vibrations. At this time, the vibration force on the base 1 is transmitted to the support rod 42 and the elastic plate 23 through the placement plate 21. The movement generated by the elastic plate 23 and the support rod 42 under force can reduce the vibration force on the base 1. Then, by setting the supporting elastic ball 24, the elastic plate 23 can be pushed to quickly return to its original position after the elastic plate 23 eliminates the vibration force. At this time, the support rod 42 is pushed back to its original position under the action of the supporting spring 45. Due to the characteristics of the material of the elastic plate 23, part of the vibration energy can be absorbed and dispersed, thereby reducing the impact force on the base 1. Although the supporting spring 45 at the bottom of the support rod 42 also bears part of the vibration force, its main function is to work in coordination with the elastic plate 23 to jointly bear and disperse the vibration energy. The setting of the supporting elastic ball 24 plays a key role after the elastic plate 23 eliminates the vibration force. It can provide reverse thrust after the elastic plate 23 is deformed, helping the elastic plate 23 to quickly return to its original position. This rapid recovery ability helps to reduce the continuous impact of vibration on the base 1 and improve the stability of the base 1.

[0051] When the handle 2 8 moves to the bottom of the limit groove 432 again, by rotating the threaded rod 2 433, the protrusion drives the limit groove 432 to move back on the threaded rod 2 433, so that the limit groove 432 fixes the handle 2 8 again, and the limit shell 44 moves to the position of the through hole. Under the action of the spring 441, the pushing block 1 442 is pushed to squeeze the fixing rod 46, so that the fixing rod 46 enters the inside of one side of the groove again, fixes the support rod 42 again, and stops the buffer mechanism from working. After the opening and closing work is completed, the buffer mechanism continues to work, which will waste energy. Therefore, fixing it and stopping it from working can reduce unnecessary energy consumption and improve energy utilization efficiency.

[0052] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
