Description

Technical Field

[0001] This invention relates to the field of medium-voltage switchgear technology, and in particular to a primary and secondary integrated solid-sealed pole power supply device. Background Technology

[0002] A solid-sealed pole is a separate component consisting of a vacuum interrupter, or a vacuum interrupter, conductive connections and / or terminals encapsulated in a solid insulating material.

[0003] However, in the secondary power supply process of existing switches, the power supply is met by adding power equipment outside the switch or adding a separate voltage transformer. This requires adding circuits and easily causes the switch to be inspected or repaired and replaced with a new power supply within a certain period of time. As a result, the power taking and disconnecting effect of the solid-sealed pole power taking device is poor and the ease of operation is also reduced. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a primary and secondary fusion solid-sealed pole power extraction device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A primary and secondary fusion solid-sealed pole power extraction device includes a first insulating shell and a second insulating shell. The lower end of the first insulating shell is symmetrically fixedly installed with arc-shaped inserts. The side walls of the two arc-shaped inserts are provided with inner grooves. The inner walls of the two inner grooves are fixedly installed with first springs. The ends of the two first springs away from the inner walls of the inner grooves are fixedly installed with wedge-shaped blocks. The upper end of the second insulating shell is provided with an arc-shaped groove. The inner walls of the arc-shaped grooves are symmetrically provided with limit grooves. The second insulating shell and the first insulating shell are respectively provided with a top cover plate and a moving end cover plate.

[0007] A protective mechanism is fixedly fitted onto the surfaces of both the first and second insulating shells.

[0008] The protective mechanism includes a first fixing ring, and two first fixing rings are respectively fixedly sleeved on the first insulating shell and the second insulating shell. A first annular groove is opened on the opposite ends of the two first fixing rings.

[0009] A power-taking mechanism is fixedly installed on the upper end of the moving end cover plate;

[0010] The power extraction mechanism includes a fixed cover, which is fixedly connected to the moving end cover plate. A wedge-shaped circular groove is provided at the upper end of the fixed cover, and sliding grooves are symmetrically provided inside the fixed cover.

[0011] Preferably, a limiting annular groove is formed in the inner wall of each of the two first annular grooves, and a second limiting ring is slidably installed inside each of the two limiting annular grooves. A telescopic protective cover is fixedly installed on the side wall of each of the two second limiting rings facing away from each other, and the two telescopic protective covers are slidably installed inside the two first annular grooves respectively.

[0012] Preferably, a retaining ring is fixedly installed on the end of each of the two telescopic protective covers away from the second limiting ring, and a second fixing ring is fixedly sleeved on the surface of the first insulating shell and the second insulating shell, with the two first fixing rings located between the two second fixing rings.

[0013] Preferably, each of the two second fixing rings has a slot on its opposite end, and the two retaining rings are respectively adapted to the two slots.

[0014] Preferably, a screw is slidably installed inside the wedge-shaped groove, an internal threaded ring is threaded onto the surface of the screw, and two lifting blocks are fixedly installed at the lower end of the screw.

[0015] Preferably, two sliding bars are symmetrically fixedly installed inside the two lifting blocks, and the two sliding bars are respectively slidably disposed in two sliding grooves. A swing rod is rotatably installed between the two lifting blocks.

[0016] Preferably, clamping blocks are fixedly installed at the lower ends of both swing rods, side blocks are fixedly installed at the opposite ends of both swing rods, and fixing posts are fixedly installed at the opposite ends of both side blocks.

[0017] Preferably, a connecting plate is fixedly installed on each of the two fixed columns at their opposite ends, and a second spring is fixedly installed between the two connecting plates.

[0018] Preferably, a static conductive rod and a moving conductive rod are respectively provided inside the top cover plate and the moving end cover plate, and a fixing plate is fixedly installed at the upper end of the moving conductive rod.

[0019] Preferably, a corrugated tube is sleeved on the surface of the static conductive rod, and the corrugated tube is located inside the second insulating shell.

[0020] Compared with the prior art, the beneficial effects that this invention can achieve are:

[0021] Firstly, the movement of the lifting block causes two fixed sliding bars to slide inside the groove. Simultaneously, the lifting block also causes the swing rod and clamping block connected to it to move. When the clamping block contacts the fixed plate, the two clamping blocks push the fixed plate downwards, causing it to move. The fixed plate then pushes the moving conductive rod to contact the stationary conductive rod, thus completing the power extraction operation. As the clamping block continues to move downwards, it will slightly flip over, clamping the fixed plate. The screw can then be moved upwards, causing the fixed plate to move upwards. This causes the moving conductive rod to move, separating it from the stationary conductive rod and generating an electric arc. The arc is extinguished inside the first and second insulating shells. When the screw moves the swing rod into the wedge-shaped groove, the upper ends of the two swing rods are subjected to a squeezing force, causing the two clamping blocks to release the fixed plate and reset it. This makes the power extraction and disconnection operations of the device quick and convenient.

[0022] Secondly, when the wedge block contacts the second insulating shell, it will be subjected to a squeezing force. Under the squeezing force, the wedge block will slide inside the inner groove. At this time, the wedge block will squeeze the first spring and deform accordingly. After the wedge block is inserted into the inner groove, the arc-shaped insert will also be inserted into the arc-shaped groove. When the wedge block moves into the limiting groove, the first spring will restore its deformation and thus spring the wedge block into the limiting groove to complete the locking. This makes the installation and disassembly of the device more convenient and labor-saving during use.

[0023] Thirdly, as the telescopic protective cover moves, the second limiting ring fixed to it will slide inside the limiting annular groove. When the two second limiting rings slide to the top in the two limiting annular grooves respectively, the telescopic protective cover will deform under the pull of the retaining ring. At this time, the two retaining rings can be engaged in the retaining groove, thereby completing the protection of the first insulating shell and the second insulating shell. This makes the equipment more effective in protecting the first insulating shell and the second insulating shell during use, and extends the service life of the equipment.

[0024] Fourth, during use, the extension length of the screw can be controlled by rotating the internal threaded ring. Since the screw can be clamped to the fixed plate by the swing rod and the clamping block, the position of the moving conductive rod can be effectively adjusted during use, further enhancing the power extraction effect.

[0034] To make the technical means, creative features, and achieved objectives and effects of this invention easier to understand, the invention is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this invention. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0035] like Figures 1 to 8As shown, the primary and secondary fusion solid-sealed pole power extraction device of the present invention includes a first insulating shell 11 and a second insulating shell 12. Arc-shaped inserts 13 are symmetrically fixedly installed at the lower end of the first insulating shell 11. Inner grooves 14 are opened on the side walls of the two arc-shaped inserts 13. First springs 15 are fixedly installed in the inner walls of the two inner grooves 14. Wedge blocks 16 are fixedly installed on the ends of the two first springs 15 away from the inner walls of the inner grooves 14. Arc-shaped grooves 17 are opened at the upper end of the second insulating shell 12. Limiting grooves 18 are symmetrically opened in the inner walls of the arc-shaped grooves 17.

[0036] In use, the two arc-shaped inserts 13 are first inserted into the two arc-shaped grooves 17 respectively. At this time, the arc-shaped inserts 13 will drive the two fixed first springs 15 and wedge blocks 16 to move accordingly. When the wedge blocks 16 contact the second insulating shell 12, the wedge blocks 16 will be subjected to a squeezing force. Under the squeezing force, the wedge blocks 16 will slide inside the inner groove 14. At this time, the wedge blocks 16 will squeeze the first springs 15 and deform accordingly. When the wedge blocks 16 are submerged in the inner groove 14, the arc-shaped inserts 13 will also be submerged in the arc-shaped grooves 17. When block 16 moves into the limiting groove 18, the first spring 15 will restore its deformation and thus spring the wedge block 16 into the limiting groove 18 to complete the engagement, making the installation and disassembly of the device more convenient and labor-saving during use. The second insulating shell 12 and the first insulating shell 11 are respectively provided with a top cover plate 21 and a moving end cover plate 22. The top cover plate 21 and the moving end cover plate 22 are respectively provided with a stationary conductive rod 23 and a moving conductive rod 24. A fixed plate 25 is fixedly installed on the upper end of the moving conductive rod 24. A corrugated tube 26 is sleeved on the surface of the stationary conductive rod 23. The corrugated tube 26 is located inside the second insulating shell 12.

[0037] In some embodiments, the present invention also provides a protective mechanism fixedly fitted on the surfaces of both the first insulating shell 11 and the second insulating shell 12.

[0038] Specifically, the protective mechanism includes a first fixing ring 31, two first fixing rings 31 are respectively fixedly sleeved on the first insulating shell 11 and the second insulating shell 12. A first annular groove 32 is opened on the opposite end of the two first fixing rings 31. A limiting annular groove 33 is opened in the inner wall of the two first annular grooves 32. A second limiting ring 34 is slidably installed inside the two limiting annular grooves 33. A telescopic protective cover 35 is fixedly installed on the opposite side wall of the two second limiting rings 34. The two telescopic protective covers 35 are respectively slidably installed in the two first annular grooves 32. A retaining ring 36 is fixedly installed on the end of the two telescopic protective covers 35 away from the second limiting ring 34. A second fixing ring 37 is fixedly sleeved on the surface of the first insulating shell 11 and the second insulating shell 12. The two first fixing rings 31 are located between the two second fixing rings 37. A retaining groove 38 is opened on the opposite end of the two second fixing rings 37. The two retaining rings 36 are respectively adapted to the two retaining grooves 38.

[0039] After the equipment is installed, the two retaining rings 36 can be pulled relative to each other. The movement of the two retaining rings 36 will cause the two telescopic protective covers 35 fixed thereto to interact inside the first annular groove 32. At this time, the movement of the telescopic protective covers 35 will cause the second limiting rings 34 fixed thereto to slide inside the limiting annular groove 33. When the two second limiting rings 34 slide to the top in the two limiting annular grooves 33, the pull of the retaining rings 36 will cause the telescopic protective covers 35 to deform. At this time, the two retaining rings 36 can be engaged in the retaining groove 38, thereby completing the protection of the first insulating shell 11 and the second insulating shell 12. This makes the protection of the first insulating shell 11 and the second insulating shell 12 better during use and extends the service life of the equipment.

[0040] Meanwhile, the present invention also has a power-taking mechanism fixedly installed on the upper end of the moving end cover plate 22. Specifically, the power-taking mechanism includes a fixed cover 41, which is fixedly connected to the moving end cover plate 22. The upper end of the fixed cover 41 is provided with a wedge-shaped groove 42, and the inside of the fixed cover 41 is symmetrically provided with sliding grooves 43. A screw 44 is slidably installed inside the wedge-shaped groove 42. An internal threaded ring 45 is threaded on the surface of the screw 44. Two lifting blocks 46 are fixedly installed at the lower end of the screw 44. Sliding strips 47 are symmetrically fixedly installed inside the two lifting blocks 46. The two sliding strips 47 are respectively slidably disposed in the two sliding grooves 43. A swing rod 51 is rotatably installed between the two lifting blocks 46. A clamping block 52 is fixedly installed at the lower end of each of the two swing rods 51. A side block 53 is fixedly installed on the opposite end of each of the two swing rods 51. A fixing post 54 is fixedly installed on the opposite end of each of the two side blocks 53. A connecting plate 55 is fixedly installed on the opposite end of each of the two fixing posts 54. A second spring 56 is fixedly installed between the two connecting plates 55.

[0041] In use, first rotate the internal threaded ring 45 on the screw 44 to the top, and then press the screw 44 down. At this time, the movement of the screw 44 will drive the lifting block 46 fixed thereto to move downward inside the fixed cover 41. At this time, the movement of the lifting block 46 will drive the two slide bars 47 fixed thereto to slide inside the slide groove 43 respectively. At the same time, the lifting block 46 will also drive the swing rod 51 and clamping block 52 connected thereto to move. When the clamping block 52 contacts the fixed plate 25, the two clamping blocks 52 will push the fixed plate 25 downward to move. At this time, the fixed plate 25 will push the moving conductive rod 24 to contact the stationary conductive rod 23, thereby completing the power extraction operation.

[0042] As the clamping blocks 52 continue to move downwards, they will slightly flip over, clamping the fixed disk 25. The screw 44 can then be moved upwards, causing the fixed disk 25 to move upwards. This movement of the fixed disk 25 will then cause the moving conductive rod 24 to move, separating it from the stationary conductive rod 23, generating an electric arc. The arc will be extinguished inside the first insulating shell 11 and the second insulating shell 12. When the screw 44 moves the swing rod 51 to the wedge-shaped groove... After the device is inserted into the 42, the upper ends of the two swing rods 51 will be subjected to compressive force. At this time, the two clamping blocks 52 will release the fixed plate 25 and complete the reset. This makes the device quick and convenient to operate when taking on and taking off power. When in use, the extension length of the screw 44 can be controlled by rotating the inner threaded ring 45. Since the screw 44 can clamp the fixed plate 25 through the swing rods 51 and the clamping blocks 52, the position of the moving conductive rod 24 can be effectively adjusted when the device is in use, which further enhances the power taking effect.

[0043] Working principle:

[0044] In the first step, when using the device, insert the two arc-shaped inserts 13 into the two arc-shaped grooves 17 respectively. At this time, the arc-shaped inserts 13 will drive the two fixed first springs 15 and wedge blocks 16 to move. When the wedge blocks 16 come into contact with the second insulating shell 12, the wedge blocks 16 will be subjected to a squeezing force. Under the squeezing force, the wedge blocks 16 will slide inside the inner groove 14. At this time, the wedge blocks 16 will squeeze the first springs 15 and deform accordingly. After the wedge blocks 16 are inserted into the inner groove 14, the arc-shaped inserts 13 will also be inserted into the arc-shaped grooves 17. When the wedge blocks 16 move into the limiting groove 18, the first springs 15 will restore their deformation and thus spring the wedge blocks 16 into the limiting groove 18 to complete the snap-fit. This makes the installation and disassembly of the device more convenient and labor-saving during use.

[0045] The second step involves pulling the two retaining rings 36 relative to each other after the equipment is installed. The movement of the two retaining rings 36 will cause the two telescopic protective covers 35 fixed to them to interact within the first annular groove 32. The movement of the telescopic protective covers 35 will then cause the second limiting rings 34 fixed to them to slide within the limiting annular groove 33. When the two second limiting rings 34 slide to their highest point within the two limiting annular grooves 33, the pull of the retaining rings 36 will cause the telescopic protective covers 35 to deform. At this point, the two retaining rings 36 can be engaged in the retaining groove 38, thus completing the protection of the first insulating shell 11 and the second insulating shell 12. This improves the protection of the first insulating shell 11 and the second insulating shell 12 during use, extending the equipment's service life.

[0046] Thirdly, rotate the internal threaded ring 45 to the top on the screw 44, and then press the screw 44 down. The movement of the screw 44 will cause the lifting block 46, which is fixed to it, to move downwards inside the fixed cover 41. Simultaneously, the movement of the lifting block 46 will cause the two fixed sliding bars 47 to slide within the sliding groove 43. At the same time, the lifting block 46 will also cause the swing rod 51 and clamping block 52, which are rotatably connected to it, to move. When the clamping block 52 contacts the fixed plate 25, the two clamping blocks 52 will push the fixed plate 25 downwards, causing it to move. The fixed plate 25 will then push the moving conductive rod 24 to contact the stationary conductive rod 23, thus completing the power extraction operation. As the clamping block 52 continues to move downwards... At this time, the clamping blocks 52 will slightly flip, and the two clamping blocks 52 will clamp the fixed plate 25. The screw 44 can be moved upward, and the movement of the screw 44 will drive the fixed plate 25 to move upward. At this time, the fixed plate 25 will drive the moving conductive rod 24 to move, so that the moving conductive rod 24 will separate from the stationary conductive rod 23. At this time, an electric arc will be generated, and the first insulating shell 11 and the second insulating shell 12 will extinguish the electric arc. When the screw 44 drives the swing rod 51 to move into the wedge-shaped groove 42, the upper end of the two swing rods 51 will be subjected to the squeezing force. At this time, the two clamping blocks 52 will release the fixed plate 25 and complete the reset, making the power supply and power disconnection of the device quick and convenient during use.

[0047] Fourth step, rotate the internal threaded ring 45. The rotation of the internal threaded ring 45 can control the extension length of the screw 44. Since the screw 44 can clamp the fixed plate 25 through the swing rod 51 and the clamping block 52, the position of the moving conductive rod 24 can be effectively adjusted during use, further enhancing the power extraction effect.

[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
