Description

Technical Field

[0001] This application belongs to the technical field of power equipment and relates to an outdoor high-voltage disconnector mechanism and device. Background Art

[0002] In the power system, an outdoor high-voltage disconnector is one of the indispensable important devices in the power line, and its function is to ensure that the power line can safely cut off or close the current during maintenance, inspection or failure.

[0003] As a common type of disconnector, the GW9 outdoor high-voltage disconnector includes a base, a post insulator and a switch mechanism. The switch mechanism includes two moving contacts, two static contacts, and a plurality of bolts and springs. One end of the moving contact is hinged to one of the static contacts, and the other end of the moving contact can rotate to the other static contact; the bolt passes through the two moving contacts, and a washer and a nut are provided at one end of the bolt. The washer and the bolt head respectively abut against the outer walls of the two moving contacts, and the two ends of the spring respectively abut against the washer and the nut. The elastic force of the spring is used to force the washer to move close to the bolt head direction, so that the two moving contacts approach each other, so that the inner sides of the moving contacts can be closely attached to the outer sides of the two static contacts to achieve stable conduction.

[0004] In order to improve the stability of the closing of the two moving contacts, the bolts and springs are provided in multiple numbers and arranged at intervals along the length direction of the moving contact, so as to ensure that each part of the moving contact in the length direction is subjected to elastic force, so as to improve the position stability of the moving contact and the clamping and fitting stability of the moving contact to the static contact. However, when tightening the moving contact, it is necessary to sequentially tighten multiple nuts to increase the pre-tightening force of the spring, and the operation is relatively cumbersome. Summary of the Invention

[0005] In order to improve the convenience of tightening the moving contact, an outdoor high-voltage disconnector mechanism and device are provided.

[0006] This application provides an outdoor high-voltage disconnector mechanism, and specifically adopts the following technical solutions to achieve:

[0007] An outdoor high-voltage disconnector mechanism includes two moving contact pieces, a first static contact piece, a second static contact piece, and an elastic closing assembly. The elastic closing assembly includes a first spring, a locking structure, two groups of pin shafts, two rotating cylinders, and two traction lines. The two groups of pin shafts are respectively located at both ends of the moving contact piece in the length direction. The two rotating cylinders are located in the middle of the moving contact piece in the length direction and are coaxially arranged. One group of pin shafts includes three pin shafts arranged at intervals in the length direction of the moving contact piece. The pin shaft farthest from the rotating cylinder in one group of pin shafts is named the first pin shaft, and the other pin shafts are named the second pin shafts. The moving contact piece is provided with mounting holes for the pin shafts to slide through. One end of the pin shaft is fixed with a limiting block, and the other end of the pin shaft is slidably sleeved with a first sliding ring and a second sliding ring. The first sliding ring and the limiting block respectively abut against the opposite surfaces of the two moving contact pieces. The two ends of the first spring respectively abut against the opposite end faces of the first sliding ring and the second sliding ring. The first springs of adjacent two pin shafts are respectively located on both sides of the moving contact piece. The second sliding ring is provided with a supporting rod. One end of the traction line is fixedly connected to the supporting rod of the second sliding ring of the first pin shaft. The other end of the traction line sequentially bypasses the supporting rods of the second sliding rings of each second pin shaft and is fixedly wound around the rotating cylinder. The locking structure is used to transmit torque to the rotating cylinder, and the rotation directions of the two rotating cylinders are opposite, and the locking structure is also used to relatively fix the two rotating cylinders.

[0008] Through the above technical solution, during installation, first ensure that the two moving contact pieces are in a separated state. At this time, the first spring is not compressed or the compression degree is small to ensure that there is enough clearance between the two moving contact pieces. Then turn the moving contact pieces so that the two moving contact pieces are respectively located on both sides of the first static contact piece and the second static contact piece. Then apply two torques in opposite directions to the locking structure. The locking structure transmits the torques in different directions to the rotating cylinders respectively. The rotating cylinders rotate to tighten the traction lines. The traction lines are tightened to drive the supporting rods and the second sliding rings to axially slide in the direction towards the first sliding ring. The first springs on each pin shaft are compressed. The elastic force of the first spring is applied to the moving contact piece through the first sliding ring to force the two moving contact pieces to move towards each other and tighten, so that the moving contact pieces are respectively in close contact with the first static contact piece and the second static contact piece to complete the circuit conduction. Finally, the locking structure relatively fixes the two rotating cylinders. And because the winding directions of the two rotating cylinders for the traction lines are opposite, the reaction pulling forces of the first springs of the two groups of pin shafts for the traction lines are opposite, that is, the reaction pulling forces of the two rotating cylinders for the traction lines are opposite, and the reaction pulling forces of the two rotating cylinders cancel each other out, thereby ensuring the stability of the state of the traction lines and further ensuring the stability of the position states of the two moving contact pieces.

[0009] In summary, by setting the traction line, the support rod, the rotating cylinder and the locking structure, the torque in different directions is respectively transmitted to the rotating cylinder by using the locking structure, and the rotating cylinder rotates to tighten the traction line, so as to compress each first spring at the same time, so that the two moving contact pieces move towards each other and are stably tightened, so that the moving contact pieces are closely and stably attached to the first static contact piece and the second static contact piece respectively, which is more convenient and has strong installation stability; secondly, by using the characteristic that the reaction pulling forces of the traction lines received by the two rotating cylinders are in opposite directions to form an interlock, thereby ensuring the stability of the position states of the two moving contact pieces.

[0010] Optionally, both ends of the moving contact piece are convexly provided with a first protrusion and a second protrusion, wherein the first protrusion is circular and the second protrusion is strip-shaped along the width direction of the moving contact piece, and the surfaces of the first protrusion and the second protrusion are used to be respectively attached to the surfaces of the first static contact piece and the second static contact piece.

[0011] Through the above technical solution, by setting the first protrusion and the second protrusion, it is convenient to perform high-precision turning and grinding on this part, thereby improving the fitting accuracy and conduction effect.

[0012] Optionally, a copper-nickel composite coating is cold-sprayed on the surfaces of the first static contact piece, the second static contact piece, the surface of the first protrusion and the surface of the second protrusion, and the thickness of the copper-nickel composite coating is 0.5-1.0 mm.

[0013] Through the above technical solution, the copper-nickel composite coating can reduce the contact resistance, and at the same time increase the wear resistance and oxidation resistance, so as to improve the service life of the disconnector.

[0014] Optionally, the copper-nickel composite coating is processed from copper powder and nickel powder, the powder particle sizes of the copper powder and the nickel powder are 5-25 μm, and the copper powder and the nickel powder are mixed according to a molar ratio of 9:1 or 8:2.

[0015] Optionally, from the middle to both sides along the width direction of the moving contact piece, it successively includes a first arc section and a second arc section, and the concave arc surfaces of the first arc sections of the two moving contact pieces are arranged oppositely, and the concave arc surfaces of the second arc sections of the two moving contact pieces are arranged away from each other.

[0016] Through the above technical solution, by defining the specific shape of the moving contact piece, not only the bending resistance of the moving contact piece is improved, but also the space between the two moving contact pieces and the air contact area of the moving contact piece are increased, so as to facilitate air circulation and further improve the heat dissipation effect.

[0017] Optionally, the cross-sectional area of the moving contact piece is 125-175 mm 2 .

[0018] Through the above technical solution, the larger cross-sectional area can improve the mechanical strength of the moving contact piece.

[0019] Optionally, a central hole is penetrated through the pin shaft, a through hole communicating with the central hole is vertically penetrated through the outer wall of the middle part of the pin shaft, the through hole is used for the traction wire to pass through, a strip-shaped groove communicating with the central hole is penetrated through the outer wall of the end part of the pin shaft, the strip-shaped groove extends along the length direction of the pin shaft, and the supporting rod is in sliding fit with the strip-shaped groove; the locking structure includes a first transmission pipe, a second transmission pipe, a second spring, a third spring and a transmission rod. The first transmission pipe and the second transmission pipe are both perpendicular to the moving contact piece and are coaxially arranged. The two rotating cylinders are respectively rotatably sleeved on the outer walls of the first transmission pipe and the second transmission pipe. A sliding hole is penetrated through the middle part of the moving contact piece along its own length direction. The rotating cylinders of the first transmission pipe and the second transmission pipe respectively slide through the sliding holes of the two moving contact pieces. Nuts are fixed at the separated ends of the first transmission pipe and the second transmission pipe. The two transmission rods are respectively in sliding fit with the inner walls of the first transmission pipe and the second transmission pipe. A key block is fixed on the outer wall of the transmission rod. The first transmission pipe and the second transmission pipe are penetrated with first key grooves extending along their own length directions. The key block is in sliding fit with the first key grooves. A free travel area and a second key groove are sequentially arranged on the inner wall of the rotating cylinder along its own length direction. The third spring is used to force the transmission rod to slide in a direction away from the other transmission rod and make the key block enter the second key groove from the free travel area; a sleeve is fixed at one end of the first transmission pipe, a retaining ring is fixed at the opening of the sleeve, a rotating piece which is rotatably and slidably fitted with the inner wall of the sleeve is fixed at one end of the second transmission pipe, engaging teeth are arranged on the opposite end faces of the rotating piece and the retaining ring, and the elastic force of the second spring is used to force the first transmission pipe and the second transmission pipe to move away from each other and force the engaging teeth of the rotating piece and the engaging teeth of the retaining ring to engage with each other.

[0020] With the above technical solution, during installation, the two moving contact pieces are in a separated state. Then, the moving contact pieces are flipped so that the two moving contact pieces are respectively located on both sides of the first static contact piece and the second static contact piece. At this time, the elastic force of the third spring causes the transmission rod to be in a state where its key block is engaged with the second key groove of the rotating cylinder, that is, the torques of the first transmission pipe and the second transmission pipe can be respectively transmitted to the corresponding rotating cylinders. Then, axial pressures are respectively applied to the first transmission pipe and the second transmission pipe by using two socket wrenches, so that the first transmission pipe and the second transmission pipe move axially towards each other, and the second spring is compressed, so that the engaging teeth of the rotating piece disengage from the engaging teeth of the anti-loosening ring, that is, the first transmission pipe and the second transmission pipe are made independent. Then, the two socket wrenches respectively perform rotating operations in different directions on the first transmission pipe and the second transmission pipe. The torques of the first transmission pipe and the second transmission pipe are respectively transmitted to the corresponding rotating cylinders through the key blocks of the transmission rod. The rotating directions of the two rotating cylinders are opposite and the two rotating cylinders respectively wind the corresponding traction wires. The traction wires are tightened to drive the support rod and the second sliding ring to axially slide along the direction towards the first sliding ring. The first springs on each pin shaft are all compressed, and the elastic force of the first spring is applied to the moving contact piece through the first sliding ring to force the two moving contact pieces to move towards each other and tighten, so that the moving contact pieces are respectively in close contact with the first static contact piece and the second static contact piece to complete the circuit conduction. Finally, the two socket wrenches are moved in the axially separated direction, the second spring returns to its original shape, and the first transmission pipe and the second transmission pipe move away from each other, so that the engaging teeth of the rotating piece and the engaging teeth of the anti-loosening ring are engaged, that is, the first transmission pipe and the second transmission pipe are fixed, so that the two rotating cylinders are relatively fixed, and the reaction pulling forces of the traction wires received by the two rotating cylinders are in opposite directions, and the reaction pulling forces of the two rotating cylinders cancel each other out, so as to ensure the stability of the state of the traction wire, and further ensure the stability of the position state of the two moving contact pieces.

[0021] When it is necessary to release the tightening of the moving contact piece and facilitate opening of the switch, the ends of the two transmission rods are respectively pressed so that the two transmission rods move towards each other, and the third spring is compressed. The key block slides from the second key groove of the rotating cylinder into the idle stroke area of the rotating cylinder. At this time, the first transmission pipe and the second transmission pipe have no limiting effect on the rotating cylinder. Therefore, the reaction force of the first spring on the traction wire will be transmitted to the rotating cylinder through the traction wire to realize the rotation of the rotating cylinder and the automatic unwinding of the traction wire. The first spring returns to its original shape, and the tightening force received by the moving contact piece is weakened to allow the moving contact pieces to separate and generate a gap, thereby realizing the rapid release of the tightening of the moving contact piece, which is more convenient. And, after the traction wire is unwound to an appropriate state, the transmission rod can also be released. The third spring returns to its original shape, and the third spring forces the transmission rod to slide along the direction away from the other transmission rod and makes the key block enter the second key groove from the idle stroke area, that is, the first transmission pipe and the second transmission pipe are used to brake the rotating cylinder to reduce the occurrence of excessive unwinding of the traction wire.

[0022] In summary, by providing the first transmission pipe, the second transmission pipe, the second spring, the third spring, the transmission rod, and the meshing teeth, the fixing or unfixing between the first transmission pipe and the second transmission pipe is achieved, and the fixing or unfixing between the two rotating cylinders and the first transmission pipe and the second transmission pipe respectively is achieved, so as to realize the unified winding and rapid unwinding of the traction wire, which not only improves the convenience and stability of the tightened state of the moving contact piece, but also realizes the rapid release of the tightened state of the moving contact piece.

[0023] Optionally, the through hole is a tapered hole, the large port of the tapered hole is arranged away from the central hole, three clamping pieces are arranged in the through hole of the first pin shaft, the outer surface of the clamping piece fits against the inner wall of the through hole, the clamping pieces are arranged at circumferential intervals, and an anti-detachment ring for preventing the clamping piece from detaching from the through hole is further arranged at the large port of the through hole. The side surface of the clamping piece is provided with a biting convex tooth, and the biting convex teeth of the clamping pieces are used for jointly biting the traction wire; the second sliding ring of the second pin shaft is provided with an insertion block sliding along its radial direction, and a plurality of jacks are arranged on the outer wall of the second pin shaft at equal intervals along its length direction, and the jacks are used for the insertion block to be inserted.

[0024] Through the above technical solution, after the moving contact piece is tightly installed, considering that the tightening force at the end position of the long moving contact piece may be insufficient, the first spring on the first pin shaft of the moving contact piece can be further compressed to achieve a high tightening force at the end position of the long moving contact piece and a relatively high tightening force at the non-end position of the long moving contact piece, so as to further improve the fitting stability between the static and moving contact pieces and reduce the bending deformation of the long moving contact piece. Specifically, the sliding insertion block is inserted into the jack, so that the second sliding ring is fixed to the second pin shaft, and the supporting rod on the second sliding ring cannot move. Then, a torque is applied to the two rotating cylinders again through the locking structure to further wind the traction wire. Since the supporting rod on the second pin shaft cannot move, the wound traction wire only drives the supporting rod on the first pin shaft to slide, that is, only drives the first spring on the first pin shaft to be further compressed, and the first spring on the second pin shaft is not compressed. After the first spring is compressed, the two rotating cylinders are fixed by the locking structure, and then the sliding insertion block is disengaged from the jack, so that the second sliding ring and the second pin shaft can move relatively. The over-compressed first spring on the first pin shaft will release a small part of its elastic force to drive the traction wire to move a small distance. At this time, the moving traction wire will drive the clamping pieces to wedge more tightly into the tapered hole, and the three clamping pieces will approach each other and tightly bite the traction wire to prevent the continuous movement of the traction wire, so as to maintain the compressed state of the first spring on the first pin shaft.

[0025] When it is necessary to release the tightening of the moving contact piece, a rod-shaped object can be inserted into the other through hole corresponding to the through hole where the clamping piece is located. The rod-shaped object will push the clamping piece outwards to release the wedging state between the clamping piece and the through hole, so that the traction wire is in a free state. Subsequently, the automatic unwinding of the rotating cylinder is used to realize the deformation recovery of each first spring.

[0026] In summary, by providing the clamping piece and the inserting block, the clamping piece is used to only allow the one-way movement of the traction wire, and the inserting block is used to fix the second slip ring to the second pin shaft, so that the supporting rod on the second slip ring cannot move. Therefore, the first spring on the first pin shaft of the moving contact piece can be further compressed to achieve a high tightening force at the end position of the long moving contact piece and a relatively high tightening force at the non-end position of the long moving contact piece, thereby further improving the fitting stability of the moving and static contact pieces and reducing the bending deformation of the long moving contact piece.

[0027] Optionally, a plurality of rib fins are integrally formed on the surface of the moving contact piece facing away from the other moving contact piece. Each rib fin extends along the length direction of the moving contact piece, and each rib fin is arranged at intervals along the width direction of the moving contact piece.

[0028] Through the above technical solution, by providing the rib fins, the contact area between the moving contact piece and the external air is increased, thereby greatly improving the heat dissipation effect.

[0029] The present application provides an outdoor high-voltage disconnecting switch device, and specifically adopts the following technical solutions to achieve:

[0030] An outdoor high-voltage disconnecting switch device includes a base, an insulating support, and an outdoor high-voltage disconnecting switch mechanism.

[0031] The beneficial effects of the present application are:

[0032] 1. By providing the traction wire, the supporting rod, the rotating cylinder, and the locking structure, the locking structure is used to transmit torques in different directions to the rotating cylinder respectively. The rotating cylinder rotates to tighten the traction wire, so as to compress each first spring at the same time, so that the two moving contact pieces move towards each other and are tightly tightened, making the moving contact pieces closely and stably fit with the first static contact piece and the second static contact piece respectively, which is more convenient and has strong installation stability. Secondly, by using the characteristic that the reaction pulling forces of the traction wires received by the two rotating cylinders are in opposite directions, an interlock is formed, thereby ensuring the stability of the position states of the two moving contact pieces;

[0033] 2. By providing the first transmission pipe, the second transmission pipe, the second spring, the third spring, the transmission rod, and the meshing teeth, the fixing or release of the fixing between the first transmission pipe and the second transmission pipe is realized, and the fixing or release of the fixing between the two rotating cylinders and the first transmission pipe and the second transmission pipe is realized respectively, so as to realize the unified winding and rapid unwinding of the traction wire, which not only improves the convenience and stability of the tightening state of the moving contact piece, but also realizes the rapid release of the tightening state of the moving contact piece;

[0034] 3. By setting the collet and the insert block, the collet is used to only allow the one-way movement of the traction wire, and the insert block is used to fix the second slip ring to the second pin shaft, so that the support rod on the second slip ring cannot move. Therefore, the first spring on the first pin shaft of the moving contact piece can be further compressed to achieve a high tightening force at the end position of the long moving contact piece and a relatively high tightening force at the non-end position of the long moving contact piece, thereby further improving the fitting stability of the moving and static contact pieces and reducing the bending deformation of the long moving contact piece.

[0050] Embodiment 1

[0051] Embodiment 1 discloses an outdoor high-voltage disconnector mechanism, such as Figure 1 , Figure 2 , Figure 3As shown in the figure, the outdoor high-voltage disconnector mechanism includes two moving contact pieces 1, a first static contact piece 201, a second static contact piece 202, and an elastic closing assembly. The moving contact piece 1 is strip-shaped. One end of the moving contact piece 1 is set as the hinged end, and the other end of the moving contact piece 1 is set as the opening and closing end. The hinged end of the moving contact piece 1 is hingedly connected to the first static contact piece 201, so that the moving contact piece 1 can be flipped. The opening and closing end of the moving contact piece 1 is used to contact the second static contact piece 202 to complete conduction. After the opening and closing end of the moving contact piece 1 contacts the second static contact piece 202, the elastic closing assembly is started. The elastic closing assembly will force the two moving contact pieces 1 to approach each other, so that the moving contact piece 1 is tightened to further clamp and fit the first static contact piece 201 and the second static contact piece 202, thereby improving the stability of conduction.

[0052] As Figure 2 shown, the middle to both sides of the moving contact piece 1 along its width direction sequentially include a first arc section 11 and a second arc section 12. The concave arc surfaces of the first arc sections 11 of the two moving contact pieces 1 are arranged oppositely, and the concave arc surfaces of the second arc sections 12 of the two moving contact pieces 1 are arranged away from each other. The cross-sectional area of the moving contact piece 1 is 125 - 175 mm 2 ; In this way, not only the bending resistance performance of the moving contact piece 1 is improved, but also the space between the two moving contact pieces 1 and the air contact area of the moving contact piece 1 are increased, so as to facilitate air circulation and further improve the heat dissipation effect.

[0053] And, a plurality of ribs 13 are integrally formed on the surface of the moving contact piece 1 facing away from the other moving contact piece 1. The ribs 13 extend along the length direction of the moving contact piece 1, and the ribs 13 are arranged at intervals along the width direction of the moving contact piece 1. By providing the ribs 13, the contact area between the moving contact piece 1 and the external air is increased, thereby greatly improving the heat dissipation effect.

[0054] In this embodiment, the moving contact piece 1 is machined from an aluminum alloy profile, preferably 6101, 6061 or 6063 aluminum alloy, and the first arc section 11, the second arc section 12 and the ribs 13 of the moving contact piece 1 can be integrally formed by cold extrusion, thereby improving the mechanical strength of the moving contact piece 1.

The first protrusion 14 is circular, and the second protrusion 15 is strip-shaped along the width direction of the moving contact piece 1. The surfaces of the first protrusion 14 and the second protrusion 15 are used to respectively fit the surfaces of the first static contact piece 201 and the second static contact piece 202. And, copper-nickel composite coatings are formed on the surfaces of the first static contact piece 201, the second static contact piece 202, the surface of the first protrusion 14 and the surface of the second protrusion 15 by cold spraying, and the thickness of the copper-nickel composite coating is 0.5 - 1.0 mm.

[0056] Specifically, the copper-nickel composite coating is processed from copper powder and nickel powder. The powder particle sizes of the copper powder and nickel powder are 5-25 μm, and the copper powder and nickel powder are mixed according to a molar ratio of 9:1 or 8:2.

[0057] The copper-nickel composite coating can reduce the contact resistance, while increasing the wear resistance and oxidation resistance to improve the service life of the disconnector.

The two groups of pin shafts 2 are respectively located at both ends of the moving contact piece 1 in the length direction. The two rotating cylinders 5 are located in the middle of the moving contact piece 1 in the length direction and are coaxially arranged. The pin shafts 2 and the rotating cylinders 5 are both horizontally perpendicular to the moving contact piece 1. One group of pin shafts 2 includes three pin shafts 2 arranged at intervals along the length direction of the moving contact piece 1. The pin shaft 2 farthest from the rotating cylinder 5 in one group of pin shafts 2 is named the first pin shaft 10, and the other pin shafts 2 are named the second pin shafts 20, that is, there are two first pin shafts 10 and four second pin shafts 20 in total.

[0059] The moving contact piece 1 is provided with an installation hole 16 through which the pin shaft 2 slides. The first pin shaft 10 located at the hinged end of the moving contact piece 1 also passes through the first static contact piece 201, so that the hinged end of the moving contact piece 1 is hingedly connected to the first static contact piece 201.

[0060] The pin shaft 2 is provided with a central hole 26 extending along the axial direction of the pin shaft 2. Two through holes 27 communicating with the central hole 26 are vertically penetrated through the outer wall of the middle part of the pin shaft 2. The through holes 27 extend along the radial direction of the pin shaft 2. The two through holes 27 are symmetrically arranged. The through holes 27 are tapered holes, and the large ports of the tapered holes are arranged away from the axis of the pin shaft 2.

[0061] A strip-shaped groove 25 communicating with the central hole 26 is penetrated through the outer wall of one end of the pin shaft 2. The strip-shaped groove 25 extends along the length direction of the pin shaft 2. The strip-shaped groove 25 is provided with two and is symmetrically arranged.

[0062] A limiting block 24 is fixed at one end of the pin shaft 2. A first sliding ring 21 and a second sliding ring 22 are slidably sleeved at the other end of the pin shaft 2. The first sliding ring 21 and the limiting block 24 respectively abut against the opposite surfaces of the two moving contact pieces 1 (the opposite surfaces refer to the surfaces of the two moving contact pieces 1 that face away from each other), and the limiting blocks 24 of two adjacent pin shafts 2 are respectively located on both sides of the two moving contact pieces 1, that is, the limiting blocks 24 of two adjacent pin shafts 2 are arranged in a staggered manner along the length direction of the moving contact piece 1.

[0063] The first spring 23 is sleeved on one end of the pin shaft 2. The two ends of the first spring 23 respectively abut against the opposite end faces of the first sliding ring 21 and the second sliding ring 22, and the first springs 23 of two adjacent pin shafts 2 are arranged in a staggered manner along the length direction of the moving contact piece 1.

[0064] The second slip ring 22 is fixed with a support rod 221. The length direction of the support rod 221 is the radial direction of the pin shaft 2. The support rod 221 is a round rod, and the support rod 221 is in sliding fit with the strip-shaped groove 25.

[0065] The traction wire 6 can be a high-power diamond wire or a carbon fiber wire. One end of the traction wire 6 is fixedly connected by tying to the support rod 221 of the second slip ring 22 of the first pin shaft 10. The other end of the traction wire 6 sequentially passes through the central hole 26 and the through hole 27 of the first pin shaft 10, the through holes 27 and the central holes 26 of each second pin shaft 20, and bypasses the support rod 221 of the second slip ring 22, and finally is fixedly wound around one of the drums 5. That is, each of the two drums 5 is wound and fixed with a traction wire 6, and the winding directions of the two drums 5 are opposite.

[0066] It should be noted that an avoidance groove 203 is formed in the first static contact piece 201, and the avoidance groove 203 communicates with the hole in the first static contact piece 201 through which the first pin shaft 10 passes. The traction wire 6 passes through the avoidance groove 203 to ensure that the first static contact piece 201 does not interfere with the traction wire 6 when the moving contact piece 1 deflects relative to the first static contact piece 201.

[0067] The locking structure 3 is used to transmit torque to the drum 5, and make the rotation directions of the two drums 5 opposite, and the locking structure 3 is also used to relatively fix the two drums 5. Specifically, as Figure 8 、 Figure 9 shown, the locking structure 3 includes a first transmission pipe 31, a second transmission pipe 32, a second spring 33, a third spring 35 and a transmission rod 34. The first transmission pipe 31 and the second transmission pipe 32 are both perpendicular to the moving contact piece 1 and are coaxially arranged. The two drums 5 are respectively rotatably sleeved on the outer walls of the first transmission pipe 31 and the second transmission pipe 32. A sliding hole 17 is formed through the middle of the moving contact piece 1 along its own length direction. The drums 5 of the first transmission pipe 31 and the drums 5 of the second transmission pipe 32 respectively pass through the sliding holes 17 of the two moving contact pieces 1 in a sliding manner, and the drum 5 can rotate relative to the sliding hole 17.

[0068] Nuts 311 are fixed to the separated ends of the first transmission pipe 31 and the second transmission pipe 32 (the separated ends refer to the ends of the first transmission pipe 31 and the second transmission pipe 32 that are farthest apart). The nuts 311 are located outside the moving contact piece 1. The two transmission rods 34 are respectively in axial sliding fit with the inner walls of the first transmission pipe 31 and the second transmission pipe 32. In this embodiment, the outer wall of the transmission rod 34 can be covered with a rubber coating to increase the damping of the sliding fit. A key block 341 is fixed to the outer wall of the transmission rod 34. The first transmission pipe 31 and the second transmission pipe 32 are provided with first key grooves 312 extending along their own length directions. The key block 341 is always in sliding fit with the first key grooves 312, so that the torques of the first transmission pipe 31 and the second transmission pipe 32 can be respectively transmitted to the corresponding transmission rods 34.

[0069] The inner wall of the rotary drum 5 is successively provided with an idle stroke area 52 and a second keyway 51 along its own length direction. The idle stroke area 52 can be understood as a stepped groove formed on the inner wall of the rotary drum 5, and its inner diameter is larger than the inner diameter of the inner wall of the rotary drum 5; two third springs 35 are respectively located in the first transmission pipe 31 and the second transmission pipe 32, and the end of the third spring 35 abuts against the transmission rod 34. The elastic force of the third spring 35 is used to force the transmission rod 34 to slide in a direction away from the other transmission rod 34 and make the key block 341 enter the second keyway 51 from the idle stroke area 52. That is, under normal conditions, the key blocks 341 cooperate with the first keyway 312 and the second keyway 51 together, so that the torque of the first transmission pipe 31 and the second transmission pipe 32 can be transmitted to the corresponding rotary drum 5. When the two transmission rods 34 slide towards each other under the action of an external force (the third spring 35 is compressed), the key blocks 341 of the transmission rods will enter the idle stroke area 52 from the second keyway 51, and there is no torque transmission relationship between the rotary drum 5 and the first transmission pipe 31 and the second transmission pipe 32. That is, the rotary drum 5 is in a freely rotatable state.

[0070] In other embodiments, the second keyway 51 can be provided with multiple ones and arranged at intervals along the circumferential direction of the rotary drum 5.

[0071] A sleeve 36 is fixed at one end of the first transmission pipe 31, and a retaining ring 37 is fixed at the mouth of the sleeve 36, which can be fixed by welding; a rotating piece 38 located in the sleeve 36 is fixed at one end of the second transmission pipe 32. The rotating piece 38 is axially slidably matched with the inner wall of the sleeve 36 and rotationally matched with the inner wall of the sleeve 36. A plurality of engaging teeth 371 are fixed on the opposite end faces of the rotating piece 38 and the retaining ring 37, and the engaging teeth 371 are arranged at intervals in the circumferential direction; the second spring 33 is located in the sleeve 36, and the two ends of the second spring 33 respectively abut against the inner end face of the sleeve 36 and the end face of the rotating piece 38. The elastic force of the second spring 33 is used to force the first transmission pipe 31 and the second transmission pipe 32 to move away from each other and force the engaging teeth 371 of the rotating piece 38 and the engaging teeth 371 of the retaining ring 37 to engage with each other.

[0072] During installation, the two moving contact pieces 1 are in a separated state. At this time, the first spring 23 is not compressed or is slightly compressed to ensure that there is enough clearance between the two moving contact pieces 1. Then, turn over the moving contact pieces 1 so that the two moving contact pieces 1 are respectively located on both sides of the first static contact piece 201 and the second static contact piece 202. At this time, the elastic force of the third spring 35 causes the transmission rod 34 to be in a state where its key block 341 is engaged with the second key groove 51 of the rotating cylinder 5, that is, the torques of the first transmission pipe 31 and the second transmission pipe 32 can be respectively transmitted to the corresponding rotating cylinder 5. Then, use two socket wrenches to apply axial pressure to the first transmission pipe 31 and the second transmission pipe 32 respectively, so that the first transmission pipe 31 and the second transmission pipe 32 move axially towards each other, and the second spring 33 is compressed, so that the engaging teeth 371 of the rotating piece 38 disengage from the engaging teeth 371 of the anti-detachment ring 37, that is, the first transmission pipe 31 and the second transmission pipe 32 are independent of each other (at this time, the key block 341 of the transmission rod 34 is still engaged with the second key groove 51 of the rotating cylinder 5). Then, the two socket wrenches are respectively used to perform rotational operations in different directions on the first transmission pipe 31 and the second transmission pipe 32. The torques of the first transmission pipe 31 and the second transmission pipe 32 are respectively transmitted to the corresponding rotating cylinder 5 through the key block 341 of the transmission rod 34. The rotating directions of the two rotating cylinders 5 are opposite, and the two rotating cylinders 5 respectively wind up the corresponding traction lines 6. The traction lines 6 are tightened to drive the support rod 221 and the second slip ring 22 to axially slide in the direction towards the first slip ring 21, so that the first springs 23 on each pin 2 are all compressed. The elastic force of the first spring 23 is applied to the moving contact piece 1 through the first slip ring 21 to force the two moving contact pieces 1 to move towards each other and tighten, so that the moving contact pieces 1 are respectively in close contact with the first static contact piece 201 and the second static contact piece 202 to complete the circuit conduction.

[0073] Finally, move the two socket wrenches in the axially separated direction. The second spring 33 resumes deformation, and the first transmission pipe 31 and the second transmission pipe 32 move away from each other, so that the engaging teeth 371 of the rotating piece 38 and the engaging teeth 371 of the anti-detachment ring 37 are engaged, that is, the first transmission pipe 31 and the second transmission pipe 32 are fixed, so that the two rotating cylinders 5 are relatively fixed, and the reaction pulling force directions of the traction lines 6 received by the two rotating cylinders 5 are opposite, and the reaction pulling forces of the two rotating cylinders 5 cancel each other out, so as to ensure the stability of the state of the traction line 6, and further ensure the stability of the position states of the two moving contact pieces 1.

[0074] When it is necessary to release the tightening of the moving contact piece 1 and facilitate the opening of the switch, the ends of the two transmission rods 34 are respectively pressed, so that the two transmission rods 34 move towards each other, the third spring 35 is compressed, and the key block 341 slides from the second key groove 51 of the rotating cylinder 5 into the idle stroke area 52 of the rotating cylinder 5. At this time, the first transmission pipe 31 and the second transmission pipe 32 have no limiting effect on the rotating cylinder 5, and the rotating cylinder 5 is in a freely rotatable state. Therefore, the reaction force of the first spring 23 on the traction wire 6 will be transmitted to the rotating cylinder 5 through the traction wire 6 to realize the rotation of the rotating cylinder 5 and the automatic unwinding of the traction wire 6. The first spring 23 resumes deformation, and the tightening force on the moving contact piece 1 is weakened, allowing the moving contact piece 1 to move apart and generate a gap, thereby realizing the rapid release of the tightening of the moving contact piece 1, which is more convenient.

[0075] In summary, by setting the first transmission pipe 31, the second transmission pipe 32, the second spring 33, the third spring 35, the transmission rod 34 and the meshing teeth, the fixation or release of the fixation between the first transmission pipe 31 and the second transmission pipe 32 is realized, and the fixation or release of the fixation between the two rotating cylinders 5 and the first transmission pipe 31 and the second transmission pipe 32 is realized, so as to realize the unified winding and rapid unwinding of the traction wire 6. This not only improves the convenience and stability of the tightening state of the moving contact piece 1, but also realizes the rapid release of the tightening state of the moving contact piece 1.

[0076] Embodiment 1 also discloses an outdoor high-voltage disconnector device, which includes a base, an insulating support and an outdoor high-voltage disconnector mechanism.

[0077] Embodiment 2

[0078] The difference between Embodiment 2 and Embodiment 1 is that, as Figure 10 、 Figure 11 shown, three clamping pieces 271 are arranged in the through hole 27 of the first pin shaft 10. The outer surface of the clamping piece 271 fits against the inner wall of the through hole 27. The clamping pieces 271 are arranged at circumferential intervals. The three clamping pieces 271 are combined into a conical structure. The side surface of the clamping piece 271 is provided with a biting convex tooth 272. The biting convex teeth 272 of the clamping pieces 271 are used to jointly bite the traction wire 6.

[0079] A retaining ring 273 for preventing the clamping piece 271 from detaching from the through hole 27 is also fixedly welded to the large port of the through hole 27. The inner diameter of the retaining ring 273 is smaller than the outer diameter of the virtual circle surrounded by the clamping pieces 271. The retaining ring 273 is used to prevent the clamping piece 271 from detaching.

[0080] As Figure 12 shown, a plug block 28 is slidably arranged along the radial direction of the second sliding ring 22 of the second pin shaft 20. A plurality of jacks (not marked in the figure) are arranged at equal intervals along the length direction of the outer wall of the second pin shaft 20. The jacks are used for the plug block 28 to be inserted.

[0081] After the moving contact piece 1 is tightly installed, considering the possible insufficient tightening force at the end position when the moving contact piece 1 has a large length, the first spring 23 on the first pin shaft 10 of the moving contact piece 1 can be further compressed to achieve a high tightening force at the end position of the moving contact piece 1 with a large length and a relatively high tightening force at the non-end position of the moving contact piece 1 with a large length, thereby further improving the fitting stability of the moving and static contact pieces and reducing the occurrence of bending deformation of the moving contact piece 1 with a large length.

[0082] The specific operation is as follows: after the moving contact piece 1 is tightly installed, insert the sliding insert block 28 into the jack, fix the second sliding ring 22 to the second pin shaft 20, so that the support rod 221 on the second sliding ring 22 cannot move, and then apply torque to the two rotating cylinders 5 again through the locking structure 3 to further wind up the traction wire 6. Since the support rod 221 on the second pin shaft 20 cannot move, the wound traction wire 6 only drives the support rod 221 on the first pin shaft 10 to slide, that is, only drives the first spring 23 on the first pin shaft 10 to be further compressed, and the first spring 23 on the second pin shaft 20 is not compressed. That is, the compression degree of the first spring 23 of the first pin shaft 10 is greater than the compression degree of the first spring 23 of the second pin shaft 20. After the first spring 23 of the first pin shaft 10 is compressed, use the locking structure 3 to fix the two rotating cylinders 5, and then the sliding insert block 28 disengages from the jack, so that the second sliding ring 22 and the second pin shaft 20 can move relative to each other. The overly compressed first spring 23 on the first pin shaft 10 will release a small part of its elastic force to drive the traction wire 6 to move a small distance. At this time, the moving traction wire 6 will drive the clamping pieces 271 to wedge more tightly into the tapered hole. The three clamping pieces 271 approach each other and tightly bite the traction wire 6 to prevent the continued movement of the traction wire 6, thereby maintaining the compressed state of the first spring 23 on the first pin shaft 10.

[0083] When it is necessary to release the tightening of the moving contact piece 1, a rod-shaped object can be inserted into the corresponding other through hole 27 of the through hole 27 where the clamping piece 271 is located. The rod-shaped object will poke the clamping piece 271 outward to release the wedging state between the clamping piece 271 and the through hole 27. The adjacent clamping pieces 271 are separated to release the clamping of the traction wire 6, so that the traction wire 6 is in a free state. Subsequently, the automatic unwinding of the rotating cylinder 5 is used to realize the restoration of the deformation of each first spring 23.

[0084] In summary, by providing the collet 271 and the insertion block 28, the collet 271 is configured to allow only unidirectional movement of the traction wire 6, and the insertion block 28 is configured to fix the second slip ring 22 to the second pin shaft 20, preventing the support rod 221 on the second slip ring 22 from moving. Therefore, the first spring 23 on the first pin shaft 10 of the moving contact piece 1 can be further compressed, while the first springs 23 of the other second pin shafts 20 are not compressed, so as to achieve a high tightening force at the end position of the long moving contact piece 1 and a relatively high tightening force at the non-end position of the long moving contact piece 1, thereby further improving the fitting stability of the moving and static contact pieces and reducing the occurrence of bending deformation of the long moving contact piece 1.

Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application.
