Description

Technical Field

[0001] The invention relates to the field of isolating switches, in particular to an inflatable isolating switch. Background Art

[0002] Inflatable disconnectors are usually installed in inflatable cabinets, and mainly include static contacts, moving contacts, transmission components, inflatable chambers, and related control and protection components. Static contacts and moving contacts are the key parts to achieve circuit disconnection and closure. The transmission components are used to drive the moving contacts to move, the inflatable chambers are used to fill with insulating gas to ensure insulation performance, and the control and protection components ensure the safe and reliable operation of the disconnectors. Inflatable disconnectors usually have complete interlocking and protection devices to prevent misoperation and accidental closing, and ensure the safety of operators and equipment. In addition, gas insulating media are not easy to burn or explode, which improves the safety of the equipment.

[0003] At present, inflatable isolating switches usually have two-position load switches or three-position load switches. The three-position load switches have closing position, opening position, and line-side grounding position, respectively, while the two-position load switches do not have line-side grounding positions. Therefore, in specific applications, it is necessary to select the appropriate one based on the usage background. However, the existing inflatable isolating switches are designed with several specific position load switches before leaving the factory. As a result, in subsequent use, if the usage background changes and it is necessary to switch to the use of a two-position load switch or a three-position load switch, it cannot be done. Only a new inflatable isolating switch can be customized, which will reduce the functionality of the inflatable isolating switch and increase the cost.

[0004] Meanwhile, the existing inflatable isolating switches need to be sealed and then filled with sulfur hexafluoride (SF6) gas after installation, so when connecting the conductive terminals on the circuit breaker with the conductive terminals on the side expansion busbar, the space is cramped and the installation is inconvenient. Therefore, an inflatable isolating switch is proposed. Summary of the invention

[0017] Compared with the related art, the inflatable isolating switch provided by the present invention has the following beneficial effects:

[0018] 1. The present invention sets a circular ring in one of the three isolating switch frames, and sets the other two as spline rings with spline shaft sleeves. In this way, the telescopic member drives the mounting plate to move downward, and when the fixed bevel block is driven to move downward, the fixed rings and sleeve rings on both sides are pushed to approach each other, so that each key slot moves away from each other and cancels the engagement with the spline shaft. At this time, the isolating switch knife switch on the circular ring is in the open state, and the grounding terminal on the mounting plate moves down to the bottom where the isolating switch knife switches on the other two spline rings cannot contact, so that the three-position state can be switched to the two-position state, thereby improving the functionality;

[0020] 3. The present invention can achieve stability during installation of the isolating switch frame by arranging a slide rail to drive the plug rod to be inserted into the slide opening of each isolating switch frame. When the plug rod is inserted into the slide opening, it can also push the limiting inclined block to move upward, and push the movable terminal upward through the top block to contact and conduct electricity with the fixed terminal. At the same time, the upward movement of the movable terminal can move to a position corresponding to the side expansion mother coupling terminal on one side, which also facilitates its conductive connection with the side expansion mother coupling on one side, and facilitates the conductive installation connection of the inflatable isolating switch.

[0035] Further, a telescopic member 7 is installed on the base 1, and an L-shaped plate 26 is connected to the telescopic member 7, and a mounting plate 8 is connected through the L-shaped plate 26. The mounting plate 8 is installed with a grounding terminal 9 that is inserted into each of the isolating switch blades 5.

[0036] Furthermore, a limit rail 28 is connected to the base 1, and a guide rail groove 27 is provided on the isolating switch frame 2. The limit rail 28 is slidably connected in the guide rail groove 27. A support block 29 is connected to one side of each limit rail 28.

If necessary, bolts can be installed between the limit guide rail 28 and the guide rail groove 27 to improve the stability of the installation of the isolating switch frame 2.

[0037] Further, the driving assembly 1 includes a guide rod 13, a slide 14, a support frame 16, and a guide slide rod seat 17. The guide rod 13 array is connected to the inner wall of the ring 11, the slide 14 is slidably sleeved on the guide rod 13, the key slot 15 is connected to the slide 14, the support frame 16 is connected to both sides of the disconnector frame 2, the guide slide rod seat 17 is connected to the support frame 16, the fixed ring 19 is slidably sleeved on the guide slide rod seat 17, the two sides of the fixed ring 19 are connected with moving inclined blocks 23, and the mounting plate 8 is connected with a fixed inclined block 25 that fits and slides with the moving inclined block 23, as shown in FIG. Figure 4 , 6 As shown, when it is necessary to switch the original three-station load state to the two-station load state, the driving mounting plate 8 is moved downward, which can drive the fixed bevel block 25 to move downward, and squeeze and push the movable bevel blocks 23 on both sides to slide close to each other on their respective guide slide rod seats 17, drive the rotating plate 22 to rotate, and push each keyway 15 and the spline shaft 10 away from each other, and cancel the engagement with the spline shaft 10. At this time, the rotation of the spline shaft 10 can only drive the isolating switch blades 5 on the other two spline rings 4 to rotate, and cannot control the isolating switch blades 5 on the ring 11. At this time, the grounding terminal 9 is on the lower side, and the isolating switch blade 5 on the spline ring 4 cannot contact the grounding terminal 9 sleeve no matter which station it is in.

[0038] Furthermore, sleeves 12 are symmetrically connected to both sides of the ring 11 axially, and guide rods 13 are connected to the inner wall of the sleeve 12 along the radial array of the sleeve 12. The sleeve 12 and the ring 11 are connected and coaxial. Figure 7 As shown, the arrangement of the sleeve 12 enables the slide 14 to drive the keyway 15 to have a larger adjustment range.

[0039] Further, the outer side of the guide slide rod seat 17 is sleeved with a spring 20, and the two ends of the spring 20 are respectively connected to the fixed ring 19 and the support frame 16, the two sides of the fixed ring 19 are connected to the side plates 18, and the side plates 18 are slidably sleeved with the guide rod 13, the moving inclined block 23 is connected to the side plate 18, the mounting plate 8 is connected to the mounting frame 24 on both axial sides of the ring 11, and the fixed inclined block 25 is connected to the mounting frame 24, as shown in FIG. Figure 7 , 8 As shown, the side plate 18 is provided to facilitate the connection with the movable bevel block 23, and the spring 20 is provided to facilitate the reset of the side plate 18 and the fixed ring 19 in the absence of external force.

[0040] Furthermore, an installation frame 34 is connected to the isolating switch frame 2, a circuit breaker 35 is installed in the installation frame 34, and fixed terminals 36 are connected to both sides of the circuit breaker 35, the lower end of the circuit breaker 35 is connected to the isolating switch knife seat 6 that is clamped with the isolating switch knife 5, and moving terminals 39 are also slidably connected to both sides of the installation frame 34. A driving component 2 is provided on the isolating switch frame 2, and the driving component 2 is used to drive the moving terminal 39 to contact the fixed terminal 36.

[0041] Furthermore, the second driving component includes a slideway opening 30, a limiting inclined block 31, a top block 33, a bracket 37, and a second guide slide rod seat 38. The slideway opening 30 is opened on the isolating switch frame 2, the limiting inclined block 31 is slidably connected in the slideway opening 30, and slides through and extends to the top of the isolating switch frame 2, and is connected to a slide frame 32 at the extended end, the top block 33 is connected to the slide frame 32, the bracket 37 is connected to the isolating switch frame 2, the second guide slide rod seat 38 is connected to the bracket 37, the moving terminal 39 is slidably sleeved on the outside of the second guide slide rod seat 38, and cooperates with the upper end of the top block 33, and the base 1 is slidably connected with a plug rod 44 inserted in cooperation with the slideway opening 30, and the plug rod 44 fits and slides with the limiting inclined block 31, such as Figure 1 , 4 As shown in Figure 9, after each isolating switch frame 2 is installed on the limit guide rail 28, the insertion rod 44 can be controlled to cooperate with the slide opening 30 for insertion, so as to further stabilize the isolating switch frame 2. During the insertion process, the insertion rod 44 will push the limit bevel block 31 upward, and push the slide frame 32 and the top block 33 upward to resist the moving terminal 39 from moving upward and contacting and conducting with the fixed terminal 36.

[0042] Furthermore, a slide rail 40 is installed on one side of the base 1, a connecting pipe 42 is slidably connected to the slide rail 40, and one end of the connecting pipe 42 is connected to a mounting seat 43, and a plug rod 44 is connected to the mounting seat 43, such as Figure 4 As shown, the insertion of the insertion rod 44 can be achieved through the slide rail 40, and the slide rail 40 can adopt the existing screw guide rail, linear roller guide roller, etc., and the connecting tube 42 is a hollow square tube to reduce the structural weight.

[0043] Furthermore, a motor 45 is mounted on the mounting seat 43, and the output end of the motor 45 is connected to the spline shaft 10. The mounting seat 43 is also rotatably connected to a circuit breaker control shaft 41. Figure 1 and 4 As shown, the motor 45 is a servo motor, which can accurately control the rotation angle of the spline shaft 10 , and the circuit breaker control shaft 41 can control the circuit breaker 35 .

[0044] Working principle: In specific use, it is generally in the three-position load switch state. When it needs to be adjusted to the two-position load switch state, the motor 45 first drives the spline shaft 10 to drive the spline ring 4 and the circular ring 11 to rotate to the open state, and then controls the telescopic member 7 to extend, pushes the mounting plate 8, the grounding terminal 9 and the fixed bevel block 25 to move downward, and through the cooperation of the fixed bevel block 25 and the moving bevel block 23, squeezes the fixed ring 19 and the sleeve ring 21 on both sides of the circular ring 11 to get close to each other, and compresses the spring 20 to push the rotating plate 22 to rotate, driving the key slots 15 to slide away from each other. Cancel the clamping sleeve with the spline shaft 10. After that, the rotation of the spline shaft 10 will not be able to control the ring 11, and at this time the ring 11 and the isolating switch knife 5 thereon will remain in the open state under the action of damping, while the isolating switch knife 5 on the spline ring 4 in the other two isolating switch frames 2 will continue to be driven by the spline shaft 10 to the closing position or the open position, and even if the isolating switch knife 5 on the spline ring 4 is rotated to the grounding position, the grounding terminal 9 is already below it at this time, and contact conduction cannot be achieved, thereby switching from the three-position load switch to the two-position load switch;

[0045] When the isolating switch frame 2 needs to be disassembled, the slide rail 40 drives the plunger 44 to cancel the insertion with the corresponding slideway opening 30 of the isolating switch frame 2, so that the isolating switch frame 2 can be conveniently pulled out directly from the limit guide rail 28. At this time, since the plunger 44 cancels the limit with the limit inclined block 31, under the action of gravity, the limit inclined block 31 will drive the top block 33 to move downward, and cancel the resistance to the moving terminal 39, so as to realize the separation of the moving terminal 39 and the fixed terminal 36. Conversely, during installation, This is the case. At this time, the plug rod 44 will push the limit bevel block 31 and the top block 33 upward, and push the movable terminal 39 to contact the fixed terminal 36 for electrical conduction. In the process of movement, the plug rod 44 will also drive the spline shaft 10 to move, so as to cancel the clamping sleeve with the corresponding spline ring 4 or circular ring 11 in the disconnector frame 2, which facilitates the removal and replacement of the disconnector frame 2, and also facilitates the connection between the movable terminal 39 and the fixed terminal 36 in a small space, and at the same time facilitates the conductive connection between the movable terminal 39 and the side expansion busbar.
