Description

Technical Field

[0001] This utility model relates to the field of high-voltage disconnecting switch technology, and in particular to a rotary high-voltage disconnecting switch. Background Technology

[0002] A high-voltage disconnect switch is a type of switching device in a power system used to disconnect circuits during equipment maintenance or emergencies. It is mainly used in high-voltage transmission lines and substations to provide safety isolation and circuit switching. It does not have the ability to interrupt load current or short-circuit current and needs to be used in conjunction with other circuit breaking devices. It achieves circuit switching through mechanical operation, thus ensuring the safe operation of the power system.

[0003] Existing rotary high-voltage disconnect switches lack effective limiting measures after closing, making it difficult to ensure the stability of the closed state. In complex environments such as outdoors, high-voltage disconnect switches are susceptible to natural factors such as strong winds and vibrations. These external forces may cause the contacts to shift or loosen after closing, leading to tripping. Tripping not only interrupts the power supply and affects the normal operation of the power system, but may also damage equipment and even cause safety accidents. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that existing rotary high-voltage disconnect switches lack effective limiting measures after closing, and to propose a rotary high-voltage disconnect switch.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A rotary high-voltage disconnect switch includes a base on which insulating porcelain pillars are symmetrically mounted, and the insulating porcelain pillars are equipped with a connection mechanism capable of energizing and de-energizing.

[0007] The connecting mechanism includes a first connecting rod fixedly installed on one of the insulating ceramic pillars, and a second connecting rod rotatably installed on the other insulating ceramic pillar. Limiting components and switching components are assembled on the first and second connecting rods.

[0008] As a further description of the above technical solution:

[0009] The limiting component includes a rotating block rotatably mounted on the top of the first connecting rod. A connector strip is inserted into the interior of the rotating block. A mounting bracket is fixedly mounted on the top of the connector strip. A plug rod is inserted into the mounting bracket. A first spring is sleeved on the surface of the plug rod and at the bottom of the mounting bracket. A plug hole is opened on one side of the first connecting rod.

[0010] As a further description of the above technical solution:

[0011] The plug strip is rotatably mounted on the second connecting rod, one end of the plug rod extends to the outside of the plug strip, the size of the plug hole is adapted to the plug rod, and a torsion spring is installed at the connection between the rotating block and the first connecting rod.

[0012] As a further description of the above technical solution:

[0013] The switching assembly includes a slot on one side of the first connecting rod, with second springs symmetrically installed inside the slot, a first contact piece fixedly installed between the two second springs, a locking block fixedly installed at one end of the second connecting rod, and rubber sheets fixedly installed on the inclined surfaces on both sides of the locking block.

[0014] As a further description of the above technical solution:

[0015] The size of the card slot is adapted to the card block, and a second contact piece is fixedly installed on one side of the card block. The size of the first contact piece is adapted to the second contact piece.

[0016] As a further description of the above technical solution:

[0017] An arc-shaped groove is provided on the base, and an extension rod is fixedly installed at the bottom end of the second connecting rod between the arc-shaped grooves. A ring and a connector are rotatably installed on the extension rod.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] When the second connecting rod is closed, the rotating block can rotate and reset via the torsion spring. At the same time, it will also drive the plug bar to rotate and reset to a horizontal state. At this time, the plug bar is aligned with the plug hole again. The reaction force of the first spring causes the plug bar to be inserted into the plug hole, thereby limiting the first and second connecting rods and preventing the first and second connecting rods from being unstable due to wind or vibration. When the locking block and the locking slot are closed, the inclined surface on the locking slot will squeeze the rubber sheet on the locking block. The pressure on the rubber sheet increases the friction between the locking block and the locking slot, thereby increasing the stability between the locking block and the locking slot.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figure 1 - Figure 6 As shown, the present invention provides a rotary high-voltage disconnect switch, including a base 10, on which insulating porcelain pillars 20 are symmetrically mounted, and on which a connecting mechanism 30 capable of energizing and de-energizing is assembled.

[0032] The connecting mechanism 30 includes a first connecting rod 31 fixedly installed on one of the insulating porcelain pillars 20, and a second connecting rod 32 rotatably installed on the other insulating porcelain pillar 20. The first connecting rod 31 and the second connecting rod 32 are equipped with a limit component 33 and a switching component 34. The limit component 33 can prevent the first connecting rod 31 and the second connecting rod 32 from disengaging from the closed circuit, and the switching component 34 can make the second connecting rod 32 rotate. The closing and disconnection are achieved by rotating the second connecting rod 32.

[0033] like Figure 3 - Figure 4As shown, the limiting component 33 includes a rotating block 331 rotatably mounted on the top of the first connecting rod 31. A connector strip 332 is inserted into the interior of the rotating block 331. The connector strip 332 can move within the rotating block 331. A mounting bracket 333 is fixedly mounted on the top of the connector strip 332. A plug rod 334 is inserted into the mounting bracket 333. A first spring 335 is sleeved on the surface of the plug rod 334 and at the bottom of the mounting bracket 333. The plug rod 334 can be reset by the reaction force of the first spring 335. A plug hole 336 is opened on one side of the first connecting rod 31.

[0034] In more detail, the plug strip 332 is rotatably mounted on the second connecting rod 32, one end of the plug rod 334 extends to the outside of the plug strip 332, and the size of the plug hole 336 is adapted to the plug rod 334 so that the plug rod 334 can be inserted into the plug hole 336. A torsion spring is installed at the connection between the rotating block 331 and the first connecting rod 31, and the rotating block 331 can be reset by the torsion spring.

[0035] When the second connecting rod 32 rotates, it will also pull the plug strip 332. While the plug strip 332 rotates through the rotating shaft, it will also move inside the rotating block 331. At this time, the rotating block 331 will also rotate into an inclined state due to the movement of the plug strip 332. The inclined state of the rotating block 331 is consistent with that of the plug strip 332. When the plug strip 332 moves, the position of the plug rod 334 will also change. At this time, the plug rod 334 will be squeezed by the edge of the socket 336 and move towards the inside of the plug strip 332, thereby disengaging from the socket 336.

[0036] When the second connecting rod 32 is closed, the rotating block 331 can rotate and reset through the torsion spring. At the same time, it will also drive the plug bar 332 to rotate and reset to a horizontal state. At this time, the plug bar 334 will once again correspond to the plug hole 336. The reaction force of the first spring 335 will cause the plug bar 334 to be inserted into the plug hole 336, thereby limiting the first connecting rod 31 and the second connecting rod 32 and preventing the first connecting rod 31 and the second connecting rod 32 from disengaging due to wind or vibration.

[0037] like Figure 5 - Figure 6 As shown, the on / off assembly 34 includes a slot 341 formed on one side of the first connecting rod 31. Second springs 342 are symmetrically installed inside the slot 341. A first contact piece 343 is fixedly installed between the two second springs 342. A locking block 344 is fixedly installed at one end of the second connecting rod 32. Rubber sheets 345 are fixedly installed on the inclined surfaces on both sides of the locking block 344.

[0038] In more detail, the size of the card slot 341 is adapted to the card block 344, and a second contact piece is fixedly installed on one side of the card block 344. The size of the first contact piece 343 is adapted to the second contact piece.

[0039] When the first connecting rod 31 and the second connecting rod 32 are combined, the locking block 344 will also be combined with the locking slot 341. At this time, the inclined surfaces on the locking block 344 and the locking slot 341 will compress the rubber sheet 345 on the locking block 344. The compressed rubber sheet 345 increases the friction between the locking block 344 and the locking slot 341, increasing the stability between the locking block 344 and the locking slot 341. At the same time, when the locking block 344 is combined, the second contact piece on its surface will also come into contact with the first contact piece 343 and compress the first contact piece 343. The first contact piece 343 can always maintain a close contact with the second contact piece through the reaction force of the second spring 342. The contact between the second contact piece and the first contact piece 343 forms a closed state, thereby realizing the power supply.

[0040] In more detail, the base 10 has an arc-shaped groove. An extension rod is fixedly installed at the bottom of the second connecting rod 32, located between the arc-shaped grooves. A ring and a connector are rotatably mounted on the extension rod. The connector is a snap-fit, as is common in the prior art. When the entire device is at a high position, it is connected to the ring at the bottom of the extension rod via an external insulating device. The ring and extension rod also allow movement of the second connecting rod 32. If the two sets of devices need to be synchronously closed or opened, the connector is rotated to engage with the extension rod of the other set of devices. Pushing the extension rod on one set of devices allows the two sets of extension rods to move synchronously through the connector, thus achieving the opening and closing of the two sets of devices (e.g., ...). Figure 2 (As shown).

[0041] Working principle: In use, by rotating the second connecting rod 32 and merging it with the first connecting rod 31, the locking block 344 will also merge with the slot 341. At this time, the inclined surfaces on the locking block 344 and the slot 341 will compress the rubber sheet 345 on the locking block 344. The compressed rubber sheet 345 increases the friction between the locking block 344 and the slot 341, increasing the stability between the locking block 344 and the slot 341. At the same time, when the locking block 344 merges, the second contact piece on its surface will also contact the first contact piece 343 and compress the first contact piece 343. The first contact piece 343 can always maintain a close contact with the second contact piece through the reaction force of the second spring 342. The contact between the second contact piece and the first contact piece 343 forms a closed state, thereby realizing the power supply.

[0042] When the second connecting rod 32 is combined, the rotating block 331 can rotate and reset through the torsion spring. At the same time as resetting, it will also drive the plug strip 332 to rotate and reset to a horizontal state. At this time, the plug rod 334 is aligned with the plug hole 336 again. The reaction force of the first spring 335 causes the plug rod 334 to be inserted into the plug hole 336, thereby limiting the first connecting rod 31 and the second connecting rod 32 and preventing the first connecting rod 31 and the second connecting rod 32 from separating due to wind or vibration.

[0043] When the entire device is located at a high position, it is connected to the ring at the bottom of the extension rod through an external insulating device. The second connecting rod 32 can also be moved through the ring and the extension rod. If the two sets of devices need to be closed or closed synchronously, the connecting piece is engaged with the extension rod of the other set of devices by rotating the connecting piece. At this time, by pushing the extension rod on one set of devices, the two sets of extension rods can be moved synchronously through the action of the connecting piece, thereby realizing the opening and closing of the two sets of devices.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
