Description

Technical Field

[0001] The present invention relates to the technical field of disconnectors, and specifically to a manual operating mechanism for a disconnector. Background Art

[0002] A disconnector is a switching device mainly used for "isolating power sources, performing switching operations, and connecting and disconnecting small-current circuits" without arc-extinguishing function. When the disconnector is in the open position, there is an insulating distance that meets the specified requirements and an obvious disconnection mark between the contacts; when in the closed position, it is a switching device that can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time.

[0003] The invention patent with the publication number CN114188177A discloses a 40.5 kV vertically-opening disconnector, which includes a chassis, on which multiple pairs of support insulators and main conductive bases are arranged side by side. It also includes a transmission box, a double-layer conductive arm, a transmission insulator, and a driving mechanism. The transmission crank arm is used to control the rotation of the transmission insulator to control the vertical opening and closing actions of the double-layer conductive arm and the static-side base. It has high current-carrying capacity. The conductive arm of this type of disconnector adopts a double-layer conductive arm structure, and the cross-sectional area of each layer of the conductive arm is small, which can effectively solve the problem of difficult selection of conductive materials for large current parameters above 6300 kA; the operation is flexible, controllable, and stable, reducing the impact on the static side during closing, and can stop at any position and has a certain static holding force; it is convenient to maintain. The electric mechanism of the disconnector has a simple structure, can be used in harsh environments such as dusty and humid conditions, and is convenient for daily maintenance.

[0004] However, the operating mechanism of the above invention is complex, and the disconnector cannot be manually operated. Using a motor for operation is not safe. Once the motor fails due to high voltage electricity or other reasons, the disconnector will not be able to work. Therefore, a manually-operated disconnector that can be safely operated is needed.

Detailed implementation manners

[0024] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation manners.

[0025] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown in, the present invention provides a technical solution: a manual operating mechanism for a disconnector, including a housing assembly 1, a switch assembly 2, a main knife switch assembly 3, and a transmission assembly 4. The switch assembly 2 is fixedly installed on the housing assembly 1. The housing assembly 1 is fixedly installed with a main knife switch assembly 3, a transmission assembly 4, and an earthing knife switch assembly 5. The housing assembly 1 includes a main knife switch 103 and a control rod housing 104. The main knife switch 103 is fixedly connected to an insulator 102. The switch assembly 2 includes a control rod 201. The control rod 201 is fixedly and slidably connected to a switch slide rod 202. The switch slide rod 202 is fixedly connected to the control rod housing 104. The main knife switch assembly 3 includes a rotating shaft 301. The rotating shaft 301 is rotatably connected to a main body bracket 101. An insulator 102 is fixedly connected to the rotating shaft 301. The transmission assembly 4 includes a transmission Z-shaped rod 412. The transmission Z-shaped rod 412 is slidably connected to a transmission cross bracket 411. The transmission cross bracket 411 is fixedly installed on the main body bracket 101. The earthing knife switch assembly 5 includes an earthing knife switch 505. The earthing knife switch 505 is rotatably connected to the first end of an earthing knife switch ring rod 504. The earthing knife switch ring rod 504 is rotatably connected to the main body bracket 101. By pulling the control rod 201, the rotating shaft 301 is rotated, thereby driving the insulator 102 and the main knife switch 103 to rotate, realizing the function of opening the main knife switch. When the main knife switch rotates by 90 degrees, the restriction on the earthing knife switch 505 is released, and the earthing knife switch 505 is lifted by driving the transmission Z-shaped rod 412, thereby realizing the function of closing the earthing knife switch.

[0026] As Figure 1 、 Figure 2 and Figure 3 shown, the present invention is provided with multiple groups of main knife switches 103 and their corresponding rotating shafts 301, earthing knife switches 505 and other related structures.

[0027] The switch assembly 2 further includes a switch pull rod 203. The first end of the switch pull rod 203 is slidably connected to a groove on the control rod 201. The second end of the switch pull rod 203 is rotatably connected to the control rod housing 104. The control rod housing 104 is further rotatably connected to a second switch connecting rod 205. The first end of the second switch connecting rod 205 is slidably connected to a groove on the switch pull rod 203. The second end of the second switch connecting rod 205 is provided with a shaft, and this shaft is slidably connected to a groove on a switch buffer rod 206. The first end of the second switch connecting rod 205 is rotatably connected to a switch connecting rod 204. The second end of the second switch connecting rod 205 is rotatably connected to a switch linkage rod 210.

[0028] The switch assembly 2 further includes a switch drive rod 207. The first end of the switch drive rod 207 is rotatably connected to the first end of the switch buffer rod 206. The first end of the switch buffer rod 206 is fixedly connected to the first end of a switch spring 208. The second end of the switch spring 208 is fixedly connected to a switch buffer ring 209. The switch buffer ring 209 is also slidably connected to the second end of the switch buffer rod 206.

[0029] As Figure 4 、 Figure 5 and Figure 6 shown, when in use, pressing the control rod 201 causes the control rod 201 to drive the switch pull rod 203 to rotate. When the switch pull rod 203 rotates, it drives the switch second connecting rod 205 to rotate. The switch second connecting rod 205 drives the switch linkage rod 210 and the switch buffer rod 206 to move upward. The switch second connecting rod 205 is provided with a shaft that is slidably connected to a groove on the switch buffer rod 206. Therefore, when the switch second connecting rod 205 rotates, the shaft of the switch second connecting rod 205 moves within the groove of the switch buffer rod 206. At the same time, the switch second connecting rod 205 drives the second end of the switch buffer rod 206 to rotate around the first end of the switch buffer rod 206 and pushes the switch buffer ring 209. The switch buffer ring 209 compresses the switch spring 208. After the second end of the switch buffer rod 206 is collinear with the switch second connecting rod 205 and continues to rotate, the switch spring 208 releases its elasticity and pushes the first end of the switch buffer rod 206. The switch drive rod 207 on the first end of the switch buffer rod 206 is slidably connected to the control rod housing 104. The first end of the switch buffer rod 206 rotates around the shaft of the switch second connecting rod 205, so that the first end of the switch buffer rod 206 moves downward, thereby driving the switch drive rod 207 to move downward. The switch second connecting rod 205 is connected to the switch second connecting rod 205 on the other side through the switch connecting rod 204 when rotating, thereby transmitting power.

[0030] The main knife switch assembly 3 further includes a main knife switch connecting shaft 309. The second end of the switch drive rod 207 is rotatably connected to the main knife switch connecting shaft 309. The first end of an upper push rod 308 is also rotatably connected to the main knife switch connecting shaft 309. The second end of the upper push rod 308 is rotatably connected to the first end of the main knife switch push rod 304. The second end of the main knife switch push rod 304 is fixedly connected to the main knife switch slide rod 303. The main knife switch push rod 304 is also slidably connected to the main knife switch lower slide rod 310. Springs are provided on the main knife switch lower slide rod 310 near the first ends of the two main knife switch push rods 304.

[0031] The described main knife switch assembly 3 further includes that the main knife switch upper sliding rod 305 is fixedly connected to the main body bracket 101, the main knife switch sliding rod 303 is slidably connected to the main knife switch upper sliding rod 305, the first end of the main knife switch limiting ring 306 is also slidably connected to the main knife switch upper sliding rod 305, the second end of the main knife switch limiting ring 306 is rotatably connected to the first end of the limiting plate 307, the limiting plate 307 is rotatably connected to the main body bracket 101, and a support plate is provided at the second end of the limiting plate 307.

[0032] As Figure 7 As shown, when the switch drive rod 207 moves downward, it will drive the main knife switch connecting shaft 309 to move downward. The main knife switch connecting shaft 309 pushes the main knife switch push rod 304 to move on the main knife switch lower sliding rod 310 through the upper push rod 308, and then drives the main knife switch sliding rod 303 to move on the main knife switch upper sliding rod 305. The main knife switch sliding rod 303 drives the main knife switch connecting frame 302 to slide on the rotating shaft 301. The spring on the main knife switch connecting frame 302 pulls the rotating shaft 301 to rotate, so as to realize the rotation of the rotating shaft 301 and the main knife switch connecting frame 302 around the axis of the rotating shaft 301. At the same time, the main knife switch connecting frame 302 rotates on the main knife switch sliding rod 303, and then drives the insulator 102 and the main knife switch 103 to rotate by ninety degrees through the rotating shaft 301, realizing the opening of the main knife switch 103. For closing, the reverse operation can be performed.

[0033] When the main knife switch sliding rod 303 moves to a position where it is about to rotate the rotating shaft 301 by ninety degrees, it will contact the main knife switch limiting ring 306, thereby pushing the main knife switch limiting ring 306 to move. The main knife switch limiting ring 306 drives the limiting plate 307 to rotate, so that the support plate at the second end of the limiting plate 307 moves away from the earthing knife switch sliding rod 501, releasing the restriction on the earthing knife switch sliding rod 501. A torsion spring is provided on the limiting plate 307 to facilitate resetting.

[0034] The transmission assembly 4 further includes a transmission side rod 401. The transmission side rod 401 is fixedly connected to the switch linkage rod 210. A transmission telescopic rod 402 is fixedly connected to the transmission side rod 401. A transmission side push-pull rod 403 is slidably connected to the transmission telescopic rod 402. A transmission sliding rod 407 is also slidably connected to the switch linkage rod 210. A spring is fixedly connected to the place on the switch linkage rod 210 where it contacts the transmission sliding rod 407. This spring is also fixedly connected to the transmission push block 408. The transmission push block 408 slides on the transmission sliding rod 407. The first end of a transmission lower push rod 409 is rotatably connected to the transmission push block 408. The second end of the transmission lower push rod 409 is rotatably connected to the first end of a transmission upper push rod 410. The second end of the transmission upper push rod 410 is fixedly connected to a transmission Z-shaped rod 412. The transmission Z-shaped rod 412 is slidably connected to the groove of the earthing knife switch sliding rod 501.

[0035] The transmission assembly 4 further includes a limit support plate 406. A transmission Z-shaped rod 412 is slidably connected to the limit support plate 406. The first end of a limit rod 404 is fixedly connected to the limit support plate 406. The second ends of the two limit rods 404 are fixedly connected by a connecting rod. The limit rod 404 is slidably connected to a limit bracket 405. The limit bracket 405 is fixedly connected to the main body bracket 101. A spring is provided between the limit support plate 406 and the limit bracket 405.

[0036] As Figure 8 and Figure 9 shown, when the switch linkage rod 210 starts to move upward for the first time, that is, when the control rod 201 is first pressed, the support plate of the limit plate 307 is still in contact with the grounding knife switch slide rod 501 and does not release the restriction on the grounding knife switch slide rod 501. The switch linkage rod 210 moves upward, compressing the spring between the switch linkage rod 210 and the transmission push block 408. At the same time, the transmission side rod 401 moves upward, pushing the transmission side push rod 403 upward. Eventually, it contacts the limit bracket 405. Then, due to the existence of the transmission telescopic rod 402, when the transmission side rod 401 continues to move upward, the transmission side push rod 403 slides on the transmission telescopic rod 402, and the transmission side push rod 403 will not push the limit bracket 405. After the grounding knife switch slide rod 501 is released from the restriction, the transmission push block 408 pushes the transmission upper push rod 410 to move through the transmission lower push rod 409. The transmission upper push rod 410 pushes the transmission Z-shaped rod 412 to slide on the transmission cross bracket 411. The transmission Z-shaped rod 412 will drive the grounding knife switch slide rod 501 to slide downward on the main body bracket 101. When the transmission Z-shaped rod 412 slides to the leftmost end, the limit support plate 406 no longer supports the transmission Z-shaped rod 412. The spring between the limit support plate 406 and the limit bracket 405 is in a compressed state in the initial state. Under the action of the spring, the limit support plate 406 moves upward. At the same time, the limit support plate 406 pulls the limit rod 404. Finally, the limit rod 404 contacts the transmission side push rod 403, thereby restricting the transmission Z-shaped rod 412 through the limit support plate 406 to prevent the transmission Z-shaped rod 412 from moving.

[0037] The grounding knife switch assembly 5 further includes a grounding knife switch pull rod 502. The shaft at the first end of the grounding knife switch pull rod 502 is rotatably connected to the grounding knife switch slide rod 501. The second end of the grounding knife switch pull rod 502 is rotatably connected to the first end of the grounding knife switch transmission rod 503. The second end of the grounding knife switch transmission rod 503 is rotatably connected to the shaft of the grounding knife switch ring rod 504. The second end of the grounding knife switch ring rod 504 is frictionally connected to the grounding knife switch 505. The first end of the grounding knife switch ring rod 504 pulls the grounding knife switch 505, and the second end of the grounding knife switch ring rod 504 pushes the grounding knife switch 505.

[0038] When the ground disconnecting switch sliding rod 501 moves downward, the ground disconnecting switch pull rod 502 is used to pull the ground disconnecting switch drive rod 503. The ground disconnecting switch drive rod 503 drives the ground disconnecting switch ring rod 504 to rotate on the main body bracket 101. When the ground disconnecting switch ring rod 504 rotates, it drives the ground disconnecting switch 505 to rotate. The upper end of the ground disconnecting switch 505 contacts the contact point of the main disconnecting switch 103, realizing the closing of the ground disconnecting switch 505. When reset is needed, just lift the control rod 201 upward, and the relevant structure will automatically reset. Finally, the ground disconnecting switch 505 will open first, and then the main disconnecting switch 103 will close.
