Description

Technical Field

[0001] The present invention relates to the technical field of disconnecting switches, and particularly to a closed type ice-melting disconnecting switch. Background Art

[0002] A disconnecting switch is a switching device mainly used for isolating power sources, performing switching operations, connecting and disconnecting small current circuits, and having no arc extinguishing function. When the disconnecting switch 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 can carry the current under normal circuit conditions and the current under abnormal conditions (such as short circuit) within a specified time. Generally used as a high-voltage disconnecting switch, that is, a disconnecting switch with a rated voltage above 1 kV, its working principle and structure are relatively simple. However, due to the large usage quantity and high requirements for working reliability, it has a great impact on the design, establishment, and safe operation of substations and power plants. The main feature of the disconnecting switch is its lack of arc extinguishing ability and can only connect and disconnect the circuit without load current. This entry introduces the functions, features, types, applications, anti-misoperation improvements, maintenance, common problems, etc. of the disconnecting switch.

[0003] Since the disconnecting switch is exposed to the environment, when encountering rain and snow in cold weather, icing will occur on the outer wall of the disconnecting switch. Especially, icing on the contact heads and isolating knife switches will cause the equipment to be unable to be normally switched on and off, thus interfering with the normal operation of the power grid system. At the same time, icing on the insulators will also reduce the insulation level, cause flashover grounding accidents, and even burn out the insulators, resulting in losses.

[0004] The existing ice-melting disconnecting switches have the following deficiencies:

[0005] Usually, a new set of high-voltage horizontally opening disconnecting switches is added between the ice-melting pipe bus and the high-voltage outgoing line. One end of this disconnecting switch is connected to the DC ice-melting bus, and the other end is connected to the high-voltage transmission line. Since the horizontally opening disconnecting switch equipment has a large external dimension, generally a relatively large area of site needs to be newly opened up, so the floor area increases and the investment is high.

[0006] It is impossible to perform a wrapped enclosure on the entire switch synchronously while closing, and the heat generated during ice melting is likely to be lost, reducing the ice-melting efficiency. Summary of the Invention

[0007] The purpose of the present invention is to provide a closed type ice-melting disconnecting switch.

[0008] To achieve this purpose, the present invention adopts the following technical solutions:

The motor is inserted into the mounting plate. The worm is fixedly arranged on its output end. The worm gear is fixedly arranged on one end of the first rotating shaft. The worm is meshed with the worm gear. The motor is electrically connected to the controller.

[0016] Further, each push-pull component includes a turntable, a connecting rod and two adapter blocks. The two adapter blocks are fixedly arranged on the inner wall of one of the sealing shells. Two L-shaped rods are symmetrically arranged on the top of the mounting block. The turntable is rotatably arranged on one of the L-shaped rods through a second rotating shaft. The connecting rod is hinged between the turntable and the two adapter blocks.

[0017] Further, the transmission assembly includes a first bevel gear, a second bevel gear, a first synchronous belt, and two first synchronous pulleys. A first hinge shaft is rotatably provided at the top of one L-shaped rod, and the two first synchronous pulleys are respectively fixed on the first rotating shaft and the first hinge shaft. The first synchronous belt is sleeved between the two first synchronous pulleys. The first bevel gear and the second bevel gear are respectively fixed on the first hinge shaft and the second rotating shaft, and the first bevel gear and the second bevel gear are meshed and connected.

[0018] Further, the conversion assembly includes a first gear, a second gear, a second synchronous belt, and two second synchronous pulleys.

[0020] Further, the induction assembly includes an induction rod and a proximity sensor.

The proximity sensor is electrically connected to the controller.

[0021] Further, semi-circular wiring holes are formed in the outer walls at both ends of each sealed shell.

[0022] Further, a plurality of V-shaped drainage grooves are symmetrically arranged on the outer wall of the bottom plate.

[0023] Advantages of the present invention:

[0024] By designing the controller, the switch body, the driving mechanism, and the ice melting mechanism, the present invention does not need to add a new set of high-voltage horizontally-opening disconnectors as in the prior art, and does not need to re-open a relatively large area of site, reducing the increase in floor area and at the same time reducing the investment, which is beneficial to saving the ice melting cost.

[0025] By designing the controller, the switch body, the driving mechanism, and the ice melting mechanism, when the isolating switch is closed, the two sealed shells can be driven to approach each other until they are butted and tightened, and the isolating switch body can be sealed in a wrapped state. By designing the induction assembly, automatic heating can be realized, and the heat generated during heating is not easily lost due to the sealed structure, thereby improving the ice melting effect.

[0026] The present invention designs a transmission component, which can drive two sealing shells to approach and tighten each other while the isolating switch is closed, and at the same time realizes automatic heating without manual intervention, improving the intelligence level of the switch. After closing, the conducted current will also generate a thermal effect, which can cooperate with several electric heating plates to quickly melt all the ice covering the isolating switch, improving the melting efficiency, ensuring the normal opening and closing of the equipment, thus ensuring the normal operation of the power grid system. At the same time, it prevents the insulator from icing and reducing the insulation level, causing flashover grounding accidents, or even burning out the insulator and causing losses.

[0027] The present invention designs a transmission component to realize the linkage operation of the driving mechanism and the ice melting mechanism. By only designing a motor, the synchronous operation of multiple mechanisms can be realized, reducing the overall power consumption of the switch, lowering the ice melting cost, while reducing the overall structure of the switch, decreasing the occupied space, and facilitating installation.

[0028] The present invention designs several V-shaped drainage grooves. When the ice covering the switch body melts into water after being heated, it drips from the outer wall of the switch body to the top of the bottom plate and is discharged from several V-shaped drainage grooves. The V-shaped drainage grooves have a structure that is wider at the top and narrower at the bottom. The wider top facilitates the outflow of the melted ice water, while the narrower bottom maximally prevents the loss of heat generated during heating, ensuring the ice melting effect.

[0029] The present invention designs four semi-circular wiring holes, which become two circular holes after the two sealing shells are docked in place. Thus, it is convenient for two wiring boards to be wired to other power equipment, and even after the two sealing shells are docked, the lines will not be damaged, improving the safety of ice melting and avoiding losses.

When ice melting work needs to be carried out, the motor 22 is started through the controller, so that its output end drives the worm 23 to rotate. Since the worm gear 24 is fixedly connected to one end of the first rotating shaft 13 and the worm 23 is meshed with the worm gear 24, and the isolating switch 19 and the ends of the two swing rods 14 away from the first rotating shaft 13 are respectively hinged to both ends of the insulating pull rod 18, and the isolating switch 19 is hinged to one of the wiring boards 20, the isolating switch 19 is driven to rotate towards the end close to the second contact head 17.

[0049] Referring to Figures 1 to 8As shown, each push-pull component includes a turntable 25, a connecting rod 26, and two adapter blocks 27. The two adapter blocks 27 are fixedly arranged on the inner wall of one of the sealing shells 15. Two L-shaped rods are symmetrically arranged at the top of the mounting block. The turntable 25 is rotatably arranged on one of the L-shaped rods through a second rotating shaft 28. The connecting rod 26 is hinged between the turntable 25 and the two adapter blocks 27. When the second rotating shaft 28 rotates clockwise, since both of the two adapter blocks 27 are fixedly connected to the inner wall of one of the sealing shells 15, the turntable 25 is fixedly connected to one of the L-shaped rods through the second rotating shaft 28, the top of the mounting block is fixedly connected to both of the two L-shaped rods, and the turntable 25 and the two adapter blocks 27 are respectively hinged to both ends of the connecting rod 26, thereby driving one of the sealing shells 15 to slide towards the end close to the disconnector.

[0050] Referring to Figures 1 to 8 As shown, the transmission component includes a first bevel gear 29, a second bevel gear 30, a first synchronous belt 31, and two first synchronous pulleys 32. A first hinge shaft is rotatably arranged at the top of one of the L-shaped rods. The two first synchronous pulleys 32 are respectively fixedly arranged on the first rotating shaft 13 and the first hinge shaft. The first synchronous belt 31 is sleeved between the two first synchronous pulleys 32. The first bevel gear 29 and the second bevel gear 30 are respectively fixedly arranged on the first hinge shaft and the second rotating shaft 28, and the first bevel gear 29 and the second bevel gear 30 are meshed and connected. While the first rotating shaft 13 rotates counterclockwise to drive the isolating switch 19 to rotate towards the end close to the second contact head 17, since the two first synchronous pulleys 32 are respectively fixedly connected to the first rotating shaft 13 and the first hinge shaft, the two first synchronous pulleys 32 are sleeved through the first synchronous belt 31, the first bevel gear 29 and the second bevel gear 30 are respectively fixedly connected to the first hinge shaft and the second rotating shaft 28, and the first bevel gear 29 and the second bevel gear 30 are meshed and connected, thereby driving the second rotating shaft 28 to rotate clockwise.

[0051] Referring to Figures 1 to 8As shown in the figure, the conversion component includes a first gear 33, a second gear 34, a second synchronous belt 35 and two second synchronous pulleys 36. The top of another L-shaped rod is rotatably provided with a second hinge shaft.

The two second synchronous pulleys 36 are respectively fixed on the second hinge shaft and one of the second rotating shafts 28. The second synchronous belt 35 is sleeved between the two second synchronous pulleys 36. When the second rotating shaft 28 rotates clockwise to drive one of the sealing shells 15 to slide towards the end close to the disconnector, since the two second synchronous pulleys 36 are respectively fixedly connected to the second hinge shaft and one of the second rotating shafts 28, the second synchronous belt 35 is sleeved between the two second synchronous pulleys 36, the second hinge shaft is rotatably connected to another L-shaped rod, the first gear 33 and the second gear 34 are respectively fixedly connected to the second hinge shaft and another second rotating shaft 28, and the first gear 33 and the second gear 34 are meshed and connected, so that the other turntable 25 rotates counterclockwise, and then drives the other sealing shell 15 to slide towards the mounting block through another connecting rod 26 and two adapter blocks 27, thereby making the two sealing shells 15 approach each other.

[0052] Refer to Figures 1 to 8 As shown in the figure, each heating component includes a plurality of electric heating plates 37. The plurality of electric heating plates 37 are fixedly arranged on the inner wall of one of the sealing shells 15. Each electric heating plate 37 is electrically connected to the controller. After the information that the two sealing shells 15 are butted and tightened is sent to the controller, the plurality of electric heating plates 37 are started by the controller. Since the plurality of electric heating plates 37 are respectively fixedly designed on the inner top and the inner side wall of the sealing shell 15, they cooperate with another heating component. After the two are butted and tightened, the switch body 12 located inside the two sealing shells 15 is heated in multiple directions, so that all the ice covering the outer wall of the switch body 12 is effectively heated, which is beneficial to improving the ice melting effect, ensuring the normal opening and closing of the equipment, thus ensuring the normal operation of the power grid system, and at the same time preventing the insulator from icing and reducing the insulation level, causing flashover grounding accidents, and even burning out the insulator, resulting in losses.

[0053] Refer to Figures 1 to 8 As shown in the figure, the induction component includes an induction rod 38 and a proximity sensor 39. The induction rod 38 and the proximity sensor 39 are respectively fixedly arranged on the outer walls of the two sealing shells 15. The axial directions of the induction rod 38 and the proximity sensor 39 are the same. The proximity sensor 39 is electrically connected to the controller. Since the induction rod 38 and the proximity sensor 39 are respectively fixedly designed at the adjacent ends of the two sealing shells 15 and the axial directions of the induction rod 38 and the proximity sensor 39 are the same, when the two sealing shells 15 approach each other until they are tightly attached, the proximity sensor 39 can detect the arrival of the induction rod 38 and send the information that the two sealing shells 15 are butted and tightened to the controller.

[0054] Referring to Figures 1 to 8 as shown, semi-circular wiring holes 40 are provided on the outer walls at both ends of each sealing shell 15. After the four semi-circular wiring holes 40 are butted in place for the two sealing shells 15, they become two circular holes, thus facilitating the wiring of the two wiring boards 20 with other electrical equipment. Even after the two sealing shells 15 are butted, the circuit will not be damaged, improving the safety of ice melting and avoiding losses.

[0055] Referring to Figures 1 to 8 as shown, a number of V-shaped drainage grooves 41 are symmetrically arranged on the outer wall of the bottom plate 11. When the ice covering the switch body 12 melts into water after being heated, it thus drips from the outer wall of the switch body 12 to the top of the bottom plate 11 and is discharged from the number of V-shaped drainage grooves 41. The V-shaped drainage grooves 41 have a structure that is wider at the top and narrower at the bottom. The wider top facilitates the outflow of the melted ice water, while the narrower bottom maximally prevents the loss of heat generated during heating, ensuring the ice melting effect.

[0056] The working principle of the present invention: When ice melting work needs to be carried out, the motor 22 is started through the controller, so that its output end drives the worm 23 to rotate. Since the worm gear 24 is fixedly connected to one end of the first rotating shaft 13, the worm 23 is meshed with the worm gear 24, and the isolating switch 19 and the two swing rods 14 are respectively hinged to both ends of the insulating pull rod 18 away from the first rotating shaft 13. The isolating switch 19 is hinged to one of the wiring boards 20, and then drives the isolating switch 19 to rotate towards the end close to the second contact head 17.

[0057] When the insulating pull rod 18 drives the isolating switch 19 to rotate towards the end close to the second contact head 17 until the end of the isolating switch 19 away from the first contact head 16 fits with the second plug, that is, when the isolating switch 19 rotates from an inclined state to a horizontal state, the first contact head 16, the second contact head 17, the isolating switch 19 and the two wiring boards 20 are sequentially connected to realize the conduction of current, and the heat effect of the current is used to achieve the effect of assisting ice melting, and at the same time prepare for the subsequent heating ice melting.

[0058] While the first rotating shaft 13 rotates counterclockwise to drive the isolating switch 19 to rotate towards the end close to the second contact head 17, since the two first synchronous wheels 32 are respectively fixedly connected to the first rotating shaft 13 and the first hinge shaft, the two first synchronous wheels 32 are sleeved by the first synchronous belt 31, and the first bevel gear 29 and the second bevel gear 30 are respectively fixedly connected to the first hinge shaft and the second rotating shaft 28, and the first bevel gear 29 and the second bevel gear 30 are meshed, thus driving the second rotating shaft 28 to rotate clockwise.

[0059] When the second rotating shaft 28 rotates clockwise, since both of the two adapter blocks 27 are fixedly connected to the inner wall of one of the sealing shells 15, the turntable 25 is fixedly connected to one of the L-shaped rods through the second rotating shaft 28, the top of the mounting block is fixedly connected to both of the L-shaped rods, and the turntable 25 and the two adapter blocks 27 are respectively hinged to both ends of the connecting rod 26, thereby driving one of the sealing shells 15 to slide towards the end close to the disconnecting switch.

[0060] When the second rotating shaft 28 rotates clockwise to drive one of the sealing shells 15 to slide towards the end close to the disconnecting switch, since the two second synchronous pulleys 36 are respectively fixedly connected to the second hinge shaft and one of the second rotating shafts 28, the second synchronous belt 35 is sleeved between the two second synchronous pulleys 36, the second hinge shaft is rotatably connected to the other L-shaped rod, the first gear 33 and the second gear 34 are respectively fixedly connected to the second hinge shaft and the other second rotating shaft 28, and the first gear 33 and the second gear 34 are meshed and connected, thereby causing the other turntable 25 to rotate counterclockwise, and thus driving the other sealing shell 15 to slide towards the mounting block through the other connecting rod 26 and the two adapter blocks 27, so that the two sealing shells 15 approach each other.

[0061] Since the induction rod 38 and the proximity sensor 39 are respectively fixedly designed at adjacent ends of the two sealing shells 15, and the axial directions of the induction rod 38 and the proximity sensor 39 are the same, when the two sealing shells 15 approach each other until they are tightly attached, the proximity sensor 39 can detect the arrival of the induction rod 38 and send the information of the two sealing shells 15 being butted and tightened to the controller.

[0062] After the information that the two sealing shells 15 are butted and tightened is sent to the controller, a plurality of electric heating plates 37 are started through the controller. Since the plurality of electric heating plates 37 are respectively fixedly designed on the inner top and the inner side wall of the sealing shell 15, thus cooperating with the other heating assembly, after the two are butted and tightened, the switch body 12 located inside the two sealing shells 15 is heated in multiple directions, so that all the ice covering the outer wall of the switch body 12 is effectively heated, which is beneficial to improving the ice melting effect, ensuring the normal opening and closing of the equipment, thus ensuring the normal operation of the power grid system, and at the same time preventing the insulator from icing and reducing the insulation level, causing flashover grounding accidents, or even burning out the insulator and causing losses.

[0063] When the ice covering the switch body 12 melts into water after being heated, it thus drips onto the top of the bottom plate 11 from the outer wall of the switch body 12 and is discharged from a plurality of V-shaped drainage grooves 41. The V-shaped drainage grooves 41 have a structure that is wider at the top and narrower at the bottom. The wider top is convenient for the melted ice water to flow out, while the narrower bottom is to prevent the heat generated during heating from being lost to the greatest extent and ensure the ice melting effect.

[0064] After the two sealing shells 15 are butted in place, the four semi-circular wiring holes 40 become two circular holes, thus facilitating the wiring of the two wiring boards 20 to other electrical equipment. Even after the two sealing shells 15 are butted, the circuit will not be damaged, improving the safety of ice melting and avoiding losses.
