Description

Technical Field

[0001] This invention relates to the field of high-voltage disconnector lubrication technology, specifically a safe and reliable live lubrication device for high-voltage disconnectors. Background Technology

[0002] High-voltage disconnect switches are crucial switching equipment in substation electrical systems. Their primary function is to reliably isolate the energized parts of a high-voltage power distribution system from the energized parts, ensuring safety during maintenance. A typical high-voltage disconnect switch comprises a conductive blade, stationary contact, intermediate transmission components, and a mechanism housing. These components are connected sequentially. A lubrication system is required within the high-voltage disconnect switch for routine maintenance to prevent blockages in the connections.

[0003] As the closest prior art, Chinese Patent Publication No. CN102691870A discloses a high-voltage disconnector energized lubrication device, including a high-voltage insulating rod and a controller. The end of the high-voltage insulating rod is equipped with a lubricator and a camera. The camera is a flexible hose camera, and the lubricator is equipped with a lubrication pipe.

[0004] Currently, the live lubrication devices for high-voltage disconnect switches and the structures mentioned above are mostly lubricated manually. However, in actual use, mechanized operation is often required to automate the lubrication process. This would reduce manpower consumption and ensure safety. Therefore, an improved device is needed to address these issues. Summary of the Invention

[0005] To address the problems in the prior art, this invention provides a safe and reliable live lubrication device for high-voltage disconnect switches, which can lubricate critical connection parts, enabling the equipment to be used for a long time.

[0006] The technical solution adopted by the present invention to solve its technical problem is: a safe and reliable high-voltage disconnector live lubrication device, including a lubrication switch structure, a support column and a support insulation frame, wherein the upper end of the support column is fixedly connected to the support insulation frame, and the upper end of the support insulation frame is limited and installed with the lubrication switch structure;

[0007] The lubrication switch structure includes a lubrication component and a switch component. The rear end of the lubrication component is connected to the switch component, and the rear end of the switch component is connected to the symmetrical lubrication component.

[0008] The lubrication system includes a connecting pipe, a flow pipe, a mating connecting pipe, a guide processing pipe, an oil pump, a connecting seat, an oil reservoir, a central conduit, a mating installation pipe, a maintenance oil injection pipe, and a connecting pipe. Oil flows from the oil reservoir into the connecting seat, where it is pressurized by the oil pump and transported through the guide processing pipe to the flow pipe. It then connects with the bearing housing and circulates through the connecting pipe to the mating connecting pipe, reaching the oil reservoir. Simultaneously, the connecting seat introduces oil through the central conduit, which is then conducted to the mating installation pipe and the connecting pipe, acting on the bearing housing at the center for lubrication of the switching components. The lower end of the oil reservoir is connected to the connecting seat. An oil pump is mounted on the side of the connecting seat. A guide processing pipe is located near the oil pump on the connecting seat. The rear end of the guide processing pipe is fixedly connected to the flow pipe. The rear side of the oil reservoir is fixedly connected to the mating connecting pipe, which is fixedly connected to... The connecting pipe has a maintenance oil injection pipe at its center. A central conduit is fixedly connected to the connecting pipe near the maintenance oil injection pipe. The upper end of the central conduit is connected to the mating installation pipe, and the rear end of the mating installation pipe is connected to the connecting pipe. The structure of the lubrication components facilitates lubrication and enables automated lubrication control. The maintenance oil injection pipe facilitates oil injection, and the oil is stored inside the oil reservoir. The connecting pipe and the oil reservoir are connected. The oil is pressurized and transmitted by the control of the oil pump, reaching the interior of the guide pipe. Then, it enters the bearing seats at the lower ends of the first and second rotating disks through the flow pipe, achieving the purpose of oil supply and lubrication. At the same time, the oil can be transmitted through the central conduit to the connecting pipe, reaching the bearing seat at the lower end of the first rotating disk at the center, and can also flow back into the interior of the connecting pipe, thereby achieving automated oil supply and reducing manual intervention.

[0009] Specifically, the switch component includes a swing rod, a first rotating disk, a limiting mounting bracket, a support base, a second rotating disk, an insulator, a moving contact, a magnetic block, and a stationary contact. The upper end of the support base is fixedly connected to the limiting mounting bracket, and the upper end of the limiting mounting bracket is rotatably connected to the first rotating disk. A second rotating disk is located symmetrically to the first rotating disk, and an insulator is located on the upper end of the second rotating disk. A moving contact is limited and mounted on the upper end of the insulator. A motor drives a drive rod to rotate, and a control guide rod is hinged to the upper end of the drive rod, enabling the control guide rod to follow the movement. The upper end is connected to the docking swing adjustment rod via the central guide rod frame, which can drive the docking swing adjustment rod to perform tension adjustment. The docking swing adjustment rod can drive the first rotating disk to rotate. The lower end of the first rotating disk is equipped with a bearing seat, which allows the upper structure to rotate as a whole. When the first rotating disk rotates, it can drive the swing rod to swing and adjust. The swing of the swing rod can drive the second rotating disk to follow and adjust, thereby adjusting the moving contact and the stationary contact. When the moving contact and the stationary contact rotate and contact, the magnetic block is attracted, so that the moving contact and the stationary contact are docked and closed for energization.

[0010] Specifically, the upper end of the first rotating disk is provided with symmetrical insulators, and stationary contacts are provided on the symmetrically arranged insulators. A magnetic block is installed at the upper limit of the stationary contact.

[0011] Specifically, the bottom of both the first and second rotating disks is provided with bearing seats, and the side ends of both the first and second rotating disks are hinged with swing rods, and the two swing rods are hinged together by a connecting rod.

[0012] Specifically, the switch component further includes a drive rod, a control guide rod, a limit pole frame, a docking swing adjustment rod, a central guide rod frame, and a motor. The upper end of the motor is connected to the drive rod, the upper end of the drive rod is hinged to the control guide rod, the upper end of the control guide rod is hinged to the central guide rod frame, and the upper end of the central guide rod frame is hinged to the docking swing adjustment rod. Through the structural arrangement of the switch component, switch control can be performed. The motor is the driving component, which drives the drive rod to rotate. The drive rod causes the control guide rod, the central guide rod frame, and the docking swing adjustment rod to rotate accordingly, thereby pulling the first rotating disk to rotate on the bearing seat, changing the position of the swing rod. The swing rod can drive the symmetrical second rotating disk to rotate and adjust, thereby enabling the moving contact and stationary contact to separate and close, achieving the purpose of switch adjustment.

[0013] Specifically, a limiting pole frame is provided at the longitudinal position of the control guide rod, and the limiting pole frame is fixedly connected to the center of the limiting mounting frame.

[0014] Specifically, the side end of the docking swing adjustment rod is hinged to the first rotating disk. The docking swing adjustment rod drives the first rotating disk to rotate, and the first rotating disk drives the second rotating disk to follow the movement through the swing rod and connecting rod.

[0015] Specifically, the moving contact and the stationary contact are magnetically attracted to each other via magnetic blocks.

[0016] Specifically, the connecting pipe and the flow pipe are fixedly connected to the bearing seat at the lower end of the first rotating disk. There are three first rotating disks and three second rotating disks. The connecting pipe is connected to the first rotating disk at the center position.

[0017] Specifically, a liquid level monitor is installed on one side of the connecting seat, and a signal transmitter is installed on the other side of the connecting seat.

[0018] The beneficial effects of this invention are:

[0019] First, this invention facilitates lubrication through the structural design of the lubrication components, enabling automated lubrication control. The maintenance oil injection pipe facilitates oil injection, with oil stored inside the oil reservoir. The reservoir and the connecting seat are connected. The oil is pressurized and transmitted via an oil pump, reaching the guide pipe and then flowing through the circulation pipe to the bearing seats at the lower ends of the first and second rotating disks, achieving lubrication. Simultaneously, the oil can be conducted through the central conduit to the connecting pipe location, reaching the bearing seat at the lower end of the first rotating disk at the center, and then flowing back to the connecting seat, thus achieving automated oil supply and reducing manual intervention. Through the conduction of lubricating oil, the switch positions are lubricated, allowing for long-term equipment operation and preventing damage and aging. During installation and use, a safe distance should be maintained, with the height above the ground controlled at over 3 meters, and an insulation safety distance of over 1 meter for lateral clearance. An internal insulating rod is also installed for insulation protection, preventing high-voltage breakdown.

[0020] Second, the present invention enables switch control through the structural design of the switch components. The motor is the driving component, which drives the drive rod to rotate. The drive rod causes the control guide rod, the central guide rod frame, and the docking swing adjustment rod to rotate accordingly, thereby pulling the first rotating disk to rotate on the bearing seat, changing the position of the swing rod. The swing rod can drive the symmetrical second rotating disk to rotate and adjust, thereby enabling the moving contact and stationary contact to separate and close, achieving the purpose of switch adjustment.

The upper end of the central conduit 13 is connected to the mating mounting pipe 14, and the rear end of the mating mounting pipe 14 is connected to the connecting pipe 16. The oil flows through the oil reservoir 12 to the connecting seat 11. Under the pressure of the oil pump 10, the oil is transferred and can be conducted through the guide processing pipe 9 to the flow pipe 7. Then it connects with the bearing seat and can circulate through the connecting pipe 6 to the mating connecting pipe 8, reaching the oil reservoir 12. At the same time, the connecting seat 11 can introduce oil through the central conduit 13, which is conducted to the mating mounting pipe 14 and the connecting pipe 16, acting on the bearing seat at the center position to lubricate the switching component 5.

[0038] like Figure 6 As shown, the switch component 5 includes a swing arm 17, a first rotating disk 18, a limiting mounting bracket 19, a support base 20, a second rotating disk 21, an insulator 22, a moving contact 23, a magnetic block 24, and a stationary contact 25.

[0040] The bottom of the first rotating disk 18 and the second rotating disk 21 are both provided with bearing seats, and the side ends of the first rotating disk 18 and the second rotating disk 21 are both hinged with swing rods 17, and the two swing rods 17 are hinged together by a connecting rod.

[0041] like Figure 7As shown, the switch component 5 also includes a drive rod 26, a control guide rod 27, a limit pole frame 28, a docking swing adjustment rod 29, a central guide rod frame 30, and a motor 31.

The upper end of the control guide rod 27 is hinged to the central guide rod frame 30, and the upper end of the central guide rod frame 30 is hinged to the docking swing adjustment rod 29. When the motor 31 operates, it drives the drive rod 26 to rotate. The upper end of the drive rod 26 is hinged to the control guide rod 27, which can drive the control guide rod 27 to follow the movement. The upper end of the control guide rod 27 is connected to the central guide rod frame 30. The docking swing adjustment rod 29 is connected to the docking swing adjustment rod 29, which can be driven to stretch and adjust. The docking swing adjustment rod 29 can drive the first rotating disk 18 to rotate. The lower end of the first rotating disk 18 is provided with a bearing seat, which can make the upper structure rotate as a whole. When the first rotating disk 18 rotates, it can drive the swing rod 17 to swing and adjust. The swing of the swing rod 17 can drive the second rotating disk 21 to follow and adjust, thereby adjusting the moving contact 23 and the stationary contact 25. When the moving contact 23 and the stationary contact 25 rotate and contact, the magnetic block 24 is attracted, so that the moving contact 23 and the stationary contact 25 are docked and closed for energization.

[0042] A limiting pole frame 28 is provided at the longitudinal position of the control guide rod 27, and the limiting pole frame 28 is fixedly connected to the center of the limiting mounting frame 19.

[0043] The side end of the docking swing adjustment rod 29 is hinged to the first rotating disk 18. The docking swing adjustment rod 29 drives the first rotating disk 18 to rotate, and the first rotating disk 18 drives the second rotating disk 21 to follow the movement through the swing rod 17 and the connecting rod.

[0044] The moving contact 23 and the stationary contact 25 are magnetically attracted to each other by magnetic block 24.

[0045] The connecting pipe 6 and the flow pipe 7 are fixedly connected to the bearing seat at the lower end of the first rotating disk 18. There are three first rotating disks 18 and second rotating disks 21. The connecting pipe 16 is connected to the first rotating disk 18 at the center position.

[0046] The working principle of this embodiment is as follows: During use, the user installs the lubrication switch structure 1, support column 2, and support insulation frame 3 as a whole. The support column 2 and support insulation frame 3 are fixed to support the lubrication switch structure 1. The lubrication switch structure 1 plays the role of switching adjustment. The lubrication switch structure 1 is composed of lubrication components 4 and switch components 5. The lubrication components 4 are symmetrically arranged about the switch components 5. The two lubrication components 4 can provide oil to the switch components 5 for lubrication. The moving contact 23 and stationary contact 25 in the switch components 5 are connected to the external circuit. When closure is required, the motor 31 works, driving the drive. The rod 26 rotates, and a control guide rod 27 is hinged to the upper end of the drive rod 26, which can drive the control guide rod 27 to follow the movement. The upper end of the control guide rod 27 is connected to the docking swing adjustment rod 29 through the central guide rod frame 30, which can drive the docking swing adjustment rod 29 to perform tension adjustment. The docking swing adjustment rod 29 can drive the first rotating disk 18 to rotate. The lower end of the first rotating disk 18 is provided with a bearing seat, which can make the upper structure rotate as a whole. When the first rotating disk 18 rotates, it can drive the swing rod 17 to swing and adjust. The swing of the swing rod 17 can drive the second rotating disk 21 to follow the adjustment, thereby adjusting the moving contact 23 and the stationary contact 25. When the moving contact 23 and the stationary contact 25 are adjusted, the second rotating disk 21 will also be adjusted. When contact 25 rotates and contacts, the magnetic block 24 attracts it, causing the moving contact 23 and the stationary contact 25 to engage and close for energization. When de-energization is required, the drive rod 26 reverses its direction, simultaneously rotating the first rotating disk 18 and the swing rod 17, thereby separating the moving contact 23 and the stationary contact 25 to achieve circuit breaking. During operation, lubrication adjustment is performed. Oil flows through the oil reservoir 12 to the connecting seat 11, where it is pressurized by the oil pump 10 and transmitted through the guide pipe 9 to the flow pipe 7. It then connects with the bearing seat and circulates through the connecting pipe 6 to the mating connecting pipe 8. The oil reaches the oil reservoir 12, and the connecting seat 11 can introduce oil through the central conduit 13, which is then conducted to the mating installation pipe 14 and the connecting pipe 16. The oil acts on the bearing seat at the center position to lubricate the switch component 5. Through the conduction of the lubricating oil, the switch position can be lubricated, thus enabling the equipment to operate for a long time and preventing equipment damage and aging. At the same time, when installing and using the equipment, the safety distance should be controlled, with the height from the ground controlled at more than 3m, and the insulation safety distance should be controlled, with the lateral clearance of the equipment controlled at more than 1m, so as to ensure the safety distance of the equipment. An internal insulating rod is installed for insulation protection to prevent high voltage breakdown of the equipment.

[0047] Example 2

[0048] Based on Example 1, such as Figure 8 As shown, a liquid level monitor 32 is installed on one side of the connecting seat 11, and a signal transmitter 33 is installed on the other side of the connecting seat 11.

[0049] In this embodiment, the level monitor 32 monitors the level of the oil in the connecting seat 11, which facilitates the detection of the amount of oil inside. The signal transmitter 33 is set up to transmit signals, which can be conveniently transmitted to the outside oil level for better maintenance.
