Description

Technical Field

[0001] This invention relates to a novel integrated insulator capable of live-line operation and its installation method, belonging to the field of insulator technology. Background Technology

[0002] Currently, most post insulators used in 10kV overhead lines in China are fixed using binding wires. However, as users demand higher power supply reliability, the need for live-line work and routine maintenance is increasing. Yet, existing insulator types present difficulties for live-line installation. In daily distribution network maintenance, the disadvantages of traditional insulators are mainly manifested in the following aspects.

[0003] (1) Live-line installation is difficult because traditional insulators are mostly fixed by binding wires, which are mostly found in rural power grids. The operation is carried out by using insulated gloves. Because the binding wires need to be wrapped repeatedly, the operation time is long. The binding wires can only be temporarily fixed by using insulated rods (the power needs to be cut off later for permanent binding). Because the wrapping method is complicated, the existing robot operation cannot be used to install it. (2) The binding wire is wrapped around the conductor in multiple turns, which is time-consuming and laborious in the installation process. In addition, the binding wire will generate induced current inside, causing the binding wire to heat up and damage the insulation layer of the power conductor. (3) If the binding is not tight, the conductor will be subjected to external forces such as wind load for a long time, which will cause the binding wire to loosen easily, or even break and wear on the conductor insulation layer. When it reaches a certain extent, the conductor insulation layer will have gaps. In addition, loose or loose binding can also easily cause the insulator to shift or break, causing the overhead conductor to fall on the crossarm or hang in the air, affecting the reliability of the safe operation of the power distribution equipment, and even endangering the lives of personnel. (4) The lightning protection level of lightning protection insulators varies. The installation of different types of lightning protection insulators makes the pole head complicated. Many types of products have not passed effective testing. Traditional lightning protection insulators have no fault indication. If a fault occurs, the conductor may fall off. (5) Under normal circumstances, faults are prone to occur at the individual connection points of the surge arrester; (6) The construction process involves carrying too many tools and the binding process is complicated, time-consuming and labor-intensive. Summary of the Invention

[0004] The purpose of this invention is to provide a novel integrated insulator capable of live-line work and its installation method. This allows for live-line work operations to be performed manually or using a live-line work robot, saving time and effort, improving work efficiency, ensuring secure binding, preventing insulator displacement or breakage that could cause safety hazards, and providing excellent wind and lightning protection. This addresses the aforementioned problems in the prior art.

[0005] The technical solution of this invention is: A novel integrated insulator for live-line operation comprises a cover, a spring, an operating screw, a lower base, a driven block, a threaded block, and an insulator body. The lower base is located on the top of the insulator body, with a lower groove at one end and a threaded block at the other end. The cover is hinged to the lower base in the middle, with an upper groove at one end. The upper and lower grooves correspond to form a conductor clamping groove. The driven block is located at the other end of the cover. The lower part of the operating screw is threaded to the threaded block and has an operating ring at the bottom. The upper part of the operating screw is movably connected to the driven block. A spring is located on the operating screw between the lower base and the cover. The outer surfaces of the upper groove of the cover and the lower groove of the lower base are covered with buffer pads.

[0006] Furthermore, the upper part of the operating screw is movably connected to the through hole of the driven block via a cotter pin, allowing the operating screw to rotate freely; the other end of the lower base is connected to the threaded block via a second elastic pin.

[0007] Furthermore, the upper end face of the lower base is provided with a hinge seat, and the cover includes two symmetrically arranged swing arms. One end of the two swing arms is connected to the driven block by a three-elastic pin, and the other end of the two swing arms is connected as a whole in an arc shape and covered with a buffer pad. The middle part of the two swing arms is hinged to the hinge seat by a one-elastic pin.

[0008] Furthermore, the insulator body has multiple layers of skirts arranged from top to bottom on the umbrella sleeve, with the outer diameter of the uppermost and lowermost skirts being larger than the outer diameter of the skirts in between.

[0009] Furthermore, the insulator body includes an upper fitting, a lower fitting, a sheath, skirts, and a central assembly. The sheath covers the outside of the central assembly, and multiple skirts are provided outside the sheath. The central assembly includes a core and multiple annular resistance sheets fitted on the core. The upper and lower ends of the core are respectively located in the upper and lower fittings, and corrugated pads are provided between adjacent layers of resistance sheets. The multiple annular resistance sheets form a columnar assembly, and the outside of the columnar assembly is connected to an insulating tube through potting compound.

[0010] Furthermore, the central component also includes a butterfly spring, an upper clamping seat, a current inlet seat, and a current outlet seat disposed on the core. The current inlet seat and the current outlet seat are respectively disposed at the upper and lower ends of the columnar component. The current inlet seat and the upper clamping seat are threaded together. The upper clamping seat is pressed against the uppermost resistor sheet by an upper washer and an upper corrugated pad. A butterfly spring is disposed between the current outlet seat and the lowermost resistor sheet. A lower washer and a lower corrugated pad are disposed between the upper end of the butterfly spring and the lowermost resistor sheet. A lower corrugated pad is disposed between the lower end of the butterfly spring and the current outlet seat.

[0011] Furthermore, O-rings are provided at the connection points between the current inlet seat and the current outlet seat and the upper and lower ends of the insulating tube.

[0012] Furthermore, the top of the upper hardware is a lower base, and an upper guide rod is provided on one side of the lower base. The outer side of the upper guide rod is also covered with a buffer pad, and it is integrated with the buffer pad in the lower groove of the lower base. The current inlet seat is equipped with a lower guide rod through a flat-end set screw.

[0013] Furthermore, the lower fitting is equipped with a steel foot, and the bottom of the insulator body is equipped with a disconnector, which is connected to the steel foot via a metal stranded wire. The disconnector, as a special accessory for surge arresters, is a well-known product in the field. Used in series with the surge arrester, it can quickly activate when the surge arrester malfunctions, throwing the faulty arrester out of the power grid and providing a clear disconnection indication, making it easier for maintenance personnel to locate the fault and replace the surge arrester.

[0014] Furthermore, the umbrella skirt is flat, and the upper and lower fittings are provided with clamping guide grooves to ensure that the end effector of the live-line working robot is stable and does not slip during clamping and transportation.

[0015] Based on the above-mentioned installation method of the new integrated insulator for live-line work, when the insulator needs to be installed, the operator connects the top of the insulating rod to the operating ring of the operating screw, or connects the end effector of the live-line work robot to the operating ring. By rotating, the operating screw is driven to rotate. Since the operating screw is threadedly connected to the threaded block, the operating screw moves downward while rotating, causing the end of the pressure cover with the upper groove to lift up and place the wire into the lower groove. Rotating in the opposite direction causes the operating screw to rotate, and the operating screw moves upward, causing the end of the pressure cover with the upper groove to fall down and fix the wire in the wire clamping groove.

[0016] The advantages of this invention are: 1. The pressure cap, pressure spring, operating screw, lower base, driven block and threaded block constitute the adjustable wire fixing assembly. The adjustable wire fixing assembly is set at the top of the insulator body and can reliably support the conductor. It subverts the traditional method of using plastic copper wire to wrap and bind, and the wire fixing method is standardized. It will not cause the conductor to loosen or suffer serious wear due to the technical problems of binding.

[0017] 2. The use of a combination of operating screw and compression spring ensures that the product will not loosen and cause the wire to move back and forth or be severely worn, even under strong vibrations caused by strong winds. It has strong windproof and wire-fixing capabilities.

[0018] 3. It greatly improves the reliability of live-line work operations, facilitates the operation of live-line work robots and insulating rods, and the simple rotation action solves the bottleneck problems that robots cannot replace traditional wire-binding insulators and that insulating rods can only temporarily fix the wires. It realizes "machine replacing man" and "long-distance" live-line work, and improves the safety and convenience of the operation.

[0019] 4. It avoids the problem of induced current heating damaging the wire insulation layer due to multiple turns of the wire.

[0020] 5. The operating screw can be used with various types of operating rods for live operation, enhancing safety.

[0021] 6. The adjustable wire fixing assembly, surge arrester, and insulator are integrated into one unit, eliminating the need to carry binding wires or install surge arresters during construction. Maintenance and replacement do not require carrying large rolls of binding wire, avoiding the safety issues of phase-to-phase short circuits that may occur during the binding process.

[0022] 7. The adjustable pressure cap type wire fixing structure is easy to operate and solves the problem of complicated, time-consuming and labor-intensive wire binding process during construction.

[0023] 8. Excellent wind and lightning protection performance. This product integrates the functions of a gap surge arrester, adopts an integrated design to reduce the number of connection points on overhead lines; it also has a lightning fault indication function and a surge arrester anti-drop-off structure, making operation and maintenance convenient.

[0024] The positive effects of this invention are: it allows for live-line work operations to be performed manually or using a live-line working robot, providing long-term support and fixation for the conductors. The operation is simple, time-saving, and labor-saving, increasing operational safety and solving the problem of induced current heating damaging the conductor insulation layer. It also has good wind and lightning protection performance. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments: See attached document Figure 1 and 2 Embodiment 1 provides a windproof insulator for live-line operation, comprising a cover 1, a spring 2, an operating screw 3, a lower base 4, a driven block 5, a threaded block 6, and an insulator body 17. The top of the insulator body 17 is provided with a lower base 4, one end of which is provided with a lower groove 9, and the other end of which is provided with a threaded block 6 via an elastic pin 2 13. The middle part of the cover 1 is hinged to the lower base 4, and one end of the cover 1 is provided with an upper groove 10. The upper groove 10 and the lower groove 9 correspond to each other to form a conductor clamping groove. The other end of the cover 1 is provided with a driven block 5. The lower part of the operating screw 3 is threadedly connected to the threaded block 6 and has an operating ring 8 at the bottom. The operating screw 3 is inclined, and the upper part of the operating screw 3 is movably connected to the driven block 5 via a cotter pin 11. The operating screw 3 can rotate freely. A spring 2 is provided on the operating screw 3 between the lower base 4 and the cover 1. The outer surfaces of the upper groove 10 of the cover 1 and the lower groove 9 of the lower base 4 are covered with a buffer pad 7.

[0027] The pressure cap 1 and the lower base 4 are made of aluminum alloy and have an open-loop structure, which makes it difficult to generate induced current inside and avoid heat loss. The contact parts between the pressure cap 1 and the lower base 4 and the wire are all covered with buffer pads 7, such as high-performance silicone rubber layers, which not only provide sufficient anti-slip friction, but also prevent the wire insulation layer from being worn due to vibration caused by wind, thus achieving "firm but not damaged".

[0028] The upper end face of the lower base 4 is provided with a hinge seat 20. The pressure cover 1 includes two symmetrically arranged swing arms 1-1. One end of the two swing arms 1-1 is connected to the driven block 5 through an elastic pin 3 19. The other end of the two swing arms 1-1 is connected as a whole in an arc shape and covered with a buffer pad 7. The middle part of the two swing arms 1-1 is hinged to the hinge seat 20 through an elastic pin 12.

[0029] This invention employs a lever-type clamping structure and a spring damping system. This structure achieves rapid wire fixation by changing the direction of the force, eliminating the need for winding and binding wires, thus improving installation efficiency by more than 50%. Tests have verified that this structure can withstand a horizontal force of 6kN perpendicular to the wire and can withstand wind loads generated by wind speeds of 55m / s (approximately a Category 16 typhoon) (Note: 6kN force is 2.5 times the theoretical value of the force exerted on the wire by a typhoon at 55m / s). Under these conditions, it maintains wire stability and does not loosen, demonstrating excellent wind resistance.

[0030] In this embodiment, the opening size of the pressure cap 1 is adjusted by a live operating rod (insulating rod). The opening adjustment range of the pressure cap 1 is 35mm, which can reliably fix various specifications of conductors from 50mm² to 240mm², meeting the complex requirements of power distribution network conductor models. During the tightening operation, the operating screw 3 applies a certain elastic force to the pressure cap 1, which can prevent the operating screw 3 from loosening due to conductor vibration, thus preventing the conductor insulation layer from wearing and the high-voltage conductor from being exposed.

[0031] The lever-type clamping structure, combined with a threaded self-locking anti-loosening structure, secures overhead conductors. The structure is stable, with multiple anti-loosening measures ensuring consistent performance and avoiding inconsistent binding methods. After use, it guarantees the secure and stable installation of related power conductors, preventing loosening. The clamping cap 1 is driven by a rotating operating screw 3. The lower end of the operating screw 3 features a universal operating ring 8, allowing for quick, stable, and non-destructive docking and force transmission with various insulating rods and the end effectors of live-line working robots, overcoming the bottleneck of robots being unable to replace linear insulators. This transforms differentiated binding processes into standardized "rotational" mechanical actions, solving the problem of only temporarily fixing the binding wire when replacing linear insulators with insulating rods. It achieves one-time permanent wire fixing when replacing linear insulators with insulating rods, simplifying the work process and enabling rapid disassembly.

[0032] In this embodiment, the insulator body 17 has one umbrella sleeve 17-3. The umbrella sleeve 17-3 is provided with multiple layers of umbrella skirts arranged from top to bottom. The outer diameter of the uppermost umbrella skirt 17-4 and the lowermost umbrella skirt 17-5 is larger than the outer diameter of the umbrella skirts between them.

[0033] The umbrella skirt structure in this implementation adopts a combination of large and small umbrella skirts. The top uses an extra-large umbrella skirt, which can not only block dust and foreign objects, but also protect the lower umbrella skirt from the effects of moisture freezing, giving the insulator anti-icing capability. The material is high-quality anti-fouling rubber, and the anti-fouling capability can reach level e.

[0034] This invention allows the use of a live-line working rod to lift the insulator and place it in a suitable hole in the angle steel. Then, the live-line working rod is used to tighten the nut at the steel foot, securing it to the angle steel, thus fixing the live-line working rod in place.

[0035] See attached document Figure 3-7 See attached Figure 6 and 7 Unlike the windproof insulator for live-line work, the insulator in Embodiment 2 adds lightning protection, making it an integrated windproof and lightning protection insulator for live-line work. In addition to the same components as described in Embodiment 1, it also has a central assembly. This central assembly includes a core 17-6 and multiple annular resistance sheets 17-7 fitted onto the core 17-6. The upper and lower ends of the core 17-6 are respectively located within upper fitting 17-1 and lower fitting 17-2. Corrugated pads 17-8 are provided between adjacent layers of resistance sheets 17-7. The multiple annular resistance sheets 17-7 form a columnar assembly, and the outer side of the columnar assembly is connected to an insulating tube 17-10 via potting compound 17-9.

[0036] See attached document Figure 7 The central assembly further includes a butterfly spring 17-11, an upper clamping seat 17-12, a current inlet seat 17-13, and a current outlet seat 17-14 disposed on the core 17-6. The current inlet seat 17-13 and the current outlet seat 17-14 are respectively disposed at the upper and lower ends of the columnar assembly. The current inlet seat 17-13 and the upper clamping seat 17-12 are threadedly connected. The upper clamping seat 17-12 is connected to the upper wave via an upper washer 17-15. A corrugated pad 17-16 is pressed tightly onto the uppermost resistor piece 17-7. A butterfly spring 17-11 is provided between the current lead-out seat 17-14 and the lowermost resistor piece 17-7. A lower washer 17-17 and a lower corrugated pad 17-18 are provided between the upper end of the butterfly spring 17-11 and the lowermost resistor piece 17-7. A lower corrugated pad 17-19 is provided between the lower end of the butterfly spring 17-11 and the current lead-out seat 17-14. O-rings 17-20 are provided at the connection points between the current lead-in seat 17-13 and the current lead-out seat 17-14 and the upper and lower ends of the insulating tube 17-10.

[0037] See attached document Figure 5The top of the upper hardware 17-1 is the lower base 4. The lower base 4 has an upper drain rod 16 on one side. The upper drain rod 16 is also covered with a buffer pad 7 on the outside and is integrated with the buffer pad 7 in the lower groove 9 of the lower base 4. The current inlet seat 17-13 is equipped with a lower drain rod 18 by a flat-end set screw 17-22.

[0038] See attached document Figure 4 The lower end fitting 17-2 is provided with a steel foot 17-21. The detachment part of the detachment device 14 is connected to the steel foot 17-21 through a metal stranded wire 15. The bottom of the core 17-6 is provided with a connecting screw 17-24 through a flat-end set screw 17-23. The connecting screw 17-24 is connected to the detachment device 14.

[0039] In this embodiment, there are two umbrella covers 17-3, namely a small umbrella cover and a large umbrella cover. Both are integral structures that cover the outside of the central component. The outer sides of both the small umbrella cover and the large umbrella cover are provided with multiple layers of umbrella skirts. The outer diameter of the uppermost and lowermost umbrella skirts of the small umbrella cover is larger than the outer diameter of the umbrella skirts between them. The outer diameter of the uppermost and lowermost umbrella skirts of the large umbrella cover is larger than the outer diameter of the umbrella skirts between them.

[0040] The insulation structure of the small and large umbrella covers and the multi-layered umbrella skirts has been optimized in terms of spacing and height, effectively increasing the creepage distance and significantly improving the anti-pollution flashover capability. The internal insulation has been optimized by improving the core rod diameter, hardware insertion depth, and umbrella cover parameters, such as a core rod diameter of 32mm, a hardware insertion depth of 40mm, a large umbrella skirt diameter of 165mm, and a small umbrella skirt diameter of 93mm, to ensure uniform electric field distribution and meet mechanical strength requirements. The whole system is based on an adjustable fixed-line assembly, which highly integrates functional modules such as live-line working, wind protection, and lightning protection. The structure is compact, the performance is reliable, and the structure and function are truly integrated.

[0041] The upper and lower surge arresters form a discharge gap, inside which are resistive elements 17-7, used in conjunction with the disconnector 14 and the metal stranded wire 15. When the internal surge arrester malfunctions or the voltage reaches its maximum value, the disconnector 14 automatically detaches, but because it is connected by the metal stranded wire 15, it will remain suspended in the air and connected to the steel foot. Therefore, it will not fall to the ground and pose a risk of falling objects from a height. Maintenance personnel do not need to climb the pole; they can determine if the equipment has malfunctioned from the ground. Furthermore, this invention features a surge arrester anti-drop-off structure, facilitating operation and maintenance.

[0042] The insulator employs a precise internal structural design, encapsulating core surge protection components such as zinc oxide resistance sheets and series discharge gaps within the inner cavity of the lower large umbrella sleeve. This integrated encapsulation process ensures the sealing and stability of the internal components, effectively reducing the overall product size and avoiding the risks of wind swaying, insufficient installation space, and mechanical damage associated with external components. Furthermore, traditional surge arresters use disc-shaped resistance sheets placed inside a core rod. If the resistance sheet ruptures, the insulator will shatter and lose its supporting capacity, leading to the conductor fixing the surge arrester falling off. This invention innovatively surrounds the core 17-6 with an annular resistance sheet 17-7. The rupture of the resistance sheet 17-7 will not affect the integrity of the core 17-6, thus preventing the insulator from losing its supporting function and avoiding the conductor falling-off hazard that occurs with traditional structures.

[0043] In Embodiments 1 and 2, the umbrella skirt has a planar design on both the upper and lower ends, and clamping guide grooves are provided on the upper fitting 17-1 and the lower fitting 17-2. This ensures that the robot's end effector is stable and does not slip during clamping and handling for robot operations; and it also has strong anti-icing and anti-fouling capabilities.

[0044] The installation method in Implementation 1 is the same as that in Implementation 2. When it is necessary to install an insulator, the operator connects the top of the insulating rod to the operating ring 8 of the operating screw 3, or connects the operating end of the live-line working robot to the operating ring 8. By rotating the insulating rod, the operator drives the operating screw 3 to rotate. Since the operating screw 3 is threadedly connected to the threaded block 6, the operating screw 3 moves downward while rotating, causing the end of the pressure cover 1 with the upper groove 10 to be lifted, and the wire is placed in the lower groove 9. Rotating the insulating rod in the opposite direction causes the operating screw 3 to rotate, and the operating screw 3 moves upward, causing the end of the pressure cover 1 with the upper groove 10 to fall down and fix the wire in the wire clamping groove.

[0045] Both Embodiment 1 and Embodiment 2 allow for live-line work operations manually or using live-line working robots, providing wind protection. The latter adds lightning protection to the former. For distribution network lines in ordinary and windy areas, live-line workable windproof insulators can be selected; for heavy lightning areas and important lines, live-line workable integrated windproof and lightning protection insulators can be selected. Compared to traditional lines, where surge arresters need to be connected separately to the line, line nodes are prone to failure. Live-line workable integrated windproof and lightning protection insulators integrate the surge arrester and insulator into one device, reducing the number of connection nodes when using surge arresters separately and reducing the equipment failure rate.

7. A novel integrated insulator for live-line work as described in claim 5, characterized in that: The top of the upper fitting (17-1) is the lower base (4). The lower base (4) has an upper drain rod (16) on one side. The upper drain rod (16) is also covered with a buffer pad (7) on the outside, and is integrated with the buffer pad (7) in the lower groove (9) of the lower base (4). The current inlet seat (17-13) is equipped with a lower drain rod (18) by a flat-end set screw (17-22).

8. A novel integrated insulator for live-line work as described in claim 3, characterized in that: The lower fitting (17-2) is provided with a steel foot (17-21), and the bottom of the insulator body (17) is provided with a release device (14), which is connected to the steel foot (17-21) through a metal stranded wire (15).

9. A novel integrated insulator for live-line work as described in claim 4 or 5, characterized in that: The umbrella skirt is flat, and clamping guide grooves are provided on the upper hardware (17-1) and the lower hardware (17-2).

10. An installation method for a novel integrated insulator capable of live-line work, based on claims 1-9, characterized in that: When an insulator needs to be installed, the operator connects the top of the insulating rod to the operating ring (8) of the operating screw (3), or connects the end effector of the live-line working robot to the operating ring (8). By rotating, the operating screw (3) is driven to rotate. Since the operating screw (3) is threadedly connected to the threaded block (6), the operating screw (3) moves downward while rotating, causing the end of the pressure cover (1) with the upper groove (10) to be lifted, and the wire is placed in the lower groove (9). Rotating in the opposite direction causes the operating screw (3) to rotate. The operating screw (3) moves upward, causing the end of the pressure cover (1) with the upper groove (10) to fall down and fix the wire in the wire clamping groove.
