Technical Field

[0001] This application relates to the field of power fittings technology for power transmission line equipment, specifically a side-binding bolt insulated clamp for power distribution networks. Background Technology

[0002] In situations where installation space is extremely limited, such as at substation outgoing lines, tower corners, or when obstructed by other lines and equipment, the operable space around the insulator is small. Traditional top-binding methods are either difficult to implement due to the large force required to place the conductor into the top groove, or they are limited in use because top installation causes excessive bending stress on the conductor. In such cases, methods of binding the conductor from the side of the insulator, such as the PVC side-binding structure for conductor fixing disclosed in patent document CN209358201U, have become a more efficient and reliable fixing method.

[0003] Currently, the mainstream conductor fixing products used for fixing insulators and conductors, such as traditional metal binding wire and pre-stranded binding wire, have significant drawbacks: Traditional binding processes are prone to ionization discharge due to gaps between the binding wire and the conductor, which can burn the insulation layer. Under long-term operation or natural disasters, this can easily lead to strand breakage and power outages caused by conductor detachment. While pre-stranded binding wire offers some improvement, it is inconvenient for high-altitude operations and may still damage the conductor insulation layer. In addition, the binding wire installation method has the following disadvantages: low construction efficiency, complete reliance on manual operation, and high labor intensity; difficulty in uniformizing binding quality and tightness, as excessive tightness may damage the conductor, while excessive looseness may cause the conductor to slip or detach; long-term friction between the metal wire and the conductor and insulator may wear down the outer protective layer of the conductor and the enamel surface of the insulator, affecting the long-term operational safety and lifespan of the line.

DETAILED DESCRIPTION

[0017] ​​​With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application.

[0018] The application provides a power distribution network side binding bolt insulation wire clamp, which is connected into a whole by an insulator fixing ring 1 and two wire fixing rings 2 on both sides through a bonding process, and is fastened to a wire 5 through a bolt connection pair, and the whole material of the clamp uses composite EPDM (Ethylene Propylene Diene Rubber).

[0019] The insulator fixing ring 1 is used for fixing the neck part or side wire groove of the insulator 4 from the side, and the wire fixing ring 2 is used for fixing the wire 5, the insulator fixing ring 1 comprises a middle annular open belt binding hoop part 11 and two connecting parts 12 on both sides, the binding hoop part 11 is in the shape of a semicircular ring, in order to match the inner wall of the binding hoop part 11 with the disc neck part of the insulator 4, the bending curvature of the semicircular ring is more than one kind, the bending curvature radius of the middle of the semicircular ring is smaller than the bending curvature radius of both sides, the bending curvature radius of both sides in the embodiment is 62 mm, which is suitable for the disc radius of the neck part of the standard insulator 4, and the bending curvature radius of the middle is 33 mm, and the vertical width of the whole belt binding hoop part 11 is 18 mm.

[0020] In order to enable the clamp to be stably fixed on the insulator with the disc radius of the neck part of 62 mm, the binding hoop part is designed to be thickened at the position overlapping with the disc between the connecting parts in the connecting direction of the connecting parts, the triangular thickening part 13 in the embodiment is 73° in the triangular angle close to the connecting part, and a first round corner 131 with a radius of 2 mm is arranged at the terminal edge of the triangular thickening structure of the clamp, the triangular thickening part 13 is arranged to enhance the mechanical strength of the clamp at the key stress position, and enable the clamp to be stably clamped on the insulator with the disc radius of the neck part of about 62 mm and prevent left and right shaking. In addition to the triangular thickening part, other shapes of thickening structures such as triangular thickening part with arc edge can also be used.

[0021] In order to enhance the self-cleaning ability of the clamp, prevent moisture retention, inhibit surface dirt accumulation and snow accumulation, the triangular thickening part 13 top surface is also provided with a hydrophobic triangular slope 132, and the end surface of the straight line part 22 far from the curved part 21 is also provided with a hydrophobic rectangular slope 221, the hydrophobic structure uses a convex columnar rhombus array, the top of the columnar rhombus is provided with a spherical dome structure with the rhombus as the bottom side, and the rhombus array is also covered with a waxy nanocrystal layer. In this embodiment, the triangular slope 132 has a slope of 11°, the rectangular slope 221 has a slope of 34°, the height of each convex rhombus top dome structure is 5µm, the diagonal length is 10µm, and the array spacing is 20µm. The diagonal of the long side of the array structure is parallel to the inclination direction, which macroscopically ensures the hydrophobic effect. The upper surface of the rhombus array structure is also covered with a layer of waxy nanocrystals, and the size of these nanostructures can be around 100-500nm. In this embodiment, the triangular slope 132 uses a thickness of 100nm, and the rectangular slope 221 uses a thickness of 300nm. Surface modification techniques such as spraying can be used for coverage. The micro-nano secondary structure makes the actual contact area of the water droplet with the solid surface very small, usually only 2-3% of the apparent contact area, the contact angle of the water droplet is greater than 150°, and the water droplet presents excellent lotus effect, so that the adsorption force of the solid surface to the water droplet becomes very weak, thereby greatly improving the insulation performance and aging resistance of the clamp in humid and harsh environments.

[0022] The inner envelope hole of the conductor fixing ring 2 is an open horseshoe structure in cross section, used for accommodating and fixing the power transmission conductor 5. The conductor 5 adapted to the line clamp in the embodiment has a diameter of 18 mm, matching the standard of overhead insulated distribution line conductor, including a conductor layer and an outer protective envelope layer. The outer protective layer is wrapped outside the conductor layer, the conductor layer is twisted by several aluminum single wires, and the material of the outer protective layer is cross-linked polyethylene (XLPE), which has strong insulation performance, heat aging resistance, environmental stress cracking resistance and corrosion resistance, and can effectively protect the internal multi-core aluminum stranded conductor. The open horseshoe structure includes a curved portion 21 and two straight portions 22 on both sides, the curved portion 21 is used to cover the conductor, and the straight portions 22 are used to fix the fasteners. In the embodiment, the two straight portions 22 are respectively a first side plate and a second side plate. In the embodiment, the total thickness of the clamped part of the conductor fixing ring 2 is the sum of the thickness of the first side plate, the thickness of the second side plate, the distance between the two side plates and the thickness of the bolt flange. In the embodiment, the thickness of the first side plate and the thickness of the second side plate are both 12 mm, the distance between the two side plates is 11 mm, and the thickness of the bolt flange is 2 mm. The total thickness of the clamped part of the conductor fixing ring 2 is 37 mm. According to the thickness size of the horseshoe conductor fixing ring 2 and considering that the insulation line clamp is a flexible part, the installation error may be large and other factors, the bolt length is 55 mm, that is, the bolt in the bolt connection pair in the embodiment is a hexagonal flange toothed bolt M8x55, and the nut is a hexagonal flange toothed nut M8. The toothed structure on the flange surface can effectively engage the outer surface of the line clamp straight portion 22, further enhancing the anti-loose performance.

[0023] In order to make the two inner surfaces fit after bolt fastening, prevent the aging of the line clamp inside, and at the same time have a certain reaction force, play the anti-loose effect of bolt connection, the thickness of the straight portion 22 of the conductor fixing ring 2 is greater than the thickness of the curved portion 21. For example, in the embodiment, the inner diameter of the curved portion 21 is 9 mm, the outer diameter is 18 mm, and the thickness is 9 mm. The size of the line clamp curved portion 21 and the structure of the conductor 5 form a tight, stable and reliable connection and effective clamping, while meeting the technical requirements of mechanical bearing. The thickness of the straight portion is 12 mm. This thickening design ensures that there is enough elastic deformation space at this part when the bolt is fastened, so that the two inner surfaces of the line clamp straight portion 22 can finally fit tightly, avoiding the entry of water and impurities into the line clamp inner surface due to the existence of gaps, and at the same time, a continuous reaction force is generated on the bolt, playing a good anti-loose effect.

[0024] In order to prevent the insulator 4 from rotating and slipping in the circumferential direction, an anti-skid array structure is arranged inside the insulator fixing ring 1. In this embodiment, the anti-skid array structure uses 26 strip-shaped semi-elliptical bodies 111 parallel to the axis of the insulator as each anti-skid unit. The short axis radius of each strip-shaped semi-elliptical body 111 is 2 mm, and the long axis radius is 7 mm. Through this design which imitates the roughness of the porcelain insulator surface, the friction coefficient with the porcelain body surface of the insulator 4 is increased. This structure is similar to the outer surface profile of the porcelain insulator, and ensures that a tight fit is formed on the circumference of the insulator. In addition to the shape of this embodiment, other shapes such as wave points, corrugations, etc. can also be used for the anti-skid array structure.

[0025] A conductor anti-skid structure is also arranged inside the curved part 21 of the conductor fixing ring 2. The conductor anti-skid structure is used to prevent the conductor from rotating axially. In this embodiment, the conductor anti-skid structure uses 6 units to form an anti-skid tooth shape. Each unit uses a rectangular strip 23 perpendicular to the axis of the conductor 5. The width of the rectangular strip 23 is 2 mm, and the spacing between the rectangular strips 23 is 3 mm. A second round corner 231 is designed at the short side line of the rectangle. In this embodiment, the radius of the second round corner 231 is 2 mm. This structure can effectively engage the outer protective layer of the conductor 5, increase the friction, and prevent the conductor 5 from axially moving when subjected to external force.

[0026] For the fixing of the insulator fixing ring 1 and the conductor fixing ring 2, a high-precision mechanical positioning and high-strength adhesive combination is adopted, which realizes the reliable connection of the side binding type insulating clamp at a specific spatial angle, effectively improving the structural adaptability and mechanical stability of the clamp. This method not only focuses on the pretreatment of the bonding interface and the control of the adhesive layer, but also adopts a positioning system based on the bolt hole as a reference to ensure that the assembly maintains accurate spatial alignment during the curing process, thereby achieving high-strength bonding effect after the horizontal distance between the two horseshoe-shaped conductor fixing rings is predetermined. The insulator fixing ring 1 and the conductor fixing ring 2 of the present embodiment adopt the following bonding process: a) surface cleaning and roughening: use anhydrous alcohol to repeatedly wipe the bonding surfaces of the insulator fixing ring 1 and the conductor fixing ring 2, and use 120 mesh sandpaper to polish the bonding surfaces of the two components. When polishing, ensure that the entire bonding surface is evenly polished, so that the originally smooth rubber surface forms a certain roughness to increase the contact area between the adhesive and the rubber surface, thereby improving the mechanical bonding force of the bonding. b) marking: mark the outer surface of the connecting part 12 of the insulator fixing ring 1 and the straight part 22 of the conductor fixing ring 2, and use a marking needle to mark the positioning line in the horizontal and vertical directions of the center line of the bolt hole. c) selection and application of adhesive: use a brush to apply a polyisocyanate adhesive to the pretreated bonding surfaces of the two components. When applying the adhesive, pay attention to control the thickness of the adhesive layer, and the thickness of the adhesive layer is generally controlled between 0.5mm. d) installation and positioning: place the conductor fixing ring 2 in the positioning groove on the same horizontal plane, ensure that the horizontal distance between the two fixing rings is a fixed value, insert the positioning pin into the bolt hole of the conductor fixing ring 2, and the insulator fixing ring 1 is preliminarily positioned according to the horizontal direction by cooperating with the positioning pin. Make the positions of the outer surface marking lines of the two fixing rings collinear, and perform pressing operation. 4) curing operation: after tightly fitting the two fixed components, wait for 2-3 hours for curing.

[0027] In addition to the above method, other methods such as bonding first and then punching can also be used.

[0028] The side binding type insulating wire clamp of the present scheme is suitable for 10kV distribution line with neck diameter insulator 4, such as needle type insulator, column type insulator, butterfly type insulator, etc., and is fixed by binding the thinnest neck part of the insulator 4 between porcelain discs. When used, a) preparation: prepare a side binding type bolt insulating wire clamp of the present scheme, a M8 spanner, and a cleaning cloth. Confirm the model of the target insulator, and the neck disc radius should be 62mm, and the outer diameter of the fixed conductor should be 18mm. b) preliminary positioning: the conductor fixing ring 2 of the clamp is opened upwards, and is sleeved into the neck disc of the insulator 4 from the side. When operating, the triangular thickening part 13 on the inner wall of the insulator fixing ring 1 is clamped on the bottom edge of the disc of the insulator 4. Lightly press the anti-slip structure composed of 26 strip-shaped semi-elliptical bodies 111 on the inner wall of the insulator fixing ring 1 to preliminarily contact the porcelain surface of the insulator 4. c) placing the conductor: place the power transmission conductor 5 into the horseshoe-shaped opening of the conductor fixing ring 2, so that the conductor 5 tightly abuts the arc-shaped inner wall of the bending part 21. d) tightening the bolt: pass the M8×55 hexagonal flange surface toothed bolt through the bolt hole and screw the matching hexagonal flange surface toothed nut from the other side, until the hand feels tight. Then, use the spanner to tighten the nut gradually and uniformly to apply pre-tightening force. During the tightening process, it can be observed that the straight part of the conductor fixing ring 2 is elastically deformed, the distance between the two inner surfaces gradually decreases, and the conductor 5 is tightly held. The toothed structure on the flange surface of the bolt and the nut also simultaneously bites into the rubber surface, playing a loosening prevention role. e) inspection and confirmation: after installation is completed, check whether the clamp is installed in place. Confirm that the insulator fixing ring 1 is firmly clamped on the insulator 4 and does not shake left and right; gently pull the conductor 5, and the conductor 5 does not axially move in the clamp; check whether the flange surface of the bolt and the nut is pressed tightly without loosening.

[0029] In order to effectively prevent the self-loosening of the clamp after installation and timely monitor the state of the clamped conductor 5, the present embodiment also arranges a surface acoustic wave sensor on the clamp, which realizes the corresponding function in combination with the matched reader / writer and monitoring system. The surface acoustic wave sensor is a passive sensor, which excites and reflects the modulated signal carrying state information by receiving radio frequency signals, and returns the signal to the reader / writer.

[0030] Specifically, the surface acoustic wave sensor is installed on the inner side of the insulator fixing ring 1 opposite to the insulator 4 and the wire fixing ring 2 for monitoring the strain of the insulator fixing ring 1. In the embodiment, one first surface acoustic wave sensor 6a and two second surface acoustic wave sensors 6b are used. The first surface acoustic wave sensor 6a is located at the inner side center point position of the binding hoop part 11 of the insulator fixing ring 1 facing the insulator 4, and the second surface acoustic wave sensor 6b is located at the position of the connecting part between the connecting part 12 and the triangular thickening part 13 of the insulator fixing ring 1 facing the inner side center line of the wire fixing ring 2. These two positions are the maximum positions of the maximum deformation and bending stress of the insulator fixing ring 1. When the surface of the insulator fixing ring 1 is treated and the surface acoustic wave sensor is installed, the low-temperature plasma cleaning is performed on these points, and the surface is activated under the working conditions of a power of 300 W and a treatment time of 60 seconds. Subsequently, the high-precision dispensing machine is used to coat the heat-conducting silicone glue, and the passive surface acoustic wave sensor is accurately attached to the specified position. The installation is completed under the conditions of a pressure of 0.05 MPa and a temperature of 80°C for 1 hour. When the insulator fixing ring strain monitoring system is built and tested, the system is composed of a reader / writer, a handheld antenna and a background data processing software. First, the test insulator is tested: the installed clamp is assembled on the test insulator, and the torque of the fastening bolt is gradually applied to the specified value. The reader / writer successfully reads the initial values of the phase and frequency of the surface acoustic wave sensor reflection signal, and the initial value of the fastening strain of the clamp is displayed in real time through software calculation; then the safety threshold of signal deviation is determined through laboratory fatigue test, simulation overload and other working conditions; when the deviation of real-time monitoring data relative to the initial value exceeds the threshold, the system automatically triggers the early warning. In the installation site, the handheld reader / writer is used to test the installed clamp, and the system successfully receives the sensor signal and displays stable readings. By slightly pulling the clamp to simulate loosening, the background software can immediately monitor the significant change of the signal parameters and issue a warning prompt, thereby verifying the effectiveness and sensitivity of the entire monitoring system.

[0031] Another installation in the wire fixing ring 2 bending part 21 inside, for monitoring the temperature of the wire 5, in this embodiment using two third surface acoustic wave sensor 6c, each located in two wire fixing ring 2 bending part 21 inside the bottom center, the part is to form the pressure contact force area, that is, the current path on the key node and the most prone to overheating position. Temperature monitoring system building and testing, the system consists of UHF frequency band reader, handheld antenna and background data processing and early warning platform, first in the laboratory constant temperature conditions, the installation of the wire 5 and the clamp assembly fixed on the insulator 4, and give the wire 5 through the rated current, after its temperature is stable, record the frequency of the surface acoustic wave sensor reflection as the reference frequency, the corresponding temperature is the reference temperature. For early warning, can set two temperature warning threshold: the first warning set to relative temperature rise ΔT, such as higher than the ambient temperature 30 DEG C; the second warning alarm value set to a higher absolute temperature T2, such as 75 DEG C. At the same time, set the temperature rise rate threshold, such as 5 DEG C / min, temperature rise too fast is the strong sign of fault arc or serious contact; again verify the warning: if the background monitoring system receives the warning report, operation and maintenance personnel according to the alarm information arrived at the scene, using handheld infrared thermal imager for review, confirm that the clamp wire fixing ring 2 bending part 21 exists obvious overheating area, observation and surface acoustic wave sensor reported temperature trend and the value of high consistency.

[0032] The above is only the preferred embodiment of the present application, but the scope of protection required by the present application is not limited to this, any skilled in the art of the technical personnel in the technical range of the present application, according to the technical scheme and the inventive concept of the present application to equivalent replacement or change, should be covered in the protection scope of the present application.
