Abstract
Description
Technical Field
[0001] The present invention relates to the field of auxiliary tools for 10kV power supply line operations, and particularly to a special operation tool for live connection lead clamps. Background Art
[0002] The 10kV distribution network is a power infrastructure that directly supplies electric energy to users. To improve the power supply reliability of the 10kV distribution network, the 10kV distribution network needs to be frequently upgraded, transformed, and operated and maintained. In the work of upgrading, transforming, operating, and maintaining the 10kV distribution network, a large number of operations of connecting branch diversion wires to the main transmission line are involved. An important auxiliary tool for connecting branch diversion wires to the main transmission line is a connection lead clamp used to electrically connect the diversion wire to the main transmission line.
[0003] Currently, the commonly used live connection lead clamps for 10kV distribution networks mainly include: bolt J-type line clamps, bolt C-type line clamps, and ejection wedge-type line clamps. Among them: First, the bolt J-type line clamp is composed of 2 J-shaped elements with wedges and 1 connecting bolt. The longitudinal tightening force of the bolt is used to make the wedges of the upper and lower J elements wedge into each other and simultaneously clamp the main transmission line and the diversion wire, and the electrical conduction between the main transmission line and the diversion wire is realized through the J-type line clamp. Its advantage is that the longitudinal tightening force of the bolt and the lateral force of the two J elements acting on the wire do not interfere with each other. Even if the tightening force decreases after long-term operation of the bolt, good contact between the line clamp and the wire can still be ensured. Its problem is that the existing J-type line clamps generally use casting non-elastic materials and cannot provide elastic deformation after installation. At the same time, limited by the overall length of the line clamp, there is a heating phenomenon in large-load lines after connection, which greatly affects its reliability. Second, the bolt C-type line clamp is composed of 1 C-type element, 2 hinged wedges, and 1 bolt. The longitudinal tightening force of the bolt is used to make the left and right hinged wedges wedge into the C-type element groove to respectively clamp the main transmission line and the diversion wire and realize electrical connection. Its advantage is that the connection performance is better. Its problem is that due to the small opening of the C-type element and the separable and flexible movement of the hinged wedges, the C-type line clamp is troublesome to install and cannot be installed with an insulating rod. Third, the ejection wedge-type line clamp is composed of 1 C-type element for fitting the main transmission line and the diversion wire and a wedge for fastening, and is equipped with a special ejection installation tool (including an ejection chip). During installation operation, the ejection impact force generated by the combustion of gunpowder inside the ejection core triggered by hitting the installation tool is used to press the wedge into the C-type element to realize the electrical connection between the main transmission line and the diversion wire. Its advantage is that there is no need to worry about the increase in contact resistance caused by the reduction of the element tightening force, and because the tightening force of the line clamp is large after ejection, the current-carrying capacity of the wedge-type line clamp is much higher than that of other line clamps. However, its existing problems are: high cost and inability to operate indirectly.
[0004] As can be seen from the above analysis, although the commonly used live connection lead clamps for 10 kV distribution networks, such as bolt J type, bolt C type, and ejection wedge type, each have their own advantages, they all have obvious deficiencies. Therefore, it is necessary to develop a more suitable live connection lead clamp for 10 kV distribution networks and a supporting dedicated operation tool for indirect operation.

[0034] The wire clamping slider 2 is a wedge-shaped structural member that slidably cooperates with the wire clamping portion 11 of the main body 1. The wire clamping slider 2 is mainly composed of a body 21 and a sliding sleeve portion 22. The body 21 is a wedge-shaped structural member that cooperates with the wire clamping portion 11 of the main body 1. A wire clamping groove 21-1 that is arranged horizontally, recessed downward, and has an arc-shaped longitudinal section is provided at the upper end of the body 21. During use, the wire clamping groove 21-1 at the upper end of the body 21 cooperates with the wire clamping groove 11-4 of the wire clamping portion 11 to clamp the wire of the power transmission line. As a preferred method, a groove that is recessed backward is also provided on the body 21 as a strengthening groove 21-2. On the one hand, the strengthening groove 21-2 can reduce the weight of the wire clamping slider 2, and on the other hand, it can increase the structural strength of the wire clamping slider 2. The sliding sleeve portion 22 is arranged in cooperation with the sliding sleeve structure of the wire clamping portion 11; the sliding sleeve portion 22 is integrally composed of a vertical plate (not marked in the figure) that is integrally connected to the rear end of the body 21 and a socket plate 22-1 that is inclined horizontally. The vertical plate and the socket plate 22-1 of the sliding sleeve portion 22 form a structure with an inverted L-shaped longitudinal section. The wire clamping slider 2 can be slidably sleeved with the sliding sleeve structure of the wire clamping portion 11 through its sliding sleeve portion 22. As a preferred method, a check tooth 22-1-1 that cooperates with the first check tooth provided on the upper end surface of the lower plate 11-5 of the wire clamping portion 11 is provided on the lower end surface of the socket plate 22-1 of the sliding sleeve portion 22. During use, the check tooth 22-1-1 provided on the lower end surface of the socket plate 22-1 of the sliding sleeve portion 22 cooperates with the first check tooth provided on the upper end surface of the lower plate 11-5 of the wire clamping portion 11, so that the wire clamping slider 2 cannot easily slide left and downward to loosen the clamping of the wire after clamping the wire, thereby enabling the live connection lead clamp to be firmly set on the wire for a long time without loosening.
[0035] Both the main body 1 and the wire clamping slider 2 are made of conductive materials, preferably aluminum alloy.
[0036] The first nut 3 is fixedly arranged at the lower left of the rear end face of the body 21 of the wire clamping slider 2; the second nut 4 is fixedly arranged on the rear end face of the rear plate 11-1 of the wire clamping portion 11 of the main body 1 and is located on the right side of the bolt relief groove hole 11-1-1 of the rear plate 11-1.
[0037] The driving bolt 5 is threadedly connected to the first nut 3 and the second nut 4 respectively. During use, when the driving bolt 5 is tightened by using a supporting tool, the wire clamping slider 2 can slide from the lower left to the upper right in the wire clamping portion 11 of the main body 1 to clamp the wire.
[0038] The retaining ring 6 is provided as a preferred method. The retaining ring 6 is arranged on the driving bolt 5 and is located on the right side of the first nut 3. The retaining ring 6 is used to prevent the main body 1 and the wire clamping slider 2 from being damaged due to excessive tightening under the action of the driving bolt 5.
[0039] The check valve bolt 7 is set as a preferred mode. Correspondingly, bolt holes are respectively provided in the right part of the lower plate 11-5 of the wire clamping part 11 of the main body 1 and the right part of the socket plate 22-1 of the sliding sleeve part 22 of the wire clamping slider 2. During use, after the wire clamping slider 2 clamps the wire, the check valve bolt 7 passes through the bolt hole of the lower plate 11-5 of the wire clamping part 11 of the main body 1 and is connected to the bolt hole of the socket plate 22-1 of the sliding sleeve part 22 of the wire clamping slider 2, so that the live connection lead clamp can be firmly set on the wire for a long time without loosening.
[0040] For the aforementioned live connection lead clamp, the joint resistance and temperature rise during power-on in the use experiment are briefly described as follows:
[0041] According to the GB / T 2317.3 standard for electric power fittings, for compression-type fittings, if their resistance value is not greater than the resistance value of the reference wire of the same length as the fitting, the electrical performance meets the requirements; for non-compression-type fittings, if their resistance value is not greater than 1.1 times the resistance value of the reference wire of the same length as the fitting, the test passes. The aforementioned live connection lead clamp belongs to non-compression-type fittings, so its joint resistance with the wire should not be greater than 1.1 times the resistance of the wire of the same length. Verified by experiments, the joint resistance of the aforementioned live connection lead clamp is equal to 0.88 times the resistance of the wire of the same length before temperature rise and 0.90 times the resistance of the wire of the same length after temperature rise, meeting the national standard requirements. In the temperature rise test of the aforementioned live connection lead clamp when bearing the load current of the distribution network line, when the loop current is 300A, the surface temperature of the clamp is lower than the surface temperature of the wire, and the surface temperature of the copper drainage wire is stable at 42 degrees; when the loop current is 500A, the surface temperature of the clamp is lower than the surface temperature of the wire, and the surface temperature of the copper drainage wire is stable at 62 degrees. It can be seen from the test that the resistance of the joint part between the aforementioned live connection lead clamp and the wire is small, and in addition, the clamp has a large heat dissipation area, so the surface temperature of the clamp is lower than the surface temperature of the wire. Therefore, the aforementioned live connection lead clamp can safely complete the connection of the drainage wire of the 10kV distribution line.
[0042] See Figures 5 to 8 The special operating tool for the live connection lead clamp of this embodiment mainly consists of a base body 100, a wire clamp main body limiting claw 101, a drainage wire limiting claw 102, a sliding bracket 103, an electric socket wrench 104, a transmission part 105, a spring connection pin 106 and a spring 107.

The first wedge-shaped part 100-1 is provided with a relief notch 100-1-2 at the left end of its main body accommodating groove 100-1-1, and the relief notch 100-1-2 is used to make room for the second nut 4 of the aforementioned live connection lead clamp during use. Two bolt relief grooves 100-2-1 are provided on the right side of the second wedge-shaped part 100-2, divided into upper and lower parts. The bolt relief grooves 100-2-1 are used to make room for the connection bolts that connect the lead wire connection part 12 of the main body 1 of the aforementioned live connection lead to the lead wire during use; two sliding grooves 100-2-2 are provided. The two sliding grooves 100-2-2 are inclined from the lower left to the upper right on both sides of the upper part of the second wedge-shaped part 100-2; two lifting connection screw holes 100-2-3 are provided in the middle of the second wedge-shaped part 100-2, and the lifting connection screw holes 100-2-3 are used to be connected to a lifting tool such as an insulating operating rod during use to lift the special operating tool for the live connection lead clamp of this embodiment.
[0044] The wire clamp body limiting claw 101 is integrally composed of an upper plate arranged in the front-back direction and a front plate arranged in the up-down direction. The wire clamp body limiting claw 101 is integrally or fixedly connected to the upper left end face of the first wedge-shaped part 100-1 by the lower end face of the rear part of its upper plate. The middle front part of the upper plate of the wire clamp body limiting claw 101 protrudes forward from the first wedge-shaped part 100-1, and the front end of the upper plate of the wire clamp body limiting claw 101 is vertically and integrally connected to the front plate.
[0045] The lead wire limiting claw 102 is fixedly arranged on the front end face of the second wedge-shaped part 100-2 and is located on the left side of the two bolt relief grooves 100-2-1 of the second wedge-shaped part 100-2; the lead wire limiting claw 102 is used to limit the combination after the lead wire connection part 12 of the main body 1 of the aforementioned live connection lead is connected to the lead wire during use. The lead wire limiting claw 102 is integrally composed of a vertical plate arranged in the up-down direction and a horizontal plate arranged in the left-right direction. The lead wire limiting claw 102 is integrally or fixedly connected to the front end face of the second wedge-shaped part 100-2 by the rear end of its vertical plate. The horizontal plate of the lead wire limiting claw 102 is located in front of its vertical plate, and the left-right cross section of the lead wire limiting claw 102 is L-shaped.
[0046] The sliding bracket 103 is a structural member configured to slidably cooperate with the chute 100-2-2 of the second wedge portion 100-2. The sliding bracket 103 can slide above the second wedge portion 100-2 relying on the two chutes 100-2-2 of the second wedge portion 100-2.
[0047] The electric socket wrench 104 is a commercially available component. The electric socket wrench 104 has a socket nut 104-1. The start, stop, forward rotation, and reverse rotation of the electric socket wrench 104 are all controlled by its supporting remote control. The electric socket wrench 104 is fixedly arranged on the sliding bracket 103, and the socket nut 104-1 of the electric socket wrench 104 extends obliquely upward to the right relative to the sliding bracket 103. During use, after the socket nut 104-1 of the electric socket wrench 104 is sleeved with the driving bolt 5 of the aforementioned live connection lead clamp, the rotation of the electric socket wrench 104 drives the driving bolt 5 to perform a tightening action, and then the driving bolt 5 drives the wire clamping slider 2 to slide from the lower left to the upper right in the wire clamping portion 11 of the main body 1 to clamp the wire of the transmission line.
[0048] The transmission member 105 is a bent strip-shaped plate member. The transmission member 105 is pin-connected to the rear end of the second wedge portion 100-2 by a configured first connecting pin 105-1, and the transmission member 105 is pin-connected to the rear end of the sliding bracket 103 by a configured second connecting pin 105-2. A spring connecting ear (not marked in the figure) is provided at the upper right part of the upper end of the transmission member 105, and an operation connecting hole 105-3 is provided at the lower end of the transmission member 105. The operation connecting hole 105-3 is used to cooperate with a corresponding operation tool (such as an insulating operating rod with a hook at the upper end) during use to realize the sleeving and loosening actions of the socket nut 104-1 of the electric socket wrench 104 and the driving bolt 5 of the aforementioned live connection lead clamp.
[0049] The spring connecting pin 106 is fixedly arranged at the middle position of the junction of the first wedge portion 100-1 and the second wedge portion 100-2 of the base body 100. One end of the spring 107 is hooked to the spring connecting pin 106, and the other end of the spring 107 is hooked to the spring connecting ear of the transmission member 105. The function of the spring 107 is that when it is necessary to sleeve the socket nut 104-1 of the electric socket wrench 104 with the driving bolt 5 of the aforementioned live connection lead clamp during use, the transmission member 105 is pulled downward to overcome the tension of the spring 107, so that the electric socket wrench 104 relies on the sliding bracket 103 to retreat obliquely downward to the left to facilitate adjusting the position to sleeve with the driving bolt 5 of the live connection lead clamp and loosen from the driving bolt 5 after the live connection lead clamp clamps the wire. When the socket nut 104-1 of the electric socket wrench 104 is sleeved with the driving bolt 5 of the live connection lead clamp and the driving process is implemented, the spring 107 can use its tension to ensure that the socket nut 104-1 and the driving bolt 5 of the live connection lead clamp remain sleeved without loosening.
[0050] See also Figure 9 and Figure 10 , the dedicated operating tool for the live lead wire clamp of this embodiment, the usage of which when used, is briefly described as follows:
[0051] First, fit the drain wire 108 with the drain wire connecting part 12 of the aforementioned live lead wire clamp body 1, and use two drain wire connecting bolts 109 to fix the drain wire 108 on the front end surface of the drain wire connecting part 12, and then place the live lead wire clamp with the drain wire 108 installed in the dedicated operating tool for the live lead wire clamp of this embodiment.
