Description

Technical Field

[0001] The utility model belongs to the technical field of power equipment, and particularly relates to an insulating shunt wire auxiliary clamp. Background Art

[0002] When performing the work of live disconnecting and connecting the leading wire of an open-circuit cable, since many current 10kV cable terminal leading wires adopt rectangular copper-aluminum equipment clamps. When using an insulating shunt wire to construct a parallel circuit for the capacitive current of the cable, due to the end of the shunt wire being an arc-shaped opening and unable to be reliably connected to the equipment clamp, it is only possible to strip the insulating wire to install the shunt wire, and one operation may take more than one and a half hours, seriously affecting the operation efficiency.

[0003] To solve this problem, an intermediate connecting device was developed. One end can be connected to the equipment clamp, and the other end can be reliably connected to the arc-shaped insulating shunt wire. The team members were inspired by the clamp of the grounding wire that can often be seen in daily work, so they improved it. The middle of the clamp was made into an arc shape, and both sides were made into flat shapes, making it applicable to both copper lugs and equipment clamps. This can reduce the labor intensity of the operators in stripping the wire, and improve the efficiency and safety level of live working. Content of the Utility Model

[0004] The purpose of the utility model is to provide an insulating shunt wire auxiliary clamp, which can reduce the labor intensity of the operators in stripping the wire, and improve the efficiency and safety level of live working.

[0006] The insulating shunt wire auxiliary clamp is located between the insulating shunt wire and the cable end.

[0007] The end of the insulating shunt wire is an arc-shaped structure and is provided with a wiring hole.

[0008] The cable end has a copper-aluminum equipment clamp for connection.

A threaded rod is installed on one corresponding side wall of the U-shaped frame for driving the clamping plate to move or approach the other side wall of the U-shaped frame. A through hole for the threaded rod to pass through is provided on the side wall of the U-shaped frame. The threaded rod is in threaded cooperation with the through hole. One end of the threaded rod is rotatably connected to the central position of the clamping plate.

[0010] The other end of the threaded rod is vertically fixed with a handle.

[0011] Further, between the corresponding side walls of the U-shaped frame is a connecting portion, and a raised slide rail is formed at the portion of the connecting portion corresponding to the inner groove. One side of the clamping plate corresponding to the slide rail has a chute.

[0012] Further, a screw sleeve is installed at the position of the perforation on the single-side side wall of the U-shaped frame. The screw sleeve is sleeved and fixed on the perforation for threaded cooperation with the threaded rod.

[0013] Further, the side wall of the U-shaped frame corresponding to the cooperation with the clamping plate has an arc-shaped groove, and the arc-shaped groove is formed by an inward arc-shaped depression of the portion of the U-shaped frame corresponding to the inner groove.

[0014] Further, an anti-detachment cap is installed at the end of the handle. The anti-detachment cap is spherical, and the anti-detachment cap is provided with a jack for inserting the end of the handle, and the jack is in threaded cooperation with the handle.

Detailed Embodiment

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] As shown in Figures 1 - 3 the figure: The insulating drainage line auxiliary clamp is located between the insulating drainage line 5 and the cable end. The end of the insulating drainage line 5 is an arc-shaped structure and is provided with a wiring hole; a perforation with a circular cross-section.

[0026] The cable end has a copper-aluminum equipment clamp 4 for connection; one end of the copper-aluminum equipment clamp has a clamping piece for fixing the bare wire end of the cable, and the other end is a rectangular copper sheet composite end.

[0027] It includes a U-shaped frame 1, which is also approximately a C-shaped structure, with one side being the open side. A clamping plate 2 is installed in the corresponding inner groove of the U-shaped frame 1. A threaded rod 31 is installed on the corresponding side wall of the U-shaped frame 1 for driving the clamping plate 2 to move or approach the other side wall of the U-shaped frame 1. The side wall of the U-shaped frame 1 has a perforation for the threaded rod to pass through. The threaded rod 31 is in threaded cooperation with the perforation. One end of the threaded rod 31 is rotatably connected to the central position of the clamping plate 2; rotating the threaded rod drives the clamping plate to move along one side wall of the U-shaped frame towards the other side wall. The other side wall of the U-shaped frame serves as a fixed clamping arm, the clamping plate serves as a movable clamping arm, and the middle serves as a clamping groove for placing the corresponding rectangular end of the copper-aluminum equipment clamp.

[0028] A handle 3 is vertically fixed to the other end of the threaded rod 31. The handle is not only used to rotate the threaded rod but also serves as the wiring end of the insulating drainage line. The cross-section of the handle is a circular rod, which can just be inserted into the corresponding circular wiring hole of the insulating drainage line.

[0029] 1. Before operation, first reliably connect the auxiliary clamp to the cable terminal, and connect it to the copper nose or copper-aluminum equipment clamp with a chuck;

[0030] 2. After ensuring that the auxiliary clamp is firmly connected, reliably connect the insulating drainage line to the rotating handle, and then insulate and shield the connection part;

[0031] 3. Connect the other end of the insulating drainage line to the arc extinguishing switch, and then complete the work of disconnecting and connecting the no-load cable lead according to the operation steps;

[0032] 4. Open the arc extinguishing switch, first disconnect the connection between the insulating drainage line and the arc extinguishing switch, and then disconnect the connection between the insulating drainage line and the auxiliary clamp;

[0033] 5. Remove the auxiliary clamp.

[0034] As shown in Figure 3As shown in the figure: between the corresponding side walls of the U-shaped frame 1 is a connecting part. The part of the connecting part corresponding to the inner groove forms a raised sliding rail 11. One side of the clamping plate 2 corresponding to the sliding rail 11 has a sliding groove 21. When the threaded rod is rotated, it drives the clamping plate to move stably horizontally. A screw sleeve 12 is installed at the position of the perforation on the single-side side wall of the U-shaped frame 1. The screw sleeve 12 is sleeved and fixed in the perforation for threaded cooperation with the threaded rod 31. The side wall of the U-shaped frame 1 corresponding to the cooperation with the clamping plate 2 has an arc-shaped groove 13, and the arc-shaped groove 13 is formed by an inward arc-shaped depression of the part of the U-shaped frame corresponding to the inner groove. It is used for the wiring of the copper nose at the end of the cable. Since the copper nose is a cylindrical structure, the arc-shaped groove can better clamp and stabilize it. A detachable prevention cap 32 is installed at the end of the handle 3. The detachable prevention cap 32 is spherical. The detachable prevention cap 32 is provided with a jack 33 for inserting the end of the handle 3, and the jack 33 is in threaded cooperation with the handle 3. The detachable prevention cap is a sphere made of insulating material, which is used to prevent the insulating lead wire from falling off. The clamping side of the clamping plate 2 has serrated lines. It is used to increase the friction force and prevent the copper-aluminum equipment wire clamp from falling off.
