Description

Technical Field

[0001] This utility model relates to the field of high-voltage power transmission technology, and in particular to a compression conductor node shunt fitting. Background Technology

[0002] Currently, most high-voltage line tension towers typically have a tension clamp crimped to the end of the high-voltage line on both the front and rear sides of the tower. The two tension clamps are connected by a jumper wire with shunt clamps at both ends, secured with bolts, to transmit electrical energy. However, because bolted connections are prone to loosening during operation, overheating often occurs. Therefore, an external parallel connection is needed to short-circuit the bolt lock by connecting the high-voltage line and the shunt wire separately to solve the overheating problem. However, existing parallel connections are also bolt-lock structures, so overheating still occurs after a period of use. For some important lines that require uninterrupted power for extended periods, this constant repairs waste a significant amount of manpower.

[0003] Chinese patent CN218569241U discloses a hydraulic connector current-carrying reinforcement fitting and its connection structure, which solves the problem of existing bolted high-voltage line nodes easily overheating and requiring constant repairs. Furthermore, it allows for live installation on operating lines without power outages. However, this fitting has a problem with poor waterproofing at the arc-shaped sliding plate and through-hole joint. Utility Model Content

[0005] This utility model is implemented using the following solution: a compression-type conductor node shunt fitting includes a bent tube body, the bent tube body including a crimping tube part and a connecting tube part connected together by an arc-shaped tube part, the crimping tube part is provided with a wire passage with one end penetrating the arc-shaped tube part and the other end penetrating the end of the crimping tube part, the upper side of the wire passage is provided with a slot penetrating the top of the crimping tube part and the arc-shaped tube part, the slot is provided with a cover plate covering the wire passage, and the cover plate is provided with sealing channels on both sides.

[0006] Furthermore, the slot is divided into two sections along its length: a constant-width section at the arc-shaped tube section and a variable-width section at the press-fit tube section. The cross-section of the variable-width section of the slot is dovetail-shaped, wider at the top and narrower at the bottom. The length of the cover plate is the same as the length of the press-fit tube section and it can be slidably installed in the variable-width section of the slot.

[0007] Furthermore, the cover plate has inclined surfaces on both sides that are adapted to the widening section of the slot, and the bottom of the inclined surfaces on both sides of the widening section of the slot is provided with support steps for supporting the cover plate.

[0008] Furthermore, the slot forms a limiting step surface that abuts against the end of the cover plate at the transition between the equal width section and the variable width section.

Detailed Implementation

[0021] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0023] like Figures 1-6 As shown, a compression-type conductor node shunt fitting includes a bent tube body 100. The bent tube body 100 includes a crimping tube section 110 and a connecting tube section 130 connected together by an arc-shaped tube section 120. The included angle between the crimping tube section 110 and the connecting tube section 130 is an obtuse angle. A wire-passing channel 140 is provided inside the crimping tube section, with one end penetrating the arc-shaped tube section and the other end penetrating the end of the crimping tube section. A slot 150 is provided on the upper side of the wire-passing channel, penetrating the top of the crimping tube section and the arc-shaped tube section. The wire-passing channel 140 and the slot 150 are connected. A cover plate 200 is provided inside the slot, covering the wire-passing channel. Sealing channels 210 are provided on both sides of the cover plate. The high-voltage wire is inserted through the slot 150, then sealed with the cover plate 200, and finally tightened by external hydraulic equipment to achieve a secure connection. This avoids oxidation or poor contact in bolt connections, thus minimizing the possibility of overheating. Furthermore, it allows for live installation on existing lines without power interruption, facilitating the maintenance of critical lines requiring continuous power. Additionally, sealing channels 210 are provided on both sides of the cover plate. When the crimping pipe section 110 is tightened by the hydraulic equipment, its deformation generates ribs 111 that are squeezed into the sealing channels 210. The ribs fit tightly against the sealing channels 210. Figure 4As shown, this can improve the sealing performance of the joint and enhance the waterproofing effect; after the compression fitting 110 and the cover plate 200 are deformed by the hydraulic equipment, their cross-sectional shapes change, which can be polygonal or other shapes, depending on the structure of the fixture on the hydraulic equipment.

[0024] In this embodiment, the slot 150 is divided into two sections in the length direction: a constant width section 151 located at the arc-shaped tube section and a variable width section 152 located at the crimping tube section. The cross-section of the variable width section of the slot is a dovetail shape that is wider at the top and narrower at the bottom. The length of the cover plate is the same as the length of the crimping tube section and it can be slidably installed in the variable width section of the slot. The dovetail structure not only enables the cover plate to slide axially, but also prevents the cover plate from slipping radially.

[0025] In this embodiment, the two sides of the cover plate 200 are inclined surfaces adapted to the two sides of the widening section of the slot, and the bottom of the inclined surfaces on both sides of the widening section 152 of the slot 150 is provided with a support step surface 153 for supporting the cover plate.

[0026] In this embodiment, the slot forms a limiting step 154 ​​at the transition between the equal width section and the variable width section, which abuts against the end of the cover plate. When the cover plate is installed, it slides into the slot from one end, and slides into place when the cover plate touches the limiting step 154.

[0027] In this embodiment, the cover plate 200 has an arc-shaped cross-section. The radius of the outer arc surface of the cover plate is the same as the radius of the outer peripheral wall of the crimping pipe, and the radius of the inner arc surface of the cover plate is the same as the radius of the inner peripheral wall of the crimping pipe. The cover plate and the crimping pipe with the slotted opening form a complete tubular structure.

[0028] In this embodiment, a wiring channel 160 is provided inside the wiring tube 130, which passes through the lower end of the wiring tube. A sealing plate 170 is provided inside the arc-shaped tube to block the upper end of the wiring channel. The drain wire is inserted into the wiring channel 160, and then the wiring tube 130 is pressed by an external hydraulic device to make the drain wire and the wiring tube firmly connected.

[0029] In this embodiment, the sealing channel has an arc-shaped cross-section and is arranged along the length of the cover plate and extends to both ends of the cover plate.
