Embodiment 1）

[0018] This embodiment is a kind of splicing clamp for power transmission and distribution lines, see Figure 1 to Figure 6 As shown, it includes a core tube 2, a set of pressing jaw assembly 3, a flat nut 4 and three crimping parts 1.

[0019] The tube wall of the core tube is provided with three radial limiting sliding holes 22, and each radial limiting sliding hole runs through the core tube tube wall along the radial direction of the core tube; each radial limiting sliding hole is located on the axial direction of the core tube. In the middle part, the radial cross-sectional shape of each radial limit hole is I-shaped; the inner peripheral wall of the core tube is provided with an inwardly protruding annular stopper 23 .

[0020] Each crimping piece is provided with a pressing plate portion 11 and an anti-off connecting portion 12; the crimping piece is detachably arranged on the core tube through the anti-off connecting portion; the pressing plate portion 11 extends axial...

Embodiment 2）

[0034] This embodiment is basically the same as the above-mentioned embodiment 1, the difference is that: see Figure 7 and Figure 8 As shown, at least one crimping piece 1 is provided with a mounting screw hole 15 penetrating through the pressing plate part in the radial direction of the core tube; a temperature sensing device 8 is fixed in the mounting screw hole.

[0035] The temperature sensing device 8 includes a metal housing 81 made of metal material with a containing groove 811, a temperature sensor 82 arranged in the containing groove, and a spring 83 for crimping the temperature sensor on the bottom wall of the containing groove , The screw pipe plug 84 that is used for limit spring.

[0036] One end 812 of the metal shell close to the central axis of the core tube is provided with a heat conduction boss 813 used as a puncture, and one end 814 of the metal shell away from the central axis of the core tube is provided with an inner hexagonal screw groove 815; There i...

Embodiment 3）

[0044] This embodiment is basically the same as the above-mentioned embodiment 2, the difference is: see Figure 9 As shown, a current transformer 9 is sleeved and fixed on the outer peripheral wall of the crimping piece in this embodiment, and the current transformer 9 includes a ring-shaped induction body 91 and an intelligent control module 92; the overall shape of the intelligent control module is also ring-shaped; the ring-shaped The sensing body 91 and the intelligent control module 92 are arranged side by side.

[0045] The inner peripheral wall of the intelligent control module 92 is provided with two sockets protruding inward (not shown in the figure), and each socket is inserted into a corresponding socket, so that the temperature sensor and the intelligent control module connected to the central control circuit in the

[0046] This embodiment can be used to clamp three phase cables. At this time, this embodiment as a whole can be used as a high-voltage zero-sequenc...

The invention has the function of real-time temperature monitoring.

Description

technical field [0001] The invention belongs to the technical field of electric power fittings for overhead lines, and in particular relates to a splicing clamp for power transmission and distribution lines. Background technique [0002] In the construction of overhead power lines, when the cables need to be branched or spliced, it is necessary to connect two insulated wires together with splicing clamps for power transmission and distribution lines. The splicing clamp for power transmission and distribution lines has the characteristics of easy installation, low cost, safety, reliability and maintenance-free. Cable branches can be made without cutting off the main cable or stripping the insulation layer of the cable. The joints are completely insulated and can be used for live work, and can be branched at any position on the cable; no terminal box or junction box is needed; and the joints are resistant to twisting, Shockproof, waterproof, anti-corrosion and aging; use sp...
