Embodiment 1）

[0020] The present embodiment is a power line clamp for overhead lines, see Figure 1 to Figure 8 as shown,

[0021] It includes a base tube 1, a core tube 2, a set of pressure jaw assembly 3 and a flat nut 4; the inner peripheral wall of the base tube is provided with a plurality of crimping bosses 11 along the axial direction of the base tube, and the inner wall of each crimping boss There are arc-shaped grooves 111; the inner peripheral wall of the base tube is also provided with a plurality of positioning slide grooves 12 along the axial direction of the base tube; the outer peripheral wall of the core tube is provided with a plurality of supporting convex plates 21 protruding and extending radially along the base tube , the outer end of each support convex plate is located in a corresponding positioning chute, so that the core tube is supported and positioned in the lumen of the base tube; the core tube and the base tube are concentrically arranged and located in the lume...

Embodiment 2）

[0033] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 9 and Figure 10 As shown, the base pipe 1 is provided with a mounting screw hole 15 radially penetrating through the wall of the base pipe; a temperature sensing device 8 is fixed in the mounting screw hole.

[0034] 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 tube plug 84 that is used for limit spring.

[0035]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 is an external thread 816 adapted to the mounting screw hole, and an...

Embodiment 3）

[0043] This embodiment is basically the same as Embodiment 2, the difference is: see Figure 11 As shown, a current transformer 9 is sleeved and fixed on the outer peripheral wall of the base pipe 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 induction The main body 91 and the intelligent control module 92 are arranged side by side.

[0044] When the number of crimping bosses and pressing claws in this embodiment is three, this embodiment can form three clamping holes for clamping three phase cables. At this time, this embodiment as a whole can be used as a high-voltage zero Sequence current transformers are used to detect the existence of leakage currents and discover leakage faults in time.

[0045] The inner peripheral wall of the intelligent control module 92 is provided with two sockets protruding inwa...

Abstract

The invention discloses a power line clamp for an overhead line. The power line clamp comprises a base tube, a core tube, a set of pressing claw assembly and a plane nut, wherein the inner circumferential wall of the base tube is equipped with a pressing boss, a radial limiting slide hole is formed in the tube wall of the core tube, and the inner circumferential wall of the core tube is equipped with an annular blocking table; the pressing claw assembly comprises multiple pressing claws, and each pressing claw comprises a pressing plate part, a guide slide block part and a driving threaded part; the plane nut is disposed in the tube chamber of the core tube in a rotatable manner; the plane nut comprises a plane threaded part which is meshed and fit with the driving threaded part of each pressing claw; and an installation screw hole equipped with a built-in temperature sensing device is formed in the base tube. The power line clamp disclosed by the invention can effectively prevent loosening.

Description

technical field [0001] The invention belongs to the technical field of power fittings for overhead lines, and in particular relates to a power line clamp for overhead 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 conductors together with power line clamps for overhead lines. Power line clamps for overhead lines have 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; using insulated overhead lines and power line clamps as cable branches, the comprehensi...
