Embodiment 1
[0019] This embodiment is an improved electric power fitting for overhead lines, see Figure 1 to Figure 5 As shown, it includes a base tube 1, a core tube 2, two sets of pressing jaw assemblies 3 and two flat nuts 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 each crimping The inner wall of the boss is provided with an arc-shaped groove 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 core tube and the base tube are arranged concentrically and are located in the lumen of the base tube; The wall is provided with a plurality of supporting convex plates 21 protruding and extending radially along the core tube, and the outer end of each supporting convex plate is located in a corresponding positioning chute, so that the core tube is supported and positioned in the lumen of...
Embodiment 2
[0031] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 6 and Figure 7 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.
[0032] 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.
[0033] 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
[0041] This embodiment is basically the same as Embodiment 2, the difference is: see Figure 8 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.
[0042] The inner peripheral wall of the intelligent control module 92 is provided with two sockets protruding inwards (not shown on 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
[0043] 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 cab...
