Embodiment 1)
[0017] This embodiment is an improved high-voltage current transformer, see Figure 1 to Figure 6 As shown, it includes a base pipe 1 , a core pipe 2 , two sets of pressing jaw assemblies 3 , two flat nuts 4 and a current transformer 9 .
[0018] The inner peripheral wall of the base pipe is provided with three crimping bosses 11 along the axial direction of the base pipe, and the inner wall of each crimping boss is provided with an arc-shaped groove 111; the inner peripheral wall of the base pipe is also provided with four positioning slides along the axial direction of the substrate Slot 12; the core tube and the base tube are concentrically arranged and located in the base tube lumen; the outer peripheral wall of the core tube is provided with four supporting convex plates 21 protruding radially along the core tube, and the outer ends of each supporting convex plate are located at corresponding to a positioning chute, so that the core tube is supported and positioned in the...
Embodiment 2)
[0029] 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 fixedly installed in the mounting screw hole.
[0030] 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.
[0031] 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 internal thread area 817 is provided on the inner peripheral wall of the accommodating groove; the ...
