specific Embodiment approach 1

[0009] Specific implementation mode one: combine Figure 1 to Figure 3 Note that the fixing device in this embodiment includes a conductive rod 1-0, a magnet 1-1, a hook 1-2, two arc-shaped support pieces 2-0 and at least four springs 3-0,

[0010] The magnet 1-1 is fixed on one end of the conductive rod 1-0, the crotch 1-2 is fixed on the other end of the conductive rod 1-0, the concave arc surfaces of the two arc-shaped supporting pieces 2-0 are arranged oppositely, and the conductive rod 1-0 0 is vertically arranged between two arc-shaped support pieces 2-0, and the concave arc surface of each arc-shaped support piece 2-0 and the side wall of the conductive rod 1-0 are fixed by at least two springs 3-0 To connect, an arc-shaped boss 2-1 is affixed to the one end of the convex arc surface of the arc-shaped support piece 2-0 close to the conductive rod 1-0.

specific Embodiment approach 2

[0011] Specific implementation mode two: combination Figure 1 to Figure 3 Explain that the number of the springs 3-0 in this embodiment is eight, and four springs 3-0 form a group, and one end of each group of springs 3-0 is connected with the concave arc surface of an arc support piece 2-0 respectively. The four corners of the springs 3-0 are affixed to each other, and the other ends of the set of springs 3-0 are respectively affixed to the side walls of the conductive rod 1-0.

[0012] The eight springs 3-0 increase the supporting force of the two arc-shaped support pieces 2-0 on the inner wall of the secondary terminal port, making the fixing of the connection and fixing device of the present invention more reliable and meeting the needs of use.

Abstract

The invention relates to a device for being connecting with a high-voltage mutual inductor secondary terminal port ground lead, in particular to a fixing device for being connecting with the high-voltage mutual inductor secondary terminal port ground lead. The fixing device aims to solve the problem that in the prior art, a device which is small in size and capable of enabling the ground lead to be firmly fixed on a secondary terminal port does not exist. A magnet is fixed at one end of a conducting rod, a hook is fixed at the other end of the conducting rod, concave arc faces of two arc supporting pieces are opposite, the conducting rod is vertically arranged between the two arc supporting pieces, the concave arc face of each arc supporting piece and the side wall of the conducting rod are fixed connected through at least two springs, and an arc boss is fixedly connected to the end, close to the conducting rod, of the convex arc face of each arc supporting piece. The fixing device is used for being fixedly connected with the high-voltage mutual inductor secondary terminal port ground lead.

Description

technical field [0001] The invention relates to a device for connecting the ground wire of a secondary terminal port of a high-voltage transformer. Background technique [0002] In the process of debugging the high-voltage transformer, it is necessary to ground the secondary terminal port of the high-voltage transformer for debugging, but because the secondary terminal port is smaller than the fingernail of an adult's little finger, it is very inconvenient to ground the secondary terminal port. There are two existing technologies. One is to remove the screw in the secondary terminal port, wrap the ground wire on the outer wall of the screw, and then install the screw into the secondary terminal port. This method not only cannot ensure that the ground wire is entangled Strong, the grounding wire is easy to fall off during the debugging of the high-voltage transformer, and it is not easy to find. When the high-voltage transformer is grounded for debugging, the high-voltage tra...
