Embodiment Construction

[0025] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0026] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes ...

Abstract

The invention relates to a needle-type plug structure, which includes a conductive body that can be inserted into a terminal hole of a substation secondary equipment, a clamping component and a conductive adsorption piece. The side wall of the conductive body is provided with a receiving through groove. The clamping component includes a ball accommodated in the receiving groove and an elastic member accommodated in the receiving groove. Part of the balls protrude from the receiving slot. One end of the elastic member is connected with the ball in transmission, and provides an elastic restoring force for the ball to drive the ball to move away from the conductive body. The conductive absorbing part is fixed on the end of one end of the conductive body. The conductive absorbing part is used to provide an absorbing force for the inner conductor in the terminal hole. The setting of clamping components and conductive adsorption parts can ensure the clamping effect of the pin-type plug structure and the terminal hole and the inner conductor without the need for the operator to hold the pin-type plug structure for a long time during the test of the secondary equipment of the substation. The reliable contact between them greatly reduces the risk of on-site operation when testing the secondary equipment of the substation.

Description

technical field [0001] The invention relates to the technical field of substation equipment, in particular to a needle-type plug structure. Background technique [0002] In order to ensure the safe and stable operation of the power grid, it is necessary to regularly carry out regular inspections, experiments, and elimination of primary and secondary equipment in the substation. At this time, it is necessary to extract the secondary voltage signal of the equipment. For example, when carrying out live detection of 110kV arrester, it is necessary to extract the voltage signal on the secondary side of the voltage transformer of the corresponding 110kV bus as a reference for detecting the power loss, leakage current and impedance angle of the arrester. [0003] However, in the process of extracting the secondary voltage signal, because the hole diameter of the secondary terminal row of the substation HSBC panel is too small and the depth is large, it is very easy for the terminal...
