Quick-installed electric transmission line diagnostic terminal

Abstract

The invention discloses a quick-installed electric transmission line diagnostic terminal. The quick-installed electric transmission line diagnostic terminal is divided into two parts which are an upper cover and a box body, and the upper cover is connected with the box body by one side through a double-shaft hinge; a hoop assembly on the upper cover comprises a hoop fastening bolt and a hoop; a limiting groove is formed in the upper cover, and a pressing spring presses the hoop in the limiting groove; an outwardly extending boss is arranged at one end of the hoop, and a limiting protrusion block is fixedly arranged on the box body; when the hoop rotates with the upper cover, the boss on the hoop can be buckled on the limiting protrusion block on the box body; and when installing on an overhead line is carried out, the upper cover is rotated to open at a certain angle and to be placed on a wire, the hoop fastening bolt is rotated into a hoop fastening nut on the box body, and the uppercover and the box body are fixed to the overhead line. The quick-installed electric transmission line diagnostic terminal adopts the fastening hoop bolt to realize the installation and fixation on theoverhead line, fasteners are not separately installed, the phenomenon that parts drop does not occur, the installation and disassembly operation of the terminals on the overhead line is simplified, and installation and maintenance are convenient.

Description

Technical field [0001] The invention belongs to the technical field of power transmission line monitoring, and relates to a power transmission line diagnostic terminal. Background technique [0002] The power transmission line diagnostic terminal usually adopts the upper and lower split form. The upper cover and the lower box are installed and locked and then wrapped on the transmission line. The power is taken on the transmission line through the energy extraction CT to monitor the line operation status. The power transmission line diagnostic terminal is composed of electrical units such as energy acquisition, measurement, data processing, and wireless signal transmission. When the terminal is installed, the upper and lower parts of the energy-taking coil and the magnetizer need to be aligned, locked and fixed, the measuring coil needs to be closed and locked, the box body and the overhead wire need to be equipotentially connected, and the upper cover and the box body need to be...

AI Technical Summary

Problems solved by technology

These components are separated, and there are many scattered parts, which makes it difficult to install the terminal on the overhead line

If fasteners or installation tools fall during the installation process, they need to be retrieved and reinstalled. The installation workload will be doubled and the installation terminal on the overhead line will increase.
