Abstract

The utility model relates to the installation of a protective ground wire when processing power-off check of the high voltage line, belonging to the electric power industry in particular to an adaptor of the protective ground wire. Based on mechanical principle, the adaptor of the protective ground wire of the utility model can be installed by one operator, ensuring less labor and time. The structure of the utility model is demonstrated in the illustration. The utility model comprises a line hook (1), a pressing line plate (2), a connection terminal (3) and a handlebar (4). The pressing line plate is fixed on the line hook by the guide way and the pressing line plate is enabled to move in the line hook when the handlebar is rotated. The connection terminal is led out from the pressing line plate and the upper half part of the line hook is not straight but inclined downwards when seen from the lateral side.

Description

Protection ground wire electric wire connecting junction

The utility model relates to power industry high pressure grade line outage maintenance the protection ground wire is installed, and the electric wire connecting junction that the protection ground wire is used particularly is installed.

When the line outage of power industry high pressure grade is overhauled, the protection ground wire must be installed on dead line, send electricity to prevent accident, cause human casualty accident.

The electric wire connecting junction of protection ground wire was installed on dead line in the past, bothersome effort was installed.For this reason, designed the utility model.

Fig. 1 is the utility model structure chart.Among the figure: [1] is that the line hook, [2] that are used for hanging on the circuit are that tension disc, [3] that are used for circuit is compressed on the online hook are to be used for the binding post that is connected with ground wire, the joystick that [4] move tension disc.Tension disc is contained on the slideway of line hook, and the leading screw on the joystick is spun on the screw of line hook, and joystick connects with tension disc is movable, swivel lever, and tension disc advances, and tension disc compresses lead on the online hook.

Fig. 2 is the utility model structure side view.From end view as seen, the first half of line hook is reclinate.

Practical operation proves, uses the utility model protection ground wire electric wire connecting junction, and the set-up time is 1/5th of an old-fashioned electric wire connecting junction, has saved the valuable interruption maintenance time.

Claims

1. one kind is used for the electric wire connecting junction that the protection ground wire is installed in power industry high pressure grade line outage maintenance; it is characterized in that: by being used for hanging over line hook [1] on the circuit, circuit being compressed tension disc [2] on the online hook, is used for the binding post [3] that is connected with ground wire, the joystick [4] that tension disc is moved and forms; tension disc is contained on the slideway of line hook; leading screw on the joystick is spun on the screw of line hook; joystick connects with tension disc is movable; swivel lever; tension disc advances, and tension disc compresses lead on the online hook.
