Description
Technical field
The present invention relates to a kind of power cable splicing fittings more particularly to a kind of power transmission line DC ice melting of Fast Installation to fill
It sets.
Background technique
Current ice-melt operation be mostly by the way of direct current be shorted ice-melt, need staff will be shorted cable sling into
The installation of row high-altitude requires more careful, workload to the wiring in high-altitude because having the requirement of ice-melt high current and conduction time
Greatly, need to fill, tear open the connection of Stranded cable connector and high-tension line.In order to reduce power off time, new regulatory requirements subtract as far as possible
Few ice-melt time (ice-melt operates overall time control within 4 hours), and use the retractable of current technology short-circuiting cable
It is more time-consuming with fixation, staff is easy to happen fatigue, and in addition working environment general summer coolness is wet and slippery, working time length and peace
Full property is also inversely proportional.Winter, largely a large amount of ice-melt operations caused by existing high-voltage line icing phenomenon will seriously affect work at present
Industry safety.Therefore, the exploitation of the design and novel ice-melt fitting that carry out novel ice-melt scheme has important practical value, can be with
A large amount of manpower, material resources and financial resources spent by the progress line ice-melting operation for solving to be widely present are reduced, are improved in harsh weather
Under operational security, operation quality and efficiency solve the relative complex high-altitude application of original dependence and limited operation means
Insoluble de-icing technology problem.It carries out turning spiral shell in the case where needing to raise high in device on traditional short-circuit device
Silk or nut, generally require two people and operate, even if people's operation is also to need to expend the biggish mind and physical strength,
This has just met the reason of " working time is longer, and safety is poorer " of above-mentioned background description, considers toward other situations, electric power dimension
Nurse people not just dismantles or installs one, in multiple installations, disassembly, will be finished strength quickly and carry out rotation,
From this point on for very unfavorable on teams and groups' working efficiency and labor intensity.It is considered based on the above actual conditions, had been badly in need of one kind both
Energy Fast Installation can save the mounting device of physical strength again.
Summary of the invention
Poor, installing and dismounting large labor intensity that present invention mainly solves safeties, time-consuming problem more, working efficiency is slow,
Provide it is a kind of it is highly-safe, pull intensity it is low, it is time-consuming less, a kind of power transmission line DC ice melting for Fast Installation that work efficiency is high
