Hitching device for ice melting cable

Abstract

The invention provides a hitching device for an ice melting cable. The hitching device comprises a connection part and is characterized in that a double-tongue hook, an ice melting wire and an insulation rod are connected to the connection part; the double-tongue hook is fixedly connected to the connection part through a bolt; and the insulation rod is arranged between two hooks of the double-tongue hook. The beneficial effects of the hitching device are that by use of the hitching device, people can perform electricity verification, short circuit connection and cable connection without climbing to the rod; people can easily finish above work by standing on the ground; and the test shows that the work time is only 12 minutes and the number of the operators is reduced to 6 from 12. Thus, manpower is effectively reduced; ice melting time is greatly reduced; a risk of falling off from the high place when a worker climbs to the rod under the freezing weather can be effectively avoided; and the hitching device is advantaged by simple structure, low cost and remarkable effects.

Description

technical field [0001] The invention relates to the technical field of electric power system power supply, in particular to an ice-melting cable hooking device suitable for high-voltage cables. Background technique [0002] With the change of the earth's environment, extreme climates appear more and more frequently, especially the large-scale freezing in southern cities in my country in 2008, which caused large-scale power outages in the power grid and then caused the collapse of the power grid. Therefore, in recent years, various ice-melting cables and other various ice-melting measures have emerged as the times require. It is common to use direct current to melt ice on 500KV circuits, and for 35KV and 10KV lines, usually use ice-melting transformers to conduct three-phase AC on the lines. Short circuit ice melting method. [0003] The invention patent with the application number 200820037792.X discloses an ice-melting cable. The cable includes a main cable composed of a c...

Problems solved by technology

The structure of the cable is simple. It only needs to heat up the temperature of the assembly line, and then heat the cable to achieve the purpose of deicing and melting. During the ice melting process, the staff need to board the pole first to confirm that there is no voltage, and then set up closed short-circuit grounding wires at both ends of the working area, and then the staff can install the ice-melting short-circuit line or ice-melting cable on the pole. The specific operation is more cumbersome
