The tower is provided with a wireless switch, according to weather conditions of different areas of a circuit, the wireless switch can be controlled through a wireless controller, and working states of the heating layers between two optional towers can be controlled, thereby not only deicing in time but saving energy.
Description
Technical field
The utility model belongs to field of electrical equipment, is specifically related to a kind of line de-icing system.
Background technology
Along with high speed development of national economy, all trades and professions are increasing to the demand of electric power, requirement is also more and more higher, so the fail safe of the operation of power networks of long distance power transformation circuit seems particularly important to provide the quality (stability, continuous and follow service) of supply of electric power to power supply department.The residing geographical environment of long distance power transformation circuit, weather conditions are more abominable, particularly in the winter time, because of temperature lower, humidity is higher, has icing on the cable for a long time, and along with the reduction and the prolongation of low temperature time of temperature, the thickness of icing is increasing, the weight load of bringing to high-voltage conducting wires is increasing thus, when the total weight of icing surpasses the strength degree of cable, and the serious consequence that can cause disconnected cable even pylon to collapse.China by icing cause fall tower, wave, ice the sudden strain of a muscle accident and frequently take place, caused enormous economic loss and casualties.Domestic power industry every year, the reason because of icing caused the accident of disconnected cable to happen occasionally, disconnected cable bring directly, indirect economic loss reaches billions of RMB, effective deicer is being sought for this reason always by each Utilities Electric Co..Existing deicing measure is the accumulated ice on cable when reaching certain thickness, artificially controls the ice removal deicing, be as described in " CN101202430A ", the utility model patent that is called " remote-control electrodynamic mechanical type line de-icing system " as publication number.This device needs the thickness that the people monitors ice sheet on the cable constantly, handles accumulated ice timely.And cable is aerial at height, and monitoring is got up cumbersome, consequently can not remove the icing on the cable timely.
The utility model content
To be solved in the utility model is the problem of existing overhead power line deicing in time, and a kind of line de-icing system that can in time remove icing in the circuit is provided.
The technical solution of the utility model realizes with following method:
A kind of line de-icing system comprises transformer station, pylon and is arranged on cable on the pylon, and described cable is the heating deicing cable; Described heating deicing cable is that insulating barrier coats heat insulation layer outward at cable core outsourcing insulating layer coating, and heat insulation layer coats heating layer outward, and heating layer connects power supply and mains switch is set.
Described power supply and mains switch are arranged in the transformer station.
On the described pylon wireless switching is set, wireless switching connects heating layer and heating layer supply lines
The utility model is simple in structure, covers to wrap up in one deck heating layer outside the insulating barrier of cable, and heating layer links to each other with the power supply of setting in the transformer station, and the operating state of heating layer is controlled by mains switch.In the environment that freezes, the power-on switch, heating layer is started working, and distribute heat in time melts the ice and snow that drops on the circuit; In not having icing environment, the powered-down switch, heating layer quits work.Wireless switching is set on pylon, according to the weather condition of circuit zones of different section, controls wireless switching on ground by wireless controller, can control the operating state of the heating layer between any two pylons, deicing in time can be saved the energy again.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the schematic diagram of heating deicing cable in the utility model.
Embodiment
As depicted in figs. 1 and 2, the utility model comprises transformer station 5, pylon 7 and is arranged on cable on the pylon 7.Described cable is a heating deicing cable 6; Described heating deicing cable 6 is at cable core 1 outsourcing insulating layer coating 2, the insulating barrier 2 outer heat insulation layers 3 that coat, and the heat insulation layer 3 outer heating layers 4 that coat, heating layer 4 connects power supply and mains switch is set.Described power supply and mains switch are arranged in the transformer station 5.
On the described pylon 7 wireless switching 8 is set, wireless switching 8 connects heating layer 4 and heating layer supply lines.The voltage setting of described heating layer supply lines and the running parameter of heating layer coupling.
The utility model course of work is as follows: in the environment that freezes, and energized, the power-on switch, heating layer 4 is started working, and removes the ice and snow of heating deicing cable 6 outer surfaces.In the practical operation,, by the wireless switching 8 on the wireless controller remote control pylon 7 that is provided with on the ground, can allow the heating layer work of part cold area, and the heating layer in relatively-high temperature district quits work according to the warm and humid environment of circuit zones of different.
