background technology
In transmission of electricity safety protection technique field, prevent that powerline ice-covering technology from being the important leverage of Transmission Line in Winter safe and stable operation, is directly connected to power grid security and power supply reliability.Meet between the kurtosis teletostage and affected by low temperature sleety weather at electrical network, " microclimate district " or other regions of transmission line, because forming, rime, glaze cause power line conductive, ground wire icing backarc to hang down and fall, cause ground wire and conductor spacing deficiency, cause after wire is to ground wire electric discharge, wire icing that phase spacing deficiency causes line tripping.The similar trip-out rate that relates to ice fault rises year by year, and Transmission Line in Winter safety and reliability is constituted a serious threat.For preventing that transmission line from relating to the generation of ice fault, power grid maintenance department is the manpower and materials of the amount of having high input all the year round, and anti-icing equipment is installed on transmission line, due to comprehensive not to Transmission Line in Winter icing understanding, make the specific aim of anti-icing work and validity not strong.Therefore, be necessary conscientiously to study for the icing type, the de-icing method that affect transmission line safety, well-designed to deicer, to improve the scientific and effective of grid power transmission circuit control ice and snow disaster work.
At present, transmission line remove the method for icing have a variety of, but simply, effectively few.Conventional method has heating ice-melting method, its deicing principle is to make transmission line stream super-high-current, by the heating up thawing icing of line resistance, but this method must first be carried out power down process to transmission line, then the straight line current that applies large electric current at icing section circuit, by the resistance heating on Xian Tiao road itself, now changes icing, this method needs could operate after power-off, often affects line work.Used in addition the method for artificial removal's powerline ice-covering in the past, found through observing that deicing effect was bad, efficiency is not high, be sometimes difficult to carry out.
summary of the invention
The purpose of this utility model is the generation in order effectively to prevent powerline ice-covering, ensures transmission line safe operation in winter, and the utility model discloses a kind of device of removing powerline ice-covering.
Realizing the technical scheme that the utility model adopts is: the device that the utility model is removed powerline ice-covering is made up of linear electric motors, deicer, and the spiral plow-shape deicing head being made up of symmetrical halves is fixed on respectively the linear electric motors body two ends that are made up of two semi-annular shape linear electric motors bodies.
The linear electric motors body that described linear electric motors are semi-annular shape by two identical cross sections forms, and the linear electric motors body of described semi-annular shape includes coil, iron core, lithium battery and control circuit board, semicircle shell seal cover, for holding the center semicircle orifice of wire; Coil embeds in iron core slot, and lithium battery and control circuit board are arranged on outside iron core, all parts of semicircle shell seal cover ladle cover linear electric motors body; The linear electric motors body of two semi-annular shapes is combined and forms a tube type linear electric motors, and center forms circular hole by two interior semicircle orifices and holds wire and pass.Semicircle shell seal shroud rim is provided with the circular hole of construction bolt, in the time that the linear electric motors body of two semi-annular shapes is combined, is tightened up by bolt.
In the time that needs carry out deicing to wire icing, the linear electric motors body of two semi-annular shapes is clipped in to the not yet conducting line segment of icing, the linear electric motors of two semi-annular shapes are tightened up with bolt, start linear electric motors with remote controller on the ground; Linear electric motors are on wire when moving linearly, and the spiral plow-shape deicing head of linear electric motors front end can be removed rime on transmission line, glaze and icing at traveling process.Linear electric motors, by the lithium battery power supply being arranged on linear electric motors, adopt remote controller to command control by operating personnel on the ground.
Operation principle of the present utility model is, linear electric motors body is the movement parts of deicer as the elementary of linear electric motors, and secondary is the cable wire at wire center; The steel core of the magneticaction that the coil of linear electric motor primary produces in transmission line produces actuating force, and linear electric motors are moved along wire direction on wire, is used for promoting deicer and advances.
The beneficial effects of the utility model are that the utility model adopts and on wire, removes icing with the linear electric motors of spiral plow-shape deicing head, installs simply applicable.The linear electric motors of deicer provide power supply by high-performance lithium battery, and lithium battery is rechargeable battery, therefore install reusablely, and installation method is simple, rapidly.Deicing effect is remarkable.
The utility model is applicable to power line lead and removes icing.
