Line melts the icing on its surface using the fuel factor of electric current.Wherein melt for the ground wire of ± 800kV UHV Transmission Engineering development
Ice automatic connection device is by cage jumper electricity getting device, split type folding conductor, transmission mechanism, protective cover and electric control system
It constitutes.
Cage jumper electricity getting device of the invention, several wire clamp collets hold with a firm grip wire jumper sub-conductor obtain electric current, electricity getting device line
Folder straddles the top of hard jump steel pipe, is not only simple in structure, also achieves the direct transition of electric current；Overcurrent one end of the connection board with
Electricity getting device wire clamp is fixedly connected with acquisition electric current, and the other end is connect with contact finger structure makes electric current smoothly reach fingertip component；Overcurrent connects
Fishplate bar one end is connect with electricity getting device wire clamp, and the other end is welded on fingertip component, overcurrent connecting plate and electricity getting device wire clamp connecting side
Contact surface be both needed to be machined to meet overcurrent requirement, and punch it is several, in addition to guaranteeing connection requirement, in order to the progress of fingertip component
The adjusting of vertical direction size, has also been devised the adjusting mounting hole of vertical direction, and overcurrent connecting plate and the connection of fingertip component are adopted
With welding pattern, structure is simple and direct, while meeting through-flow requirement, and the part for protruding wire jumper uses orthodrome transition, while outer
It encloses and has carried out corona preventing construction design.
Shield is mounted on fingertip component, and guide plate, fingertip component are covered completely into wherein, sleet and snow ice is avoided to invade
It attacks, meanwhile, side uses movable door structure, both can further protect, and nor affect on the realization of closing function.Shield installation
In guide plate and fingertip periphery, top uses domes, is conducive to sleet and slides；Figure of eight structure is used along guide plate direction,
Simplify its outer dimension；Guide plate opening uses movable overhead door, is pushed into when combined floodgate and opens with contact, with touching when opening a sluice gate
Head disengaging and fall.Shield is directly installed on contact finger structure.
Connection shroud ring is mounted on the steel pipe of squirrel-cage wire jumper, and is connected and fixed with electricity getting device wire clamp, guarantees that electricity getting device exists
Fixation on wire jumper.Connection shroud ring will not only bear the own wt of cage jumper electricity getting device and remain steady, also undertake conjunction
The high torque that lock power generates cage jumper electricity getting device guarantees stability of the cage jumper electricity getting device on wire jumper.Connection packet
After several uniformly distributed hangers and electricity getting device wire clamp of hoop are connected and fixed, then it is installed on the steel pipe of squirrel-cage wire jumper and is consolidated
It is fixed.
When the present invention installs, the determination of position is carried out according to the other component position of ground wire deicing automatic connection device.
Firstly, by the electricity getting device without connection shroud ring horizontal through being straddled vertically again after conducting wire above steel pipe, according to live driver
The position of structure selects suitable position on conducting wire, and conducting wire is packed into wire clamp.Then, according to the combined floodgate situation pair of contact, fingertip
Cage jumper electricity getting device, transmission mechanism position be finely adjusted, until contact can be aligned fingertip center complete close a floodgate.Electricity getting device
After wire clamp positioning, each wire clamp collet is held with a firm grip each sub-conductor of wire jumper, then installation connection shroud ring.Connect the hangers and electricity getting device of shroud ring
It is connected and fixed by fastener, and connection shroud ring is fixed on the steel pipe of the hard wire jumper of squirrel-cage.Since connection shroud ring is not only wanted
Cage jumper electricity getting device self gravity and torque can be born, the torque generated when still suffering from combined floodgate, so to guarantee connection packet
Hoop must not be loosened or be rotated on steel pipe.
Since the hard wire jumper of squirrel-cage has deviation to cross-arm distance and Theoretical Design, so overcurrent connecting plate is designed to independence
It is adjustable, selection is adjusted when scene opens and closes conductor length adjustment deficiency.If exceeding adjustable range, one piece can be passed through
Independent aluminium alloy connecting plate carries out increasing adjusting.
