Description

The changeable wire clamp of extra-high voltage direct-current pipe bus
Technical field
The utility model relates to the female class gold utensil of power transmission and transformation line equipment pipe field, especially relates to the changeable wire clamp of a kind of extra-high voltage direct-current pipe bus.
Background technology
For the big a lot of pipe bus of pipe bus external diameter conventional pipe bus external diameter, its supporting gold utensil will cause a large amount of wastes of material as pipe bus gold utensil design routinely, simultaneously also can cause very big difficulty, therefore will consider new the supporting gold utensil of big caliber pipe bus to gold utensil production.The big changeable wire clamp of caliber pipe bus is a kind of supporting gold utensil of big caliber pipe bus, it is the transition gold utensil that connects a multiple conducting wires and a pipe bus, it not only bearing electric current from lead to pipe bus smooth and easy transition, and to lead to attractive in appearance the playing an important role that seamlessly transit of pipe bus, a changeable in addition wire clamp is that corona easily produces the position, even produce fireball, send noise, influence near the resident's of circuit normal life, even the safe operation that jeopardizes circuit, to carry out the mature consideration design based on this to a changeable wire clamp.
Summary of the invention
The purpose of this utility model is to solve direct current ultra high voltage current conversion station bassoon bus is connected, installs inconvenience and easy corona with lead problem.
To achieve these goals, the utility model provides a kind of extra-high voltage direct-current pipe bus a changeable wire clamp,
Comprise left wire clip body, right wire clip body, wire clamp cover plate and securing member, one end of two wire clip bodies is respectively arranged with the pipe bus duct, the pipe bus duct position of two wire clip bodies is fixed on the pipe bus by securing member, the other end of two wire clip bodies is provided with a wire clamp groove respectively at least, at least be provided with a wire clamp cover plate on each wire clamp groove respectively, the wire clamp cover plate is fixed on the wire clamp groove by securing member, and the outer surface of two wire clip bodies and wire clamp cover plate is arranged to arc surface.
Retainer shaft is to be arrangeding in parallel between pipe bus duct and the wire clamp groove.
Retainer shaft is to vertical setting between pipe bus duct and the wire clamp groove.
Described securing member is nut bolt and/or screw.
Be with sealing ring on bolt between fastening of two wire clip bodies and wire clamp cover plate and two wire clip bodies and/or the screw.
The utlity model has following advantage:
1, the utility model compact conformation, simple, attractive in appearance, six changes, one wire clamp mainly contains wire clip body and the wire clamp cover plate forms by Bolt Connection, and wire clamp steps up to manage bus and lead by tightening of bolt.
2. the utility model uses simple installation.Reduce construction volume, saved cost.Can satisfy the long-term instructions for use of power transmission and transformation line.
3. the utlity model has the anti-corona effect of considerable energy saving.Wire clip body and wire clamp cover plate adopt non magnetic high-strength aluminum alloy material, and the design of the slyness of wire clip body and wire clamp cover plate, and securing member is hidden in wire clip body fully, and corona is no longer produced, and comparing wire clamp more has energy-saving effect.
4. the utlity model has superior decay resistance.Because wire clip body and wire clamp cover plate adopt aluminum alloy materials, securing member adopts stainless steel material, makes product more corrosion-resistant.
