Abstract
A portable ground wire power used in a transmission line is composed of a wire clamp and an insulator spindle being connected together. The insulator spindle is divided into an insulator spindle upper segment and an insulator spindle lower segment; and the insulator spindle upper segment and the insulator spindle lower segment is connected through a universal joint. The novel wire clamp can rotate around the universal joint with the insulator spindle upper segment, so that the wire clamp can be used on an upper segment of a transmission line and a tension bearing rod according to grades. The portable ground wire power used in a transmission line has the characteristics of reasonable structure design, and safe and reliable ground connection.
Description
Technical field
The utility model relates to the used for transmission line portable power transmission line of used for transmission line earth connection in the electric power system, particularly wire clamp adjustable angle.
Background technology
The installing earth connection is to prevent in the work that repair apparatus is charged suddenly, prevent that repair apparatus from closing on the important safety measure that charging equipment produces induced electricity, prevents electrostatic hazard, and it is the important means that guarantees that the anti-person of operating personnel gets an electric shock.Yet in real work, use portable grounding wires on dead line " hanging earthing conductor " this seem shirtsleeve operation, but because of the portable grounding wires unreasonable structure of use and the influence of operating environment, there is very big problem in the staff in earth connection work is installed, for work brings potential safety hazard.
The existing wrong operating position of portable grounding wires in power transmission lines overhauling: it has two kinds of split-phase type and composite types portable grounding wires, the circuit of 110kV and above electric pressure generally adopts the split-phase type earth connection, utilizes the every indivedual mutually ground connection of iron tower or cement pole ground lead.
The earth connection that uses in our work mostly is the portable grounding wires of band straight rod type insulating bar, this portable earth connection be applicable to the direction vertical with lead hang (as in the transformer station by ground hold insulating bar upwards hang, 10kV circuit and lead operation apart from the equipment of lacking on the staff can be in the direction vertical with lead hang into).
The installation method of this earth connection can be used on distribution line well, but it is far away to reach shaft because conductor spacing is horizontal on 110kV and above circuit, the operating personnel horizontal but or can not reach the insulating bar of earth connection on the shaft, and earth connection conductor wire end wire clamp and insulating bar are that reason such as straight line causes to install earth connection on 110kV and above circuit and many nonstandard behaviors occur;
1, on 110kV and above circuit straight line pole, work, since lead at horizontal stroke that the operating personnel stands but below, and the equipment electrical distance is big, the operating personnel can only be with the earth connection reversal of the natural order of things on lead, and be wrapped in the ground connection copper cash and be fixed in horizontal stroke on the insulating bar but on the limit, this behavior is easy to touch at work the danger that ground connection copper cash and earthing clamp get loose, line scan pickup coil side wire clamp opening is up the time, nature whereabouts and upset can appear in earth connection easily, the operating personnel can only habitually catch the ground connection copper cash that it is retracted, and This move has the danger that human body is sealed in grounded circuit.
This with earth connection reversal of the natural order of things on lead, insulating bar is fixed on horizontal stroke but on method, the most common in line maintenance, the mode of reversal of the natural order of things but is the main cause that earth connection gets loose.
2, seem more inconvenient at strain insulator bar installing earth connection, in the position that the work of strain insulator bar is stood because of the staff, when using insulating bar installing earth connection, because of line scan pickup coil side wire clamp opening parallel with lead, can't directly install, the operating personnel tends to utilize earlier other instruments in the operation, and arrival lead place refills and establishes earth connection earlier, causes the operation against rules of no earth connection contact wire.
Before the work, it is the generation of avoiding these phenomenons that the people is responsible in work, can only send the work group of special installing earth connection more, at adjacent another basic shaft tower installing earth connection, must divide extension one winding ground wire in the both sides, working point by safety requirement work teams and groups, make and minimum in the work will arrange 4 operation personnel to install earth connection specially more, and transmission line environment of living in is many in outlying mountain area, sometimes arrive a basic shaft tower and will spend 1 hour time, after the operating personnel of special installing earth connection finishes the work, licensed the going into operation of construction teams and groups ability, this makes the operating time prolong the time lengthening of line outage.
The utility model content
The purpose of this utility model provides a kind of wire clamp adjustable angle, the reliable used for transmission line portable of attachment security power transmission line.
This novel purpose is achieved in that a kind of used for transmission line portable grounding wires, is connected to form by wire clamp and insulating bar, and insulating bar is divided into insulating bar epimere and insulating bar hypomere, and connects through the direction joint between insulating bar epimere and the insulating bar hypomere.
Compared with prior art, the utlity model has following characteristics:
1, structural design more reasonable, be suitable for using in various restricted occasions.
2, the rotational angle as requested of the wire clamp on the insulating bar epimere, the articulating of convenient on-the-spot and lead.
3, the ground connection connection is more reliable, has improved the fail safe of ground connection.
Description of drawings
Fig. 1 is this novel front view.
Fig. 2 is the front view after wire clamp shown in Figure 1 turns an angle with the insulating bar epimere.
Embodiment
Fig. 1, Fig. 2 illustrate, and this used for transmission line portable grounding wires is connected to form by wire clamp 3 and insulating bar, and insulating bar is divided into insulating bar epimere 1 and insulating bar hypomere 2, and connect through direction joint 4 between insulating bar epimere and the insulating bar hypomere.
Flexibility at live line working tool using insulation club head fastening means, the inventor is divided into two sections with insulating bar, a universal joint is installed between two sections insulating bars, is made it to form the earth connection wire clamp that can rotate, so just can easily on transmission line straight line and strain insulator bar, use.
Claims (1)
1. used for transmission line portable grounding wires, connect to form by wire clamp (3) and insulating bar, it is characterized in that: described insulating bar is divided into insulating bar epimere (1) and insulating bar hypomere (2), and connects through direction joint (4) between insulating bar epimere and the insulating bar hypomere.
