Description
Technical field
The utility model relates to the novel 35kV earth brace of a kind of Substation Switch Changing Operation.
Background technology
In the grid switching operation of current electric power system power transformation operation specialty, when turning maintenance for the power failure of 35kV equipment, traditional 35kV grounding wire pole due to structure single, the aluminium row various for scene and wire mounting means, execute-in-place difficulty is not only increased when mounting earth connection, in such cases because mounting earth connection time delay thus causing operation overtime, also shorten the repair time of equipment simultaneously.
Utility model content
The purpose of this utility model is to provide the novel 35kV earth brace of a kind of Substation Switch Changing Operation, can mount flexibly the aluminium row of on-the-spot different installation and reach reliable ground, speed and the efficiency of grid switching operation can also be improved, improve Earthing Reliability, improve the safety index of operation field.
The novel 35kV earth brace of a kind of Substation Switch Changing Operation, comprise insulating bar, at the head of this insulating bar, earth clip is installed, its special feature is: described insulating bar is made up of long insulating bar and short insulating bar, junction between this long insulating bar and short insulating bar is the step surface of Z-type, and in this junction, connector is installed, thus by long insulating bar and short insulating bar hinged.
One end of its short-and-medium insulating bar is fixedly connected with earth clip, bottom long insulating bar, be provided with draw ring.
Novel 35kV earth brace of the present utility model is through on-the-spot actual investigation and architecture advances, grounding wire pole is transformed into multi-angle rotation structure, and do not affect the security feature of earth brace, adapt to the condition of the hanging earthing conductor of different occasion, shorten the operating time, improve the reliability of earth connection simultaneously, ensure the safety that maintainer works.This improvement solves in grid switching operation, and during mounting earth connection, conventional ground rod structure is single, cannot the present situation of reliable ground, also extends the operating time of maintainer simultaneously, improves equipment reliability of operation.Have flexibly, the reliable characteristic such as adjustable.When mounting 35kV ground wire in operation, the aluminium row of on-the-spot different installation is mounted flexibly and can reach reliable ground, speed and the efficiency of grid switching operation can be improved, improve Earthing Reliability, improve the safety index of operation field.During hanging earthing conductor, first according to aluminium row's mounting means and position, on-the-spot relative angle of reconciling jaw and insulating bar, can finish the work smoothly.Improve and see operating efficiency and reliability.Novel connecting the thin end of the scroll of the present utility model is adopted to operate, the earth connection installation task of various different angles, height can be realized, and installing after ground connection completes and can form good fixing by the fixed pull ring of earth brace afterbody, effectively can preventing from loosening because touching the contact portion caused, also not affecting the safe distance of surrounding devices.When hang space be less than conventional ground rod long time, Novel connecting the thin end of the scroll is also by suitably adjusting adaptation site environment.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model provides the novel 35kV earth brace of a kind of Substation Switch Changing Operation, comprise insulating bar, at the head of this insulating bar, earth clip 4 is installed, described insulating bar is made up of a long insulating bar 2 and a short insulating bar 3, junction between this long insulating bar 2 and short insulating bar 3 is the step surface (namely the cross section of junction is right angle cascaded surface) of Z-type, and is provided with connector in this junction, thus by long insulating bar 2 and short insulating bar 3 hinged.One end of its short-and-medium insulating bar 3 is fixedly connected with earth clip 4, is provided with the draw ring 1 of metal material bottom long insulating bar 2.
Using method of the present utility model is:
Long insulating bar 2 and short insulating bar 3 designing two portions are survived buckle-shaped formula by earth brace of the present utility model, the rotation at the 180 degree of angles, face that are up to the standard, the rotation of vertical an angle of 90 degrees, are difficult to the problem of reliable mounting during to solve operation.This transformation does not destroy the dielectric strength of insulating bar, do not affect earth clip 4 and conduct electricity jaw place conductive capability yet, it horizontally rotates partial design, and to be that bolt is fixed adjustable rotary, rotational angle reaches 180 degree, it is the two bolt fixing rotary of thimble tube near jaw 2cm place, its width of rebate is 1cm, notch arc angle is, can vertical 90-degree rotation angle, earth brace can be made to realize multi-faceted rotation, installing fixed diameter at insulating bar afterbody is the draw ring 1 of the metal material of 2.5cm, can reinforce when ground connection with insulating bar, avoids earth connection loose and swing.
Claims (2)
