Description
Technical field
The utility model relates to a kind of 220kV combined electrical apparatus technical field, specifically in a kind of 220kV combined electrical apparatus for the structure of fixing branch bar inner wire.
Background technology
In 220kV combined electrical apparatus, the conventional fixed form of branch bar inner wire is that two ends benzvalene form adopts insulator to connect, the one end that is conductor is fixed on disc insulator, the other end is fixed on another disc insulator by Mume flower contact, in order to prevent end of bus bars electric discharge, that disc insulator outside at the end place that is positioned at branch bar must add radome, see label 9 in Fig. 1, just outside in housing of this radome, in order to protect insulator not impaired, and protection air chamber is set, just need to be in the end of housing, the outside of radome increases a protective casing and covers in radome outside, see label 10 in Fig. 1, this structure has caused the complex structure of branch bar, parts are more, cost is high.
Summary of the invention
The utility model provides a kind of simple and reasonable for structure in order to overcome above-mentioned defect, the fixing structure of branch bar inner wire that cost is low.
The technical solution adopted in the utility model is: a kind of structure for fixing branch bar inner wire, comprise branch conductors, branch's housing, Mume flower contact and disc insulator, disc insulator is arranged on the link of branch's housing, branch conductors is positioned at branch's enclosure interior, its one end is connected with disc insulator, the other end arranges Mume flower contact, it is characterized in that: also comprise insulation column, holder and cover plate, described insulation column is the little taper shape of the large one end of one end diameter diameter, that end that diameter is little is connected with Mume flower contact by bolt, that end that diameter is large is connected with holder by bolt, holder is disc, the diameter of holder is greater than the diameter of insulation column, the junction of the joint face of holder and insulation column and the periphery of holder is arc transition, the outside of holder is connected with cover plate, cover plate is arranged on housing, that end relative with that side of disc insulator, between cover plate and housing, be provided with sealing device.
The disc insulator that tradition is connected Mume flower contact by the utility model has been modified into insulation column, insulation column is fixed in branch's housing by holder and cover plate, utilizing insulation column to connect Mume flower contact is fixed branch conductors, insulation property and the fastness of branch conductors are not only guaranteed, and this structure has been removed in traditional structure after the disc insulator of that end of the branch bar end, also save the protective casing of radome and radome outside, simplify the structure of branch bar, reduce parts, reduced cost.
Brief description of the drawings
Fig. 1 is the fixed structure of the branch bar inner wire before improving.
Fig. 2 is schematic diagram of the present utility model.
Fig. 3 is the A portion enlarged drawing in Fig. 2.
Embodiment
Now by reference to the accompanying drawings the utility model is further described, Fig. 2 is a kind of embodiment of the present utility model, comprise branch conductors 1, branch's housing 2, Mume flower contact 3 and disc insulator 4, disc insulator 4 is arranged on the link of branch's housing 2, branch conductors 1 is positioned at branch's housing 2 inside, its one end is connected with disc insulator 4, the other end arranges Mume flower contact 3, in the utility model, also comprise insulation column 5, holder 6 and cover plate 7, described insulation column 5 is the little taper shape of the large one end of one end diameter diameter, that end that diameter is little is connected with Mume flower contact 3 by bolt, that end that diameter is large is connected with holder 6 by bolt, insulation column 5 is normally made up of epoxide resin material, there are good insulation property, pyramidal structure can be guaranteed good intensity.Holder 6 is disc, normally made by aluminium sheet, also can make of steel plate, the diameter of holder 6 is greater than the diameter of insulation column 5, holder 6 is arc transition with the junction of the joint face of insulation column 5 and the periphery of holder 6, arc transition can be avoided wedge angle Discharge Phenomena, the outside of holder 6 i.e. that side opposing with insulation column 5 is connected with cover plate 7, cover plate 7 is arranged on housing, that end relative with disc insulator 4 those sides, between cover plate 7 and housing, be provided with sealing device, sealing device adopts sealing ring conventionally, cover plate 7 is normally made up of aluminium sheet, also can manufacture with steel plate.Branch conductors 1 one end is connected with disc insulator 4, and the other end is connected with insulation column 5 and cover plate 7 after inserting Mume flower contact 3, and branch conductors 1 has just been fixed on branch's housing 2 inside like this.Holder 6 in the utility model all connects by bolt while connection with insulation column 5 and cover plate 7, and the bolt hole arranging for fear of wedge angle electric discharge is by adopting counter bore structure, and bolt head is positioned at inside, hole.
The disc insulator 4 that conventional mounting is connected Mume flower contact 3 by the utility model has been modified into the structure by insulation column 5 fixing Mume flower contacts 3, insulation column 5 is fixed in branch's housing 2 by holder 6 and cover plate 7 again, with the common branch conductors 1 that supports of disc insulator 4 on opposite.Utilizing insulation column 5 to connect Mume flower contact 3 is fixed branch conductors 1, insulation property and the fastness of branch conductors 1 are not only guaranteed, and this structure has been removed in traditional structure after the disc insulator 4 of that end of the branch bar end, also save the protective casing of radome and radome outside, simplify the structure of branch bar, reduce parts, thereby reduced cost.
The utlity model has simple and reasonable for structure, the feature that cost is low.
