Filled, existed inadequate by the risk of insulation breakdown, security after gas leakage using gas inside the insulator crossarm of heart tubing.It is limited to
This, composite insulation cross arm always can not in voltage levels large-scale promotion.
The content of the invention
The technical problems to be solved by the invention are to be directed to above-mentioned problem, there is provided a kind of extra-high voltage compound inslation
Cross-arm, construction is reasonable, electrical safety, and economy is more preferable.
Technical scheme is used by the present invention solves above-mentioned technical problem：A kind of extra-high voltage composite insulation cross arm, including
Insulate depression bar and insulated tension pole, and the both ends of the insulation depression bar and insulated tension pole are respectively equipped with flange gold utensil, insulation depression bar and absolutely
One end of edge pull bar is connected with tower body, and the other end is connected with conducting wire hanging point gold utensil, and grading ring is connected on conducting wire hanging point gold utensil,
Insulation depression bar is horizontally disposed with, and insulated tension pole is obliquely installed, it is characterised in that insulation depression bar is circumferentially uniform by several solid bars
Composition is arranged at intervals, uniform intervals are provided with several restraint joints to several solid bars vertically.
By such scheme, the restraint joint is made up of outer anchor ear and interior lining panel, and the outer anchor ear is regular polygon ring-type
Structure, the processing of interior angle arc transition, the interior lining panel is regular polygon platy structure, and angle is provided with circular groove, described
Circular groove formation circular hole corresponding with outer anchor ear interior angle, the circular hole and the solid bar phase configuration.
By such scheme, the solid bar is made by fiberglass, outer surface crimping silicon rubber umbrella skirt structure.
By such scheme, the insulated tension pole is solid hopkinson bar made of fiberglass, and outer surface crimps silicon rubber umbrella skirt knot
Structure.
By such scheme, the outer anchor ear and interior lining panel are made by fiberglass.
By such scheme, the insulation depression bar and insulated tension pole are two, and two thoroughly do away with one end of edge depression bars and tower body
It is connected, both ends of the other end respectively with the conducting wire hanging point gold utensil are connected, and two thoroughly do away with edge depression bar is set in angle, and two, which thoroughly do away with edge, draws
Bar is obliquely installed, and one end is connected with tower body, and both ends of the other end respectively with conducting wire hanging point gold utensil are connected.
The beneficial effects of the invention are as follows：A kind of extra-high voltage composite insulation cross arm is provided, insulation is formed by several solid bars
Depression bar, the insulation flashover problem in voltage levels composite insulation cross arm is effectively prevent, it is compound absolutely to solve voltage levels
Edge cross-arm caused floating potential problem due to sectionalized metallic connection, the solid bar not being segmented is compared to composite hollow tubing point
Section processing, can shorten, composite insulation cross arm cost is declined to a great extent, and stock utilization significantly carries in cross-arm insulated lengths
It is high.
