Abstract
The invention relates to a split three-phase solid-sealed insulated upper outlet seat component used for an outdoor ring main unit of a power system. The component is provided three rectangular seat bodies which are arranged abreast. Each seat body is provided with a bus jack is reserved along a length direction. The bottom of the jack is provided with a quincuncial contact finger. The top of each seat body is provided with a raised connecting seat. The three connecting seats are arranged in a staggering way. The center of each connecting seat is provided with a conductive pole. The middle part of the conductive pole is provided with a jack in which a watchband contact finger is arranged. A frame-shaped groove is reserved around the conductive pole on the connecting seat. The two sidewalls of the groove are inclined surfaces. A copper insert is wrapped in the seat body. One end of the copper insert is connected with a corresponding quincuncial contact finger, and the other end of the copper insert is connected with a corresponding conductive pole. The component solves the problems of low insulativity, high manufacture cost, inconvenience of maintenance and inadaptability to severe environments caused by the adoption of an exposed copper bar in outlet connection in the conventional ring main unit, and is particularly applied to the lower outlet of a main loop of the outdoor ring main unit with the three-phase AC of 50Hz and the rated voltage 12kV.
Description
(1) technical field: the present invention relates to the important spare part that uses in the outdoor ring main unit of power transmission system, especially a kind of split type three-phase seals insulation admittedly and goes up the outlet holder assembly.
(2) background technology: in the outdoor ring main unit that electric power system is both at home and abroad used at present, all adopt exposed copper bar to connect layout between each parts of last outgoing line device, only utilize air insulation or compound inslation each other; The requirement of space length between each parts is bigger like this, and insulation property are poor, thereby cause whole ring main unit volume big; Manufacturing cost is high; Assemble complicacy, safeguard inconvenience, maintenance period is long and can not adapt to the rugged environment use.
(3) summary of the invention: the object of the invention will solve in the existing outdoor ring main unit exactly; The above-mentioned a series of problems that adopt exposed copper bar connected mode to be brought between each parts of last outgoing line device provide a kind of split type three-phase to seal insulation admittedly and go up the outlet holder assembly.
Concrete scheme of the present invention is: a kind of split type three-phase seals insulation admittedly and goes up the outlet holder assembly, and it is characterized in that: have three rectangular pedestals that are arranged side by side, each pedestal upper edge length is to having the bus jack; The opening of three bus jacks is towards unanimity, and the bottom of jack is equipped with the plum blossom fingertip, and is provided with protruding Connection Block at the top of each pedestal; Wherein the Connection Block on first pedestal is positioned at the front end of pedestal, and the Connection Block on second pedestal is positioned at the middle part of pedestal, and the Connection Block on the 3rd pedestal is positioned at the tail end of pedestal; At the middle part of each Connection Block one conductive pole is installed; The conductive pole middle part has jack, and the watchband fingertip is housed in the jack, on each Connection Block, has a shaped as frame groove around conductive pole; The two side of groove is the inclined plane, forms trapezoidal cross-section groove wide at the top and narrow at the bottom; In each pedestal, also be enclosed with copper insert, an end of copper insert is connected with the plum blossom fingertip, and the other end is connected with conductive pole.
Three rectangular pedestals are to adopt the bisphenol A type epoxy resin moulding by casting described in the present invention.
Reliable for guaranteeing to use insulation, the bus jack degree of depth described in the present invention on the pedestal is not less than 200mm.
The shaped as frame groove of opening on the Connection Block described in the present invention is square-shaped frame or circular frame.
The present invention has the following advantages:
1, the present invention adopts high performance bisphenol A type epoxy resin moulding by casting, and through the manufacturing of APG (automatic pressure gel) art designs, it is strong to have insulating properties, good heat dissipation, and advantages of high strength, and install and also practiced thrift the cabinet space greatly.Used bisphenol A type epoxy resin solidifies convenient, and the crystallization tendency is little, and sticking contracting property is strong, and shrinkage is low, high Jie's performance, and anti-surface leakage, anti-electric arc is good, dimensionally stable, anti-mould, ultraviolet aging resistance, weather, characteristics such as antistatic.
2, the present invention is used for ring main unit, and insulation is reliable, need not to pour in the cabinet insulating gas, can prevent pernicious gas contaminated environment such as sulphur hexafluoride and the harm that human body is caused, and saves the human living space.
3, the shaped as frame groove among the present invention is the design of trapezoidal seal groove, has realized all insulation, and is hermetically sealed, the few maintenance, and the anti-advantage of leaking of coagulating has improved equipment dependability and safety in operation greatly.
4, three-phase carries out moulding by casting respectively, and install adjustment is convenient in the use that is arranged side by side again; And this bus connects the connection that is superior to the exposed copper part, is applicable to outdoor ring main unit, simultaneously because volume is little; Can make the small designization of ring main unit, meet the trend of switch cubicle miniaturization Design.
5, three-phase connects with bus and has adopted not conllinear, and solid insulation has been realized miniaturization when reaching safe spaced apart, abundant reasonable use has been realized in the cabinet space.
6, be connected with the isolated bus flange assembly through setting-in watchband fingertip in the conductive pole jack in the present invention, the render electrical field distribution is even, no partial discharge and ageing of insulation phenomenon.
