Abstract
The invention discloses a sealing pole which comprises an upper outgoing line terminal and an upper outgoing line rod connected to the upper outgoing line terminal, wherein a hood body is arranged outside a joint section of the upper outgoing line terminal and the upper outgoing line rod, and the hood body is conductively connected with the upper outgoing line terminal and the upper outgoing line rod. Compared with the prior art, the problem of non-uniform electric field distribution inside the sealing pole is solved, and the insulating ability of the sealing pole is improved.
Description
Technical field
The present invention relates to the design and fabrication technology field of high-voltage switch equipment, especially a kind of conductive element device that embeds in the solid insulating material.
Background technology
Existing pole, generally by insulated tension pole, flexible link, lower wire end, the arc control device assembly, epoxy package, upper outlet terminal consists of, on the pole on outlet terminal and the vacuum interrupter outlet rod be fixedly linked by screw, there is following point in this pole: owing to outlet rod on outlet terminal on the pole and the vacuum interrupter is fixedly linked by screw, between the two electric conductor coupling parts rough phenomenon is arranged, there is the part space, there is complicated electric field in the electric conductor coupling part during operation, skewness affects the insulating capacity of pole integral body.
Summary of the invention
The object of the present invention is to provide a kind of pole, this pole can solve in the prior art, and electric conductor internal electric field problem pockety has improved the insulating capacity of pole.
In order to address the above problem, the technical solution used in the present invention is: a kind of pole, the upper outlet rod that includes outlet terminal and be connected with described upper outlet terminal; The junction surface of described upper outlet terminal and described upper outlet rod is outside equipped with cover body, and described cover body is connected with described upper outlet terminal and described upper outlet rod conduction.
In the technique scheme, technical scheme can be more specifically: described cover body has a plurality of apertures, and the cover oral area of described cover body has to the crimping of cover inner bending.
Owing to adopted such scheme, the present invention compared with prior art has following beneficial effect:
The present invention on the outlet terminal on the pole be connected vacuum interrupter on the outlet rod junction surface cover body is set, the pole internal electric field is evenly distributed, guaranteeing does not have potential difference between each position in cover body; Simultaneously, described cover body surface has aperture, is convenient to bleed, is beneficial to exhaust; The cover body edge is smooth crimping, has avoided point discharge, and then reaches the effect of all pressing, and has improved the insulating capacity of pole.
Description of drawings
Fig. 1 is the sectional structure schematic diagram of pole;
Fig. 2 is the cover body structural representation.
Embodiment
Below in conjunction with accompanying drawing to more further detailed explanation of the present invention.
Pole shown in Figure 1 mainly comprises insulated tension pole 1, flexible link 2, lower wire end 3, arc control device assembly 4, epoxy package 5, upper outlet terminal 6, upper outlet rod 7, cover body 8; Upper outlet terminal 6 is installed in the upper end of epoxy package 5, epoxy package 5 inner chamber tops are arc control device, upper outlet rod 7 is located at the top of arc control device, upper outlet terminal 6 is fixedly linked by screw and upper outlet rod 7, outer ring at upper outlet terminal 6 and upper outlet rod 7 junction surfaces arranges cover body 8, and the cover oral area of cover body 8 has to the crimping of cover inner bending, has avoided point discharge, and then reach the effect of all pressing, improved the insulating capacity of pole.This pole adopts automatic pressure gelation process (APG), with arc control device assembly 4, use the poured with epoxy resin moulding with the upper outlet terminal 6 of cover body 8 and lower wire end 3, can prevent effectively that vacuum interrupter is impacted, the infringement of dirt and condensation, be not subjected to the impact of external environment, improved the insulating capacity of pole.Cover body 8 shown in Figure 2 is the hood-shaped structure of bowl, adopts the electric conducting material manufacturings such as copper or aluminium, can be directly welded on the described upper outlet terminal 6 or can be fixed in by other means outlet terminal 6; Cover body 8 has a plurality of densely covered apertures, is convenient to bleed, is beneficial to exhaust.The pole of assembling cover body 8 can make the pole internal electric field be evenly distributed, and guaranteeing does not have potential difference between each position in cover.
Claims (2)
