Description
[technical field]
The utility model relates to the T ﹠ D Technology field, particularly a kind of capacitor unit outlet casing tube binding post and wiring construction thereof.
[background technology]
See also shown in Figure 1, the structure of present high-voltage power capacitor unit outlet casing tube binding post commonly used is: in order to solve the tight connectivity problem of loose copper stranded conductor 1 and binding post 2, between them, increased a kind of transition connecting structure, namely increased the flexible copper sheet of inter-embedding type band about two 10mm at the screw rod 21 of binding post 2, industry is commonly called as breathes out not frame 3.Breathing out frame 3 not for two will need the copper stranded conductor 1 of the type of weave that connects to clamp, breathing out not by the nut 22 on the binding post screw rod 21 with two, thereby frame 3 clamps 1 clamping of this copper stranded conductor, to breathe out simultaneously frame 3 not and push down fully with six sides on binding post 2 main bodys and contact, conduct electricity with fully being connected of binding post 2 thereby reach copper stranded conductor 1.There are a lot of shortcomings this Kazakhstan not frame 3 structures, now the high-voltage capacitor of electrical network often because thereby this binding post 2 and twisted wire connect 1 to be touched insufficient both contact points electricity sparkings and cause binding post 2 heatings that the gasket seal of outlet casing tube is burnt, finally causes this capacitor unit leakage of oil.This hidden danger has become to cause the very large factor of of high-voltage capacitor unit operation troubles now.Integrate the not main following points of shortcoming of the binding post of shelf structure of this Kazakhstan:
(1) it is more that twisted wire arrives between the binding post of outlet casing tube process contact point from the outside, and twisted wire is not directly to be connected with copper tip, and the connection between them is to breathe out not by one that the transition of frame connects.Being connected between twisted wire and the copper tip comprises copper stranded conductor 1 and breathes out not frame 3 contact points, breathes out not frame 3 and copper tip 2 contact points.Contact point is more, and probability is larger because loose contact causes electricity sparking heating between the contact point.
(2) to breathe out shelf structure twisted wire not be loose type of weave thus with breathe out that not the frame contact-making surface is less, contact resistance is larger.
(3) thus whether breathe out not shelf structure reliably has been connected can not macroscopic examination uncontrollable to electric power construction field twisted wire and copper tip.
(4) original structure to increase by one the cover copper breathe out not frame, cost is higher.
[utility model content]

Preferably, offer four adjacent sides that are into 90 ° on the main body and opened endoporus; Threaded post is perpendicular to these four endoporus, and is positioned on the center line of main body.
Preferably, do not diminish when making up than the perforate seam when the aperture that under external force perforate of endoporus upper surface seam makes rear endoporus up.
The aperture of endoporus was not 8mm when preferably, the perforate seam made up; The aperture that the perforate seam makes rear endoporus up is 7.5mm.
Preferably, the upper surface of main body is provided with the section of caving in of annular.
The capacitor unit outlet casing tube comprises binding post, twisted wire and nut with the wiring construction of binding post; The link of twisted wire is the columnar metal that twisted wire is melt into, and this link inserts in the endoporus of binding post, and nut is tightened against on the threaded post, and the link that the perforate seam makes up twisted wire is anchored in the endoporus of binding post.
Preferably, described nut is locking anti-loose structure nut.
Preferably, described wiring construction also comprises pad, and this pad is sheathed on the threaded post, is locked between the main body of nut and binding post.
Preferably, described twisted wire is copper stranded conductor.
The aperture of endoporus was not greater than the external diameter of link when preferably, the perforate seam made up; The perforate seam makes the aperture of rear endoporus up less than the external diameter of link.
Compared with prior art, the utlity model has following advantage:
(1) the utility model structure will be breathed out not the transition linkage function of frame and be removed, and twisted wire directly is connected with binding post.Only has a process contact point between twisted wire and the binding post, between the two because the hidden danger of loose contact reduces greatly.
(2) the utility model structure twisted wire and binding post link have passed through special processing, and thin strand of loose braiding structure has been melt into a standard copper rod solid construction.Therefore be connected to solid the contact between twisted wire and the binding post, contact-making surface is larger, and contact resistance is little.
Whether (3) being attached thereto the solid copper bar external diameter that end is melt into the aperture of twisted wire connecting hole and twisted wire on the binding post that relates to of the utility model structure can strictly control, as long as whether connected the hole seam of reliably seeing copper tip between them make up.Like this can macroscopic examination.
(4) the nut band automatic fastening function of the utility model structure, the fine assurance twisted wire of energy and binding post close contact are reliably and with long-term.
(5) the utility model structure is saved a cover copper and is breathed out not frame, saves Financial cost.
