Description
Technical field
A kind of composite bushing mounting structure that electric wire is drawn based on power capacitor is the utility model is related to, it is mainly applied
In field of electrical equipment.
Background technology
As China's power consumption constantly increases, the high voltage more and more higher of conveying, transmission power is also increasing, in electric power
During use, inductive load considerably beyond capacitive load, therefore, it is necessary to electricity container as compensation of power factor, electric capacity
Device is typically mounted in the chest of intermetallic composite coating and injects radiating insulating oil, and capacitor is drawn out to electricity by electric wire out of capacitor box
, it is necessary to be arranged sleeve pipe outside electric wire when on line of force road, prevent high pressure from leaking electricity, short circuit tripping operation, also to seal chest, prevent that radiating is exhausted
Edge oil flows out from electric wire connection point, in the prior art, the usual Ceramics material of the sleeve pipe, umbrella cover shape, but ceramic material is made
Big there is quality, transport, installation are inconvenient, and material hardness is high but frangible, fragile, and ceramics couple use with capacitor box sub-interface
When sealing ring seals, rolling technology is difficult control, oil leak hidden danger be present, in addition, ceramic material not resistant, can reduce insulating properties
Can, therefore, see that cost is very high, quality defect on the whole, in the prior art, Chinese patent CN201621390463.4 is disclosed
A kind of composite bushing, patent utilization plastics, the silicon rubber etc. for drawing electric wire based on power capacitor solves as composite bushing
Existing technical problem when ceramic material is as sleeve pipe, but there is also some new technical problems, such as plastics the patent
When rod couples with case lid 5, because the junction of the lower link post 41 in sticking plaster and threaded post 42 is in the cross-section with close to 90
The angle transition of degree, causes stress concentration, and intensity is bad, easily snaps off, in addition, when silicon rubber umbrella couples with lower link post 41,
Lower link post can not be reliably wrapped up, silicon rubber umbrella has the possibility for the lower link post 41 that comes off, so as to cause under electrical insulation capability
Drop, finally, when lower link post 41 is embedded in the indent of case lid 5, there is larger installation gap in both, and modeling is caused under certain pulling force
Position between charge bar and case lid can move.
Utility model content
The utility model is according to the above deficiency, provide a kind of composite bushing installation that electric wire is drawn based on power capacitor
Structure.
The technical solution of the utility model is：
A kind of composite bushing mounting structure that electric wire is drawn based on power capacitor, including：
Chest, power capacitor and radiating insulating oil are placed with chest, two delivery outlets, delivery outlet are offered on case lid
Couple with composite bushing structure；
Composite bushing, it is provided with bolt electrode, contact rod, sticking plaster, silicon rubber umbrella, nut and silicone rubber sleeve, bolt
Electrode couples with sticking plaster structure, and silicon rubber umbrella is enclosed on outside sticking plaster, and contact rod inserts the through hole of sticking plaster, contact rod

Sleeve pipe is fixed on case lid.
It should be noted that the utility model is directed in background technology, Chinese patent CN201621390463.4 knot
The improvement that structure is made, the utility model bolt electrode couple with sticking plaster structure, can be tightly placed in plastics by metal top cap
Outside the upper connecting column of rod, the sealing of bolt electrode and part silicon rubber umbrella.
The pyramidal structure of lower link post and case lid can substantially increase intensity, between the two can also reliable location, do not move
Position.
Bellmouth can be with indent relative to the cap surface of case lid, but this is not optimal scheme, preferably, the case lid
On bellmouth at least part relative to case lid cap surface evagination.
It should be noted that when cap surface evagination of the bellmouth relative to case lid, acute angle shape can be formed, is advantageous to increase
Add the intensity of case lid, when bellmouth indent, can be only formed obtuse angle, add the intensity of case lid can decline.
Preferably, the case lid is provided with prominent circle of the section for horn shape, described bellmouth is in prominent circle.
In order to further increase the intensity of case lid, the bellmouth inward flange extends to form inner ring.The formation of the inner ring is also
The openend that case lid inward flange can be reduced damages to sticking plaster.
Preferably, the horn shape bulge loop for going too far and being adapted to case lid angle-like protrusion is provided with the nut.
In order to improve insulating properties, the silicon rubber umbrella lower part can wrap up at least partially tapered body of lower link post.
For reliable isolation radiating insulating oil, the bottom of the threaded post offers conical cavity, in addition to cone seal
Circle, it is arranged in conical cavity, and conical seal ring is compressed by threaded post.
Similarly, the bottom of the threaded post offers cone cavity, in addition to taper sealing ring, and it is arranged on cone cavity
It is interior, compressed and sealed by threaded post.
Similarly, the upper extension of the silicone rubber sleeve can extremely be gone too far and threaded post horn shape bulge loop pressure by the case lid angle-like protrusion
Tightly.
The threaded post is made of plastics.
The utility model have rational in infrastructure, cost is low, it is in light weight, do not break up, antifouling property is good, insulating properties and machine
Tool strength character is more excellent, the reliable beneficial effect of positioning.
