Description
Technical field
Porcelain insulation equipment technical field is the utility model is related to, specially a kind of high-voltage insulation porcelain bushing fixed structure.
Background technology
As the operation element commonly used in insulation applications, insulated porcelain sleeve is primarily used to the container of electric interior insulation.Assembling
When, in conventional assembling fixed structure, typically high-voltage insulation porcelain bushing is bolted to connection and is fastened on its case lid
On case lid, because bolt is usually conductor structure made of metal material, this conductor structure can reduce high-voltage insulation porcelain bushing top
The creep age distance of conductor so that the big heavy discount of insulating properties of high-voltage insulation porcelain bushing, meanwhile, when being fastened using bolt, hold
Quick detachable, theftproof performance is also poor.
For these reasons, the production of many insulated porcelain sleeves and assembling producer can all carry out specific structure improvement to it,
Such as in the U of Chinese utility model patent CN 201859716, just by stirrup and epoxy resin encapsulated layer to high-voltage insulation porcelain bushing
It is relatively fixed with case lid, although this structure can guarantee that being relatively fixed between high-voltage insulation porcelain bushing and case lid, but stirrup
Higher is required to the prestressing of stirrup with the coupling part of epoxy resin encapsulated layer, if pretightning force not enough easily causes stirrup, epoxy
Axial motion or rotation displacement occur between resin embedding layer and insulated porcelain sleeve, and then causes connective stability to decline, and
Epoxy resin encapsulated layer or even insulated porcelain sleeve is easily caused to be destroyed if pretightning force is excessive, thus the operation warp to operator
It is high to test requirement.
Utility model content
The technical problem that the utility model solves is to provide a kind of high-voltage insulation porcelain bushing fixed structure, above-mentioned to solve
The shortcomings that in background technology.
The technical problem that the utility model solves is realized using following technical scheme：
High-voltage insulation porcelain bushing fixed structure, including insulated porcelain sleeve, case lid and epoxy resin encapsulated layer, set on the case lid
The mounting hole passed through for insulated porcelain sleeve is equipped with, two pieces of spacing otic placodes, the spacing otic placode are then provided with mounting hole lower surface
It is oppositely arranged, and is 1/6 ~ 1/5 annuli arrangement；Then set on the insulated porcelain sleeve in the corresponding position bottom through mounting hole
There are two convex ranks to match with spacing otic placode, the convex rank is oppositely arranged, and is 1/6 ~ 1/5 annuli arrangement；And the ring
Epoxy resin embedding layer is carried out pouring encapsulation in case lid lower surface to insulated porcelain sleeve, and spacing otic placode and convex rank are encapsulated in into epoxy
In resin embedding layer.
As further improvement of the utility model,
The internal diameter of the spacing otic placode is less than the external diameter of the convex rank, and during encapsulated moulding, spacing otic placode and convex rank are same
Heart septum assembles, and the epoxy resin encapsulated layer be column encapsulating structure, and its external diameter than spacing otic placode and convex rank outside
Big 30 ~ the 50mm in footpath.
The convex rank is formed in one with insulated porcelain sleeve.
The spacing otic placode is formed in one with case lid.
One layer of thermostable fluorine rubber layer is formed on the lateral surface of the convex rank and the spacing otic placode to improve into
Structural stability after type.
Beneficial effect：The utility model need not be by the use of stirrup as fixation, thus moulding process is simpler, uses simultaneously
The spacing otic placode taken shape on case lid and the convex rank taken shape on insulated porcelain sleeve carry out fiber, coordinate epoxy resin encapsulated layer
Maintenance is carried out, can effectively prevent that axial motion or rotation displacement occur between epoxy resin encapsulated layer and insulated porcelain sleeve, because
And it can ensure that its stability is more preferable on the basis of insulating properties are ensured.
Brief description of the drawings
Fig. 1 is the schematic diagram of the utility model preferred embodiment.
Fig. 2 is the Section A-A schematic diagram in Fig. 1.
Wherein：1st, case lid；2nd, epoxy resin encapsulated layer；3rd, insulated porcelain sleeve；4th, convex rank；5th, the first thermostable fluorine rubber layer；
6th, spacing otic placode；7th, the second thermostable fluorine rubber layer.
Embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines and is specifically illustrating, and the utility model is expanded on further.
Referring to the preferred embodiment of Fig. 1, Fig. 2 high-voltage insulation porcelain bushing fixed structure, in the present embodiment, insulated porcelain sleeve 3
Umbrella section top be provided with two convex ranks 4 being oppositely arranged, and mounting hole is provided among case lid 1, and mounting hole bottom with
Mounting hole has been arranged concentrically two pieces of spacing otic placodes 6.Wherein, 1/5 annuli arrangement that convex rank 4 is formed in one with insulated porcelain sleeve 3, and
The first thermostable fluorine rubber layer 5 is formed in its cylinder partial；And the 1/5 anchor ring knot that spacing otic placode 6 is formed in one with case lid 1
Structure, and the second thermostable fluorine rubber layer 7 is formed on its outer surface.
During assembling, insulated porcelain sleeve 3 is passed through into case lid 1 from top, and it is solid being spaced convex rank 4 and spacing otic placode 6 after
Positioned after fixed using mould, then carry out epoxy resin encapsulated, and ensure the external diameter ratio of the epoxy resin encapsulated layer after embedding shaping
The big 50mm of external diameter of spacing otic placode 6.
The present embodiment closes insulated porcelain sleeve 3 and case lid 1 by using poured with epoxy resin, meanwhile, utilize convex rank 4 and limit
Position otic placode 6 carries out fiber and fixation, insulated porcelain sleeve 3 can tighten together with case lid 1, because fastening part is arranged in casing
Portion, and be the cast fastening of large area, theftproof performance greatly improves, and better tightness, will not also reduce high-voltage insulation porcelain bushing
Upper conductor and the creep age distance of lower end conductor.And the utilization of convex rank 4 and spacing otic placode 6 can also effectively improve the steady of connecting portion
Qualitative and connection tight type, prevents it from axial motion or rotation displacement occurring when by external impact, meanwhile, shaping
It is simpler, quick, reduce the use of other external fastenings, technological requirement is also lower.
