Abstract
The utility model discloses a tail sealing structure of an integral oiled paper capacitor bushing. The structure comprises threads which are arranged between a base and an epoxy glass steel cylinder and matched with one another, wherein an outer side sealing ring is arranged in a position where the base is connected with the epoxy glass steel cylinder; the base and the epoxy glass steel cylinder form a whole after being solidified; a conducting rod is tightly fixed with the base; a sealing ring is sleeved on the outer side of the conducting rod; an inner side sealing ring is arranged between the base and the conducting rod; the sealing ring and the inner side sealing ring are fastened on the base through a clamping ring and a clamping nut. The tail sealing structure ensures that lower porcelain bushing and the base are combined into a whole and then the conducting rod and the base are sealed, can guarantee the sealing of a sleeve even if insulation fault occurs, and can not cause ignition of a transformer.
Description
Technical field
it is fixing that the utility model relates to a kind of outlet insulation and machinery of power transformer, specifically a kind of tail sealing structure of integral type oiled paper capacity casing.
Background technology
current Oil-impregnated Paper Condenser Bushing in History afterbody is generally comprised of lower insulator 11, base 14, central guiding fulgurite 15 and seal, places after sealing ring 12 compresses and seal between each part, and Fig. 1 is traditional oils paper bushing tail sealing structure schematic diagram.Because each part of traditional structure sleeve pipe afterbody is disconnected from each other, once there be insulation fault, sealing is difficult to assurance, and oil leakage goes out, fire for transformer burning.
Summary of the invention
The problem existing in order to overcome prior art.The purpose of this utility model is to provide a kind of tail sealing structure of integral type oiled paper capacity casing, this structure becomes an integral body by lower insulator and base combination, then by conducting rod and base seal, even if there is insulation fault, also can guarantee bobbin seal, can not cause fire for transformer burning.
The purpose of this utility model is achieved through the following technical solutions:
A tail sealing structure for integral type oiled paper capacity casing, is characterized in that: this structure comprises and is arranged on the screw thread cooperatively interacting between base and epoxy glass fiber reinforced plastic cylinder; At base and epoxy glass fiber reinforced plastic cylinder junction, be provided with outside sealing ring, after base and epoxy glass fiber reinforced plastic cylinder solidify, form whole; Conducting rod tightens together with base; In conducting rod outside, be set with sealing ring, be provided with inner seal circle between base and conducting rod, sealing ring and inner seal circle are fastened on base by trim ring and spelling jack panel.
In the utility model, scribble epoxy resin on screw thread, epoxy glass fiber reinforced plastic cylinder, base and conducting rod form guarantees that transformer is the integral body of closed state to outside.Conducting rod bottom is provided with Ka Tai, and conducting rod tightens together with base by Ka Tai; Sleeve pipe current-carrying mode is to wear cable formula or the direct current-carrying pattern of conducting rod, while adopting the direct current-carrying of conducting rod, is placed with guide rod sealing ring in conducting rod and oil between terminal.
The utility model becomes an integral body by lower insulator and base combination, then by guide rod and base seal, even if there is insulation fault, also can guarantee bobbin seal, can not cause fire for transformer burning.

Embodiment
A tail sealing structure for integral type oiled paper capacity casing, is shown in Fig. 2 and Fig. 3, and this structure comprises base 4, and 7 of this base 4 and epoxy glass fiber reinforced plastic cylinders are provided with the screw thread 3 cooperatively interacting, and scribble epoxy resin 2 on screw thread 3; In base 4 and epoxy glass fiber reinforced plastic cylinder 7 junctions, be provided with outside sealing ring 61, after base and epoxy glass fiber reinforced plastic cylinder solidify, form an integral body; Conducting rod 5 bottoms are provided with Ka Tai, and conducting rod 5 tightens together with base 4 by Ka Tai; In conducting rod outside, be set with sealing ring 62, be provided with inner seal circle 63 between base and conducting rod, sealing ring 62 and inner seal circle 63 are fastened on base 4 by trim ring 8 and spelling jack panel 9.
In oil, between epoxy glass fiber reinforced plastic cylinder and base, adopt sealing ring to add the connected mode of screw thread, on screw thread, scribble epoxy resin, after solidifying, form an integral body.Ka Tai is arranged at the guide rod bottom of sleeve pipe, during sleeve pipe assembling, by means of this Ka Tai, first conducting rod is tightened together with base, epoxy glass fiber reinforced plastic cylinder, base, conducting rod form the integral body that can not destroy, guarantee that transformer is closed state to outside, flashover violent earthquake even in external flashover, fuse insulation breakdown, oil no matter, transformer completely cuts off all the time with extraneous, does not therefore also just have the risk of fire for transformer.
Fig. 4 is terminal and conduction electric pole axial seal schematic diagram in oil in the utility model.Sleeve pipe current-carrying mode can be to wear cable formula, also can adopt the direct current-carrying pattern of conducting rod, while adopting the direct current-carrying of conducting rod, in conducting rod and oil, 1 of terminal is placed with 10 sealings of guide rod sealing ring, guarantee that extraneous moisture cannot enter in transformer by guide rod inwall, cause Accident of Transformer.
