According to the composite core used for the lead-out bushing for the high-voltage capacitor, the metal bar core and the bar core insulating bush constitute the body and the connecting way that the bar core insulating bush seamlessly covers the outer side of the metal bar core is adopted; therefore, the loss of state-owned rare soil can be reduced, the raw material are readily available, the composite core is light and convenient to install, the defect that capillary siphoning happens in a conductive copper wire inside an existing porcelain capacitor lead-out bushing during the temperature rising process of the capacitor can be solved, the problem of oil leak can be overcome, and the installation facture risk existing in a porcelain capacitor can be ameliorated.
Description
Technical field
The present invention relates to capacitor outlet casing tube field, particularly to the compound core body being applied to high-voltage capacitor outlet casing tube。
Background technology
At present, the capacitor that the whole world uses occurs that sleeve pipe core body is the porcelain condenser that pure porcelain casing tube, porcelain core and full skirt are formed in one。Its shortcoming is in that dust dirt is easily piled up on porcelain surface, reduces electrical property。For improving the hydrophobicity of porcelain full skirt, major part producer needs at porcelain full skirt surface spraying RTV glue-line, is greatly increased the cost of distribution system。Traditional porcelain condenser uses substantial amounts of rare soil, so territory soil protection is not had benefit yet。It addition, external a few large capacitor producer all purchases in China, it is simply that in order to avoid the loss of the rare soil of itself。Traditional porcelain condenser sleeve pipe RTV layer uses the time to dismantle from new spraying in 3～5 years, which increases the maintenance cost of power system。
Further, the conductive copper wire in existing market porcelain condenser outlet casing tube exists capillary tube siphonage in capacitor intensification work makes the oil in capacitive prolong on copper cash to sleeve upper end, permeability phenomenon occurs, there is the oil spill rate of about 15%；And there is the risk of fracture when mounted in porcelain condenser。
Summary of the invention
It is an object of the invention to overcome above-mentioned deficiency existing in prior art, it is provided that be applied to the compound core body of high-voltage capacitor outlet casing tube。
In order to realize foregoing invention purpose, the invention provides techniques below scheme:
Being applied to the compound core body of high-voltage capacitor outlet casing tube, by body be arranged on the metal connecting piece of body one end and form, described body is by metal bar core and is coated on the excellent core insulation set outside described metal bar core and forms。
As preferably, above-mentioned rod core insulation set is seamless to be coated on outside metal bar core。
As preferably, the preferred copper of material of above-mentioned metal bar core, ferrum, aluminum, nickel, zinc, chromium or lead。
Considering acquirement property and the cost of material, the material of above-mentioned metal bar core is it is preferred that copper or aluminum。
As preferably, the insulant preferred epoxy of above-mentioned rod core insulation set, epoxy resin are wound around glass fibre, phenolic moulding powder, polyurethane or plastics。
Consider acquirement property and the cost of material, above-mentioned insulant optimization polyurethane or epoxy resin。
Second purpose of the present invention is in that to provide what employ above-mentioned compound core body to be applied to high-voltage capacitor outlet casing tube。It is applied to high-voltage capacitor outlet casing tube, is made up of above-mentioned compound core body, the silicon rubber umbrella skirt sheath of the outside seamless cladding of described compound core body, the connector that is arranged on silicon rubber umbrella skirt sheath link cover plate place。
As preferably, adopting adhesive to carry out bonding connection between above-mentioned compound core body and described silicon rubber umbrella skirt sheath。
In order to improve the above-mentioned sealing being applied to high-voltage capacitor outlet casing tube further, as preferably, the above-mentioned connector being arranged on silicon rubber umbrella skirt sheath link cover plate place is electrically insulating silicone rubber nut。When high-voltage capacitor outlet casing tube is installed, described electrically insulating silicone rubber nut connects capacitor outlet casing tube and links cover plate。
Compared with prior art, beneficial effects of the present invention:
The present invention is applied to the compound core body of high-voltage capacitor outlet casing tube and is made up of body and the rod core insulation seamless connected mode being coated on outside metal bar core of set metal bar core and rod core insulation set, decrease state-owned rare soil losses, raw material easily takes, install light, overcome the conductive copper wire in existing porcelain condenser outlet casing tube in capacitor intensification work, there is the defect of capillary tube siphon, solve oil leakage problem, be also effectively improved the installation risk of breakage that porcelain condenser exists。
The present invention is applied to high-voltage capacitor outlet casing tube, reduces state-owned rare soil losses, reduces product weight, and raw material easily takes, it is light to install, and improves the installation risk of breakage that porcelain condenser exists, solves oil leakage problem；And there is good hydrophobicity, stain resistance, long service life can be improved, it is to avoid outdoor clean and maintenance；Without spraying RTV glue as tradition pure porcelain casing tube, reduce electric lines of force use cost and maintenance cost, exempt and safeguarding。
Accompanying drawing illustrates:
Fig. 1 is the structural representation that the present invention is applied to the compound core body of high-voltage capacitor outlet casing tube；
Fig. 2 is the structural representation that the present invention is applied to high-voltage capacitor outlet casing tube。
