Abstract
The utility model discloses a composite insulating material bushing type capacitor comprising a capacitor body. The capacitor is characterized in that the outer surface of the capacitor body is provided with a composite bushing, and the capacitor is internally provided with a capacitor core and an insulating material. The composite insulating material bushing type capacitor has the advantages of light weight, good climate resistance performance of flange binding, strong insulating performance of the outer surface, good explosion proof, shockproof, anti-shock capability and convenient installation and transportation.
Description
Technical field
The utility model relates to capacitor, specifically is a kind of composite insulating material bushing type condenser.
Background technology
In 35kV～1000kV electric power system, capacitor can use separately, and the individual components that also can be used as in capacitance type potential transformer or capacitor voltage divider or the coupling capacitor is used.Its major function is tolerating high voltage, high voltage is divided into low voltage, ac filter, overvoltage protection etc.
But capacitor single-unit or more piece closed assembly use, and shell adopts bushing insulator usually, abbreviates the porcelain bushing type capacitor as.This porcelain bushing type capacitor has the following disadvantages:
1, Heavy Weight, light in structure are heavy, are unfavorable for lifting, transportation and installation.
2, flange mucilage binding weather-resistant property is relatively poor.Porcelain bushing adopts cement as adhesive, and porcelain spare, these two kinds of materials of cast iron flange are bonded together.Electroceramics, cement take place in ambient temperature under the situation of bigger variation, and the two produces contraction or expansion in various degree, thereby porcelain spare is caused inhomogeneous structural stress.In addition, cement easily absorbs airborne moisture and CO
2, particularly in the low temperature period, cement freezes after absorbing moisture, and volume increases, and compressing porcelain spare may cause porcelain bushing root phenomenon of rupture.
3, the outer surface insulation property are affected by environment big.When rainfall once in a while or light rain weather, there is continuous moisture film in the insulator surface of porcelain bushing, causes external insulation flashover easily.In addition, as porcelain bushing surface spraying PRTV, little and coating is thin because of the material wear-resistant intensity of PRTV own, the glaze adhesive strength of organic material PRTV and inorganic material porcelain bushing is not enough in addition, is easily corroded by dust storm, causes insulating sleeve surface contamination, causes flashover; The glaze of porcelain bushing may be corroded by dust storm under the extreme case, causes insulating sleeve water absorbent surface contamination, causes flashover.
4, explosion-proof, shockproof, impact resistance is relatively poor.Porcelain bushing can explode under the excessive grade of interior pressure extreme case, because porcelain bushing is fragile material, " flying porcelain " fragment after the blast can bring disaster to other electric equipments of periphery and personal security.
The utility model content
The purpose of this utility model is for overcoming the deficiencies in the prior art, and a kind of composite insulating material bushing type condenser is provided, and this capacitor is in light weight, flange mucilage binding weather-resistant property is good, the outer surface insulation property are strong, can not produce " flying porcelain " phenomenon, and convenient the installation and transportation.
The technical scheme that realizes the utility model purpose is:
A kind of composite insulating material bushing type condenser comprises capacitor body, unlike the prior art be: be provided with composite bushing at the capacitor body outer surface, be provided with capacitor packet and insulating material in the capacitor.
Also be provided with expander in capacitor, described expander is outer oily embedding structure or interior oily external structure, to compensate the insulating oil volume with variation of temperature.
Described insulating material is insulating oil or insulating gas.
Described composite bushing is the composite insulating material sleeve pipe.
Described capacitor packet is oil immersed type capacitor packet or the gas filled capacitor center after high vacuum.
But the utility model capacitor single-unit uses or the more piece closed assembly uses, to adapt to the insulating requirements of 35kV～1000kV electric power system.
The utility model has the advantages that: but the composite bushing antiultraviolet in this capacitor, anti-aging, anti-low temperature, windproof sand, the outer surface insulation property are stronger, and are in light weight, and flange mucilage binding weather-resistant property is better, explosion-proof, shockproof, impact resistance is stronger, and convenient the installation and transportation.

Structural representation when Fig. 2 is more piece composite insulating material bushing type condenser closed assembly.
Among the figure: 1. upper cover plate 2. expanders 3. composite insulating material sleeve pipe 4. capacitor packets, 5. insulating oils or insulating gas 6. lower covers.
Embodiment
Embodiment 1:
With reference to Fig. 1, a kind of composite insulating material bushing type condenser is made up of upper cover plate 1, expander 2, composite insulating material sleeve pipe 3, capacitor packet 4, insulating oil 5 and lower cover 6.Composite insulating material sleeve pipe 3 covers outside the capacitor, is provided with expander 2 and through the capacitor packet 4 of high vacuum in capacitor, and is filled with the insulating oil 5 of certain pressure.
This capacitor uses (as shown in Figure 2) for the more piece closed assembly.
Embodiment 2:
A kind of composite insulating material bushing type condenser, formed by upper cover plate 1, composite insulating material sleeve pipe 3, capacitor packet 4, insulating gas 5 and lower cover 6, outside capacitor, be provided with composite insulating material sleeve pipe 3, in capacitor, be provided with the capacitor packet 4 through high vacuum, and be filled with the insulating gas 5 of certain pressure.But this capacitor more piece closed assembly uses.
Above-described embodiment is the specific case that the purpose of this utility model, technical scheme and beneficial effect are further described only, and the utility model is not to be defined in this.All any modifications of within scope of disclosure of the present utility model, making, be equal to replacement, improvement etc., all be included within the protection range of the present utility model.
