Abstract
A dry insulation capacitor voltage transformer includes a capacitive voltage divider closed in an insulation shell, a slug and an electromagnetic device constituted by a high-voltage capacitor. The top end of the shell has a primary terminator and the lateral side of the lower shell is provided with an outlet box. In addition to the above components, other space inside the closed insulation shell is filled with solid insulating materials. The utility model has the advantages of: 1) adopt solid insulation, with no oil or no gas, no seepage or leakage hidden trouble and reliable insulation; 2) no environment pollution hidden trouble, fire and pollution hidden trouble; 3) the solid insulating material volume has no larger change because of temperature change, guarantees insulation effect, and the design saves an expander component and decreases cost, compared with a crude oil immersed capacitor voltage transformer and a gas insulated capacitor voltage transformer; 4) no need of consideration about oil or gas leakage, reduced shell sealing requirements, simplified manufacture process and decreased cost; 5) easy equipment maintenance and prolonged equipment service life.
Description
(1) technical field
The utility model relates to the capacitance type potential transformer that uses in a kind of high pressure or the ultrahigh voltage power power transmission and transformation system, and is particularly a kind of in the capacitance type potential transformer of formula insulation.
(2) technical background
What generally use at present is the oil immersed type capacitance type potential transformer.Be full of insulating oil in the seal casinghousing of this kind capacitance type potential transformer, calutron and capacitor voltage divider all are immersed in the insulating oil.Expander is housed in the housing, is used to compensate insulating oil and varies with temperature the change in volume that causes, make the limited pressure that keeps regulation in the housing.Its weak point one is the hidden danger that has insulating oil leakage, if seepage takes place, not only influences its built-in electrical insulation, also can cause environmental pollution; The 2nd, in case the inner electrical breakdown fault that takes place, insulating oil will decompose, its volume will expand rapidly above the limit of compensation of expander, powerful pressure can make case fragmentation, jeopardize personnel's and equipment safety on every side, and flammable insulating oil overflows the high temperature of back during electrical breakdown and makes it burning, very easily causes fire.
Chinese patent CN2472323 " gas-insulated capacitance type potential transformer " is at solving the problem that the oil immersed type capacitance type potential transformer exists.But the leakage of insulating gas is to be difficult to the thoroughly difficult problem of solution.Gas leakage influences its insulation effect, also causes environmental pollution.In order to prevent gas leakage strict to housing seal processing, the product cost of raising.
(3) utility model content
The purpose of this utility model is a kind of dry insulation capacitance type potential transformer of design, adopts solid insulation, does not have oil, no gas, does not have the hidden danger of seepage or leakage.Simplified manufacturing process, cost reduces.
The dry insulation capacitance type potential transformer of the utility model design comprises the capacitor voltage divider of the insulation shell that places sealing, fuse and the calutron that high-voltage capacitance is formed, and the housing top is a terminal, and outlet box is equipped with in the lower housing portion side.Except that said elements was installed, other space was full of solid insulating material in the insulation shell of sealing.
The utility model has the advantages that: 1, adopt solid insulation, do not have oil, no gas, do not have the hidden danger of seepage or leakage, insulation is reliable; 2, the hidden danger of non-environmental-pollution and potential safety hazard on fire, blast; 3, the solid insulating material volume can not guarantee insulation effect because of variations in temperature has bigger change, and therefore the design has omitted dilator element than former oil immersed type capacitance type potential transformer and gas insulated electro appearance formula voltage transformer, reduces cost; 4, need not to consider the leakage of oil or gas, so housing seal requires to reduce simplified manufacturing process, cost decline; 5, be easy to maintenance of equipment, prolong service life of equipment.
(4) description of drawings
The general structure schematic diagram of the dry insulation capacitance type potential transformer that Fig. 1 designs for the utility model.
(5) embodiment
As shown in Figure 1, this dry insulation capacitance type potential transformer comprises the capacitor voltage divider 1 of the upper body 2 that places the sealing insulation, fuse 3 that high-voltage capacitance is formed and at the calutron 6 of the lower case 5 of sealing insulation, upper body 2 tops are a terminal 8, and outlet box 4 is equipped with in lower case 5 sides.Lower house 2,5 is interior except that said elements is installed in the insulation of sealing, and other space is full of solid insulating material 7.
After in lower case 5, calutron 6 being installed, reserve the device wiring,, make the gaps in the lower case 5 be full of insulating material 7 with insulating material 7 vacuum pourings.There is insulation processing mouth 9 on the top of upper body 2.Upper body 2 is tightly connected with lower case 5, and fuse 3 and capacitor voltage divider 1 are installed.The wiring of calutron 6 is connected with upper element through encapsulation process.From 9 vacuum pourings of insulation processing mouth, make the gap in the upper body 2 be full of insulating material 7 with insulating material.
Thermoplasticity or the heat cured insulation macromolecular material of above-mentioned insulating material for solidifying, refer to mylar, or polyvinyl resin, or acrylic resin, or epoxy resin, or silica gel, or any two or two or more mixtures in the mylar, polyvinyl resin, acrylic resin, epoxy resin, silica gel.
