Abstract
The utility model discloses an epoxy resin poured composite voltage transformer used for performing electric energy metering and relay protecting in an electric power system, and the voltage transformer is composed of an iron core, high-voltage and low-voltage windings, a silicon rubber sleeve, an inner pouring body and a channel steel bracket; the iron core is coiled to be in a rectangle shape through a silicon sheet belt material, the section of the iron core is arranged to be in a four-stage step shape, the circular ring-shaped high-voltage and low-voltage windings are continuously wound on a core column of the rectangular iron core, the iron core, the high-voltage and low-voltage windings and high-voltage and low-voltage lead wires are wrapped and poured by epoxy resin so as to form the inner pouring body, the silicon rubber sleeve formed by pressing high-temperature vulcanizing silicone rubber is adhered on the outer surface of the inner pouring body through an adhesive, and the channel steel bracket is connected with the silicon rubber sleeve and the inner pouring body through bolts.
Description
Technical field
The utility model relates to a kind of compound voltage transformer of poured with epoxy resin of in electric power system, doing electric energy metrical and relaying protection use.
Background technology
At present, outdoor dry type voltage transformer product external insulation adopts outdoor pure epoxy resin to pour into a mould, and inner iron core adopts stacked; This kind voltage transformer exists cost high, and creepage distance is little, and no-load loss is big; Defectives such as temperature rise height; And the difficult control of casting process is prone to produce open defect, must carry out secondary and repair.
Summary of the invention
The purpose of the utility model is to provide the high poured with epoxy resin of a kind of cost performance compound voltage transformer, and not only creepage distance is big for it, the outward appearance zero defect, and no-load loss is little, hang down temperature rise, overload capacity is strong.
The utility model solves the technical scheme that its technical problem adopted: it is made up of iron core, high-low pressure winding, silicone rubber sleeve, interior pour mass, channel-section steel support five major parts; Iron core adopts silicon steel sheet band material to roll into rectangle; Its cross section divides level Four stepped arrangement; Continuous coiling goes out the high-low pressure winding of annular on the stem of rectangle iron core; Adopt indoor epoxy resin that iron core, high-low pressure winding and high-low pressure lead-in wire are sealed and pour into interior pour mass, the outer surface of interior pour mass is pasted the silicone rubber sleeve of going up by the high-temperature silicon disulfide rubber press forming with bonding agent, and the channel-section steel support is connected through bolt with interior pour mass with silicone rubber sleeve.
The purpose of the utility model also can further realize through following technical proposals.
Silicone rubber sleeve top is two upright high-voltage connection sleeve pipes that are respectively equipped with four alternate circular full skirts of size; The middle part is four identical oval full skirts; Its cross section is dihedral, and a square low-voltage lead terminal connections box is arranged at the bottom, and the side of terminal box is provided with the wiring of a circular metal waterproof and chews.
The beneficial effect of the utility model is, by the compound insulation system of poured with epoxy resin that silicone rubber sleeve and interior pour mass are formed, its production process is controlled easily, and no open defect need not be carried out secondary and repaired, and the more outdoor poured with epoxy resin product of cost is low.The full skirt that two high-voltage connection sleeve pipes in silicone rubber sleeve top and middle part are provided with respectively; Strengthened creepagely than distance, dielectric strength is high, is suitable for the heavy pollution area and installs and uses; The circular metal waterproof wiring of the square terminal box of silicone rubber sleeve bottom and terminal box side is chewed, and has concentrated wiring and water-proof function.
Iron core adopts high-quality silicon steel sheet band material to roll into rectangle continuously, and because of its no seam, there is not the air air gap of laminated core, magnetic circuit is closure fully; Magnetic leakage free; Can give full play to the grain orientation of silicon steel sheet, core section divides level Four stepped arrangement, and activity coefficient is high; Magnetic resistance and interlayer eddy current, short circuit have effectively been reduced, so product no-load loss is little, temperature rise is low, noise is little, anti-overload ability is strong.
