Description
Technical field
The utility model relates to a kind of high-tension current inductor, does not especially have the outdoor type Dry Type High Tension Current Transformer of oil gas.
Background technology
The structure of the high-tension current inductor that on high-voltage fence, uses at present mainly contains two kinds: positive power formula and inverted, and for the electrical network more than the 220kv, the positive power formula of domestic use glue is many; Positive power formula is simple in structure; Be easy to make, but dynamic thermal stability is poor, inverted advantage is that a winding is short; Its dynamic thermal stability is good, and therefore the use to inverted type current transformer has become trend.
Summary of the invention
The problem that the utility model will solve provides a kind of inverted high-tension current inductor, to overcome the defective of positive power formula high-tension current inductor.
In order to address the above problem, the utility model is realized through following technical scheme.
A kind of outdoor type Dry Type High Tension Current Transformer of the utility model, its structure comprises winding one time, secondary winding and iron core combination; EHT cage, insulating barrier, insulated tube; Full skirt, secondary winding fairlead, potting resin; Said secondary winding and iron core combination place the head of current transformer, and a said winding passes from the center of secondary winding and iron core combination.The periphery of said secondary winding fairlead and secondary winding and iron core combination is enclosed with insulating barrier; Installed an EHT cage additional in the outside of said insulating barrier; Said EHT cage lower end is connected with insulated tube; Said potting resin is used for filling the excess room of insulated tube, and said full skirt is bonded on the sidewall of insulated tube.
The further improvement of the utility model is: comprise in the said insulating barrier that length and position are the ground electric screen that gradually changes, middle electric screen and high pressure electric screen form the equal laminated structure of capacitor type, and this structure is fixedly installed in the insulated tube.Top is the high pressure electric screen, and the middle part is middle electric screen, and the bottom is the ground electric screen.
The further improvement of the utility model is: said full skirt adopts silastic material to make; Said insulated tube adopts fiberglass insulating tube; Said potting resin adopts epoxide resin material, is used for filling the excess room of insulated tube, and a said winding adopts copper pipe, copper rod or copper bar to make.
The utility model adopts inverted structure, without oil gas, has avoided the danger of breaking out of fire, and dynamic thermal stability is good and be convenient to maintenance, thereby is accepted by market.
