Abstract
The utility model discloses a vertical type oiled paper insulation current transformer, which comprises an oil tank, a device body formed by combining a primary winding and a secondary winding, a high voltage insulation sleeve, a primary wiring terminal, a secondary wiring board and an expander. An end screen grounding terminal is arranged on the secondary wiring board, and an end screen is fixed on the secondary wiring board in the oil tank. The vertical type oiled paper insulation current transformer effectively solves the problem that end screen dielectric loss is changed through influence of weather humidity, and provides powerful guarantee for correct judgment of product insulating properties. In addition, the vertical type oiled paper insulation current transformer omits ceramic members required by single lead-out of the end screen, reduces manufacturing cost, and avoids problems of seal leakage, thereby effectively guaranteeing reliability of product performance.
Description
Technical field
The utility model relates to a kind of high-tension current inductor, and being specifically related to a kind of rated voltage that is applicable to is the just vertical paper oil insulation capacitive current transformer in 110kV and the above electrical network.
Background technology
High-tension current inductor is one of electric equipment important in the project of transmitting and converting electricity, and the high-tension current inductor that China uses in 110kV and above electrical network is main with paper oil insulation capacitor type instrument transformer mainly.The paper oil insulation capacitive current transformer generally merges grow up to be a useful person body, high-tension insulating bushing, primary connection terminal, secondary connection plate and expander etc. by fuel tank, winding and secondary winding and forms.Traditional paper oil insulation current transformer; The end screen is drawn separately through little porcelain spare; But the end screen is situated between to decrease and changed greatly by the weather humidity effect, and correct judges that the product insulation property affect, though at present porcelain spare is become the alumina porcelain material; When but ambient humidity was big, end screen Jie damage value changed still greatly.
The utility model content
The utility model is to the problem that exists in the background technology; Designed a kind of just vertical paper oil insulation current transformer; Purpose is: adopt the end to shield and directly be connected on the secondary connection plate from fuel tank internal, decrease the problem that receives the weather humidity effect and change thereby effectively solve end screen Jie.
The technical solution of the utility model:
A kind of just vertical paper oil insulation current transformer; Comprise device body, high-tension insulating bushing, primary connection terminal, secondary connection plate and expander that fuel tank, winding and secondary winding are merged into; It is characterized in that: said secondary connection plate is provided with end screen earth terminal, and shield at the fuel tank internal fixation on the secondary connection plate at the end.
Said secondary connection plate adopts the more excellent cast-type structure of humidity resistance.
Said end screen is fixed through holding screw with the secondary connection plate.
The beneficial effect of the utility model:
The utility model efficiently solves end screen Jie and decreases the problem that receives the weather humidity effect and change, and correct judges that the product insulation property provide strong guarantee.In addition, the design has practiced thrift last screen and has drawn required porcelain spare separately, has reduced manufacturing cost, and has avoided the sealing leakage of oil problem brought thus, thereby has effectively guaranteed the reliability of properties of product.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the partial enlarged drawing of secondary connection plate among Fig. 1.
Embodiment
Describe the utility model in detail below in conjunction with accompanying drawing.
Shown in Fig. 1 to 2; A kind of paper oil insulation high-tension current inductor; Comprise expander 1, primary connection terminal 2, high-tension insulating bushing 3, device body 4, fuel tank cap 5, fuel tank 6, secondary connection plate 7 and secondary connection box 8, secondary connection plate 7 is provided with end screen earth terminal 9.The end screen is fixed on the secondary connection plate 7 through nut 10 in fuel tank 6; Secondary connection plate 7 outsides connect end screen earth terminal 9 with ground strip; Ground connection is shielded at the end, and the end screen is closed in the secondary connection box 8, decrease the problem that receives the weather humidity effect and change thereby effectively solved last screen Jie.
To sum up the utility model accomplishes the end in view.
