Abstract
The invention discloses a voltage divider casing pipe for an electronic type mutual inductor, which can be widely applied to the electronic type mutual inductor. The voltage divider casing pipe comprises a cylindrical glass fiber inner container, wherein a plurality of annular silicon rubber umbrella skirts are poured outside the glass fiber inner container; the silicon rubber umbrella skirts comprise major-diameter silicon rubber umbrella skirts and minor-diameter silicon rubber umbrella skirts; and the external diameter of each major-diameter silicon rubber umbrella skirt is more than that of each minor-diameter silicon rubber umbrella skirt, and the major-diameter silicon rubber umbrella skirts and the minor-diameter silicon rubber umbrella skirts are stacked at intervals. The voltage divider casing pipe for the electronic type mutual inductor has the advantages of small volume, light weight, convenient construction, no need of maintenance and difficult damage; the electric-field distribution of the surfaces of the silicon rubber umbrella skirts is uniform so as to increase flashover voltage greatly; and the hydrophobic nature of the silicon rubber umbrella skirts is good, and droplets formed by water on the surfaces of the silicon rubber umbrella skirts roll down quickly, so that the flashover voltage is increased greatly, and flashover is difficult to occur.
Description
Technical field
The present invention relates to a kind of power equipment, particularly relate to a kind of voltage divider sleeve pipe that is used for electronic mutual inductor.
Background technology
At present; in order to adapt to the power system development trend; metering and the needs of relaying protection to digitlization, microcomputerization and automation development; electronic mutual inductor slowly obtains promoting; as everyone knows; with the supporting voltage divider sleeve pipe that is provided with of electronic mutual inductor, traditional voltage divider sleeve pipe mostly is the casting of electroporcelain material one and forms the following shortcoming of ubiquity:
1) weight is big, and volume is big, and I﹠ M is extremely inconvenient;
2) damaged easily, the surface field skewness;
3) along with the going from bad to worse of environment, the pollution flashover on porcelain surface also often has generation, and probability of flashover increases along with the environment pollution level, the way that available increase is leaked than distance solves, but the increase of leaking than distance is limited, leaks ratio apart from big more, the sintering qualified rate of porcelain bushing is low more, and versatility is poor.
Summary of the invention
The object of the present invention is to provide a kind of electronic mutual inductor voltage divider sleeve pipe, it has in light weight, and volume is little, cracky not, and surface field is evenly distributed, and is difficult for taking place flashover, the characteristics that versatility is good.
The objective of the invention is to be achieved through the following technical solutions:
A kind of electronic mutual inductor voltage divider sleeve pipe is characterized in that, it comprises cylinder glass fiber inner bag, and described glass fibre inner bag is cast with the silicon rubber full skirt of most ring-types outward.
Described electronic mutual inductor has mounting flange with the bottom of voltage divider sleeve pipe, and described silicon rubber full skirt comprises big footpath silicon rubber full skirt and path silicon rubber full skirt, and the external diameter of described big footpath silicon rubber full skirt is greater than path silicon rubber full skirt, and between the two every stacking setting.
Beneficial effect of the present invention is, described electric electronic mutual inductor adopts the glass fibre inner bag with the voltage divider sleeve pipe, and the silicon rubber full skirt of the most ring-types of casting outside the glass fibre inner bag, not only volume is little, light weight, be convenient to construction, need not safeguard, cracky not, and the Electric Field Distribution on silicon rubber full skirt surface is more even, flashover voltage is improved a lot, and the hydrophobicity of silicon rubber full skirt is also fine, water form on its surface globule and very snap-roll fall, flashover voltage is improved greatly, be difficult for taking place flashover.
