Abstract
The utility model relates to the technical field of insulations in high-voltage electric appliances, in particular to a voltage equalizing shielding cylinder of a porcelain bushing conductor. The voltage equalizing shielding cylinder comprises a cylinder body arranged at the lower part in a porcelain bushing; the lower part of the cylinder body is connected to a lower flange and the external side of a central conductor by bolts and have gaps with both the central conductor and the porcelain bushing; an arc flange is arranged on the internal side of the upper part of the cylinder body along a cylinder opening; and the external side of the cylinder opening is an arc transitional plane without a sharp corner. The voltage equalizing shielding cylinder of the porcelain bushing conductor, provided by the utility model, has a simple structure and has the characteristics of improving electric field distribution and improving insulating property in the porcelain bushing.
Description
Technical field
The utility model relates to insulation technology field in a kind of High-Voltage Electrical Appliances, specifically a kind of all pressures shielding cylinder of insulator conductor.
Background technology
Insulator is used the extensive of ten minutes in electric power system and electric equipment, it is as the container that insulate in a kind of electrical equipment, and insulation exempts from the influence of surrounding environment factor in making.Along with electric pressure increases, internally the requirement of insulation is also increasingly high, and the field strength distribution of perfect condition is uniform; Potential distribution is linear, but actual conditions are not so, near insulator lower flange place the time; Field intensity increases suddenly, and is inhomogeneous along the vertical Potential distribution of insulator.Because the inhomogeneities of Electric Field Distribution is comparatively outstanding between center conductor and insulator lower flange, especially in filthy serious area, the phenomenon that discharge takes place here is more, causes insulation property to reduce.
Summary of the invention
The utility model provides a kind of simple in structure in order to overcome above-mentioned defective, improves Electric Field Distribution, improves all pressures shielding cylinder of the insulator conductor of insulation property in the insulator.
The technical scheme that the utility model adopts is: a kind of all pressures shielding cylinder of insulator conductor; Comprise cylindrical shell; Described cylindrical shell is arranged on insulator inside below, the bottom of cylindrical shell through screw be connected on the lower flange, the outside of center conductor, and and center conductor and insulator between all gapped; Described cylindrical shell upper inner is provided with the flange of arc along nozzle, and the outside of said nozzle is the arc transiting surface of no wedge angle.
The utility model is provided with shielding cylinder on lower flange; This shielding cylinder is between insulator and center conductor, and this position is the position that insulator inside is easy to generate non-uniform electric most, and this shielding cylinder becomes the coaxial cylindrical electric field with the rod-plate shape electric field of insulator lower end; Be improved along insulator field strength distribution inhomogeneities; Potential distribution is also near the linear character of the rational faculty, and the Electric Field Distribution that the utility model is balanced has improved the insulation property of insulator.
Description of drawings
Fig. 1 is the sketch map of the utility model.
Embodiment
Combine accompanying drawing that the utility model is further described at present; Fig. 1 is a kind of embodiment of the utility model; Comprise cylindrical shell 1, described cylindrical shell 1 is arranged on insulator 2 inner belows, and the bottom of cylindrical shell 1 is connected on the lower flange 3 through screw; Cylindrical shell 1 is arranged on the outside of center conductor 4 simultaneously, and is all gapped between cylindrical shell 1 and center conductor 4 and the insulator 2.Usually the endoporus of the interior hole dimension of cylindrical shell 1 and lower flange 3 is measure-alike.Described cylindrical shell 1 upper inner is provided with the flange of arc along nozzle, and the outside of said nozzle is the arc transiting surface of no wedge angle.
The cylindrical shell 1 of the utility model is installed on the lower flange 3; And between insulator 2 and center conductor 4, this position is the position that insulator 2 inside are easy to generate non-uniform electric most, and shielding cylinder has shielded the contact-making surface of insulator 2 with lower flange 3; Rod-plate shape the electric field of insulator 2 lower ends is become the coaxial cylindrical electric field; The curved flanges of shielding cylinder top nozzle has the good shielding and the effect of uniform electric field, makes along insulator 2 field strength distribution inhomogeneities to be improved, and Potential distribution is also near the linear character of the rational faculty; The Electric Field Distribution that the utility model is balanced has improved the insulation property of insulator 2.
The utlity model has simple in structurely, improve Electric Field Distribution, improve the characteristics of insulation property in the insulator.
