Abstract

The invention discloses an assembly inflatable high voltage equalizing ring which aims to solve the problem that a current voltage equalizing ring with larger size is inconvenient to transport. The equalizing ring provided by the invention is characterized in that a metal connection ring (4) is sleeved with a propeller cap (3); a metal cloth above conducting ring (5) is arranged right above the metal connection ring (4); three upper nuts (11) are respectively arranged on the lower surface of the metal cloth above conducting ring (5) at uniformly-spaced radian; one ends of upper double-head bolts (7) are in threaded connection with the upper nuts (11), and the other ends are in threaded connection with upper threaded holes (8); a metal cloth below conducting ring (6) is arranged under the metal connection ring (4); three lower nuts (12) are respectively arranged on the upper surface of the metal cloth below conducting ring (6) at uniformly-spaced radian; one ends of lower double-head bolts (10) are in threaded connection with the lower nuts; and embedded upper inflatable nozzles are uniformly arranged on the metal cloth below conducting ring. The equalizing ring is suitable for high voltage partial discharge and voltage resistance test.

Description

A kind of inflation assembly type high voltage grading ring
Technical field
The present invention relates to the device that uses in a kind of high-tension apparatus shelf depreciation, the withstand voltage test, particularly a kind of inflatable high voltage grading ring of measuring transformer shelf depreciation.
Background technology
The high voltage grading ring is the important utility appliance in the high-voltage test, need the high voltage grading ring be installed at high-voltage terminal as requested in high-tension apparatus shelf depreciation, the withstand voltage test at the scene, but because the required grading ring volume of the high-tension apparatus of voltage levels is big, weight is heavier, causes and deposit and communications and transportation inconvenience, the on-the-spot installation are difficult for and problems such as bushing damage.
Summary of the invention
A kind of inflation assembly type high voltage grading ring provided by the invention has solved that the big Heavy Weight of volume that existing grading ring exists is deposited and the technical matters of communications and transportation inconvenience.
The present invention overcomes the above problems by the following technical programs:
A kind of inflation assembly type high voltage grading ring, comprise transformer, be set with bushing shell for transformer at transformer, be provided with army cap on the top of bushing shell for transformer, army cap is being socketed with the metal abutment ring, on the upper surface of metal abutment ring, uniformly-spaced be respectively arranged with three upper screwed holes radian, on the lower surface of metal abutment ring, uniformly-spaced be respectively arranged with three following threaded holes radian, directly over the metal abutment ring, be provided with conducting ring on the hardware cloth, on the lower surface of conducting ring on the hardware cloth, uniformly-spaced be respectively arranged with three top nuts radian, one end of last stud bolt is screwed onto with top nut, the other end of last stud bolt is screwed onto with upper screwed hole, be provided with conducting ring under the hardware cloth under the metal abutment ring, under hardware cloth, uniformly-spaced be respectively arranged with three lower nuts on the upper surface of conducting ring radian, one end of following stud bolt is screwed onto with lower nut, the other end of following stud bolt is screwed onto with following threaded hole, on the hardware cloth conducting ring be provided with embedded on charging connector, conducting ring is provided with embedded down charging connector under the hardware cloth.
Charging connector is provided with movable hardware cloth loam cake on embedded, and embedded charging connector down is provided with movable hardware cloth lower cover, and described bushing shell for transformer is transformer high-voltage side sleeve pipe or step down side sleeve pipe.
To such an extent as to but the metal ring securing member of utilization assembly and disassembly of the present invention and inflatable conductive ring shape object are used voltage levels grading ring build super large, the super wide problem that transportation is inconvenient, installation is difficult for and causes easily the bushing damage of depositing of having solved, this inflatable high voltage grading ring is mainly used in all pressing temporarily, shielding in high voltage shelf depreciation, the withstand voltage test, because very light in weight, reduce the sleeve pipe load-bearing, will reduce the sleeve pipe loss percentage; Its specification all can realize from 110kV~1000kV.
