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 used in a kind of high-tension apparatus shelf depreciation, withstand voltage test, particularly a kind of inflatable high voltage grading ring of measuring transformer shelf depreciation.
Background technology
High voltage grading ring is the important utility appliance in high-voltage test, need as requested in high-tension apparatus shelf depreciation, withstand voltage test at the scene, at high-voltage terminal, high voltage grading ring is installed, but due to voltage levels high-tension apparatus needed for comparatively large, the heavier-weight of grading ring volume, cause deposit and communications and transportation is inconvenient, in-site installation not easily with the problem such as bushing damage.
Summary of the invention
One inflation assembly type high voltage grading ring provided by the invention, solves the larger Heavy Weight of volume that existing grading ring exists and deposits 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 fixedly installed bushing shell for transformer on the transformer, be provided with army cap on the top of bushing shell for transformer, army cap will be socketed with metal abutment ring, the upper surface of metal abutment ring is respectively arranged with three upper screwed holes at equal intervals radian, the lower surface of metal abutment ring is respectively arranged with three lower threaded holes at equal intervals radian, conducting ring on hardware cloth is provided with directly over metal abutment ring, on hardware cloth conducting ring lower surface on be respectively arranged with three top nuts at equal intervals radian, one end and the top nut of upper stud bolt are screwed together, the other end and the upper screwed hole of upper stud bolt are screwed together, conducting ring under hardware cloth is provided with immediately below metal abutment ring, under hardware cloth conducting ring upper surface on be respectively arranged with three lower nuts at equal intervals radian, one end and the lower nut of lower stud bolt are screwed together, the other end of lower stud bolt is together with lower screw hole, conducting ring is provided with hardware cloth embedded on charging connector, under hardware cloth, conducting ring is provided with embedded lower charging connector.
Charging connector is provided with movable hardware cloth upper cover on embedded, embedded lower charging connector is provided with movable hardware cloth lower cover, and described bushing shell for transformer is high voltage side of transformer sleeve pipe or step down side sleeve pipe.
The present invention utilize can the metal ring securing member of assembly and disassembly and inflatable conductive ring shape object with the use of solve voltage levels grading ring build super large, ultra-wide to such an extent as to deposit transport inconvenient, the problem not easily and easily causing bushing to damage is installed, this inflatable high voltage grading ring is mainly used in all pressing in high voltage shelf depreciation, withstand voltage test temporarily, shielding, due to very light in weight, reduce sleeve pipe load-bearing, sleeve pipe loss percentage will be reduced; Its specification all can realize from 110kV ~ 1000kV.
