Abstract
The utility model relates to an ultrahigh voltage converter transformer ground shield end three-point shielding structure, belonging to the technical field of transformer manufacturing. The technical scheme includes that the shielding structure comprises ground shield paperboards (11, 12, 13, 14), paper-covered copper rods (1,2,3) and insulators (4,5,6,7,8), wherein the paper-covered copper rods are led out along the peripheries of the ground shield paperboard ends in a three-dimensional direction, and are grounded and fixed by the insulators. The shielding structure has simple structure and convenient installation, can effectively improve distribution of electric fields at the ends, corners and edges of the ground shield, leads the shape of equipotential to be smooth gradually and improves product safety greatly.
Description
Affiliated technical field:
The utility model relates to screen end, a kind of ultra high voltage converter transformer ground bikini shielding construction, belongs to technical field of transformer manufacturing.
Background technology:
Ground screen used in the high-voltage commutation transformer body all is an one point earth, its implementation method is to connect the shielding cardboard and draw ground connection with copper strips, this kind ground screen is simple in structure, be easy to realize, but there is screen end, ground electric field strength skewness, the equipotential line shape is not sufficiently oily, Given this weak points such as position, corner electric field strength is bigger, need shield end construction over the ground and improve.
The utility model content:
The utility model purpose provides screen end, a kind of ultra high voltage converter transformer ground bikini shielding construction, improves screen end, ground and position, corner field strength distribution, solves the problems referred to above that exist in the background technology.
The technical solution of the utility model is:
Ultra high voltage converter transformer ground screen end bikini shielding construction shield cardboard, paper bag copper rod, insulating part with comprising, along shield and shield three-dimensional border, cardboard end and draw many paper bag copper rods, paper bag copper rod ground connection is also fixed with insulating part.
Said along screen shielding three-dimensional border, cardboard end, ground, the front, back, left, right, up, down of shielding cardboard end with comprising.
Said paper bag copper rod radical is more than or equal to 3; Paper bag copper rod single-point or multipoint earthing, the earth point number is more than or equal to 1; Copper rod diameter 〉=φ the 5mm of paper bag copper rod, monolateral paper bag insulation thickness 〉=1mm.
The utlity model has characteristics simple in structure, easy for installation, and can effectively shield the Electric Field Distribution of end and corner with improving, make the equipotential line shape be tending towards slick and sly, significantly promote the product safety performance.
