  • Compact current transformer casing for gas-insulated switchgear assemblies
    Patent number: 7417847
    Abstract: The invention pertains to a current transformer (1?) for enclosed, gas-insulated high-voltage switchgear (10). According to the invention, a current transformer (1?) is characterized in that a removable installation flange (12, 12?) is provided on a fill opening (3c) of the core carrier (11) for one-piece current transformer cores (2). Among other things, embodiments pertain to: a removable installation flange (12, 12?) in the form of a two-part clamping flange (12) or in the form of a one-piece rotary flange (12?) that is screwed on the fill opening (3c) similar to a bayonet catch. Among other things, the attained advantages are: radially increased installation space for one-piece current transformer cores (2); reduced diameter (d) for one-piece current transformer cores (2) and reduced structural volume of the current transformer casing (11a).
