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).
