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