Abstract
The invention relates to a tulip contact (10) for a gas-insulated circuit-breaker (1), comprising at least one contact section (12) having an inner contour (18) extending along a switching axis (X) between a tip (14) and a root (16), whereinthe inner contour (18) forms a contact throat at the tip (14) and exhibits a first radius (R1) in respect to the switching axis (X) that defines a narrowest cross section of the contact throat;the inner contour (18) comprises a first curved segment (C1) and, optionally, adjacent to the first curved segment (C1) a first straight segment (S1), at least one of the first curved segment (C1) and the first straight segment (S1) form the contact throat;the first curved segment (C1) exhibits a curving radius (RU) defining a convexity of first curved segment (C1) towards the switching axis (X) in a longitudinal sectional view; and1 ≤ RU/R1 and, optionally, RU/R1 ≤ 50.
