Abstract

The present invention relates to medium-voltage gas circuit breakers, and more precisely to an electric shunt and method of transitioning an electric contact between a fixed contact to an auxiliary contact of an electric shunt. The invention discloses an electric shunt comprising: a shunt body (1), a fixed contact (2), an auxiliary contact (3), a returning means (4), wherein the fixed contact (2) is mounted on the shunt body (1), and the auxiliary contact (3) is movably coupled with the shunt body (1) such that the auxiliary contact (3) is able to move slidably in a guideway (6) of the shunt body (1) between a first position (A) and a second position (B), wherein in the first position (A) a distance between the auxiliary contact (3) and the fixed contact (2) is the smallest, and in the second position (B) the distance between the auxiliary contact (3) and the fixed contact (2) is the greatest, wherein the returning means (4) are coupled with the shunt body (1) and the auxiliary contact (3) such that the returning means (4) are biasing the auxiliary contact (3) toward the second position (A). The invention discloses a method of transitioning an electric contact between a fixed contact to an auxiliary contact of an electric shunt designed in accordance with the disclosure.
