Filed: 1990-11-22
Abstract: PURPOSE:To realize a circuit breaker with high breaking capacitance for which electromagnetic repulsion force is utilized in maximum, by making the reaction of a contact spring against electromagnetic repulsion force smaller in the process of dissociation of the second movable contact. CONSTITUTION:By the displacement of a torsion fulcrum of a contact spring 10 from the turning movement fulcrum 4 of the second movable contact 3, the length of an arm part 10a from the turning movement fulcrum 4 of the second movable contact 3 to the point of action of the spring force of the contact spring 10, is set to be getting smaller according to the turning movement of the second movable contact 3. Accordingly, as the second movable contact 3 dissocates more, the resistant force based on a contact spring 10 gets smaller. At the same time, torsion deformation angle of the contact spring 10 can be kept smaller than the turning angle of the second movable contact 3, and the resistant force can be made still smaller. Thus, dissocation of electromagnetic repulsion force can be made faster and improvement of breaking characteristics can be attempted.
