Title:
CIRCUIT BREAKER CONTACT SYSTEM AND CIRCUIT BREAKER
Document Type and Number:
WIPO Patent Application WO/2017/186061
Kind Code:
A1
Abstract:
A circuit breaker contact system and a circuit breaker, comprising: a contact support; a rotary support shaft; a busbar; a plurality of conductive sheet groups, each conductive sheet group comprising two or three conductive sheets, each conductive sheet being provided with a contact, and the plurality of conductive sheet groups being arranged in parallel and rotatably supported on the contact support by means of the rotary support shaft, so that the plurality of contacts form a contact surface that can contact an external conductor to achieve electric conduction; and a flexible connecting piece, two ends of which are respectively electrically connected with the plurality of conductive sheets and the busbar. A first gap is formed between two adjacent conductive sheet groups, a second gap is formed between two adjacent conductive sheets in each of the conductive sheet groups, and the first gap is larger than the second gap; contacts on the conductive sheets at two sides of the conductive sheet group are disposed distant from each other and deflected in the arrangement direction of the conductive sheets. A condition that a contact pressure between the conductive sheets and the external conductor is decreased due to overheated fusion welding of the contacts is avoided.
