Title:
ARCLESS BREAKING DEVICE OF CONTACTOR, CONTACTOR, AND ARCLESS BREAKING METHOD
Document Type and Number:
WIPO Patent Application WO/2018/086366
Kind Code:
A1
Abstract:
An arcless breaking device of a contactor, a contactor, and an arcless breaking method. The contactor comprises a first stationary contact (11), a second stationary contact (12), and a first movable contact (13). The arcless breaking device comprises: a bidirectional triode thyristor (14), a T1 end of the bidirectional triode thyristor (14) being disposed corresponding to a first sub-contact (16) of the second stationary contact (12), and a T2 end of the bidirectional triode thyristor (14) being disposed corresponding to a second sub-contact (18) of the second stationary contact (12); and a spring (19) having one end fixedly connected to the first movable contact (13) of the contactor and the other end connected to a G end of the bidirectional triode thyristor (14). The first stationary contact (11) and the second stationary contact (12) are connected by a wire. When a control end of the contactor is powered on, the first stationary contact (11) contacts the first movable contact (13) for electric conduction; when the control end of the contactor is powered off, a voltage generated by a contact resistance at which the first stationary contact (11) and the first movable contact (13) are disconnected is applied across the T1 end and the G end and across the Ti end and the T2 end of the bidirectional triode thyristor (14) by the spring (19), the wire, and the second stationary contact (12). The breaking device and the breaking method solve the technical problem that an arc easily occurs to a contactor.
