Document Type and Number:
WIPO Patent Application WO/2017/161972
Kind Code:
A1
Abstract:
Provided are an interlocking device and a circuit breaker device; the interlocking device comprises a fixing plate (300), sandwiched between a first circuit breaker (100) and a second circuit breaker (200), and provided with a fastening structure used for fastening to a first circuit breaker (100) and/or a second circuit breaker (200); a slide plate (400), arranged on the fixing plate and may slide back and forth with respect to the fixing plate and is provided with a locking part (410); when the slide plate slides to a first preset position, the locking part limits the rotation of a first switch handle (110) and the locking part circumvents a second switch handle (210), allowing the second switch handle to rotate; when the slide plate slides to a second preset position, the locking part limits the rotation of the second switch handle and the locking part circumvents the first switch handle, allowing the first switch handle to rotate. The interlocking device is fastened to the circuit breaker directly by means of the fixing plate, without requiring the additional arrangement of a structural member used for fixing the interlocking device to the circuit breaker; thus the space required for mounting the interlocking device is reduced and the volume of the circuit breaker device is reduced.
