Abstract

The invention discloses a duplex bidirectional interlocking mechanism of a switch cabinet, relates to the metal-enclosed switchgear, and aims to provide the duplex bidirectional interlocking mechanismof the switch cabinet for realizing automatic interlocking of a circuit breaker handcart and a metering handcart in the switch cabinet and ensuring to satisfy the "five prevention" interlocking requirement of the switch cabinet by solving the technical problems; and the duplex bidirectional interlocking mechanism is simple in structure and reliable, convenient to mount and maintain, high in universality and low in manufacturing cost. For solving the technical problems, a technical scheme is adopted as follows: a first locking apparatus (4) comprises a first cantilever (6) arranged on a secondplane and a first baffling rod (7) hinged with the first cantilever (6); and a first bolt (8) which passes through a first through hole and can come in and go out of a first accommodating space and afirst contact (9) which can extend into a second accommodating space are arranged at the two ends of the first baffling rod (7) respectively.

Description
