Abstract
The invention relates to an emergency switch-off module of a breaker. The emergency switch-off module comprises a push rod, an L-shaped plate and a switch-off tripping linkage element, wherein an outer side wall of a switch cabinet horizontally extends into the switch cabinet, the L-shaped is hinged on the switch cabinet and comprises a side plate and a bottom plate, the side plate is arranged at the rear side of the push rod, and the bottom plate is arranged at the upper side of the switch-off tripping linkage element. The invention aims to provide a high-stability emergency switch-off module of the breaker, and by the high-stability emergency switch-off module, the breaker can be rapidly switched off when the switch cabinet is at a close state. The invention has the advantages that emergency switching off of the breaker is achieved by matching among the push rod, the L-shaped plate and the switch-off tripping linkage element, the breaker can be switched off through pressing the push rod by an operator when the switch cabinet is at the close state, and the emergency switch-off module is high in safety; and moreover, the switch-off tripping linkage element directly acts on a switch-off tripper of the breaker, a fault is difficult to occur, and high stability is achieved.
Description
Technical field
The present invention relates to a kind of circuit breaker emergency opening assembly.
Background technology
Switch cubicle is a kind of electric equipment, and Main Function carries out generating electricity in electric power system, transmits electricity, in the process of distribution and electric energy conversion, carries out folding, control and protection power consumption equipment.Work as line failure, when needing to carry out emergency opening to the circuit breaker in switch cubicle, first separating brake should be carried out by electronic separating brake switch, if electronic separating brake switch failure or locking, to carry out emergency opening in the opening button then needing to act on circuit breaker panel by connecting rod, because connecting rod acts in opening button, be that one indirectly operates, easily there is the faults such as button useless, cause emergency opening failure.
Summary of the invention
The circuit breaker emergency opening assembly that the object of the present invention is to provide a kind of stability high, it can realize fast and reliable separating brake circuit breaker under switch cubicle closes door state.
Object of the present invention is achieved through the following technical solutions: circuit breaker emergency opening assembly, it comprise by switch cubicle lateral wall extend horizontally to inside switch cabinet pushing ram, be articulated with L shaped plate on switch cubicle and separating brake dropout STATEMENT OF FEDERALLY SPONSORED; Described L shaped plate comprises the side plate be positioned on rear side of pushing ram and the base plate be positioned on the upside of separating brake dropout STATEMENT OF FEDERALLY SPONSORED.
Compared to prior art, the invention has the advantages that: the present invention is by coordinating the emergency opening realizing circuit breaker between pushing ram, L shaped plate and separating brake dropout STATEMENT OF FEDERALLY SPONSORED, operating personnel just can realize breaker open operation by pressing pushing ram under switch cubicle closes door state, and fail safe is high; And separating brake dropout STATEMENT OF FEDERALLY SPONSORED acts directly in the separating brake dropout of circuit breaker, and fault is less likely to occur, and stability is high.
