Description
Technical field
The utility model relates to a kind of circuit breaker, particularly a kind of permanent magnet mechanism.
Background technology
Operating mechanism is as the core of primary cut-out, and its point, combined floodgate characteristic directly affect reliability and the mechanical property of primary cut-out.Operating mechanism is divided into electromagnetic mechanism, spring mechanism and permanent magnet mechanism by its principle, and wherein permanent magnet mechanism is few with parts, structure simple, high reliability receives increasing concern.According to the requirement of national grid intellectualized reconstruction, permanent magnet mechanism circuit-breaker is power switch first-selected after intelligent grid transformation, and three-phase separate vertical permanent magnet mechanism circuit breaker is the new direction of permanent magnet mechanism circuit-breaker research.Bulk power grid meeting survey data shows, the circuit breaker failure of about 60% is operating mechanism fault, therefore the requirement of three-phase separate vertical permanent magnet mechanism's breaker safe and stability to be reached, the permanent magnet mechanism that just must make reasonable in design and mechanical performance is safe and reliable.Permanent magnet mechanism circuit-breaker drive rod is connected with vacuum interrupter by linkages such as connecting levers, and mechanical structure is more complicated.
Utility model content
The purpose of this utility model is to provide a kind of novel breaker permanent magnet mechanism, simplifies its structure, reduces cost, and easy to use and reliable.
The purpose of this utility model is achieved in that a kind of novel breaker permanent magnet mechanism, comprise setting dynamic iron core in the enclosure, magnet exciting coil, magnet ring and permanent magnet is provided with between described dynamic iron core and shell, described magnet ring and permanent magnet are positioned at below magnet exciting coil, described permanent magnet is arranged on the skin of magnet ring, described dynamic iron core directly connects the moving conductive rod in arc control device through insulating bar, the drive rod section of stretching out of dynamic iron core is arranged with stage clip, one end of described stage clip is connected with drive rod end, and the other end of stage clip is conflicted on shell.
Compared with prior art, the beneficial effects of the utility model are, dynamic iron core of the present utility model directly connects the moving conductive rod of arc control device side by insulated tension pole, structure is comparatively simple, there is provided confining force when open position by precompressed stage clip, have permanent magnet to provide confining force during closing position, this device simplifies permanent magnet mechanism and arc control device syndeton, reduce cost, and use convenient.The utility model can be used in primary cut-out.
In order to make the utility model installation and maintenance convenient, the end thread of described drive rod is connected with nut, is arranged with back-up ring inside nut, conflicts on back-up ring in one end of described stage clip, and the other end of stage clip is conflicted on shell.
