Description
Technical field
The utility model relates to power distribution automation equipment, more specifically, relates to outdoor 10KV permanent magnetism vacuum circuit-breaker.
Background technology
The present three domestic permanent magnetism vacuum circuit-breakers function that do not link basically, this just causes in actual use owing to frequent use, external environment, particularly do reclosing function etc. and cause the capacitor charging not in place, causes three permanent magnetism individual events very likely to cause the danger of phase shortage! If can't imagining of this phenomenon can cause electrical network and user's very big economic loss.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, to provide a kind of three permanent magnet mechanisms of realizing to divide the pole-mounted circuit breaker of resultant motion synchronously.
The purpose of this utility model is achieved in that a kind of pole-mounted circuit breaker, comprise the mainframe box housing, the top of mainframe box housing connects three vertical insulation pouring bodies that are provided with, three vertical permanent magnet mechanisms that are provided with are set in the mainframe box housing, three permanent magnet mechanisms are separately positioned on the below of corresponding insulation pouring body, the separating brake screw rod vertically is set respectively in each permanent magnet mechanism, the sluice separating spring nut that is threaded respectively on each separating brake screw rod, each permanent magnet mechanism is nested with tripping spring outward respectively with separating brake screw rod between the corresponding sluice separating spring nut; Spline spindle of horizontally set in the described mainframe box housing, spline spindle is arranged on the below of three permanent magnet mechanisms, one end of spline spindle is supported on the mainframe box housing, and the other end of spline spindle is supported on the spline spindle seat, and the spline spindle seat is fixedlyed connected with the bottom of mainframe box housing; The lower end of every separating brake screw rod is a fixedly connected drive block respectively, and the two ends of drive block are hinged one respectively and connect connecting lever, and the other end of each connection connecting lever is fixedlyed connected with spline spindle respectively.
The utility model is by above design, and the separating brake screw rod of each permanent magnet mechanism individual event is by drive block and connect connecting lever and connect with same spline spindle, realized three functions that link then.After having added the three-phase link gear, the phase shortage phenomenon is just avoided fully, three permanent magnetism individual events linked (perhaps with divide or with closing) can the situation of phase shortage not appear.The utility model has improved the coefficient safe in utilization of outdoor three permanent magnetism vacuum circuit-breakers greatly, has avoided the generation of the open-phase fault of circuit breaker.
The fixedly connected indicator board fixed mount in the bottom of mainframe box housing of the present utility model is hinged the divide-shut brake indicator board on the indicator board fixed mount, on the mainframe box housing of divide-shut brake indicator board below form is set; Fixedly connected indicator board connecting lever on the described spline spindle, an indicator board connecting lever and an indicator board connecting rod are hinged, and the other end of described indicator board connecting rod and described divide-shut brake indicator board are hinged.The rotation of the drive splines main shaft that moves up and down by permanent magnet mechanism, the rotation by spline spindle drives the indicator board connecting lever and rotates, and the indicator board connecting lever drives the rotation that the indicator board connecting rod promotes the divide-shut brake indicator board again and shows divide-shut brake.
Spline spindle of the present utility model is set in outside the mainframe box housing away from an end of spline spindle seat, fixedly connected separating brake handle on the external spline spindle of chassis shell, one side of separating brake handle is provided with the divide-shut brake direction board, and the divide-shut brake direction board is fixedly connected on the mainframe box housing.Owing to separating brake handle and spline spindle interlock, the rotation of spline spindle drives the separating brake handle and rotates simultaneously, thereby realizes the Presentation Function of divide-shut brake.
In order to make connection connecting lever and spline spindle better fixing, spline is set on the spline spindle, on each connection connecting lever the projection that matches with spline is set respectively.
