Described framework preferably adopts bakelite or strengthens nylon material and makes.
Described vacuum contactor comprises three vacuum switch tubes 21 along plumb line setting and a permanent magnet drive mechanism 22 be arranged on below vacuum switch tube, and permanent magnet drive mechanism drives the moving contact in three vacuum switch tubes to carry out divide-shut brake action; In addition in the present embodiment, moving contact 211 in each vacuum switch tube is positioned at below, fixed contact 212 is positioned at top, and each fixed contact protrudes upward the roof 11 of framework, and this part fixed contact stretching out framework roof directly uses as plug-in type mains side power connecting column 23, be also that three fixed contacts of three vacuum switch tubes are directly as mains side power connecting column; In the present embodiment, these three fixed contact alinements.
In concrete practice, also each mains side power connecting column and corresponding fixed contact split can be manufactured, but the two still adopts the structural design of the part that is connected, and is also feasible.
In the present embodiment, framework roof is also provided with the plug-in type load-side power connecting column 24 of three also alinement shapes, each load-side power connecting column all protrudes from framework roof, and each load-side power connecting column is connected with the moving contact of a corresponding vacuum switch tube respectively; In the present embodiment, three load-side power connecting columns and three mains side power connecting columns line up two straight lines, are preferably staggered.
Permanent magnet drive mechanism comprises rotating shaft and permanent magnet mechanism 221; Rotating shaft is arranged in the horizontal direction, and is positioned at the below of three vacuum switch tubes; Rotating shaft is provided with three contact springs and insulator, and by the moving contact of three guide posts along plumb line direction vertical drive three vacuum switch tubes; Two separating brake secondary springs rotating shaft support plate are equipped with, as the auxiliary power that separating brake is used; The output shaft of permanent magnet mechanism drives rotating shaft by connecting lever, and then synchronously drives three synchronous divide-shut brakes of vacuum switch tube by rotating shaft.
Wherein immediately below a load-side power connecting column, and between two vacuum switch tubes, and between framework roof and rotating shaft, be provided with an electronic changement; This electronic changement comprises motor 31, reversing interlock takes turns the gear assembly 33 that 32 and interlock motor output shaft and reversing interlock are taken turns; Reversing interlock wheel is exposed to a sidewall of framework; When two vacuum contactors use side by side, synchronous another vacuum contactor that drives of available this reversing interlock wheel realizes asynchronous separating brake, also two vacuum contactors are namely made always to be in different opening and closing states, one of them vacuum contactor is in "on" position, an other vacuum contactor just must be in gate-dividing state, thus guarantee security performance, effectively prevent two vacuum contactors and be in "on" position all simultaneously.
