Abstract

The device comprises phase modules mounted on metal base (1), inside which drives with magnetic latch (2, 3, 4), synchronizing (6) and interlock (7) shafts, block contacts are situated. The phase modules comprise supporting insulators (9), with vacuum chambers (10) positioned inside, contact terminals (11, 12) and traction insulators (14). Shapes of traction insulator (14) and immovable insulation tubular fragment (16) provide labyrinth air gap between the contact terminals and the base, increasing electrical strength of the clearance. When the circuit breaker operates, resilient conductive spirals (17) roll in the annular clearance between terminal (11) and movable contact bush (18), providing multiple-point contact of high conductivity. Drive magnetic systems (2, 3) constitute two bowl-shaped component parts made of high - coercivity material. The contact terminals are produced of an extrusion profile. Manual deenergization generator (20) is implemented as an independent magnetic system, which, when disconnecting, generates a current pulse, and electrically connected with drive coils (4). Remote indicator of main contact positions (19) is connected with the mechanism of synchronizing shaft with the flexible connection in the form of encapsulated wire cable. Socket contact separators (23) are made of aluminum alloy using extrusion process.
