The invention will be further described in conjunction with the accompanying drawings and embodiments again for the below.
Embodiment
Accompanying drawing 1 has provided the cutaway view of the embodiment of the invention at gate-dividing state.
All insulation vacuum circuit breaker polar among Fig. 1 comprises pole housing 1, upper terminals 2, vacuum interrupter 3, silastic cord breaker 4, lower terminals 5, insulated tension pole 6; Terminals 3.1 and upper terminals 2 are connected by screw fastening on the arc control device of vacuum interrupter 3, and terminals 3.7 and lower terminals 5 are connected by screw fastening under the arc control device of vacuum interrupter 3, and the pull bar of vacuum interrupter 3 is connected with described insulated tension pole 6; Be provided with a plurality of conducting rings 3.8 in the vacuum interrupter 3, be assemblied in the annular recess 3.9 of terminals 3.7 inner surfaces under the arc control device, connect terminals 3.7 under moving conductive rod 3.6 and the arc control device; Be provided with insulated connecting piece 3.11 between moving conductive rod 3.6 in vacuum interrupter 3 and the pull bar 3.12.
Among the present invention, vacuum interrupter 3 comprises terminals 3.1 on the arc control device, upper ceramic case 3.2, radome 3.3, fixed contact 3.4, moving contact 3.5, moving conductive rod 3.6, terminals 3.7 under the arc control device, a plurality of conducting rings 3.8, lower ceramic case 3.10, insulated connecting piece 3.11, pull bar 3.12, bellows 3.13, the inner surface of terminals 3.7 arranges a plurality of annular recess 3.9 under the arc control device; The airtight insulation system of vacuum interrupter 3 is comprised of terminals 3.7, lower ceramic case 3.10, bellows 3.13 under terminals on the arc control device 3.1, upper ceramic case 3.2, the arc control device, and the conducting system of vacuum interrupter 3 is comprised of terminals 3.7 under terminals on the arc control device 3.1, fixed contact 3.4, moving contact 3.5, moving conductive rod 3.6, conducting ring 3.8, the arc control device; Because moving conductive rod 3.6 and insulated connecting piece 3.11 are encapsulated in the vacuum environment, pull bar 3.9 is not connected electric with moving conductive rod 3.4, and described pull bar 3.12 is connected with insulated tension pole 6, and pull bar 3.12 and insulated tension pole 6 are not charged.
