The utility model is described in further detail in conjunction with the accompanying drawings and embodiments more below.
Embodiment
Accompanying drawing 1 has provided the cutaway view of the utility model embodiment at gate-dividing state.
All insulation vacuum circuit breaker polar in Fig. 1 comprises pole housing 1, upper terminals 2, vacuum interrupter 3, silastic cord breaker 4, lower terminals 5, insulated tension pole 6; On the arc control device of vacuum interrupter 3, terminals 3.1 are connected by screw fastening with upper terminals 2, and under the arc control device of vacuum interrupter 3, terminals 3.7 are connected by screw fastening with lower terminals 5, and the pull bar of vacuum interrupter 3 is connected with described insulated tension pole 6; In vacuum interrupter 3, be provided with a plurality of conducting rings 3.8, be assemblied in the annular recess 3.9 of terminals 3.7 inner surfaces under arc control device, connect terminals 3.7 under moving conductive rod 3.6 and arc control device; Between moving conductive rod 3.6 in vacuum interrupter 3 and pull bar 3.12, be provided with insulated connecting piece 3.11.
In the utility model, vacuum interrupter 3 comprises terminals 3.1 on arc control device, upper ceramic case 3.2, radome 3.3, fixed contact 3.4, moving contact 3.5, moving conductive rod 3.6, under arc control device, terminals 3.7, a plurality of conducting rings 3.8, lower ceramic case 3.10, insulated connecting piece 3.11, pull bar 3.12, bellows 3.13, under arc control device, the inner surface of terminals 3.7 arranges a plurality of annular recess 3.9; 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 arc control device 3.1, upper ceramic case 3.2, arc control device, and the conducting system of vacuum interrupter 3 is comprised of terminals 3.7 under terminals on arc control device 3.1, fixed contact 3.4, moving contact 3.5, moving conductive rod 3.6, conducting ring 3.8, arc control device; Because moving conductive rod 3.6 and insulated connecting piece 3.11 are encapsulated in 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.
