The invention will be further described in conjunction with the accompanying drawings and embodiments more below.
Embodiment
Fig. 1 illustrates the cutaway view of the embodiment of the present invention at gate-dividing state.
Full insulation vacuum breaker polar post 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; Be provided with multiple conducting ring 3.8 in vacuum interrupter 3, be assemblied in the annular recess 3.9 of terminals 3.7 inner surface under arc control device, connect terminals 3.7 under moving conductive rod 3.6 and arc control device; Insulated connecting piece 3.11 is provided with between moving conductive rod 3.6 in vacuum interrupter 3 and pull bar 3.12.
In the present invention, 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, terminals 3.7 under arc control device, multiple conducting ring 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 multiple annular recess 3.9; The airtight insulation system of vacuum interrupter 3 is made up 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 made up 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 3.12 be not electrically connected with moving conductive rod 3.6, and described pull bar 3.12 is connected with insulated tension pole 6, pull bar 3.12 and insulated tension pole 6 not charged.
The high-voltage charged body of vacuum interrupter 3 of the present invention is sealed in pole completely, completely isolated with outside air, make vacuum interrupter from the impact (as height above sea level, atmospheric pressure and filth, air themperature, humidity, salt fog etc.) of external environment, full insulation vacuum breaker polar post is not subject to external environment influence when circuit breaker runs.
Motion analysis is as follows: because 3.12 one, pull bar is connected with insulated tension pole 6, other end is connected with insulated connecting piece 3.11, when driving insulated tension pole 6 to move upward, pull bar 3.12 moves upward, moving contact 3.5 moves upward, moving conductive rod 3.6 along be assemblied in terminals under arc control device annular recess conducting ring inside upward sliding, when moving contact contacts with fixed contact, lower terminals realize conducting by terminals on terminals, conducting ring, moving conductive rod, moving contact, fixed contact, arc control device under arc control device and upper terminals, and circuit breaker realizes closing function.Otherwise when insulated tension pole moves downward, moving contact is separated with fixed contact, realize separating brake function.
