The Body Structure And Working Motion Principle of Vacuum Circuit Breaker 2011-08-10
The main part of the framework, some of interrupter (vacuum bubbles), and actuator components. Body part by the conductive circuit breakers, insulation system, seals and housing components. Phase of the overall structure of the box. One conductive route back into the outlet conductive rod, into the outlet insulation bearing conductive clip, soft connection with the vacuum interrupter connected together. Agency for electric energy storage, electric sub-switch, but also has manual functionality. The entire structure by the closing spring, energy storage systems, over-current release, sub-closing coil, manual points closing system, auxiliary switches, storage instructions and other components. Work Vacuum Circuit Breakers use vacuum in zero current flow, the rapid spread and extinguish the plasma arc, cut off the current to complete the purpose. Action principle Energy storage process: When the charging motor 14 is powered, motor driven eccentric rotation, through the close of the eccentric wheel 10 to drive roller 9 and even knee arm swing plate 7, to promote energy storage swing pawl 6, the rotating ratchet 11, when the ratchet 11 with storage sleeve on the pin 32 positioned against the board after the two move together, so hang on the sleeve 32 in the energy storage spring 21 on the closing stretch. Storage sleeve 32 by the pins 13 fixed to maintain the storage state, while the energy storage sleeve on the knee arm 32 to promote electrical energy storage limit switch 5 off 14 power and energy storage pallet to be lifted, and the ratchet reliable detachment. Closing operation: When the agency received the closing signal (switch is off, the state has been energy storage), closing electromagnet 15 of the core being sucked downward, pulling positioning pieces 13 to rotate counterclockwise, lift storage to maintain, closing spring 21 to drive storage sleeve 32 counterclockwise rotation, the cam shaft cover 30 fixed pressure, driving with plate 29 and arm 27 movement, arm 27 fastened to axle 25, the agency is closing state. At this point, interlock 28 to lock positioning pieces, so that cattle can not be positioned counter-clockwise rotation, to achieve the purpose institution aggregators to ensure that the institutions in the closing position is not closing operation. Sub-gate operation: the circuit breaker switch, the sub-gate solenoid receives the signal, core pull, sub-gate release 19 of the mandrel upward movement, the tripping shaft 16 rotation, driven by the upward movement of ejector 18 , the top moving plate bending and drive axle 25 to 26 anti-clockwise. Solution with the rocker arm 27 axle 25 deducted, in the spring under the effect of sub-gate, complete the circuit breaker opening Operating Mechanism.
