Operation principle of the present utility model is,
1) closing operation
When being manually pressed by the switch knob (or remote control provide switching signal) of intelligent controller 18, the master of intelligent controller 18
Through suitable time-delay, control circuit determines that connecting combined floodgate circuit after signal is effectively exports energy to the closing coil of permanent-magnet manipulating mechanism,
The internal magnetic field of permanent-magnet manipulating mechanism changes, when electromagnetic force be enough to the permanent magnetism retentivity offsetting separating brake stable state, and dynamic ferrum
Core stress disequilibrium, permanent-magnet manipulating mechanism moves to combined floodgate direction under the effect of electromagnetic force, passes through main shaft simultaneously and turns
Arm promotes insulated tension pole and moving conductive rod, completes the combined floodgate of vacuum switch.When arriving closing position, " conjunction position " is close
Switch provides signal, and closing circuit turns off, and the magnetic field that in magnetic circuit, only permanent magnet produces, now permanent magnetism retentivity makes permanent magnetism
Operating mechanism is maintained at " combined floodgate stable state ", and chopper is maintained at closing position.

Can controller 18 governor circuit through suitable time-delay determine signal be effectively followed by logical opening circuit to permanent-magnet manipulating mechanism point
Brake cable circle output energy, when electromagnetic field be enough to the permanent magnetism retentivity overcoming combined floodgate stable state, dynamic iron core is at electromagnetic force and contact
Under the effect of spring force, move to separating brake direction, pull insulated tension pole and moving conductive rod to complete very by the connecting lever on main shaft
The separating brake of empty switch, when arriving open position, " point position " proximity switch provides signal, and sub-gate circuit turns off, magnetic circuit
In magnetic field that only permanent magnet produces, now permanent magnetism retentivity makes permanent-magnet manipulating mechanism be maintained at " separating brake stable state ", open circuit
Device is maintained at open position.
3) error protection
When the charge circuit of chopper breaks down, fault-current signal is surveyed by the current transformer in insulation column 7
Arriving, send into intelligent controller 18, current signal is processed and identifies, when Cutoff current value is big by intelligent controller 18
When the protection value adjusted, intelligent controller 18 makes quick-break according to multiple or overcurrent protection selects, and prolongs accordingly
Separating brake instruction, chopper automatic brake separating, it is achieved error protection is sent time after；If electric current is less than protection definite value during time delay,
Intelligent controller 18 does not the most send out separating brake instruction, thus realizes shoving keeping away peak function.
4) manual brake separating
Separating brake handle ring 19 and manual brake separating handle 21, in case in case of emergency, pull isolation handle 13 by manpower
Realize manual brake separating.
5) reclosing operation
After chopper completes fault protection, automatic reclosing operation can be carried out by predetermined operation program；Intelligence control
The device 18 processed vacuum circuit breaker to being configured, can realize multiple shot reclosing and various faults protection by predetermined operation program.
