Embodiment
Below the utility model is described in further detail:
embodiment 1
The one intelligence vacuum circuit breaker that the present embodiment provides, structure as shown in Figure 1, the casing 2 comprising pedestal 1 and be arranged on pedestal, casing 2 both sides are respectively equipped with input terminal 3 and outlet terminal 4, casing outside is provided with fender bracket 5, the upper cover 12 at casing top is provided with boom hoisting 6, switching-in spring 9 is provided with in casing, energy-storage system 8, overcurrent release 7 and divide-shut brake coil, also be provided with manual divide-shut brake system outside casing to be connected with overcurrent release, input terminal is accessed by casing side and is connected with overcurrent release one end, overcurrent release upper end is connected with energy-storage system by switching-in spring, the other end of overcurrent release is connected with vacuum interrupter 10, the other end of vacuum interrupter is connected with outlet terminal 4, instrument transformer 11 is provided with in the outside of vacuum interrupter and outlet terminal link, install intelligent controller in casing, intelligent controller is connected with remote control equipment by 26 core aviation sockets, and intelligent controller collection signal is connected with divide-shut brake coil, controls the energy storage of switching-in spring and release energy by divide-shut brake coil.
The energy-storage system of the present embodiment comprises Manual stored energy organization and electric energy-stored mechanism, and Manual stored energy organization is that manual pressure arm and energy storage sprocket wheel are formed, and drives the energy storage of energy storage chain wheel drive switching-in spring by manual pressure arm; Electric energy-stored mechanism comprises motor and chain, by motor by chain drive energy storage sprocket wheel.
The course of work of the present embodiment is:
(1) thermal energy storage process
Electric energy-stored principle: output torque is passed to the energy storage sprocket wheel of mechanism by motor, through chain drive, drive connecting lever to rotate, make switching-in spring energy storage, when connecting lever upperpush rod pushes travel switch, cut off motor power, spring energy-storage is complete.
Manual energy storage principle: pull manual pressure arm down with hand or high-voltage insulating rod, the pinion on lead agency output shaft, passes to the energy storage sprocket wheel fully engaged with it by rotation torque, thus drives connecting lever to rotate, and makes switching-in spring energy storage.
(2) sub-switching operation
Electronic separating brake principle: after mechanism receives sub-gate signal, the dynamic iron core of tripping electromagnet moves upward, thus the de-bar of promotion moves upward, and makes the constraint release between separating brake semiaxis and separating brake pallet.Meanwhile, separating brake pallet rotates counterclockwise by roller compressing, and multijaw connecting lever is rotated counterclockwise, so complete sub-switching operation because of the thrust by tripping spring.
Manual brake separating principle: pull manual deciliter handle down with hand or high-voltage insulating rod, when separating brake semiaxis is rotated counterclockwise, multijaw connecting lever is rotated counterclockwise, and drives separating brake pallet to rotate simultaneously, produces and operate same effect with tripping electromagnet.
(3) overcurrent tripping operation: when the drop-away current specified passes through the coil in overcurrent tripping, electromagnet action, push rod pushes release lever, makes the constraint release between separating brake semiaxis and separating brake pallet, thus generation operates identical effect with tripping electromagnet, makes the action of circuit breaker overcurrent tripping.
(4) closing operation
Electric switch-on principle: after mechanism receives switching signal, the dynamic iron core of making electromagnet moves upward, thus promotion release lever moves upward, and makes the constraint release between combined floodgate semiaxis and combined floodgate pallet.Meanwhile, combined floodgate pallet rotates counterclockwise by the compressing of roller, and release energy storage state, the convergent force due to switching-in spring makes cam be impacted, and knocks the multijaw connecting lever on output shaft, completes closing operation.
Closing by hand principle: pull manual deciliter handle down with hand or high-voltage insulating rod, when separating brake semiaxis is rotated counterclockwise, multijaw connecting lever is rotated counterclockwise, and drives separating brake pallet to rotate simultaneously, produces and operate same effect with making electromagnet.
Reclosing operation: after the energy of mechanism's release energy-stored spring, complete closing operation, in "on" position, after mechanism completes stored energy operation again, mechanism is in "on" position, and in this state once after receiving correct signal, mechanism just can realize an automatic reclosing operation.
The controller of the present embodiment has coincidence, looped network function.Function is selected as being set as " coincidence ", and controller is pressed automatic circuit function and performed protection, and overcurrent overlaps, unsuccessful reclosing locking; When function is selected to be set as " looped network ", looped network function action pressed by controller.Controller is furnished with GPRS(or CDMA) communication module; achieve radio communication function; when after be short-circuited by load side fault or single phase ground fault; controller disconnects vacuum circuit-breaker device automatically; controller uploads fault and switch changed position event information automatically to Surveillance center while performing protection act.Controller and Switch main body are electrically connected by control cables and aerial plug-in unit, realize its protection and automatic monitoring function.
Above embodiment is only and technological thought of the present utility model is described; protection range of the present utility model can not be limited with this; every technological thought according to the utility model proposes, any change that technical scheme basis is done, all falls within the utility model protection range.
