Function of the present utility model includes:
1) energy storage
Needed for breaker closing, energy is provided by switching-in spring 10 energy storage, and energy storage both can be driven by external power source Galvanic electricity machine completes, it is possible to use energy accumulation handle manually completes.
Stored energy operation: carried out by the energy storage motor 16 being fixed on framework, or energy accumulation handle is inserted In manual energy storage hole, shake is carried out counterclockwise.Chain is driven to realize by motor output shaft 15 time electric energy-stored Transmission, drives chain to realize transmission by worm gear-endless screw (11,13) during manual energy storage.Energy storing drive When sprocket wheel 23 rotates, pin rod 2 promotes the slide block 4 on energy storage transmission wheel 6 to make energy storage axle 7 follow rotation And carry out energy storage by connecting lever 1 and connecting lever 2 21 stretching switching-in spring 10.When arriving energy storage position, Slide block 4 depressed by gag lever post 3 on framework makes energy storage axle 7 disengage with chain gear transmission, and energy storage keeps pallet 9 Withstanding roller 8 and keep energy storage position, the connecting plate 1 on energy storage axle drives energy storage direction board 25 simultaneously Flip displays " energy storage " labelling and switch auxiliary switch cut off energy storage motor 16 power supply, this Time chopper be in combined floodgate SBR.
2) close a floodgate
In closing operation, no matter pressing " combined floodgate " button with hands or remote operation makes making electromagnet Action, all makes energy storage holding shaft 19 rotate, and makes energy storage keep pallet 9 to unclamp roller 8, combined floodgate bullet Spring 10 shrinks and makes the cam 1 on energy storage axle 7 and axle rotate by two connecting levers (5,21) simultaneously, Cam 1 drive link mechanism again (34,36,37,38,39) drives insulated tension pole 33 and moves Contact enters closing position, and compresses disc spring 32, keeps contact pressure needed for contact.
Feed motion closes a floodgate after completing and keeps pallet 38 and Rocker arm 41 to keep closing position, energy storage simultaneously Direction board, energy storage auxiliary switch reset motor current supply circuit are connected.If external power supply is also connected, again Entering energy storage state, a deciliter direction board connecting plate 44 pulls a deciliter direction board, demonstrates the labelling of " conjunction ", Transmission connecting plate pulls master subswitch to switch.
Note: when chopper be in "on" position or select blocking device and do not make blocking device unlock and Handcart type breaker, in advancing push, all can not carry out closing operation.
3) separating brake
Both " separating brake " button can have been pressed, it is possible to make manual brake separating push rod 42 He by connecting external power source Tripping electromagnet 40 (separating brake release electromagnet or overcurrent tripping electric magnet) action makes combined floodgate keep pallet 38 unlock with Rocker arm 41 and realize sub-switching operation.The energy stored by disc spring 32 and tripping spring 35 makes Dynamic and static contact in vacuum interrupter 28 separates.At separating brake process back segment, hydraulic bjuffer absorb Separating brake process dump energy also limits separation point position, a deciliter direction board connecting plate 44 pull a deciliter direction board Demonstrate the labelling of " dividing ", pull enumerator, it is achieved rolling counters forward simultaneously, transmission connecting plate draw Dynamic master subswitch switching.
Seeing Fig. 3, Fig. 4, the anti-misoperation setting of this utility model chopper and function be,
1) interlocking of the combined floodgate in interlocking mechanism 17 bent plate 51 is correspondingly arranged with combined floodgate bent plate 52, open circuit After device closing operation completes, the combined floodgate interlocking bent plate 51 in interlocking mechanism 17 moves downward and clasps combined floodgate Combined floodgate bent plate 52 in holding shaft, can not again close a floodgate when the non-separating brake of chopper, see Fig. 3.
2) separating brake for a certain reason after breaker switching-on operation, if reclosing command is always maintained at, Circuit breaker internal anti-jump control loop will cut off closing circuit, prevent multiple shot reclosing.
3) interlocking bent plate 53 is correspondingly arranged with the pin 54 on combined floodgate bent plate 52, handcart type breaker When not arriving testing position or operating position, interlocking bent plate 53 clasp the pin on combined floodgate bent plate 52 54, cut off closing circuit simultaneously, prevent chopper to be in "on" position and enter loading zone, see Fig. 3.
4) handcart type breaker is after closing a floodgate in operating position or testing position, by interlocking mechanism 17 Interlocking roller 55 pushes down propelling jam plate 56 so that handcart will be unable to mobile, prevents from advancing in "on" position Or pull-out loading zone, see Fig. 4.
5) if selecting electric closing locking, in the case of not making blocking device unlock, closing operation is stoped.
Chopper of the present utility model meets GB 1984-2003 " high-voltage AC breaker ", JB 3855-1996 " 3.6~40.5kV indoor AC ", DL/T 403-2000 " 12~40.5kV high-pressure vacuum breaker order technical conditions " standard-required, and meet The related request of IEC62271-100:2001.
