Fig. 3 is seen in
, and Fig. 3 triggers electromagnet 5 and comprises housing 52 for triggering electromagnet 5 sketch mapes; One end of housing 52 is fixed with yoke plate 53; The other end is fixed with first magnetic pole 56, is fixed with second magnetic pole, 55, the first magnetic poles, the 56 middle iron cores 57 that are equipped with slidably on the yoke plate 53; Push rod 51 1 ends movably are located on unshakable in one's determination 57; The other end stretches out from second magnetic pole 55 slidably, between 57 and second magnetic pole 55 unshakable in one's determination spring 58 is housed, and between housing 52 and yoke plate 53 and around first magnetic pole 56, second magnetic pole 55 and iron core 57, solenoid 54 is housed on every side.
like Fig. 1, can be known: the tripping mechanism 2 that is installed on the bearing 4 comprises amplification tripping force device 21, dropout plate 22, resetting device 23 and extension spring 24; Amplify tripping force device 21 and be positioned at dropout plate 22 tops, resetting device 23 resets and amplifies tripping force device 21, and extension spring 24 1 ends connect dropout plate 22, and the other end connects bearing 4, dropout plate dropout operating mechanism.
like Fig. 5, described amplification tripping force device 21 comprises housing 213, and an end of housing 213 is fixed with cover plate 215; Guide post 216 is fixed on the cover plate 215; Dropout push rod 211 1 ends slidably stretch out from housing 213, and the other end slidably is enclosed within on the guide post 216, and compression spring 214 is housed between dropout push rod 211 and guide post 216; Locking rod 212 rotatable being contained on the housing 213, torsionspring 217 is installed between locking rod 212 and the housing 213.
are owing to pass through locking rod 212 release dropout push rods 211 at above-mentioned amplification tripping force device 21.After the release, apply downward pressure by 214 pairs of dropout push rods 211 of compression spring, thus the output tripping force.In above-mentioned process, the pulling force that pull bar 14 transmits is not converted into tripping force, thereby can set tripping force through compression spring 214, makes it satisfy actual needs.
are like Fig. 6,7; Described dropout plate 22 comprises the dropout end 221 of the circuit breaker operation mechanism that is used to thread off; The two hub setting ends 222,223 of hub setting on bearing 4, the mating holes 224 that cooperates with resetting device 23, the fixedly fixing hole 225 of extension spring 24 1 ends; First lock chamber 226, second lock chamber 227, described first lock chamber 226 and second lock chamber 227 are provided with up and down.
separating brake blocking mechanism 3 comprises deadlock lever 31 and the stage clip 32 between deadlock lever 31 and bearing 4.
like Fig. 4, described deadlock lever 31 comprises operating side 312, installing hole 311, locked end 313; Described installing hole 311 passes through the installation shaft hub setting on bearing 4; Thereby locked end 313 cooperates locking dropout plate 22 with above-mentioned first lock chamber 226 and second lock chamber 227; Operating side 312 is used for after pressed by external force; It can make deadlock lever 31 overcome stage clip 32 rotation and perk locked ends 313, thus the locking of 31 pairs of dropout plates 22 of release deadlock lever.
When external comprehensive protection device received over-current signal, external comprehensive protection device sent the instruction of threading off
, triggered electromagnet 5 and got electronic work, and push rod 141 ejects; Promote to hit end 13, make rotating shaft 12 rotations, thereby the locking rod 212 that drives pull bar 14 pullings amplification tripping force device 21 rotates; Releasing is to the locking of dropout push rod 211, and dropout push rod 211 ejects under the effect of compression spring 214, promotes dropout plate 22 to lower swing; And the action of trigger action mechanism for implementing separating brake, after 22 rotations of dropout plate put in place, deadlock lever 31 rotated under the effect of stage clip 32; And get into second lock chamber 227, and prop up dropout plate 22, prevent its answer.Behind the operating mechanism separating brake, the main shaft of circuit breaker drives resetting device 23 actions, and resetting device 23 will amplify dropout push rod 211 jack-up of tripping force device 21, makes compression spring 214 be returned to compressive state.Because the locking action of 31 pairs of dropout plates 22 of deadlock lever makes operating mechanism be in gate-dividing state, and can't implement closing operation.
If the locking to dropout plate 22 is removed in the operating side 312 of pressing deadlock lever 31, dropout plate 22 is replied under the effect of extension spring 24, and releasing is to the locking of operating mechanism, just can make the operating mechanism can reclosing
