The operation principle of tripping mechanism of closing a floodgate in the combined floodgate trip gear of the operating mechanism of the present embodiment is as follows:
Energy-stored spring 517 energy storage of spring operating mechanism is complete → under the pulling force effect of energy-stored spring 517, close spring pull bar to move downward → close the retaining pin 516 that spring pull bar pulls energy storage ratchet 515 to be rotated counterclockwise → to install on energy storage ratchet 515 and turn clockwise press against combined floodgate pallet 512 → combined floodgate pallet 512 on dropout roller will be pressed in the right lock bolt swing arm 5132 of combined floodgate lock bolt 513, make combined floodgate lock bolt 513 be rotated counterclockwise → due to the restriction of locking bearing pin 524, combined floodgate lock bolt 513 cannot be rotated counterclockwise, so far, switch-on latching is realized;
After receiving order of closing a floodgate, making electromagnet 514 is charged and start excitation, lance on making electromagnet 514 is subject to electromagnetic force, with dropout part 5141 towards combined floodgate lock bolt 513 move → after lance and dropout part 5141 arrive certain speed, to left lock bolt swing arm 5131 impingement area of combined floodgate lock bolt 513 impact → after combined floodgate lock bolt 513 is subject to this impulsive force, destroy the original snap close balance of combined floodgate lock bolt 513, combined floodgate lock bolt 513 is made to turn clockwise (when combined floodgate lock bolt 513 turns clockwise, so far just achieved to close a floodgate and threaded off) → due to after combined floodgate lock bolt 513 turns clockwise, no longer carry out spacing to combined floodgate pallet 512, combined floodgate pallet 512 also turns clockwise, no longer carry out spacing → ratchet 515 to ratchet 515 to be rotated counterclockwise with cam 5210 axle and cam 5210, realize closing operation.
In combined floodgate trip gear, the operation principle of locking device is as follows:
After switch-on latching, the spacing bearing pin 5133 of isolating closing lock device has been put into below the right-hand member of combined floodgate lock bolt 513, restriction combined floodgate lock bolt 513 clockwise movement, thus maintained switch-on latching state, circuit breaker cannot be closed a floodgate at all, thus realizes isolation circuit breakers to be latched in open position state.
In the control circuit of force motor 527 after locked loop to locking order → locked loop in the charged adhesive of locking contact device, its contact adhesive in motor 527 loop, make the charged rotation of force motor 527 → by single gear mechanism driving, force rotating shaft 521 rotates → transmission crank arm 529 and then force rotating shaft 521 rotate together → driven by connecting rod 523, locking bearing pin 524 is under the straight-line guidance effect of combined floodgate support 518, carry out tandem motion, insert in combined floodgate tripping mechanism, right lock bolt swing arm 5132 bottom of restriction combined floodgate lock bolt 513 → when locking bearing pin 524 moves to locked position of coupler, control cam 5210 and push down locking travel switch 522 → be held down due to locking travel switch 522, its contact in locked loop becomes normally opened contact, locked loop dead electricity (simultaneously, the unblock travel switch 5213 separating lock loop is not held down, it becomes normally-closed contact separating the contact in lock loop, after auxiliary switch 5212 also follows force rotating shaft 521 to rotate to locked position of coupler, auxiliary switch 5212 contacting, carries out signal output.) → due to locked loop dead electricity, locking contact device dead electricity, its contact in control circuit is opened, and motor 527 stalls → block action is terminated;
Separate in the control circuit of force motor 527 lock loop receive unlock command after → separate the charged adhesive of locking contact device in lock loop, its contact adhesive in motor 527 loop, make the charged reverse rotation of force motor 527 → by single gear mechanism driving, force rotating shaft 521 reverse rotations → transmission crank arm 529 and then force rotating shaft 521 reverse rotation together → driven by connecting rod 523, locking bearing pin 524 exits combined floodgate tripping mechanism, no longer limit right lock bolt swing arm 5132 bottom of combined floodgate lock bolt 513 → when locking bearing pin 524 moves to unlocked position, control cam 5210 to push down and unlock travel switch 5213 → be held down owing to unlocking travel switch 5213, it becomes normally opened contact separating the contact in lock loop, separate lock loop dead electricity (simultaneously, the locking travel switch 522 of locked loop is not held down, its contact in locked loop becomes normally-closed contact, after auxiliary switch 5212 also follows force rotating shaft 521 to rotate to unlocked position, auxiliary switch 5212 contacting, carries out signal output.) → owing to separating lock loop dead electricity, separates latch contact dead electricity, and its contact in control circuit is opened, and motor 527 stalls → unlocking motion is terminated.
In this enforcement, locking device can be directly installed in the spring operating mechanism of normal circuit breaker, without the need to changing the structure of spring operating mechanism, inserted the combined floodgate support 518 of spring operating mechanism by the locking pivot pin on locking device, the motion of restriction combined floodgate lock bolt 513 realizes the mechanical latching to isolated circuit breaker.The isolating closing lock system that this locking device realizes has reliability, fail safe, integration, versatility advantages of higher, can be locked in open position by the isolated circuit breaker closing of Reliable guarantee, realize locking position.
