Force-applying bracket 5211 is mainly by the base plate being fixed in frame and erect the left riser on base plate and right riser is constituted, left riser and right riser are respectively supported at the left and right end positions of force rotating shaft 521, and are convexly equipped with the block spacing convex shoulder at the opposite side of left riser and right riser respectively at the two ends, left and right of force rotating shaft 521.The right-hand member of force rotating shaft 521 passes from right riser, passes and part upper connection has the padlock direction board 528 indicating transmission crank arm 529 swing position.Force motor 527 is fixed on position above force rotating shaft 521, the right side of right riser, the output shaft of force motor 527 passes on right riser, the part that passes of output shaft is connected on the periphery of force rotating shaft 521 by single gear transmission mechanism, and the driving gear 525 being connected on output shaft in single gear transmission mechanism is bigger than the driven gear 526 being connected in force rotating shaft 521.Transmission crank arm 529 is in the left side of driven gear 526.Locking travel switch 522 and unblock travel switch 5213 are each attached on the right flank of left riser, and positioned opposite before and after the contact site of locking travel switch 522 and unblock travel switch 5213.Control cam 5210 and be in locking travel switch 522 and the position unlocked between travel switch 5213.Auxiliary switch 5212 is in the left side of left riser, and is fixed in the left side edge of base plate by the mounting seat arranged on the right side of it.
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 move downward → close spring pull bar pull energy storage ratchet 515 rotates counterclockwise → on energy storage ratchet 515, the retaining pin 516 of installation will bear against in the right lock bolt swing arm 5132 of combined floodgate lock bolt 513 by press against the dropout roller that combined floodgate pallet 512 turns clockwise → close a floodgate on pallet 512, make combined floodgate lock bolt 513 rotate counterclockwise → due to the restriction of locking bearing pin 524, combined floodgate lock bolt 513 cannot rotate counterclockwise, so far, it is achieved switch-on latching；
nullAfter receiving combined floodgate order，Making electromagnet 514 is charged and starts excitation，Lance on making electromagnet 514 is by electromagnetic force，With dropout part 5141 towards combined floodgate lock bolt 513 move → after lance and dropout part 5141 arrive certain speed，Left lock bolt swing arm 5131 impingement area of combined floodgate lock bolt 513 is impacted → closes a floodgate lock bolt 513 by after this impulsive force，Destroy combined floodgate lock bolt 513 original snap close balance，Combined floodgate lock bolt 513 is made to turn clockwise (when combined floodgate lock bolt 513 is turned clockwise，The most just having been achieved with close a floodgate thread off) → turn clockwise due to combined floodgate lock bolt 513 after，No longer combined floodgate pallet 512 is carried out spacing，Combined floodgate pallet 512 also turns clockwise，No longer ratchet 515 is carried out spacing → ratchet 515 to rotate counterclockwise with cam 5210 axle and cam 5210，Realize closing operation.
In combined floodgate trip gear, the operation principle of blocking 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, limit combined floodgate lock bolt 513 clockwise movement, thus maintained switch-on latching state, allow chopper cannot be carried out closing a floodgate at all, thus realize being latched in isolation circuit breakers open position state.
nullIn the control circuit of force motor 527 locked loop to after 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 → and transmission crank arm 529 and then force rotating shaft 521 rotated 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 is (simultaneously，The unblock travel switch 5213 solving lock loop is not held down，Its contact in solving lock loop becomes normally-closed contact；After auxiliary switch 5212 also follows force rotating shaft 521 to rotate to locked position of coupler, auxiliary switch 5212 contacting, carry out signal output.) → due to locked loop dead electricity, locking contact device dead electricity, its contact in control circuit is opened, and makes motor 527 stalls → block action terminate；
nullAfter in the control circuit of force motor 527, solution lock loop receives unlocking command → solve 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 reversely rotates → and transmission crank arm 529 and then force rotating shaft 521 reversely rotated 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 → when locking bearing pin 524 moves to unlocked position of combined floodgate lock bolt 513，Control cam 5210 and push down unblock travel switch 5213 → be held down owing to unlocking travel switch 5213，Its contact in solving lock loop becomes normally opened contact，Solve 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, carry out signal output.) → owing to solving lock loop dead electricity, solves latch contact dead electricity, and its contact in control circuit is opened, and makes motor 527 stalls → unlocking motion terminate.
In this enforcement, blocking device can be directly installed in the spring operating mechanism of normal circuit breaker, without the structure of spring operating mechanism is changed, inserted the combined floodgate support 518 of spring operating mechanism by the locking pivot pin on blocking device, the motion limiting combined floodgate lock bolt 513 realizes the mechanical latching to isolated chopper.The isolating closing lock system that this blocking device realizes has reliability, safety, integration, versatility advantages of higher, it is possible to the isolated circuit breaker closing of Reliable guarantee is locked in open position, it is achieved position locks.
