So that no matter being locked in the isolation knife that isloation state is in conjunction state；When breaker main shaft B34 reversely rotate into
When row breaker open operation, locking connecting lever B39 opposite direction rotation, so that junction panel B40 is detached from the first isolation swing arm B8 to release
Locking.
Wherein, the breaker closing accumulating mechanism can use the combined floodgate accumulating mechanism or other of existing on-pole switch
Existing accumulating mechanism, in the present embodiment, the Storage Unit includes that breaker closing pawl B21, breaker closing turn round column
B20, transmission mechanism and cam；The transmission mechanism include active rotating shaft B33 and driven spindle B22, the active rotating shaft B33 and
The both ends of driven spindle B22 are rotatablely connected with front panel and rear panel B13 respectively, and the cam is fixed on driven spindle B22(quilt
Driven gear wheel B27, which is blocked, to be not shown) on, driver pinion B32 is fixed on active rotating shaft B33, on driven spindle B22
Being fixed with the driven gear wheel B27(being meshed with driver pinion B22 can also be in driver pinion B22 and driven gear wheel
Middle transition gear B 31 is engaged between B27), it is rotatably connected to circle wheel B28 on driven spindle B22, takes turns B28 circumference in circle
Side is equipped with circumferential progressive opening B24, is fixed with B23 top pillar on circle wheel B28, is rotatably connected on driven gear wheel B27
Clutch connecting lever B25, clutch connecting lever B25 is close to circle wheel B28 circumferential edge, the portion by driven gear wheel B27 under the action of torsional spring
Part installation cavity is fixed with clutch post B26 in room, and accumulation of energy connecting lever B37 is fixed on driven spindle B22, on accumulation of energy connecting lever B37
It is connected with breaker closing accumulation of energy tension spring B38；When driven gear wheel B27 rotation, clutch connecting lever B25 acts against circumferentially progressive open
Pushing circle wheel B28 to rotate up to top pillar B23 and act against the bottom breaker closing pawl B21 in mouthful B24 makes breaker closing pull
Sub- B21 is rotated and is made top be overlapped on breaker closing and turn round completion breaker closing accumulation of energy on column B20, when breaker closing is turned round
Breaker closing pawl B21 is detached from breaker closing and turns round column B20 when column B20 is rotated, and pushes third to stretch in cam rotation process
Pawl B30 rotation is out to drive breaker main shaft B34 rotation to complete breaker closing and breaker open operation accumulation of energy.
In order to which breaker closing, sub-switching operation are convenient and efficient, column B20 is turned round in breaker closing and breaker open operation turns round column
It is arranged with torsional spring on B15, is turned round in breaker closing and is fixed with breaker closing plectrum B45 on column B20, is turned round in breaker open operation
It is fixed with breaker open operation plectrum B17 on column B15, has killer switch to turn round column B18 in component installation cavity indoor location, in open circuit
Device switch is turned round and is fixed with wiper arm B16 on column B18, and when positive detorsion killer switch turns round column B18, wiper arm B16 stirs breaker
Combined floodgate plectrum B45 or breaker open operation plectrum B17 rotation, in order to which integrally-built layout can also be in wiper arm B16 and open circuit
Transition plectrum B19 is set between device combined floodgate plectrum B45 to change the rotation side that wiper arm B16 stirs breaker closing plectrum B45
To.
In order to realize that intelligent automation control, the rotation of the active rotating shaft B33 are carried out by manual or servo motor
Power source is provided；The rotation that the killer switch turns round column B18 can also provide power source by manual or electronic buckle releaser.
In order to guarantee during breaker open operation, breaker open operation pawl B14 rotates over range, in breaker open operation
It is fixed with separating brake limit swing arm B42 on pawl B14, has in component installation cavity indoor location and is matched with separating brake limit swing arm B42
The separating brake limited post (not shown) of effect.
Wherein it is preferred to which the range that the disconnecting switch turns round the positive detorsion of column B1 is 45 °, the second isolation swing arm B6 is driven
With isolation the positive 90 ° of ranges of detorsion of main shaft B7, second isolation swing arm B6 in positive detorsion across connecting column B2 be isolated lead
The position of line between axis B7 needed middle movement to realize the locking effect to isolation main shaft B7.
When the invention works, it allows isolation main shaft B7 and isolation knife power axis connection first, allows breaker main shaft B34 and open circuit
Device power axis connection；
When on-pole switch needs to close a floodgate, isolation knife is first closed a floodgate and then breaker closes a floodgate again, and rotary isolation switch counterclockwise turns round column 1
To 45 °, isolation main shaft B7 is driven to rotate clockwise 90 ° of feed motions to complete isolation knife, accumulation of energy pressure spring is isolated in this process
B4 accumulation of energy is to be locked in "on" position for isolation knife.Then manual or Electronic control active rotating shaft B33 is rotated counterclockwise, from
And driven gear wheel B27 is driven to rotate counterclockwise, clutch connecting lever B25, which is acted against, pushes circle wheel B28 inverse in circumferential progressive opening B24
Hour hands rotate up to top pillar B23 act against the bottom breaker closing pawl B21 make breaker closing pawl B21 rotate and make
Top is overlapped on breaker closing and turns round completion breaker closing accumulation of energy on column B20；Then manual or Electronic control breaker is opened
It closes torsion column B18 and stirs transition plectrum B19, transition plectrum B19 stirs breaker closing plectrum B45, and breaker closing pawl B21 is de-
Column B20 is turned round from breaker closing, pushes third projected claw B30 rotation to drive breaker main shaft in cam rotation process
Breaker closing and breaker open operation accumulation of energy are completed in B34 rotation.At the same time, locking connecting lever B39 is revolved to the isolation direction main shaft B7
Turn, so that junction panel B40 blocks the first isolation swing arm B8 to lock to isolation knife.
When on-pole switch needs separating brake, then separating brake, manual or Electronic control are disconnected again for isolation knife for breaker elder generation separating brake
Device switch in road turns round column B18 and stirs breaker open operation plectrum B17, and the second separating brake swing arm B43 is detached from breaker open operation and turns round column B15, and three
Pawl connecting lever rotates backward to complete breaker open operation, at the same time, locking connecting lever B39 opposite direction rotation, so that junction panel B40
The first isolation swing arm B8 is detached to unlock.Then, it rotates clockwise disconnecting switch and turns round column B1 to resetting, drive isolation master
Axis B7 be rotated by 90 ° counterclockwise to complete isolation knife separating brake movement, this process be isolated accumulation of energy pressure spring B4 again accumulation of energy to will
Isolation knife is locked in gate-dividing state.
