With continued reference to Fig. 1 to Fig. 6, while the second connector 121 is connected on the end of the second shaft 12, the second connection
Part 121 is connect with the second breaker main shaft extension 31 on the second breaker 3, the second connector 121 also with second connecting rod 14
Hingedly, second connecting rod 14 and the second lever 141 are hinged.
Wherein, the second connector 121 is the shackle member being clamped with the second breaker main shaft extension 31.Again specifically,
Two connectors 121 can be block, offer the second rectangle card slot 122 thereon, and the second breaker main shaft extension 31 is and the
The rectangle fixture block of two rectangle card slots 122 clamping, block have outwardly extending second connecting plate 123, the second connecting plate 123 and the
Two connecting rods 14 are hinged.Setting with this configuration can be easy to implement quickly connecting between the second connector and the second breaker
It connects.
Referring to Fig. 3 to Fig. 6, also first connecting rod 13 and second connecting rod 14 are arranged symmetrically, the first lever 131 and the second lever
141 are arranged symmetrically, and the first lever 131 and the second lever 141 are also in X-shaped arranged crosswise, the first lever 131 and the second lever 141
Infall be connected on lever shaft 15, lever shaft 15 is installed on mounting rack 1；The setting of the structure can form
Balance when one lever and the second lever motion.
Referring to Fig. 1 to Fig. 6, the first limiting section 132, the first limit are then also connected on the free end of the first lever 131
Position portion 132 limits the rotation of the second tripping draw bar 32 on the second breaker 3, and the second tripping draw bar 32 unlocks storage after rotating
The second breaker 3 under energy state, realizes the control for breaker with this.
Specifically, the first limiting section 132 be mandril, first tripping draw bar 22 be part it is exposed and have larger stress surface
L-shaped rod body mandril can accurately push up to first tripping draw bar stress surface, force unlock first tripping draw bar be connected to it is disconnected

Dress hole is connected with pivot pin, when the connector rotation with card slot, connecting rod is driven to pull up and down；Connecting rod moves up and down, and drives
Lever is rotated around in-between circular hole.
As shown in Figures 1 to 7, before breaker is not pushed into cabinet body, the shaft of interlock two sides is acted in spring torsion
Under, shaft is reversed to most lower, and card slot reaches horizontal position in shaft, i.e., is in axle extensions on the breaker of gate-dividing state
Synchronous regime.Two open circuit push-in cabinet bodies in gate-dividing state, two breakers can carry out stored energy operation.Operation such as Fig. 7
Shown in breaker 1 close a floodgate, axle extensions on breaker 1 drive the connector that card slot is had on mechanical interlock
Rotation；As shown in figure 5, connector rotation drives connecting rod to move up again, connecting rod moves up one of the lever that promotion is attached thereto
It moves up, then other one of lever rotates about center and moves down；When one, lever of a close other breaker moves down,
The rear for being displaced downwardly to circuit breaker draw bar with other one mandril of lever is arranged in.At this point, being moved to the traction of breaker
The mandril at bar rear can prevent draw bar back rotation.And when being in the breaker closing of energy storage state, it is necessary to rely on draw bar
Rotate backward unlock, since mandril limits it movement.That is, breaker cannot close a floodgate at this time.A breaker is finally reached to exist
When combined floodgate, in addition a breaker is only capable of acting in separating brake or energy storage, cannot close a floodgate simultaneously.
Thus, provided by the present embodiment it is a kind of applied to it is middle pressure double power supply automatic switching switch mechanical interlocking device and
Dual-power device changes original electrical interlocks scheme compared to the prior art, uses by shaft, connecting rod, lever etc.
The mechanical interlocking device that component is constituted, when wherein a breaker is in "on" position, in addition a breaker is only capable of locating
In separating brake or energy storage state, without can be carried out closing operation, i.e. two breakers cannot close a floodgate simultaneously, it is ensured that the safety of route can
Lean on, thus efficiently solve electrical interlocking device in the prior art it is vulnerable caused by line security problem.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
