Wherein, described first gripper shoe 7112 includes the first lock part 7112a and the second lock part 7112b, connect between described first lock part 7112a and the second lock part 7112b and have the first spring, this first gripper shoe 7112 coordinates with cabinet door, when cabinet door closes, described first lock part 7112 coordinates realization fixed with cabinet door lock with the blade type head of cabinet door, and the most described first gripper shoe 7112 horizontal direction on dividing plate 2 moves so that described second lock part 7112b no longer blocks the first activity bar 71112；When cabinet door is opened, utilize spring Rapid reset so that the first lock part 7112b blocks the first activity bar 71112.It addition, described limit assembly may also include the 3rd rotatable parts 715.Described 3rd rotatable parts 715 include fixed component, it is fixedly installed on described disconnecting switch main shaft 211 and rotates together with described disconnecting switch main shaft 211, a big spring 7151 is had in described frame 4, described big spring 7151 is connected by the first linkage board with described fixed component, when the 3rd rotatable parts 715 rotate, stretched by the first linkage board or compression big spring 7151, big spring 7151 saves as the energy of next operation, when compounding practice bar manual operation, can the more rapid Guan Bi efficiently accomplished between disconnecting link or disconnection.Wherein, described fixed component is to have the endless member of opening, the circumferencial direction of described endless member is provided with the first extension block and the second extension block, described first extension block is described operational motion component actuation distance with the distance of described second extension block circumferencial direction, namely disconnecting switch main shaft 211 rotates between described first extension block and described second extension block, and two-end-point is respectively disconnecting switch Guan Bi or the state point of disconnecting switch disconnection.
First rotatable parts 713 described in such scheme are all one with described disconnecting switch main shaft 211 with the parts rotated, and its one end is bolted on described disconnecting switch main shaft 211, rotates with described disconnecting switch main shaft 211；The other end is flexibly connected with described first limiting plate 712 by connecting rod or band hook part.Described first limiting plate 712 can include coupling part 7121 and buckle 7122, described first limiting plate 712 chute as between described dividing plate 5 coordinates, buckle 7122 extreme lower position making described first limiting plate 712 is the most concordant with guidance panel 8 peak, this guidance panel 8 is the metal decking being arranged on dividing plate, which is provided with the first gripper shoe the 7112, second gripper shoe 7113 and round bar 7111.The coupling part 7121 of described first limiting plate 712 is flexibly connected with described first rotatable parts 713 by the second spring, namely rotate when described disconnecting switch main shaft 211, described first rotatable parts 713 rotate, the connecting rod of described first rotatable parts 713 or band hook part affect described second spring to deform upon, so that described first limiting plate 712 moves along its chute.
In order to improve processing safety, needing, many places cabinet door lock is set fixed.When needing to be serviced, service work time, first operator operate the on-off switch of vacuum switch and disconnect vacuum switch, and next utilizes action bars to run operational motion parts.When the original state that disconnecting switch Guan Bi and earthed switch disconnect, door of switch cabinet closes, first gripper shoe 7112 and the second gripper shoe 7113 are divided into described round bar 7111 both sides, described first gripper shoe 7112 is in the left side of its chute, and described first gripper shoe 7112 utilizes its first lock part 7112a to live with cabinet door lock；Described second gripper shoe 7113 is in the bottom side of its chute, and described first activity bar 71112 is blocked by described second gripper shoe 7113；Described first limiting plate 712 is on the top of its chute, i.e. buckle 7122 exceeds described dividing plate 5, and buckle coordinates realization locking further with the parts on cabinet door.After opening separating brake handle 74, second rotatable parts 714 drive the second gripper shoe 7113 to rotate counterclockwise the top side causing it to move to its chute, the second gripper shoe 7113 is made no longer to block the first activity bar 71112, when utilizing action bars to insert in round bar 7111, apply horizontal force and make it move along the loose slot of round bar 7111 to the first activity bar 71112.When action bars rotates counterclockwise, described disconnecting switch main shaft 221 is rotated counterclockwise and on the one hand disconnects disconnecting switch 213 and close the earthed switch being connected by linkage；On the one hand utilize the first rotatable parts 713 to draw described first limiting plate 712 by spring to move along its chute end direction, the buckle 7112 of described first limiting plate 712 moves to dividing plate 5 peak and stops, and can release the lock-out state of the first limiting plate 712 and cabinet door；On the one hand utilize the 3rd rotatable parts 715 by the first linkage board stretching big spring 7151, disconnect the earthed switch enough energy of storage for closing disconnecting switch 213-next time.After taking out action bars, described disconnecting switch main shaft 221 is fixed on postrotational position, cabinet door can be opened, because the cooperation of the first lock part 7112a on the blade type head on cabinet door and the first gripper shoe 7112 is to be controlled by relative deviation post, i.e. first lock part 7112 is not just to setting with blade type head, there is relative deviation post between the two, operator opens cabinet behind the door, described first gripper shoe 7112 is resetted by the first spring effect, the most described first gripper shoe 7112 blocks described first activity bar 71112, in order to avoid the maloperation when cabinet door is opened.When needs close disconnecting switch again, closing switch cabinet door, update bar turn clockwise and carry out disconnecting switch Guan Bi-earthed switch opening operation successively, the structure counteragent now linked because of rotation, it is eventually returned to original state, recycling energy accumulation handle 72 energy storage, by switch lever 73, second gripper shoe 7113 being blocked the first activity bar 71112, above-mentioned many places cabinet door lock is fixed, further increases processing safety and extends the plant maintenance cycle.Wherein energy accumulation handle 72 operation makes energy-stored spring energy storage, and to be supplied to switch lever 73 and separating brake handle 74 action, energy storage linked manner is similar or identical compared with switch cubicle operating mechanism；Switch lever 73 and separating brake handle 74 action realize the second rotatable parts 714 respectively and rotate clockwise and anticlockwise, and the second rotatable parts 714 drive the second gripper shoe 7113 downwardly and upwardly to move along its chute respectively then.
Embodiment described above is only to be described the preferred embodiment of the present invention, is not defined the spirit and scope of the present invention.On the premise of without departing from design concept of the present invention; various modification that technical scheme is made by this area ordinary person and improvement; protection scope of the present invention all should be dropped into, the technology contents that the present invention is claimed, all record in detail in the claims.
