Specific embodiment
The exemplary embodiment for embodying feature of present invention and advantage will describe in detail in the following description.It should be understood that
The present invention can have various variations in different embodiments, neither depart from the scope of the present invention, and theory therein
Bright and diagram inherently is illustrated as being used, rather than to limit the present invention.
Principle and structure in order to further illustrate the present invention carry out the preferred embodiment of the present invention now in conjunction with attached drawing detailed
It describes in detail bright.
Referring to Fig. 1, the embodiment of the present invention proposes that a kind of switchgear 1, the switchgear 1 have cabinet body 10, earthing switch
It 20 and closes a floodgate or the operation axis 30 of separating brake for controlling the earthing switch 20.Cabinet body 10 includes a cavity, and cabinet body 10 has
There is panel.Control button, electric meter, display board etc. are installed on the panel.Partition is also typically included in the cabinet body 10,
The cavity in cabinet body 10 is separated into multiple portions.The earthing switch 20, operation axis 30 are mounted in cabinet body 10.
Specifically, earthing switch 20 has gate-dividing state and "on" position.In one embodiment, operation axis 30 can lead to
Transmission gear is crossed to connect with earthing switch 20；Certain this programme does not limit operation axis 30 and opens in other manners with the ground connection
Close 20 connections.Manually or electrically mode controls operation axis 30 to operator, so that operation axis 30 passes through rotation, translation
Etc. modes realize control earthing switch 20 state.The operation axis 30, which has, corresponds to 20 "on" position of earthing switch
When closing position and open position when corresponding to 20 gate-dividing state of earthing switch.
Please see Fig. 2 to Fig. 4, the switchgear 1 in the present embodiment further includes interlock 40, and the interlock 40 is corresponding
It is arranged in the closing position or open position of the operation axis 30, the interlock 40 includes locking part 410, locking mechanism
420 and procedure lock 430: there is engaging position 411 on locking part 410；The locking part 410 connect with the operation axis 30 and
It is mobile with the operation axis 30, so that described be located at the closing position or the open position in the operation axis 30
When, the engaging position 411 is moved to position to be locked.Locking mechanism 420 includes sequentially connected operating parts 421, transmission component
422 and locking piece 423；The operating parts 421 can be mobile relative to the cabinet body 10, and passes through the transmission component 422
It is mobile to drive the locking piece 423, so that when the engaging position 411 is located at the position to be locked, the locking piece 423
It can be moved to and engage with the engaging position 411, to lock the position of the operation axis 30；Procedure lock 430 and the cabinet
Body 10 connects, and described program lock 430 has lock state and opening state；At the locking piece 423 with the engaging position 411
When fastening state, described program lock 430 is connect with the locking mechanism 420, to lock the position of the locking mechanism 420.
In the present embodiment, the switchgear 1 has two sets of interlocks 40, and two interlocks 40 are used respectively
In the closing position and open position that lock the operation axis 30；Claiming two interlocks 40 in the examples below is respectively to close
Lock interlock and separating brake interlock.The locking part 410 of two interlocks 40 is along the extension side of the operation axis 30
To setting gradually.
In some embodiments, transmission component 422, which can be, drives locking plate by electrical components, such as motor, cylinder
4231 are promoted, and operator promotes locking by control operating parts 421, such as button or controller, to manipulate transmission component 422
Piece, so that locking plate be made to connect with the engaging position 411 of locking part 410.In the present embodiment, the operating parts 421 is in long strip-board shape,
Have on mainboard 51 for the perforative notch of operating parts 421,51 plate face of mainboard is substantially vertical with the glide direction of operating parts 421.Institute
Stating operating parts 421 can slide relative to the cabinet body 10, and the one end of operating parts 421 far from connecting rod 4221 is operating side, the behaviour
Make end with handle, and the handle stretches out and panels outside, for operator's gripping.
In the present solution, the mobile direction of locking mechanism 420 can there are many, when operation axis 30 is to close a floodgate or open position
When, locking mechanism 420 is engaged to realize with the engaging position 411 on locking part 410 by the modes such as moving horizontally or rotating.
In the present embodiment, the operation axis 30 is by rotation to switch to the closing position or the open position；It is described
Latch fitting 410 follows the operation axis 30 to rotate；When the operation axis 30 is in "on" position or gate-dividing state, the engaging
Position 411 is located at the bottom of the locking part 410；The locking mechanism 420 include locking piece 423 and with drive the locking piece
423 lifting assemblies promoted；The lifting assembly is by promoting the locking piece 423, so that the locking piece 423 and the card
Coincidence 411 engages.
In the present embodiment, operation axis 30 is by rotation to switch to the closing position or the open position；Institute
Locking part 410 is stated to rotate with the operation axis 30；When the engaging position 411 is located at the position to be locked, the engaging
Position 411 is located at the bottom of the locking part 410；The transmission component 422 is by promoting the locking piece 423, so that the lock
Determine part 423 to engage with the engaging position 411.
Illustrate the course of work of this programme interlock by taking earthing switch 20 switches to separating brake by combined floodgate as an example herein.Work as behaviour
Make main shaft 30 by rotation, when earthing switch 20 is switched to gate-dividing state by "on" position, since locking part 410 is described
Operation axis 30 connects, therefore locking part 410 can be rotated synchronously with the rotation of operation axis 30, and then the locking part
Engaging position 411 on 410 can also rotate with the operation axis 30 and synchronize and rotate.When earthing switch 20 switches to separating brake
When state, when the correspondence of operation axis 30 turns to open position, locking mechanism 420 is moved at this time, with real with engaging position 411
Now connect, thus the position for the position 411 that is locked and fastened, and then the position of the locking piece, since locking piece is to be connected to operation master
On axis 30, therefore by locking the position of locking piece, to achieve the purpose that lock operation main shaft 30.
Further, procedure lock 430 has lock state and opening state, in the locking piece 423 and the engaging position
411 when being in fastening state, and described program lock 430 is connect with the locking mechanism 420, to lock the locking mechanism 420
Position, thus locking mechanism 420 and engaging position 411 keep connection status, so that operation axis 30 is locked in open position.
