The utility model is further illustrated in conjunction with the drawings and specific embodiments.
In conjunction with shown in Fig. 1, Fig. 2 and Fig. 3, this embodiment offers a kind of integrated on-load switches to fill with cabinet door interlocking
It sets, is applied to the operation panel 1 of switchgear, and the switchgear has earthing knife-switch operating shaft 8；The integration on-load switch and switchgear
Door interlock includes latching cam 9, cabinet door deadlock lever 7, gate interlock slide plate 5 and cabinet door pressing plate 4, and all parts are set to should
On operation panel 1, specifically：
Deviate from one end of earthing knife-switch operating shaft 8 on the operation panel 1, outer is also vertically equipped with a gate interlock fixed frame 3：
On the operation panel 1, set between earthing knife-switch operating shaft 8 and gate interlock fixed frame 3 there are one horizontal locking sliding rail, which closes
Locking bar 7 can be movably arranged on the locking sliding rail, and then can be moved close to or away from the earthing knife-switch operating shaft 8；Meanwhile the couplet on the door
It locks fixed frame 3 and is equipped with horizontal-extending interlocking sliding rail, which can be movably arranged on the interlocking sliding rail, into
And can be moved perpendicular to the face where locking sliding rail, closer or far from the locking sliding rail, to realize 7 tracks of cabinet door deadlock lever
Cut-off or release.
In this embodiment, which is set in earthing knife-switch operating shaft 8, and can be rotated with the earthing knife-switch operating shaft 8, from
And there is a movement locus；The cabinet door deadlock lever 7 moves on the locking sliding rail, defines cabinet door deadlock lever 7 and is grasped close to the earthing knife-switch
One end position Chong Die with 9 movement locus of latching cam for making axis 8 is that lockset position of coupler and the end are detached from the latching cam
The position of 9 movement locus is locked position of coupler；Likewise, the gate interlock slide plate 5 moves on the interlocking sliding rail, end the cabinet
Position from lockset position of coupler to locked position of coupler that moved from of door deadlock lever 7 is initial position, far from 7 movement locus of cabinet door deadlock lever,
It is releasing position to discharge 7 free-moving position of cabinet door deadlock lever.
To realize the stable operation of mechanical interlock mechanism, it is additionally provided with interlocking elastic component 12 on the gate interlock fixed frame 3, is somebody's turn to do
Interlocking elastic component 12 is a tension spring, and one end hook acts on the gate interlock slide plate 5, makes it by release position to apply one to it
Set the active force moved towards initial position；Meanwhile further including a locking elastic component 11, which is a pressure
Spring is set on the operation panel 1, and one end contradicts and acts on the cabinet door deadlock lever 7, to apply one to the cabinet door deadlock lever 7
The active force for making it be moved towards locked position of coupler by lockset position of coupler.
The gate interlock slide plate 5 is equipped with multiple slide plate spacer pins 14 for protruding out the gate interlock fixed frame 3, cabinet door pressing plate 4
It is installed on cabinet door, during cabinet door is closed, each slide plate spacer pin 14 is corresponded on the cabinet door pressing plate 4
Position is equipped with abutting portion, which can contradict and push the slide plate spacer pin 14, to realize that couplet on the door jam plate 4 is inverse in interlocking bullet
Property part 13 active force movement, to discharge cabinet door deadlock lever 7.
The cabinet door pressing plate 4 is equipped with sealed jack, and the position of cabinet door deadlock lever 7 is corresponded on the gate interlock fixed frame 3
Equipped with a hole is kept away, passed through for the cabinet door deadlock lever 7.And then after so that the cabinet door is closed, which is supported by this
Gate interlock slide plate 5 is pushed to releasing position by contact portion by its initial position, and rear cabinet door deadlock lever 7 can be in locking elastic component 11
Elastic force effect lower edge locking sliding slot it is mobile and be inserted in the sealed jack, realize that cabinet door locks automatically.
Meanwhile further including an earthing knife-switch latch plate 10, the position that earthing knife-switch operating shaft 8 is corresponded on the operation panel 1 is equipped with operation
Hole；The earthing knife-switch latch plate 10 is to be connected on the cabinet door deadlock lever 7 to be moved with the cabinet door deadlock lever 7, and cabinet door deadlock lever 7
In lockset position of coupler, which at least partly overlaps with the handle hole, realizes the closing to the handle hole.
In conjunction with shown in Fig. 1 to Fig. 5, the embodiment operation principle is as follows：
Cabinet door is closed, the grounding switch tripping in on-load switch：Cabinet door deadlock lever 7 passes through gate interlock slide plate 5 and gate interlock
Fixed frame 3, one end are put in the oval poroid sealed jack of cabinet door pressing plate 4, and cabinet door pressing plate 4 is assemblied on cable door.Locking
Cam 9 is located within the scope of the movement locus of 7 rear end of cabinet door deadlock lever, and switch gate operating lever 6 is connect with cabinet door deadlock lever 7, mobile
Switch gate operating lever 6 drives cabinet door deadlock lever 7, the movement of cabinet door deadlock lever 7 to be blocked cam 9 and block, can not move, cabinet door is closed
Locking bar 7 can not be detached from cabinet door pressing plate 4, and cabinet door can not be opened.
Cabinet door is opened, and the earthing switch in on-load switch closes a floodgate：Earthing knife-switch operating shaft 8 is rotated clockwise, earthing switch closes a floodgate,
It drives latching cam 9 to rotate, has got out of the way cabinet door deadlock lever 7, moving switch door operation bar 6 drives earthing knife-switch latch plate 10, and earthing knife-switch is closed
Handle hole is blocked in one end of jam plate 10, while driving cabinet door deadlock lever 7, and 7 one end of cabinet door deadlock lever is detached from cabinet door pressing plate 4, simultaneously
When being also detached from gate interlock slide plate 5, gate interlock slide plate 5 blocks the hole of gate interlock fixed frame 3 under the action of interlocking elastic component 12,
For cabinet door deadlock lever 7 under the action of being latched elastic component 11, one end withstands on interlocking slide plate 5
During cable chamber door is shut, cabinet door pressing plate 4 presses slide plate spacer pin 14, takes gate interlock slide plate 5, and gate interlock is slided
Plate 5 is moved along the slot of gate interlock fixed frame 3, and gate interlock slide plate 5 gets out of the way the hole on gate interlock fixed frame 3.Cabinet door deadlock lever 7
Under the action of being latched elastic component 11, gate interlock slide plate 5 and gate interlock fixed frame 3 are passed through, is put in oval on cabinet door pressing plate 4
Hole drives switch gate operating lever 6, switch gate operating lever 6 to drive earthing knife-switch latch plate 10 simultaneously, and earthing knife-switch latch plate 10 gets out of the way handle hole
15。
Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art answers
This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details
On the utility model can be made a variety of changes, be the scope of protection of the utility model.
