The use principle of the vacuum distribution equipment of the present embodiment is as follows:
Enter car state, understood incorporated by reference to Fig. 3, first this door closure 1 is sticked on this bearing 18, then, is understood incorporated by reference to Fig. 1-2, be rotated counterclockwise this locking bar 2, make this locking bar 2 depart from this stopper slot 25, this door closure 1 of locking can be realized.Now this button spindle 11 departs from the constraint of this locking bar 2, this button panel 12 support compel effect under, elastic reset.Meanwhile, this yoke plate 13 elastic reset under the effect of the extension spring of this button panel 12, to remove the constraint to this scotch 17, is understood incorporated by reference to Fig. 4, makes this leading screw 16 have the degree of freedom of rotation.By shaking this handle 21 clockwise, this leading screw 16 can be driven to rotate, by driving this handcart 10 and then realizing the object that those moving contacts 23 are plugged in those fixed contacts 22.In the process entering car, understood incorporated by reference to Fig. 2, this pivot 9 drives this shift fork 3 to rotate, and this shift fork 3 this guide vane end stop 5 that links rotates, and this stopper slot 25 departs from the axis direction of this locking bar 2 gradually, and little by little trends towards the axis direction of this gangbar 7.
Combined floodgate "on" position, when those moving contacts 23 are positioned in those fixed contacts 22 completely, please continue to be understood in conjunction with Fig. 1-2, the opening of this stopper slot 25 is relative with the axis direction of this gangbar 7, this gangbar 7 (can be under gravity, also can under the effect of elastic force) insert this stopper slot 25 so that remove to this manual brake 8 constraint, now this locking bar 2 supports under the pressure of on this door closure 1 by the outer rim of this guide vane end stop 5.This circuit breaker can be connected by rotating this manual brake 8.Under combined floodgate "on" position, please continue composition graphs 4 to be understood, electric current enters this inlet wire interstar connection room 19 by inlet wire cable drum 20, electric current enters secondary chamber 29 by this inlet wire interstar connection room 19, and flow through those fixed contacts 22, those moving contacts 23, the vacuum interrupter of this circuit breaker and this connection platform interstar connection room 24 successively, so-called connection platform is connected another (or multiple stage) vacuum distribution equipment exactly, and connection platform after-current eventually passes through outlet cable drum 30 and flows out.
Go out car state, please continue to be understood in conjunction with Fig. 1-2, this circuit breaker is disconnected by rotating this manual brake 8, by shaking this handle 21 counterclockwise, this leading screw 16 can be driven to rotate, please continuing composition graphs 5 to be understood, by driving this handcart 10 to retreat, and then realizing those moving contacts 23 object of departing from mutual to those fixed contacts 22.In the process of moving back car, please continue composition graphs 2 and be understood, this pivot 9 drives this shift fork 3 to rotate, and this shift fork 3 this guide vane end stop 5 that links rotates, and this stopper slot 25 departs from the axis direction of this gangbar 7 gradually, and trends towards the axis direction of this locking bar 2.
Enabling inspecting state, please continue composition graphs 5 to be understood, when those moving contacts 23 depart from those fixed contacts 22 completely, please continue composition graphs 2 to be understood, press this button spindle 11, make spacing firmly this scotch 17 of this jam plate 14, hold onto the rotary freedom of this leading screw 16, therefore this handcart 10 translation is forbidden, the opening of this stopper slot 25 is relative with the axis direction of this locking bar 2, turn clockwise this locking bar 2, this locking bar 2 is made to insert this stopper slot 25, to remove the constraint to this door closure 1, and then realize the object opening this door closure 1, now this gangbar 7 is supported under the pressure of on this manual brake 8 by the outer rim of this guide vane end stop 5, closing by hand is forbidden with this.
Need it is noted that, the local of this door closure is only depict only in Fig. 1-2, and eliminate section connecting element to make those skilled in the art clearly can understand cooperation relation between each main parts size, in addition, also door closure is removed in Fig. 4 and Fig. 5, here the cooperation relation (or in order to explain the working mechanism knowing this device) allowing this area research staff can understand the main parts size of enclosure interior is mainly considered, actual enters car or goes out in car process, and the removal of door closure is absolute prohibition.
The interlocking device of the present embodiment and vacuum distribution equipment have following technique effect:
The first, can to interlock this door closure and this manual brake, by rotating this guide vane end stop, a rod member in this locking bar and this gangbar can be made to support under the pressure of in the outer rim of this guide vane end stop, and meanwhile another rod member is plugged in this stopper slot, and can rotation replace, achieve the interlock of two rod members with this, and then realize the object of this door closure of interlocking and this manual brake, improve security performance.
Second, can to interlock this door closure and this handcart, because the condition opening door closure this locking bar 2 is side by side inserted the locked groove of this stopper slot 25 and this button spindle 11 (lock projection inserts locked groove), but the condition that the locked groove of this button spindle 11 is aimed at this locking bar 2 is this jam plate 14 is limited in this scotch 17 (namely this button spindle 11 is in the state pressed), but this scotch 17 limited live after, this leading screw 16 cannot rotate, namely this handcart 10 cannot translation, therefore by this handcart 10 and this door closure 1 reciprocal interlocking (namely, to open this door closure 1 must in advance spacing live this handcart 10), the misoperation after opening door closure can be prevented.
Although the foregoing describe the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present invention and essence, can make various changes or modifications to these execution modes, but these change and amendment all falls into protection scope of the present invention.
