Right plate 16 inwalls are positioned at little moveable door 3 belows and are also provided with travel switch.
In the present invention, circuit breaker cart is in test position, open hanging locking device, press little moveable door, now can insert crank, carry out point closing operation of earthed switch, after earthed switch closes a floodgate, operation macro-axis drives fanning strip to rotate, and the chain arm-tie in service position can move downward the connecting lever of interlock is rotated, then the bearing pin of interlock connecting lever can with connecting lever rotate stretch out at guide rail, now circuit breaker cannot shake into; And the state of depressing at little moveable door, the electrically operated loop of earthed switch is cut off cannot carry out electric operating guarantee manual priority;
Earthed switch is at gate-dividing state, and circuit breaker shakes and enters service position from test position, and now the bearing pin of interlock connecting lever is in guide rail and very little with the gap of circuit breaker cart; When operational grounding switch, little moveable door need to be depressed, can drive the connecting lever motion of interlock and depress little moveable door, but because pin cannot stretch out and cannot depress little moveable door, now cannot carry out the operation of earthed switch, meet five anti-requirements.
In the present invention, hanging locking device comprises rectangle frame, be fixedly mounted on the fixed head of portion in face of rectangle circle, the moving plate that is rotatably installed in rectangle circle face rear portion forms, hanging locking device is arranged on right plate outer wall operation lockhole place, when closed, little moveable door tongue is pinned, now little moveable door cannot be depressed, cannot carry out the operation of earthed switch, meet padlock requirement.Want manual operation earthed switch and must first remove hanging locking device.
The tongue of little moveable door stretches out outside cabinet from operation lockhole, and the top of little moveable door tangles with spring, makes the little moveable door position in top always, only has when need to operating and just it is depressed, and after loosing one's grip, can automatically recover.
Holder, the spacing little moveable door of locating piece only can slide up and down, and pedestal, locating piece are fixed on the right plate of cabinet, the motion before and after restriction little moveable door.Operation macro-axis is rotatably installed in the axis hole of pedestal, depresses little moveable door from cabinet, just can insert crank and carry out a deciliter earthed switch.
Interlock is installed on guide rail, and the angle of the connecting lever of interlock need be stretched to the chain arm-tie of little moveable door.
Fitting operation macro-axis, operating mounting limit cover, fanning strip on macro-axis, is connected to the chain arm-tie in service position by pin cam pin on fanning strip before installing, attention order and angle position, install the axis hole that rear low order end gos deep into pedestal, only limit the slip of its front and back, rotate unaffected.
On the chain arm-tie in service position, the chain arm-tie of little moveable door, be vertically provided with respectively oval through hole, bearing pin on interlock connecting lever is through oval through hole on the chain arm-tie in service position, the chain arm-tie of little moveable door, by chain service position arm-tie, the chain arm-tie pin joint of little moveable door, bearing pin can slide up and down in the oval through hole on the chain arm-tie in service position, the chain arm-tie of little moveable door.
Below right plate operation lockhole, travel switch is installed, when little moveable door is depressed, can be made travel switch action.
The closing by hand operation of earthed switch: first remove hanging locking device, press little moveable door update handle, now little moveable door is depressed state, turns an angle the connecting lever of interlock by the chain arm-tie interlock of little moveable door.Guide rail place, the bearing pin of interlock connecting lever rotates and stretches out, now circuit breaker cart cannot shake into; Operating operation handle, earthed switch is closed a floodgate, after combined floodgate, operation macro-axis turns an angle, and drives fanning strip to rotate, and the chain arm-tie in service position being connected with fanning strip is also pulled, the connecting lever of interlock is turned an angle, guide rail place, the bearing pin of interlock 7 stretches out, now circuit breaker cart cannot shake into; Meet earthed switch and cannot shake the five anti-requirements of carrying out power transmission operation into circuit breaker cart in "on" position.
Prevent that circuit breaker cart from closing earthed switch in service position: circuit breaker cart shakes while entering service position, the chassis vehicle of circuit breaker cart is just on guide rail, now need to press little moveable door and could carry out operational grounding switch by update handle, because circuit breaker chassis is on left and right sides guide rail, the bearing pin of interlock now cannot stretch out, little moveable door cannot be depressed, thereby cannot carry out the operation of earthed switch by update handle, meets and prevents charged five anti-requirements of closing earthed switch.
Because little moveable door is that operation lockhole is blocked always, when only having manual operation, be just depressed, when electric operating, little moveable door is failure to actuate, only has inner interlocking gear action, thereby do not affect padlock mechanism, do not affect electric operating yet, if earthed switch is in the time of electric operating, press that little moveable door is electronic will stop transferring to manual operation, meet manual priority, this chain scheme, solve electric operating, the incompatibility problem of manual operation and padlock, and meet the requirement of manual priority, it is a kind of interlocking gear of novel form, for intelligent middle cabinet provides perfect solution.
