Right plate 16 inwall is positioned at below little moveable door 3 and is also provided with travel switch.
In the utility model, 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 and the connecting lever of interlock is rotated, then the bearing pin of interlock connecting lever can rotate with connecting lever and stretch out at guide rail, now circuit breaker cannot carry out shaking into; And in the state that little moveable door is depressed, the cut-off electric operating that cannot carry out in the electrically operated loop of earthed switch ensures manual priority;
Earthed switch is at gate-dividing state, and circuit breaker shakes from test position and enters service position, and now the bearing pin of interlock connecting lever is in guide rail and very little with the gap of circuit breaker cart; Need little moveable door to depress when operational grounding switch, and depress little moveable door the connecting lever of interlock can be driven move, but because pin cannot stretch out, little moveable door cannot be depressed, now cannot carry out the operation of earthed switch, satisfied five anti-requirements.
In the utility model, the dynamic plate formation that hanging locking device comprises rectangle frame, is fixedly mounted on the fixed head in portion in face of rectangle circle, is rotatably installed in rear portion, rectangle circle face, hanging locking device is arranged on right plate outer wall operation lockhole place, time closed, little moveable door tongue is pinned, now little moveable door cannot be depressed, the operation of earthed switch cannot be carried out, meet padlock requirement.Want manual operation earthed switch and first must remove hanging locking device.
The tongue of little moveable door stretches out outside cabinet from operation lockhole, and the top spring of little moveable door tangles, and makes little moveable door be in the position on top always, only has when needing operation and just it is depressed, can automatically recover after loosing one's grip.
The spacing little moveable door of holder, 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, just can insert crank and carry out a deciliter earthed switch before cabinet.
Interlock installed by guide rail, and the angle of the connecting lever of interlock need stretch to the chain arm-tie of little moveable door.
Fitting operation macro-axis, operating mounting limit cover, fanning strip on macro-axis before installing, fanning strip is connected to the chain arm-tie in service position by pin cam pin, attention order and angle position, install the axis hole that rear low order end gos deep into pedestal, only limit the slip before and after it, rotate unaffected.
The chain arm-tie in service position, the chain arm-tie of little moveable door are vertically provided with oval through hole respectively, 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 for 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, time little moveable door is depressed, travel switch action can be made.
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, makes the connecting lever of interlock turn an angle 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; Operation operating handle, earthed switch is closed a floodgate, after combined floodgate, operation macro-axis turns an angle, and drive fanning strip to rotate, the chain arm-tie in the service position be 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 carrying out power transmission operation into circuit breaker cart in "on" position.
Prevent circuit breaker cart from closing earthed switch in service position: when circuit breaker cart shakes and enters 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, then little moveable door cannot be depressed, thus cannot carry out the operation of earthed switch by update handle, meets the five anti-requirements preventing charged conjunction earthed switch.
Because little moveable door is blocked by operation lockhole always, only have when manual operation and be just depressed, when electric operating, little moveable door is failure to actuate, only has inner interlocking gear action, thus do not affect padlock mechanism, also electric operating is not affected, if earthed switch is when electric operating, press electronic will the stopping of little moveable door and transfer manual operation to, 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.
