One waist round hole is set in the middle part of interlock plate 9, the dead man 8 of a piece inclined design of setting is run through in waist round hole, 8 upper end of dead man passes through waist
Circular hole, lower end are fixedly connected on the bus contact on-off line operation mechanism main shaft 7 that one extends back in the horizontal direction；Swing arm to
It drives interlock plate 9 to move down when upper rotation is closed a floodgate, 7 rotation lock of bus contact on-off line operation mechanism main shaft is driven by dead man 8
Determine bus contact, distribution box cannot be extracted in the case where energization, avoids personal injury caused by plugging because of on-load；Swing arm is downward
The rotation unlock of bus contact on-off line operation mechanism main shaft 7 is driven by dead man 8 when rotating separating brake, distribution box can be plugged；
9 upper end of interlock plate is hingedly connected to swing arm rear end, and lower end is arranged a long lumbar hole and constitutes pilot hole, runs through bolt in pilot hole
Perhaps guide rod interlock plate lower end is by guide rod location and installation on box side or middle partition；It can also be close to connection
A caging bolt is arranged in the position on jam plate top, it is ensured that interlock plate motion stability.
Further, top plate is L shaped plate, and top plate front end is fixedly connected on chamber door medial surface by fixed plate, and intensity is high,
Reliable in action.
Further, bus contact on-off line operation mechanism main shaft one end is hingedly mounted on partition in cabinet by mounting base
On, the other end passes through bus contact connection window and extend out to outside cabinet, and limit is reliable.
Plug-in distribution box multifunctional combination latch mechanism of the invention, snap-gauge is located on vertical position when chamber door is opened, and limits
Swing arm rotates upwards, and the switch of breaker of plastic casing cannot be pushed to close a floodgate, and pushes snap-gauge to be rotated away from by top plate when chamber door is closed
The restraining position of vertical direction, the switch that upward rotation forces breaker of plastic casing is capable of in swing arm close a floodgate, while passing through interlock plate, pulling out
Bar drives the rotation of bus contact on-off line operation mechanism main shaft, locks bus plug state；Grab is upward with swing arm in making process
It is rotatably inserted into frid to cooperate and limit, chamber door cannot be opened；Once-through operation can be completed at the same time bin door switch and plastic housing is disconnected
Road device divide-shut brake interlocking, bin door switch and bus power interlock dual interlock function, it is simple and compact for structure, it is easy to operate,
It is small in size, securely and reliably.
1, equipment can only could be inserted into bus-bar system by fool proof Machine Design in the state of breaker of plastic casing separating brake,
And lock, security risk caused by electricity is picked up to avoid on-load；
2, operating shaft rotates in the forward direction, and interlocking stirs breaker of plastic casing switch and closes a floodgate；Double interlock device is during closing operation
Pass through machine driving: (1) realizing that cabinet and chamber door lock, distribution box cannot open chamber door, operator in the case where energization
Electrical body can not be touched, it is ensured that personal safety；(2) realizing takes electric equipment (distribution box) and bus device (power source body) to interlock,
Distribution box cannot be extracted in the case where energization, avoid personal injury caused by plugging because of on-load；
3, operating shaft reversely rotates, disjunction, and breaker of plastic casing switch separating brake is stirred in interlocking, while above-mentioned all interlock functions are immediately
It releases, distribution box state is that can overhaul in the case where being perfectly safe to distribution box inside without load condition, can also be with
(extraction) distribution box is safely removed at any time.
Specific technical solution:
One kind being used for bus-bar system plug type double interlock distribution box；
To ensure equipment Electrical Safety, distribution box is when bus unit takes electricity, it is necessary to assure: 1, operator cabinet door close
Closing operation is implemented to breaker (or other components) under state；2, take electric unit that cannot implement to insert under on-load state
Pull out operation.And product currently on the market is two relatively independent interlocks, needs to be operated twice, and passes through one
Fixed operation order realizes above-mentioned function.In implementation process, the operating procedure that operating personnel is completed is excessively cumbersome, and joins
Lock releases excessively mechanical (specific purpose tool is needed to complete).
Purpose:
(1) plug-in mobile power source system and bus-bar system are easy to connect, interlocking can height greatly increase safety；
(2) realization once-through operation, double interlock, operating procedure are simpler.
Interlock type distribution box main technical schemes:
1, equipment can only could be inserted into bus-bar system, and lock by fool proof Machine Design in the state of breaker open operation, with
On-load is avoided to pick up security risk caused by electricity；
2, circuit breaker operating handle is subjected to rotary closing operation, by a set of dedicated " double interlock mechanical device " by side
The circular work track that rotation process is formed is converted to the translational motion track of positive up and down direction, stirs breaker operator bar,
Breaker successfully closes a floodgate；
3, the interlock passes through machine driving during closing operation: (1) cabinet may be implemented and chamber door locks, so that matching
Electronic box cannot open chamber door in the case where energization, and operator can not touch electrical body, it is ensured that personal safety；It (2) can be real
Electric equipment (distribution box) and bus device (power source body) is now taken to interlock, so that distribution box cannot be extracted in the case where energization,
Avoid personal injury caused by due to on-load is extracted.
4, circuit breaker operating handle is subjected to reverse rotation breaking operation, stirs breaker operator bar with above-mentioned principle, broken
Road device success separating brake, while above-mentioned all interlock functions release immediately, which is that can be perfectly safe without load condition
In the case of distribution box inside is overhauled, can also safely remove (extraction) distribution box at any time.
The prior art: two interlocking structures are relatively independent, need to just be able to achieve interlocked relationship by operating step by step.
This invention: existing structure design is overturned in completion, belongs to different interlocking theories, which only needs once-through operation i.e.
Be able to achieve double interlock, Interlock Function is reliable, for operating personnel have it is easy to operate, use, maintenance, maintenance pacify very much
Congruent feature.
