Abstract
Interlocking function between position of handcart and on/off states of breaker as well as between position of handcart and on/off states of earthing switch are realized in active locking mode. Usinga locking bar and ganged regulating lever driven by baffle, which can restrict insertion of the advance operation handlebar of breaker handcart, implements mechanical linkage. The baffle can be movedat off, working and test positions of breaker. The baffle cannot be moved when advance process from test position to working position is carried on, and in 'on' position of the breaker. In test and working positions, the baffle is moved to the position so as to block off receptacle of the advance operation. Thus, switching in mechanism of the breaker is unlocked, and switching in operation allowsto be operated, meanwhile switching in operation for earthing switch is restricted. If earthing switch is in 'on' position, then the advance operation handlebar of breaker handcart is restricted.
Description
Technical field
The present invention relates to a kind of 12KV handcart-type switch board breaker handcart interlocking gear, realize handcart switch cabinet five anti-chain functions by install this interlocking gear additional at circuit breaker cart.
Background technology
The handcart type high-voltage switch cabinet must be provided with a cover interlocking gear in order to guarantee safety of operators, this mechanism should realize following function: 1. the breaking-closing operating that can carry out circuit breaker when handcart is positioned at test and service position, by test position to the progradation of service position then can not, handcart can not carry out the forward operation of handcart when closing a floodgate; 2. when circuit breaker cart was in progradation or service position, earthed switch can not close a floodgate, and when earthed switch was in "on" position, earthed switch can not be advanced into the service position by test position, and this has made clear and definite regulation in the GB3906 the inside.Most of products have in the market been taked the mode of passive locking when realizing this chain function, can insert the propulsive mechanism operating grip as circuit breaker when closing a floodgate and carry out the handcart forward operation, but operate motionless.The problem of passive chain existence has been to increase the possibility of misoperation.
Summary of the invention
The present invention aims to provide a kind of new mechanical interlocking gear, adopts the Active Locking mode when realizing chain function, can not insert the propulsive mechanism operating grip as circuit breaker when closing a floodgate and carry out the handcart forward operation.
The present invention adopts following technical scheme:
A kind of handcart high-voltage switch cabinet mechanical interlock mechanism, mainly by baffle plate, first jam plate, second jam plate, first connecting lever, second connecting lever, the 3rd connecting lever, latch lever, location-plate is formed, described baffle plate can horizontally slip in opening and close the propulsive mechanism operator two positions of jack, by blocking or exposing the forward operation that the propulsive mechanism operator comes jack the limiting circuit breaker handcart, first connecting lever that slides through of baffle plate drives the latch lever rotation, be socketed with second connecting lever that rotates synchronously with this latch lever on the latch lever, the rotation of latch lever drives first jam plate by second connecting lever and rotates, when baffle plate is allocated to open position, first jam plate pins the switching-on mechanism of circuit breaker, circuit breaker can not close a floodgate, when baffle plate is allocated to off-position, first jam plate is with the breaker switching-on mechanism release, circuit breaker can close a floodgate, if circuit breaker closes a floodgate simultaneously, the combined floodgate connecting lever of circuit breaker blocks first jam plate, baffle plate is limited at off-position, can not carry out the forward operation of handcart, behind the breaker open operation, the combined floodgate connecting lever of circuit breaker discharges first jam plate, can carry out the handcart forward operation, be socketed with on the latch lever and its 3rd connecting lever that rotates synchronously, the rotation of latch lever drives second jam plate by the 3rd connecting lever and horizontally slips, when baffle plate is allocated to open position, second jam plate slides to the right the earthed switch closing device is pinned, earthed switch can not close a floodgate, the motion of second jam plate is lived the switch cubicle door lock simultaneously, when if earthed switch is in closing position, closing device blocks second jam plate, baffle plate can not be allocated to open position, can not carry out the forward operation of handcart, the latch lever cross section is the four directions, be provided with two place's circular recesss thereon, one place is a test position, one place is the service position, the location-plate of a band square hole is set on the travelling frame of handcart, the travelling frame of it and handcart slides along latch lever together, the rotation of latch lever can only be carried out when circuit breaker is positioned at test and service position by the constraint of location-plate, when moving to two circular recess places, can stir baffle plate and drive the latch lever rotation, and the rotation of latch lever is limited when mediating.
This interlocking gear is realized the chain function of the opening and closing state of handcart position and circuit-breaker switching on-off state and earthed switch in the Active Locking mode, drive latch lever and realize mechanical chain between handcart position and the circuit breaker by a baffle plate that can limiting circuit breaker handcart forward operation handgrip inserts with the connecting lever that latch lever links, baffle plate when breaker open operation and work and test position can about stir, when reaching breaker closing by test position to the progradation of service position, can not stir handcart, when test and service position, baffle plate is allocated to the position that circuit breaker cart forward operation handgrip jack is blocked, the switching-on mechanism of circuit breaker is unlocked, can carry out closing operation, the rotation of latch lever drives a jam plate and horizontally slips, the restriction of ground switch closing operation achieves a butt joint, if earthed switch is in closing position simultaneously, the motion of jam plate is limited, and can't stir the forward operation that baffle plate carries out circuit breaker cart.
