Background technology
At present, according to related distribution design specification, when there is important load in load, dual power supply scheme of electric power need to be configured,
This is accomplished by configuring primary breaker and back-up breaker in electrical control cubicles, and primary breaker can only be with back-up breaker simultaneously
There is one to be in operating position, existing breaker control mechanism is usually the turnover using manual lead screw mechanism controls breaker,
The controlling organization is higher to requirement on machining accuracy, and using dumb, easily occurs screens, is difficult to reset, meanwhile, breaker with
Back-up breaker is to be respectively controlled, once maloperation, easily occurs primary breaker with back-up breaker while in work
The situation of state, is also easy to produce maloperation and causes equipment fault, personal safety is endangered when serious.
The content of the invention
It is an object of the invention to：A kind of breaker control mechanism in switch cubicle is provided, to solve existing open circuit
Device controlling organization is high to requirement on machining accuracy, using dumb, easily occurs screens, is difficult to reset, meanwhile, once maloperation, easily
The problem of occurring breaker and back-up breaker simultaneously in running order situation.
To solve the above problems, intend using such a breaker control mechanism in switch cubicle, the switch cubicle
Inside include two to be arranged side by side in the breaker on laminate, the rear side of each breaker is correspondingly arranged on a breaker and connect
It is additionally provided with head, each breaker for driving the movable screw mandrel of breaker, the section of screw mandrel is non-circular structure, institute
Non-circular structure is stated for ellipse, triangle, rule or irregular polygon, the rear side and circuit breaker connector of one of breaker
Between be additionally provided with lift driving sliding block, lift drive sliding block towards the side of the breaker be Falling Wedge structure, separately
It is correspondingly arranged on lift screw mandrel limited block, laminate to be correspondingly arranged on immediately below screw mandrel in one breaker and is driven for lift
The through hole that movable slider and lift screw mandrel limited block pass through, the lower end of the lift driving sliding block and lift screw mandrel limited block
The two ends of lever are fixed on by the connecting rod correspondence being through in through hole, the lower end of the lift screw mandrel limited block, which is also corresponded to, to be set
It is equipped with back-moving spring.
As preferred structure, a lift driving is provided between the rear side and circuit breaker connector of two breakers and is slided
The underface of screw mandrel is also correspondingly arranged on a lift screw mandrel limited block in block, two breakers, and the lever has two
Individual, the lift driving sliding block corresponding to each breaker leads to the lift screw mandrel limited block corresponding to another breaker
Cross the two ends that connecting rod is correspondingly arranged in a lever.
More effectively to ensure the limit effect to breaker, lift screw mandrel limited block may be contained within corresponding open circuit
Between device and circuit breaker connector.
The lift drives sliding block with the breaker corresponding to it under contactless state, under lift is driven in sliding block
The upper end position for dropping wedge structure is higher than Falling Wedge structure in breaker lower end position, and lift driving sliding block
Lower end position be less than breaker lower end position.
As preferred position limiting structure, the length direction of the upper end edge screw mandrel of lift screw mandrel limited block offers screw mandrel limit
Position groove, the width of screw mandrel stopper slot is more than the section minimum widith of screw mandrel, less than the Breadth Maximum in screw mandrel section.
Compared with prior art, major advantage is that the breaker control mechanism ensure that one of breaker to the present invention
When being connected with end line thereafter, breaker promotion lift driving sliding block declines the sliding block, and according to lever principle, lever is another
The lift screw mandrel limited block of one end rises to block the drive screw of another breaker, so as to ensure another breaker
It is not turned on, so as to veritably avoid occurring the breaker situation simultaneously in running order with back-up breaker, strengthens equipment
Protecting effect, it is to avoid cause equipment fault, meanwhile, the controlling organization is relatively low to requirement on machining accuracy, using more flexible, is difficult
It is the problems such as generation screens, more practical, through actual test popularization and application preferably.
