Description
Technical field
The utility model relates to electric equipment, in particular a kind of vacuum circuit breaker cabinet of five anti-interlockings.
Background technology
The installation application of vacuum circuit-breaker in ring main unit is more and more general, and its structure is improved and formed on original gauge load switch cubicle basis.Oneself changes on-load switch into isolating switch most cabinets, has reduced like this cost, and dividing has no progeny also obvious visible dots, and some cabinet types also require to install JN15-12 earthed switch.Isolating switch like this, " five is anti-" interlocking more complicated between vacuum circuit-breaker, earthed switch and cabinet door.
Wherein, the specific requirement of " five is anti-" interlocking: 1, prevent from dividing and closing vacuum circuit-breaker by mistake by mistake; 2, prevent lower deciliter isolating switch of on-load state; 3, prevent in personnel's mistakenly entering into charged cabinet; 4, prevent from closing earthing under electriferous state; 5, preventing that earthing from closing in situation closes isolating switch.
In early stage breaker cabinet structure, isolating switch left-right mechanism case fitting operation axle is directly drawn from panel, circuit breaker is generally longitudinally, earthed switch lower rear plate in cabinet is installed to be installed, grounding switch main shaft is taken turns and is turned to 90 ° to draw from lower door-plate right hand edge by umbrella, and in the relevant position perforate of lower door-plate, be convenient to the lever operated ground connection of update, the main shaft other end is drawn little steel wire rope and pulley to breaker switching-on mechanism by connecting lever.Completing earthing closes and can not close the interlocking of circuit breaker, isolating switch main shaft from structure case is drawn connecting lever again by little rope traction Xiamen ground connection handle hole device in addition, after isolating switch is closed a floodgate, ground connection handle hole is by shutoff, prevent from closing earthing by mistake, this structure is commonly referred to " soft interlocking " parts disperses, Installation and Debugging complexity.
Therefore, there is defect in prior art, needs to improve.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of simple in structure, the vacuum circuit breaker cabinet of five easy to operate anti-interlockings.
The technical solution of the utility model is as follows: a kind of vacuum circuit breaker cabinet of five anti-interlockings, comprise circuit breaker, isolating switch, earthed switch, interlocked operation box and cabinet housing, described isolating switch, described earthed switch and described interlocked operation box be all arranged on described cabinet housing one on door-plate; Described isolating switch arranges isolation deciliter handle hole, described earthed switch arranges ground connection deciliter handle hole, described isolation deciliter handle hole and described ground connection deciliter handle hole are separately positioned on the dual-side of described interlocked operation box, and are directly connected with described interlocked operation box by operating axis; And described upper door-plate also arranges a moving stop.
Be applied to technique scheme, in described vacuum circuit breaker cabinet, described moving stop and described upper door-plate are respectively arranged with corresponding door lock assembly.
Adopt such scheme, the utility model arranges isolation deciliter handle hole, earthed switch by isolating switch ground connection deciliter handle hole is set, and, by on door-plate on isolating switch, isolation deciliter handle hole, earthed switch, ground connection deciliter handle hole and interlocked operation box concentrated setting one, each operation can complete at interlocked operation box, parts are concentrated, and Installation and Debugging are simple, and isolation deciliter handle hole is only directly connected with interlocked operation box by operating axis with ground connection deciliter handle hole; And, can also one moving stop be set at upper door-plate, also can realize padlock and blocking function by moving stop, use safer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The present embodiment provides a kind of vacuum circuit breaker cabinet of five anti-interlockings, and described vacuum circuit breaker cabinet can effectively be realized the requirement of five anti-interlockings, simple in structure, easy to operate.
As shown in Figure 1, vacuum circuit breaker cabinet comprises circuit breaker 106, isolating switch 107, earthed switch 104, interlocked operation box 105 and cabinet housing, wherein, circuit breaker 106, isolating switch 107, earthed switch 104 are connected with interlocked operation box 105 respectively, the disconnection and the closure that complete circuit breaker 106, isolating switch 107, earthed switch 104 by interlocked operation box, complete corresponding interlocked operation.
And, by isolating switch 107, earthed switch 104 and interlocked operation box 105 be all arranged on cabinet housing one on door-plate 103, circuit breaker 106 is arranged on the lower door-plate of cabinet shell, and, isolating switch 107 arranges isolation deciliter handle hole 101, earthed switch 104 arranges ground connection deciliter handle hole 102, isolation deciliter handle hole 101 and ground connection deciliter handle hole 102 are separately positioned on the dual-side of interlocked operation box 105, and be directly connected with interlocked operation box 105 by operating axis, isolation deciliter handle hole 101 and ground connection deciliter handle hole 102 are also separately positioned on door-plate 103, so, by the each parts of concentrated setting, can directly realize the operation of five anti-interlockings at interlocked operation box 105, easy to use, interlocked operation box 105 can only realize isolation deciliter handle hole 101 by operating axis and ground connection deciliter handle hole 102 links.
In the time of power transmission, first disconnect earthed switch 104 by the interlocked operation box 105 ground connection deciliter handle hole 102 that links, by the interlocked operation box 105 isolation deciliter handle holes 101 closed isolating switch 107 that links, observe contact and put in place again, then use manually or electric switch-on circuit breaker.
In the time of power-off, disconnect isolating switches first by interlocked operation box 105 ground connection deciliter handle hole 102 closed ground switch that link, then by 105 isolation deciliter handle holes 101 interlocks of interlocked operation box, and observe contact separating brake and put in place, can open Xiamen, guarantee load side maintainer's safety.
And upper door-plate also arranges a moving stop, so, by moving stop is set, can prevent the directly naked environment that is exposed on the external of each functional unit, make each parts easily aging, and, can also be respectively arranged with corresponding door lock assembly at moving stop and upper door-plate, for example inserting lock device, hanging locking device etc., so, can be by locking in the time not using, can prevent that layman from operating on it, guarantee personnel's fail safe.
These are only preferred embodiment of the present utility model, be not limited to the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection range of the present utility model.
