Background technology
The current domestic conventional HXGN-12 type that is similar to high-tension switch cabinet send power operation order as follows:
During power transmission: before closing, rear cabinet door → mechanical latching gets to earthed switch in segmentation locked position of coupler → disjunction, lower earthed switch → close up earthed switch, lower earthed switch → mechanical latching gets to service position → conjunction circuit breaker.
During power failure: a point circuit breaker → mechanical latching gets to earthed switch in segmentation locked position of coupler → disjunction, lower earthed switch → close up earthed switch, lower earthed switch → mechanical latching get to maintenance position.
Locking between existing loop-network switch cabinet isolating switch and vacuum circuit-breaker all adopts the mode that is flexible coupling substantially: namely when mechanical latching gets to segmentation locked position of coupler, by the locked vacuum circuit-breaker of steel wire pull line, vacuum circuit-breaker is made not to be in closing position, namely cannot close a floodgate or force separating brake, thus avoiding misoperation to cause on-load drawing disconnecting link; And brake division loop of circuit breaker comprises and is connected in series connected fuse, on-off switch and circuit breaker successively, wherein fuse connects positive source, and circuit breaker connects power cathode.
But, because southern climates is moist, the easy corrosion of steel wire pull line of this switch cubicle, thus it is not exclusively reliable to cause steel wire to there is expansion performance, and steel wire pull line friction is large, therefore be easy to cause spring do not reset or be failure to actuate, mechanical latching after serious corrosion, may be caused normally to work, thus cause on-load drawing disconnecting link.
Utility model content
Cause the steel cable of mechanical locking device to get rusty for southern climates humidity and very easily cause on-load drawing disconnecting link not enough, the utility model aims to provide the dual error-proof device of a kind of high-tension switch cabinet, this error-proof device is on the basis of existing machinery locking device, increase by a heavy electric security device, thus reach dual anti-error, the misoperation avoiding causing because Climatic issues cause the steel cable corrosion of mechanical locking device malfunctioning, safe and reliable.
To achieve these goals, the technical scheme that the utility model adopts is:
The dual error-proof device of a kind of high-tension switch cabinet, comprises the mechanical locking device be located between high-voltage switch cabinet isolation switch and circuit breaker, and brake division loop of circuit breaker; Described mechanical locking device is connected with operating grip; Its design feature is, described brake division loop of circuit breaker to be connected one stroke switch, described operating grip drives the normally opened contact NO of described travel switch closed and segmentation locking when going to segmentation locked position of coupler, when this operating grip goes to service position B, the normally-closed contact NC of described travel switch is closed and be communicated with.
Thus, in brake division loop of circuit breaker, increase travel switch, by the action of operating grip, control the break-make of travel switch simultaneously, ensure the machinery of high-tension switch cabinet and electric dual anti-error.
Be below the technical scheme of further improvement of the utility model:
Preferably, described brake division loop of circuit breaker comprises and is connected in series connected fuse, travel switch, on-off switch and circuit breaker successively; Described fuse connects positive source, and circuit breaker connects power cathode; The normally opened contact NO of described travel switch is connected with on-off switch respectively with normally-closed contact NC, and the common port COM of the contact of the trip switch is connected with fuse.
As the structure that a kind of control travel switch specifically cut-offs, described operating grip is connected with an ejector pin, and the side of this ejector pin is provided with switch pin, and described ejector pin driving switch pin moves and makes normally opened contact NO and the normally-closed contact NC switched conductive of described travel switch.
Further, described brake division loop of circuit breaker is parallel with the normally opened contact NO of described travel switch and the common port COM of contact; Described brake division loop of circuit breaker is in series with and states the normally-closed contact NC of travel switch and the common port COM of contact.
Compared with prior art, the beneficial effects of the utility model are: the utility model adopts electrically, machinery is dual anti-error, avoid the malfunctioning and misoperation caused of steel cable corrosion because of Climatic issues mechanical locking device, therefore, than existing error-proof device safety and reliability.
Below in conjunction with drawings and Examples, the utility model is further elaborated.
