This equipment is mainly used in transformer station and stops power transmission control, equipment upper static contact 14 connects transformer station's power supply buses, lower fixed contact 15 connects client's outlet, and circuit breaker 12 Main Function realizes bus and outlet conducting power transmission or disconnect to have a power failure with disconnecting by the connection of upper moving contact 23, lower moving contact 24 and upper static contact 14, lower fixed contact 15.
Circuit breaker 12 is slided on rails 19 by roller 22 and realizes pushing or pulling out of circuit breaker 12, when equipment needs power transmission, circuit breaker 12 pushes in casing along guide rail 19, after circuit breaker 12 pushes certain position, push pedal 21 promotes push shaft 4, then cause upper rotating plate 2 rotates along fixed axis 5 with lower flap 3, upper rotating plate 2 is moved downward with axle, and lower flap 3 moves upward.By the rotation of upper rotating plate 2 and lower flap 3, then upper rotating plate 2 is made to drive short rod 18 to pull downwards, lower flap 3 drives long draw 17 upwards to rotate, drop-down by short rod 18, then lower baffle plate 16 is driven to move downward, by above pushing away of long draw 17, then moving upward of overhead gage 13 is driven, thus expose lower fixed contact 15, upper static contact 14, when upper lower baffle plate is opened completely, circuit breaker 12 enters the inside, and upper moving contact 23 is connected with upper static contact 14, lower moving contact 24 and lower fixed contact connect 15, and equipment completes power transmission.
Whole system comprises: controller, actuator and position detecting system; Controller is used for receiving position signal, Logic judgment, output signal, and control actuator, controller is made up of the electronic circuit such as housing, single-chip microcomputer; Actuator, be used for realizing directly controlling the motion of upper rotating plate 2 and lower flap 3, actuator is made up of motor mounting plate 25, stepping motor 26, travel switch 27, rotating shaft 28, rotating shaft 29 support; Position probing, detect circuit breaker position and direction of operating, position detection part is by magnet 20, Hall element A7, and Hall element B8 forms.
When magnet 20 aligns with Hall element A7, Hall element A7 can by cable transmission signal to controller 6, now system can judge that now circuit breaker will enter box house power transmission, then controller 6 is made to output signal to actuator, thus make stepping motor 26 drive actuator to reset, both the horizontal lever of rotating shaft 28 was parallel with casing 9 left plate, and upper rotating plate 2 and lower flap 3 can freely rotate, and circuit breaker 12 can push power transmission.Hall element B8 aligns with magnet 20, system can judge that now dolly shifts out state, detection signal can be sent into controller 6 by Hall element, then controller 6 can output signal, Driving Stepping Motor 26 rotates 90 °, make the horizontal lever of rotating shaft 28 vertical with casing 9 left plate, the horizontal lever of rotating shaft 28 blocks upper rotating plate 2 and lower flap 3 cannot rotate, thus overhead gage 13 and lower baffle plate 16 cannot be opened.
Preferably, the horizontal lever of rotating shaft 28 can change corrosion resistant plate into, connects more reliably light.
Preferably, stepping motor 26 can change DC speed-reducing into, forms by increasing the opening and closing that switch controls actuator.
Preferably, the replaceable one-tenth optoelectronic switch of travel switch, Position Control can be more accurate.
Preferably, actuator and controller 6 can be made of one, and are convenient to install.
Due in existing equipment use procedure, after circuit breaker 12 shifts out casing, whole box house is completely unlimited, personnel arbitrarily can enter casing, but now upper static contact 14 is likely charged, now overhead gage 13 and lower baffle plate 16 can arbitrarily be opened, if personnel are strayed into open baffle plate, will cause personnel's electric shock accidents.Prevent mistakenly entering charged chamber for solving, special development this patent middle-placed switch cabinet valve automatic control equipment, after circuit breaker shifts out casing, controls automatically to baffle valve.Fork limited position stoppage system adopts step motor control, and Hall detection position, single-chip microcomputer processing logic, possess skills advanced person, implements the features such as reliable.This system detects little truck position by Hall, and processor by the little truck position of Logic judgment, rotates to trigger stepping motor, the opening and closing push rod of locked backboard, thus realizes after middle cabinet trolley shakes out, locking backboard; Middle-placed switch cabinet is when inspection operation, and after dolly leaves cabinet, the backboard of automatic blocking middle-placed switch cabinet, system has the functions such as automatic detection, judgement, action, and realizing system controls automatically, prevents personnel's mistakenly entering charged chamber.
It may be noted that, above-mentioned execution mode is only the preferred embodiment of the invention, and for those skilled in the art, under the prerequisite meeting operation principle of the present invention, any equivalent or similar replacement all falls into protection scope of the present invention.
