Embodiment
Embodiment one:
As shown in Figure 1-2, the ring main unit circuit breaker interlocking device of the present embodiment comprises the procedure lock 1 being arranged on circuit breaker internal and the mechanical interlocks controlled by procedure lock 1, the top of procedure lock 1 is also provided with the sensitive switch 2 controlling electric close/open machine, procedure lock 1 has the bearing pin 12 that can slide up and down, procedure lock 1 carries out separating brake interlocking by bearing pin 12 driving mechanical interlock and sensitive switch 2, particularly, the top of procedure lock 1 is fixedly connected with sensitive switch 2, the upper end of bearing pin 12 is positioned at immediately below the contact of sensitive switch 2, procedure lock 1 is provided with procedure lock key 11, bearing pin 12 is driven by procedure lock key 11 and slides up and down, bearing pin 12 touches sensitive switch 2 and opens or close, it is made to play the function of electrical interlock.
Mechanical interlocks in the present embodiment comprises switch knob plate 31, opening button plate 32, pressing plate 33 and fixed head 34, opening button plate 32 is installed in rotation on the wallboard of the side of circuit breaker internal, switch knob plate 31 is installed in rotation on the wallboard of the circuit breaker internal side relative with opening button plate 32, opening button plate 32 and switch knob plate 31 are rigidly connected with two levers of circuit breaker external respectively, opening button plate 32 and lever corresponding are with it rigidly connected and are integrated, when opening button plate 32 is locked, lever corresponding with it also just cannot operate, realize the mechanical caging of sub-switching operation handle, switch knob plate 31 and lever corresponding are with it rigidly connected and are integrated, and when switch knob plate 31 is locked, lever corresponding with it also just cannot operate, and realizes the mechanical caging of closing operation handle.
In order to realize the interlocking of switch knob plate 31 and opening button plate 32, opening button plate 32 in the present embodiment is by pressing plate 33 locking, switch knob plate 31 is by fixed head 34 locking simultaneously, and pressing plate 33 and fixed head 34 are driven by bearing pin 12, the embodiment of mechanical interlocking is as follows: opening button plate 32 is installed in rotation on wallboard by installation shaft, and opening button plate 32 is also provided with limiting plate 35.Rotating shaft 36 is provided with between two relative wallboards, rotating shaft 36 arranges pressing plate 33 near one end of opening button plate 32, the middle part of pressing plate 33 is fixed in rotating shaft 36, one end of pressing plate 33 is connected with bearing pin 12, other one end of pressing plate 33 is free end, free end rotates under the driving of bearing pin 12, and the free end of pressing plate 33 coordinates locking opening button plate 32 with limiting plate 35.Rotating shaft 36 arranges fixed head 34 near one end of switch knob plate 31, and rotating shaft 36 drives fixed head 34 to turn to the below locking switch knob plate 31 of switch knob plate 31.
Such pressing plate 33 is when locking opening button plate 32, fixed head 34 also simultaneously locking switch knob plate 31, concrete mechanical interlocking process is as follows: when service routine lock 1 carries out mechanical interlocking, stir procedure lock key 11 to a point position, procedure lock 1 drives bearing pin 12 to move upward, and rotating shaft 36 is with dynamic pressure plate 33 to rotate, and the free end of pressing plate 33 is rotated down until compress the limiting plate 35 of opening button plate 32, such opening button plate 32 cannot rotate, and realizes the locking of opening button plate 32.Meanwhile, rotating shaft 36 drives fixed head 34 to rotate, fixed head 34 rotates and leans in the below of switch knob plate 31, such switch knob plate 31 cannot rotate, simultaneously because the effect of rotating shaft 36 compression plate 33 cannot upwards be rotated, switch knob plate 31 in such rotating shaft 36 also cannot upwards rotate, and switch knob plate 31 is in by locking state, can guarantee that circuit breaker is in gate-dividing state by mechanical interlocking.
When carrying out mechanical interlocking, bearing pin 12 moves upward and can trigger sensitive switch 2, sensitive switch 2 activating electrical close/open machine, and electric close/open machine controls breaker open operation, thus realizes electrical interlock.
Circuit-breaker switching on-off is controlled by mechanical interlocking and electrical interlock, realizing can also preventing on-load drawing isolation switch, mistakenly entering charged chamber, live ground wiring and switching on earth wire while existing interlocking device prevents missing drawing switch, improve the fail safe of circuit breaker.
If need the free on/off switch of circuit breaker, then can stir procedure lock key 11 to co-bit, make bearing pin 12 slide downward, now the free end of pressing plate 33 moves upward, and opening button plate 32 unlocks, fixed head 34 rotates up simultaneously, fixed head 34 departs from switch knob plate 31, and switch knob plate 31 unlocks, and the upper end of bearing pin 12 is away from the contact of sensitive switch 2, sensitive switch 2 controls electric close/open machine and unlocks, and now circuit breaker can free divide-shut brake.
As shown in Figure 2, can freely rotate to make pressing plate 33, the lower end of bearing pin 12 is provided with slide-bar 13, pressing plate 33 is provided with the axis hole be socketed on slide-bar 13 near one end of bearing pin 12, pressing plate 33 slides up and down along slide-bar 13 near one end of bearing pin 12, the bottom of slide-bar 13 is provided with locking nut, and locking nut prevents axis hole and slide-bar 13 from departing from.
