Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1, Fig. 2, Fig. 3 and Figure 4 shows that circuit breaker interlocking device of the present invention, comprise and being made up of making electromagnet 1, combined floodgate axle 2, sensitive switch 3 and 8, latching electromagnet 4, combined floodgate bent plate 5, combined floodgate connecting lever 6, combined floodgate block 7, sensitive switch 8, iron core 9, energy storage motor M etc.Front and back on combined floodgate axle 2 are connected to combined floodgate block 7 and combined floodgate connecting lever 6; Combined floodgate connecting lever 6 is connected by twisted axis with combined floodgate bent plate 5; Combined floodgate bent plate 5 is provided with long guiding hole and baffle plate, is provided with Limit screw 10 in long guiding hole, dividing plate is provided with the switch knob 14 promoting combined floodgate bent plate 5 and move, along the side of the movement locus of long guiding hole, latching electromagnet 4 is housed at the baffle plate of combined floodgate bent plate 5; Latching electromagnet 4 is when no power, and iron core 9 lower end is positioned on the movement locus of baffle plate; In the be energized end of movement locus of action of iron core 9, sensitive switch 3 is installed; In the end of the movement locus of the baffle plate of combined floodgate bent plate 5, another sensitive switch 8 is installed.At the energy storage control loop that the normally-closed contact S1 controlling positive source+KM and control to have between power cathode-KM a breaker closing control loop be in series by the normally opened contact S2 of sensitive switch 3 and the coil J of making electromagnet 1 and to carry protection switch by the normally-closed contact S of another sensitive switch 8 and energy storage motor M and energy storage motor is in series.It specifically works like this:
Dividing plate 12 in breaker mechanism is provided with making electromagnet 1, combined floodgate axle 2 is provided with combined floodgate block 7 and combined floodgate connecting lever 6, when making electromagnet 1 is energized action, its iron core clashes into combined floodgate block 7, combined floodgate axle 2 can be driven to rotate, realize closing operation.Dividing plate 13 in breaker mechanism has been installed combined floodgate bent plate 5 and latching electromagnet 4, latching electromagnet 4 is fixed installations, and the bent plate 5 that closes a floodgate is led by Limit screw 10, can horizontal slip.Latching electromagnet 4 is fixedly mounted on dividing plate 13 by mounting panel 11, its installation site is when latching electromagnet 4 no power, iron core corrects for 9 times on the track of the motion of the baffle plate of gear in combined floodgate bent plate 5 one end, therefore cannot press switch knob 14 and carry out closing by hand.On mounting panel 11, there is also mounted sensitive switch 3 and sensitive switch 8 simultaneously.Now, the sensitive switch 3 being arranged on latching electromagnet 4 top is not operating, and the normally opened contact S2 be connected in breaker closing control loop is not closed, and combined floodgate branch road is obstructed, forbids electric switch-on.When latching electromagnet 4 is in energising released state, the mechanical latching to combined floodgate bent plate 5 is removed in its lower end that iron core 9 moves upward, and now presses switch knob 14 and combined floodgate bent plate 5 can be made to move inwards, promotes combined floodgate connecting lever 6, combined floodgate axle 2 is rotated, realizes closing by hand; And the upper end of iron core 9 makes sensitive switch 3 action, be connected on normally opened contact S2 in shutting-brake control loop and close, now making electromagnet 1 is energized action, promotes combined floodgate block 7, combined floodgate axle 2 is rotated, realizes electric switch-on.When latching electromagnet 4 is in energising released state, no matter electric switch-on or closing by hand, all can make combined floodgate bent plate 5 move inwards, push down sensitive switch 8, the normally-closed contact S be connected in energy storage control loop is disconnected, cuts off the power supply of energy storage motor M, forbid automatic energy storage.If reclosing command is not removed or cause combined floodgate axle 2 to fail to reset due to various failure cause, combined floodgate bent plate 5 just press against sensitive switch 8 all the time, and normally-closed contact S disconnects all the time, and make energy storage control loop keep open circuit, energy storage motor M can not automatic energy storage always.
This device can mechanically and electrically on circuit breaker operation mechanism is interlocked simultaneously, prevent falsely close circuit breaker reliably.In addition, a whole set of interlock can be used as annex and is arranged on circuit breaker operation mechanism body, without the need to changing the structure of circuit breaker, using and installing all very convenient.
