Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is further described.
The embodiment of the utility model is referring to figs. 1 to shown in 3; The breaker mechanism of a kind of 126KV closes the branch interlock; Comprise separating brake semiaxis 4, separating brake dropout plate 5, switching winding 6, combined floodgate semiaxis 11, combined floodgate dropout plate 12 and closing coil 13, also comprise connecting lever 1, screw pin 2, interlock plate 3, interlocking connecting lever 7, torsion spring 8, interlocking latch 9 and spring pivot 10, the bent angle top of connecting lever 1 is provided with a screw pin 2; Interlock plate 3 one ends are connected with connecting lever 1 through screw pin 2; And interlock plate 2 can be relatively and connecting lever 1 be rotated, the other end of interlock plate 3 is connected with interlocking connecting lever 7 through interlocking latch 9, the connecting lever 7 of interlocking is provided with torsion spring 8; And an end of said torsion spring 8 is connected with interlocking latch 9; Side-lower at interlocking connecting lever 7 is arranged at spring pivot 10, and spring pivot 10 is fixedly connected with combined floodgate semiaxis 11, and combined floodgate dropout plate 12 is connected with combined floodgate semiaxis 11 and is arranged on combined floodgate dropout plate 12 sides.
Connecting lever 1 corner is provided with a regular hexagon through hole, and connecting lever 1 is that orthohexagonal rotating shaft one end is connected through this a regular hexagon through hole and a cross section, and the other end of rotating shaft is connected with the on/off switch elevating lever; When separating brake, the on/off switch elevating lever drives rotating shaft and turns clockwise; Connecting lever 1 turns clockwise under rotating shaft drives, when closing a floodgate, and the on/off switch elevating lever; The drive rotating shaft is counterclockwise, and connecting lever 1 is rotated counterclockwise under rotating shaft drives, and the position that interlock plate 3 is connected with interlocking latch 9 is provided with a long slot bore; Slotted eye is waist shape, and interlocking latch 9 can move in the long slot bore of interlock plate 3, and long slot bore is the unique design of waist shape on the interlock plate 3; When making mechanism's output angle big, interlocking connecting lever 7 anglecs of rotation are less; The corner of interlocking connecting lever 7 is provided with rotating shaft, and said torsion spring is coaxial with interlocking connecting lever 7.
Combined floodgate spring and sluice separating spring release energy and are being with connecting lever to do to move counterclockwise with clockwise respectively; The motion of connecting lever drives interlock plate and moves, and the motion of interlock plate drives the interlocking connecting lever and rotates, and the rotation of interlocking connecting lever is the constraint of closing the branch interlocking; The interlocking connecting lever moved clockwise and withstands the spring pivot in the combined floodgate semiaxis after mechanism closed a floodgate; The combined floodgate semiaxis can not turn clockwise again, and the interlocking connecting lever moves counterclockwise and gets out of the way certain angle behind mechanism's separating brake, and the combined floodgate semiaxis can turn clockwise.
Its operating principle is:
Interlock Status during separating brake: during separating brake, connecting lever 1 is done motion clockwise and is being with interlock plate 3 promotion interlocking connecting levers 7 to do motion counterclockwise, and while torsion spring 8 is twisted.Separating brake is accomplished, and connecting lever 1 puts in place, and interlocking connecting lever 7 gets out of the way angle, and interlocking connecting lever 7 has very big free gap with spring pivot 10.When mechanism need close a floodgate, closing coil 13 was received switching signal, and the moving iron core of closing coil 13 moves forward and promotes combined floodgate dropout plate 12, and combined floodgate dropout plate 12 is being with combined floodgate semiaxis 11 to move clockwise, is being with spring pivot 10 to move clockwise simultaneously.At this moment mechanism does not also close a floodgate and is in gate-dividing state, and the angle that interlocking connecting lever 7 gets out of the way makes the clockwise rotation of spring pivot 10 unfettered, after the moving iron core of closing coil 13 is shifted the position onto, closes a floodgate and accomplishes.Therefore, when mechanism was in gate-dividing state, mechanism can close a floodgate.
Interlock Status during combined floodgate: during combined floodgate, connecting lever 1 is done motion counterclockwise and is being with interlock plate 3 to move upward, and interlocking latch 9 loses constraint, interlocking connecting lever 7 clockwise rotation under the twisting force of torsion spring 8.After combined floodgate put in place, interlocking connecting lever 7 heads were by frame upper arresting pin constraint fixed position, and the arc surface of interlocking connecting lever 7 withstands spring pivot 10.The moving iron core of closing coil 13 moves forward; The lock dropout plate 12 of slippaging, because spring pivot 10 is withstood by interlocking connecting levers 7 arc surfaces, combined floodgate semiaxis 11 can not turn clockwise; The motion that is to say closing coil 13 moving iron cores after mechanism closes a floodgate is idle motion, and it can not cause again and close a floodgate.
The above execution mode has only been expressed a kind of execution mode of the utility model, but can not therefore be interpreted as the restriction to the utility model scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection range of the utility model.
