Embodiment
As shown in Figure 1, the current collector of low tension switch 1 is supported on the axle 2 of switch shaft 3 the axle dress.Switch shaft itself is supported on the central cassette, and this does not draw.Switch shaft 3 has planet axis relative on diameter 4 and 5, and when switch shaft 3 rotated around axle 2, they also rotated.Axle 4 is point of applications that toggle connects connecting rod 6, and its other end is connected to second toggle flexibly and connects on the connecting rod by toggle connecting axle 7, and wherein second toggle connects the shape that connecting rod forms triangular element 8.By axle 9, triangular element 8 is connected on the ratchet bar 10 on second angle flexibly, and ratchet bar 10 is used for the excessive current of release-push latch, and axle is supported on the fixing axle of arranging 11 with adorning.
Can sum up particularly in Fig. 2 and 3, triangular element 8 comprises the plate of two symmetries, parallel to each other stretching out, and between them, ratchet bar 10 is received and is supported on the connecting axle 9, and connecting axle 9 is connected with plate is fixed to one another.Zone at the 3rd angle of triangular element 8, plate connects by pin 12, wherein sells 12 and can contact ratchet bar 10, limits moving of triangular element 8.
As has already been mentioned above, each toggle connects connecting rod 6 owing to symmetry, is provided at the both sides of therebetween triangular element 8 and ratchet bar 10, and toggle connection connecting rod 6 is connected to each other by axle 7.The drive rod 13 of three-dimensional display partly in Fig. 2 comprises two plates, on plane separately, stretches out from two side plates 15 that drive box, and its bottom 13a that shows among Fig. 4, be supported in flexibly on the corresponding support part 14 that drives box side plate 15.In this embodiment, drive rod 13 comprises a veneer, bends on the coupling part in U type mode, and the bolt 16 and the driving handle 17 of coupling part are fixed, and wherein driving handle 17 is from driving the box protrusions.In each side of triangular element 8, a driving spring 18 is arranged in the toggle connecting bolt of conduct axle 7, and between the bolt 16 of drive rod 13.The bottom 13a of box side plate 15 and drive rod 13 also is arranged in the both sides of triangular element 8.
Releasing device is by reference number 9 indications in Fig. 1, and by this releasing device, control discharges ratchet bar 10 in known manner.
At the closing positions that Fig. 1 and 4 shows, driving handle 17 is positioned at the position that tilts to the left side, makes the dynamic effect line of spring 18 run to the left side of axle 9.At closing position, because spring force uses by triangular element 8 and axle 9, ratchet bar 10 is owing to cooperates with releasing device 19, and can not carry out anticlockwise moving up, so spring force becomes triangular element 8 around 9 moving clockwise.For this reason, as mentioned above, axle 7 is forced to intersect with the line of axle 9 connecting axles 4, if this causes ratchet bar 10 closures, on the closing direction of current collector 1, toggle connects connecting rod 6 and acts on switch shaft 3.
Fig. 5 has shown the operating position that discharges.After ratchet 10 was released device 19 releases, low tension switch arrived this operating position.At this operating position, driving handle 17 occupies the position that Fig. 5 shows.Owing to be applied on the axle 7 in this position spring power, triangular element 8 connects upwards pulling of connecting rod 6 with ratchet bar 10 and toggle, and wherein 10 of ratchet bars are contained on the triangular element 8, and this causes switch shaft 3 to rotate, and causes current collector 1 to separate like this.
The contact fusing may take place in operating process, and this may cause, the tensile force that can not only use owing to spring 18, and realize the separation of contact 1.Fig. 6 has shown the situation that such releasing device 19 closes a floodgate.If such situation takes place, can not determine from the position of driving handle 17 so whether the contact separates.In order only to pass through the mode of the position of driving handle 17, determine the practical operation situation of contact, the design of switch of the present invention has shown some characteristics, they will be explained in the back.
Can sum up from the demonstration of Fig. 1 and 4, securing rod 20 be arranged in the outside of one or two side plate 15 that drives box, an end axle of securing rod 20 is contained on the planet axis 5 of switch shaft 3, and other end axle is contained on the fixing pin 21.Pin 21 is fixed on the side plate 15, and by slotted hole 22 guiding, wherein slotted hole 22 is formed in the securing rod 20.In the end of securing rod 20 slotted holes one side, form projection 23, it can cooperate with receiving unit 24, and wherein receiving unit 24 is formed in the drive rod 13.Because this design, Fig. 7 has shown the driving handle 17 indicating contacts 1 absolute final trip position that separates, and this position is prevented from the mode of back.
At first, driving handle 17 moves in the clockwise direction, cooperates up to part 24 and 23.When attempting to be moved further driving handle 17 on this direction, the result impacts from driving handle 17, is applied directly on the securing rod 20 by drive rod 13, and the moment of torsion of Chan Shenging acts on the switch shaft 3 by axle 5 in the clockwise direction like this.Because axle is relative short distance between 2 and 5, this moment of torsion is very little, so in the contact 1, by the separation resistance that little fusing produces, can know on driving handle 17 that the face of land is revealed.Thus, any personnel that attempt cut-off switch can recognize at once, and driving handle 17 can not be pulled trip position at once.
If contact 1 is not melted to together, securing rod 20 occupies the position that Fig. 5 shows, makes driving handle 17 with drive rod 13, can freely move to the final trip position that Fig. 7 shows.By this way, the pin 25 that is applied on the driving handle 13 cooperates ratchet bar 10, pushes the latter in the clockwise direction downwards, occupies the stopper position of releasing device 19 up to ratchet bar 10.
Switch is combined with drive rod 13, drive rod 13 can be driven handle 17 and drive, and act on toggle coupling part 6,7 and 8 by driving spring 18, at the switch shaft 3 that is used for contact-actuating 1 and be used to control between the ratchet bar 10 that discharges excessive current, the exercisable connection set up with 8 in described toggle coupling part 6,7.Switch also has securing rod 20, and it and drive rod 13 interact, and when 1 closure of contact, prevent that driving handle 17 from moving to trip position, wherein when 1 closure of contact, by the rotation of switch shaft 3, securing rod 20 can automatically be pulled the latched position that is relevant to drive rod.
