The utility model is a kind of withdrawable circuit breaker position signal acquisition and transmitting device, comprises secondary terminals sub-loop bearing and breaker body, it is characterized in that: on the described secondary terminals sub-loop bearing electric wire connecting junction that contains sensitive switch is installed at least; A trigger board is installed on the described breaker body at least; Described trigger board triggers the sensitive switch in the electric wire connecting junction in the process that moves with breaker body, make sensitive switch produce the signal of expression breaker body position.
Describe in detail below in conjunction with accompanying drawing.
Ask for an interview Fig. 1, electric wire connecting junction 1 has a housing 11, be provided with 2 pillars 113 in the housing 11, two borehole jacks on the sensitive switch 7 are on pillar 113, for sensitive switch 7 provides correct installation site, on left and right, last three directions of sensitive switch 7 barricade is arranged all, prevent moving of sensitive switch 7, on common port 71 welding leads 8 of sensitive switch 7, two contact chips 9 of the lead 8 and the outside weld mutually, the other lead 81 of leading-out terminal 72 welding of sensitive switch 7, lead 81 welds mutually with two inboard contact chips 9.
Also be provided with pillar 111 on the housing 11 of electric wire connecting junction, the root of pillar 111 has the triggering boss 115 that exceeds, driving lever 4 has axis hole 43, driving lever 4 is enclosed within on the pillar 111 hinged with pillar 111 by its axis hole 43, an end face of driving lever 4 contacts with triggering boss 115, guaranteed that driving lever 4 contact area with pillar 111 in motion process is little, make driving lever 4 motions more flexible, the shoulder 42 of driving lever 4 contacts with the afterbody 52 of push rod 5, the shape of the opening 114 of housing 11 lower ends is rectangular, driving lever 4 is by pack into 11 li of housings of opening 114 parts, and opening 114 parts have just prevented the excessive amount of motion of driving lever 4 like this.There is the shoulder 42 that promotes pushrod movement at the two ends of driving lever 4, and this shoulder 42 is arbitrarily angled with 41 one-tenth of ends.
Electric wire connecting junction also comprises an end cap 3, and guide pillar 32 is arranged on the end cap 3, directly inserts in the hole of housing 111, and interference fits is adopted in guide pillar 32 and hole, prevents that end cap 3 from coming off out from housing 11.The inboard of end cap 3 is provided with barricade 31.
The process of existing butted line device collection and transmission signals is further described.Referring to Fig. 3-Fig. 5, trigger board 2 on diagram 3 position, the end 41 that first end face 21 of trigger board 2 front ends promotes driving levers 4, this is the position that begins most.Trigger board 2 along with breaker body in the drawer back moving process, the shoulder 42 of driving lever 4 promotes the end face 52 of push rod 5, push rod 5 is moved in the chute 116 of housing 11, and compression spring 6 energy storage, when push rod 5 arrives position shown in Figure 4, the contact that triggering boss 51 on the push rod 5 touches sensitive switch 7, sensitive switch 7 is triggered, by the lead 8 that its common port is connected with output the signal feedback of on-state is gone out, this signal also is the signal of separation point position, and after trigger board 2 continued to move with breaker body, driving lever 4 continued stressed, after causing the triggering boss 51 of push rod 5 to move past sensitive switch 7, contact on the sensitive switch 7 is released, and the end 41 of driving lever 4 is positioned on the upper surface 24 of trigger board 2, the end 41 of driving lever 4 is shaped on cambered surface, can reduce the friction in motion process.After trigger board 2 continues to move, second end face 22 of trigger board 2 front ends begins to promote the driving lever in the another one electric wire connecting junction, moves, trigger the sensitive switch in second electric wire connecting junction after, this electric wire connecting junction comes out the signal feedback of on-state, and this signal also is the signal of test position.Breaker body continues motion, and is when arriving link position, no longer mobile.The 3rd end face 23 of trigger board 2 front ends promotes the driving lever of the 3rd electric wire connecting junction, cause the push rod of this electric wire connecting junction to trigger inner sensitive switch, the signal feedback of link position is come out, and at this moment, the driving lever of two other electric wire connecting junction is all on the upper surface 24 of trigger board 2 (Fig. 5).So far, finished the collecting work of three position state signals.Wherein: Fig. 6 when gathering the detached position signal, the residing position of driving lever in three electric wire connecting junctions; Fig. 7 when gathering the experiment position state signal, the residing position of driving lever in three electric wire connecting junctions; Fig. 8 when gathering the link position status signal, the residing position of driving lever in three electric wire connecting junctions.
When breaker body begins (shifting out) when mobile in the other direction from drawer, the push rod 5 of the 3rd electric wire connecting junction (electric wire connecting junction of Chu Faing at last) is released under the effect of energy at back-moving spring 6, the beginning rightabout moves, and the contact of release sensitive switch 7, at this moment, driving trigger board 2 as breaker body continues to move, the compression spring is released and can be promoted push rod 5 in second electric wire connecting junction, the end face 52 of push rod 5 promotes the shoulder 42 of driving lever, when trigger board 2 moves to certain position, face 41 contacts with face 22 again, and move along with moving of face 22, trigger the contact of sensitive switch once more, if trigger board 2 continues to move, the sensitive switch contact of second electric wire connecting junction can be released, and the driving lever face 41 of first electric wire connecting junction can contact again with face 21, and triggers the contact of its inner sensitive switch once more, along with moving of trigger board 2, the contact of sensitive switch is released once more, gets back to initial position up to trigger board 2.
The cross-sectional area shape of the triggering platform at above-mentioned push rod top can be any one in rectangle, square, trapezoidal, circular, the semicircle.In the shape semicircular in shape of the end of driving lever, ellipse, the irregular smooth transition curved surface any one.Consult Fig. 2,1 three of electric wire connecting junctions are one group, form the three-position signal acquiring module.Fig. 9 represents that the three-position signal acquiring module is installed on the both sides of secondary terminals sub-loop bearing, and trigger board 2 is installed in the plug bond seat both sides of this body support frame.
