Abstract
The utility model discloses a three-position electric signal output device of a circuit breaker, which comprises a rotation shaft, a cam, a dragging plate, a rocking handle shaft, an installing plate, a microswitch and a three-position indicating lamp. The rocking handle shaft is operated to rotate to drag the dragging plate to translate, and a rack arranged in a dragging plate groove pushes a sector gear to drive the rotation shaft to rotate, so that the cam arranged at the end part of the rotation shaft can rotate; and when the corresponding microswitch is pressed, the three-position indicating lamp connected with the microswitch is started to give out indicating signals with different colors so as to display three working states of the circuit breaker. The three-position electric signal output device has a reasonable structure, is operated simply and conveniently, and has reliable performance.
Description
Technical field
The utility model relates to a kind of circuit breaker three position output device of the electrical signal, belongs to low-voltage electrical apparatus manufacturing technology field.
Background technology
At present; The output device that in circuit breaker, is used for the three position signals of telecommunication; Normally drive slide block, through translational motion, depress the guiding shell fragment of sensitive switch and realize what the signal of telecommunication was exported in the gathering sill on device by the connecting rod that is fixed on the circuit breaker drawer base slide plate.This three position output device of the electrical signal complex structures, amount of parts is many, and assembles loaded down with trivial details; In addition,,, will increase the assembling difficulty of processing, raise the cost if it is meticulous small and exquisite to pursue structure because of receiving the restriction of space factor.In addition, on mechanical structure, owing to adopt slide block and shift fork linkage to drive; Slide block is connected through bolt and nut with the shift fork linkage; Gathering sill is a double flute, will cause stuckly if a certain amount of deflection appears in slide block mechanism, causes the slide block can't proper motion; Cause breaker body can't shake into or shake out, thus very easily accidents caused.
Summary of the invention
To the problem that above-mentioned technology exists, the purpose of the utility model provides a kind of circuit breaker three position output device of the electrical signal of rational in infrastructure, easy and simple to handle, dependable performance.
For realizing above-mentioned purpose, the utility model has been taked following technical scheme:
The described a kind of circuit breaker three position output device of the electrical signal of the utility model; Constitute by rotating shaft, cam, planker, crank shaft, mounting panel, sensitive switch, three position indicators; It is characterized in that described cam is arranged at the end of rotating shaft, in rotating shaft, a pair of sector gear is installed; On the described planker, be provided with two planker grooves that match with sector gear, be provided with tooth bar in the planker groove, planker is installed in an end of crank shaft, and crank shaft is installed on the drawout chassis.Described sensitive switch is arranged on the mounting panel, and sensitive switch adopts lead to be connected with three position indicators.
As preferably, the described cam that is arranged at roller end is the monolithic construction with three cam heads, and three cam heads are step and distribute, and is 30 ° and staggers each other.
As preferably, the described sensitive switch quantity that is arranged on the mounting panel is three, is the axially-aligned setting, and corresponding with three cam heads that are arranged at roller end.
As preferably, described three position indicators are installed in through lead on the housing of circuit breaker or in the central control room.
The utility model through after the above-mentioned design is rational in infrastructure, easy and simple to handle, and it promotes the planker translation through handling the rotation of crank shaft; Tooth bar by being arranged in the planker groove promotes sector gear driving rotating shaft rotation; Make the cam rotation that is arranged at roller end, depress corresponding sensitive switch, startup is attached thereto the index signal that three position indicators that connect send different colours; Show three different working states of circuit breaker, so its performance is very reliable.

Embodiment
Below in conjunction with accompanying drawing, the technical scheme of the utility model is further specified, but be not restriction the utility model protection range.
Like Fig. 1, shown in Figure 2, the described a kind of circuit breaker three position output device of the electrical signal of the utility model are made up of rotating shaft 2, cam 6, planker 4, crank shaft 5, mounting panel 7, sensitive switch 8,9 of three position indicators, and cam 6 is arranged at the end of rotating shaft 2; In rotating shaft 2, a pair of sector gear 3 is installed; On the described planker 4, be provided with two planker grooves that match with sector gear, be provided with tooth bar in the planker groove, planker is installed in an end of crank shaft 5, and crank shaft 5 is installed on the drawout chassis 1.Described sensitive switch 8 is installed on the mounting panel 7, and sensitive switch 8 adopts lead to be connected with three position indicators 9.
The described cam that is arranged at roller end 6 is for having the monolithic construction of three cam heads, and three cam heads are step and distribute, and is 30 ° and staggers each other.
Described to be arranged at the sensitive switch quantity that is installed on the mounting panel be three, is the axially-aligned setting, and corresponding with three cam heads that are arranged at roller end.
Described three position indicators 9 adopt green, yellow, red three kinds of color showings " separation ", " test ", " connection " three kinds of states respectively.Three position indicators 9 are installed on the housing of circuit breaker through lead or in the central control room, it can carry out the remote signal transmission.
The concrete working method of the utility model realizes like this:
Described a kind of circuit breaker three position output device of the electrical signal and the breaker bodies of the utility model; The dropout synchronous working is begun by the released state outermost end, and cam 6 is depressed first sensitive switch 8 that is fixed on the mounting panel 7; Green light is bright, and circuit breaker is in the mask work state; When crank shaft 5 rotates; Planker 4 is pushed ahead, and the sector gear 3 that the tooth bar in the planker groove of planker 4 promotes in the rotating shaft 2 rotates, and makes rotating shaft 2 rotations; The cam 6 that is arranged on the roller end also rotates thereupon; When cam 6 turned an angle, first cam head on the cam 6 left first sensitive switch, and the green indicating lamp in three position indicators 9 extinguishes; When crank shaft 5 rotates once more; Cam 6 turns an angle thereupon, when second cam head of cam 6 depressed second sensitive switch 8 that is fixed on the mounting panel 7, at this moment; Yellow indicator lamp in three position indicators 9 is bright, and the expression circuit breaker is in trystate; When crank shaft 5 rotated once more, the cam 6 that is arranged on the roller end turned an angle thereupon, and when second cam head on the cam 6 left second sensitive switch, the yellow indicator lamp in three position indicators 9 extinguished; When crank shaft 5 rotates once more; Drive cam 6 and turn an angle, and when making the 3rd cam head on the cam 6 depress the 3rd sensitive switch that is fixed on the mounting panel 7, at this moment; Red led in three position indicators 9 is bright, and the expression circuit breaker is in connection status.
Repeat above-mentioned action, the described three position output device of the electrical signal of the utility model just can accurately show three states of circuit breaker.
