Description
Technical field
The utility model belongs to the primary cut-out field, is specifically related to a kind of indicating device of primary cut-out.
Background technology
On the divide-shut brake indicating structure of primary cut-out, have a variety of; For example: liquid crystal display, rectilinear motion indication etc.; But these indications exist some significant disadvantages: volume is big, complex structure, stability are not high, so on some switchgears, just can't adopt these traditional indicating mechanisms.
Summary of the invention
The high-voltage circuit-breaker switching on-off indicating mechanism of requirements such as the purpose of the utility model provides a kind of simple in structure, and is reliable and stable, and volume is little, non-maintaining.
The technical scheme that realizes above-mentioned purpose is: a kind of indicating device of primary cut-out is characterized in that: mainly comprise base plate, close the branch indicator board, rotation axis, torsion spring, back shaft, supporting seat, main display box, lever and on/off switch controlling organization; One end of base plate is fixed with supporting seat; One end of supporting seat is connected with rotation axis, and torsion spring is nested with outside rotation axis, and an end of torsion spring is fixedly connected rotation axis; One end of the other end of torsion spring and lever is fixedly connected; The end below that lever is fixedly connected with torsion spring also is fixed with closes the branch indicator board, and the stiff end that closes the branch indicator board also links to each other with base plate through fulcrum shaft, and the on/off switch controlling organization places a side of base plate; The other end of lever links to each other with the on/off switch controlling organization, and the other end of base plate is provided with main display box.
The utlity model has simple in structure, reliable and stable, advantage such as volume is little, non-maintaining.
Description of drawings
Fig. 1 is the front view of the utility model;
Fig. 2 is the vertical view of the utility model.
Embodiment
Like Fig. 1, shown in 2, a kind of indicating device of primary cut-out mainly comprises base plate 1, supporting seat 2, on/off switch controlling organization 3, lever 4, closes branch indicator board 5, back shaft 6, rotation axis 7, torsion spring 8 and main display box 9.
Be fixed with supporting seat 2 on the base plate 1; One end of supporting seat 2 is connected with rotation axis 7, and torsion spring 8 is nested with outside rotation axis 7, and an end of torsion spring 8 is fixedly connected rotation axis 7; One end of the other end of torsion spring 8 and lever 4 is fixedly connected; The end below that lever 4 is fixedly connected with torsion spring 8 also is fixed with closes branch indicator board 5, and the stiff end that closes branch indicator board 5 also links to each other with base plate 1 through fulcrum shaft 6, and on/off switch controlling organization 3 places a side of base plate 1; The other end of lever 4 links to each other with on/off switch controlling organization 3, and the other end of base plate is provided with main display box 9.
The operation principle of the utility model is:
When the switchgear separating brake; When on/off switch controlling organization 3 moves downward along its axial straight line; Lever 4 is rotated by the effect of the tension force of torsion spring 8 moving axis 7 clockwises that rotate; Drive the coupled branch indicator board 5 that closes that connects and be rotated counterclockwise motion, when its stroke finishes, show in the main display box 9 of base plate 1 " branch " around fulcrum shaft 6.
When switchgear closes a floodgate; On/off switch controlling organization 3 moves upward along its axial straight line; On/off switch controlling organization 3 drives levers 4 moving axis 7 that rotates and rotates counterclockwise; The coupled branch indicator board 5 that closes of the lower end of lever 4 drive simultaneously clockwise rotates around fulcrum shaft 6, after its stroke finishes, is shown as " closing " in the main display box 9 of base plate 1.
