Description
Technical field
the present invention relates to the improvement of arc generating device structure.
Background technology
reach the various developments that are used for the electrical equipment of arc-detection under the atmospheric conditions in the gaseous arc test, arc generating device all is indispensable, plays crucial effects.But existing arc generating device also can't be implemented more effectively control to electric arc; For example; The patent No. is 200920070997.2 " a kind of arc generating device "; Arc gap only can realize the precision of minimum 1cm, and there is the problem of giving birth to the arc difficulty in this in low pressure short air gap electric arc is used, and also has certain difficulty through the smooth combustion that the size of regulating arc gap is controlled electric arc.
Summary of the invention
the present invention just make to the problems referred to above, a kind of arc gap precision that improves is provided, easy to operate adjustable arc generating device.
are for realizing above-mentioned purpose; The present invention adopts following technical scheme: the present invention includes base plate; Be provided with slide block between the closed slide on its structural feature base plate; The slide block insulating support is provided with float electrode, and float electrode is corresponding with the fixed electorde on the base plate insulating support; Slide block links to each other with handwheel or motor through gear drive.
the invention has the beneficial effects as follows: the present invention is applicable in the gaseous arc test and the various developments that are used for the electrical equipment of arc-detection under the atmospheric conditions; Can control the size of arc gap through motor or handwheel easily; And the precision of arc gap can reach 1 μ m; Thereby whether decision arc length and electric arc can smooth combustions, can carry out quantitative test to arc length to the influence of arc characteristic effectively.
Description of drawings
Fig. 1 is a structural representation of the present invention.
In
accompanying drawing, 1 is base plate, and 2 is the slide block insulating support, and 3 is rail brackets, and 4 is guide rail, and 5 is front-slider; 6 is rear slider, and 7 is tooth bar, and 8 is Large Gear Shaft During, and 9 is motor, and 10 is pinion shaft; 11 is gear drive, and 12 is pinion wheel, and 13 is support, and 14 is handwheel, and 15 is gear wheel; 16 is travel switch, and 17 is slide block, 18 base plate insulating supports, and 19 is float electrode, 20 is fixed electorde.
Embodiment
the present invention includes base plate 1, and the closed slide 4 on the base plate 1 is provided with slide block 17, and slide block insulating support 2 is provided with float electrode 19, and float electrode 19 is corresponding with the fixed electorde on the base plate insulating support 18 20; Slide block 17 links to each other with handwheel 14 or motor 9 through gear drive 11.
described gear drive 11 comprises the tooth bar 7 that is fixed on the slide block 17; Tooth bar 7 is meshed with the gear wheel on the Large Gear Shaft During between the support on the base plate 1 13 8 15; Gear wheel 15 is meshed with the pinion wheel on the pinion shaft between the support 10 12; One end of pinion shaft 10 is provided with handwheel 14, and the other end of pinion shaft 10 is provided with motor 9.
described guide rail 4 is fixed on the base plate 1 with rail brackets 3 respectively.
On the base plate 1 at the two ends of
described guide rail 4, be respectively arranged with the travel switch 16 that can touch slide block insulating support 2, so that apparatus of the present invention are protected; Like this, when float electrode 19 contacts with fixed electorde 20, continue feeding if maloperation takes place, slide block insulating support 2 will touch travel switch 16, thereby cut off control loop, and float electrode can't be moved on; Vice versa.
described motor 9 is a stepper motor, and stepper motor is by Single-chip Controlling.
described slide block 17 is made up of the front-slider on the guide rail 45, rear slider 6; Can make the stable spacing of maintenance between the guide rail 4.
The material of
described slide block insulating support 2 and base plate insulating support 18 is a polytetrafluoroethylmaterial material.
described float electrode 19, fixed electorde 20 all parallel with guide rail 4.
principle of work of the present invention is following: during use, the input end of power supply links to each other with float electrode 19, fixed electorde 20 respectively with output terminal; After circuit was connected, by the rotation that single-chip microcomputer comes the control step motor, stepper motor moved slide block 17 through gear drive 11 backward, and float electrode 19 and fixed electorde were opened in 20 minutes; So between float electrode 19 and fixed electorde 20 punch-through takes place, produce electric arc then, then, through controling the size of arc gap, to confirm that arc length and smooth combustion situation are until reaching requirement of experiment.
in the big arc gap of needs and to the not high situation of accuracy requirement under, can directly utilize handwheel 14 to replace stepper motors 9 to control the size of arc gap, can increase or reduce arc gap fast, its process is consistent with motor 9 control procedures.
the present invention is as a kind of adjustable arc generating means; Float electrode 19 can realize reliable and stable rectilinear motion accurately; Also can realize the complete procedure of the blow-out of development under big gap (opening distance) in the electric arc generation under the μ m level minim gap (opening distance), little gap (the opening distance); For see from microcosmic, boundary three dimensions electric arc until macroscopic view with switch off time dynamic evolution history variations of physical parameters identification experiment porch is provided, can guarantee the accurate quantitative test of (blow-out electric current, arc voltage, blow-out time) of three dimensions electric arc external characteristics parameter simultaneously.
