Description
Technical field
The present invention relates to the experimental technique field, the device of electric arc test under the particularly electric sliding contact state.
Background technology
In the electric sliding contact of high speed, electric arc is a kind of very harmful atmospherical discharges phenomenon, as the electric locomotive field.Existing arc-detection mainly is static measurement, as the discharge test in the high-potting etc.Electric arc in the static arc test mostly is macroscopic, with the electric arc that produces in the electric sliding contact of high speed a great difference is arranged, and electric arc is the starting the arc in narrow slit, because relative motion fast, arc extinguishing fast belongs to quick astable electric arc again after the starting the arc.And the electric sliding contact of line style, contact interface constantly changes, so Direct observation, to measure contact condition very difficult.Moreover the factor that influences contact condition is a lot, as contact pressure, sliding speed, size of current, voltage swing etc., is difficult to directly set up the corresponding relation of influence factor and contact condition.So it is more rare to the detection research of electric sliding contact of this type of high speed and electric arc at present.
Summary of the invention
The purpose of this invention is to provide the device that electric arc is tested under a kind of reliable high speed electricity sliding contact state, be difficult to the problem that the electric arc that produces in the electric sliding contact of high speed is tested in order to the solution prior art.
The solution of the present invention is: the device of electric arc test under the electric sliding contact state of high speed, comprise a metal rolling disc, the vertical rotation dish is provided with at least one metallic pin, rolling disc, metallic pin and testing power supply form the detecting electric loop, and the corresponding position of each metallic pin and rolling disc is equipped with the light activated element that is used to detect arc stiffness.
Further, the vertical rotation dish is provided with two metallic pins, and two metallic pins relatively rotate the dish center of circle and are symmetrically distributed.
Further, string is established a reometer in described detecting electric loop, is provided with voltage table between rolling disc and the metallic pin, and described reometer is connected an electric current and voltage wave recording device with voltage table output.
Further, the described light activated element that is used to detect arc stiffness is a phototriode.
Proving installation provided by the invention is that linear slide is converted into circumferential slippage, thereby can carry out the measurement of electric sliding contact of high speed and electric arc easily.The employing device structure is simple, hardware requirement is low, easy realization, and the result is accurate, the reliability height.Adopt light activated element to detect arc stiffness, adopt electric current and voltage wave recording device survey record voltage and electric current.Overcome and only used the deficiency of photoelectric sensor aspect measurement nonstatic electric arc, measurement result is accurate, reliability is high.

Embodiment
The present invention will be further described in detail below in conjunction with accompanying drawing.
The device of electric arc test under a kind of high speed electricity sliding contact state as shown in Figure 1, comprise a metal rolling disc 3, it can be a plurality of that the vertical rotation dish is provided with two relative metallic pin 2(, the axle center of Moving plate evenly distributes but requirement rotates, satisfy requirement for dynamic balance), two metallic pins 2 are pressed on the rolling disc.The effect that correspondence is provided with two metallic pins is to adjust rotary balance.An electric current and voltage wave recording device is set, two test sides of this electric current and voltage wave recording device are connected (metallic pin and rolling disc and a constant current source formation loop respectively with two metallic pins, 2 conductions, the purpose of wave recording device is the electric current of test loop and the voltage between the friction pair, so two test sides of wave recording device can be connected on two metallic pins, also can one be connected on the metallic pin, another is connected on the rolling disc); Each metallic pin 2 is equipped with the phototriode 1 that is used to detect arc stiffness with the corresponding position of rolling disc 3.When experimentizing, phototriode 1 is arranged near the contact position.
After proving installation is ready to, energising and make the rolling disc high speed rotating, at first by voltage, electric current under the electric current and voltage wave recording device survey record sliding contact state, by phototriode 1 survey record electric arc situation, can draw out the oscillogram of voltage, electric current and electric arc, integrated voltage, electric current and electric arc information are carried out the judgement of electric sliding contact state then: no electric arc, and voltage, electric current variation tendency are identical, be judged to be stable electrical sliding contact state, as Fig. 2; Electric arc is arranged, and voltage, electric current variation tendency are inequality, then are judged to be starting the arc state, as Fig. 3; No electric arc, voltage, electric current variation tendency are inequality, then are judged to be complete disengaged condition, as Fig. 4 (among the figure, electric arc, voltage waveform are overlapping).
