Abstract

The utility model provides a discharge electrode, it includes main electrode and auxiliary electrode, and the diameter of auxiliary electrode tip is greater than the diameter of main electrode tip. The utility model discloses in use, owing to adopt protruding cooperation to sharp electrode, the auxiliary electrode is ablated, easily forms the concave head, and main electrode is to the centering nature of auxiliary electrode like this, can not produce the bypass and discharge, and the voltage waveform of discharging is stable and voltage wave amplitude is high, and electric shock efficiency improves greatly, and main electrode, auxiliary electrode consume little moreover, the life extension of electrode.

Description

Sparking electrode

The utility model relates to a kind of sparking electrode, good to neutrality, difficult bypass arcing, the long sparking electrode of electrode life of producing of especially a kind of discharge.

Sparking electrode is to main electrode with certain interval and auxiliary electrode, and at logical positive negative electricity of moment, main electrode and auxiliary electrode have generating positive and negative voltage respectively and explode in moment conducting, generation, thereby utilize electrode discharge to produce shock wave.If the end intended diameter of electrode is bigger, be convex, it is bad to neutrality to discharge, and often is easy to produce the bypass arcing, and voltage waveform is extremely unstable.Therefore, concentrate for the electrical discharge arc aligning, electric arc forms and does not disperse, discharged preferably to neutrality, do not produce the discharge arcing, existing electrode structure generally is that the end with main electrode and auxiliary electrode is designed to the pointed of same diameter, and sharp as much as possible, the shape of formation tip to tip.But in use, the structure of tip to tip is after producing discharge, and electrode tips is often very fast ablated, and out-of-shape, and electrode gap increase use a period of time just to have to scrap, and consumption of electrode is big.Simultaneously, the structure of electrode no longer is the tip to tip discharge, and produces bypass arcing phenomenon often when discharge like this, the so not only efficient decline of the discharge of electrode, and the voltage waveform that the discharge back forms disperses, and useful life is shorter.

The purpose of this utility model is to provide a kind of sparking electrode, and its electrode discharge can keep relatively-stationary gap, and it is good to neutrality to discharge, and is difficult for producing the bypass arcing, discharge voltage waveform stabilization and voltage wave panel height, and electrode life is long.

The purpose of this utility model is achieved in that a kind of sparking electrode, and it comprises main electrode and auxiliary electrode, and the diameter of auxiliary electrode end is greater than the diameter of main electrode end.

According to the technique scheme analysis as can be known, the utility model in use, because adopt protruding cooperation to sharp electrode, auxiliary electrode is ablated, easily forms recessed head, like this main electrode to auxiliary electrode to neutrality, can not produce the bypass discharge, discharge voltage waveform stabilization and voltage wave panel height, electric shock efficient improves greatly, and main electrode, auxiliary electrode consume for a short time, and prolong the useful life of electrode.

Below in conjunction with accompanying drawing and specific embodiments the utility model is described in further detail.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the partial structurtes schematic diagram of the utility model after use a period of time.

Referring to Fig. 1, the utility model is a kind of sparking electrode, and it comprises main electrode 1 and auxiliary electrode 2, and the diameter of auxiliary electrode end 3 is greater than the diameter of main electrode end 4.Auxiliary electrode 2 ends 3 are protruding, and main electrode 1 end 4 is a point, thereby forms protruding pair to point, main electrode structure.

The utility model in use, owing to adopt protruding cooperation to point pair, main electrode 1,2, auxiliary electrode end 3 is ablated after electric shock, easily form concavity, as shown in Figure 2, when the main electrode 1 relative auxiliary electrode 2 of point point discharges like this, all be auxiliary electrode 2 ends 3 electric shocks that concavity is aimed in pointed main electrode 1 end 4, discharge neutrality is ensured no longer produces the bypass discharge like this, so discharge voltage waveform stabilization, and the raising of voltage wave amplitude, the blown-out shot rate descends, and electric shock efficient improves greatly, and main electrode 1, auxiliary electrode 2 losses are little, and prolong the useful life of electrode.
