Abstract

The invention discloses an arc generating device for testing an electric switch contact material, relating to an arc generating device. The invention solves the problem that the arc generating device for testing an electric switch contact material does not exist at present. One end of each guide rail is fixed on a position block; the other end of the guide rail is inserted in an adjusting block and is in slip connection with the adjusting block; a gap is reserved between the lower end surface of the adjusting block and the upper end surface of a bottom plate; a first insulating plate is fixed on the upper end surface of the position block; a second insulating plate is fixed on the upper end surface of the adjusting block; a first jig is arranged on the upper end surface of the first insulating plate; a second jig is arranged on the upper end surface of the second insulating plate; and the upper end surface of the first insulating plate and the upper end surface of the second insulating plate are at the same level. The arc generating device is suitable for testing AC / DC arc characteristics of different contact materials and can facilitate analyzing the influence of factors of arc length, power supply voltage, load characteristic, load strength and the like on the stable burning point of the arc.

Description

technical field [0001] The invention relates to an arc generating device, in particular to an arc generating device for testing electrical switch contact materials. Background technique [0002] High reliability and long life are the development direction of electrical switches. However, the arc discharge between electrical switch contacts leads to ablation of electrical switch contact materials, which directly affects the reliability and service life of electrical switches. The relationship between arc voltage and arc current is an important characteristic curve used to describe arc discharge. The DC arc static voltage and current characteristic curve represents the characteristics of the arc burning in a steady state, that is, when the current intensity and arc length are constant, or only change slowly. Although the conditions of the static arc characteristic curve are usually not met in electrical switches, it can not only be used as the basis for studying the dynamic v...
