Problems solved by technology
[0005] In view of this, what this application intends to solve is that the drive of the motor in the conventional technology is inconvenient to control, it is difficult to control the moving speed and distance of the sliding block, and the characteristics of the arc are related to the material. It is also inconvenient to replace, and when the arc is small, it is difficult to directly observe the technical problems

Embodiment Construction
[0031] The implementation of the present application will be described in detail below with reference to the accompanying drawings and examples, so as to fully understand and implement the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects.
[0032] Such as figure 1 - As shown in 7, a high-safety arc characteristic detection device of the present invention includes a detection box 1, a detection box door is installed on the detection box 1, and the lower part of the front of the detection box 1 is an opening structure, and the two sides of the opening structure are fixed Two groups of slide rails 17 are installed, and the detection box door is slidably installed in the two groups of slide rails 17. The detection box 1 is a non-transparent structure. When testing, the detection box 1 is in a closed state. When the detection strip 15 is active, it can directly slide upwards and open the detection b...

The invention discloses an arc characteristic detection apparatus high in safety. The apparatus includes a detection case. The detection case is provided with a detection case door. A fixed cylinder is fixedly arranged on a bottom plate inside the detection case. A fixed detection bar is detachably arranged in the fixed cylinder. A rotary ring is arranged on the top of the detection case in a rotatable manner. During installation of a movable detection bar, a protective cover is made to slide upwardly, the mouth of a V-shaped spring clip is open, the movable detection bar is put into the V-shaped spring clip, the protective cover is loosened and slides downwardly under the effect of spring elastic force, and the mouth of the V-shaped spring clip is closed to clamp the movable detection bar. During detection, the detection case stays in a closed state, a rotary screw rod can drive a ball sleeve to slide on the rotary screw rod when rotating, and the ball sleeve can drive a supporting ring to move up and down when sliding on the rotary screw rod.
Description
technical field [0001] The present application belongs to the field of electric arc technology, and in particular relates to a highly safe electric arc characteristic detection device. Background technique [0002] Arc is a gas discharge phenomenon, the instantaneous spark generated by the current passing through some insulating medium (such as air). The arc is a kind of self-sustaining gas conduction (electrical conduction in ionized gas), and most of its carriers are electrons generated by an electron emission. ) leads to the escape of electrons, and the gas atoms or molecules in the gap will generate electrons and ions due to ionization (impact ionization, photoionization and thermal ionization). In addition, electron or ion bombardment of the emitting surface causes secondary electron emission. When the ion concentration in the gap is high enough, the gap is broken down by electricity and an arc occurs. [0003] The high temperature of the arc may burn out the electri...
