Functional features

Insulation materials have the ability to resist deterioration caused by high voltage arc action,usually a standard arc flame is used to induce carbonization on the surface of the material until the surface is conductive.The time required for the arc to disappear is expressed in second. Add two tungsten electrodes separated by a certain distance on the plate sample, at first the arc is intermittent, then gradually shortened,and finally continuous arc with gradually increasing current,the material is subjected to increasingly severe arc conditions and eventually fails.Arc resistance is important for insulating materials used in high-voltage switches or low-voltage high-current switches,because the switch is often affected by arc when it is opened and closed, only materials with good arc resistance can be selected.
Insulating material used in the interior of electrical and electronic equipment, when exposed to a high-voltage, low-current arc discharge, is tested the differences in surface damage close to the arc.The arc discharge causes local thermal and chemical decomposition and corrosion and eventually forms a conductive channel on the insulating material,When a conductive channel is formed in the tested material, the material can be determined to have failed.
Arc resistance tester is GB1411, IEC61621, ASTMC495, UL746A and other standards of the simulation safety test project necessary special instrument.
The arc resistance tester is composed of electrical schematics and electrodes according to the following standard requirements
