GB/T1411-2002 dry solid insulating material resistance to high voltage, small current arc discharge test (equivalent to IEC and ASTM D495 and other standards; in line with UL 746A and other test methods
Functional principle
Insulating materials to resist deterioration caused by high-voltage arc action, usually with a standard arc flame on the surface of the material caused by charring to the surface conductivity and the arc disappeared the time required to express the unit of seconds in the plate specimen plus two separated by a certain distance from the tungsten electrodes, depending on the need for high-frequency high-voltage current between the two poles to produce an arc, initially intermittent time is gradually shortened, and finally for the continuous arc and gradually increase the current, the material The material is subjected to gradually harsh arc conditions and eventually cause damage. Arc resistance for high-voltage switch or low-voltage high-current switch insulating materials have important significance, because in the switch opening and closing will often be subjected to arc action, only good arc resistance materials can be selected.
In electrical and electronic equipment within the insulating material when it is exposed to high voltage, small current arc discharge, between them to withstand the initial difference in the immediate surface damage occurs, arc discharge caused by local thermal and chemical decomposition and corrosion and ultimately in the insulating material on the formation of conductive channels, when the formation of conductive channels within the material under test, it can be determined that the material has failed.
