DEVICE FOR MECHANICAL STRENGTH TESTS OF CONDUCTORS INSULATION

摘要

A device for mechanical strength tests of conductors by means of frictions one conductor surface with another conductor and determination of the time after which conductors become damaged. To determine isolation resistance (a wear rate of isolation depending on a current value and a pressure betweenconductors) coils of testing conductors are located on a magnetic core with overlapping one coil with another so that lower coil overlaps with upper coil with possibility of current control and measuring of the pressure between conductor using dynamometer fixed to upper coil and to a base where the magnetic core is disposed.
