Abstract:

The function of oscillation circuit regulation in the low-voltage electric apparatus breaking test is expounded.The requirements of relevant standards for these parameters and the connection method of adjustment circuit are listed.Through the analysis of the test results under the different oscillation regulation combinations,it shows that the oscillation frequency regulation can be used to avoid the reignition phenomenon of the product in the test,and the oscillation coefficient regulation can be used to limit the maximum arcing voltage.The method of regulating oscillation circuit is provided for relevant technicians.

Key words: low voltage electric apparatus, breaking capacity, oscillation frequency, over oscillatory coefficient
