PARTIAL DISCHARGING AND SHORT CIRCUIT DETECTING SYSTEM AND METHOD

摘要

The present invention relates to a system and a method for sensing partial discharging and short circuit, and capable of sensing initial insulation breakdown in a vehicle. The present invention can prevent complete destruction of insulation and the short circuit in advance by monitoring the insulation destruction in the corresponding components with a minute electric field generated from the corresponding components during the early insulation destruction by installing a plurality of sensing units capable of sensing the partial discharging and short circuit in the respective components of electrical power systems of the vehicle. In addition, the present invention can sense initial insulation destruction without adding excessive compositions in comparison with the existing short circuit sensing system by installing the sensing units in the components of the electrical power systems respectively, by connecting the sensing units to a single switching unit and by successively connecting the sensing units from the switching unit to a determination unit, which determines the partial discharging and short circuit according to the selection control signal.
