REMOTE INSULATION-RESISTANCE MEASURING APPARATUS AND METHOD

摘要

The present invention relates to a remote insulation-resistance measuring apparatus adapted to allow insulation resistance to be measured remotely before a stopped backup motor takes over the driving. The remote insulation-resistance measuring apparatus according to the present invention comprises: an access unit for accessing the secondary side of a high-voltage circuit breaker which is coupled to a backup high-voltage motor; a switching unit for measuring the conduction, voltage and insulation resistance of the backup high-voltage motor via the switching of an internal switching element; a measurement module for determining whether or not drive take-over has occurred by measuring the insulation resistance of the backup high-voltage motor which is coupled to the secondary side of the high-voltage circuit breaker via the switching unit; and a manager terminal which is coupled in serial communication with the measurement module, manages the overall action with respect to the operation of the measurement module, and records and analyses the measured insulation-resistance data.
