| Zusammenfassung: | The utility model discloses a direct-current insulation monitoring device, which comprises a remote control (RC) clamping grounded circuit 1, a positive and negative power supply voltage monitoring circuit 2, an inspection and comparison sound-light alarm circuit 3 and a power supply module 4. Since the RC clamping grounded circuit 1 and the positive and negative power supply voltage monitoring circuit 2 form a direct-current insulation inspection system, when the insulation of a direct-current anode or a direct-current cathode is faulted, the positive and negative power supply voltage monitoring circuit 2 can convert voltage analog quantities into digital quantities which are sent to the inspection and comparison sound-light alarm circuit 3 and then a sound-light alarm is given out by the inspection and comparison sound-light alarm circuit 3. The direct-current insulation monitoring device has the advantages that the structure is reasonable, the device is convenient to use, a direct-current insulation fault |
