Distributed circuit measurement device used for low voltage power station

The utility model discloses a distributed circuit measurement device used for a low voltage power station. The device comprises a host, a CAN communication adapter card, a CAN bus, several data acquisition and control processing modules and several current transformers. The current transformers are connected with the data acquisition and control processing modules respectively and are arranged on each low voltage outgoing line loop of the low voltage power station in a distributed mode. The data acquisition and control processing modules access to the CAN bus respectively and then input data to the host through the CAN communication adapter card. Each data acquisition and control processing module comprises a current signal sampling circuit, a filter circuit, a signal conditioning circuit, an A/D conversion circuit and a single-chip microcomputer which are successively connected with each other. By using the distributed circuit measurement device used for the low voltage power station provided in the utility model, a current waveform before low voltage switch opening can be completely recorded, which is convenient for carrying out reason analysis of a low-voltage accident.
