Zusammenfassung: | The utility model provides an electronic type multiuser intelligent electric meter, and belongs to the field of electric energy meters. The electronic type multiuser intelligent electric meter comprises inlet line ends, outlet line ends, buses, feed lines and relays. A control circuit is arranged. The control circuit comprises a single-chip microcomputer, a metering chip and logic chips. The three phases of the inlet line ends are respectively connected with one side of different buses. One end of each feed line is connected with the buses, and the other end of each feed line is connected with the outlet line ends via the relays. The metering chip is connected with the three phases of the inlet line ends via voltage transformers. Current transformers are arranged and sleeve the feed lines. The output ends of the current transformers are connected with the metering chip via the logic chips. The metering chip is connected with the single-chip microcomputer. A relay control chip is arranged. The control ends of the relays are connected with the single-chip microcomputer via the relay control chip. The space occupation is small and viewing is convenient. |
