The utility model provides a low
power consumption ADMU
system, comprising a primary and secondary fusion pole-mounted switch and a power distribution terminal, the primary and secondary fusion pole-mounted switch is provided with a digital unit, an operating mechanism, a
voltage sensor and a
current sensor, and the power distribution terminal is provided with a CPU module, a power
supply management module and a power supply module. The digital unit is used for collecting analog current and
voltage signals and switching value signals and sending the analog current and
voltage signals and the switching value signals to the CPU module through an RS485
bus. The
digitization unit comprises a
digitization ADMU module, a switching value acquisition module, an AD module and a power supply isolation unit, the
digitization ADMU module is connected with the operation mechanism through the switching value acquisition module, and the digitization ADMU module is connected with the
voltage sensor and the
current sensor through the AD module. According to the utility model, the problem that a large number of cables are needed by traditional electromagnetic signals can be solved, so that the purposes of saving cost, reducing wiring
failure rate and improving operation reliability of the controller are achieved.
