Enterprise power grid optimizing configuration method

Abstract

The invention discloses an enterprise power grid optimizing configuration method and relates to the field of electrical engineering. The enterprise power grid optimizing configuration method includes the four steps of power input, current metering, power supply for power and power supply for illumination. A three-phase high voltage wire is led to a transformer room through a protective pipeline, and the three-phase high voltage wire passes through a three-wire shunt connector first, then passes through a converter and finally is led to a power supply power measurement transformer. Because the power of an input power supply can be measured, power distribution can be optimized, resources are saved, energy consumption is reduced, enterprise benefits are improved, power supply for power and power supply for illumination are output separately, independence of a circuit is improved, the probability of power failure can be lowered, and electrical safety of an enterprise is improved.
