The modular rack distribution box is designed to adapt to the micro machine room and installed in the standard cabinet. The module adopts standard rack installation mode, and the minimum installation height is 3U. The shell is made of national standard 1.5 ~ 2mm high-quality cold plate or aluminum zinc coated plate, made of a full set of CNC equipment, pickled and Phosphated, and then high-voltage electrostatic spraying of high-strength phenolic resin. High processing precision, good anti-corrosion performance and firm structure.

The module full-function intelligent monitoring system adopts high-precision data acquisition equipment, which can accurately measure various parameters of the distribution system, including incoming voltage, current, apparent power, active power, reactive power, active electric energy, reactive electric energy, power frequency, power factor, 3 ~ 31 currents per phase, voltage harmonics, incoming switch status, lightning arrester status, etc; And the voltage, current, load percentage, active power, reactive power, active electric energy (true RMS), reactive electric energy (true RMS), switching state, shunt 3 ~ 31 current and voltage harmonics of the branch circuit. The number of shunt 3-pole switches, single pole switches and transformer ratio can be set arbitrarily, and the fault alarm of shunt switch can be shielded arbitrarily. Comprehensive fault early warning and alarm function can realize overvoltage, undervoltage, overcurrent, frequency out of limit of main incoming line and branch line, disconnection or fault alarm of main incoming line switch, lightning arrester and branch switch. The monitoring system has the selection function of single channel single test and dual channel double test, so that the dual power supply under 2n power supply mode can be centrally monitored in one system. The monitoring system adopts 32-bit arm real industrial microprocessor, which has faster speed, stronger function and higher integration
