Abstract

The invention relates to a power supply system and a modular distribution device thereof. The modular distribution device comprises a three-phase main input circuit and a main input wiring terminal for providing AC power source access for the three-phase main input circuit. The distribution device also comprises a cascade terminal connected with the main input wiring terminal, and the cascade terminal is used for providing AC power source access for a three-phase main input circuit of an adjacent distribution device. When the technical scheme of the invention is implemented, the cascade terminals of two adjacent distribution devices are connected together, and the cascade terminal of each distribution device is connected with the main input wiring terminal of the distribution device, therefore, an AC power source can simultaneously supply power to the distribution devices of the two cascade terminals when the AC power source is accessed to the main input wiring terminal of any distribution device, and the quantity of output branches of the distribution device is increased.

Description

technical field [0001] The present invention relates to power electronics technology, more specifically, to a power supply system and a modular power distribution device thereof. Background technique [0002] The power distribution unit of the AC power supply is used to realize the metering and control distribution of electric energy. Existing power distribution devices usually consist of a main circuit input terminal, a branch circuit switch, a branch circuit output terminal, a branch circuit current detection element, a monitoring unit and an auxiliary power supply. Most of its main road input does not take into account the cascading requirements of the power distribution device, which limits the expansion of the number of output branches. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a modularized power distribution device capable of overcoming the above-mentioned defects in view of the defect that the expa...
