Abstract

The invention discloses a power supply unit and a bus power supply module adopting the power supply unit. The power supply unit comprises an upper cover, a power supply body shell, a three-phase switch, a wiring terminal, an indicating lamp, a hook, a power supply adapter, a rectification power supply board, a three-phase plug reed, a low-voltage power supply anode reed and a low-voltage power supply cathode reed. The three-phase switch is connected with the three-phase live wire plug reed so as to obtain an AC 380V power supply from a power supply bus, the AC 380V power supply is rectified into a direct current through the rectification module, and then the direct current is reduced into a DC 24V voltage to be supplied to the low-voltage power supply positive reed and the low-voltage power supply negative reed. The bus power supply module comprises two groups of power supply units arranged side by side, two groups of relay units arranged side by side, two groups of bus bodies arrangedside by side and two groups of guard board groups arranged side by side, two adjacent power supply units are connected through a power supply wire, high-voltage direct-current parts of the two powersupply units jointly serve as double-circuit input of a power supply, power supply is stable, and segmented output can be achieved.

Description

technical field [0001] The invention relates to electric power supply technology, in particular to a power supply unit and a bus power supply module using the power supply unit. Background technique [0002] The terminal bus bar is usually a terminal power distribution device composed of copper conductors and aluminum alloy shells. Through the matching plug-in boxes and other devices, it can realize the function of supplying power to specific equipment. However, the existing terminal busbar power supply mode is single, and it is impossible to realize segmental power supply, which is limited in popularization and application. Contents of the invention [0003] In order to overcome the shortcomings of the prior art, the object of the present invention is to provide a power supply unit and a bus power supply module using the power supply unit, which can solve the above problems. [0004] The object of the present invention adopts following technical scheme to realize: [00...
