1. A parallel assembly of rectifier modules, comprising:
a plurality of rectifier modules connected in parallel;
a switch for switching-in and switching-out of the rectifier modules;
an assembly frame, being provided therein with a switch accommodating space and a rectifier module accommodating space which are sequentially arranged along the height direction;
a DC bus bar, being arranged at a top of the assembly frame and located outside the assembly frame; wherein the DC bus bar comprises a DC bus bar positive pole and a DC bus bar negative pole;
a plurality of groups of connectors, being fixed at one end close to a back side of the assembly frame and located in the rectifier module accommodating space; each group of connectors comprising an input connector and an output connector;
an AC copper bar, being fixed at one end close to a front side of the assembly frame and located in the switch accommodating space; wherein the AC copper bar comprises an AC input copper bar and an AC output copper bar;
an extended copper bar, being fixed at one end close to the back side of the assembly frame and located in the switch accommodating space;
wherein the AC input copper bar and the AC output copper bar are electrically connected with the switch, the extended copper bar is electrically connected with the AC output copper bar, and the extended copper bar is electrically connected with the input connector; the output connector is electrically connected with the DC bus bar;
the outer surface of the rectifier modules is provided with a pair of plug interfaces which are matched with a group of the connectors so that the rectifier modules installed in the rectifier module accommodating space are electrically connected with the input connector and the output connector through the plug interfaces.
