Power distribution box capable of being assembled and used for three-phase four-wire meter box and single-phase meter box

Abstract

The utility model discloses a power distribution box capable of being assembled and used for a three-phase four-wire meter box and a single-phase meter box. The power distribution box comprises the three-phase four-wire meter box, a power box and the single-phase meter box which are assembled and connected. A first dovetail tenon is arranged on one side, connected with the three-phase four-wire meter box, of the power box; a first dovetail mortise is arranged on one side, connected with the single-phase meter box, of the power box; a second dovetail mortise corresponding to the first dovetail tenon is arranged on one side, connected with the power box, of the three-phase four-wire meter box; the side, connected with the power box, of the single-phase meter box is provided with a third dovetail tenon corresponding to the first dovetail mortise. The three-phase four-wire meter box and the single-phase meter box are arranged on the two sides of the power box respectively, the three-phase four-wire meter box and the single-phase meter box share the power box, lines of a plurality of power supply points are reduced, meanwhile, the three-phase four-wire meter box, the power box and the single-phase meter box are arranged to be of a detachable tenon-and-mortise connection structure, and when a single component part is damaged, the three-phase four-wire meter box and the single-phase meter box can be replaced by the detachable tenon-and-mortise connection structure. And disassembly and maintenance of a single component can be realized, and the maintenance cost is reduced.
