Abstract

The invention aims at providing a switching type phase sequence switching combined conjunction box, and relates to the power field. The switching type phase sequence switching combined conjunction boxcomprises a conjunction box body, a box cover, a wiring board arranged in the conjunction box body and provided with three voltage and current wiring blocks, and a phase sequence switching switch electrically connected to the first and third voltage and current wiring blocks. Each of the first and third voltage and current wiring blocks comprises an electrical connection assembly and a switchingassembly; the electrical connection assembly comprises a voltage electrical connection column and middle, left and right current electrical connection columns; the switching assembly comprises a voltage switching terminal and left and right current switching terminals; and the middle electrical connection column is electrically connected with the right/left current electrical connection column. When being used for phase sequence adjustment, the switching type phase sequence switching combined conjunction box does not influence power utilization of users, and is higher in phase switching efficiency and higher in safety level.
