The invention discloses a high-voltage power distribution box of an electric automobile. The high-voltage power distribution box of the electric automobile comprises a box body, a box cover adaptive to the box body and a detection line, wherein a battery input socket and more than two high-voltage line sockets are arranged on the box body, the detection line comprises a travel switch and more than two socket connector interlocking circuits serially connected with the travel switch, and the travel switch is arranged between the box body and the box cover and is used for detecting whether the box is opened or not; each socket connector interlocking circuit comprises a first conducting wire arranged at the position of the high-voltage line socket and a second conducting wire arranged in a high-voltage line plug, the first conducting wire comprises two conducting wires, one end of the second conducting wire is coupled to one conducting wire of the first conducting wire, and the other end of the second conducting wire is coupled to the other conducting wire of the first conducting wire. The high-voltage power distribution box of the electric automobile disclosed by the invention can detect whether the power distribution box is opened or not and whether a high-voltage line falls off or not, and the leakage protection of the high-voltage power distribution box and the electric automobile is greatly improved.
