The invention discloses a switch cabinet for a power-generating car. The switch cabinet comprises a cabinet body, cables and a switch box, wherein the cable is used for connecting the power-generating car and a client; the switch box is arranged in the cabinet body; at least one group of four-phase single-core sockets are arranged on the switch box; the cables include a first client cable and at least one connection cable; single-phase plugs are arranged at two ends of the first client cable; a single-phase plug is arranged at one end of the connection cable, and a single-core socket is arranged at the other end of the connection cable. The switch cabinet has the advantages that the sockets are arranged on a copper bar of the switch cabinet; and the single-phase plugs and the four-phase single-core sockets are butted, so that the connecting speed of the cables is increased. The switch cabinet does not need to be dismantled; meanwhile, the client cable and the connection cable are arranged; and the cables can be lengthened according to the practical situation. Therefore, the switch cabinet is small in size, and convenient and flexible to install; and the space is reduced.
