The invention relates to the technical field of high-voltage switch cabinet maintenance equipment, in particular to a high-voltage switch cabinet handcart test device. The high-voltage switch cabinethandcart test device comprises a box body, a connection plug, a plurality of indicating lamps, a panel, a switch and a battery, the panel is installed in the box body, the plurality of indicating lamps are arranged and installed on the panel, a plurality of jacks are formed in the connection plug, the number and the arrangement of the jacks are matched with handcart binding posts, the indicating lamps are connected with jacks matched with binding posts for handcart loop detection through wires to form a detection loop, the connection plug is provided with a lock catch matched with a handcart,when the connection plug is inserted into the handcart binding posts, the lock catch is fixedly connected with the handcart in a clamped mode, and a jack connected with a binding post for a handcart low-voltage action test is connected with a low-voltage action characteristic instrument through a wire. The high-voltage switch cabinet maintenance equipment has the substantial effects that the jackmatched with the handcart binding posts are arranged on one connection plug so that all the binding posts can be connected with the test device only through one time of insertion, testing is rapid, and faulty line connection is not prone to occurrence.
