The invention discloses a power system switch handcart examination auxiliary apparatus comprising a case body equipped with a hollow chamber therein. Conductive pipe holes in cooperation with conductive pins on a connector are disposed on the case body and are arranged corresponding to the conductive pins uniformly distributed on the connector. A rectification circuit and an outwardly-extending AC power line of the rectification circuit are installed in the case body. The conductive pipe holes at least comprise a power energy storage positive pipe hole, a power energy storage negative pipe hole, a conductive self-locked positive pipe hole, a conductive self-locked negative pipe hole, a power-on pipe hole, a power-off pipe hole, and a common pipe hole. The power energy storage positive pipe hole and the conductive self-locked positive pipe hole are electrically connected with the positive output end of the rectification circuit. The power energy storage negative pipe hole and the conductive self-locked negative pipe hole are electrically connected with the negative output end of the rectification circuit. The power-on pipe hole, the power-off pipe hole, and the common pipe hole are connected with pipe hole power lines. In a switch handcart test, the power system switch handcart examination auxiliary apparatus may easily perform test wire connection, is not liable to errors, is high in reliability and easy to operate, and saves time and labor.
