<p>A multi-model test device for an inverter by the present invention comprises: a jig; a track installed on the jig; multiple carriers installed on the track to be able to move; multiple connection rods which are extended and installed from the carriers; an actuator installed on the jig to move the connection rods through the carriers; an inverter lifter which is installed to face the connector rods and moves the inverter to connect the inverter to the connection rods; an arrangement conversion unit which is connected with the connection rods on a circuit and converts terminal arrangement of the connection rods; and multiple test terminals connected with the arrangement conversion unit on the circuit. The multi-model test device comprises multiple terminal ports of different number by the type in a row according to the different distance by the type. When the inverter which connects the terminal ports with inverter terminals according to the different arrangement by the type is tested, the connection rods of the required number are moved to a necessary position to be matched with the number and distance of the terminal ports and the terminal arrangement of the connection rods are changed to be matched with the terminal arrangement of the inverter to be tested. Eventually, the test terminals are connected to the inverter terminals to be matched. Therefore, various types of inverters can be tested with a single test device and costs and resources inputted to the production of a test device can be saved compared to existing one which tests an exclusive device by many types. Moreover, a testing time required for the change, installation, and mounting of the test device can be reduced and a space required for the storage and movement of the test device can be reduced. Therefore, costs and resources such as capital investment costs, operating costs, etc., can be saved.</p> |
