  • Patent number: 12092700
    Abstract: An interactive test equipment for quality evaluation of resistance value test for electric leakage is disposed on a platform, and includes at least a control unit, a leaking electric current control module and an operating module. The leaking electric current control module includes at least a test set for quality evaluation to determine a resistance value for electric leakage. Each of the at least a test set has a circuit breaker and an electric leakage value display. The electric leakage value display of the each of the at least a test set can be used to display tripping circuit-breaking data of a corresponding circuit breaker. Test subjects can initiate the interactive test equipment and select answers through the operating module, and load questions and determine answers through the control unit.

  • Publication number: 20230104141
    Abstract: An interactive test equipment for quality evaluation of an insulative electric resistance value of an electric power cable at least includes a control unit, a test question type module and an operating module. The test question type module includes at least a test set. Each of the at least a test set includes at least an electric resistance value measuring part each of which has an electric voltage value display and an electric resistance value display to respectively display electric voltage values and electric resistance values of a corresponding cable. Besides, the operating module is used to initiate the interactive test equipment, to select answers, and the control unit is used to load question types and to make judgment on answers. Accordingly, test subjects are authenticated and evaluated for a judgment ability thereof in order for ensuring safety of a working environment.

  • Patent number: 11502462
    Abstract: An extension cord for polyphase voltage conversion includes a socket body, a conductive cable and a polyphase circuit disposed in the socket body. The socket body has a hollow housing, and a four-phase power connective head is disposed at an end of the housing in order to supply power to the extension cord. A breaker having safety switch function and at least two power sockets providing voltages with different phases are disposed in the housing. An end of the conductive cable is electrically connectable with a four-phase power source. The other end of the conductive cable has a four-phase power plug electrically connectable with the four-phase power connective head of the socket body. The polyphase circuit includes three phase conductors, a neutral conductor and a ground conductor. The conductors are used to electrically connect with the four-phase power connective head, the breaker and the respective at least two power sockets.
