[0035] The operating module 50 is signally connected with the control unit 10. Further referring to FIG. 1 and FIG. 4, the operating module 50 includes at least an answer selecting switch set 51 corresponding to the at least a test set 21. Each of the at least an answer selecting switch set 51 has a normal switch 511 and an abnormal switch 512. The normal switch 511 and the abnormal switch 512 can be buttons. Five answer selecting switch sets 51 (i.e., 51A to 51E) corresponding to the five test sets 21 (i.e., 21A to 21E) are disposed in a main embodiment in accordance with the present invention. Each of the five answer selecting switch sets 51 is used for the test subjects to select answers via the normal switch 511 or the abnormal switch 512 based on voltage values between the different wiring connections of a corresponding transformer 211 displayed by the at least a voltage value display 214 of a corresponding one of the five test sets 21. According to some embodiments in accordance with the present invention, an indicating light set 52 is respectively disposed beside each of the at least an answer selecting switch set 51. The indicating light set 52 includes a normal light 521 and an abnormal light 522 respectively corresponding to the normal switch 511 and the abnormal switch 512 in order to display answers selected by the test subjects for facilitating confirmation from the test subjects and test supervisors.

Further according to some embodiments in accordance with the present invention, an action light 551 is respectively disposed beside the initiating switch 55. The action light 551 is used to display the interactive test equipment is electrified to be initiated, and tests taken by the test subjects can be started. In addition, the operating module 50 further includes a result judgment set 58. The result judgment set 58 includes a result switch 581 to initiate the interactive test equipment summarizing test results, a pass light 585 and a fail light 586. The result switch 581 can be a button. Furthermore, the operating module 50 includes a reset switch 59. The reset switch 59 can be a button. The reset switch 59 is used to reset or load a new question type through the control unit 10 in order to start a next test cycle. Further according to some embodiments in accordance with the present invention, a reset light 591 is respectively disposed beside the reset switch 59. The reset light 591 is used to display an initiating action of the interactive test equipment to reset and load a new question type in the interactive test equipment.

[0036] The control unit 10 is electrically connected with a power source 80 to supply power to the control unit 10, the test question type module 20, the operating module 50 and the transformer 211 of the interactive test equipment. According to some embodiments in accordance with the present invention, the control unit 10 is further signally connected with a voice module 90 in order to output reminding or alerting sounds or voices.

[0037] Accordingly, the interactive test equipment for determining whether a power transformer 211 is in a good or poor condition in accordance with the present invention is constituted to allow test subjects proceeding their judgment whether the transformer 211 is in any disconnection or breakdown conditions through the interactive test equipment.

[0038] Referring to FIGS. 5-6, actual test steps and processes for the interactive test equipment for quality evaluation of power transformers in accordance with the present invention are shown. In practice, a test subject presses the initiating switch 55 of the operating module 50 to power the interactive test equipment and to prepare the interactive test equipment being ready for the test subject so that the test subject can proceed through the interactive test equipment to determine whether wiring of the transformer 211 in the each of the at least a test set 21 of the test question type module 20 is in a good or poor condition. The control unit 10 accordingly electrically connects/disconnects wiring connections of the transformer 211 of the each of the at least a test set 21 based on a chosen question type, and powers the transformer 211. The interactive test equipment is then in an initiation status, and the voltage value display 214 and the resistance value display 215 respectively display corresponding electric voltage and resistance values of the transformer 211.

[0039] Subsequently, the test subject proceeds to select answers through the interactive test equipment. The test subject determines whether a corresponding transformer 211 is in a good or poor condition based on the displayed voltage values of the voltage value display 214 beside the transformer 211 of the test sets 21 (i.e., 21A to 21E), and presses the answer selecting switch sets 51 (i.e., 51A to 51E) of the operating module 50 corresponding to the test sets 21 (i.e., 21A to 21E) based on the determined answers, i.e., presses a corresponding normal switch 511 or abnormal switch 512 of the answer selecting switch sets 51 (i.e., 51A to 51E) based on the determined answers. Afterwards, the result switch 581 of the operating module 50 is pressed by the test subject. When the control unit 10 determines answers selected by the test subject on the answer selecting switch sets 51 (i.e., 51A to 51E) for all of the test sets 21 (i.e., 21A to 21E) are not completely correct, the voice module 90 outputs a fail voice, and the status indicating lamp 213 of every one of the test sets 21 (i.e., 21A to 21E) with a wrong answer on the transformer 211 thereof twinkles to display a corresponding normal or abnormal signal for the transformer 211. The test subject retakes the test and answers based on the above method and steps.

[0040] On the contrary, when the control unit 10 determines answers selected by the test subject on the answer selecting switch sets 51 (i.e., 51A to 51E) for all of the test sets 21 (i.e., 21A to 21E) are completely correct, the voice module 90 outputs a pass voice, and the reset switch 59 can be pressed so that the interactive test equipment enters a suspending status. After the control unit 10 loads a new question type for all of the test sets 21 (i.e., 21A to 21E) of the test question type module 20, the test for different test subjects to determine whether a corresponding transformer 211 is in a good or poor condition can be repeatedly proceeded.

[0041] Based on the above illustrations, the interactive test equipment for quality evaluation of power transformers in accordance with the present invention is disposed on a platform 100 to include the at least a control unit 10, the test question type module 20 and the operating module 50, and the at least a control unit 10, the test question type module 20 and the operating module 50 are signally connected. The test question type module 20 includes at least a test set 21, and each of the at least a test set 21 has the transformer 211, the at least a voltage value display 214 and the at least a resistance value display 215. Based on the above design, the at least a voltage value display 214 and the at least a resistance value display 215 of the each of the five test sets 21 (i.e., 21A to 21E) can display a measured voltage value and a measured resistance value of a corresponding transformer 211. Test subjects can initiate the interactive test equipment and select answers through the operating module 50, and load questions and determine answers through the control unit 10. As a result, the interactive test equipment is used to allow test subjects determining whether a transformer is in a good or poor condition through an interactive test method, and then to authenticate and evaluate a judgment ability of the test subjects in order to ensure safety of a working environment.

[0042] Accordingly, it can be understood that the present invention is an extremely creative invention. In addition to effectively solving problems faced by the ordinarily skilled in the art, the present invention is also configured to greatly improve efficacy. Besides, no identical or similar product in the same technical field can be found to be invented or in public use, and the present invention has enhanced advantages simultaneously. Therefore, the present invention meets requirements of “novelty” and “non-obviousness” as stipulated for utility patent applications in the patent law, and a patent application for the present invention is filed in accordance with the patent law.
