The application discloses an on-load tap changer action simulation test device and a test method, wherein the device includes: a base for providing support; a drive unit arranged on the base; a number of contact units, each of which includes multiple A contact group of three moving contacts, each contact unit is connected with the driving unit, and is evenly distributed around the circumference of the driving unit; when the driving unit is working, the driving unit drives the moving contacts of the contact group of the contact unit radial reciprocating movement; several test units, each test unit is provided with a force sensor for testing the contact pressure of the contact group of the contact unit to obtain test data; the acquisition device is used for collecting test data of the test unit, and The test data is transmitted to the host computer for processing and recording. Through the above method, the application can realize the simulation of the operation process of the on-load tap changer and obtain the test data in the operation process in real time; it has the advantages of reliable principle, simple and compact structure.
Description
technical field [0001] The application relates to the technical field of scientific instruments and transformer on-load tap-changers, and in particular, to an on-load tap-changer action simulation test device and a test method. Background technique [0002] Whether the contact of the on-load tap-changer is stable or not, and whether the switching sequence is correct or not are the two most important intuitive manifestations to measure whether the on-load tap-changer is working normally. force (contact pressure), contact wear, and bounce vibration during opening and closing. At present, there is no test device that simulates the action process of the on-load tap-changer and obtains the changes of key parameters (such as contact pressure, contact resistance, vibration response, etc.) during the action process in real time. There are still some limitations in providing a basis for defect detection and fault warning. SUMMARY OF THE INVENTION [0003] The present application ...
