Abstract
The invention relates to a silicon carbide rod test machine which is characterized by mainly comprising a protective circuit, a voltage stabilizing circuit, a timing circuit, a voltage regulator circuit and a test circuit. The silicon carbide rod test machine is simple in structure and reliable in work, and overcomes the shortcomings that only an avometer can be used for judging whether silicon carbide rods are aged or not at present, the silicon carbide rods which are good in performance and can still meet the normally-used requirements are frequently judged to be unavailable due to the fact that the test environments are different, and the errors are large, and high financial losses are caused in production.
