System debug method of movable type direct current ice melting apparatus based on gate turn-off (GTO) device

The invention relates to a system debug method of a movable type direct current ice melting apparatus based on a gate turn-off (GTO) device. The method comprises the following steps: (1) a direct current ice melting apparatus carries out a low voltage signal test without an ice melting line; (2) the direct current ice melting apparatus carries out a zero load test without the ice melting line; (3) the direct current ice melting apparatus carries out an undercurrent test without the ice melting line; (4) the direct current ice melting apparatus carries out heavy current test and ice melting load line temperature rise test. Thereby, the invention can guarantee that the system debug can examine the performance of the apparatus. The system debug method provided in the invention is reliable and feasible.
