Detection Method of Distribution Transformer Based on Intelligent Switching Line Switch

Automatic and intelligent detection of distribution transformer is an important condition to ensure distribution network zero defect operation. The traditional distribution transformer quality detection system has low integration and automation, and a single function mode, which cannot meet the intelligent detection under different test scenarios. This paper introduces the basic principle of intelligent switching line, and develop a special automatic switching device according to the actual detection process. On this basis, an intelligent switching line switching device is designed according to the test requirements of distribution transformer. Finally, the actual test results show that the proposed distribution transformer detection method based on intelligent switching line switch can significantly reduce the detection time and improve the detection efficiency of distribution transformer.
