High-voltage isolating switches are used in the electric industry in common. But in the railway industry, it is one of the key components of locomotives. It's function of isolating 25KV electricity running in the special net of the railway, preventing danger of the high-voltage for the locomotive crew life and protecting the locomotive performance. At present, the high-voltage isolating switch still adopts manual detection and maintenance. There are some shortcomings such as inaccurate measurement data, low precision, and poor stability. This paper has given a bench plan which structures are designed in detail. The control principle, precision calculation, and stability prin-ciple of the bench are briefly explained. According to the plan, the test bench built can meet the requirements of the industry standard. At the same time, the test bench has some structure automatic functions such as testing and printing, and the equipment that has been put into production is in good condition. It is served in the plant of advanced locomotive mainte-nance and has good performance.
