Track traffic bidirectional converter testing device

The utility model relates to the technical field of converter testing equipment, in particular to a rail transit bidirectional converter testing device, and aims to solve the problems that after long-time work, the heat extraction efficiency is too low, and long-time stable work is difficult to guarantee. One side of the fixed connecting plate is provided with a self-adaptive partition plate, the self-adaptive partition plate is slidably connected to the inner wall of the upper end of the converter testing machine body, a heat discharge port is formed between the fixed connecting plate and the self-adaptive partition plate, heat is conducted to the mounting box body, the mercury liquid is heated to expand, the piston body is driven to push the ejector rod, the ejector rod pushes the self-adaptive partition plate, and the higher the temperature is, the longer the pushing distance is. Therefore, the larger the area of the heat discharge port is, the internal heat is communicated with the air through the heat di
