Abstract
The utility model relates to a novel low-voltage leading-out terminal box for an oil-immersed rectifier transformer for variable frequency speed regulation. The low-voltage leading-out terminal box comprises multiple groups of low-voltage leading-out terminal box bodies installed on a rectifier transformer body, each group of the low-voltage leading-out terminal box bodies comprises a plurality of leading-out terminals, and each low-voltage leading-out box body, a left adjacent low-voltage leading-out box body and a right adjacent low-voltage leading-out box body are not on the same horizontal line. The novel low-voltage leading-out terminal box resolves the problems that the low-voltage leading-out terminals of the oil-immersed rectifier transformer for the variable frequency speed regulation are multiple, cannot be arranged on the top of an oil tank and can only be arranged on the side wall of the oil tank, but space of the side wall is limited, and the leading-out terminals cannot be well arranged on the space of the side wall; the low-voltage leading-out terminal box bodies are adopted to be safely provided with the leading-out terminals, and meanwhile the terminal box is provided with sealing adhesive strips, so the problem of oil leakage due to side wall placement can be effectively resolved.
