The invention provides a current-transformer cabinet body for a light-rail vehicle. The cabinet body includes a bottom plate, a sidewall plate arranged fixedly on the bottom plate and at least two lifting lugs. The bottom plate and the sidewall plate define an accommodating cavity used for accommodating a current transformer device. The bottom plate includes installation transition parts formed at the edges of the top faces of the bottom plate. Each installation transition part is provided with at least two connection through holes. The tail ends of the lifting lugs pass through the connection through holes and extend into the accommodating cavity. The head ends of the lifting lugs are located outside the accommodating cavity and the lifting lugs are also welded and fixed respectively with surfaces of the installation transition parts, facing inwards and surfaces of the installation transition parts, facing outwards. The current-transformer cabinet body for the light-rail vehicle improves the connection strength between the lifting lugs and the bottom plate significantly and capable of satisfying a vibration state in an operation process of the light-rail vehicle; and moreover, the welding process difficulty is also reduced so that the fabrication procedure of the current-transformer cabinet body is better.
