The invention relates to a vacuum circuit breaker transfer vehicle with adjustable width and height. The vacuum circuit breaker transfer vehicle comprises a body provided with a mobile device at the bottom and a hydraulic lifting assembly, wherein the body is movably connected with a brake assembly and is provided with at least one set of positioning assemblies and guide assemblies with an adjustable gap, and a locking assembly for locking a vacuum circuit breaker on the body is arranged on the guide assemblies. The vacuum circuit breaker transfer vehicle has the advantages that the reliable locking between the body and the vacuum circuit breaker as well as between the body and a cabinet body is guaranteed and the center of gravity of the body is effectively lowered as the cabinet body provided with the vacuum circuit breaker is fixedly arranged on the body through the positioning assemblies and the vacuum circuit breaker is fixedly locked on the body through the locking assembly, as the gap between the positioning assemblies is adjustable and the height adjustment is performed by the control of the hydraulic lifting assembly, the body can be adaptive to different models effectively, the universality is strong, the work efficiency is greatly improved, and the use effect is good.
