The utility model relates to a power equipment detects technical field, is a transformer portable shell, and it includes casing and base, the casing is including being U -shaped and relative first casing and the second casing of opening, and fixed mounting has first casing and the second casing that the ability make -up is connected on the base. The internal and external network physical isolation data exchange device is reasonable and compact in structure, high durability and convenient use, slide in the base in the follow base left and right sides respectively at experiment platform first casing of dismouting in -process and second casing, be connected sealed transformer main body with the cooperation of transformer main body caping, can quick first casing of separation and second casing in the time of need demolising the casing, pull down first casing and second casing from the base, thereby effectively solved when differentiating the winding trouble, the problem that needs frequent dismouting transformer, greatly shorten the time of correlative study, the efficiency of research is improved, can popularize and apply.
