The utility model relates to an aging test device of a movable vacuum breaker, which is applicable to an aging test of a switching capacitance vacuum breaker at a high-voltage operating field and in a testing laboratory. The aging test device comprises a primary part YCB and a measurement and control device CKZ; the primary part YCB consists of a high voltage circuit and a large current circuit; and the aging test device is characterized by also comprising a motor vehicle which is loaded with the primary part YCB and a measurement and control device CKZ. The utility model has the advantages that the aging test device can be transported to the high voltage operating field to carry out aging test to the switching capacitance vacuum breaker; after the vacuum breaker is installed on the field, the equipment is in real operating state, thus further inspecting the influence of the installation to the reignition of the vacuum breaker and having more practical significance for switching capacitor bank of the vacuum breaker in the real operating aspect of the field.
