The invention provides a transformer based on multiple protection devices. The transformer comprises a transformer body, rubber cushion corners, an adjustable fixing frame structure, a left support rod, a right support rod, a positioning buffer damping frame structure, a transverse rod, a guide ring, a sunshade and rain shield, a solar photovoltaic panel, a photovoltaic controller, an auxiliary heat dissipation frame structure and a power distribution frame structure. The rubber cushion corners are adhered at the lower four corners of the transformer body. The adjustable fixing frame structureis arranged on the lower side of the transformer body. The buffer spring is arranged on the lower side of the L-shaped frame and sleeves the outer side of the longitudinal positioning rod so that theL-shaped frame can be buffered in use and the shock absorption effect on the transformer body can be realized during earthquake; and the transverse cushion frame is welded at the lower part of the lower fixing frame so that the climbing ladder can be conveniently stored in use and the climbing ladder can be prevented from being placed on the distribution box to affect the opening of the protection door.
