Actual fault cases have shown that arc discharges occurring in the high potential internal area can generate huge pressure within the oil tank, which may lead to the rupture, explosion and fire of the oil tank. This paper proposes to add aluminum honeycomb panels on the oil side wall of the transformer tank to solve this problem. By deforming to buffer the pressure, it can reduce the damage to the tank wall. Preliminary tests were conducted on the arc discharge of energy absorption materials to evaluate the feasibility of this method. Subsequently, three specific structural design schemes for the transformer tank wall were proposed. Considering the computational efficiency, a 1/16 equivalent proportion ultra-high voltage (UHV) converter transformer model was established. Using the finite element simulation method, the pressure attenuation, stress distribution characteristics and structural failure risks of different design schemes were comprehensively evaluated, which verified the effectiveness of this structure. This also provides a new direction for the research on transformer explosion prevention in response to high-energy arc faults.
