The invention relates to a high voltage DC breaker valve tower structure. The high voltage DC breaker valve tower structure comprises multiple breaker power assemblies which are sequentially connected in series and are distributed from up to down with intervals layer by layer, an inter-layer supporting structure is arranged between any two adjacent breaker power assemblies to form a valve tower body, the valve tower body is supported on a bottom portion supporting insulator structure, the valve tower structure further comprises a lightning arrester assembly correspondingly arranged at a side of the valve tower body, and the valve tower structure further comprises a suspension device used for suspending the valve tower body under a corresponding suspension beam. The multiple breaker power assemblies are distributed from up to down with intervals layer by layer and are relatively tight in space, so the horizontal land occupation area is relatively small, moreover, the valve tower body employs a dual-reinforcement measure capable of realizing both the top portion suspension effect and the bottom portion supporting effect, the valve tower antivibration performance can be effectively improved, structural strength requirements for the bottom portion supporting insulator structure are reduced, and more breaker power assemblies can be laminated in the vertical direction.
