The utility model relates to a novel heat dissipation structure on a reactive power compensation device, which comprises a cabinet body provided with an electrical element, an air door arranged on the cabinet body, and an exhaust fan arranged on the upper end of the cabinet body, and is characterized in that a partition board is arranged in the cabinet body and divides the inner cavity of the cabinet body into two ventilation air ducts, and each air duct is communicated with the exhaust fan on the upper end of the cabinet body. The design adopts a mode of double heat dissipation air ducts connected in parallel so as to make the heat dissipater of two groups of antiparallel thyristors of each phase of circuit and corresponding resistance-capacitance absorbing, busbar and other electrical elements correspond to one air duct respectively, and the reactive power compensation device dissipates heat uniformly, so the utility model has simple structure, is economical and practical, occupies small area, has a reliabl
