The invention belongs to the field of intelligent components of power transformers, and particularly relates to an intelligent universal hardware platform for the power transformers. The intelligent universal hardware platform comprises a case, a power module, a switching value input module, a switching value output module, a direct current value acquisition module, an alternating current value acquisition module, a temperature value acquisition module, a master control module and a high-tension bushing monitoring module, wherein the power module, the switching input module, the switching output module, the direct current value acquisition module, the alternating current value acquisition module, the temperature value acquisition module, the master control module and the high-tension bushing monitoring module are arranged in the case. The intelligent universal hardware platform for the power transformers has the functions of switching value input acquisition, switching value output control, temperature data acquisition, alternating current value acquisition, direct current value acquisition, high-tension bushing condition monitoring, comprehensive analysis and diagnosis and the like, and all the modules are placed in the standard case which is 19-inch 4U high. In practical application, the number of the modules can be freely increased or decreased according to site conditions and requirements of the matched power transformers, so that space and hardware resources are fully utilized. The intelligent universal hardware platform for the power transformers is applicable to intelligentization of the power transformers at all voltage levels.
