Claim:
1. A heat-dissipating system for high-power cabinet, comprising: a cabinet, which has a cuboidal shape; at least one main air duct with a first opening and a second opening, which is formed in the cabinet, the at least one main of duct comprising independent air ducts, and a first heat-generating assembly; a second heat-generating assembly and at least one first fan, which are mounted in of the at least one main air duct, the first fan is located between the first heat-generating assembly and the second heat-generating assembly; and an outlet of the first fan faces towards the first heat-generating assembly, airflow in the main air duct flows from the first opening to the second heat-generating assembly, an inlet of the first fan, the outlet of the first fan, and the first heat-generating assembly in sequence, and finally is discharged out of the cabinet from the second opening of the main air duct of the cabinet; wherein the first heat-generating assembly is an IGBT power module, the second heat-generating assembly is a reactor, and the first heat-generating assembly and the second heat-generating assembly are both electronic assemblies used in the Static Var Compensation system, wherein a heat amount from the first heat-generating assembly is larger than a heat amount from by the second heat-generating assembly; the first heat-generating assembly and the second heat-generating assembly are both electronic assemblies used in the power system.
