Beschreibung
Zusammenfassung:	The invention discloses a cooling system of a feed pump frequency converter and the feed pump frequency converter, the cooling system of the feed pump frequency converter comprises a pure water cooling subsystem, an air water cooling subsystem and a closed cooling water supply subsystem, the pure water cooling subsystem is used for cooling a power unit of the frequency converter, and the air water cooling subsystem is used for cooling the power unit of the frequency converter. The pure water cooling subsystem is used for cooling water in the frequency converter, the air-water cooling subsystem is used for cooling a transformer of the frequency converter, and the closed cooling water supply subsystem is used for cooling water in the pure water cooling subsystem and cooling air in the air-water cooling subsystem, so that the pure water cooling subsystem and the air-water cooling subsystem can continuously cool the frequency converter. Therefore, the cooling system provided by the embodiment of the invention can
