Zusammenfassung: | The utility model relates to a cooling fan device without fan blades for a dry-type transformer. The cooling fan device comprises the dry-type transformer, a cooling fan without fan blades, an insulation infrared temperature measurement sensing device and a control module. The cooling fan without fan blades is arranged nearby the dry-type transformer and directly faces a winding of the dry-type transformer, and the cooling fan without fan blades is used for conducting air blast cooling on the winding of the dry-type transformer. A temperature measurement probe of the insulation infrared temperature measurement sensing device is arranged nearby the winding of the dry-type transformer and directly faces the center of the winding of the dry-type transformer, and the temperature measurement probe is used for conducting non-contact temperature measurement on the winding of the dry-type transformer. The cooling fan without fan blades is connected to the control module through a control cable, and the insulation infrared temperature measurement sensing device is connected to the control module through an insulation optical fiber sensing data line. According to the cooling fan device without fan blades for the dry-type transformer, the infrared non-contact temperature measurement, sensing and control technology is used, forced air blast cooling automatic control is conducted on the dry-type transformer, the operation copper-iron loss of the dry-type transformer is effectively lowered, and the overload and short-circuit withstand ability can be effectively improved. |
