Description
Technical Field
The utility model relates to an electric power system's transformer overhauls technical field, especially relates to a transformer cooling fan.
Background
Transformers are one of the most important devices in power systems. During transformer operation, heat generated by losses in the windings and core must be dissipated in time to avoid insulation damage due to overheating. For a small-capacity transformer, the ratio of the external surface area to the volume of the transformer is relatively large, and heat can be dissipated by radiation and natural convection in a self-cooling mode. However, as the social development speed is faster and faster, the transformer is more and more heavily loaded, and the generated heat can damage the transformer if the generated heat cannot be dissipated in time.

In order to achieve the above purpose, the technical scheme of the utility model is that: the utility model provides a transformer cooling fan, includes fan casing, fan cooling tube, flabellum, rotating electrical machines, honeycomb duct, storage water tank and refrigerator, the coupling joint flabellum is passed through to the one end of rotating electrical machines's output shaft, the flabellum is installed in the fan casing, the bottom at fan casing is installed to the fan cooling tube, the fan cooling tube links to each other with the honeycomb duct, the honeycomb duct links to each other with storage water tank, refrigerator, the cooling water that the refrigerator preparation obtained flows through fan cooling tube, honeycomb duct, storage water tank, refrigerator circulation.
Further, the fan cooling pipe is in a spiral disc-shaped structure.
Further, the fan blades have 4-8 blades.
Furthermore, a heat-insulating layer is arranged outside the flow guide pipe.
Furthermore, an upper cover which can be opened and closed is arranged at the top of the water storage tank, and a heat insulation layer is arranged on the outer surface of the upper cover.
Further, a heat insulation layer is arranged outside the water storage tank.
The utility model adopts the above technical scheme's beneficial effect is: the utility model relates to a transformer cooling fan through the refrigerator with the water-chilling, the leading-in fan cooling tube of cooling water circulation drives the peripheral air current cooling of fan, improves transformer cooling efficiency, and in the cooling water can not flow into the transformer, can effectively avoid the transformer that the too big transformer that leads to of humidity in the transformer is ageing, and the practicality is strong.
The utility model relates to a transformer cooling fan, the fan cooling pipe is spiral disk structure, can increase the contact area of fan cooling pipe and fan peripheral air current, the cooling effect is good; the heat preservation layers are arranged outside the flow guide pipe and the water storage tank, so that the heat preservation effect is good, the capacity loss is less, and the energy conservation and the environmental protection are realized; the top of the water storage tank is provided with an upper cover, so that water can be conveniently added.
