Embodiment Construction

[0015] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] like figure 1 As shown, the heat dissipation fan for the main transformer room of the present invention includes an air outlet 1, an air guide barrel 2, a fan 7, and a fixed plate 8, and the fan 7 is fixed in the cavity in the air guide barrel 2 by the fixed plate 8, so The wind guide bucket 2 is fixedly connected with the air outlet 1 , and the outer ring of the wind guide bucket 2 is provided with a ring-shaped rib 4 , the rib 4 is made of metal, and the rib 4 is fixedly connected with the wind guide bucket 2 . After the ring-shaped convex rib 4 is provided, it can effectively prevent the air guide barrel 2 from loosening and falling off from the opening on the wall. It solves the problem that the air guide barrel is not tightly connected with the opening, which may easily cause looseness and cause safety accidents. Preferably, a lou...

Abstract

The invention discloses a cooling fan for a main transformer room. The cooling fan comprises an air outlet, an air guide barrel, an air fan and a fixing plate; the air fan is fixed in a cavity in the air guide barrel through the fixing plate, the air guide barrel is fixedly connected with the air outlet, and an annular convex edge is arranged on the outer ring of the air guide barrel, and is fixedly connected with the air guide barrel; the problems that connection of the air guide barrel and an opening is not tight, loosening is likely to happen, and safety accidents are caused are thoroughly solved, meanwhile, the cooling fan is provided with a controller and a temperature sensor, and it is ensured that when the temperature of a transformer or the main transformer room exceeds the threshold value, a main controller starts the air fan for rotation, and the transformer or the main transformer room is cooled.

Description

technical field [0001] The invention relates to an exhaust device, in particular to a cooling fan for a main transformer room. Background technique [0002] Fans are widely used in ventilation, dust removal and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induction of boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances ; Drying and selection of grain; Wind tunnel wind source and inflation and propulsion of hovercraft, etc. But the blower fan of prior art generally all is to directly contact the opening on the wall with the air guide bucket, and such design is easy to cause loosening at the joint, and after a long time it will cause the air guide bucket to fall from the wall, causing a safety accident. Especially in the main transformer room of the substation, if the fan used for ventilation and heat dissipation is loose and falls off, it may endanger the safe ...
