Special heat radiation apparatus for local heating points of electrical equipment

Abstract

The invention discloses a special heat radiation apparatus for local heating points of electrical equipment, and relates to the technical field of operation and maintenance of factory power supply anddistribution system. The special heat radiation apparatus includes a motor, fan blades, an air inlet, a cylindrical glass fibre air hose, a tapered glass fibre air collection tube, an air port adjusting bolt, an insulated fixing support and a guard net, wherein the fan blades are fixedly arranged on an output shaft of the motor; the motor is fixed at the middle of the cylindrical glass fibre airhose; the cylindrical glass fibre air hose is movably arranged on the insulated fixing support; and the guard net is arranged at the air outlet. The special heat radiation apparatus for local heatingpoints of electrical equipment adopts well-insulated materials to replace conductive carbon steel materials used in a traditional fan, has good insulation during movement and use so as to ensure equipment and personal safety, and has a simple wind collecting structure, thus effectively improving the heat dissipation performance of the fan, eliminating the hidden danger of electrical equipment heating, and slowing down the insulation aging speed of equipment.

Description

technical field [0001] The invention relates to the technical field of operation and maintenance of power supply and distribution systems in factories, in particular to a heat dissipation device for local heating points of electrical equipment. Background technique [0002] In the operation of large-scale factory power supply and distribution systems, due to irregular installation, overload operation, poor contact, surface oxidation, poor ventilation, etc., the contact parts of the electrical equipment often experience severe local heating of the electrical equipment, with local points as high as Above 120°C, especially for high-current equipment in high-temperature seasons, if forced cooling is not adopted, the insulating materials near the heating point will accelerate aging, which will cause system shutdown if it is mild, and equipment and personal injury accidents if severe. [0003] At present, the commonly used forced heat dissipation measure is to place a fan at the h...

Problems solved by technology

[0002] In the operation of large-scale factory power supply and distribution systems, due to irregular installation, overload operation, poor contact, surface oxidation, poor ventilation, etc., the contact parts of the electrical equipment often experience severe local heating of the electrical equipment, with local points as high as Above 120°C, especially for high-current equipment in high-temperature seasons, if forced heat dissipation is not adopted, the insulation material near the heating point will accelerate aging, which will cause system shutdown if it is mild, and equipment and personal injury accidents if severe

[0003] At present, the commonly used forced heat dissipation measure is to place a fan at the hot spot as a heat dissipation device, but the air volume of the existing industrial fans on the market cannot be gathered, and the heat dissipation effect is not up to the requirement, and most of the materials used are carbon steel. Contact with electrical equipment during movement and movement increases the risk of equipment damage and personal injury
