Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary mechanisms for transformers, and particularly relates to an air guide trough with an adjustable blowing angle. Background Technology

[0002] When the temperature of a dry-type transformer exceeds its insulation withstand temperature, the insulation will be damaged, affecting the safe operation and service life of the transformer. Therefore, dry-type transformers must be equipped with appropriate cooling devices to keep the winding temperature within the allowable range. Common cooling methods for dry-type transformers include natural air cooling and forced air cooling. Forced air cooling fans are generally installed at the bottom of the dry-type transformer, below the transformer coils. Cool air is then blown directly into the transformer coils, carrying away the heat inside the coils and greatly improving the heat dissipation effect. To ensure a safe air gap, the fans of 20kV and 35kV dry-type transformers are generally located far from the high-voltage coils, which makes the original fan structure unable to meet the air cooling requirements of dry-type transformers.

[0003] Most of the airflow is blocked by the transformer's lower clamp, preventing it from reaching the high and low voltage coils. This makes it impossible to meet the forced air cooling requirements of dry-type transformers. To overcome the shortcomings of the existing technology, this invention provides an adjustable air guide channel. Utility Model Content

An adjustment component is installed at the upper end of the mounting bracket 3. The adjustment component is located at the upper end of the air outlet of the fan 4 to facilitate the adjustment of the airflow direction. The adjustment component includes a support frame 5. There are two sets of support frames 5. The two sets of support frames 5 are respectively installed at the upper end of the mounting bracket 3. Multiple adjustment components for adjusting the airflow direction are movably installed on the side wall of the upper end of the support frame 5.

[0024] The upper side wall of the support frame 5 is provided with multiple sets of fixing components for fixing. The number of fixing components and adjusting components is the same, and they are placed opposite each other. The fixing components are provided with multiple sets of fixing holes 6 and limiting holes 7 for limiting. The multiple sets of fixing holes 6 are evenly distributed in an arc shape with the limiting holes 7 as the center.

[0025] The adjusting component includes an air guide groove 8 and a rotating component 9. A limiting rod 10 is installed on the side wall of the air guide groove 8. The limiting rod 10 is movably connected through a limiting hole 7. A retaining member 11 is provided on the side wall of the end of the limiting rod 10 away from the air guide groove 8. The rotating component 9 is movably engaged with the end of the limiting rod 10 away from the air guide groove 8. A connecting rod 12 is installed on the side wall of the rotating component 9.
