AI Technical Summary
Existing transformer cooling methods are limited and have low efficiency, failing to provide sufficient heat dissipation under extreme temperatures. Furthermore, heat dissipation components are prone to dust and impurities, requiring frequent maintenance.
A low-noise, environmentally friendly oil-immersed transformer was designed, employing noise reduction and protection components and heat dissipation protection components, including an outer protective noise reduction frame, a breathable cover, a protective plate, a heat dissipation blower, and a filter plate. Air cooling is achieved through heat dissipation blowers installed on the inner and outer walls, and dust problems are solved by the simple installation and removal of the filter plate.
It effectively reduces noise, improves heat dissipation efficiency, prevents dust accumulation, and reduces maintenance frequency.
