Main transformer radiator intelligent frequency conversion fan with photovoltaic conversion function and using method thereof

Abstract

The invention relates to a main transformer radiator intelligent frequency conversion fan with a photovoltaic conversion function and a using method thereof. The main transformer radiator intelligent frequency conversion fan comprises a main transformer body and an oil flow radiator communicated with the main transformer body. The main transformer radiator intelligent frequency conversion fan with the photovoltaic conversion function is characterized in that the main transformer radiator intelligent frequency conversion fan connected with a photovoltaic conversion system is mounted on the oil flow radiator, the main transformer radiator intelligent frequency conversion fan is connected with a control module, the control module is used for automatically starting and stopping the main transformer radiator intelligent frequency conversion fan through the temperature tested by an on-line oil temperature thermoscope connected to the main transformer body according to a preset oil temperature value. The main transformer radiator intelligent frequency conversion fan and the using method thereof are reasonable in design, capable of achieving energy saving and environmental protection, and capable of effectively solving the radiation problem under long-time working of the main transformer body.

Description

technical field [0001] The invention relates to a cooling fan device, in particular to an intelligent variable frequency fan for a main transformer radiator with a photovoltaic conversion function and a control method thereof. Background technique [0002] During the operation of the main transformer, due to the electromagnetic effect, its internal winding will generate a lot of heat, which needs to be cooled by transformer oil, otherwise it will cause a vicious accident of burning the main transformer. The heated transformer oil used to cool the main transformer winding will flow The radiator installed outside the main transformer is cooled by the forced air blowing of the radiator fan, and the cooled transformer oil enters the main transformer body to cool the main transformer windings, and the cycle repeats. The traditional main transformer radiator fan widely used now consumes a lot of power for long-term daily operation, and the traditional main transformer radiator fan...

AI Technical Summary

Problems solved by technology

The traditional main transformer radiator fan widely used now consumes a lot of power for long-term daily operation, and the traditional main transformer radiator fan does not have the intelligent frequency conversion function. Adjustable, and emergency stop and emergency opening are easy to damage

These defects of the traditional main transformer radiator fans are widely used above, resulting in high energy consumption, high noise, easy damage, heavy maintenance and repair workload, and short life. This has caused greater direct and indirect economic losses, as well as adverse social impacts caused by power outages
