The invention provides a high-efficiency large-scale oil-immersed rectifier transformer air cooling device, comprising a sliding plate structure, a connecting plate structure, a dustproof net structure, a motor, fan blades and an oil-immersed rectifier transformer. A sliding plate structure bolt is mounted on the outer wall of the oil-immersed rectifier transformer. One end of the connecting platestructure is connected with the sliding plate structure, and the other end is connected with the dustproof net structure. The motor is installed inside the dustproof net structure. The fan blades aremounted on a motor output shaft. Beneficial effects of the device are that cooperated arrangement of the sliding plate structure and the connecting plate structure, positions of the dustproof net structure, the motor and the fan blades can be conveniently moved, being more convenient for heat dissipation of different parts of the oil-immersed rectifier transformer. Through arrangement of the dustproof net structure, dust is prevented from contaminating the oil-immersed rectifier transformer, and heat dissipation effect of the air cooling device of the large oil-immersed rectifier transformeris increased.
Description
technical field [0001] The invention belongs to the technical field of transformer air-cooling devices, in particular to a high-efficiency large-scale oil-immersed rectifier transformer air-cooling device. Background technique [0002] The load of the large oil-immersed rectifier transformer is a large-capacity frequency conversion rectifier + large motor. The load is generally a periodic shock load. Since the frequency conversion rectifier is a non-sinusoidal power receiving device for the grid, even if the grid supply voltage is an ideal sine wave, due to the one-way conduction of the rectifier tube on and off, the current drawn by the rectifier from the grid is also a non-sinusoidal current waveform . This kind of harmonic current flows through various impedance components in the system, including motors, transmission lines and transformers, and will inevitably produce non-sinusoidal voltage drops, which will pollute the current and voltage waveforms in the AC power sys...
