Description

technical field [0001] The invention relates to the technical field of wind power generators, in particular to a wind power generator based on a tapered structure sleeve to realize smooth start. Background technique [0002] Wind energy is a kind of available energy provided to human beings due to the work done by air flow, which belongs to renewable energy. People use windmill blades to convert wind energy into rotation to drive generator sets to generate electricity, that is, wind power generation. However, there is instability in the wind force. When strong wind hits, it takes only a short time for the blades of the windmill to never turn to fast rotation, that is, to have a relatively fast acceleration. Excessive acceleration will cause a large impact between the mechanical parts, which will easily lead to damage to the parts; at the same time, the large acceleration will cause the generator set to generate excessive inrush current in a short time, which will easily dam...

However, there is instability in the wind force, when a strong wind hits, it only takes a short time for the blades of the windmill to turn from fast to fast, that is, to have a relatively fast acceleration

Excessive acceleration will cause a large impact between the mechanical parts, which will easily lead to damage to the parts; at the same time, the large acceleration will cause the generator set to generate excessive inrush current in a short time, which will easily damage the electrical equipment of the generator set and reduce the power generation.
