technical field

The utility model belongs to the field of wind power generating devices, in particular to a resistance type vertical axis wind power generator.

Background technique

Breeze wind turbines are mainly used in wind-solar complementary independent power systems. The wind turbines used in the wind-solar hybrid independent power system use more vertical axes.

At present, the technology of vertical axis fans at home and abroad is still immature. The advantages of vertical axis fans are small start-up wind speed, low operating speed, low noise, and less maintenance. In the southern region with only 3m/s, the power generation effect is not good, which limits the rapid development of wind-solar complementary independent power systems.
