Abstract

The invention relates to 'repulsive magnetic component, full permanent magnetic and full suspending bearing and compound wind power photovoltaic power system', in particular to a magnetic bearing and a wind power system, wherein, the repulsive magnetic component is arranged on a vertical main shaft. The invention is characterized in that the wind power system comprises an upper repulsive body and a lower repulsive body which are formed by homopolar ring permanent magnets; the upper repulsive body is formed by a piece of hollow ring permanent magnet while the lower repulsive body is formed by a piece of inner ring permanent magnet and a piece of outer ring permanent magnet arranged in a certain radial distance from the inner ring permanent magnet; the hollow ring permanent magnet is positioned in the effective magnetic range of the magnetic force of the two pieces of permanent magnets forming the lower repulsive body. By adopting the full permanent and full suspending bearing of the repulsive magnetic component, and arranging a pull-push magnet component at the upper end of a spiral body of a vertical shaft wind turbine and the repulsive magnetic component at the lower end of the spiral body, the full magnetic and full suspending support of the main shaft or a vertical shaft impeller can be realized, thus eliminating all friction of the spiral body of the wind turbine.

Description

Technical field: [0001] The invention relates to a renewable energy utilization device, in particular to a full-permanent-magnet full-suspension bearing using a repelling magnet assembly, a wind power generator and a combined wind-power photovoltaic power generation system using the bearing. Background technique: [0002] Wind energy is a clean natural resource that comes from a wide variety of sources. Using wind energy to generate electricity has the characteristics of no pollution and low maintenance costs. Wind power has become one of the world's important energy sources and development directions. However, due to reasons such as mechanical friction and mechanical momentum, the starting wind speed has become the main bottleneck restricting the scope and timing of wind energy resource utilization. A large number of low-speed wind energy resources cannot be utilized. Due to the instability of wind energy resources, the efficiency of wind turbines is often insufficient. ...
