Abstract

The invention provides a direct-driven permanent magnet synchronization disc multi-combination large-power vertical type wind generating set which comprises a set base, a first shell, a second shell, a third shell, a fourth shell, a fifth shell, a set end cover, a set of power fan blades, a main control station arranged in the shells, a first set platform, a staircase, a second set platform, a third set platform, a hydraulic station platform, a hydraulic station and a main power shaft. Three pairs or multiple pairs of first sets, second sets and third sets are arranged on the two sides of the main power shaft, wherein the first sets, the second sets and the third sets are mutually matched. The sets are connected with the power fan blades through a first universal joint, a second universal joint and a third universal joint, and the five shells from the first one to the last one are fixedly connected through set screws. The direct-driven permanent magnet synchronization disc multi-combination large-power vertical type wind generating set is high in efficiency, the effect that a generator is brushless is achieved, the power factor of a power grid is improved, a gear box is removed, the efficiency and reliability of the wind generating set are improved, maintenance quantities of equipment are reduced, and noise pollution is reduced.

Description

technical field [0001] The invention relates to a direct-drive permanent-magnet synchronous disc-type multi-combination high-power vertical wind power generating set. Background technique [0002] Currently common cage asynchronous generators and doubly-fed asynchronous generators, due to the presence of gearboxes. There are also carbon brushes and slip rings in double-fed asynchronous generators, which make the system costly, poor in reliability, large in maintenance, and serious in noise pollution, and low in efficiency when it operates at low load, especially as the capacity of a single machine increases. The problem is more prominent. Therefore, direct drive and brushless have attracted more and more attention. Contents of the invention [0003] In order to solve the problems of the above-mentioned background technology, the present invention provides a high-power, high-efficiency, low-noise, multi-combination variable-speed operation, variable pitch adjustment, low-...
