Problems solved by technology

On the other hand, using the mechanical energy of the rotating fan shaft to provide power for the compressor of the refrigeration system can get rid of the dependence of the refrigeration system of the superconducting wind turbine on external power, and it is possible to realize the superconducting wind turbine without external power input. The black mode start of the traditional superconducting wind turbine effectively solves the problem that the traditional superconducting wind turbine must be powered by an external power grid to make the refrigeration system work, and the excitation can only be performed after cooling down to a suitable temperature.

Abstract

The invention particularly relates to a shaft power input superconducting wind power generator refrigerating system which comprises a fan spindle, a compressor, a refrigerator cold head, a speed adjusting mechanism, a superconducting magnet, a cooling capacity transmission mechanism, a magnet heat-insulating supporting structure and a fixed support. The superconducting magnet, the compressor and the speed adjusting mechanism are mounted on and synchronously rotates with the fan spindle, the superconducting magnet is connected onto the fan spindle through the magnet heat-insulating supporting structure, the superconducting magnet, the cooling capacity transmission mechanism, the refrigerator cold head and the compressor are sequentially connected, and the compressor is connected to the speed adjusting mechanism which is connected with the fixed support. The shaft power input superconducting wind power generator refrigerating system is especially suitable for superconducting generators high in power, low in rotating speed and large in torque, part of output power of the fan spindle is utilized to provide power for the refrigerating system compressor to realize black-mode start of a superconducting wind power generator under the circumstance without outside power source input, gas circuit connection between moving parts and rotating parts is completely avoided, a rotary sealing structure is not needed basically, and reliability of the system is improved.

Description

technical field [0001] The invention relates to a superconducting motor refrigeration system, in particular to a shaft power input superconducting wind power generator refrigeration system. Background technique [0002] As an emerging technology, superconducting technology has gradually shown irreplaceable advantages in power applications. The fan manufactured by superconducting technology has a rotor wound by high-temperature superconducting (HTS) wire, and its current-carrying density can be increased by about 150 times compared with conventional copper wire, making superconducting motors have extremely high energy density. On the one hand, the volume of the motor is greatly reduced. At the same time, because the superconducting coil can generate a very strong magnetic field, the iron core in the motor can be omitted, and the weight of the motor is also reduced a lot. According to the estimation of American Superconducting Corporation, the weight of 10MW superconducting d...
