Description

一种无刷电励磁同步风力发电机组
技术领域：
本实用新型属于风电设备领域，涉及一种风力发电装置，尤其是一种无刷电励磁同步风力发电机组。
背景技术：
现有风力发电机中采用了碳刷和滑环装置，向转子绕组中输入或输出电流。在运行过程中，碳刷和滑环一直处于磨损状态，必须定期维修和更换，这就增加了风机的维护成本。碳刷磨损后产生的碳粉，不仅对机舱环境造成污染，而且增加了滑环装置的故障率。
实用新型内容：
本实用新型的目的在于克服上述现有技术的缺点，提供一种无刷电励磁同步风力发电机组，包括叶轮1、轮毂、主轴和齿轮箱2；所述无刷电励磁同步发电机3的一端通过联轴器与齿轮箱2高速轴连接，另一端安装有励磁单元8和全功率变流器4；所述全功率变流器4通过主断路器5和熔断器6与变压器7连接。
本实用新型的无刷电励磁同步风力发电机组采用无刷电励磁同步发电机3，从而取消现有技术中的碳刷和滑环，从而大大减少了风机的故障和维护时间。
附图说明：
图1为本实用新型的无刷电励磁同步风力发电机组结构示意图。
其中：1为叶轮、2为齿轮箱、3为无刷电励磁同步发电机、4为全功率变流器、5为主断路器、6为熔断器、7为变压器、8为励磁单元。
具体实施方式：
下面结合附图对本实用新型做进一步详细描述：
参见图1，一种无刷电励磁同步风力发电机组，包括叶轮1、轮毂、主轴和齿轮箱2；所述无刷电励磁同步发电机3的一端通过联轴器与齿轮箱2高速轴连接，另一端安装有励磁单元8和全功率变流器4；所述全功率变流器4通过主断路器5和熔断器6与变压器7连接。
以上内容是结合具体的优选实施方式对本实用新型所作的进一步详细说明，不能认定本实用新型的具体实施方式仅限于此，对于本实用新型所属技术领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干简单的推演或替换，都应当视为属于本实用新型由所提交的权利要求书确定专利保护范围。
