图2示出了本发明一个实施例中海上双馈发电机滑环冷却系统的结构示意图。
具体实施方式
应当指出，各附图中的各组件可能为了图解说明而被夸大地示出，而不一定是比例正确的。在各附图中，给相同或功能相同的组件配备了相同的附图标记。
在本发明中，除非特别指出，“布置在…上”、“布置在…上方”以及“布置在…之上”并未排除二者之间存在中间物的情况。此外，“布置在…上或上方”仅仅表示两个部件之间的相对位置关系，而在一定情况下、如在颠倒产品方向后，也可以转换为“布置在…下或下方”，反之亦然。
在本发明中，各实施例仅仅旨在说明本发明的方案，而不应被理解为限制性的。
在本发明中，除非特别指出，量词“一个”、“一”并未排除多个元素的场景。
在此还应当指出，在本发明的实施例中，为清楚、简单起见，可能示出了仅仅一部分部件或组件，但是本领域的普通技术人员能够理解，在本发明的教导下，可根据具体场景需要添加所需的部件或组件。另外，除非另行说明，本发明的不同实施例中的特征可以相互组合。例如，可以用第二实施例中的某特征替换第一实施例中相对应或功能相同或相似的特征，所得到的实施例同样落入本申请的公开范围或记载范围。
在此还应当指出，在本发明的范围内，“相同”、“相等”、“等于”等措辞并不意味着二者数值绝对相等，而是允许一定的合理误差，也就是说，所述措辞也涵盖了“基本上相同”、“基本上相等”、“基本上等于”。以此类推，在本发明中，表方向的术语“垂直于”、“平行于”等等同样涵盖了“基本上垂直于”、“基本上平行于”的含义。
另外，本发明的各方法的步骤的编号并未限定所述方法步骤的执行顺序。除非特别指出，各方法步骤可以以不同顺序执行。
首先阐述本发明所基于的原理，本发明人通过研究发现，海上风力发电机的滑环容易损坏的一个重要原因是，目前滑环要么从海上环境直接引入冷却风进行冷却，要么采用机舱冷却风或机舱环境风进行冷却，其中机舱冷却风或机舱环境风是从海上环境中直接引入的；而在海上或相似潮湿环境下，滑环系统的从海上环境引入的冷却进出风会使得滑环部件长期处于潮湿的盐雾环境中，而潮湿的盐雾环境进而会引发滑环、碳刷以及氧化膜腐蚀，由此影响滑环系统的可靠运行；此外，发明人还发现，当滑环系统停止运行时，进出风无防护的冷却系统会导致滑环表面较容易产生凝露，引起滑环表面腐蚀，且当滑环系统重新运行时容易产生打火烧蚀。本发明人通过进一步研究发现，通过将对冷却滑环的冷却风进行过滤以除去盐雾成分并且将滑环与机舱冷却系统解耦，使得冷却滑环的冷却风与机舱冷却系统没有直接的气体交换，可使滑环基本上免受盐雾环境的损害并避免滑环表面产生凝露，由此大幅提高滑环寿命。在本发明中，术语“解耦”是指滑环的冷却风与机舱的环境空气或冷却风没有直接的气体交换，例如可以将它们彼此隔离以防止气体交换。
下面结合具体实施方式参考附图进一步阐述本发明。

所述滑环箱202中可以具有加热器，所述加热器可以在所述滑环部件201停止运转、所述海上双馈发电机滑环冷却系统停机时加热所述滑环箱202内的气体，配合进风口连接的过滤系统及冷却风扇206可以有效阻止外界空气从前端进入，同时配合出风口连接的尾部关闭的百叶窗208也可以有效阻止外界气体从后端进入，有效避免外界环境的影响。
在本发明一个实施例中还提出一种利用所述海上双馈发电机滑环冷却系统冷却滑环的方法，该方法包括下列步骤：
由冷却风扇206驱动空气依次经过雨水分离器203、初效过滤棉204以及中/高效过滤棉205，其中所述雨水分离器203过滤水汽以及过滤大于15um的灰尘颗粒、所述初效过滤棉204过滤粒径小于15μm，且大于等于4μm灰尘颗粒，所述中/高效过滤棉205过滤粒径小于4μm，且大于等于0.4μm灰尘颗粒以及过滤盐雾；以及
