Description

旋转电机的定子端板、旋转电机及其 该电机的冷却管的支撑和保护方法
技术领域：
本发明涉及旋转电机，诸如：同步电机、或双路馈电式电机，它可用于异步直流换流器级联上、外极电机上、同步流电机和交流电机，首先指电站中发电的发电机。本发明特别涉及和一个实施例相关的电机的定子，该实施例用来冷却定子齿，进而也间接地冷却定子绕组的绝缘导体。
现有技术：
传统上类似的电机是为6-30kV电压范围设计的，30kV一般被看成上限。这通常意味着发电机必须通过一个变压器才能连接在电网上，变压器把电压提高到电网电压水平，它大约在130-400kV的范围内。本发明涉及的电机是准备使用高电压的。这里应该明确，所谓高电压指超过10kV的电压。本发明装置的典型运行范围是从36kV直至800kV。其次，本发明也要用在电压低于36kV的所述技术领域中。
传统的空气冷却有两种不同的系统：空气通过轴和径向气道流过转子的径向冷却，和空气被轴扇吹入极隙(pole gap)的轴向冷却。定子被焊上的隔离片(通常是直的)分成径向气道。由于穿过定子叠片垛的轴向热导很差，气道必须做得很多。空气冷却的缺点在于，通风损耗经常很严重，定子必须加长来弥补通气道。通气道还减弱了机械结构，特别是在要讨论的长定子齿的高压发电机里尤其严重。
用定子轭中的冷却管进行轴向水冷却的方法为人熟知。必须用电绝缘的金属管以免使定子叠片垛间短路。它的缺点在于，如果绝缘坏掉，发电机可能会被因此出现的感应电流毁掉。在接口处焊或弯管子也很昂贵。另一个缺点是随时间变化的磁流会在金属管中引起涡流，结果当把它们用于电机时会产生一些能量损失。
一种导体可通过文献US 5 036 165了解，它的绝缘是由内外两层半导电的热解玻璃纤维提供的。也有人在直流电机里为导体提供此类绝缘，如象文件US 5 066 881描述的那样，一个半导电的热解玻璃纤维层与形成导体的两个平行杆相接触，定子槽里的绝缘物外又包上一层半导电热解玻璃纤维。之所以认为热解玻璃纤维材料合用是因为即便是浸漆处理完后它的电阻率也不改变。
发明目的：
利用高压绝缘导线，以下称之为高压线，它有和定子绕组中传送电力的缆(如XLPE线)相似的固体绝缘物，电机的电压可以提高到能直接与电网相连而无需线间变压器。这样传统的变压器就可以取消。这个想法一般要求定子中布线的槽比传统工艺来得深(高压带来厚绝缘层及增加了的绕组圈数)。这就在冷却、振动线圈端头的固有频率、齿和绕线各方面带来新问题。
本发明的目的在于提供一个带端板的旋转电机定子，端板使定子特别是所述类型旋转电机的定子齿得到直接冷却，所谓冷却是以在定子中轴向穿过冷却管的方式获得。定子板用来在定子的两端提供保护。组装过程中冷却管在定子两端受到的机械应力被本发明消除了。
本发明的另一目的是让定子板在组装时为冷却管做弯曲模板。本发明的其它有利的进展在下面的描述中会显现出来。本发明主要是要用到后面要详细定义的高压线，在那里它的优点会特别明显。
发明概述：
本发明涉及定子端板，它有关于旋转电机如高压交流发电机的轴向冷却，被冷却的部件包括定子及其叠片垛。特别是定子齿，间接地也包括定子绕组，该定子绕组在诸如高压交流发电机的旋转电机中。
板上设有与定子相应的轴向绕组槽和为冷却管进出准备的轴向的孔。板上还设安放弯曲部件的狭缝，冷却管将绕此部件打弯。端板上还设有安装槽，在端板的绕组槽出口处容纳密封部件。
本发明还涉及一种旋转电机，该电机包括上述定子端板。
本发明进一步涉及到一种旋转电机在其定子出口处沿第一个轴向孔支撑和保护冷却管的方法，其特征在于：设有弯曲部件的端板用于定子的端部，无论是安进定子上的第二个轴向孔还是从定子中延伸出来，冷却管都要在继续延伸前绕弯曲部件弯折。
在本发明的装置中，绕组最好是有固态模压绝缘层的一类导线，如现用于输电线的XLPE线或有EPR绝缘层的导线。这样的线包括一股或多股的内部导体，围绕导体的内半导电层，围绕它的固态绝缘层和围绕绝缘层的外半导电层。这类线是柔性的，此处这是个重要的性质，因为本发明的技术主要是基于绕组系统，其中绕组由在组装时被弯曲的线构成。一个30mm直径XLPE线的柔性一般对应一约20cm的曲率半径。80mm直径的线对应65cm的曲率半径。术语“柔性”在此表示弯曲在曲率半径为直径四倍时是柔性的，最好在八至十二倍。
制成的绕组应该在被弯曲或受到运行时的热应力情况下保持性能。在此各层保持附着至关重要。各层的材料特性是决定性的，特别是它们的弹性和相对热膨胀系数。比如，在XLPE线中绝缘层由交联的低密度聚乙烯制成，半导电层由掺入碳黑和金属粒子的聚乙烯制成。温度起伏引起的体积变化表现在线半径的变化，由于相对微小的各层间与材料弹性有关的热膨胀系数的差别，半径的膨胀不会引起层间粘合的破坏。
上述的材料组合只应被看成例子。其它满足此要求及为半导电体的要求的组合，自然也在本发明的范围之内。半导电体指电阻率在10-1-106ohm-cm的材料，比如1-500ohm-cm或10-200ohm-cm。
绝缘层可以，比方说，由硬质热塑料构成，有如：低密度聚乙烯(LDPE)、高密度聚乙烯(HDPE)、聚丙烯(PP)、聚丁烯(PB)、聚甲基戊烯(PMP)、交联材料如交联聚乙烯(XLPE)或橡胶如乙丙橡胶(EPR)或硅橡胶。
内外半导电层可以是同样的基本材料但有碳黑或金属颗粒掺入其中。
这些材料的机械性能，特别是它们的热膨胀系数，受是否掺入碳黑或金属粉的影响相对很小。至少在得到本发明所需的导电率的配比下是这样。这样，绝缘层和半导电层基本上有一样的热膨胀系数。
乙烯乙酸乙烯酯共聚物/丁腈橡胶、丁基接枝聚乙烯、乙烯丙烯酸丁酯共聚物和乙烯丙烯酸乙酯共聚物也可以是半导电层合适的多聚物。
即使用不同型的材料来做各层的基底，还是希望它们的热膨胀系数基本相同。上列材料的组合可以满足此要求。
上列材料有相对好的弹性，其弹性模量小于500Mpa，最好小于200Mpa。这样的弹性足以使各层材料热膨胀系数的小差别在径向弹性方向被吸收掉，这样就不会出现开裂或其它破坏，层间就不会脱离。层中的材料是弹性的，层间的粘合强度至少和材料中最弱的相当。
两个半导电层的电导率是以基本使沿层的电势相同。外半导电层的电导率则大得足以把电场围在电缆中，小得足以不使层的纵向电流引起严重的功率损耗。
于是，每一半导电层基本上构成一个等势面，它们基本上把电场围在层间。
当然，也可以在绝缘层里再加上一层或几层半导电层。

对本发明的说明：
图1代表一个定子上端板1，它设有10-12个径向排列的和定子相应的轴向绕组槽2，槽的数目决定于定子的设计，所述绕组槽形成一个径向链形槽3。定子端板上还设有为冷却管准备的进出狭口4和5，冷却管内有进出叠片垛的流动。定子端板1是扇形的，带有1个、两个或更多的链形槽。扇形互相靠在一起组成覆盖定子一端的圆盘(若电机的轴是垂直的便是上端)。板1还设有两个在链形槽3中径向排布的上铸槽6、7，以便在每一个绕组槽2在板1的出口处嵌入上密封部件8(在图1中只画了一个密封部件)。图1中还有一个横狭口9，它使冷却管在定子轭中穿行。还设有一个为机芯固定杆准备的燕尾槽10。
图2a代表定子下端板11。和图1中的定子上端板(10-12)一样，它也设有径向排列的和定子相应的同样数量的轴向绕组槽2。以同样的方式它们又形成径向链形槽。在定子下端板11上设有一个或几个回转狭口12，冷却管在此处走出叠片垛，转向后又进入叠片垛。正如前述的上板，定子下板11也设计成具有一个、二个或更多链形槽的扇形。扇形互相靠在一起形成整个覆盖定子一端的圆盘(若机轴垂直，此情况是下端)。定子端板11也设有在链形槽3中径向排布的下铸槽13、14，以便每一个绕组槽2在板1的出口处嵌入下密封部件15(只有一个密封部件见于图上)。从图上可见，这些密封部件依其所属板不同而有不同的形状。它们从板上突起的高度也视部件所起保护作用的不同而不同。定子下端板也设有为机芯固定杆准备的燕尾槽10。图2还显示出定子下端板11还有几个见于图2b的为灌注装置100所设的连接孔16，以及为固定栓准备的安装孔17。固定栓把板11固定在定子框架上一个环状的厚金属片上。
图2b代表在回转狭口12区域设有脐孔110的灌注装置100。灌注装置100通过连接螺栓120与定子下端板11相连。灌注装置100还有一个压在端板上、在冷却管硅嵌入点处的橡胶密封圈125。
嵌入密封部件的过程如下：在端板上接上一个圆柱形的灌注塞，把灌注物注入板上一个灌注进口，灌注物就会分布到导线的所有位置处。
灌注冷却管的过程如下：灌注装置封连在第一个薄板上，把硅压入冷却管的周围直至硅在上端板溢出。取下灌注装置放到另一个薄板上重复此过程一直到所有的冷却管都埋入硅中。这样冷却管在定子和端板里都埋入硅中。另外，灌注装置可重复使用。
有两个独立的灌注过程，一个是密封部件的灌注，另一个是冷却管的灌注。经常采用不同型的硅来完成这些过程。
图2c代表与本发明相关的高压线111的截面。高压线111由多股线112组成，比如铜线，有着圆形截面。这些股112置于高压线111的中心。股112周围是第一半导电层113。第一半导电层113周围是绝缘层114，如XLPE-绝缘体。绝缘层114周围是第二半导电层115。在此，高压线的概念不包括通常包裹动力线的那种外皮。高压线的直径在20-250mm之间，导电区的面积在40-3000mm2之间。
图3代表定子上端板1的铸槽6、7和注入灌注物的灌注口18。
图4代表俯视的定子上端板1，其中有在进狭口4里的冷却管的入孔19及为冷却管准备的第一个弯曲部件20。返回冷却管的各冷却管孔也见之于图，回转部件就在各孔之间。如图所示，出狭口5以相应方式设置，即，具有出孔24和相应的第一和第二弯曲部件20、23。进出狭口4、5还设有一个大直径的空腔25，该空腔在定子轭一侧，以便把冷却管接在一个大直径的管上，以提供进一步的保护。
在板的轴向截面上，图5显示一个绕组槽2和上铸槽6、7。
在板的径向截面上，图6显示从入孔19到空腔25的进狭口4。如图所示，第一个弯曲部件20比第二个弯曲部件23高，以使进入定子的冷却管比此板上回来的更接近表面，即，在进狭口4上冷却管是重叠放置的。
对定子上端板1而言，其厚度tu≥2Fr，这里Fr是冷却管的外径，以使板面能盖住冷却管。
图7显示定子下端板11的两个铸槽13、14及为注入灌注物而设的灌注口18。下板与上板的区别在于，板厚tl较小，铸槽13、14距离也较近。
图8是从外侧看到的定子下端板11，显示其回转狭口12，冷却管口19、21、22以及定子轭上的冷却管孔26。这些冷却管孔19、21、22、26都是板上为转回冷却管而开的口，而第三个弯曲部件27处于其中。
图8中板的轴向截面，图9显示一个绕组槽2和下铸槽13、14。截面还显示出下板设有为灌注装置准备的孔28。
图10是定子下端板11和一个在下面与其以固定栓29相连的厚金属板30的径向截面。图中显示第三个弯曲部件27凹入回转狭口12中，为灌注装置而设的连接孔也在图中。下板的设计使冷却管在板中转向。既然在下板中没安排进出口，则板厚可以保持最小。于是对定子端板11而言，板厚t1≥Fr，Fr是冷却管的外径，以使板面能盖住冷却管。
图11是定子31一部分的截面图，定子上有冷却管，定子芯32，一端还装有定子端板1。图上清楚地显示所有在狭口进出的冷却管33都潜在定子端板1内，以使它们免受机械应力。冷却管33还和输出介质的输入回路132以及输出介质的输出回路133相连。
图12显示所有的冷却管都和一个封闭的冷却管回路129相连，在此实施例中，它包括罐130，罐中盛有冷却剂131，可以是水、氢或其它冷却剂。罐130中装有一个水平指针来监控冷却剂的高度。罐130还和组成输入回路和输出回路的两个环形管相连。在输入和输出回路132、133之间连着许多平行的管线，其数目常相应于定子齿的数目或装有冷却管的齿侧的数目。平行管路134之一现于图12上。令冷却剂131从输入回路132开始，同时流经所有的平行管路134，循环到输出回路133，进而到达循环泵135、循环过滤器136、经过热交换器137，比如，片式热交换器，然后又回到输入回路132。来自水源的水通过热交换器137的一端，由交换器泵138通过一个过滤器(未画出)注入。水被泵过交换器流回水源。
定子端板最好用层压的材料制成。它们可以是整个的圆片而不像上述那样分成许多扇形。另外，定子里所有的冷却管都埋在硅橡胶中，以增加冷却管和叠片垛的热传导。
定子端板，无论上下，其轴向厚度t≥Fr，Fr是冷却管的外径。标记t在此代表tl或tu。
定子端板的第二和第三弯曲部件23、27分一步或两步弯转。两步弯转时每步转90°角，就像图6和10中那样。若冷却管的间距和弯曲圆的直径相同，则用一步弯转，这时转角为180°，即是个半圆。在进孔和出孔处的第一弯曲部件20，呈一步90°弯曲。弯曲部件20、23、27呈一或两步弯曲，每步包括一个90角。
