弹性套管支撑件及弹性套管的包覆方法
本发明涉及一种使弹性套管呈扩张状态的弹性套管支撑件以及弹性套管的包覆方法，该弹性套管用于如电缆接头或类似物之类的细长圆柱形部件。
用于包覆细长件、尤其如中-高压电缆接头的细长件的部件，有已知的有弹性套管，术语也称之为自收缩或冷收缩弹性套管，以区别于其他类型的弹性套管如热收缩套管。这类套管含有弹性管状结构(在其中含有全部的为特殊用途所必需的功能部件，如电场控制层、绝缘层等)，该弹性管状结构在使用以前呈扩张状态，以便使其能够套在被包覆的部件上而在应用以后，它就或多或少以强制的方式弹性地套装在该部件上。
为了保持套管呈扩张状态，采用管状圆柱支撑件，使管状弹性结构在弹性扩张状态下套装在该支撑件上。一旦当套管定位在被保护的部件上时，就除去支撑件，使套管弹性地收缩在该部件上。
现已知道的有不同类型的支撑件。最普通的是由带子组成的管状圆柱支撑件，而该带子被螺旋地绕制成并排的且以多种方法相互连结的圈。这种类型的支撑件已在GB-A-1292608、US-A-4389440、EP-A-0291203中被披露过。通过牵引带子而使带子逐步地开卷，从而逐步地破坏支撑件，以此来除去支撑件。当然，牵引从内部产生即被牵引的带子的一端穿过支撑件内侧，直到它在另一端出现为止。的确，已经收缩并紧固在被保护的圆柱部件上的那部分套管阻止被开卷的带子的通过。
通常用合适的聚合材料的管子开始进行支撑件的制作，该管随后经螺旋切割以限定带子。在GB-A-1292608和EP-A-0291203中所描述的支撑件就是这种类型。作为另一种方式，支撑件能用合适的聚合材料的带子构成，将该带子螺旋绕制，接着使其局部熔化，以便熔接相邻的圈。在US-A-4389440中描述的支撑件就是这一类型。
这种类型的支撑件必须具有一定的必要条件，以便正确地完成所需的功能。
第一，支撑件外表面必须平滑，以免损坏套管。实际上，在储存期间，因弹性扩张而由套管施加的强压会在套管内表面上永久地重现支撑件外表面的任何凹凸不平(即在除去支撑件时不能完全地弹性复原，或者对于合格的套管运用来说复原的时间太长)。
第二，支撑件必须具有一个径向抗压强度，以便即使在储存温度下也能够长时间地抵抗外套管压力而不受损坏。在用于中-高压电缆接头时，由套管施加的压力很容易达到近1MPa的水平。
具体地讲，现已知道，经受均匀压力之圆环的单位长度的临界压力σcr为：
σcr=3EJ/R3    (1)
其中E为弹性模量，J为惯性矩，R是环的内半径(参见Timoshenko andGere“弹性稳定性理论”，McGraw Hill第二版第289页以及其后诸页)。在此，惯性矩J按下式计算：
J=S3/12    (2)
其中S为环的厚度(见上述文章第282页)。
管状支撑件的厚度由以下要求决定，即确保有足够的对外部压力的阻抗，以便防止该部件受损坏。
第三，带子的抗拉强度以及使各圈连在一起的韧性必须能使支撑件可按指定方式拆卸，同时，要绝对防止施加到带子上的拉应力不使带子逐步地开卷，而使带子撕裂。如果这样就需要除去起初使用的套管，开始用新套管运行。
例如，偶尔也有用均质塑性材料做的支撑件，其中的螺圈由螺旋盲槽纹限定，该盲槽纹在原管状部件上形成，因为重要的是在加工过程中在槽纹底部保持恒定的剩余厚度。该剩余厚度必须足够的小，以便在牵引力作用下可以使其撕裂而不致于引起带子断裂，但该剩余厚度不使槽纹穿透，也不危及支撑件的完整性。例如，由于原管状部件的尺寸缺陷，或者由于槽纹加工时存在的不足而造成的过量剩余厚度会引起为使带子开卷而施加到带子上的牵引力局部增加，并有可能引起断裂。
第四，带子必须具有最小尺寸，使其在开卷期间，可以容易地通过支撑件内表面与受保护部件外表面之间的空间。带子尺寸的减小也是重要的，以便使相同的套管可用在具有尽可能宽的直径范围的部件上。实际上，如果给出了某一套管，所要被保护的部件的最小直径只取决于套管的弹性收缩容量。最大直径取决于在支撑件内可获得多大空间，这要考虑到带子在其开卷期间也必须能够通过要被保护的部件以及支撑件的内壁之间。
最后，必须限制圈数以尽可能缩短开卷时间。实际上，带子开卷操作要求进行直线牵引并每膈一段时间间隔进行开卷带子的部件的周期转动。另外，由于开卷的带子的点跟随卷绕支撑件的螺旋线，因而开卷的带子在该部件上趋于逐渐扭结并且阻止了进一步开卷。带子完全开卷所需的转数理论上等于圈数，尽管在实际中由于正常的转动对于开卷操作的末尾来说是多余的而使开卷所需转数较小。大的圈数意味着要开卷很大长度的带子以及需要进行大量的转动。
因此问题在于提供上述类型的支撑件，并且使它尽可能多地满足上述的需要。
所以，在第一个方面，本发明涉及一种使弹性套管呈扩张状态的支撑件，该弹性套管用于包覆如电缆接头或类似物的细长圆柱形部件，该支撑件包括并排地螺旋卷绕成圈的带子，以致该支撑件呈现为圆柱管状形式，本发明还涉及在圈之间相互约束以便把带子固定在卷绕状态的装置，其特征在于带子和约束装置由不同材料制成。
带子与约束装置的材料之间的区别允许两者具有最大的选择自由。
较好的是该带子由弹性材料制成，该弹性材料具有至少为150,000MPa的弹性模量，其中各圈之间的相互约束装置包括在相邻各圈之间热熔接的带子上的一层热塑包覆材料。
热塑性材料通过热熔接使约束装置容易地得以实现，同时，已经证实如果带子材料具有高模量弹性，甚至减小带子的厚度也能确保支撑件抵抗套管压力所需的阻力。带子厚度的减小允许支撑件所占据的径向空间较小以及在开卷期间带子所占据的空间较小，因此在支撑件和电缆外皮之间需要较小空间。
有利的是，弹性材料是钢材并且较好的是谐波的弹簧钢。由于其大约210,000MPa的、基本上不受时间的影响并且对环境温度的增加不敏感的高模量弹性因而这是一种适用于该目的的材料。此外，它是经济的并可以方便地获得。
对于这种材料，把上述的公式(1)和(2)应用于由具有厚度S=0.5mm，卷绕半径R=25mm的条带制成的带子中得出σcr=0.42MPa的临界压力。对于0.6mm的厚度，运算得出临界压力为σcr=0.72MPa。令人吃惊地发现采用厚度仅为S=0.3mm的带子，可获得能经受住用于中压电接头的具有所测压力约为0.7MPa的弹性套管而不发生断裂的支撑件。
较好的是带子在静止时处于基本上直的状态，在移走各图之间的相互约束装置之后该带子趋于回复到该基本上直的状态。这大大方便了支撑件的拆除，因为在牵引支撑件时这有利于带子在支撑件中呈直线的布置。
在随意地放入一种粘合剂的情况下，可以通过挤压便利地把热塑性材料应用到带子上。用这种方式，可以以结构简单的方式获得该热塑性材料对带子的极好的粘合。
在第二方面本发明涉及实现使应用于包覆如电缆接头和类似物的细长的圆柱形部件的弹性套管处于扩张状态的支撑件的方法，其特征在于它包括下列步骤：
-在圆柱形轴上以并排着的圈螺旋地卷绕一带子，并且
-通过由不同于带子的材料制成的约束装置相互约束并排的圈。
该方法允许以与带子的材料无关的方式来控制各圈之间的约束。
较好的是该方法也包括下列步骤：
-提供由具有至少150,000MPa的弹性模量的弹性材料制成的带子，
-在这种带子上挤压一层热塑性包覆材料，
-在该轴上卷绕带着被挤压的包覆层的带子，
-加热该包覆层直到热塑性材料的软化极限，
-在冷却之前对该包覆层施加压力以获得相邻各圈的热熔接。
较好的是，该方法也包括在带子上挤压包覆层之前在带子上施加一层粘合剂的步骤。这确保了把热塑性包覆层粘合到带子上的最大粘稠性。
本发明的另外特征和优点可通过以下的、参照附图给出的本发明的支撑件的较好实施例的描述而变得更加清楚，其中：
图1示出本发明的支撑件的透视剖视图，用图示出弹性套管装配在其上，
图2示出图1的支撑件的带子的两相邻部分的透视剖面视图，并且
图3示出实现图1的支撑件的设备的示意透视图。
在这些图中，参数1表示使弹性套管M处于扩大状态的支撑件的整体，该弹性套管M仅在图1中用图表示。该支撑件不论在图1中所示已完成还是在图3中所示正在生产中都由1来表示。
支撑件1由以并排的圈3螺旋地卷绕的带子2制成，以致使该支撑件呈现圆柱形管状。带子2具有包缠带子2的整个截面的包覆层5。
相邻的圈3在支撑件1相应的外部沿熔接线6被热熔接在一起。在支撑件1相应的内部，相邻圈3只靠在一起，即由切口7分割。
带子2具有开卷端8，该开卷端在支撑件1内与支撑件的一端相对地折回并在该支撑件1内以直线延伸，直到它从另一端露出为止。
带子2由具有大于150,000MPa的高模量弹性的弹性材料制成。该弹性材料较好为钢材，但更好为谐波弹簧钢。该材料的弹性模量约为210,000MPa，该模量甚至在如潮湿和高温的恶劣环境状态下仍能维持不变。
由于该材料的弹性模量，带子2能有非常小的厚度S，对于采用中-高压电接头包覆套管，相信带子2的厚度较好地可在0.2mm到0.8mm之间。
包覆层5具有热塑性材料，最好采用通用技术通过挤压并以厚度为0.1mm-0.2mm把热塑性材料施加在带子2上。热塑性材料可从种类繁多的易挤压的聚合材料中选择，例如塑化聚氯乙烯(PVC)，高或低密度聚乙烯(PE)，聚酰胺，乙烯乙酸乙烯酯共聚物(EVA)，乙烯乙酸乙酯共聚物(EEA)，丙烯酸乙丁酯共聚物(EBA)，乙酸丙烯酸类共聚物(EAA)等等。
通过在钢上挤压上述材料实现的粘合其本身是好的，但是通过在挤压之前在带子2上施加一层粘合材料能够改进粘合，所采用的粘合材料例如为所谓速溶型的粘合剂，例如氰基丙烯酸类或所谓热溶型，例如带有聚酰胺基或EVA共聚物基的类型。
作为应用一层粘合材料的变化形式，通过为包覆层5采用一种选自上述的、带有特定粘合特性的聚合物的材料能获得所需的粘着力。这些聚合物能粘合于许多表面，无论是金属的还是聚合物的表面，特别是它们能很好地粘合于钢上。此外，不管其粘性如何，这些聚合物易于挤压。
这些粘合的聚合物的实例为EAA、EVA以及聚酰胺。特别是称为DOW化学公司的PRIMACOR3442的一种EAA共聚物已经被试验。另一种EAA共聚物被叫做Dupont公司的NUCRELARX48。通过将通用的挤压机挤压出熔融温度为180℃到280℃之间的聚乙烯，可获得对钢带极好的粘合而不需放入任何粘合剂。EAA的机械的以及热的特性与低密PE的特性十分相似因此，支撑件的特性以及其构造程序完全相同。
按下面方式构造支撑件。首先通过挤压把包覆层5施加在带子2上。已包覆的带子能直接用于生产支撑件1或甚至绕在卷轴上存储。用层5包覆的带子1被卷绕在转动且轴向移动的轴9上同时注意逐渐形成的圆圈3彼此相邻。这以公知的方式通过适当地选择和控制轴9的转速以及横移速度来实现。在带子2被卷绕期间刚形成的圆圈3通过一个加热系统(图3中作为一鼓风机10示出)加热并且由拉直辊11加压。这导致了在相邻圆圈3之间熔合线6的形成。在达到支撑件1所需的轴向长度之后停止喂入带子2，该带子2由一切割设备(图3中作为刀片12示出)切割，并将该支撑件1从轴9上拉出。带子2的仍然是自由的端部8在支撑件1中折回并在相反端露出。
在实际中采用厚度S为0.3mm以及宽度L为3mm的谐波弹簧钢制成的带子2。对于包覆层5采用在带子2上以130℃挤压的低密PE(Enichem公司的RIBLENE MV10)，在挤压之前在带子2上施加氰基丙烯酸类粘合剂(LOCTITE 406)。接着将被包覆的带子绕在一根轴上。在卷绕期间外表面被加热到150℃并且被加压以获得圆圈3的热熔接。
已经发现这样构成的支撑件1能经受住0.7MPa的径向外压力。带子2能经受住300N的拉伸应力而不断裂。包覆层5的熔接线6的强度证明是基本上可忽略的。另外，在分离带子2的圈3时，包覆层5的热塑性材料的撕裂不会留下分离片，如果这些分离片落在套管和要被保护的部件之间会损坏套管的功能。
如上所述，本发明与现有技术相比可获得很大的好处。
第一，由支撑件所占据的径向空间明显小于已知支撑件的径向空间，正如由开卷期间的带子所占据的空间明显小一样。这允许对具有相当大范围的直经的部件采用相同的套管。
此外，带子的高强度完全避免了开卷期间带子断裂的危险。将不同材料用于带子以及圈的约束装置允许选择具有高弹性模量以及高拉伸强度的材料的带子以及具有低抗撕裂性的材料的约束装置，从而使支撑件的正确操作从正如由均质的材料制成的已知支撑件可能发生的尺寸的临界特性中摆脱出来。
此外，一旦从熔接线的约束中摆脱出来，带材的弹性趋于使带子回复到松驰状态，这样便于使带子从套管的相反端拉出并且减小了绕着被保护的部件扭结的危险。
也应注意由于带子一直由基本软的且不切割的热塑性材料包覆，既使带有能切割的尖缘的带子在开卷期间也不能对套管或要被保护的部件造成任何损坏。
最后，根据本发明实现支撑件是非常简单的，特别是只通过把带子绕在具有不同直径的各个轴上就能获得不同直径的支撑件。
实例
为了用于带有挤压的绝缘材料的中压电缆，在法国所称的尺寸(参见Electricite de France标准HN33S23的表1)在最小横截面积(50mm2)电缆的绝缘材料上的最小直径19.9mm与在具有最大导体横截面积(240mm2)的电缆的外皮上的最大直径44.5mm之间变化。
根据本发明的支撑件具有49mm的外径以及约48mm的内径，用厚度约为0.3mm而宽度为3mm的钢带包覆一层如上所述的厚度约为0.1mm-0.2mm的低密聚乙烯来实现该支撑件，以确保约束已卷绕的带子圈。具有内径为14mm的弹性套管在所述支撑件上扩展。
接头由具有多层EPR基化合物的几层套管组成。特别是接头是由从内向外具有场控制层、绝缘层以及半导体层的内套管组成的装置。再向外有以负性公差配合的半导体外皮、一个呈铜编织物形式的防护罩，以及一个在前述层上以负性公差配合的弹性保护外层，这些前述层的侧边反回以便把接头安装在电缆上。
用于不同层的化合物的网状结构的程度对于所有层来说为95％-100％。
处于静止状态的套管的总厚度约为17mm、平均弹性模量约为15NPa。该管状支撑件具有550mm的长度而套管具有450mm的长度。
套管上的扩张为250％，其对应的管状支撑件上的压力约为0.7MPa。
48mm的支撑件的内径与由在支撑件内的约1mm的带子所占据的空间相结合，该内径允许在具有445mm直径的最大导体横截面(240mm2)的电缆的外皮上装配该部件。
由支撑件上的扩展套管形成的装置在65℃下保持6周的时间，模拟在环境温度(20℃)下存储2年的情况。在此期间管状支撑件末出现明显的结构上的屈服或变形。
接着根据上述程序通过牵引带子自由端，把套管应用在具有最小导体横截面积(50mm2)的、与19.9mm的绝缘直径相等的电缆接头上。进行该应用时的温度接近0℃。
在这些应用条件(由于套管材料的弹性性能，该条件特别恶劣)下，在移走管状支撑件几分钟后对该套管施加0.5MPa的压力。在应用套管20分钟后对接头作电试验，证明其功能完好。
上述尺寸的确定是基于以下事实：以所用材料，可以知道，为了确保在组装时在最小的电缆的绝缘体上具有良好的压力(至少0.1MPa-0.2MPa)，在静止的套管的内径以及对其施加压力的电缆的绝缘体之间必须提供约35％-40％的标准负性公差。
在这种情况下，用于具有50mm2的横截面积的电缆的套管具有与40％的标准负性公差相应的19.9mm/1.4mm=14mm的内径。
就由均质聚合物材料制成的通用支撑件来说，,为了采用单套管来包覆电缆的整个范围，必须具有这样的支撑件，该支撑件具有大于44.5mm的内径，外加由带子的自由端占据的空间以便在实现导体的连接之前能把在该支撑件上扩展的套管定位在电缆外皮上。实际上该支撑件至少应有50mm的内径。
50mm的内径将意味着至少56mm的外径(支撑壁的厚度约为3mm，足以经受住施加到套管上的外压力)。
如果具有14mm的内径的套管装配在具有56mm的外径的一支撑件上，它不得不扩展300％。
实验表明，实际上不可能施加这样的高扩展，并且同时即使在应用于最小的横截面积的情况下或者特别是在长期存储并以低的温度例如0℃-5℃进行铺设之后，在几分钟之内确保良好的弹性回复以便施加足够的压力。
由本申请人所作出的实验表明为了达到令人满意的结果，必须考虑到用于形成不同套管层的化合物的扩展性以及这些化合物的弹性回复能力。
特别是，在导致本发明产生的实验期间，已观察到用以上所述的具有95％-100％的网状结构程度的材料制成的并且受到300％扩展的套管在最里面的、场控制层出现撕裂它在存储模拟期间所受应力最大。
某些套管仅用具有最大扩展性的并且采用相同材料而保持较低即从60％到70％的网状结构程度的最内层来制成。这些套管在存储模拟期间(65℃下6周)没有出现撕裂。
然后，在与上述相同的铺设条件下，在温度约为0℃时，把这些套管应用到上述电缆的接头上。
在这些条件下，当铺设时套管不会对电缆绝缘体施加合格的压力，并在其上滑动，这种不足压力的条件在应用后要持续几分钟(10-20分钟)。
所以，就用本材料制成的套管来说，为了保证弹性回复和材料的强度，它的合格的扩展就应当约为200％-250％，而更高的扩展不会给出可令人接受的结果。
在这种情况下，就公知的支撑件来讲，必须采用至少两种不同的套管尺寸，以便包覆所给出的电缆范围。例如，在具有外径为46mm的支撑件上扩展的内径为14mm的套管用于50-95mm2的导体横截面积，而在具有56mm的外径的支撑件上扩展的内径为17mm的另一套管用于95-240mm2的导体横截面积。
相反，就根据本发明的支撑件来说，其中它包括具有高弹性模量和高结构强度并形成连续螺纹的一部分以及由被设计成使螺旋的各圈以可撕裂的方式被约束的低强度材料制成的一部分，能够为具有薄壁的支撑件设定尺寸，而不会危及结构强度，因此，允许限制施加到要装配在支撑件上的套管的扩展性，以便能够采用单套管来包覆50-240mm2的所有横截面积，且该套管不会经受过度的扩展量。
