技术领域 technical field
本发明涉及高压电气领域，特别是涉及到一种可用于高压直流输电的空心复合绝缘子及其连接法兰。 The invention relates to the high-voltage electrical field, in particular to a hollow composite insulator and a connecting flange that can be used for high-voltage direct current transmission.
背景技术 Background technique
在高压输电设备中，空心复合绝缘子是一种及其普遍的部件。目前的空心复合绝缘子均是由筒形的绝缘套筒和与绝缘套筒固定装配在一起的连接法兰组成，连接法兰包括法兰盘和位于法兰盘一侧的法兰轴，其中连接法兰与绝缘套筒之间便是通过其法兰轴固定在一起的。法兰轴伸入至绝缘套筒的一端，其与绝缘套筒之间的固定方式有粘接、螺纹连接、嵌接等几种。 In high-voltage power transmission equipment, hollow composite insulators are an extremely common component. The current hollow composite insulators are composed of a cylindrical insulating sleeve and a connecting flange fixedly assembled with the insulating sleeve. The connecting flange includes a flange plate and a flange shaft located on one side of the flange plate. The flange and the insulating sleeve are fixed together by the flange shaft. The flange shaft extends into one end of the insulating sleeve, and the fixing methods between it and the insulating sleeve include bonding, screw connection, scarfing, etc.
在绝缘子的长度规格较小的情况下，上述法兰轴与绝缘套筒之间的连接方式均是可以满足要求的，但是，如果遇到长度较长或者重量过重的绝缘子，则绝缘套筒与连接法兰之间便会因为挠性变形等因素而使得绝缘套筒与连接法兰松动脱离，进而引起绝缘子自身力学性能或电气性能的失效。 When the length of the insulator is small, the connection between the above-mentioned flange shaft and the insulating sleeve can meet the requirements. However, if an insulator with a long length or heavy weight is encountered, the insulating sleeve Due to factors such as flexible deformation, the insulating sleeve and the connecting flange will loosen and separate from the connecting flange, which will cause the failure of the mechanical or electrical properties of the insulator itself.
总的来说，目前的空心复合绝缘子存在绝缘套筒与连接法兰连接不牢的问题。 Generally speaking, the current hollow composite insulators have the problem that the insulating sleeve and the connecting flange are not firmly connected.
发明内容 Contents of the invention
本发明的目的在于提供一种空心复合绝缘子，以解决目前的空心复合绝缘子存在的绝缘套筒与连接法兰连接不牢的问题。 The object of the present invention is to provide a hollow composite insulator to solve the problem that the insulating sleeve and the connecting flange are not firmly connected in the current hollow composite insulator.
另外，本发明的目的还在于提供上述空心复合绝缘子的连接法兰。 In addition, the purpose of the present invention is also to provide a connecting flange of the above-mentioned hollow composite insulator.
为了解决上述问题，空心复合绝缘子采用以下技术方案：空心复合绝缘子，包括绝缘套筒和连接法兰，连接法兰包括法兰轴，法兰轴的外周面上设有弹性胀紧结构，弹性胀紧结构胀紧在法兰轴与绝缘套筒之间。 In order to solve the above problems, the hollow composite insulator adopts the following technical scheme: the hollow composite insulator includes an insulating sleeve and a connecting flange, the connecting flange includes a flange shaft, and the outer peripheral surface of the flange shaft is provided with an elastic expansion structure. The tight structure is tightened between the flange shaft and the insulating sleeve.
所述弹性胀紧结构形成了法兰轴的倒刺结构。 The elastic expansion structure forms the barb structure of the flange shaft.
所述弹性胀紧结构为环形翅片。 The elastic expansion structure is an annular fin.
所述环形翅片有两个以上，各环形翅片沿法兰轴的轴向分布并且相邻两环形翅片间形成了胶槽，胶槽中填充有粘结胶。 There are more than two annular fins, and each annular fin is distributed along the axial direction of the flange shaft, and a glue groove is formed between two adjacent ring fins, and the glue groove is filled with adhesive glue.
所述弹性胀紧结构由间隔分布于法兰轴外周面上的翅片构成。 The elastic expansion structure is composed of fins distributed at intervals on the outer peripheral surface of the flange shaft.

所述弹性胀紧结构由间隔分布于法兰轴外周面上的翅片构成。 The elastic expansion structure is composed of fins distributed at intervals on the outer peripheral surface of the flange shaft.
由于该空心复合绝缘子的法兰轴的外周面上设有弹性胀紧结构，弹性胀紧结构胀紧在法兰轴与绝缘套筒之间，因此一旦法兰轴插入至绝缘套筒，则弹性胀紧结构便会被压缩，从而将连接轴和绝缘套筒牢牢的结合在一起，防止连接法兰被从绝缘套筒中抽出，进而解决了目前的空心复合绝缘子存在的绝缘套筒与连接法兰连接不牢的问题。 Since the outer peripheral surface of the flange shaft of the hollow composite insulator is provided with an elastic expansion structure, the elastic expansion structure is expanded between the flange shaft and the insulation sleeve, so once the flange shaft is inserted into the insulation sleeve, the elastic The expansion structure will be compressed, so that the connecting shaft and the insulating sleeve are firmly combined to prevent the connecting flange from being pulled out from the insulating sleeve, thereby solving the existing problem of the insulating sleeve and the connection between the current hollow composite insulators. The problem of weak flange connection.
更进一步的，倒刺结构能够起到卡住绝缘套筒的作用，进一步增加连接法兰与绝缘套筒之间结合的可靠性。 Furthermore, the barb structure can play a role in clamping the insulating sleeve, further increasing the reliability of the connection between the connecting flange and the insulating sleeve.
