绝缘管型母线的行业现状分析及关键技术展望

Industry Status Analysis and Key Technology Expectation for Insulated Tubular Busbar

绝缘管型母线作为一种新型的低压侧电流输送设备,以其独特优势使其近年来的使用量迅猛增长,但该类设备应用中频繁发生的故障及其造成的不良后果严重制约了进一步推广。通过对绝缘管型母线生产厂家、应用方及相关文献的广泛调研,总结了该类设备行业现状、设备技术特点,分析了应用中出现的典型故障,归纳了该类设备生产、应用环节存在的共性问题,并据此展望解决上述问题所需开展研究的关键技术。绝缘管型母线的特性适用于各用电行业对低压侧电流输送大容量、高安全性和灵活性的需求;中国的该类设备的生产、应用和研究尚属起步阶段,运行中的常见故障暴露出行业对绝缘管型母线的设计、生产、安装、运行和全过程检测等方面均存在不足,必须从技术水平和管理制度上寻求优化产品和提高产品运行可靠性的方法。

As a new type of current-conveying equipment at low voltage side, insulated tubular busbar has been increasing rapidly in recent years for its unique advantages. However, the frequent failures and adverse consequences in the application of this kind of equipment have seriously restricted its further extension. Based on extensive investigation of the manufacturers, applications and related documents of insulated tubular busbar, this paper summarizes the industry status and the technological characteristics of this equipment, analyzes the typical failure in the application, sums up the common problems in the production and application of this kind of equipment, and proposes the key technologies which should be researched in the future to solve the above problems. This article proposes that, the characteristics of the insulated tubular busbar exactly meets the needs of high-capacity, high safety level and flexibility for current-carrying which are demanded by the industry customers; the manufacture ,the application of this kind of equipment and the related researches have just started in China; the common failures in the operation reveal that there are quite deficiencies in the aspects of design, manufacture, assembling, operation and test during whole processes of the insulated tubular busbar; and methods in the aspects of engineering level and management system should be developed to optimize the equipment and improve its operating reliability.
