[摘 要]传统方式的SF6钢瓶搬运一般采用人工滚动方式,或采用轮式机械车拖运,不仅效率低,操作不当还容易造成人体受伤。本文研制一种基于强磁吸技术的钢瓶自动搬运车,由大容量电池提供大电流产生强磁场,完成对钢瓶的吸取,到达目标位置再解磁落放,实现了人体与钢瓶免接触,避免了工伤事故,提高了工作效率。本搬运车还设计了自动称重系统,可以自动计算钢瓶中SF6余量,并将计算结果通过无线传输技术远传至数据中心,实现SF6余量自动化管理。

[Abstract]The traditional way of SF6 cylinder transportation is generally manual rolling or wheeled mechanical truck hauling, which is not only low in efficiency, but also easy to cause human injury due to improper operation. This article develops a steel cylinder automatic transport vehicle based on strong magnetic attraction technology. The large-capacity battery provides a large current to generate a strong magnetic field, completes the absorption of the steel cylinder, and then demagnetizes it when it reaches the target position. It reduces work accidents and improves work efficiency. The truck is also designed with an automatic weighing system, which can automatically calculate the SF6 margin in the cylinder, and transmit the calculation result to the data center through wireless transmission technology to realize the automatic management of SF6 margin.

SF6气体作为绝缘和灭弧的介质广泛应用于电气设备中。SF6新气或回收的废旧SF6气体一般以液態形式存储在高压钢瓶中。SF6气体绝缘电气设备的运维检修过程及运维检修仪器的实验室校验过程中都存在大量的钢瓶搬运工作。传统方式的SF6钢瓶搬运一般采用人工滚动方式,不仅效率低,操作不当还容易造成人体受伤。故,亟须研究一种高效、安全的SF6钢瓶自动搬运车,在人体与钢瓶无接触的情况下实现钢瓶的自动搬运。可以考虑采用磁吸技术来实现钢瓶的搬运。
1 磁吸技术
1.1 磁吸技术的原理
磁吸技术是基于电磁铁的励磁和解磁进行操作的。在铁芯的外部缠绕与其功率相匹配的导电绕组。直流电源为电磁铁输入直流电,铁芯被导电绕组的磁场磁化,磁化后的铁芯也变成了一个磁体,两个磁场互相叠加使得导电绕组的磁性增强。……
