【摘要】：自古至今,衡量生产水平的两大指标一直是质量和效率。测试对于保证质量的重要性是不言而喻的,没有测试就无法评定产品质量的优劣。生产效率同样也离不开测试,为了提高生产效率必须实现自动化测试,并且进一步发展实现智能化检测。剩余电流互感器是专用于检测剩余电流的互感器,也是剩余电流保护断路器的核心部件。随着配电市场对剩余电流保护断路器的需求越来越大,意味着需要生产、检测的剩余电流互感器的数量也就越来越多,而传统的人工检测方式已明显制约了剩余电流保护断路器的产能需求。因此,需要研究智能检测技术实现对剩余电流互感器的自动化测试,减少人为的参与,提高检测效率。本文首先仔细介绍了剩余电流互感器的工作原理、剩余电流波形的特点与类型,确定了剩余电流互感器需要检测的要素,提出了自动检测装置及系统的设计原理,研究了实现检测装置及系统的关键技术,并通过对微控制器(Micro Controller Unit,简称MCU)技术和上位机软件编程技术的应用分析,确定采用以C8051F020作为自动检测装置的核心,以可视化编程语言Visual Basic 6.0(简称VB6.0)进行上位机软件开发。其次,基于上述微控制器组建了装置的硬件平台,以VB6.0完成了上位机软件编程,通过两者联调与反复试验研究,完成了一种剩余电流互感器自动检测装置及系统的设计,可以实现对剩余电流互感器主要特性的自动化检测。本文设计的剩余电流互感器自动检测装置及系统表明了微控制器和Visual Basic 6.0技术较适合于剩余电流互感器的自动化测试,提高了剩余电流互感器的检测效率。并且,此次设计过程为以后开发出更复杂更高效的其它检测装置奠定了基础。最后,将研制的样机应用于实际的检测工作,并通过与传统的检测方式对比,表明该装置及系统具有较好的检测效率,一定程度上也提高了剩余电流保护断路器整机的质量水平,满足了该类产品产能的需求。
[Abstract]:Since ancient times, the two indicators to measure the level of production have been quality and efficiency. The importance of testing to ensure quality is self-evident. Without testing, it is impossible to evaluate the quality of the product. Production efficiency is also inseparable from testing. In order to improve production efficiency, automatic testing must be realized, and intelligent testing must be further developed. Residual current transformer (RCT) is used to detect residual current and is also the core component of residual current protection circuit breaker. With the increasing demand for residual current protection circuit breakers in the distribution market, it means that more and more residual current transformers need to be produced, and the number of residual current transformers detected will also be more and more. The traditional manual detection method has obviously restricted the capacity demand of residual current protection circuit breakers. Therefore, it is necessary to study intelligent detection technology to realize automatic testing of residual current transformer, reduce artificial participation and improve detection efficiency. In this paper, the working principle of the residual current transformer, the characteristics and types of the residual current waveform are introduced carefully, the essential elements of the residual current transformer need to be tested are determined, and the design principle of the automatic detecting device and system is put forward. The key technology of realizing the detection device and the system is studied. Through the analysis of the application of the microcontroller (Micro Controller Unit, (MCU) technology and the software programming technology of the upper computer, it is decided to adopt C8051F020 as the core of the automatic detection device. The software of upper computer is developed by visual programming language Visual Basic 6.0( abbreviated as VB6.0). Secondly, the hardware platform of the device is set up based on the above-mentioned micro-controller, and the software programming of the upper computer is completed with VB6.0. The design of an automatic detecting device and the system of residual current transformer is completed through the combination of the two and the repeated experimental research. Automatic detection of main characteristics of residual current transformer can be realized. The automatic detecting device and system of residual current transformer designed in this paper show that microcontroller and Visual Basic 6.0technology are more suitable for automatic testing of residual current transformer, and improve the detecting efficiency of residual current transformer. In addition, the design process lays a foundation for the development of more complex and more efficient detection devices in the future. Finally, the prototype is applied to the actual detection work, and through the comparison with the traditional detection method, it is shown that the device and the system have a better detection efficiency. To a certain extent, the quality level of the residual current protection circuit breaker is improved and the production capacity of this kind of circuit breaker is satisfied.
