【摘要】：自古至今,衡量生產(chǎn)水平的兩大指標(biāo)一直是質(zhì)量和效率。測試對于保證質(zhì)量的重要性是不言而喻的,沒有測試就無法評定產(chǎn)品質(zhì)量的優(yōu)劣。生產(chǎn)效率同樣也離不開測試,為了提高生產(chǎn)效率必須實現(xiàn)自動化測試,并且進一步發(fā)展實現(xiàn)智能化檢測。剩余電流互感器是專用于檢測剩余電流的互感器,也是剩余電流保護斷路器的核心部件。隨著配電市場對剩余電流保護斷路器的需求越來越大,意味著需要生產(chǎn)、檢測的剩余電流互感器的數(shù)量也就越來越多,而傳統(tǒng)的人工檢測方式已明顯制約了剩余電流保護斷路器的產(chǎn)能需求。因此,需要研究智能檢測技術(shù)實現(xiàn)對剩余電流互感器的自動化測試,減少人為的參與,提高檢測效率。本文首先仔細介紹了剩余電流互感器的工作原理、剩余電流波形的特點與類型,確定了剩余電流互感器需要檢測的要素,提出了自動檢測裝置及系統(tǒng)的設(shè)計原理,研究了實現(xiàn)檢測裝置及系統(tǒng)的關(guān)鍵技術(shù),并通過對微控制器(Micro Controller Unit,簡稱MCU)技術(shù)和上位機軟件編程技術(shù)的應(yīng)用分析,確定采用以C8051F020作為自動檢測裝置的核心,以可視化編程語言Visual Basic 6.0(簡稱VB6.0)進行上位機軟件開發(fā)。其次,基于上述微控制器組建了裝置的硬件平臺,以VB6.0完成了上位機軟件編程,通過兩者聯(lián)調(diào)與反復(fù)試驗研究,完成了一種剩余電流互感器自動檢測裝置及系統(tǒng)的設(shè)計,可以實現(xiàn)對剩余電流互感器主要特性的自動化檢測。本文設(shè)計的剩余電流互感器自動檢測裝置及系統(tǒng)表明了微控制器和Visual Basic 6.0技術(shù)較適合于剩余電流互感器的自動化測試,提高了剩余電流互感器的檢測效率。并且,此次設(shè)計過程為以后開發(fā)出更復(fù)雜更高效的其它檢測裝置奠定了基礎(chǔ)。最后,將研制的樣機應(yīng)用于實際的檢測工作,并通過與傳統(tǒng)的檢測方式對比,表明該裝置及系統(tǒng)具有較好的檢測效率,一定程度上也提高了剩余電流保護斷路器整機的質(zhì)量水平,滿足了該類產(chǎn)品產(chǎn)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.
