摘 要：交流接觸器是電力系統(tǒng)和自動(dòng)化控制系統(tǒng)中不可缺少的量大面廣的低壓電器。但是傳統(tǒng)接觸器功能單一、耗電多、噪音大、觸頭容易燒毀、壽命短。隨著科學(xué)技術(shù)的飛速發(fā)展，電力網(wǎng)和其他控制系統(tǒng)和保護(hù)電路對(duì)交流接觸器的性能要求日益提高，希望設(shè)計(jì)制造出體積小、重量輕、壽命高、精度和可靠性高、節(jié)能、可通信、價(jià)格合理的交流接觸器。本課題的研究具重要的經(jīng)濟(jì)意義和社會(huì)的應(yīng)用價(jià)值。本文主要介紹了智能接觸器數(shù)據(jù)采集模塊的設(shè)計(jì)，開(kāi)關(guān)量、模擬量信號(hào)的采集. Abstract：AC contactor is widely used in power system and automatic control system. But unfortunately, traditional contactors consume too much energy, make big noises and have short lives. And usually a contactor just has one single function.With the development of science, high requests are brought forward in power system and control systems. Contactors with higher performances are needed, including smaller dimensions, lighter weights, higher precision, higher reliabilities and communication services. This research has significant economic and social importance. This paper is about data collection modular of intelligent AC contactor. 關(guān)鍵詞：智能接觸器;數(shù)據(jù)采集;傳感器 Keywords：intelligent AC contactor; data collection; sensor 1.前言 　　電器智能化是現(xiàn)代科學(xué)技術(shù)與傳統(tǒng)電器技術(shù)相結(jié)合的產(chǎn)物。它融合了傳統(tǒng)電器、計(jì)算機(jī)與數(shù)字控制、微電子技術(shù)、電力電子技術(shù)、計(jì)算機(jī)通信與網(wǎng)絡(luò)及現(xiàn)代傳感器技術(shù)等各門(mén)類的學(xué)科。智能電器具有自動(dòng)監(jiān)控和識(shí)別故障類型及操作命令類型的功能，能根據(jù)故障和操作命令類別來(lái)控制電器元件操作機(jī)構(gòu)動(dòng)作。對(duì)現(xiàn)場(chǎng)參量精確、快速的采集是智能電器做出正確判斷的基礎(chǔ)。但是一般情況下，現(xiàn)場(chǎng)參量是高電壓、大電流的參數(shù)。對(duì)于5V或是3.3V的控制系統(tǒng)來(lái)說(shuō)，技術(shù)上要做處理。本文提出了對(duì)高電壓大電流的電參數(shù)的采集方法。 2.智能接觸器功能分析 　　智能接觸器的主要任務(wù)是采集三相交流電流、三相交流電壓及電機(jī)溫度，對(duì)電機(jī)進(jìn)行過(guò)載保護(hù)和欠壓、過(guò)壓、缺相等保護(hù)。智能接觸器有外接鍵盤(pán)和顯示器，并能與上位機(jī)通信。根據(jù)以上分析 ，可將設(shè)計(jì)任務(wù)分為三部分：現(xiàn)場(chǎng)參量及檢測(cè);監(jiān)控單元的設(shè)計(jì);通信。 詳情請(qǐng)點(diǎn)擊：智能交流接觸器數(shù)據(jù)采集模塊的研究
