??????? UV固化設備電(dian)路主要包括電(dian)源變壓器(qi)、溫度控(kong)制(zhi)、漏電(dian)保護、散熱、與印刷機聯機控(kong)制(zhi)、功(gong)率控(kong)制(zhi)、伺服控(kong)制(zhi)、電(dian)機速度控(kong)制(zhi)等系(xi)統(tong)。

??????? UV固化設備電路的特點是髙功率、高電壓，因此心臟器件是髙功率的，通常用漏磁變壓器。UV燈是(shi)高溫器件，點燃時表面溫度高達500-700°C，溫度控制和(he)散熱(re)系統(tong)十(shi)分關鍵(jian)，溫度控制器與散熱(re)風機或水冷系統(tong)聯動控制是(shi)關鍵(jian)控制。

??????? 高壓高功(gong)率電(dian)(dian)路的(de)(de)漏電(dian)(dian)保(bao)護系(xi)統(tong)關系(xi)到從業(ye)人員的(de)(de)生命安全。下面介紹UV燈(deng)電(dian)(dian)源(yuan)(yuan)的(de)(de)基本(ben)(ben)電(dian)(dian)路。 UV燈(deng)電(dian)(dian)源(yuan)(yuan)的(de)(de)基本(ben)(ben)電(dian)(dian)路如圖1所示。 UV燈(deng)電(dian)(dian)源(yuan)(yuan)的(de)(de)基本(ben)(ben)電(dian)(dian)路 圖1 UV燈(deng)電(dian)(dian)源(yuan)(yuan)的(de)(de)基本(ben)(ben)電(dian)(dian)路 它包(bao)括漏磁(ci)變(bian)(bian)(bian)(bian)壓器(qi)(qi)(qi)(qi)、熔斷器(qi)(qi)(qi)(qi)FU及熱繼電(dian)(dian)器(qi)(qi)(qi)(qi)FR，分(fen)別作(zuo)短路和過載保(bao)護；接(jie)觸器(qi)(qi)(qi)(qi)KM線圈本(ben)(ben)身又可作(zuo)失壓保(bao)護；在變(bian)(bian)(bian)(bian)壓器(qi)(qi)(qi)(qi)次(ci)級(ji)串接(jie)電(dian)(dian)容，利用交流阻抗對電(dian)(dian)路起限壓限流的(de)(de)作(zuo)用，通過改(gai)變(bian)(bian)(bian)(bian)電(dian)(dian)容值改(gai)變(bian)(bian)(bian)(bian)燈(deng)管功(gong)率，同(tong)時(shi)對變(bian)(bian)(bian)(bian)壓器(qi)(qi)(qi)(qi)及UV燈(deng)管都可保(bao)護。

工作過程是，閉合空氣開關Q，按啟動按鈕SBst，接觸器線圈KM通電，主觸點閉合，動合輔助觸點閉合實現自鎖，電壓通過變壓器升成高壓后點亮燈管，按下SBstp停止按鈕，即斷開接觸器線圈電源，使電路停止工作。保定市弘益機械設備制造有限公司。
