PLC內(nèi)部繼電器的"動(dòng)作狀態(tài)(0或1)"存放在"狀態(tài)容器[?]"(狀態(tài)存貯容器、狀態(tài)存貯單元、映像寄存器)之中,供程序調(diào)用。PLC內(nèi)部繼電器的(虛擬)線圈--表示"寫"運(yùn)算(把運(yùn)算結(jié)果寫到狀態(tài)容器中),(虛擬)常開(kāi)點(diǎn)--表示"讀"運(yùn)算(從狀態(tài)容器中讀出狀態(tài)),(虛擬)常閉點(diǎn)--表示"讀反"運(yùn)算(讀出狀態(tài)→然后取反)。
主電路是給異步電動(dòng)機(jī)提供調(diào)壓調(diào)頻電源的電力變換部分,變頻器的主電路大體上可分為兩類:電壓型是將電壓源的直流變換為交流的變頻器,直流回路的濾波是電容。電流型是將電流源的直流變換為交流的變頻器,其直流回路濾波是電感。它由三部分構(gòu)成,將工頻電源變換為直流功率的"整流器",吸收在變流器和逆變器產(chǎn)生的電壓脈動(dòng)的"平波回路",以及將直流功率變換為交流功率的"逆變器"交流接觸器按負(fù)荷種類一般分為一類、二類、三類和四類,分別記為AC1 、AC2 、AC3和AC4 。
鐵殼開(kāi)關(guān)也稱封閉式負(fù)荷開(kāi)關(guān)圖1-4是它的外形與結(jié)構(gòu)圖。它有安裝在鑄鐵或鋼板制成的外殼內(nèi)的刀式觸頭和滅弧系統(tǒng)、熔斷器以及操作機(jī)構(gòu)等組成。與閘刀開(kāi)關(guān)相比它有以下特點(diǎn):(1)觸頭設(shè)有滅弧室(罩)、電弧不會(huì)噴出,可不必顧慮會(huì)發(fā)生相間短路事故;(2)熔斷絲的分?jǐn)嗄芰Ω撸话銥?KA,高者可達(dá)50KA以上;(3)操作機(jī)構(gòu)為儲(chǔ)能合閘式的,且有機(jī)械聯(lián)鎖裝置。前者可使開(kāi)關(guān)的合閘和分閘速度與操作速度無(wú)關(guān),從而改善開(kāi)關(guān)的動(dòng)作性能和滅弧性能;后者則保證了在合閘狀態(tài)下打不開(kāi)箱蓋及箱蓋未關(guān)妥前合不上閘,提高了安全性;(4)有堅(jiān)固的封閉外殼,可保護(hù)操作人員免受電弧灼傷。

接地過(guò)電流保護(hù)。逆變器負(fù)載側(cè)接地設(shè)計(jì),為了保護(hù)逆變器,有時(shí)要有接地過(guò)電流保護(hù)功能。但為了確保人身安全,需要裝設(shè)漏電斷路器。冷卻風(fēng)機(jī)異常。有冷卻風(fēng)機(jī)的裝置,當(dāng)風(fēng)機(jī)異常時(shí)裝置內(nèi)的溫度將上升。因此采用風(fēng)機(jī)熱繼電器或器件散熱片傳感器,檢出異常后停止逆變器。
在實(shí)際設(shè)備維修中,遇到最多的是進(jìn)口變頻器。如富士、三星、ABB、AB、西門子等廠家。特別是在大、中型企業(yè)舊設(shè)備技術(shù)改造中,應(yīng)用最為廣泛。其原因是由于十多年前國(guó)內(nèi)生產(chǎn)變頻器的廠家很少,其產(chǎn)品功能簡(jiǎn)單、性能低、質(zhì)量不高。而進(jìn)口變頻器機(jī)型多、技術(shù)成熟、功能齊全、性能優(yōu)越、質(zhì)量高、耐用的特點(diǎn),并且適合不同設(shè)備拖動(dòng)需求,故占據(jù)著國(guó)內(nèi)變頻器市場(chǎng)的主要部分。
以歐姆龍推出的CX-PROGRAMMER軟件為例,在編程時(shí)它能為你提供操作數(shù)的輸入范圍,迅速搜索特殊指令。根據(jù)梯形圖自動(dòng)生成語(yǔ)句表,并指出其中的語(yǔ)法錯(cuò)誤,在調(diào)試時(shí)它通過(guò)數(shù)據(jù)線把程序快速準(zhǔn)確傳入PLC,然后監(jiān)控執(zhí)行狀態(tài),可以對(duì)各輸入輸出點(diǎn)強(qiáng)制置位/復(fù)位。還可以進(jìn)行在線編輯??傊?dāng)你熟練掌握了編程軟件的使用方法。就一定能事半功倍的完成的設(shè)計(jì)任務(wù)。
