380V選用MYH12-750V壓敏電阻；較大容量的電機(jī)變壓器應(yīng)選用MYH20或MYH2024通流容量大的壓敏電阻。選用原則是220V選用500V-600V壓敏電阻，380V時(shí)可選用800V-900V壓敏電阻。調(diào)壓應(yīng)用SSR，TSR調(diào)壓型模塊，可采用外配模擬量信號(hào)來觸發(fā)模塊就可實(shí)現(xiàn)線性可調(diào)輸出電壓。例如，PLC或控溫儀輸出模擬量信號(hào)：1-5V，4-20mA的觸發(fā)系統(tǒng)。國產(chǎn)單相三相可控硅觸發(fā)板，配合可控硅，也可以外配模擬量信號(hào)來調(diào)節(jié)觸發(fā)板，觸發(fā)板再觸發(fā)模塊就可實(shí)現(xiàn)線性可調(diào)輸出電壓，控制可控硅導(dǎo)通角，以達(dá)到調(diào)壓之目的。交流調(diào)功“交流調(diào)功”是一種Z型SSR普遍采用的方法，也能實(shí)現(xiàn)PID調(diào)節(jié)。即在固定周期內(nèi)，淄博單相整流橋模塊，控制交流正弦電流半波個(gè)數(shù)，達(dá)到調(diào)功目的。模擬電路常采用電壓比較器，將一個(gè)固定周期的鋸齒電壓和來自前級(jí)誤差電壓作比較，輸出方波實(shí)現(xiàn)調(diào)節(jié)，如圖3所示。在計(jì)算機(jī)上采用計(jì)時(shí)算法，產(chǎn)生占空比可調(diào)的方波脈沖擊來實(shí)現(xiàn)。例如日本的SHIMADEW和OMRON公司的SR22、FD20、E5系列智能化控溫產(chǎn)品，配合Z型SSR，實(shí)現(xiàn)自適應(yīng)“自動(dòng)翻轉(zhuǎn)”控制，即通過計(jì)算機(jī)產(chǎn)生擾動(dòng)，算出佳PID控制參數(shù)，淄博單相整流橋模塊。三相電流HS系列SSR產(chǎn)品，可直接用于三相電機(jī)的控制。簡(jiǎn)單的方法，淄博單相整流橋模塊，是采用2只SSR作電機(jī)通斷控制，4只SSR作電機(jī)換相控制。淄博正高電氣深受各界客戶好評(píng)及厚愛。淄博單相整流橋模塊</p><div

限流電阻可接在R1-R4位置，當(dāng)兩線間任意兩個(gè)繼電器接錯(cuò)時(shí)，可限制半周線間的短路電流，使其不超過繼電器所能承受的浪涌電流，避免燒毀繼電器，保證安全，但副作用是電阻器在正常工作時(shí)會(huì)產(chǎn)生電壓降和功耗。為保證使用安全，回路中的繼電器應(yīng)選用閉鎖電壓大于600V、額定電壓大于380V的交流固態(tài)繼電器。固態(tài)繼電器控制電機(jī)正反向電路，帶固態(tài)繼電器的三相電動(dòng)機(jī)的正向和反向電路如圖3-31所示。圖3-31帶固態(tài)繼電器的三相電機(jī)正反向電路當(dāng)開關(guān)S設(shè)置為“1”時(shí)，電機(jī)向前旋轉(zhuǎn)，當(dāng)開關(guān)S設(shè)置為“3”時(shí)，電機(jī)反轉(zhuǎn)。當(dāng)采用邏輯電路進(jìn)行控制時(shí)，需要增加一個(gè)延時(shí)電路，使電機(jī)在正反向轉(zhuǎn)換時(shí)延時(shí)大于50ms。在自動(dòng)控制中，為了使被控對(duì)象在一定的時(shí)間內(nèi)工作或使下一個(gè)操作指令在適當(dāng)?shù)臅r(shí)間發(fā)出，通常采用繼電器延時(shí)電路。圖3-32（a）所示的回路是一個(gè)緩慢移動(dòng)的吸入回路。在電路通斷的情況下，利用RC元件的充放電功能，實(shí)現(xiàn)吸放延時(shí)。該電路主要用于需要短延時(shí)吸力的場(chǎng)合。有時(shí)，根據(jù)控制需要，只要求繼電器緩慢釋放，不允許緩慢閉合。在這種情況下，可以使用圖3-32（b）所示的電路。當(dāng)電源剛剛接通時(shí)，由于觸點(diǎn)k-1處于動(dòng)態(tài)閉合狀態(tài)，RC延時(shí)電路對(duì)閉合時(shí)間不會(huì)產(chǎn)生延時(shí)影響。</p><p>
