電流I2l的方向從T2流向T1。由特性曲線可知，這時雙向可控硅觸發(fā)導(dǎo)通規(guī)律是按象限的特性進(jìn)行的，又因為觸發(fā)是正向的，所以把這種觸發(fā)叫做“象限的正向觸發(fā)”或稱為I+觸發(fā)。(2)如果主電極T2仍加正向電壓，而把觸發(fā)改為反向(圖5b)，這時雙向可控硅觸發(fā)導(dǎo)通后，通態(tài)電流的方向仍然是從T2到T1。我們把這種觸發(fā)叫做“象限的負(fù)觸發(fā)”或稱為I-觸發(fā)。(3)兩個主電極加上反向電壓U12(圖5c)，輸入正向觸發(fā)，雙向可控硅導(dǎo)通后，通態(tài)電流從T1流向T2。雙向可控硅按第三象限特性曲線工作，因此把這種觸發(fā)叫做Ⅲ+觸發(fā)。(4)兩個主電極仍然加反向電壓U12，輸入的是反向觸發(fā)(圖5d)。

故在電路中起著自動調(diào)節(jié)、保護、轉(zhuǎn)換電路等作用。主要用于發(fā)電機、變壓器和輸電線的繼電保護裝置中，作為過電壓保護或低電壓閉鎖的啟動原件。[1]中文名電壓繼電器外文名Voltagerelay類別電氣設(shè)備學(xué)科電工學(xué)作用自動調(diào)節(jié)、保護、轉(zhuǎn)換電路分類過電壓繼電器、欠電壓繼電器目錄1介紹2分類3電磁式電壓繼電器4靜態(tài)電壓繼電器介紹編輯電壓繼電器是輸入量、特性量為電壓的量度繼電器，分為過電壓繼電器和欠電壓繼電器。前者由于電壓值達(dá)到整定值而，然后處于動后狀態(tài)；后者由于電壓值達(dá)到整定值而，然后處于釋放狀態(tài)。電壓繼電器有電磁型、晶體管型。電磁型電壓繼電器原理及結(jié)構(gòu)如圖1所示，當(dāng)電壓達(dá)到整定值時，鐵芯將舌片吸合。像德國進(jìn)口的機床，折彎機，激光焊接機等等，當(dāng)然直線軸承和直線軸是配套用的。像直線導(dǎo)軌主要是用在精度要求比較高的機械結(jié)構(gòu)上，直線導(dǎo)軌的元件和固定元件之間不用中間介質(zhì)，而用鋼球。直線導(dǎo)軌（linearslider）可分為：滾輪直線導(dǎo)軌，圓柱直線導(dǎo)軌，滾珠直線導(dǎo)軌，三種，是用來支撐和引導(dǎo)運動部件，按給定的方向做往復(fù)直線運動。依擦性質(zhì)而定，直線運動導(dǎo)軌可以分為導(dǎo)軌、導(dǎo)軌、彈性導(dǎo)軌、流體導(dǎo)軌等種類。中文名直線導(dǎo)軌外文名linearslider分類滾輪，圓柱，滾珠直線導(dǎo)軌作用運動部件按給定的方向做運動目錄1定義2分類3作用4自動調(diào)心能力5工作原理6應(yīng)用領(lǐng)域7使用注意8清潔導(dǎo)軌9發(fā)展概況定義編輯直線導(dǎo)軌又稱線軌、滑軌、線性導(dǎo)軌、線性滑軌。
