技術(shù)指標(biāo)直流電源的技術(shù)指標(biāo)分為兩種：一種是特性指標(biāo)，包括允許輸入電壓、輸出電壓、輸出電流及輸出電壓調(diào)節(jié)范圍等；另一種是質(zhì)量指標(biāo)，用來衡量輸出直流電壓的穩(wěn)定程度，包括穩(wěn)壓系數(shù)(或電壓調(diào)整率)、輸出電阻(或電流調(diào)整率)、紋波電壓(周圍與隨機漂移)。 </p> <p> 1) 穩(wěn)壓系數(shù)及電壓調(diào)整率穩(wěn)壓系數(shù)是指在負(fù)載電流、環(huán)境溫度不變的情況下，輸入電壓的相對變化引起輸出電壓的相對變化。電壓調(diào)整率是指輸入電壓相對變化為±10%時的輸出電壓相對變化量，穩(wěn)壓系數(shù)和電壓調(diào)整率均說明輸入電壓變化對輸出電壓的影響，因此只需測試其中之一即可。 </p> <p> <br /> </p> <p> 2) 輸出電阻及電流調(diào)整率輸出電阻與放大器的輸出電阻相同，其值為當(dāng)輸入電壓不變時，輸出電壓變化量與輸出電流變化量之比的***值。電流調(diào)整率：輸出電流從0變到最大值時所產(chǎn)生的輸出電壓相對變化值。輸出電阻和電流調(diào)整率均說明負(fù)載電流變化對輸出電壓的影響，因此也只需測試其中之一即可。 </p> <p> <br /> </p> <p> 3)紋波電壓疊加在輸出電壓上的交流電壓分量。用示波器觀測其峰峰值一般為毫伏量級。也可用交流毫伏表測量其有效值，河南是德直流電源可編程，河南是德直流電源可編程，但因紋波不是正弦波，所以有一定的誤差，河南是德直流電源可編程，一般直流電源的紋波電壓VP-P≤10mV。 </p> <p> <br />

可編程直流電源，在航天航空領(lǐng)域主要用于DC-DC電源模塊、蓄電池、飛行模擬器等直流用電設(shè)備的測試?？煽啃詼y試用電設(shè)備的可靠性測試通常包括電壓跌落測試、溫升測試、ON/OFF測試、老化測試等。而對于航天航空用電設(shè)備來說，要進行比常規(guī)更為嚴(yán)苛的測試，要求用電設(shè)備不*能在正常供電情況下穩(wěn)定工作，還要能應(yīng)付供電異常的狀況。 </p> <p> <br /> </p> <p> 例如：在飛機上，供電系統(tǒng)給各種各樣的直流用電設(shè)備供電，而飛機上的供電系統(tǒng)有時會存在過壓或欠壓的狀況，保證用電設(shè)備在這些異常情況下正常工作，就是對飛機功能性以及安全性的保證。因此，過欠壓測試必不可少。直流電源在該測試中用以模擬供電系統(tǒng)，通過輸出一個連續(xù)的電壓變化波形來模擬飛機供電系統(tǒng)的電壓變化，對用電設(shè)備進行供電，測試用電設(shè)備是否會在過壓、欠壓、正常電壓這三種不同的電壓狀態(tài)下都能保持正常工作。圖1是在對飛機上的用電設(shè)備做過欠壓測試時利用直流電源模擬飛機供電系統(tǒng)輸出的電壓波形：江西艾德克斯直流電源哪個品牌好雙路輸出可調(diào)直流電源。</p><div

style="text-indent:25px">水冷電纜：水冷電纜的作用是連接中頻電源和感應(yīng)線圈，它是用每根直徑Φ0.6–Ф0.8紫銅線絞合而成。對于500公斤電爐，電纜截面積為480平方毫米，對于250公斤電爐，電纜截面積采用300至400平方毫米。水冷電纜外膠管采用耐壓5公斤的壓力橡膠管，里面通以冷卻水，它是負(fù)載回路的一部分，工作時受到拉力和扭力，與爐體一起傾動而發(fā)生曲折，因此時間長后容易在柔性連接處斷裂開。水冷電纜斷裂過程，一般是先斷掉大部分后，在大功率運行時把未斷小部分很快燒斷，這時中頻電源就會產(chǎn)生很高的過電壓，如果過電壓保護不可靠，就會燒壞晶閘管。水冷電纜斷開后，中頻電源無法啟動工作。如不檢查出原因而反復(fù)啟動，就很可能燒壞中頻電壓互感器。檢查故障時可用示波器，把示波器探頭夾在負(fù)載兩端，觀察按啟動按鈕時有無衰減波形。確定電纜斷芯時先把水冷電纜與電熱電容器輸出銅排脫開，用萬用表電阻擋（200Ω擋）測量電纜的電阻值，正常時電阻值為零，斷開時為無窮大。用萬用表測量時，應(yīng)把爐體翻到傾倒位置，使水冷電纜掉起，這樣使斷處徹底脫離，才能正確判斷是否斷芯。</p><p

style="text-indent:25px">直流穩(wěn)壓電源可以分類兩類，包括線性和開關(guān)型。線性線性穩(wěn)定電源有一個共同的特點就是它的功率器件調(diào)整管工作在線性區(qū)，靠調(diào)整管之間的電壓降來穩(wěn)定輸出。由于調(diào)整管靜態(tài)損耗大，需要安裝一個很大的散熱器給它散熱。而且由于變壓器工作在工頻（50Hz)上，所以重量較大。該類電源優(yōu)點是穩(wěn)定性高，紋波小，可靠性高，易做成多路，輸出連續(xù)可調(diào)的成品。缺點是體積大、較笨重、效率相對較低。這類穩(wěn)定電源又有很多種，從輸出性質(zhì)可分為穩(wěn)壓電源和穩(wěn)流電源及集穩(wěn)壓、穩(wěn)流于一身的穩(wěn)壓穩(wěn)流（雙穩(wěn)）電源。從輸出值來看可分定點輸出電源、波段開關(guān)調(diào)整式和電位器連續(xù)可調(diào)式幾種。從輸出指示上可分指針指示型和數(shù)字顯示式型等等。河南是德直流電源可編程</p><p
