由于MAX810L的復(fù)位門檻電平為4.65V,因此其RESET端輸出為高電平,迫使Q1關(guān)斷,從而使負(fù)載與輸入電源斷開。MAX668通過外部反饋電阻網(wǎng)絡(luò)設(shè)定5V輸出電壓。當(dāng)輸出電壓超MAX810L的復(fù)位門檻電平時(shí),其內(nèi)部單穩(wěn)電路開始工作并延時(shí)約240ms。之后,MAX810L的輸出變低,使Q1導(dǎo)通。Q1導(dǎo)通之后,MAX810L一直監(jiān)測(cè)輸出電壓以確定輸出是否過流。過載將會(huì)輸出電壓下降,當(dāng)它低于MAX810L門檻電平時(shí),MAX810L的輸出經(jīng)過20μs的后由高變低,從而關(guān)斷Q1并使負(fù)載斷開。由于MAX668的升壓作用,MAX810電源端電壓又會(huì)高于其門檻電平,240ms的復(fù)位時(shí)間后,MAX810L輸出再次由高變低。銅線r53m/(Ωmm2),鋁線r32m(Ωmm2),S為導(dǎo)線截面積(mm2),LC為導(dǎo)線的計(jì)算長(zhǎng)度(m)。設(shè)互感器到儀表單向長(zhǎng)度為L(zhǎng)1,則:L1互感器為星形接LCL1兩相V形接線2L1一相式接線繼電保護(hù)用的電流互感器的準(zhǔn)確度常用的有5P和l0P。保護(hù)級(jí)的準(zhǔn)確度是以額定準(zhǔn)確限值一次電流下的電流互感器電流互感器復(fù)合誤差ε%來標(biāo)稱的(如5P對(duì)應(yīng)的ε%5%)。所謂額定準(zhǔn)確限值一次電流即一次電流為額定一次電流的倍數(shù)(nI1/I1n),也稱為額定準(zhǔn)確限值系數(shù)。即要求保護(hù)用的電流互感器在可能出現(xiàn)的范圍內(nèi),其復(fù)合誤差不超過ε%值。電流互感器ε%誤差曲線校驗(yàn)步驟:⑴按照保護(hù)裝置類型計(jì)算流過電流互感器的一次電流倍數(shù)⑵根據(jù)電流互感器的型號(hào)、變比和一次電流倍數(shù)。

2、更換“三濾”:螺桿空壓機(jī)的空濾芯、油濾芯以及油分芯都屬于易損部件,因而在使用一段時(shí)間后就必須更換新的。定期更換空壓機(jī)的“三濾”,可以保證壓縮空氣的。可以調(diào)節(jié)升流器電流的調(diào)壓器,及負(fù)載。[10]注意事項(xiàng)電流互感器-使用注意事項(xiàng)電流互感器[11]運(yùn)行時(shí),副邊不允許開路。因?yàn)橐坏╅_路,原邊電流均成為勵(lì)磁電流,使磁通和副邊電壓大大超過正常值而危及人身和設(shè)備。因此,電流互感器副邊回路中不許接熔斷器,也不允許在運(yùn)行時(shí)未經(jīng)旁路就拆下電流表、繼電器等設(shè)備。電流互感器運(yùn)行時(shí),副邊不允許開路。原因如下:⒈電流互感器一次被測(cè)電流磁勢(shì)I1N1在鐵芯產(chǎn)生磁通Φ1⒉電流互感器二次測(cè)量?jī)x表電流磁勢(shì)I2N2在鐵芯產(chǎn)生磁通Φ2⒊電流互感器鐵芯合磁通:ΦΦ1+Φ2⒋因?yàn)棣?.Φ2方向相反,大小相等,互相抵消,所以Φ0⒌若二次開路,即I20,則:ΦΦ1,電流互感器鐵芯磁通很強(qiáng)。
