General
XGN-12 bokosi lokhazikika la AC zitsulo-lotsekedwa switchgear (lotchedwa "switchgear"), loyenera voteji 3.6～12kV, 50Hz, 630A～3150A magawo atatu AC basi imodzi, mabasi awiri, basi imodzi yodutsa system , Amagwiritsidwa ntchito polandira ndi kugawa mphamvu zamagetsi. Itha kukwaniritsa zofunikira zamitundu yosiyanasiyana yamagetsi, ma substations (ma substations) ndi mabizinesi amakampani ndi migodi.
Izi zikugwirizana ndi mfundo za dziko GB3906 "Alternating-current zitsulo-otsekeredwa switchgear ndi controlgear oveteredwa voteji pamwamba 3.6kV ndi mpaka ndi kuphatikizapo 40.5kV", IEC60298 "AC zitsulo-otsekeredwa switchgear ndi controlgear oveteredwa voteji pamwamba 1 kV ndi mmwamba mpaka ndi kuphatikiza 52kV", ndi DL/T402, DL/T404 miyezo, ndipo amakwaniritsa "zisanu kupewa" zofunika interlocking.
Kagwiritsidwe Ntchito Bwinobwino
● Kutentha kwa mpweya wozungulira: -15℃~+40℃.
● Chinyezi:
Chinyezi chapakati pa tsiku ndi tsiku: ≤95%, kuthamanga kwa mpweya wamadzi tsiku lililonse ≤2.2kPa.
Chinyezi chapakati pamwezi ndi 90%, ndipo mphamvu ya mwezi uliwonse ya nthunzi yamadzi ndi 1.8kPa.
● Kutalika: ≤4000m.
● Kuchuluka kwa chivomezi: ≤8 madigiri.
● Mpweya wozungulira sayenera kuipitsidwa ndi mpweya woyaka kapena woyaka, mpweya wamadzi, ndi zina zotero.
● Malo osagwedezeka kwambiri.
● ngati mikhalidwe yogwiritsira ntchito ikuposa zomwe zanenedwa ndi GB3906, wogwiritsa ntchito ndi wopanga adzakambirana.

Kapangidwe
● XGN-12 switch cabinet ndi zitsulo zotsekedwa bokosi. Chimango cha nduna chimawotchedwa ndi zitsulo za ngodya. Kabati imagawidwa m'chipinda chophwanyira dera, chipinda cha basi, chipinda cha chingwe, chipinda cholumikizira, ndi zina zotero, cholekanitsidwa ndi mbale zachitsulo.
● Chipinda chophwanyira dera chili m'munsi mwa kabati. Kuzungulira kwa wophwanya dera kumalumikizidwa ndi makina ogwiritsira ntchito ndi ndodo ya tayi. Malo opangira mawaya apamwamba a dera lophwanyidwa amagwirizanitsidwa ndi cholumikizira chapamwamba, cholumikizira cham'munsi cha cholumikizira chamagetsi chimalumikizidwa ndi thiransifoma yamakono, ndipo chosinthira chapano chimalumikizidwa ndi cholumikizira cholumikizira chapansi. Ndipo chipinda chophwanyira dera chilinso ndi njira yotulutsira zokakamiza. Ngati arc yamkati imachitika, mpweya ukhoza kumasula kupanikizika kudzera mu njira yotulutsa mpweya.
● Chipinda cha basi chili kumtunda chakumbuyo kwa kabati. Pofuna kuchepetsa kutalika kwa nduna, mabasiwo amapangidwa mu mawonekedwe a "pini", mothandizidwa ndi 7350N kupinda mphamvu zopangira zadothi zadothi, ndipo mabasi amalumikizidwa ndi cholumikizira chapamwamba, amatha kulumikizidwa pakati pa mabasi awiri oyandikana nawo.
● Chipinda cha chingwe chili kumbuyo kwa pansi pa kabati. Insulator yothandizira mu chipinda cha chingwe imatha kukhala ndi zida zowunikira ma voltage, ndipo zingwe zimakhazikika pa bulaketi. Pa pulani yayikulu yolumikizira, chipinda chino ndi chipinda cholumikizira chingwe. Chipinda cha relay chili kutsogolo kwa gawo lapamwamba la kabati. Bokosi loyika m'nyumba likhoza kukhazikitsidwa ndi ma relay osiyanasiyana. M'chipindacho muli mabakiti otsekera. Khomo likhoza kukhazikitsidwa ndi zigawo zachiwiri monga zida zowonetsera ndi zizindikiro za zizindikiro. Pamwambapa mutha kukhalanso ndi basi yachiwiri yaying'ono.
● Njira yogwiritsira ntchito makina oyendetsa dera imayikidwa kumbali yakumanzere ya kutsogolo, ndipo pamwamba pake pali njira yogwiritsira ntchito ndi yolumikizirana ya disconnector. switchgear ndikukonza mbali ziwiri. Zigawo zachiwiri za chipinda cha relay, njira yoyendetsera ntchito yokonza, makina olumikizirana ndi kutumizirana, ndi ophwanya dera amafufuzidwa ndikukonzedwa kutsogolo. Mabasi akuluakulu ndi ma terminals amakonzedwa kumbuyo, ndipo magetsi amaikidwa m'chipinda chophwanyira dera. Pansi pa chitseko chakumaso pali cholumikizira cha basi yamkuwa chofanana ndi m'lifupi mwa kabati, ndi gawo la mtanda la 4X40mm.
● Kutsekedwa kwa makina: Pofuna kupewa kusokoneza ndi katundu, kupewa kutsegula kolakwika ndi kutseka kwa woyendetsa dera, ndikuteteza nthawi yamphamvu kuti isalowe molakwika; kuletsa kusintha kwa dziko lapansi ndi magetsi kuti zisatseke; kuteteza kutseka kwa kusintha kwa dziko lapansi, kabati yosinthira imatenga cholumikizira chofananira ndi makina.
The makina interlock ntchito mfundo unyolo ndi motere:
● Kulephera kwa mphamvu (operation-overhaul): Kabati yosinthira ili pamalo ogwirira ntchito, ndiko kuti, cholumikizira chapamwamba ndi chakumunsi ndi zotchingira zozungulira zili munjira yotseka, zitseko zakutsogolo ndi zakumbuyo zatsekedwa, ndipo zikugwira ntchito. . Panthawiyi, chogwirira chaching'ono chili pamalo ogwirira ntchito. Choyamba tsegulani chophwanya dera, kenako kukoka chogwirira chaching'ono kumalo a "breaking interlock". Panthawiyi, wowononga dera sangathe kutsekedwa. Lowetsani chogwirira ntchito mu dzenje laling'ono lolumikizira cholumikizira ndikuchikokera pansi kuchokera kumtunda kupita kumalo otsegulira cholumikizira, Chotsani chogwiriracho, kenako ndikuchiyika mu dzenje lapamwamba la cholumikizira cholumikizira, kukokera pansi kuchokera pamwamba kupita kumtunda kwa cholumikizira chotsegulira. udindo, ndiye chotsani chogwirira ntchito, ndikuchiyika mu dzenje la ntchito yosinthira dziko lapansi, ndikuchikankhira kuchokera pansi kupita pamwamba kuti dziko lapansi lisinthe potseka, chogwirizira chaching'ono chingathe kukokedwa ku "kukonzanso" pamalopo. nthawi. Mutha kutsegula chitseko choyamba, kutulutsa kiyi kuseri kwa chitseko ndikutsegula chitseko chakumbuyo. Ntchito yolephera mphamvu ikatha, ogwira ntchito yosamalira amasamalira ndikukonza chipinda chophwanyira dera ndi chipinda cha chingwe.
● Ntchito yotumizira mphamvu (kukonzanso-ntchito): Ngati kukonza kwatha ndipo mphamvu ikufunika, njira yoyendetsera ntchitoyo ili motere: kutseka kumbuyo, kuchotsa fungulo ndi kutseka chitseko chakutsogolo, ndikusuntha chogwirira chaching'ono kuchokera "kukonzanso". " malo pa malo a "disconnecting interlock". Pamene chitseko chakumaso chatsekedwa ndipo wosweka dera sangathe kutsekedwa, ikani chogwirira ntchito mu dzenje la ntchito ya dziko lapansi ndi kukokera pansi kuchokera pamwamba mpaka pansi kuti dziko lapansi lisinthe pamalo otseguka. Chotsani chogwirira ntchito ndikuchiyika mu dzenje la disconnector. Kanikizani pansi ndi mmwamba kuti cholumikizira chapamwamba chitseke, chotsani chogwirira ntchito, lowetsani mu dzenje la cholumikizira chapansi, ndikukankhira kuchokera pansi mpaka pansi kuti cholumikizira cham'munsi chitseke, chotsani cholumikizira. chogwirira, ndi kukokera chogwirizira chaching'ono kumalo ogwirira ntchito, wophwanya dera akhoza kutsekedwa.
● Makulidwe azinthu zonse ndi zojambula (onani Chithunzi 1, Chithunzi 2, Chithunzi 3)
