I. Ukuhlaziywa kanye nendlela yokwelapha yezimbangela zephutha
1. Ngemva kokuba ikhoyili inikwe amandla, othintana naye akenzi noma enze ngendlela engavamile
A. Isekhethi yokulawula ikhoyili inqanyuliwe;bheka ukuthi ingabe itheminali yezintambo iphukile noma ikhululekile.Uma kunekhefu, buyisela ucingo oluhambisanayo.Uma luxega, qinisa amatheminali ahambisanayo.
b.Ikhoyili yonakele;ukukala ukumelana kwekhoyili nge-multimeter.Uma kukhona ukumelana, buyisela ikhoyili.
c.I-thermal relay ayisethwa kabusha ngemva kwesenzo.Sebenzisa igiya lokumelana ne-multimeter ukuze ulinganise inani lokumelana phakathi kwamaphoyinti amabili okuvala angaguquki e-relay yokushisa, njengoba kunjalo, bese ucindezela inkinobho yokusetha kabusha isidluliseli sokushisa.
d.Ivoltheji yekhoyili elinganisiwe ingaphezulu kwelayini kagesi.Shintsha ikhoyili ehambisana nevoltheji yelayini yokulawula.
e.Ukucindezela kwentwasahlobo yokuxhumana noma ukucindezela kwentwasahlobo kukhulu kakhulu.Lungisa ingcindezi yasentwasahlobo noma shintsha intwasahlobo.
Othintana naye f, Inkinobho ethintwayo noma othintana naye ongumsizi inkinobho embi Hlanza othintana naye noma shintsha ngokufanele.
I-g noxhumana nabo kukhulu kakhulu.Lungisa ububanzi bokuthinta
2. Ngemva kokuba ikhoyili icishiwe, i-contactor ngeke ikhululwe noma ibambezeleke ukukhululwa.
A. Ikholomu kusistimu kazibuthe ayinayo igebe lomoya, futhi indawo kazibuthe esele inkulu kakhulu. Susa ingxenye yensimu endaweni esele yamagnetic ukuze igebe libe ngu-0.1~0.3mm, noma ube ne-0.1uF capacitor. ngokuhambisana kuzo zombili iziphetho zekhoyili.
b.Ingaphezulu le-contact core elicushiwe liwuwoyela noma linamafutha ngemva kwesikhathi sokusetshenziswa.Sula igrisi yokugqwala endaweni ewumgogodla, indawo ewumgogodla kufanele ibe isicaba, kodwa akumele ibe lula kakhulu, ngaphandle kwalokho kulula ukubangela ukukhululwa kokulibaziseka.
c.Ukusebenza kwe-anti-melting welding akulungile.Uma i-motor noma umugqa ufushane, i-high current yenza ukuthintana.Ikhanda liqiniswe ngokuqinile futhi alikwazi ukukhululwa, futhi ukuxhumana okuhlanzekile kwesiliva kulula ukuncibilikisa i-welding.Ukuxhumana okuyinhloko kwe-AC contactor kufanele kukhethwe ngesiliva. -i-alloy esekelwe ngokuncibilika okuqinile nokumelana nokushisela, njengesiliva nensimbi, isiliva ne-nickel, njll.
d.Lungisa iphutha lokulawula izintambo ngokomdwebo wokulawula izintambo.
Okwesithathu, ukushisisa ikhoyili, kushiswe noma kulimele.
A. Ukuvama kanye nezinga lamandla eringini lidlula izimfuneko zobuchwepheshe zomkhiqizo.Shintsha ikhoyili ukuze uthole ifrikhwensi kanye nokuqhubeka kwamandla.
b.I-core surface ayilingani noma igebe lomoya wekholomu likhulu kakhulu. Hlanza indawo ye-pole noma ulungise umongo, bese ubuyisela ikhoyili.
I-c, ukulimala komshini, ingxenye yokunyakaza ibambekile.Lungisa izingxenye zemishini bese ubuyisela ikhoyili.
d.Uma izinga lokushisa lendawo liphakeme kakhulu, noma ukuvala ikhoyili konakalisiwe ngenxa yokuthi umoya umanzi noma igesi igqwalile, buyisela ikhoyili.
Okwesine, umsindo kazibuthe mkhulu kakhulu.
A. Iringi yesekethe emfishane iyaphuka bese ishintsha iringi noma umongo
b.Ukucindezela kwentwasahlobo yokuxhumana kukhulu kakhulu, noma uma othintana naye ehamba kakhulu, lungisa ingcindezi yokuxhumana entwasahlobo noma unciphise ukudlula ngokweqile.
c.Iphinikhodi yokuxhuma phakathi kwe-armature nengxenye yomshini ikhululekile, noma isikulufu sokubopha sikhululekile.Faka iphinikhodi yokuxhuma bese uqinisa isikulufu se-clamp.
Eyesihlanu, enye indlela emfishane
A. Isixhumi siqoqa uthuli oluningi noma izinti ngamanzi negesi.Isikali sikawoyela senza umonakalo wokufakelwa.I-contactor kufanele ihlale ihlanzwa, igcinwe, ihlanzekile futhi yomile.
Ku-b.Ngokuvala ugesi kuphela, isikhathi sokushintsha sesixhumi esiguqulela emuva sifushane kunesikhathi se-arc yokuvutha.Yengeza izingidi zokukhiya.
Ngo c.Uma i-arc hood iphuka, noma izingxenye zokuthinta zilinyazwa yi-arc, noma buyisela izingxenye ezilimele.
Ngenhla kwezinkinga ezivamile enqubweni yokusebenza kokuxhumana, iphutha lenze ukuhlaziya kafushane, futhi labeka phambili isixazululo, enqubweni yokusebenza yangempela izohlangana nezinye izinkinga, inqobo nje uma senza kahle indlela yokuxhumana yokuxhumana, kuhlangene nesipiliyoni esicebile. in practice, izinkinga namaphutha kuyoba ukuqeqeshwa kuwufanele ukunakwa kwakho!
Umsindo wesixhumi se-AC
I-AC contactor egijima inomsindo omkhulu futhi ingelashwa ngale ndlela elandelayo:
1. Uma i-voltage yomthombo wamandla inganele futhi ukudonsa kwe-electromagnetic akwanele, kufanele sizame ukwandisa i-voltage yesifunda sokusebenza.
2. Uma isistimu kazibuthe ihlanganiswe ngendlela engafanele noma inyakaziswa noma ucezu lomshini lubhajwe, umgogodla wensimbi awukwazi ukuncishiswa, okubangela umsindo.Lolu hlelo kufanele lulungiswe ukuze luhlonze futhi luqede izimbangela zokuguquguquka.
3. Ukugqwala kwe-polar noma umzimba wangaphandle (njengesikali samafutha, uthuli, izinwele, njll.) endaweni ewumgogodla, khona-ke indawo ewumgogodla kufanele ihlanzwe.
4. Umsindo we-electromagnet ukhiqizwa ngenxa yokucindezela kwentwasahlobo okuthintana ngokweqile, ngakho-ke ngokuvamile lungisa ingcindezi yasentwasahlobo yokuxhumana.
5. Uma kwenzeka umsindo ovela ekuqhekekeni kweringi yesifunda esifushane, indandatho ewumgogodla noma emfushane kufanele ishintshwe.
6. Uma i-core pole surface wear idlulele futhi ingalingani, umgogodla kufanele ushintshwe.
7. Umjikelezo omfushane phakathi kwamajika, ngokuvamile ubuyisela ikhoyili.
Ukuze uthole iziqondiso ezengeziwe zobuchwepheshe, sicela unake i-Jingdian Port.
