Kutheni le nto iinjini zombane kunokwenzeka ukuba ziphele ngoku kunangaphambili?
1. Ngenxa yophuhliso oluqhubekayo lwetekhnoloji ye-insulation, uyilo lwe-motor lufuna zombini imveliso eyongeziweyo kunye nokunciphisa umthamo, ukwenzela ukuba umthamo we-thermal we-motor entsha uyancipha kwaye uncinci, kwaye umthamo wokulayisha uyancipha kwaye ube buthathaka;ngenxa yokuphuculwa kweqondo le-automation ye-automation, i-motor iyadingeka ukuba isebenze rhoqo ukuqala, ukunyathela, ukuya phambili kunye nokujikeleza umva, kunye neendlela eziguqukayo zomthwalo, ezibeka phambili iimfuno eziphezulu zesixhobo sokukhusela imoto.Ukongeza, i-motor inendawo ebanzi yesicelo kwaye ihlala isebenza kwiindawo ezibukhali kakhulu, ezinje ngokufuma, ubushushu obuphezulu, uthuli, ukubola kunye nezinye izihlandlo.Ukongeza, kukho izitenxo ekulungisweni kweemoto kunye nokushiyeka kulawulo lwezixhobo.Konke oku kwenza iinjini zanamhlanje zithande ukonakaliswa kunangaphambili.
Kutheni le nto impembelelo yokukhusela yezixhobo zokukhusela zendabuko ayifanelekanga?
2. Izixhobo zemveli zokukhusela iimoto ziyi-fuses kunye ne-thermal relays.I-Fuse sesona sixhobo sokuqala nesilula sokukhusela ukusisebenzisa.Enyanisweni, i-fuse isetyenziselwa ukukhusela umbane wombane kunye nokunciphisa ukwandiswa koluhlu lwesiphoso xa kwenzeka impazamo emfutshane.Akukho nzululwazi ukucinga ukuba i-fuse inokukhusela i-motor kwi-short-circuit okanye i-overload.Andazi, oku kunokwenzeka ukuba kubangele ukuba injini yonakalise imoto ngenxa yokusilela kwesigaba.Iireyilayi ze-Thermal zezona zixhobo zisetyenziswa kakhulu zokukhusela ukugcwala kwemoto.Nangona kunjalo, i-thermal relay inomsebenzi omnye, uvakalelo oluphantsi, impazamo enkulu kunye nokuzinza okubi, okuye kwaqatshelwa ngoninzi lwabasebenzi bombane.Zonke ezi ziphene zenza ukhuseleko lwemoto lungathembeki.Oku kunjalo kwakhona;nangona izixhobo ezininzi zixhotyiswe nge-thermal relays, isenzeko somonakalo wemoto ochaphazela imveliso eqhelekileyo isaxhaphakile.
Umgaqo wokukhetha umkhuseli?
3. Injongo yokukhetha isixhobo sokukhusela i-motor ayikona nje ukwenza ukuba i-motor ikwazi ukusebenzisa ngokupheleleyo umthamo wayo ogqithisiweyo, kodwa nokuphepha umonakalo, kunye nokuphucula ukuthembeka kwenkqubo yokuqhuba umbane kunye nokuqhubeka kwemveliso.Ngelo xesha, xa ukhetha isixhobo sokukhusela, izinto ezininzi eziphikisanayo kufuneka ziqwalaselwe, oko kukuthi, ukuthembeka, uqoqosho, isakhiwo esilula, ukusebenza kakuhle kunye nokugcinwa, njl.Kuphela xa isixhobo sokukhusela esilula asikwazi ukuhlangabezana neemfuno, okanye xa iimfuno eziphezulu zibekwe kwiimpawu zokukhusela, ukusetyenziswa kwesixhobo sokukhusela esiyinkimbinkimbi siqwalaselwa.
Oyena mkhuseli wemoto ofanelekileyo?
4. Umkhuseli ofanelekileyo wemoto ayisiyiyo eyona nto isebenzayo, okanye ebizwa ngokuba yinto ehamba phambili, kodwa kufuneka ibe yeyona nto isebenzayo.Ngoko kutheni iluncedo?I-practical kufuneka ihlangabezane nokuthembeka, uqoqosho, lula kunye nezinye izinto, kunye nokusebenza kweendleko eziphezulu.Ngoko yintoni enokuthenjwa?Ukuthembeka kufuneka kuqala kuhlangabezane nokuthembeka kwemisebenzi, efana ne-overcurrent kunye nesigaba sokungaphumeleli kwesigaba, ekufuneka sisebenze ngokuthembekileyo ngenxa yokungaphumeleli kwe-overcurrent kunye nesigaba okwenzeka kwiimeko ezahlukeneyo, iinkqubo kunye neendlela.Okwesibini, ukuthembeka kwayo (ekubeni umkhuseli kukukhusela abanye, kufuneka abe nokuthembeka okuphezulu ngokukodwa) kufuneka abe nokuguquguquka, ukuzinza kunye nokuqina kwiindawo ezahlukeneyo ezinzima.Uqoqosho: Yamkela uyilo oluphambili, ulwakhiwo olufanelekileyo, imveliso ekhethekileyo kunye nenkulu, ukunciphisa iindleko zemveliso, kunye nokuzisa izibonelelo zoqoqosho eziphezulu kakhulu kubasebenzisi.Ukulungeleka: Kufuneka ubuncinane ifane ne-thermal relays ngokufakela, ukusetyenziswa, ukulungiswa, i-wiring, njl., njengento elula kwaye elula ngokusemandleni.Ngenxa yoko, iingcali ezichaphazelekayo ziye zaxela ixesha elide ukuba ukwenza lula isixhobo sokukhusela i-elektroniki, isicwangciso soyilo ngaphandle kwe-transformer yamandla (passive) kufuneka siyilwe kwaye yamkelwe, kwaye i-semiconductor (efana ne-thyristor) kufuneka isetyenziswe. buyisela i-electromagnetic actuator ngabafowunelwa.isiqalelo.Ngale ndlela, kunokwenzeka ukwenza isixhobo sokukhusela esinenani elincinci lamacandelo.Siyazi ukuba imithombo esebenzayo iya kukhokelela ngokungathembekiyo.Enye idinga amandla okusebenza ngokusebenza okuqhelekileyo, kwaye xa enye iphuma kwisigaba, ngokuqinisekileyo iya kuphulukana namandla okusebenza.Le yinkcaso engenakoyiswa.Ukongeza, kufuneka inikwe amandla ixesha elide, kwaye ichaphazeleka ngokulula kukuguquguquka kwamandla ombane wegridi kunye nezothuso ezinkulu zangoku, kwaye inqanaba layo lokungaphumeleli liya kwandiswa kakhulu.Ke ngoko, imboni yokhuseleko lweemoto ithatha inyathelo elisebenzayo kunye nelokungenzi nto njengenkqubela phambili yetekhnoloji.Njengomsebenzisi, iimveliso zokwenziwa kufuneka ziqwalaselwe kuqala xa ukhetha.Ubume bophuhliso lokhuseleko lweemoto.
Okwangoku, umkhuseli wemoto uye waphuhliswa ukusuka kuhlobo lomatshini kwixesha elidlulileyo ukuya kuhlobo lwe-elektroniki kunye nohlobo olukrelekrele, olunokuthi lubonise ngokuthe ngqo okwangoku, i-voltage, iqondo lobushushu kunye nezinye iiparameters zemoto, enovakalelo oluphezulu, ukuthembeka okuphezulu, okuninzi. imisebenzi, ukulungisa ingxaki, kunye neentlobo zeempazamo ezicacileyo emva kwesenzo sokukhusela., engagcini nje ukunciphisa umonakalo we-motor, kodwa iphinda iququzelele kakhulu isigwebo sesiphoso, esilungele ukuphathwa kakubi kwendawo yokuvelisa kunye nokunciphisa ixesha lokubuyisela.Ukongeza, itekhnoloji yokufumanisa i-motor eccentricity ye-motor eccentricity isebenzisa i-motor air-gap magnetic field yenza kube lula ukujonga imeko yokunxiba imoto kwi-intanethi.Ijika libonisa umkhwa wokutshintsha kwe-eccentricity yemoto, kwaye inokubona kwangoko ukunxiba kunye nesangqa sangaphakathi, isangqa sangaphandle kunye nezinye iimpazamo.Ukufunyaniswa kwangethuba, unyango kwangoko, ukuthintela iingozi ezitshayelayo.
