Ukuhlolwa kwe-relayrelay I-Relay iyithuluzi elibalulekile lemitha kagesi ehlakaniphile ekhokhelwa kusengaphambili. Isikhathi sokuphila kwe-relay sinquma isikhathi sokuphila kwemitha kagesi ngezinga elithile. Ukusebenza kwedivayisi kubaluleke kakhulu ekusebenzeni kwemitha kagesi ehlakaniphile ekhokhelwa kusengaphambili. Kodwa-ke, kunezinhlobo eziningi zabakhiqizi be-relay basekhaya nabangaphandle, abahluke kakhulu esikalini sokukhiqiza, izinga lobuchwepheshe kanye nemingcele yokusebenza. Ngakho-ke, abakhiqizi bemitha yamandla kumele babe nesethi yamadivayisi okuthola aphelele lapho behlola futhi bekhetha ama-relay ukuqinisekisa ikhwalithi yamamitha kagesi. Ngesikhathi esifanayo, i-State Grid iphinde yaqinisa ukutholakala kwesampula kwamapharamitha okusebenza kwe-relay kumamitha kagesi ahlakaniphile, okudinga nemishini yokuthola ehambisanayo ukuhlola ikhwalithi yamamitha kagesi akhiqizwa abakhiqizi abahlukene. Kodwa-ke, imishini yokuthola i-relay ayinayo nje into eyodwa yokuthola, inqubo yokuthola ayikwazi ukwenziwa ngokuzenzakalela, idatha yokuthola idinga ukucutshungulwa futhi ihlaziywe ngesandla, futhi imiphumela yokuthola inezindlela ezahlukene zokungahleliwe kanye nokwenziwa. Ngaphezu kwalokho, ukusebenza kahle kokuthola kuphansi futhi ukuphepha akunakuqinisekiswa [7]. Eminyakeni emibili edlule, i-State Grid iye yalinganisa kancane kancane izidingo zobuchwepheshe zamamitha kagesi, yakha amazinga afanele embonini kanye nezincazelo zobuchwepheshe, ezibeka phambili ubunzima obuthile bobuchwepheshe bokuthola amapharamitha okudlulisela, njengomthamo wokulayisha nokuvala we-relay, ukuhlolwa kwezimpawu zokushintsha, njll. Ngakho-ke, kuyaphuthuma ukutadisha idivayisi ukuze kutholakale ukutholakala okuphelele kwamapharamitha okusebenza kokudlulisela [7]. Ngokwezidingo zokuhlolwa kwamapharamitha okusebenza kokudlulisela, izinto zokuhlola zingahlukaniswa ngezigaba ezimbili. Esinye yizinto zokuhlola ezingenawo ugesi womthwalo, njengenani lesenzo, ukumelana kokuthintana kanye nokuphila komshini. Esesibili sinezinto zokuhlola zamanje zomthwalo, njenge-voltage yokuthintana, impilo kagesi, umthamo wokulayisha ngokweqile. Izinto zokuhlola eziyinhloko zethulwa kafushane kanje: (1) inani lesenzo. I-voltage iyadingeka ekusebenzeni kokudlulisela. (2) Ukumelana kokuthintana. Inani lokumelana phakathi koxhumana nabo ababili lapho kuvalwa ugesi. (3) Impilo yomshini. Izingxenye zomshini uma kungekho monakalo, inani lezikhathi isenzo sokushintshana kokudlulisela. (4) I-voltage yokuthintana. Lapho ukuxhumana kukagesi kuvaliwe, ugesi othile usetshenziswa kusekethe yokuxhumana kagesi kanye nenani le-voltage phakathi koxhumana nabo. (5) Impilo kagesi. Uma i-voltage elinganisiwe isetshenziswa kuzo zombili iziphetho ze-relay driving coil kanye nomthwalo wokumelana olinganisiwe usetshenziswa ku-contact loop, umjikelezo ungaphansi kwezikhathi ezingu-300 ngehora kanti umjikelezo womsebenzi ungu-1∶4, izikhathi zokusebenza ezithembekile ze-relay. (6) Umthamo wokulayisha ngokweqile. Uma i-voltage elinganisiwe isetshenziswa kuzo zombili iziphetho ze-relay driving coil kanye nezikhathi ezingu-1.5 zomthwalo olinganisiwe zisetshenziswa ku-contact loop, izikhathi zokusebenza ezithembekile ze-relay zingatholakala ngemvamisa yokusebenza yezikhathi (10±1)/min [7]. Izinhlobo, isibonelo,, izinhlobo eziningi ezahlukene ze-relay, zingahlukaniswa ngesivinini se-input voltage relay, i-current relay, i-time relay, i-pressure relay, njll., ngokwesimiso somsebenzi zingahlukaniswa zibe yi-electromagnetic relay, i-induction type relay, i-electric relay, i-electronic relay, njll., ngokwenhloso zingahlukaniswa zibe yi-control relay, i-relay protection, njll., Ngokwefomu lokuguquguquka lokufaka lingahlukaniswa libe yi-relay kanye ne-measurement relay. [8]Kungakhathaliseki ukuthi i-relay isekelwe ekubeni khona noma ukungabikho kokufaka, i-relay ayisebenzi uma kungekho okokufaka, isenzo sokudlulisa uma kukhona okokufaka, njenge-relay ephakathi, i-relay ejwayelekile, i-relay yesikhathi, njll. [8]Ukulinganisa i-relay kusekelwe ekushintsheni kokufaka, okokufaka kuhlala kukhona lapho kusebenza, kuphela lapho okokufaka kufinyelela inani elithile le-relay kuzosebenza, njenge-relay yamanje, i-relay ye-voltage, i-relay yokushisa, i-relay yesivinini, i-relay yokucindezela, i-relay yezinga loketshezi, njll. [8]I-relay ye-electromagnetic Umdwebo weskimu wesakhiwo se-relay ye-electromagnetic Iningi lama-relay asetshenziswa kumasekethe okulawula ama-relay e-electromagnetic. I-relay ye-electromagnetic inezici zesakhiwo esilula, intengo ephansi, ukusebenza okulula nokugcinwa, umthamo omncane wokuxhumana (ngokuvamile ngaphansi kwe-SA), inani elikhulu loxhumana nabo futhi akukho amaphuzu amakhulu nasizayo, akukho divayisi yokucisha i-arc, usayizi omncane, isenzo esisheshayo nesinembile, ukulawula okubucayi, okuthembekile, njalo njalo. Isetshenziswa kabanzi ohlelweni lokulawula olune-voltage ephansi. Ama-relay e-electromagnetic asetshenziswa kakhulu afaka ama-relay wamanje, ama-relay e-voltage, ama-relay aphakathi kanye nama-relay amancane ahlukahlukene. [8] Isakhiwo se-electromagnetic relay kanye nesimiso sokusebenza sifana ne-contactor, ikakhulukazi esakhiwe ngendlela ye-electromagnetic kanye nokuxhumana. Ama-electromagnetic relay anama-DC kanye ne-AC. I-voltage noma i-current ingezwa kuzo zombili iziphetho ze-coil ukuze kukhiqizwe amandla kagesi. Lapho amandla kagesi edlula amandla okusabela kwentwasahlobo, i-armature idonswa ukuze kwenziwe ukuthi oxhumana nabo abavame ukuvula nabavamise ukuvalwa bahambe. Lapho i-voltage noma i-current ye-coil yehla noma inyamalala, i-armature iyakhishwa bese oxhumana nabo behlelwa kabusha. [8] I-Thermal relay I-Thermal relay isetshenziselwa kakhulu ukuvikela imishini kagesi (ikakhulukazi i-motor) overload. I-Thermal relay uhlobo lomsebenzi olusebenzisa isimiso sokushisa samanje semishini kagesi, iseduze ne-motor vumela izici zokulayisha ngokweqile zezimpawu zesikhathi esiphambene, ikakhulukazi ezisetshenziswa kanye ne-contactor, esetshenziselwa ukuvikela ukulayisha ngokweqile kwe-motor yesigaba sesithathu asynchronous kanye nokwehluleka kwesigaba kwemoto yesigaba sesithathu asynchronous ekusebenzeni kwangempela, ivame ukubhekana nazo ngenxa yezizathu zikagesi noma zemishini ezifana nokukhula kwamandla kagesi, ukulayisha ngokweqile kanye nokwehluleka kwesigaba). Uma ukudlula kwamandla kagesi kungekubi, isikhathi sifushane, futhi ama-windings angadluli ukuphakama kokushisa okuvunyelwe, lokhu kukhuphuka kwamandla kagesi kuvunyelwe; Uma i-over-current inzima futhi ihlala isikhathi eside, izosheshisa ukuguga kwe-insulation yemoto futhi ishise ngisho nemoto. Ngakho-ke, idivayisi yokuvikela imoto kufanele ibekwe kusekethe yemoto. Kunezinhlobo eziningi zamadivayisi okuvikela imoto asetshenziswa njalo, futhi evame kakhulu i-metal plate thermal relay. i-metal plate type thermal relay inezigaba ezintathu, kunezinhlobo ezimbili ezinokuvikelwa kwesigaba nokungavinjelwa. [8]I-Time relay Isikhathi relay sisetshenziselwa ukulawula isikhathi kusekethe yokulawula. Uhlobo lwayo lukhulu kakhulu, ngokwesimiso sayo sesenzo lungahlukaniswa ngohlobo lwe-electromagnetic, uhlobo lwe-air damping, uhlobo lukagesi kanye nohlobo lwe-electronic, ngokwesimo sokulibaziseka singahlukaniswa ngokubambezeleka kokulibaziseka kwamandla kanye nokubambezeleka kokulibaziseka kwamandla. I-air damping time relay isebenzisa isimiso sokuminyanisa umoya ukuthola ukubambezeleka kwesikhathi, okwakhiwa yindlela ye-electromagnetic, indlela yokubambezeleka kanye nesistimu yokuxhumana. Indlela ye-electromagnetic iyi-direct-acting double E-type iron core, uhlelo lokuxhumana lusebenzisa i-I-X5 micro switch, futhi indlela yokubambezeleka isebenzisa i-airbag damper. [8]ukuthembeka1. Ithonya lendawo ekuthembekeni kokudluliselwa: isikhathi esimaphakathi phakathi kokwehluleka kwama-relay asebenza ku-GB kanye ne-SF siphezulu kakhulu, sifinyelela ku-820,00h, kanti endaweni ye-NU, singama-600,00h kuphela. [9]2. Ithonya lezinga lekhwalithi ekuthembekeni kokudluliselwa: lapho kukhethwa ama-relay ebanga lekhwalithi ye-A1, isikhathi esimaphakathi phakathi kokwehluleka singafinyelela ku-3660000h, kanti isikhathi esimaphakathi phakathi kokwehluleka kwama-relay ebanga le-C singu-110000, ngomehluko wezikhathi ezingu-33. Kungabonakala ukuthi izinga lekhwalithi lama-relay linethonya elikhulu ekusebenzeni kwawo kokuthembeka. [9]3, ithonya ekuthembekeni kwefomu lokuxhumana lokudluliselwa: ifomu lokuxhumana lokudluliselwa lizophinde lithinte ukuthembeka kwalo, ukuphonsa okukodwa ukuthembeka kohlobo lokudluliselwa kwakuphakeme kunenombolo yohlobo olufanayo lommese oluphindwe kabili, ukuthembeka kuncipha kancane kancane ngokukhuphuka kwenani lommese ngesikhathi esifanayo, isikhathi esimaphakathi phakathi kokwehluleka ukuphonsa okukodwa okukodwa ukudluliselwa kommese okune kabili izikhathi ezingu-5.5. [9]4. Ithonya lohlobo lwesakhiwo ekuthembekeni kwerelay: kunezinhlobo ezingu-24 zesakhiwo serelay, futhi uhlobo ngalunye lunomthelela ekuthembekeni kwaso. [9]5. Ithonya lokushisa ekuthembekeni kwerelay: izinga lokushisa lokusebenza kwerelay liphakathi kuka--25 ℃ no-70 ℃. Ngokukhuphuka kwezinga lokushisa, isikhathi esimaphakathi phakathi kokwehluleka kwerelay sincipha kancane kancane. [9]6. Ithonya lesilinganiso sokusebenza ekuthembekeni kwerelay: Ngokukhuphuka kwezinga lokusebenza kwerelay, isikhathi esimaphakathi phakathi kokwehluleka ngokuyisisekelo sibonisa umkhuba wokwehla okukhulu. Ngakho-ke, uma isekethe eklanyiwe idinga ukuthi irelay isebenze ngesivinini esikhulu kakhulu, kuyadingeka ukuthola ngokucophelela irelay ngesikhathi sokulungiswa kwesekethe ukuze ishintshwe ngesikhathi. [9]7. Ithonya lesilinganiso samanje ekuthembekeni kwerelay: isilinganiso samanje esibizwa ngokuthi isilinganiso samanje yisilinganiso samanje okusebenza werelay kumanje olinganiselwe womthwalo. Isilinganiso samanje sinethonya elikhulu ekuthembekeni kwe-relay, ikakhulukazi uma isilinganiso samanje singaphezu kuka-0.1, isikhathi esimaphakathi phakathi kokwehluleka sincipha ngokushesha, kuyilapho lapho isilinganiso samanje singaphansi kuka-0.1, isikhathi esimaphakathi phakathi kokwehluleka sihlala sifana, ngakho-ke umthwalo onomthamo wamanje olinganisiwe ophezulu kufanele ukhethwe ekwakhiweni kwesekethe ukuze kuncishiswe isilinganiso samanje. Ngale ndlela, ukuthembeka kwe-relay ngisho nesekethe yonke ngeke kuncishiswe ngenxa yokuguquguquka kwamandla asebenzayo.
