Ulwakhiwo
● I-XGN-12 yokutshintsha ikhabhinethi yibhokisi yentsimbi edibeneyo. Isakhelo sekhabhinethi sidityaniswe ngentsimbi ye-angle. Ikhabhinethi yohlulwe kwigumbi lokuqhekeza isekethe, igumbi lebhasi, igumbi lekhebula, igumbi lokuhambisa, njl., lihlulwe ngamacwecwe ensimbi.
● Igumbi le-breaker circuit lisezantsi kwekhabhinethi. Ukujikeleza kwesiphambano sesiphaluka kudibaniswe nendlela yokusebenza ngentonga yokubopha. I-terminal ye-wiring ephezulu ye-circuit breaker idibaniswe ne-disconnector ephezulu, i-terminal ye-wiring ephantsi ye-circuit breaker idibaniswe ne-transformer yangoku, kwaye i-transformer yangoku idibene ne-wiring terminal ye-disconnector ephantsi. Kwaye igumbi le-breaker circuit likwaxhotyiswe ngeshaneli yokukhupha uxinzelelo. Ukuba i-arc yangaphakathi iyenzeka, igesi inokukhulula uxinzelelo ngokusebenzisa umjelo wokukhupha.
● Igumbi lebhasi likwindawo ephezulu ngasemva kwekhabhinethi. Ukuze kuncitshiswe ukuphakama kwekhabhinethi, iibhasi zebhasi zicwangciswe kwimilo "yepini", exhaswa yi-7350N yokugoba i-porcelain insulators, kwaye iibhasi zebhasi zixhunyiwe kwi-terminal ye-disconnector terminal, inokuqhawulwa phakathi kweebhasi ezimbini zekhabhinethi ezikufutshane.
● Igumbi lekhebula lisemva kwendawo engezantsi yekhabhinethi. I-insulator exhasayo kwigumbi lekhebula inokuxhotyiswa ngezixhobo zokujonga i-voltage, kwaye iintambo zigxininiswe kwi-bracket. Kwiplani yoqhagamshelo oluphambili, eli gumbi ligumbi lekhebula loqhagamshelwano. Igumbi le-relay liphambi kwendawo ephezulu yekhabhinethi. Ibhodi yokufakela yangaphakathi ingafakwa kunye neereyidi ezahlukeneyo. Kukho izibiyeli ze-terminal block kwigumbi. Umnyango unokufakwa kunye namacandelo esibini njengezixhobo zokubonisa kunye namacandelo omqondiso. Umphezulu unokuxhotyiswa ngebhasi encinci yesibini.
● Indlela yokusebenza ye-circuit breaker ifakwe kwicala lasekhohlo langaphambili, kwaye ngaphezu kwayo yindlela yokusebenza kunye ne-interlocking ye-disconnector. Isixhobo sokutshintsha silungisa amacala amabini. Amacandelo esibini egumbi lokubuyisela, ukugcinwa kwendlela yokusebenza, i-mechanical interlocking kunye neengxenye zokuhambisa, kunye ne-breaker circuit ihlolwe kwaye ilungiswe ngaphambili. Izikhululo eziphambili zebhasi kunye neekhebula zilungiswa ngasemva, kwaye izibane zifakwe kwigumbi lokuqhawula isiphaluka. Ngaphantsi komnyango wangaphambili unikezwa ibha yebhasi yobhedu ephantsi ehambelana nobubanzi bekhabhinethi, kunye necandelo lomnqamlezo we-4X40mm.
● I-Mechanical interlocking: Ukuze unqande i-disconnector ngomthwalo, ukukhusela ukuvulwa okungalunganga kunye nokuvala i-breaker circuit, kwaye uthintele ikhefu elinamandla ukuba lingene ngephutha; thintela ukutshintsha komhlaba ngombane ekuvaleni; ukuthintela ukuvalwa kokutshintsha komhlaba, ikhabhinethi yokutshintsha ithatha i-interlock ehambelanayo yomatshini.
Umgaqo wokusebenza kwe-mechanical interlock wekhonkco umi ngolu hlobo lulandelayo:
● Umsebenzi wokungaphumeleli kwamandla (ukusebenza-ukulungiswa): Ikhabhinethi yokutshintsha ikwindawo yokusebenza, oko kukuthi, i-disconnector ephezulu kunye nezantsi kunye ne-circuit breakers zikwisimo sokuvala, iingcango zangaphambili kunye neengcango zangasemva zivaliwe, kwaye zisebenza ngokuqhubekayo. . Ngeli xesha, isiphatho esincinci sikwindawo yokusebenza. Okokuqala vula i-breaker circuit, kwaye emva koko utsale isiphatho esincinci kwindawo "ye-breaking interlock". Ngeli xesha, i-breaker circuit ayikwazi ukuvalwa. Faka umqheba wokusebenza kumngxuma wokusebenza wokuqhawula umngxuma osezantsi kwaye uwutsale ezantsi ukusuka phezulu ukuya kwindawo esezantsi yokuvula isiqhagamsheli, Susa isiphatho, uze usifake kumngxunya ongaphezulu wokuqhawuka wesiqhagamsheli, usitsale phantsi ukusuka phezulu ukuya kwindawo ephezulu yokuvula isiqhagamshelwano. indawo, emva koko susa umqheba wokusebenza, uwufake kumngxunya wokusebenza weswitshi yomhlaba, kwaye uyityhale ukusuka ezantsi ukuya phezulu ukwenza umhlaba utshintshe kwindawo yokuvala, isiphatho esincinci sinokutsalwa ukuya kwindawo "yokulungisa" kule ndawo. ixesha. Ungavula umnyango wangaphambili kuqala, ukhuphe isitshixo emva kocango kwaye uvule ucango lwangemva. Emva kokuba umsebenzi wokungaphumeleli kombane ugqityiwe, abasebenzi bolondolozo baya kugcina kwaye balungise igumbi le-breaker circuit kunye negumbi lekhebula.
● Umsebenzi wothumelo lwamandla (ulungiso-ukusebenza): Ukuba ugcino lugqityiwe kwaye umbane uyafuneka, inkqubo yokusebenza imi ngolu hlobo lulandelayo: vala ngasemva, susa isitshixo kwaye uvale umnyango wangaphambili, kwaye uhambise isiphatho esincinci kwi-"overhaul". " indawo kwindawo "yokuqhawula i-interlock". Xa umnyango wangaphambili uvaliwe kwaye i-breaker circuit ayinakuvalwa, faka isibambo sokusebenza kumngxuma wokusebenza wenguqu yomhlaba kwaye uyikhuphe phantsi ukusuka phezulu ukuya phezulu ukuze wenze umhlaba utshintshe kwindawo evulekileyo. Susa isiphatho sokusebenza kwaye usifake kumngxuma wokusebenza we-disconnector. Ukutyhala phantsi naphezulu ukwenza isiqhagamshelo esingentla kwindawo yokuvala, susa isiphatho sokusebenza, sifake kumngxuma wokusebenza we-disconnector esezantsi, kwaye utyhale ukusuka ezantsi ukuya phezulu ukwenza isiqhagamshelo esisezantsi kwindawo yokuvala, khupha ukusebenza. phatha, kwaye utsale isiphatho esincinci kwindawo yokusebenza, i-breaker circuit inokuvalwa.
● Ubungakanani bemveliso jikelele kunye nomzobo wesakhiwo (jonga uMzobo 1, umzobo 2, umzobo 3)
