Isakhiwo Esiphelele Se-Switchgear

Isakhiwo Esiphelele Se-Switchgear (Thatha ikhabhinethi ye-vacuum circuit breaker efakwe phakathi njengesibonelo)

Uma sibheka i-switchgear ye-JYN2-10(Z) ene-voltage ephezulu njengesibonelo, isakhiwo sayo singahlukaniswa sibe izingxenye ezimbili: ikhabhinethi nemoto yesandla. Imoto yesandla yemoto yesandla ye-circuit breaker, izingxenye eziyinhloko zikagesi yi-circuit breaker (efakwe emotweni), i-grounding switch kanye nesihlalo sokuxhumana esingaguquki, njll.

Ikhabhinethi ihlukaniswe ngezigaba ezine ezizimele ngamapuleti ensimbi asekelwe phansi: igumbi lebhasi, igumbi lenqola yesandla, igumbi lezinsimbi zokudlulisela, kanye negumbi lekhebula. Uhlangothi olungemuva nolungezansi lwekhabhinethi luba yigumbi lekhebula, lapho kufakwa khona izintambo nama-transformer amanje. Ngaphezulu kwalo kukhona igumbi elikhulu lebhasi. Kunezingxenye phakathi kwezingxenye ukuqinisekisa ukuphepha ngesikhathi sokulungiswa. Ngaphambi kwekhabhinethi kukhona igumbi lokudlulisela kanye negumbi lenqola yesandla. Qhubeka usebenza. Ngomshini wokuqhuba, inqola ehlome nge-circuit breaker ihamba iye emuva naphambili ku-guide rail. Ukucindezela ngaphakathi kungenza oxhumana nabo abahambayo abangaphezulu nabangaphansi be-circuit breaker bafake esisekelweni sokuxhumana esingaguquki ukuze kuqedwe uxhumano lwesekethe; ngokuphambene nalokho, lapho i-circuit breaker iphula isekethe, donsa inqola ukuze uhlukanise oxhumana nabo abahambayo nabanganyakazi. , Kwakha igebe elisobala lokuhlukaniswa, elilingana nendima yeswishi yokuhlukanisa. Usebenzisa isithwali esizinikele, inqola ehlome ngama-circuit breaker ingacindezelwa kalula noma ikhishwe kukhabhinethi.

Uma i-circuit breaker ihluleka kakhulu noma inomonakalo omkhulu, i-truck ekhethekile ye-circuit breaker ingasetshenziswa ikhishwe emzimbeni wekhabhinethi ukuze ilungiswe. Ingaphinde ithathe indawo ye-spare circuit breaker trolley, efakwe emzimbeni wekhabhinethi.

2.1.1 Izidingo Eziyisisekelo

(1) Ukwakheka kwe-switchgear enamandla aphezulu kufanele kwenze ukusebenza okuvamile, ukuqapha kanye nomsebenzi wokulungisa i-switchgear enamandla aphezulu kube okuphephile futhi okulula. Umsebenzi wokulungisa uhlanganisa: ukulungiswa kwezingxenye, ukuhlolwa, ukuthola amaphutha kanye nokwelashwa;

(2) Kumapharamitha alinganisiwe kanye nesakhiwo esifanayo kanye nesidingo sokushintsha izingxenye kufanele zishintshelane;

(3) Yokususwa

Isiguquli se-voltage ephezulu sezingxenye ezivulekile kufanele sishintshelane uma amapharamitha alinganisiwe kanye nesakhiwo sezingxenye ezisuswayo kufana;

(4) kufanele ihlolwe ngokwemibandela yendawo yokusetshenziswa;

(5) Kuzolwela ukuba ngcono kwezobuchwepheshe futhi kube nokulinganisela kwezomnotho;

(6) Imikhiqizo emisha ekhethiwe kufanele ibe nedatha yokuhlola ethembekile futhi ifaneleke ukuhlolwa.

2.1.2 Ukunqunywa kohlelo oluyinhloko lweluphu

Isekethe eyinhloko yekhabhinethi yokushintsha ye-voltage ephezulu ibizwa nangokuthi umugqa, ngokwezidingo zangempela zesistimu yamandla kanye nohlelo lokunikezwa kwamandla nokusabalalisa, imodeli ngayinye yesikimu sesekethe esiyinhloko yekhabhinethi yokushintsha ye-voltage ephezulu inenqwaba encane, amakhulu amaningi, ngokuvamile ihlanganisa izigaba ezilandelayo: umkhumbi, ithangi lokulinganisa, ukuhlukaniswa, ikhabhinethi yenqola yesandla ephansi, amakhabhinethi e-capacitor, ikhabhinethi yokulawula kagesi ene-voltage ephezulu (F - C ark), njll.

Inhlanganisela yesikimu sesekethe esikhulu se-Switchgear ukucabangela izinkinga ezilandelayo:

(1) ngokuya ngomdwebo wesistimu eyinhloko kanye nosayizi wamanje osebenzayo weluphu eyinhloko kanye nokulawula, ukuvikelwa, ukulinganiswa kanye nezinye izidingo, khetha uhlelo lwesekethe oluyinhloko oluhambisanayo lwekhabhinethi yokushintsha;

(2) Ukukhetha phakathi kwezinhlobo zomugqa ongenayo nophumayo kanye neswitchgear.
