Yiziphi izici zesixhumi sekhebula?

(1) I-terminal yekhebula le-switchgear engu-35kV SF6 evalwe ngokuphelele iwukufaka yonke i-terminal kusokhethi ekhethekile etholakala ekamelweni elincane elivalwe ngokuphelele le-switchgear, futhi izingxenye eziveziwe zonke zisekelwe phansi.

(2) Amatheminali ekhebula angu-10kV SF6 avaliwe ngokuphelele (ikhabhinethi yenethiwekhi yendandatho) ahlukaniswe izixhumi ezihlukanisiwe ezine-plug-in (ezimise okwesinqe) (ze-200A) kanye nezixhumi ezihlukanisiwe ze-bolt zohlobo lwe-plug-in (ezisetshenziswa kakhulu ku-630A)). Kukhona futhi isivikelo esikhethekile se-terminal yekhebula, okungukuthi, isivikelo esikhethekile sisetshenziselwa ukumboza ingxenye ebukhoma.

Itheminali yekhebula yenziwe kusengaphambili efemini enezingxenye eziyinhloko, futhi iphumelele ukuhlolwa efemini. Itheminali yekhebula ifakwe ngokuphelele kusokhethi ekhethekile etholakala engxenyeni evalwe ngokuphelele yekhabhinethi yokushintsha, futhi ingxenye eveziwe isekelwe phansi.

2. Ukuxhumana phakathi kwetheminali yekhebula kanye nekhabhinethi yokushintsha

(1) I-terminal ye-plug-in engu-35kV ixhunywe ngama-plug ahambayo nanganyakazi, futhi i-terminal yekhebula ifakwa kusokhethi yekhebula elungiselelwe kusengaphambili yekhabhinethi yokushintsha. I-socket ihlukaniswe ngokuphelele ngaphakathi kwekhabhinethi yokushintsha, futhi ukufakwa kwezintambo akuthinti isimo sangaphakathi kwekhabhinethi yokushintsha. Isibalo 4-12 siwumdwebo odwetshiwe wokuphela kwekhebula le-plug-in elingu-35kV.

(2) Izixhumi ezihlukaniswa nge-plug-in right angle ngokuvamile zifanelekela iziphakeli ze-transformer. Ukuxhumana komugqa womhlaba kagesi nekhabhinethi yokushintsha kwakhiwe izingxenye ezishelelayo. Faka ngqo ekusekelweni kwekhabhinethi yokushintsha ngokusebenzisa ukuxhumana, bese uxhuma nengxenye kagesi yekhabhinethi yokushintsha. Ukusekelwa kuhlukaniswe ngokuphelele ngaphakathi kwekhabhinethi yokushintsha, futhi ukufakwa kwezintambo akuthinti isimo sangaphakathi sekhabhinethi yokushintsha.

(3) Isixhumi esihlukanisayo sohlobo lwebholithi eliyi-plug-in eliyi-angle kwesokudla sixhunywe ngamabholithi e-stud e-M16 emigodini yezikulufo ezisesekweni sekhabhinethi yokushintsha. Ukusekelwa kuhlukaniswe ngokuphelele ngaphakathi kwekhabhinethi yokushintsha, futhi ukufakwa kwezintambo akuthinti isimo sangaphakathi sekhabhinethi yokushintsha.

1) Isengezo sekhabhinethi yokushintsha siwukusebenzisa i-voltage kusongezo esikhethekile, bese senza ukuhlolwa kwe-standing voltage kutheminali yekhebula ngedivayisi yokuxhuma ngaphakathi kwekhabhinethi yokushintsha.

2) Izesekeli ze-cable terminal zenza ukuhlolwa kwe-standing voltage ku-plug-in cable terminal. Akudingeki ukuthi ihlukanise i-cable terminal kanye ne-switch cabinet, futhi ingenziwa ngqo ku-switch cabinet. Ngakho-ke, ingxenye yokuxhuma ye-line disparating switch ye-switch cabinet kanye ne-cable iyadingeka ukuthi ibe nekhono elifanayo le-standing voltage njenge-cable.

(2) Ukuhlolwa kukagesi wentambo yekhebula kanye nezinyathelo zokubeka phansi:

I-switchgear evalwe ngokuphelele inezinyathelo zokuvikela zokuphepha eziphelele. Izindlela zokuphepha ze-switchgear beziphelele kakhulu, ngomsebenzi wokuvimbela ukusebenza kabi, okungavimbela ukwakhiwa kwekhebula lapho ummese wokumisa ungavaliwe. Kodwa-ke, kusadingeka ukwandisa izinyathelo zokuphepha endaweni ngesikhathi sokwakhiwa kwekhebula. Ngokwezidingo ze-DL 409-1991 “Imithethonqubo Yomsebenzi Wokuphepha Kwemboni Kagesi”, lapho kusebenza endaweni yokuma kwentambo, isekethe kumele ihlolwe, ikhishwe, futhi ibekwe phansi. Kodwa-ke, le misebenzi ayikwazi ukwenziwa ezintanjeni zekhebula ezixhuma i-switchgear evalwe ngokuphelele. Ukwahlulela kokuthi intambo yekhebula inogesi noma ayinawo ugesi kungancika kuphela ekwahluleleni kwesimo sokusebenza se-switchgear, esidinga idivayisi yokuhlola kagesi ezinikele.

Ngokuhlanganiswa okuseduze komsebenzi we-switchgear kanye nomsebenzi we-cable terminal, ukuhlolwa kukagesi kanye nomsebenzi wokufaka kuzokwenziwa nge-switchgear.

1) Ukuhlolwa kukagesi ngekhabhinethi yokushintsha: Iphaneli yamathuluzi yekhabhinethi yokushintsha evalwe ngokuphelele ifakwe amadivayisi okuhlola kagesi, adlula ukuhlolwa kukagesi kwesekethe yesibili.

2) Ukuhlolwa kukagesi ngedivayisi yokuhlola kagesi ezinikele: Uma kusetshenziswa iswitshi engu-35kV evalwe ngokuphelele eneziphetho ze-plug-in, umenzi anganikeza idivayisi yokuhlola kagesi ezinikele yokuhlola kagesi ngqo izikhundla zekhebula ezingenalutho. Kodwa-ke, ngemva kokuba i-plug-in terminal isifakiwe, akunakwenzeka ukwenza ukuhlolwa kukagesi ngqo engxenyeni ye-terminal ye-cable terminal. Uma kusetshenziswa i-plug-in terminal engu-10kV, ingenza ukuhlolwa kukagesi endaweni yokuhlola kagesi egcinelwe i-cable terminal ngemishini ekhethekile enikezwe yiyo. Kodwa-ke, ulwazi lwalolu hlobo lwedivayisi yokuhlola kagesi alucacile, futhi ukusebenza okuqondile kuncike ekuthembekeni kwemishini ekhethekile ngokwayo.
