Inhloso eyinhloko yeswishi yokuhlukanisa i-high-voltage

1. Isetshenziselwa ukuhlukanisa ukunikezwa kwamandla ukuze kuqinisekiswe ukuphepha kokugcinwa, ukuze izinto zikagesi ezilungiswayo zibe nephuzu elicacile lokunqamula ekunikezeni amandla;

2. Yenza umsebenzi wokucisha ukuze ushintshe indlela yokusebenza yesistimu. Isibonelo, kumjikelezo osebenza kabili webhasi, sebenzisa inkinobho yokuhlukanisa ukuze ushintshe okokusebenza noma ulayini usuka kwelinye iqembu lamabhasi uye kwelinye iqembu lamabhasi;

3. Ngaphansi kwezimo ezithile, ingasetshenziswa ukuxhuma nokusika izifunda ezincane zamanje. Uma usebenzisa inkinobho yokuhlukanisa, le misebenzi elandelayo ingenziwa:

1) Hlukanisa futhi uvale i-voltage transformer kanye nesekhethi yokubopha.

2) Hlukanisa futhi uvale umsinga wokushaja webhasi.

3) Amaphuzu, ama-no-load transformer akhona amandla okuvusa ahlanganisiwe aweqi i-2A kanye nemigqa ye-no-load lapho i-capacitive current ingeqi ku-5A.

Tukuhlukaniswa kwe-high voltage isolation switch

1. Ngokusho kwendawo yokufaka, ihlukaniswe yaba izinhlobo ezimbili: ngaphakathi nangaphandle;

2. Ngokwenombolo yezigxobo, ihlukaniswe yaba izinhlobo ezimbili: i-unipolar ne-tripolar;

3. Ngokwenani lezinsika ezivikelayo, ihlukaniswe yaba izinhlobo ezintathu: uhlobo lwekholomu eyodwa, uhlobo lwekholomu kabili kanye nohlobo lwamakholomu amathathu;

4. Ngokwezici zesakhiwo, ihlukaniswe yaba izinhlobo ezintathu: uhlobo lwe-guillotine, uhlobo lwe-screw kanye nohlobo lwe-plug-in;

5. Ngokusho kwemisebenzi ehlukene, ihlukaniswe yaba izinhlobo ezimbili: ngokushintsha kommese ophansi futhi ngaphandle kokushintsha ummese ophansi;

6. Ngokusho kwendlela yokusebenza esetshenzisiwe, ihlukaniswe yaba: izindlela zokusebenza zemanuwali, zikagesi kanye nezomoya.

Isenzakalo esingavamile kanye nokwelashwa kwe-high voltage isolation switch

1. Ingxenye yokuxhumana yeswishi yokuhlukanisa ishise ngokweqile

Ngaphansi kwezimo ezijwayelekile, ukushintshwa kokuhlukanisa akufanele kushiswe ngokweqile. Uma inkinobho yokuhlukanisa itholakala ishisa kakhulu ngesikhathi sokusebenza, izinyathelo ezilandelayo kufanele zithathwe:

I-1) Kuhlelo lwe-double busbar, lapho iqembu elilodwa le-disbar disconnectors lifudumala, kufanele lishintshelwe kwelinye iqembu lamabhasi; lapho isixhumi sesistimu yebhasi eyodwa sishisisiwe, zama ukunciphisa umthwalo. Uma izimo zivuma, kungcono kakhulu ukukhipha iswishi yokuhlukanisa ingasebenzi. Uma amandla anganqanyulwa, kufanele alungiswe ngokushesha, ngaphandle kwalokho, ukuqapha kufanele kuqiniswe. Uma ukushisa kunzima, i-circuit breaker ehambisanayo kufanele inqanyulwe ngokuvumelana nemithethonqubo.

I-2) Uma ingxenye yokuxhumana yomshini wokuhlukanisa umugqa ishisa ngokweqile, indlela yokwelapha ifana neyomshini wokuhlukanisa ibhasi elilodwa, kodwa ngenxa yokuvikelwa kwe-breaker circuit ochungechungeni, inkinobho yokuhlukanisa ingaqhubeka nokusebenza, kodwa ukuqapha kudinga ukuqiniswa kuze kube yilapho ukuphuma kwamandla kungalungiswa.

2. Iswishi yokuhlukanisa engadonsi kahle futhi ivaleke ngokungafanele enomthwalo

Iswishi ehlukanisayo ayinawo amandla okucisha i-arc, futhi kwenqatshelwe ngokuphelele ukudonsa noma ukuvala iswishi ehlukanisayo ngomthwalo. Uma lesi simo senzeke, kufanele kubhekwane naso ngale ndlela elandelayo:

1) Donsa inkinobho yokuhlukanisa ngephutha

Uma i-blade isanda kushiya umkhawulo we-blade (i-arc ishaywe kodwa ayiphukile), i-disconnector engakavulwa kufanele ivalwe ngokushesha ukuze igweme i-arc short-circuit; uma i-disconnector ivuliwe, ayivunyelwe ukuvala, futhi isixhumi kufanele siqinisekiswe Isikhundla esivulekile, nqamula isifunda nge-circuit breaker, bese uvala inkinobho yokuhlukanisa.

2) Ukuvala ngokungalungile iswishi yokuhlukanisa

Ngemuva kokuthi i-disconnector ivalwe ngephutha ngomthwalo, ayisoze yavunyelwa ukuthi iphinde ivulwe, futhi kufanele ivulwe ngemva kokuba i-breaker circuit inqume ukujikeleza.

3. Iswishi yokuhlukanisa yenqaba ukuvula nokuvala

1) yenqaba ukuvala

Uma inkinobho yokuhlukanisa inqaba ukuvala ngenxa yokwehluleka komshini, ingasebenza ngenduku yokuvikela, noma esimweni sokuqinisekisa ukuphepha komuntu siqu, sebenzisa i-wrench ukuze uvule i-shaft ejikelezayo yeswishi yokuhlukanisa.

2) yenqaba ukuvula

Uma inkinobho yokuhlukanisa ingakwazi ukuvulwa, uma indlela yokusebenza ifriziwe, ungayinyakazisa kahle ukuze uthole indawo yesithiyo. Uma indawo yesithiyo iyingxenye yokuxhumana yeswishi, ayikwazi ukuvulwa ngenkani, ngaphandle kwalokho ibhodlela le-porcelain elisekela lingase lonakaliswe.

4. I-porcelain ye-isolation switch yonakalisiwe

Uma ukukhishwa kwe-flashover, ukuqapha kufanele kuqiniswe, futhi ukuhlanza kufanele kwenziwe ngemuva kokufaka isicelo sokuphuma kwamandla; uma ibhodlela le-porcelain elisekelayo lonakalisiwe futhi liphukile, i-breaker circuit kufanele isetshenziselwe ukunqamula umjikelezo, futhi inkinobho yokuhlukanisa eyonakele kufanele ihoxiswe ukuze ilungiswe.
