Umehluko phakathi kwekhebula le-voltage ephansi nekhebula le-voltage ephezulu

Nazi izinhlobo eziningi zezintambo, kodwa eziyisisekelo kakhulu zingahlukaniswa zibe izintambo ezine-voltage ephansi kanye nezintambo ezinamandla kagesi, kodwa kanjani ukuhlukanisa kokubili?Abanye abantu bathi ingu-250V, kanti abanye bathi ingu-1000V.Uwahlukanisa kanjani amandla kagesi aphezulu kanye nomfutho ophansi?

Ngokwezindinganiso zezimboni zaseShayina, izinto zikagesi zihlukaniswe ngama-voltage aphezulu kanye ne-low voltage: i-voltage ephezulu: imishini ene-voltage engaphezu kuka-250V ukuya phansi;I-voltage ephansi: imishini ene-voltage engaphezu kuka-250V ukuya phansi.Ngokwemithetho yezokuphepha kolayini kagesi ka-2009, umsebenzi kagesi uhlukaniswe ngama-voltage aphezulu kanye ne-low voltage

Imishini kagesi enamandla amakhulu: izinga likagesi ngu-1000V nangaphezulu;imishini kagesi ene-voltage ephansi: izinga likagesi lingaphansi kuka-1000V;

Ngokuvamile, ulayini wamandla kagesi aphezulu ubhekisela kulayini we-3 ~ 10kV;ulayini we-voltage ephansi ubhekisa kulayini ongu-220/380 V.

Indlela yokuhlukanisa i-voltage ye-high voltage wire ngamehlo enqunu imi kanje:

1. Yazi izinga likagesi.

Embonini yamandla kagesi yaseShayina, amazinga kagesi avamile angama-220 V, 380 V, 1000 V, 10000 V, 35 000 V, 110 000 V, 220 000 V, 500 000 V, njll. Ngokuvamile, 220 V kanye no-380 V babhekwa. njengamandla kagesi aphansi, ikakhulukazi kagesi wasendlini;futhi ngaphezu kuka-35000 V kukhona amandla kagesi aphezulu, ikakhulukazi asetshenziselwa ukudluliswa kwamandla.Phakathi kokubili kukhona ukucindezela okuphakathi.Kufanele kuphawulwe ukuthi ukuthinta izintambo ezinamandla kagesi noma ukwenza umsebenzi obukhoma ngaphansi komugqa kuyingozi enkulu.

2. Thola imigqa yamandla kagesi aphansi.

Ulayini we-voltage ophansi wangaphandle unezici ezimbalwa ezisobala

1) Ngokuvamile, isigxobo sikasimende singeqi amamitha angu-5.

2) Ubukhulu bezintambo buyafana, futhi isibalo sezintambo siphindaphindwe ngo-4. Lokhu kungenxa yokuthi izintambo ezine-voltage ephansi ngokuvamile zisebenzisa isistimu yezintambo ezine zezigaba ezintathu.Uma lezi zici zitholakala, kunganqunywa ukuthi i-voltage yomugqa wocingo ingu-380 V futhi i-voltage yesigaba ingu-220 v. (isigaba se-voltage singumugqa we-voltage emhlabathini, i-voltage yomugqa i-voltage phakathi kwemigqa emibili)

3. Thola imigqa yamandla kagesi aphakathi nendawo naphezulu.

Imigqa yamandla kagesi aphakathi nendawo naphezulu nawo anezici ezisobala

1) Uma ubukhulu bezintambo bufana, inani lezintambo liphindaphinda ka-3. Lokhu kungenxa yokuthi izintambo zokudlulisela ngokuvamile zisebenzisa ukudluliselwa kwezigaba ezintathu.Uma lezi zici zikhona, kunganqunywa ngokuyisisekelo ukuthi ucingo luyi-10000 volts.

2) Uma ukushuba kocingo kuhlukile, inani lemigqa ewugqinsi liyi-multiple of 3, futhi kunezintambo ezimbili kuphela ezincane, okucatshangwa ukuthi zisendaweni ephakeme kakhulu.Lokhu kungenxa yokuthi ucingo oluncane alusetshenziselwa ukudlulisa amandla, kodwa ukuvikela umbani, owaziwa nangokuthi umqhubi wombani.Uma lezi zici zikhona, kunganqunywa ukuthi ucingo luwumugqa we-voltage ephezulu.

4. Bheka futhi umugqa wamandla kagesi aphezulu.

Ukuze kuthuthukiswe umthamo wokudlulisa, izintambo ezinamandla kagesi zivame ukusebenzisa amakhondatha ahlukanisiwe.Ngokuvamile, ucingo olulodwa lusetshenziselwa isigaba esisodwa.Manje kusetshenziswa izinyanda ezimbalwa zocingo ukuze kuthathelwe indawo eyokuqala.Ukwazi lokhu, kulula ukwahlulela izinga le-voltage yocingo.1) Isigaba esisodwa esinocingo olulodwa singama-volts angu-110000;2) isigaba esisodwa esinezintambo ezimbili singu-220000 volts;3) isigaba esisodwa esinezintambo ezine yi-500000 volts.

Ekuxhumaneni kwethu kwansuku zonke nemigqa ye-voltage ephezulu, kodwa lapho sibhekene nemigqa ephakathi nendawo nephansi, kusadingeka siqaphele.Minyaka yonke, abantu abangenakubalwa babulawa ukushaqeka kukagesi, ngakho-ke kungakhathaliseki ukuthi hlobo luni lwekhebula olusetshenziswayo, kufanele sisebenzise ikhebula elijwayelekile likazwelonke eliqinisekisa ikhwalithi.Ukuze kuthuthukiswe ikhwalithi yemikhiqizo, imikhiqizo ikhiqizwa ngokuhambisana ngokuqinile namazinga kazwelonke (GB / JB) kanye ne-International Electrotechnical Commission (IEC).Ibhizinisi seliphumelele isitifiketi se-ISO9001:2008 esijwayelekile samazwe ngamazwe, lathola ilayisense kazwelonke yokukhiqiza umkhiqizo wezimboni kanye ne-China National Compulsory Product Certification (isitifiketi se-CCC).Phakathi kwazo, ubuchwepheshe bokukhiqiza bekhebula le-XLPE buhamba phambili embonini, Ukuze ulandele eduze ukwakhiwa kwe-State Grid, inkampani iphinde yathenga ulayini wokukhiqiza ikhebula elixhumene ne-35kV elithuthukisiwe, isinyathelo esisodwa sokukhiqiza i-silane cross-linked. umugqa kanye neminye imigqa ethuthukisiwe yokukhiqiza intambo nekhebula.Kungakhathaliseki ukuthi hlobo luni lwekhebula, ikhebula le-Zhujiang lizohlala likunikeza ikhwalithi engcono kakhulu!
