10kv High Voltage Equipment For Hydropower Plant
10kv High Voltage Equipment For Hydropower Plant
Kuyidivayisi yokusabalalisa amandla ephelele ye-3~12kV yezigaba ezintathu zebhasi elilodwa le-AC 50HZ kanye nesistimu yesigaba sebhasi elilodwa. Ikakhulukazi esetshenziswa ezimbonini zikagesi, amajeneretha amancane naphakathi nendawo okuhambisa amandla, amabhizinisi ezimboni kanye nezimayini, ukusatshalaliswa kwamandla kanye neziteshi ezingaphansi zezinhlelo zikagesi, ukwamukela amandla, ukudluliswa kwamandla, kanye nokuqaliswa kwemoto enamandla kagesi amakhulu, njll.
1. Inqubo yokuvala imi kanje:
a. Vala iminyango ephakathi nendawo nephansi, bese uyikhiya ngezingidi kazibuthe.
b. Lapho i-circuit breaker ivaliwe, ipuleti lomyalo ebhodini le-analog kufanele lishintshwe nepuleti lomyalo esibambeni sokushintsha kokulawula ngaphambi kokusebenzisa inkinobho yokulawula ukuvala.
2. Inqubo yokuvula imi kanje:
a. Ngemva kokushintsha ibhodi leziyalezo ebhodini le-analog nebhodi leziyalezo esibambini seswishi yokulawula, sebenzisa iswishi yokulawula ukuze unqamule isinqamuli sesifunda.
b. Ilokhi ye-electromagnetic ivuliwe ngemva kokuvulwa kwe-circuit breaker.
3. Uma ibhasi elikhulu noma ulayini ongenayo ohamba phezulu ubukhoma, i-circuit breaker ingalungiswa ngaphandle kokuhluleka kwamandla.
Okokuqala, vula i-circuit breaker, unqamule futhi ukhiphe wonke ama-circuit breaker wekhabhinethi engenayo, i-circuit breaker ihlukaniswe ngokuphelele nomugqa ophilayo, bese uvula iminyango ephakathi nendawo ephansi ukuze ungene ekamelweni le-circuit breaker ukuze ulungise i-breaker circuit. (Ungawuvuli lo mnyango uma ukukhanya kwenkomba yedivayisi yokubonisa ene-voltage ephezulu kumnyango ophansi kukhanya)
4. I-circuit eyinhloko ayicishiwe, futhi isifunda esisizayo siphelile.
Igumbi lokudlulisa kanye negumbi lokugcina lekhabhinethi yokushintsha lihlukaniswe ngokuphelele nesifunda esikhulu, ngakho-ke isifunda esisizayo singahlolwa futhi silungiswe ngaphandle kokuhluleka kwamandla kumjikelezo omkhulu.
5. Ukuvula izimo eziphuthumayo
Lapho isifunda esiyinhloko sisebenza futhi ukusebenza kuthinteka ukwehluleka kwe-interlock kagesi, idinga ukuvulwa esimweni esiphuthumayo, inqobo nje uma ukhiye wokuvula izimo eziphuthumayo usetshenziselwa ukuwuvula, futhi iminyango ephakathi nendawo ephansi ingavulwa ngokukhululekile. Ngemva kokuba ingozi isiqediwe, kufanele ibuyiselwe esimweni sayo sasekuqaleni ngokushesha. Ukugcinwa kwansuku zonke kufanele kugcinwe ngemuva kokuthi kusetshenziswe, futhi ukushisa kwebhasi kufanele kubhekwe njalo. Uma izinga lokushisa liphezulu kakhulu noma kunomsindo ongajwayelekile, imbangela kufanele iphenywe. Ngokuya ngendawo yokusebenza, umsebenzi wokuhlanza nokunakekela uzokwenziwa njalo eminyakeni emi-2 kuya kwemi-5.
