Kulesi sigaba, izinto zokusebenza zokusabalalisa amandla kanye nohlelo lokuphakelwa kukagesi kanye nokusabalalisa embonini ye-petrochemical ngokuvamile zisebenzisa amandla e-AC ohlelo lokuphakelwa kukagesi lwe-UPS.Ngemuva kokuthi amagatsha amaningi elawulwa futhi acutshungulwe ama-circuit breaker ane-voltage ephansi, akhipha i-24V DC ne-110V AC ngokusebenzisa iziguquli ze-AC/DC noma iziguquli nezinye izinto zokusebenza ukuze zinikeze imithwalo kagesi kumaphaneli ahambisanayo.
I-switchboard (ibhokisi) efakwe embonini ye-petrochemical kufanele ifakwe endlini enezimo ezinhle zemvelo.Uma ukufakwa kwangaphandle kudingekile, izindawo ezinezimo ezinzima kufanele zigwenywe, futhi amabhokisi okusabalalisa (amabhokisi) afanele amazinga emvelo yemvelo yendawo yokufaka kufanele akhethwe.
Ngenxa yezidingo zokukhiqiza, kunenqwaba yemithwalo yepompo embonini ye-petrochemical, futhi imithwalo eminingi yepompo ifakwe iziqalisi ezithambile.Ukusetshenziswa kweziqalisi ezithambile kuqhubeza nokwandisa okuqukethwe kwamanje kwe-pulse yezinhlelo zemishini yokusabalalisa amandla embonini ye-petrochemical.Njengamanje, iziqalisi eziningi ezithambile zisebenzisa izihlungi eziyisi-6 ze-single-pulse ukuguqula i-AC yamanje ibe yi-DC, futhi ama-harmonics aphumayo ikakhulukazi ama-harmonics wesi-5, 7th kanye ne-11.Ukulimala kwama-harmonics kuhlelo lwe-petrochemical system kubonakaliswa ikakhulukazi ekulimaleni kobunjiniyela bamandla kanye nephutha lokulinganisa okunembile.Ucwaningo lwesayensi lubonisa ukuthi imisinga ye-harmonic izodala ukulahlekelwa okwengeziwe kuma-transformers, okungase kuholele ekushiseni ngokweqile, kusheshise ukuguga kwezinto ezivikelayo futhi kuholele ekulimaleni kwe-insulation.Ukuba khona kwe-pulse current kuzokwandisa amandla abonakalayo futhi kube nomthelela omubi obalulekile ekusebenzeni kahle kwe-transformer.Ngesikhathi esifanayo, ama-harmonics anomthelela ongemuhle kuma-capacitor, ama-circuit breaker, kanye nemishini yokuvikela i-relay ohlelweni lwamandla.Kumathuluzi amaningi okuhlola, impande yangempela yevelu yesikwele ayikwazi ukukalwa, kodwa inani elimaphakathi lingalinganiswa, bese i-waveform ecatshangwayo iphindaphindwa ngenkomba ephozithivu ukuze kutholwe inani lokufunda.Lapho ama-harmonics ebucayi, ukufundwa okunjalo kuzoba nokuphambuka okukhulu, okuholela ekuphambukeni kokulinganisa.
Izinkinga ongase uhlangane nazo?
1. Ukuqala izinkinga zama-blower namaphampu ahlukahlukene
2. I-converter ye-frequency ikhiqiza inani elikhulu lama-harmonics, elithinta ukusebenza okuphephile kwemishini kagesi ohlelweni.
3. Izinhlawulo ezingavumelekile ezidalwe isici samandla aphansi uma kuqhathaniswa (ngokuvumelana “Nezilinganiso Zenkokhelo Kagesi Yesici Samandla” ezakhiwe uMnyango Wezinsiza Zamanzi Namandla Kagesi wenkampani yethu kanye Nehhovisi Lamanani Lenkampani yethu).
4. Imboni ye-petrochemical iyinkampani edla kakhulu amandla.Ngenxa yezinguquko kuzinqubomgomo nemithetho yenkampani yethu yokusebenzisa ugesi, ingase ithintwe umehluko ezindlekweni zikagesi.
Isixazululo sethu:
1. Faka isinxephezelo esizenzakalelayo sohlobo lwe-hy-voltage high-voltage isinxephezelo esizenzakalelayo ohlangothini lwesistimu ukuze unxephezele amandla asebenzayo esistimu, uthuthukise isici samandla, uklame izinga lokusabela eliphumelelayo, futhi ulawule ngokuzenzakalelayo ukushaya kwenhliziyo kwesistimu;
2. Uhlangothi lwamandla kagesi aphezulu lwesistimu lusebenzisa isistimu yokutakula okuguquguqukayo kwekhwalithi yamandla ukunxephezela ngamandla imithwalo esebenzayo ngesikhathi sangempela nokugcina ukuthembeka kwekhwalithi yamandla yesistimu;
3. Isihlungi esisebenzayo i-Hongyan APF sifakwe ohlangothini lwe-voltage ephansi engu-0.4kV ukuze kuphathe i-harmonics yesistimu, futhi idivayisi yesinxephezelo sokuphepha esimile isetshenziselwa ukunxephezela amandla asebenzayo esistimu ukuze kuthuthukiswe isici samandla.
