Taƙaitaccen Gabatarwa game da Aikace-aikacen AHF (Active Harmonic Filter)
1. Menene abubuwan da ke haifar da ƙarfin harmonic da na yanzu harmonic?
Yawan amfani da na’urorin da ba na layi ba (kamar masu canza mitar, rectifiers, da hasken LED) yana haifar da gurbatar harmonic mai tsanani a cikin grid na wutar lantarki, yana haifar da jerin matsaloli kamar zafi mai yawa na kayan aiki, rashin aiki na na’urorin kariya, da raguwar ma’aunin wutar lantarki.
A matsayin sabon ƙarni na kayan sarrafa ingancin wutar lantarki, AHF (Active Harmonic Filter) yana zama kayan aiki na musamman don magance matsalolin harmonic a masana’antu.
2.Manyan halaye na masana’antu:
Idan aka kwatanta da gine-gine na yau da kullun, masana’antu suna da buƙatun wutar lantarki na musamman, wanda ke ƙayyade wajibcin sarrafa harmonic.
Ƙarfin Wuta Mai Girma: Tare da yawan kayan aikin samarwa, nauyin masana’anta ɗaya yakan kai dubbai zuwa dubunnan dubban volt-amperes, yana sa matsalolin wutar lantarki su ƙaru cikin sauƙi.
Iri-iri na Kayan Aiki: Masana’antu sun ƙunshi kayan aiki iri-iri, gami da kayan aikin injina daban-daban, layukan samarwa na atomatik, da kayan aikin wutar lantarki, suna sanya matsin lamba mai yawa akan tsarin wutar lantarki.
Bukatun Dogaro Mai Girma: Samarwa na ci gaba yana nufin cewa sauye-sauyen wutar lantarki na iya haifar da tsayawa aiki, ɓarna samfura, da hatsarori na aminci.
3.Nauyin masana’anta: babban tushen harmonics. Nauyin da ba na layi ba a masana’anta shine tushen haifar da harmonic, kuma ba za a iya yin watsi da cutarwarsu ba.
01. Kayan Aikin VFD (Variable Frequency Drive): Masu canza mitar da ake amfani da su don sarrafa gudun kayan aiki kamar fannoni da famfo suna haifar da adadi mai yawa na harmonics na musamman (5th, 7th, da 11th harmonics) yayin tsarin gyara-juyarwarsu.
02. Kayan Aikin Rectifier: Tankunan electroplating, tsarin UPS, da sauransu, suna shigar da wutar da ba sinusoidal ba a cikin grid na wutar lantarki.
03. Kayan Aikin Arc: Tanderun Arc da injinan walda suna haifar da sauye-sauyen harmonic masu fadi. Yayin farawa da walda, manyan canje-canjen wutar lantarki suna haifar da harmonics da yawa, inda 3rd, 5th, 7th, 11th, da 13th harmonics suka yi fice musamman.
04. Kwamfutoci da Sabobin: Kwamfutoci suna haifar da igiyoyin harmonic yayin farawa da aiwatar da shirye-shirye, suna sanya buƙatu masu yawa akan kwanciyar hankali da ingancin wutar lantarki.
05. Hasken LED: Masu tuki na hasken LED suna nuna halaye marasa layi. A ƙarƙashin daidaitawar haske daban-daban, canje-canjen wuta da ƙarfi ba na layi ba ne, suna iya haifar da harmonics da shafar ingancin grid na wutar lantarki.
4.Haɗarin harmonics sun haɗa da:
Tsufar kayan aiki da sauri: yana sa motoci da tasfoma su yi zafi da yawa kuma yana rage tsawon rayuwarsu. Ƙaruwar asarar wutar lantarki: yana haifar da ƙaruwar asarar layi da kayan aiki da tsadar wutar lantarki. Tsoma baki tare da daidaiton sarrafawa: yana shafar siginonin PLC da firikwensin kuma yana rage daidaiton samarwa.
5.Nazarin Shari’a: Wurin Tanderun Arc na Lantarki a Masana’antar Karfe – Magance Sauye-sauyen Harmonics
Bayanin Aikin: Yayin aiki, tanderun arc na lantarki a masana’antar karfe yana fuskantar walƙiyar hasken wurin aiki da ƙararrawar ƙarya daga tsarin sarrafa PLC, wani lokaci yana haifar da kashe tanderun tare da asarar da ta wuce ¥100,000 a kowane kashewa.
Sakamakon Gwaji: Yayin aikin tanderu, THDi ya bambanta tsakanin 15% da 35%, tare da mitocin harmonic masu rikitarwa waɗanda suka bambanta da matakin narkewa.
Magani: An yi amfani da tacewa mai aiki tare da saurin amsawa na ≤10ms don bin diddigin da rama canje-canjen harmonic a ainihin lokaci.
Sakamakon Aikace-aikace: An sarrafa THDi a cikin kwanciyar hankali a cikin 8%, walƙiyar haske da ƙararrawar ƙarya daga tsarin sarrafawa sun ɓace, kuma ƙimar ci gaba da aiki na tanderun arc na lantarki ta ƙaru daga 85% zuwa 98%.
