Ekuhlolweni kwangempela nasekuhlaziyeni ikhwalithi yamandla wegridi yamandla, ukuhlaziya ikhwalithi yamandla kuyadingeka.Le divayisi isetshenziswa kakhulu ekukalweni kwekhwalithi yamandla futhi idume kakhulu phakathi kwezisebenzi zamandla kagesi.Kulesi sihloko, i-HV Hipot izonikeza isingeniso esifushane sale mishini
I-HV Hipot GDPQ-300A Power Quality Analyzer
Ikhwalithi yamandla isho ikhwalithi yamandla e-AC anikezwa abasebenzisi ngegridi yomphakathi.Ngokuvamile, kubhekiselwa kukhwalithi yamandla emigqa yegridi.Izinkinga zekhwalithi yamandla zibangelwa ikakhulukazi uhlangothi lomthwalo wetheminali.Isibonelo, umthelela wokulayisha okusebenzayo uzokwenza i-voltage yegridi iguquguquke ngamandla futhi yehlise ikhwalithi yokuphakelwa kwamandla.
Ngokuthuthukiswa kobuchwepheshe be-elekthronikhi, akulethi nje kuphela izici ezinhle zokonga amandla kanye nokuguqulwa kwamandla embonini yesimanje, kodwa futhi kuletha izinkinga ezintsha nezibucayi kakhulu kwikhwalithi yamandla ngenxa yokusetshenziswa okubanzi kwamandla kagesi kuyo yonke imikhakha yempilo.Umonakalo usuphenduke umthombo oyinhloko wokungcoliswa kwe-harmonic wegridi yamandla.Inani lezihlungi, iziguquli zefrikhwensi, iziko likagesi ze-arc, izitimela ezifakwe ugesi kanye nezinto ezihlukahlukene zikagesi neze-elekthronikhi kunethiwekhi yokusabalalisa yabathengi ngabanye ohlelweni lwegridi liyakhula.kuthinte noma kungcolise igridi yamandla.Imbangela ukuntengantenga kwamandla kagesi, ukweqisa kwamandla kagesi, ukukhiqizwa kwe-harmonic, njll. Ama-Harmonics anciphisa ukusebenza kahle kokukhiqizwa kwamandla, ukudluliswa nokusetshenziswa kwamandla, abangela ukuthi okokusebenza kukagesi kushise ngokweqile, kukhiqize ukudlidliza nomsindo, ukwahlukanisa iminyaka, kufinyeze impilo yesevisi, ngisho nokuhluleka noma ukusha.I-Harmonics ingase futhi ibangele i-parallel resonance yasendaweni noma uchungechunge lwe-resonance yesistimu yamandla, ekhulisa okuqukethwe kwe-harmonic futhi ibangele okokusebenza okufana nama-capacitor ukuthi ashise.
Ukungatholakali kwe-linearity, ukushaqeka kanye nezici zokusetshenziswa kwamandla okungalinganiseli zalezi zilayidi kubangela ukungcoliswa okukhulu kwekhwalithi yokuphakelwa kwamandla.Ngakho-ke, ukuqedwa kwama-harmonics asezingeni eliphezulu ohlelweni lokuphakelwa kukagesi nokusabalalisa kunokubaluleka okuhle kakhulu kokuthuthukisa ikhwalithi yamandla nokuqinisekisa ukusebenza okuphephile, okuzinzile nokonga kwesistimu yamandla.Ngakolunye uhlangothi, izinto zikagesi zabasebenzisi besimanje bezimboni, ezentengiselwano kanye nezindawo zokuhlala zizwela kakhulu ikhwalithi yamandla futhi zibeka phambili izidingo eziphakeme zekhwalithi yokuphakelwa kukagesi.Njengamanje, i-harmonics, ukuphazamiseka kazibuthe kanye nokunciphisa isici samandla kufakwe ohlwini njengezingozi ezintathu ezinkulu zomphakathi zohlelo lwamandla.
Uma ikhwalithi yamandla wegridi kagesi iphazamiseka noma ingcoliswa futhi ihluleka ukuhlangabezana namazinga afanele okuthuthukiswa kazwelonke, kuyadingeka ukuthuthukisa ukuphathwa kwekhwalithi yamandla obuchwepheshe begridi yamandla ngendlela ehlosiwe.Ukuze uqonde izimo zokusebenza zangempela zekhwalithi yamandla wegridi yamandla, kuyadingeka ukuba nezinto ezihambisanayo zokuhlaziya idatha yokulawula nokuhlola.Ngokwezimo zokuphila zangempela ezweni lami, inkampani yethu ingathuthukisa ngesikhathi futhi ithuthukise amathuluzi okuhlaziya inkinga yekhwalithi yamandla afanele izimo zethu zezwe.Okulandelayo incazelo enemininingwane yokusebenza okuthile, imingcele, nokusetshenziswa kwale ndlela yokuhlaziya ikhwalithi yamandla.
I-analyzer yekhwalithi yamandla iyithuluzi eliqeqeshiwe elisetshenziswa izisebenzi zamandla kagesi ukuze zihlaziye futhi zihlole ikhwalithi yamandla emsebenzini wangempela.Idume kakhulu phakathi kwabasebenzi bamandla kagesi, ngakho wonke umuntu udinga ukukwazi kahle.
