Mothating ona, lisebelisoa tsa kabo ea motlakase le sistimi ea phepelo le phepelo ea motlakase indastering ea petrochemical hangata li sebelisa matla a AC a sistimi ea phepelo ea motlakase ea UPS.Ka mor'a hore makala a mangata a laoloe le ho sebetsoa ke li-circuits tsa motlakase tse tlaase, li hlahisa 24V DC le 110V AC ka li-converter tsa AC / DC kapa li-transformer le lisebelisoa tse ling ho fana ka meroalo ea motlakase bakeng sa liphanele tse lumellanang.
Switchboard (lebokose) e kentsoeng indastering ea petrochemical e lokela ho kenngoa ka tlung e nang le maemo a matle a tikoloho.Haeba ho hlokahala ho kenngoa ka ntle, libaka tse nang le maemo a thata li lokela ho qojoa, 'me mabokose a kabo (mabokose) a loketseng maemo a tlhaho a sebaka sa ho kenya a lokela ho khethoa.
Ka lebaka la litlhoko tsa tlhahiso, ho na le meroalo e mengata ea lipompo indastering ea petrochemical, 'me meroalo e mengata ea pompo e na le lisebelisoa tse qalang tse bonolo.Tšebeliso ea li-starter tse bonolo le ho feta e eketsa litaba tsa morao-rao tsa lisebelisoa tsa kabo ea matla indastering ea petrochemical.Hajoale, li-starter tse ngata tse bonolo li sebelisa li-rectifiers tse 6 tsa single-pulse ho fetolela AC hona joale hore e be DC, 'me li-harmonics tse hlahisoang ke haholo-holo tsa 5th, 7th le 11th harmonics.Kotsi ea li-harmonics ho software ea petrochemical system e bonts'oa ka ho khetheha kotsi ea boenjiniere ba matla le phoso ea tekanyo e nepahetseng.Liphuputso tsa saense li bontša hore maqhubu a harmonic a tla baka tahlehelo e eketsehileng ho li-transformer, tse ka lebisang ho futhumala ho feteletseng, ho potlakisa botsofali ba thepa ea ho itšireletsa le ho lebisa tšenyo ea ho pata.Ho ba teng ha pulse hona joale ho tla eketsa matla a bonahalang 'me ho be le phello e mpe e kholo ho katleho ea transformer.Ka nako e ts'oanang, li-harmonics ka kotloloho li na le phello e mpe ho li-capacitor, li-circuit breakers, le lisebelisoa tsa ts'ireletso ea relay tsamaisong ea matla.Bakeng sa lisebelisoa tse ngata tsa tlhahlobo, motso oa 'nete o bolelang boleng ba lisekoere o ke ke oa lekanyetsoa, empa boleng bo tloaelehileng bo ka lekanyetsoa,' me joale sebopeho se inahaneloang sa maqhubu se atolosoa ke index e ntle ho fumana boleng ba ho bala.Ha li-harmonics li tebile, ho bala ho joalo ho tla ba le liphapang tse kholo, e leng se tla fella ka ho kheloha ha litekanyo.
