Matla Phepelo Tšireletso

Matla Phepelo Packages

Ho na le litšobotsi tse ling tse 'maloa hore tshusumetso matla-phepelo tshebetso. Har'a tsona ke tseo hiriloe ho sireletsa phepelo ea, tse ho tse thathamisitsoeng mona ka tlase.

Overcurrent : A mokgwa wa ho hloleha bakoang ke khumo mojaro jwale hore o moholo ho qoolloa. E lekanyetsoeng ke nako e lebetsoeng le bokgoni jwale ya phepelo matla le laoloa ke lipotoloho tšireletso ea ka hare. Ho ka boetse ha senya phepelo matla maemong a mang. Short lipotoloho pakeng tsa matla-phepelo khumo le fatše ka bopa maqhubu ka hare ho tsamaiso ea hore ba felle feela ka ho ba palo e kahodimodimo bokgoni jwale le impedance hare tsa phepelo le matla a. Ntle le ho fokotsa, sena hona joale phahameng ka etsa hore overheating le ho senya phepelo matla hammoho le mojaro le interconnects lona (mesaletsa hatisitsoeng oa potoloho boto, lik'hebole). Ka lebaka leo, a fanang ka ho fetisisa matla ba lokela ho ba hona joale fokotsa (overcurrent tšireletso ea) hore activates haeba khumo jwale feta e boletsweng lebetsoeng le.

Overtemperature:  A mocheso le ka holimo ho boletsweng boleng le phepelo ea matla a tlameha ho thibela kapa e ka etsa hore matla-phepelo hloleha. Ka tsela e feteletseng ho sebelisa mehaho mocheso ho ka senya le phepelo matla le lipotoloho amanang ho eona. Ka lebaka leo, a fanang ka tse ngata ba sebelisa e le kutlo mocheso le lipotoloho se amahanngoang ho go tima phepelo ea ha ho sebelisa mehaho lona mocheso feta ka boleng ba itseng. Ka ho khetheha, semiconductors sebelisoa ka phepelo ea tse kotsing ea ho mocheso ho ka nģ'ane ho meeli ea bona boletseng. A fanang ka tse ngata ho kenyeletsa tshireletso ya overtemperature hore fellang kateng theoha phepelo ea ha mocheso leta boletsweng moedi.

Overvoltage:  ena mokgwa wa ho hloleha ho etsahala haeba khumo gagamalo tsoela ka holimo ea boletsweng boleng dc, e leng se ka lefisa ka tsela e feteletseng dc gagamalo hore ho senyeha le lipotoloho mojaro. Ka tloaelo ho, ea elektronike oona tsamaisong mejaro ka mamella ho fihlela ho 20% overvoltage ntle ho ipokellela tshenyo efe kapa efe ka ho sa feleng. Haeba ena ke ho nahanela, kgetha phepelo hore kokitisa kotsi ena. A fanang ka tse ngata ho kenyeletsa tshireletso ya overvoltage hore fellang kateng phepelo ea theoha haeba khumo gagamalo feta e boletsweng tshelete. Wa katamelo e mong ke crowbar zener diode hore o khanna hona joale ka ho lekaneng lintšing overvoltage e le hore e activates le matla-phepelo jwale fokotsa le hore a mo koalla fatše.

Bonolo Qala:  Inrush moedi jwale 'na ha hlokahala ha matla a pele sebelisoa kapa ha mapolanka a macha a chesang e thijoe. Ka tloaelo, sena se fihleloa ka ho sa bonolo-simolleng oa potoloho hore, ae fokotsang lebelo le ho phahama pele ea morao-rao ebe dumella tshebetso tloaelehileng. Ha setseng untreated, ho inrush jwale ka hlahisa le tlhōrō e phahameng lefisa jwale hore tshusumetso le khumo gagamalo. Haeba ena ke ho nahanela bohlokoa, kgetha phepelo le tšobotsi ena.

Undervoltage Lockout:  Tsejoang e UVLO, ho fellang ka phepelo ka ha e fihla phahameng lekana input gagamalo le fellang kateng theoha phepelo ya haeba input gagamalo oela tlase ya boleng itseng. Tsobotsi ena e sebediswa bakeng sa phepelo ea sebetsa ho tloha matla utility hammoho le matla a leshala. Ha sebetsa ho tloha matla leshala thehiloeng UVLO disables phepelo matla (hammoho le tsamaiso) haeba leshala lutla hoo ho marotholi phepelo e input gagamalo tlaase haholo ho lumella tshebetso ka tšeptjoang.

Motlakase sa tshebeletsano (EMC):  akarelletsa dithekeniki moralo hore fokotsa motlakase tshitsiso (EMI). Ka phepelo switjha-mokgwa wa matla a, e leng dc gagamalo e fetoloa ho hasesaane kapa la modumo pulsed. Sena se etsa hore phepelo ea matla a ho hlahisa lerata moqotetsane-sehlopha (EMI) ka motheo oa ho switjha maqhubu le harmonics lona amanang. Ho na le lerata la, bahlahisi lokela ho fokotsa radiated kapa khanna mesi e kotsi.

Matla-phepelo bahlahisi fokotsa EMI mahlaseli ke ea kenyelletsa phepelo ka lebokose tšepe kapa spray bitiela ka taba ka lintho tse bonahalang metallic. Manufacturers boetse ho hlokahala ho lefa a lebisa tlhokomelo ho moralo ka hare tsa phepelo le wiring hore tsoela kena le ho tsoa phepelo, e leng ka hlahisa lerata.

Boholo ba tshitsiso khanna moleng matla ke phello ea ho ba ka sehloohong ho switjha transistor kapa khumo rectifiers. Le matla-le palokatiso khalemelo le e loketseng transformer moralo, mabapi tsa mocheso teba, 'me filtara moralo, le matla-phepelo moetsi ka fokotsa khanna tshitsiso e le hore phepelo e ka finyella EMI taolo mokhatlo o fanang ka ditumello ntle ho ipokellela ka tsela e feteletseng theko filthara. Kamehla hlahloba ho bona e le hore matla-phepelo moetsi kopana le ditlhoko tsa taolo melao-motheo ea EMI.
