Laela terata le terata (phapano ke efe?)
Tse ka hare
Ka matlong, mela e 'meli e tsoa ho mithara: lithapo tse sebetsang le tse sa jeleng paate. Mohala o sa nke lehlakore o lula o hokahane le lefats'e mme mohala o phelang o kena ka lebokoseng la fuse (SFU). Ha sesebelisoa se seholo se buletsoe, matla a motlakase a lekanang le zero fatše a sebelisoa ho terata ea mojaro 'me mojaro o hula matla.
Hase kamehla ho leng bonolo ho khetholla lithapo tsa mohala ho tloha methapo ea mojaro. Joaloka moenjiniere ea nang le phihlelo ea motlakase, ke tla u thusa ho utloisisa phapang pakeng tsa lithapo tsa mojaro le lithapo ka ho sebelisa maqheka a seng makae a bonolo. Ho tseba sena, o ka qoba ho khutlisetsa polarity ea mojaro le lithapo tsa mohala, tse ka lebisang ho ts'oenyeho ea motlakase.
U ka khetholla terata ea mojaro ho tloha mohala oa mohala oa potoloho ka ho nahana ka lintlha tse latelang:
- Ho beha mohala
- Likhoutu tsa mohala
- Boholo ba terata
- Tekanyo ea matla a motlakase (V) le a hona joale (A)
Ka tlase re cheka ho teba.
Metheo ea Lithapo Tsa Mojaro le Lithapo (Motlakase).
Ho bohlokoa haholo ho tseba mantsoe "line" le "mojaro" mabapi le sesebelisoa se le seng.
Mohala oa Mohala
Hang ha motlakase o fihla setsing, likhokahano tsa mohala li li fetisetsa ho tloha ho marang-rang a lisebelisoa ho ea setsing sa motlakase. Joale matla a lebisitsoe ho lisebelisoa tsa potoloho ka likhokahano tsa mojaro. Tabeng ena, lithapo tsa mojaro tse tsoang phanele li sebetsa e le likhoele tsa mohala oa sesebelisoa.
Laela terata
Mohala oa sesebediswa ke terata ya sesebediswa se seng tlase ho noka. Ha u hlahloba potoloho, sena se ka baka mathata; ka hona, ho na le matšoao a 'maloa a ho khetholla lithapo tse phelang ho tloha ho li-wiring tse phelang.
Ho etsahala'ng ha u fetola polarity?
Kahoo, sesebelisoa se seng le se seng sa potoloho se tlameha ho ba le matšoao a mela le mojaro ho netefatsa hore ho na le khokahanyo e nepahetseng. Leha ho le joalo, lisebelisoa tse ling, phetoho ea likhokahano tsena e ka ba nyane.
Pole e le 'ngoe, phetoho ea boemo bo le bong e sebetsa hantle le ha e hokahane ka morao. Leha ho le joalo, kaha likhokahano tsa li-terminal li-switches tse nang le maemo a mangata li lebile, li ke ke tsa sebetsa ka katleho haeba li ka khutlisoa.
Boemong bofe kapa bofe, ho khutlisa polarity ho baka kotsi ea ho ts'oaroa ke motlakase, potoloho e khuts'oane kapa mollo. Lebaka ke hobane ka mor'a ho fetoha ha polarity, sesebelisoa se tla lula se le matla le haeba sesebelisoa se tingoa.
Mojaro ha o bapisoa le lithapo tsa mohala
Likopano tse 'maloa li amohetsoe indastering ho khetholla pakeng tsa likhoele tsa mohala le mojaro ho thibela litlamorao tse sa lebelloang tsa ho fetoha ha polarity ho lithapo tsa motlakase. Mona ke tse ling tsa li-parameter tse sebelisoang ho khetholla lithapo:
1. Ho beha mohala
Khokahano ea lithapo tsa mohala ho phanele ea motlakase kapa switch hangata e etsoa ho tloha tlase. Lithapo tsa mojaro li kena ho tloha holimo. Ho feta moo, lintlha tsena tsa khokahanyo ea mohala le mojaro li ngotsoe ho bontša hore na li reretsoe mofuta ofe oa terata.
2. Likhoutu tsa mebala
Likhoutu tsa mebala li sebelisoa likhokelong tsa motlakase ho khetholla mefuta e fapaneng ea lithapo. Ka mokhoa o ts'oanang, likhoutu tsena lia fapana ho ea ka linaha. Linaheng tse ling, botšo bo bontša lithapo tsa mela/uplink ’me bofubelu bo bontša lithapo tsa mehala. Ho feta moo, linaheng tse ling li-screws tsa terminal ka 'ngoe li na le mebala. Ka lebaka leo, hoa hlokahala ho tseba ho ngola mebala e khethehileng sebakeng.
3. Boholo ba mohala
Hobane lisebelisoa hangata li fokotsa voltage kapa hona joale, matla a tsamaisoang holim'a mohala oa mohala o feta oa terata ea mojaro. Lithapo tsa mela hangata li kholo ho feta lithapo tsa mojaro. Sena ke 'nete haeba phapang ea matla e le kholo. Ho ba sieo ha phetoho ea motlakase kapa hona joale ho lisebelisoa tse joalo ka li-overload kapa tšireletso ho etsa hore mokhoa ona o se ke oa sebetsa.
4. Tekanyo ea litšobotsi tsa matla
Hobane matla a motlakase a hlahisoang ke sesebelisoa a le ka tlase ho tlhahiso ea ona, ho lekanya motlakase kapa hona joale lipheletsong tsena ho ka thusa ho khetholla pakeng tsa mohala le mehala ea mojaro. Ho phaella moo, mekhoa e sa tsitsang ea ho lekanya mekhahlelo ena e fanoa ke lisebelisoa tse kang voltmeter / pene le multimeter ea digital. Ha o kopana le sekoti sa terminal kapa terata e se nang letho, neon screwdriver e ka sheba liparamente tsena.
Lisebelisoa tsa GFCI
Likotsi tsa ho khutlisa mela le likhokahano tsa mojaro li tšohliloe likarolong tse fetileng tsa sengoloa sena.
Haeba u belaella phetoho ea polarity, tima motlakase ka kamoreng kapa phaposi hang-hang. Ebe, u sebelisa sehlahlobi se tloaelehileng sa outlet le chate ea voltage, etsa bonnete ba hore phallo e hoketsoe ka nepo. Haeba mohala o sa kopane ka nepo, sesebelisoa se bonolo sa terata se rarolla bothata. Ka bomalimabe, ona ke mokhoa o sebetsang o sieang lisebelisoa le batho ba le kotsing ea ho khutlisa likotsi tsa polarity. Joale ho qala ho sebetsa mabenkele a "ground fault circuit breaker" (GFCI):
Kamoo GFCI e sebetsang kateng
Ho fapana le fuse e sireletsang lisebelisoa, GFCI e hahiloe ka har'a sephutheloana 'me e felisa kotsi ea ho tsosoa ke motlakase. E lula e lekola phallo ea hajoale mme e e sitisa neng le neng ha ho e-na le spike. Ka lebaka leo, e sireletsa khahlanong le liphoso leha e le life tse tsoelang pele.
Ho sireletsa phallo ena le libaka tse ling tse tlase ho potoloho, ho hlokahala khokahano ea GFCI ho liteishene tsa mohala le tsa mojaro. Reverse polarity e ka boela ea hlaha ka har'a lisebelisoa tsa GFCI. Ka lebaka leo, khokahanyo e nepahetseng ea mohala ho mojaro sebakeng seo ke ea bohlokoa bakeng sa polokeho ea libaka tsohle tse tlase ho potoloho ea motlakase.
Sheba tse ling tsa lingoliloeng tsa rona tse ka tlase.
- Ke terata efe e eang ho sekoti sa koporo
- terata ea mojaro ke 'mala ofe
- Mokhoa oa ho pola lithapo tsa motlakase
