Mokhoa oa ho Lekola Phetoho ea Leseli ka Multimeter (Setataiso sa Mehato e 7)

Batho ba sebelisa li-switches tsa bona tsa mabone ka makhetlo a likete selemo se seng le se seng. Ke ntho ea tlhaho hore li khathale kapa li senyehe ha nako e ntse e ea. Ha ho hlokahale hore u tšoenyehe haeba u nahana hore u na le sesebelisoa sa lebone se fosahetseng.

U na le khetho ea ho letsetsa setsebi sa motlakase kapa ho itlhahloba ka bouena. Ke tla o ruta tsa morao.

Ka lehlohonolo, ho bonolo ho leka sesebelisoa sa lebone haeba u na le lisebelisoa tse nepahetseng.

Lisebelisoa tseo u li hlokang

U tla hloka tse latelang:

• Mohloli oa motlakase o sa amaneng le motho
• Screwdriver
• Multimeter
• Theipi e sireletsang

Mohato oa #1: Ho tima

Koala sekhechana sa potoloho se nepahetseng ho switchboard e kholo ea lehae la hau ho khaola motlakase ho sekhechana sa lebone. Haeba u lula ntlong ea khale e nang le phanele ea fuse, tlosa fuse e ts'oanang ka botlalo ho sokete ea eona.

Kamehla hlahloba khokahanyo ea motlakase pele u khaola lithapo le ho tima switch, hobane index panel ea litšebeletso kapa li-circuit labels hangata li ngotsoe hampe.

Mohato oa #2: Sheba Matla

Lokolla liboutu tsa sekwahelo 'me u tlose sekoaelo ho pepesa terata ea switjha. Sebelisa mochine o hlahlobang motlakase o sa amaneng le batho ho leka terata e 'ngoe le e 'ngoe e phaneleng ea motlakase ntle le ho e ama.

Hape, hlahloba li-terminals tsa mahlakoreng a switjha ka 'ngoe ka ho li ama ka ntlha ea teko. E-ea phanele ea lits'ebeletso ebe u tima switch e loketseng haeba metara e bona voltage leha e le efe (e khantša kapa e qala ho buzz), ebe u pheta ho fihlela motlakase o fumanoa.

Mohato oa #3: Lemoha mofuta oa switjha

Mefuta e fapaneng e kenyelletsa:

1. switjha ya palo e le 'ngoe
2. Liphetoho tse tharo tsa maemo
3. Phetoho ea maemo a mane
4. Dimmer
5. Phetoho ea ho ba teng
6. Smart Switch

Taba ea hore li-switches li tla ka mefuta e fapaneng e lokela ho tsotelloa ha ho hlahlojoa. Ke ka lebaka lena re tlamehang ho qala ka ho tseba hore na re sebetsana le mofuta ofe.

Ho na le mekhoa e 'maloa ea ho tseba hore na u na le switch ea lebone ea mofuta ofe:

1. Sheba switjha ka boeona.: Sesebelisoa se tlameha ho tšoauoa kapa ho ngoloa ho bontša mofuta oa sona, joalo ka "palo e le 'ngoe", "maemo a mararo" kapa "dimmer".
2. Bala palo ea lithapoTlhokomeliso: Li-switches tse nang le palo e le 'ngoe li na le lithapo tse peli, ha tse tharo le tse 'nè li na le tse tharo. Li-switches tsa dimmer li ka ba le lithapo tse eketsehileng, ho latela mofuta.
3. Sheba SwitchA: U ka e leka ho bona hore na e sebetsa joang. Ka mohlala, sesebelisoa se le seng sa palo se tla laola lebone kapa sesebelisoa se seng sa motlakase ho tloha sebakeng se le seng, ha sesebelisoa sa maemo a mararo se tla u lumella ho khantša kapa ho tima lebone libakeng tse peli.

Mohato oa #4 Tima 'me u Nchalle Switch

Tlosa lithapo ka ho lokolla li-screws tsa theminale. Sena se tla emisa switch.

Beha switch sebakeng sa mosebetsi ho e leka. Pele o tlosa li-switches tse khanyang, o ka li hloekisa.

Mohato oa #5: Etsa Tlhahlobo ea Tsoela Pele ea Switch

Ho etsa sena, o tla hloka continuity tester. Ka lehlohonolo, sena se ka khoneha le ka multimeter. 

Teko ea ho tsoela pele e fapana ho latela mofuta oa switjha. Ka hona, re li arola ka mekhahlelo mme ra hlalosa e 'ngoe le e' ngoe ka thoko:

switjha ya palo e le 'ngoe

Pele, nka tester 'me u kopanye e' ngoe ea lithapo ho terminal. Nka probe 'me ue khomarele ho terminal e' ngoe. Ho bulela tester, tobetsa switjha.

Haeba e bonesa, ho bolela hore switch e maemong a matle ebile e sebetsa hantle. Se fapaneng se bontša hore switjha e fosahetse. Tlosa switch ea lebone haeba sena se etsahala.

Liphetoho tse tharo tsa maemo

Hokela black lead ea continuity tester ho terminal ea com. Karolo ena e tšoana le ea pele. Ka mor'a moo, hokela probe ho terminal ea moeti. Multimeter e lokela ho sebelisoa ho lekanya voltage.

Sheba hore na lebone lea buleha ha switch e buletsoe. Sheba terminal e 'ngoe haeba ho le joalo. Ha e nepahale ntle leha ka bobeli ba bonesa. Tlosa sensor ea overrun 'me u e nkele sebaka ka e ncha.

Phetoho ea maemo a mane

Li-switches tsena li na le li-terminals tse 'nè. E ka ferekanya ka linako tse ling, empa eseng thata haholo. Seo u se hlokang feela ke tlhokomelo e nyane.

Taba ea pele, hokela letoto la tlhahlobo ho terminal e hoketsoeng e lefifi. Mohala o mong o hoketsoe hantle ho terminal e nang le khoele e nyane. Bulela le ho tima switch.

Bakeng sa boemo bo le bong u tla ba le ts'ebetso. Haeba u bona ka bobeli kapa che, e kanna ea se be e nepahetseng haholo. Hokela ho li-terminals tse ling 'me u phete mokhoa ona ha u qetile.

Lekhetlong lena o lokela ho fumana tsoelo-pele sebakeng se fapaneng. Haeba e sa etse joalo, switjha e ka 'na ea e-ba le phoso. Haeba u fumana boleng bo fapaneng, fetola switch.

Mohato oa #6: Tlosa sebaka kapa u hokahane hape

Hokela lithapo tsa potoloho ho switjha. Ebe, tiisa li-screw terminals le li-screw tsa fatše ka thata.

Haeba u fetola switch, latela mehato e tšoanang. Etsa bonnete ba hore hona joale le voltage li lekana. Ha o qetile, khutlisetsa tsohle moo li neng li le teng.

Mohato oa #7: Qetella Mosebetsi

Kenya switch hape, kenya lithapo ka hloko ka har'a lebokose la mateano, 'me u hokele thae ea switjha lebokoseng la mateano ka liboutu tse ntseng li holisa kapa li-screw. Kenya sekoahelo hape. 

Ka mor'a ho tsosolosa fuse kapa ho tsosolosa mochine oa potoloho, tsosolosa matla ho potoloho. Sheba hore na sesebelisoa se sebetsa hantle. (2)

Mefuta e tloaelehileng ea phetoho:

1. Single Pole Switch: Ona ke mofuta o atileng haholo oa switch ea mabone. E laola lebone kapa lisebelisoa tse ling tsa motlakase ho tloha sebakeng se le seng, joalo ka sesebelisoa sa lebota ka phapusing.
2. Phetoho ea maemo a mararo: Sesebelisoa sena se sebelisoa potolohong e nang le mabone a mabeli a laoloang ke li-switches tse peli. E u lumella ho khantša le ho tima lebone ka sesebelisoa leha e le sefe.
3. Four Position Switch: Sesebelisoa sena se sebelisoa potolohong e nang le mabone a mararo kapa ho feta a laoloang ke li-switches tse tharo kapa ho feta. E u lumella ho khantša le ho tima lebone ka sesebelisoa leha e le sefe sa potoloho.
4. Dimmer Switch: Mofuta ona oa switjha o u lumella ho fokotsa leseli ka ho theola switch holimo kapa tlase. Hangata e sebelisoa ka kamoreng ea ho phomola le likamoreng tsa ho robala.
5. Timer Switch: Sesebelisoa sena se etselitsoe ho khantša kapa ho tima lebone kapa sesebelisoa se seng sa motlakase ka nako e itseng. E ka sebelisoa ho iketsetsa mabone ka tlung kapa ofising.
6. Presence Sensor Switch: Sesebelisoa sena se bonesa lebone ha se bona motsamao ka phaposing ebe oa le tima ha ho se ho sa sisinyehe. Hangata e sebelisoa matlong a phomolo a sechaba, litepising le libakeng tse ling moo leseli le ka siuoang ho sa hlokahale.
7. Remote Control Switch: Sesebelisoa sena se u lumella ho khantša le ho tima lebone ka remote control. Sena se ka thusa li-switches tse thata ho fihla kapa ho laola mabone a mangata ka nako e le 'ngoe.
8. Smart Switch: Mofuta ona oa switjha o ka laoloa hole o sebelisa sesebelisoa sa smartphone kapa bathusi ba lentsoe joalo ka Google Assistant kapa Amazon Alexa. E ka boela ea hlophisoa ho khantša le ho tima mabone ka linako tse itseng kapa ho ipapisitse le lintho tse ling tse ka etsang hore letsatsi le chabe kapa le likele.
