Current umehluko. machine umahluko: iimpawu, injongo

Ukuqonda lula na umahluko okhoyo kufuneka ingqalelo inkqubo emzimbeni. Xa kukho touch le igqunyiwe nokuqhutywa umendo, kutheni kungekho kukukhabise ngombane? Impendulo izicacele: bodwa kuthintela flow ezikhoyo emzimbeni womntu. Kodwa ukuba umqhubi ebalelelwe lilanga, kuqalisa zeendawana ubushushu uthinte wire? Isiphumo iyafana - akukho yabanjwa ugesi. Le zeendawana akuthethi ukutshixa beesekethe ngawo umzimba emhlabeni.

Ingcamango ekhoyo umahluko

Kwindalo kukho inkqubo emzimbeni ezifana umehluko yangoku. Lo mqondo a ubuninzi yomzobo, wavakalisa njengoko inani imisinga ezikhoyo kwisekethe, ezithatyathwe ingqiqo yembutho abangenagama. Ukuze wabonakala zahlula lwangoku, inkqubo ngokwasemzimbeni lifika, ekuthiwa ukuvuza yangoku. Kodwa kuyimfuneko ukuba zithotyelwe imeko omnye: isakhiwo isixhobo, apho kwakukho ukuvuza yangoku izakudityaniswa kubekanye emhlabeni. Kungenjalo, ukuba umzimba nisekelwe, ngoko ke isenzeko ukuvuza ngoku kubangela umahluko okhoyo. Kwaye lentsalela full zeesekethe yangoku (RCD) ayisebenzi.

Unxibelelwano phakathi umahluko kunye ukuvuza yangoku

Xa ukuvuza ngoku kwenzeka kwisekethe, ukuba uyaqhubeka iziqalelo kokuba umbandela conductive (housings zesinyithi ezisetyenziswa izixhobo, imibhobho zokufudumeza, njl) Ukususela iindawo phantsi ombane (iisekethe zombane, iingcingo). Ngexesha ezi sayithi elifutshane-ukuvuza abanazo. Ke ngoko akukho nento le iintshukumo zokwaphulwa kwemithetho yokusebenza yesekethe (kwakuba sobala sisilonda esidumbileyoesingaphakathi).

Ekubeni umahluko ngoku xa idlulisa ngokwezibalo imela umahluko (ixabiso kumda wesangqa) phakathi zangoku kwi mthombo imveliso ekhoyo kwaye emva kokuba umthwalo, siyaqondakala ukuba phantse twatse kule ukuvuza yangoku. Kodwa ukuba umntu lowo ukho ngokwenene waphula umthetho, ezifana yokugquma, indawo ephakamileyo ukufuma, awangqinelwa ngawo unokuwisa, okanye into ethile eyenye, umahluko okhoyo livela xa uxhulumaniso kunye nomhlaba.

Nokukhubeka and non-nokukhubeka kwemisinga umehluko

Phantsi nokukhubeka yangoku (okanye nokukhubeka) uqonde umahluko flow okhoyo olubangela Leaks kokuqhawulwa VDT kwi kwikhonkco.

I-flow yangoku leyo kuvumelekile kwisiphaluka isixhobo (RCD) kunye actuation yayo lungenzeki kuthiwa zahlula-non-nokukhubeka ngoku.

Umphathi wesekethe zilayishwe ukuqesha isixhobo ukubetha-type: rectifiers, izixhobo digital obubobu ukuba ulawulo lwamandla - zonke izixhobo zale mihla, ubukho imisinga background umahluko. Kodwa ezi imisinga akukho imisinga umonakalo, kunye yombane kulo mzekelo awucimeki. Ngoko ke, i-RCD umbundu nokukhubeka ikhethiwe efana ukuba i modem ayisebenzi ixabiso yokusebenza ye imvelaphi, kwaye ukucima yangoku ukuvuza ngaphezulu eli xabiso.

RCD okanye Machine umahluko

, Ukuze kukhuselwe wesekethe nxamnye imisinga umhlaba nandzu ubungakanani ezinkulu aba ekhethekileyo breakers beesekethe. isixhobo Driving ngokuqhubekayo livavanya wesekethe ezilawulwa ngenxa ukuvuza sombane. Xa inani kumda wesangqa ye amaxabiso imisinga iya kuba libengaphezulu kunonothi kwaye engena umda bangabonwa, ngoko nangoko vala wesekethe. Iinkqubo olunjalo kunye Imigca-lesigaba ontlantlu-ntathu.

Iimpawu eyenziwayo umehluko

Izilungiso Various izixhobo zokhuselo kwahluka enye kwenye:

• iimpawu zoyilo;
• kuthetha ukuvuza umbane;
• izilungiselelo uvakalelo;
• isantya.

Ngokuxhomekeke kuyilo iimpawu zezi:

• isixhobo VDT (iswitshi umahluko), apho kungekho zokuzikhusela kwemisinga eziphakamileyo. Abasabela kukuvuza imisinga, kodwa ukukhusela icebo labo, gqolo kufuneka ibandakanye iifyuzi.
• RCBOs izixhobo apho kubonelelwe oluzenzekelayo uhlobo iswitshi. Ezi zizixhobo jikelele kunye umsebenzi ezimbini - ukukhusela nxamnye wesekethe elifutshane ukucima kombane, kwakunye nolawulo ukuvuza.
• BDT isixhobo ne ngomatshini kwilori kunokwenzeka abakwindawo udibaniso. Le fowuni ilungiselelwe ukuba ifakwe kunye ungumgqithi wesekethe. design kwayo wasebenza ngendlela yokuba uvumela kuphela ngexesha elinye-uqhagamshelwano kumatshini.

Kuxhomekeka imilo imisinga ukuvuza zikhuliswe izixhobo iqela zokhuselo ezilandelayo zokulungisa:

• AC - izixhobo ezisebenza kunye alternating current sinusoidal. Abayi musa ukuphendula umehluko imisinga ukubetha ezenzeka mzuzu xa, umzekelo, ezijiko-jiko, wezibane izixhobo X-ray, izixhobo nokuhlawulwa iisignali ulwazi, converters thyristor.
• A - izixhobo yokukhuseleka eliguquguqukayo rhoqo ifildi yangoku. Musa ukubona peak ukubetha imisinga umehluko ukuvuza. Basebenza zobuchwepheshe ezifana rectifiers, nabalawuli positionally ukuguquka. Nqanda umhlaba ukuvuza umbane idaleka, nto leyo esinecandelo ombane rhoqo.
• B - Iindlela zokusebenza kunye variable, rhoqo kwaye eliguquguqukayo ukuvuza yangoku.

Ubuntununtunu umahluko switsha na ezi ntlobo zilandelayo:

• inkqubo uvakalelo Low ukuba ukhubaze yesekethe contact ngqo.
• Systems kunye uvakalelo oluphezulu-oda. Ukukhusela, ukuba kubekho ukudibana ngqo ukuya kumqhubi.
• Fire-ekulweni inyathelo.

Ngokutsho ixesha elifunekayo lokuba ukusebenza isixhobo:

• isenzo Instant.
• Speed High.
• Injongo jikelele.
• Ukulibaziseka - uhlobo uyakhetha.

ukhuselo yangoku zahlula yamacebo umkhethi Uyakwazi ukukhubaza kuphela inxalenye kwezixhobo, apho yenzekile yempazamo.

Njani residual yangoku full yesekethe

RCD sakhiwa engundoqo ngokohlobo umsesane kunye jiko ezimbini. Ezi engathi ke ncam, into eyenziwe kwicandelo umnqamlezo olunye ucingo kunye nenani amagophe ezifanayo. Emva nokuphuma elinye lale zangoku kwi umthwalo igalelo ulwalathiso, yaye ngakumbi ngalo umthwalo ubuyela yesibini jiko. Ekubeni umthwalo ngalinye Kudlula yangoku rated, imisinga uwonke ushwankathelwa kule igalelo kwaye imveliso ye Kirgofu linokulingana. Ngenxa yoko, imisinga kwi engathi kudala wobhobhozayo magnethi efanayo ngqo kwicala elahlukileyo. Ezi nokuphuma lulungisa omnye komnye kunye nenkqubo uhlala kwi imeko enye. Ukuba kuphela kukho ukuvuza ngoku, lo mhlaba otsalayo iya kuba ezahlukeneyo, kuya kusebenza lo umahluko relay lwangoku, nto leyo eya kukhokelela yokuvulwa abafowunelwa zombane. Umgca sombane uya ngokupheleleyo de-amandla.

Apho ukhuseleko esebenzayo isixhobo intsalela yangoku

Xa zokwakha mihla kunye neendawo izixhobo zombane, kwakunye zilungiswe izixhobo ukusetyenziswa kakhulu ukuba yangoku intsalela. Oku sigwetyelwe kukwanda ukhuseleko yokusebenza kothungelwano zombane, kwakunye nokuhla iingozi. RCDs zisetyenziswa:

• izakhiwo zoluntu: izikolo, izakhiwo zenkcubeko, izibhedlele, iihotele, amaziko ezemidlalo;
• Izakhiwo kunye yokuhlala zokuhlala ngamnye: izindlu, nemiqolomba, iihostele, izakhiwo encedisayo;
• nendawo yokuthengisela, ingakumbi unokwenziwa usekelwe izakhiwo yesinyithi;
• izakhiwo ukulungiselela iinjongo zolawulo;
• amashishini industrial.

ongakhetha Connection schemes RCD

Zahlula isixhobo yangoku yokhuselo ukuvelisa inani ezahlukeneyo izigaba esweni. Kukho omnye sigaba, isigaba-mbini kunye ontlantlu-ntathu eyintsalela circuit breakers yangoku.

Ukuba umgca kwisigaba esinye kwaye kufuneka adityaniswe kuyo kwaye RCD olunye umaphuli wesiphaluka, nto ayenzi mahluko kwi siseko, yintoni ukubeka kwindawo yokuqala. Zonke ezi zixhobo zibekwe kwigalelo wesekethe. Nje lula kakhulu ukuba kwisigaba sokuqala oluzenzekelayo yaye intsalela yangoku umaphuli wesekethe emva. Ekubeni umthwalo ke ngoko idityaniswe zombini abafowunelwa RCD endaweni kwesigaba - kulo matshini, endaweni ka-zero - kwifowni yokhuseleko.

Ukuba umgca engundoqo yohlulwe imigca eziliqela imithwalo, i-RCD wabeka kuqala, uze emva koko ngenxa kumgca ngamnye ungumgqithi wesiphaluka. Kubalulekile ukuba yangoku rated elingase kudlule le RCD, waba elide yokusebenza umatshini ngoku, kungenjalo kuba nako ukukhusela ifowuni ngokwalo.

isiphelo

Wonke umsebenzi kwi intlangano lweenkqubo zokukhusela kweentambo zombane kunye beesekethe kungcono wombane professional! kuwe kuphela ndawonye ngezandla zabo elula eesekethe zombane kunye nezihlanganisi izixhobo zokhuseleko, ukulandela ngqo le miyalelo. Ngokuqhelekileyo, qhagamshelana nganye inkampani ahambelanayo.
