Labelling oluseduze. Izinhlobo, izici nenjongo amadlambi

Kuqhathaniswa ezivamile wesifunda amadlambi lungaphansi amakhabethe enzelwe ukuvikela wiring avela ezifundeni ezingu-esifushane futhi overloads ngesikhathi yokwanda kwama. Labelling amadlambi isetshenziswa umzimba, iqukethe izici zabo eziyinhloko. On kubo ungathola umbono ophelele zedivayisi.

Circuit Breakers: kophawu futhi wokugubha

Kukhona izinhlobo eziningi imishini, isibonelo, uhlobo oludala - AE20HHH.

Ngokwesibonelo, i-umshini kophawu AE2044 ziqala ngale ndlela: 20 - Development, 4 - 63, 4 - olulodwa isigxobo ezishisayo kanye kagesi uhambo iyunithi. Idivayisi libhekene isici umbala omnyama karbolitovogo umzimba.

othomathikhi kophawu sikimu zilandele izilinganiso ezithile. Injongo yayo oyinhloko ukuletha kucace kakhulu kubasebenzisi nemingcele main zedivayisi.

Labelling amadlambi ukufunda emzimbeni kusukela phezulu kuya phansi.

1. Umenzi noma uphawu lokuhweba - Schneider, ABB, IEK, EKF.
2. Inombolo ye-serial noma lwemibhalo (S200U chungechunge, inkampani SH200 ABB).
3. Isikhathi-zamanje isici (A, B, C) futhi ampere isilinganiso (mina _nom.).
4. voltage esinesilinganiso.
5. Eliphelele elivumelekile kuphulwa Inani lamanje ngoba k. S.
6. Class umkhawulo zamanje.
7. Umkhiqizi Ingxenye, lapho ungathola lolu hlobo umshini kwisikhangisi.

Isithombe esingezansi sibonisa kanjani kokuphawula amadlambi ABB futhi Schneider.

ukuvulwa pushbutton kumakwe noma wabonisa abomvu. Uma ungomunye kuphela, futhi ngokucindezela senziwa ke sesimweni isifaca kusho ukuthi wesifunda ivaliwe.

Ukumaka wesifunda amadlambi ngesikhathi abakhiqizi okuyinhloko kuhlanganisa QR code-, lapho lonke ulwazi mayelana imodeli kubonakala. Ukuba khona kwabo kuyinto uhlobo isiqinisekiso izinga.

Ithonya imvelo

1. Ububanzi lokushisa onobuhle kodokotela ku ezahlukene kusukela -5 ° C kuya +40 ° C. Ukuze usebenze ngale le mikhawulo kukhicite imodeli ekhethekile.
2. Ivunyelwe umsebenzi apharathasi ngesikhathi umswakama nesihlobo 50% ngo-40 ° C. Lapho kuwa ovumelekile umswakama lokushisa inyuka (kufika ku-90% ngo-20 ° C).

izinhlobo imishini

Imishini akhethiwe kuncike wesifunda kagesi.

1. Single-pole othomathikhi

Amadivayisi asetshenziswe owodwa esigabeni amanethiwekhi. Isigaba ixhunywe ku-ukuphela engenhla futhi umthwalo - kuze kufike phansi. Ixhuma kudivayisi ikhiqizwa wire igebe isigaba ukuquma amandla umthwalo uma eziphuthumayo.

2. I-Bipolar Machine

Ikhipha idivayisi kuyinto block amabili odnopolyusnikov exhunywe isigwedlo. Khiya phakathi off indlela yakhelwe ukuze isigaba se-zero off ngaphambili (ngokuvumelana nemithetho ye-Sae).

3. Umshini emithathu pole

Idivayisi isetshenziswa ukuze uvale ugesi ezintathu okhombisa inethiwekhi uma kwenzeka ingozi. Enamaphuzu amathathu ihlanganisa 3 odnopolyusnika ne ukulungiswa umsebenzi kanyekanye. I ukukhishwa kagesi futhi ezishisayo wenziwa eceleni Isifunda ngasinye siqhuba.

Circuit full: Ukucaciswa

Machines angase abe ezahlukene isikhathi samanje izici:

a) kuncike wamanje;
b) esizimele wamanje;
c) esinezinyathelo;
d) ezintathu isigaba.

On the hulls imishini kakhulu ungabona bofeleba B, C, D. Labelling amadlambi B, C, D lisho isici ibonisa ukuthi ukwencika isikhathi Ukusabela K ubuhlobo umshini = I / I _NOM.

1. B - ukuvikelwa ezishisayo icushiwe ngokusebenzisa 4-5 ne okweqa izikhathi 3 kwenani eliyimali, futhi kagesi - e 0,015 imizuzwana. Amadivayisi zenzelwe mithwalo nangowodwa ongaphakeme inrush imisinga, ikakhulukazi ngenxa ukukhanyisa.
2. C - isici ezivamile imishini ukuvikela ukufaka kagesi ngokulinganisela inrush imisinga.
3. D - yemishini kanye umthwalo imisinga ezinkulu ukuqala.

Isici isikhathi samanje amanga izici yokuthi ngezinhlobo efanayo imishini amahlelo B, C no-D bayophelelwa wokusebenza at exceedances ezahlukene zamanje.

Ezinye izinhlobo imishini

1. MA - ngaphandle ukukhululwa ezishisayo. Uma iketango isethwe edluliselwe zamanje, ukuqinisekisa i-full wesifunda kuphela Ukuvikelwa isekhethi.
2. A - ukushisa ukukhululwa kucushwa uma esingeqile mina _nom. izikhathi 1.3. Kulokhu, isikhathi sokulala kungaba 1 ihora. Uma ukubaluleka kudlulwe izikhathi 2 noma ngaphezulu, ukukhululwa wamanje kwabangela ngokusebenzisa 0.05. Uma kwenzeka ukwehluleka lokhu kuvikela esebenza 20-30 nge ukuvikelwa okweqile. Umshini nge isici okokuvikela electronics. Kukhona futhi isetshenziswa idivayisi isici Z.

othomathikhi nenqubo yokukhetha

1. Mina _NOM. - the ngokweqile of okuholela nokucupha isivikelo sindisa. Ihlelo ekhethiwe ngokuvumelana ovumelekile esiphezulu wiring zamanje, bese uyinciphise 10-15%, ukukhetha kwibanga ejwayelekile.
2. ashukumisa zamanje. Class usuke we full wesifunda kuyakhethwa kuye ngohlobo lomthwalo. Ngezinhloso yasekhaya, isici esivamile iningi S.
3. Selectivity - abakhethayo ukuvala shaqa impahla. Machines akhethiwe isilinganiso zamanje, kudivayisi waqale wasebenza kahle ohlangothini umthwalo. Okokuqala, cisha Ukuvikelwa ezindaweni lapho short circuit noma inethiwekhi ogcwele kakhulu kwenzeka. Isikhathi ukubandlulula ikhethwa ukuze isikhathi Ukusabela kwakuthinta besaziphilela umshini, esemgwaqweni eduze okuphakela amandla.
4. Inombolo izingongolo. On the ezintathu okhombisa okokufaka umshini ixhunywe lemijabo ezine, futhi isigaba esisodwa - ne elilodwa noma amabili. Ezibani zasendlini ukusebenzisa ku odnopolyusnikah. Uma ikhaya ine kubhayela kagesi noma motor ezintathu okhombisa, imishini emithathu isigxobo asetshenziselwa kubo.

ezinye izinketho

Lapho aluthola isici wesifunda full kufanele bakhethwe ngokuhambisana nemibandela yokusetshenziswa nokuthi kwenethiwekhi. Umshini ngamunye yakhelwe inombolo ethile imijikelezo wokusebenza. Njengoba inkinobho umthwalo is hhayi Kunconywa ukuba ayisebenzise. Isibalo imishini ekhethwe isidingo. Qiniseka ukusetha ukuvulwa, futhi ngemva kwakhe - ku ukukhanya umugqa Izitolo futhi ngokwehlukene abathengi enamandla. Izindlela lokukhuphula onobuhle ezahlukene zingahluka. Ngakho-ke ezikhethiwe idivayisi efanayo efakwe Ekhabetheni.

isiphetho

Ukumaka wesifunda amadlambi liyadingeka ukuze ukhethe kubo ngokuvumelana nezidingo zakho. Izici zihlobene ngokuqondile esigabeni Izintambo zikagesi ezisobala kanye umthwalo izinhlobo. Lapho short circuit kwenzeka ngokuyinhloko ezithothene ukukhishwa kagesi, ngesikhathi overloads nokunwetshiwe - Ukuvikelwa ezishisayo.
