Automatic differential ano haizoshandisi (RCBOs) unhu, uye mudziyo rokuti

Electricity munyika ano ane irreplaceable tsime simba. Rinoshandiswa pamba ose. Kushandisa simba rakanga njodzi, anokosha mano anoshandiswa. kuvaka kwavo uye kushanda dzingasiyana.

Dunhu namapoporodzi differential ano yakagadzirirwa maindasitiri mudzimba simba grids. Vane chaiwo mabasa. Nokuda akadaro hurongwa, simba wedzerai oparesheni anova nyore uye akachengeteka.

General unhu

The otomatiki differential ano wedunhu mudariki (RCBOs) chiri electromechanical mudziyo. Rakagadzirirwa kudzivirira munhu zvemagetsi wedunhu kubva leakage ano, uye pamusoro wayo zadzisa. naivowo runosanganisirawo kusashandisa mukana dunhu pfupi.

Emergency redunhu namapoporodzi anosanganisa kunaka redunhu mudariki uye RCD. Kana munhu auya neVadzidzi wiring, RCBOs vanodzinga iye wemagetsi kuvhunduka. Nyaya iyi zvakafanana RCD. Kana zadzisa rwakavapo pomumbure, mudziyo, uyewo wedunhu mudariki akarega unokupai magetsi kuti dunhu.

Zvisinei, Emergency redunhu namapoporodzi, ane nhamba kusiyana kubva zvakafanana nayo aggregates. Magadzirirwo chinoreva duku pasuru mano mbiri dziri pamusoro apa. Constituent zvinhu hwaimiririrwa siyana haizoshandisi kuvabvumira kuti kushandiswa zvakawanda nzvimbo nemabasa evanhu.

patani

Kusiyana otomatiki differential kuitika redunhu namapoporodzi uye RCD kunozivikanwa kunyanya kugadzirwa yavo. Ivepo chikwata ine zvikamu zviviri. Vane wokudzivirira uye masimba mabasa. The yokupedzisira unoshanda maererano nheyo imwe RCD. The kushanda chikamu, hunokonzera kudzorwa voltage chinhu kwakajairika chinja. Rinogona kuva mumwe, vaviri kana mana.

Kana nekubata chikwata anoona magetsi leakage, izvozvo kunokonzera chitaviridzo mashandiro. Izvi kudzivirira mutengi, maindasitiri michina, uyewo munhu kubva yemagetsi kuvhunduka. Special module disables dzose kushanda, uye ipapo kudzorwa mudziyo.

Emergency redunhu namapoporodzi Kusiyana RCD anonyanya hunomirirwa nekugona mudziyo kudzivirira kwete chete munhu asiwo midziyo kubva mains overvoltage.

musimboti oparesheni

Features otomatiki differential ano redunhu-namapoporodzi anobvumira kushandisa kwavo-siyana network. Akapa mano kukwanisa kuongorora uye kuziva kuitika mudunhu, vakavaka diki transformer. chaikosha ichi kunouya panyaya apo mazano uye goho voltage ane zvakasiyana ukoshi. At yakaenzana prices pamusoro ushamwari uye kuuya conductors chikwata chiri chaiye kutoshanda.

The transformer ane core. Inside anoumba munhu kuitika nekubudisa kutungamirirwa. Zvichienderana gwara yavanofanira kufamba vagara vandifungira voltage pamusoro yechipiri ichitenderera. Kana paine vhinza dzemagetsi, coils ichi ichava chokukomborerwa kuitika, zvisina razero. Panyaya iyi, kuti rinobva chinja iri kusashanda.

Automatic anoramba rinofananidza kuuya uye ichibviswa voltage. Kana simba remagineti nepakati vamwe chikonzero achishungurudzika, izvozvo unogadzirira vakachengeteka hove. Electricity dzikaita kure.

mhando

Pane akasiyana classifications RCBOs. Vanogona kuva chimwe chinhanho uye zvitatu-danho. Zvichienderana mhando wiring zvinokosha kusarudza zvakakodzera chikwata.

Kusiyanisa michina nemhaka yavo kunonyanyisa bvumidzwa uno. Pane RCBOs 32, 25, 100, 40a. Nhamba iyi inojekesa panguva ipi voltage Network otomatiki akavhara magetsi aibuda kune redunhu. The aizviti kukosha kuitika anomiririrei tsamba "C". Mumhuri network anowanzodanwa kushandiswa zviumbu C16 kana C25 (akanyorwa ezvinhu wiring).

Mune zvimwe zviitiko, kana vamwe vatengi vanotanga voltage inogona yakawedzera kakawanda. The chikwata inofanira kuva vanokwanisa munhu waruka akadaro. Kune mhando nhatu mano, izvo zvakasiyana siyana madhigirii kurwisa kune chikungiso dzenzvimbo. Category B zvinosanganisira RCBOs akagadzirirwa zadzisa panguva 3-5 kutanga. Type C mano zvakagadzirirwa kutanga mitoro zvinopfuura rwekuita ndiyo 5-10 nguva. Category D zvidzidzo angakudzivisai simba vanopinda panotanga 10-20.

Sangano uye leakage iyezvino unhu RCD

One-, four- kana maviri-danda redunhu namapoporodzi vari residual ano wedunhu mudariki akavaka unhu hwakasiyana uye RCD. leakage razvino, izvo zvaanoita midziyo, akasarudzwa "Delta" chiratidzo. Kumira pedyo nhamba inoratidza kukosha chinoratidza ichi. The zviumbu nechiyero vari milliamps (Ma).

In chiedza, musha network zviri kunyanya kushandiswa michina ine chezita leakage 10 kusvika 30 Ma. Nokuti boka samambure mano zvinodiwa nezvinhu zvinenge pamwero zvinenge 30mA. Yokusuma RCBOs anogona denominated RCD 100 kusvika 300 Ma.

Integrated unodzivirira midziyo inogona makirasi siyana. Kana chikwata zvinoreva RCD AC mhando, izvozvo anopindura chete rakatumbuka ano mhando. Kirasi A mano zvakagadzirirwa DC kudzora Namano zvemagetsi converters. Type A iri zvinowanzoshandiswa kumba network.

Kudzivirirwa kwazvakarerekera kondakita

Automatic residual ano redunhu mudariki 25a, 10a, 16a, uye dzimwe mhando vane unhu hwakasiyana kushanda RCD. Zvinoda simba. Zvinonzi akapa pamwe mazano dzaishandiswa yacho differential kudzivirirwa. Nemamwe mashoko, kuti kurukura leakage dziviriro ano, zvinoda voltage. Hurongwa anofanira kuva danho uye razero waya.

Kana disconnection rikaitika "chokutambudzika", iro buri panobviswa kwaita. Asi kana kuvhiringidza kwazvakarerekera kondakita, imwe RCD arege kushanda nokuda kwokushayiwa uwandu hwezvinhu zvose zvabatanidzwa. zvitengeswa. Kubvisa mukana panowanikwa ezvinhu akadaro, vamwe Emergency redunhu namapoporodzi muhupenyu kuvaka yavo chaiyo kudzivirira chikwata kuputsa kwazvakarerekera waya. Izvi voltage ataure.

Kana hurukuro Unit aripo, Zvinokurudzirwa zvakasimba yokugadza nayo yoga. Pakusarudza midziyo anofanira zvakaongororwa voltage relays, vachibvumira rukungiso RCD kunyange kana mumwe kwazvakarerekera kondakita.

kusarudza Features

Kuti pave nechokwadi chokuti dzose kushanda nesimba rezvokudya, zvinokosha kusarudza Emergency redunhu namapoporodzi, izvo zvichava inoenderana zvizere aripo anodawo ezvinhu. Chokutanga, ngaaverenge nhamba inodiwa ampere mudziyo.

Zvakakosha kunyora pasi zvose nesimba samambure vanoshandisa. Ivo akapeta, uye mugumisiro inokamukana nokuda voltage chinoratidza. Somuenzaniso, kana mutsara kunofambidzana mano, izvo uparadze dzinokwana 7 KW, dzemaitirwe ari sezvinotevera: 7000 W: 220 V = 31.8 A.

Next, unofanira kunhonga pedyo vakawana kukosha muchina. Mune mifananidzo muenzaniso, zvichava RCBOs 32 A. chakarurama amperes chikwata anofanira pfuura zvishoma dzemaitirwe mugumisiro yapihwa. Izvi kuitira kudzivirira zvizere.

mazita Performance

Automatic residual ano vematunhu namapoporodzi waisiyana RCD Kunyora zvinhu. It rinoshandisirwa muviri. Kana kutenga mudziyo vanofanira kufunga notation hwacho nokuda akaigadzira michina. On the muchina anoratidza hazvo kuitika, voltage, uye kunonyanyisa ano chakarurama redunhu kudzima nemambure. Uyewo, zvose zvinoitwa mudziyo zvinoratidzwa mu pasipoti yake uye chitupa yepamusoro.

The Chishandiso rinoratidza mhando yayo (zvokusarudza kana dzisiri zvokusarudza), nhamba maitikiro, uye kukura mudziyo (zvinokosha kuona mhando kugadzwa). Kunyora dzimwe uye mudzimba midziyo zvingave zvakasiyana.

The Chishandiso inoratidza tembiricha siyana umo midziyo unoshanda, mhando RCD. Inenge ose kutengeswa mano zvakagadzirirwa kushanda munyika yakaoma, kupopotedzana kamuri.

Uyewo, mudziyo vangava "Test" bhatani. Kana chakatsindirwa, tarisa kushanda ari muchina. Sikai kubata Magetsi vhinza. Muchiitiko chino, pane kuti vaongorore rakavimbika gadziriro iri yakaiswa nemazvo.

kubatanidza

Automatic residual redunhu ano namapoporodzi dzinofanirwa zvakakodzera chokuita pemambure. By kusarudza zvakakodzera anodawo ezvinhu ari mudziyo, unofanira ukanyatsoongorora mirayiridzo mugadziri wacho. Kubatanidza kuna pomumbure, izvo zvinofanirwa kuti adzivirire muchina. Zvikasadaro, zvichaita kushanda zvisiri.

Kubhururuka mano yanhasi dzakakurumbira pezvitsiga neve chete urongwa. Installation iri kuitwa kumusoro wiring mutsetse. Kakawanda, izvi zvinoda kuti Gomo racho chikwata musi ruzha-njanji.
