Three-danda redunhu mudariki: muchidimbu, mifananidzo, zvinhu uye wongororo

Dunhu namapoporodzi akagadzirirwa zvakamboda kukanganisa zvinhu zvemagetsi rezvebonde apo runopfuura kushanda matunhu kuitika uye pfupi. Ivo kuchengetedza wiring uye chokuita nazvo vatengi wakaremedza uye ane mumwe mana nematanda. Three-danda redunhu mudariki akagadzirirwa kudzivirira -danho matatu redunhu kana panguva iyo-danho matatu wiring. Kana mumwe mitsetse tsaona, vari ngomwa pakarepo matatu nematanda.

The mudziyo anogadziriswa zvinotevera mabasa:

• inodzivirira Network chikamu;
• Kuparara kudzivisa redunhu mugove;
• yakarurama kusarudza kudzivisa kunze komutemo yenzendo.

Feature ukoshi kunoratidza kufadza bvumidzwa pfupi-redunhu kuitika panguva iyo chinja anokwanisa patsanura kuti wiring kuti mano chokuita kwachiri kanenge kamwe. It inoratidzwa pamusoro dzimba ari mumuchina uye ane kukosha:

• 4,5 Ka - kudzivirira pfupi wedunhu munda akarongwa private pfuma, apo kurwisa mutsetse mitoro kubva substation kuti haana kupfuura 0,05 ohms;
• 6 Ka - kudzivirira chokugara nemauto uye dzevoruzhinji, uko mutsetse nemishonga haisi kudzika pane 0,04 ohms;
• 10 Ka - kushandiswa kudzivisa kuvadza simba mitsara yakapoteredza substation.

Recommended nadzurudzo 6 Ka muenzaniso mumhuri matunhu.

Time-iyezvino unhu

Kana gogonera simba kuparadzwa kunokonzerwa mutoro kushanduka uye kugonesa kana waipedza redunhu mano, pangava positives venhema wokudzivirira mano nokuda runopfuura yavose sezvavakatarirwa uno. Kuderedza mukana wokuita triggering kushandiswa michina pamwe zvakafanorongwa nguva-iyezvino maitiro (BTX). Parameter inoratidza cutoff nguva pane imwe nhamba kuitika kune aizviti ukoshi. BTX vari kutevera.

1. B - imwe remagetsi rwendo chikwata panzendo pashure 0,015 masekonzi panguva katatu kuwedzera kuitika panyaya aizviti ukoshi.
2. C - vakawanda unhu kana chokudzivirira kukonzerwa kuwedzera aizviti ukoshi 5 nguva. Michina vari dzakakodzera okuvimba uye midziyo yemagetsi ine mwero inrush dzenzvimbo.
3. D - michina rakagadzirirwa hombe inrush dzenzvimbo, zvakadai sepaya yemagetsi bhaira, dzemagetsi Motors nevamwe-danho matatu namano. Ainyanya kushandiswa indasitiri.

Overview namapoporodzi

Machine zvakabatana pakati nesimba kunobva uye wiring, izvo zvinofanira kuchengetedzwa. Three-danda redunhu mudariki unotora kuonana mbiri matatu, apo mumwe nomumwe hwakabatana mu ngaatevedzane ine chafariz uye remagetsi rwendo dzakabatana. Automatic danho chokukuvadza chete pasina yokuputsa kwazvakarerekera, iyo isina zvakabatana naro. Kana uchida kuti patsanura kusatsigira waya, vakashandisa mana-danda womuenzaniso. Kazhinji, vari kushandiswa iri huru chiyamuro.

The Apartments uye misha vaishandisa michina dzekirasi kuti mwero zvinorema. The simba razvino anosarudzwa maererano nesimba kunofambidzana mano, apo kuchikumbaridzo iri kaviri sangano kubvisa positives venhema.

Zvakaparadzira zvigadzirwa Iek yemakambani, pamusoro EKF, DEK, INTES uye "contactor". Domestic zvigadzirwa vane akavimbika zvakakwana uye zvine mitengo. Zvinowanzoshandiswa michina iri 16 A uye 25 A. Zvinhu anodhura, asi inozivikanwa makambani inobereka yepamusoro uye yakavimbika yokutevedzera. On the chinja otomatiki -danda matatu mutengo kubva anozivikanwa makambani angava akasiyana chaizvo, asi unoenderana unhu.

Sechokudzivirira pamwe-danho matatu iyezvino rinoshandisirwa pa mazano weimba uye nounyanzvi yemagetsi ine voltage pakati 380 V Somuenzaniso, imwe otomatiki-danda matatu 100A chinja.

simba iri vanofanira dzinoenderana pakaunda, kana inomira mushure chinja. Kazhinji hazvisi kupfuura 63 A. A kupfuura simba-danda matatu redunhu mudariki rinoshandiswa indasitiri.

Kubva inofambiswa uye mazano ruzivo Electricians zvinoreva kuti michina ine masangano dzakanaka chero zvazvingava haagoni kushandiswa. Uyu mukana moto kana kukundikana huchashandiswa.

Mana-waya matatu-danho uye razero riri akapa kuti kushanda mudzimba. Vari kashoma kushandiswa michina yavose sezvavakatarirwa pa 380 V. The maitikiro ari kuparadzirwa Panel vanoparadzaniswa. Izvi zvinobereka zvibereko 3 yoga mutsetse ane voltage kuti 220 V.

Kunakisa multi-vedanda michina iri kukwanisa panguva kudzora vakawanda mitsetse. By nekuisa mumwe otomatiki-danda matatu chinja 25a-chikwata matatu runoenzanirana simba kudzora zvinogona kuitwa musi mumwe nomumwe mutsetse. In zvinoitirwawo pfupi redunhu pane mumwe wavo akavhara zvose kamwechete. Kazhinji, pane mutsetse mumwe kuisa mamwe chete-danho redunhu kutinhira. Kana mumwe wavo zvinopera basa chinhanho, iro anowedzera hurongwa rakavimbika.

BA dzino michina

Domestic michina yakabereka dzakatevedzana kwavatumwa uye BA. Chokutanga mhando ndiyo zvisingachashandi, uye kashoma kushandiswa. Ane simba pasi womuviri, kushaya riine ruzha-njanji. Nokuti mudzimba mafomu vari nani akakodzera chigadzirwa dzakatevedzana VA dzaona kuti dzenzvimbo anosvika 63 A, maitiro B, C, D, uye pakumedura anokwanisa 4.5 Ka.

Domestic-danda matatu redunhu namapoporodzi VA zvakazara rinoungana zvinodiwa ano, apo mukuchengeta mutengo dzinokwanisa kudzika pane kutorwa yokutevedzera.

Maererano zvakawanda nezvaro, kupinza mhando kuva akakwana panguva kumusoro mitengo dzakadaro. Asi ivo misfire, kunyange zvishoma mudzimba yokutevedzera.

mhedziso

Three-danda redunhu mudariki chinhu chinokosha musha wacho magetsi hurongwa. Kusarudza mhando dzinodhura, kunofanira kurangarirwa kuti vamwe zvokushandisa inofanira kuva zvakafanana chechetere: wiring, haizoshandisi nezvigadziko, mabhokisi Junction, chiedza Fixtures.

The chikuru zvechadenga michina nguva dzose ipapo pamberi divi redzimba. Ivo vanosarudzwa kwakavakirwa waya Ukuru pamwero mukuru zvakabatana mutoro.
