Atatu-mtengo dera baka ichidachi: mwachidule, mitundu, mbali ndi ndemanga

breakers dera tinapangidwa pakamwa maukonde magetsi pamene choposa zikugwira ntchito madera panopa ndi waufupi. Iwo kuteteza Kulumikizana ndi olumikizidwa kwa izo ndi ogula zimamuchulukira ndipo muli mizati wina ndi anayi. Atatu-mtengo dera baka ichidachi lakonzedwa kuteteza atatu gawo dera kapena nthawi yomweyo atatu gawo Kulumikizana. Ngati mmodzi mwa mizere ya ngozi, olumala yomweyo atatu mizati.

chipangizo zochimwazo kumathetsa ntchito zotsatirazi:

• chitetezo maukonde gawo;
• kusokonezeka popewa gawo dera;
• kusankha olondola a kupewa maulendo wosaloleka.

Makhalidwe zazikulu za makina - izo oveteredwa mphamvu kumatula ndi liwiro kudula kwambiri. Iwo ntchito awiri shutdown zimagwirira: matenthedwe ndi mu atomu. Woyamba akutsegula dera pamene dera lalifupi, ndipo chachiwiri - zochita za mosalekeza panopa kwakukulukulu mwadzina. Mfuti angagwiritsidwe ntchito ngati lophimba kudzera chinsinsi kulamulira.

Yoyezedwa mphamvu kumatula

Mbali mtengo limasonyeza pazipita chovomerezeka yochepa dera panopa pa zimene lophimba akhoza kusagwirizana Kulumikizana zipangizo chikugwirizana thereto kamodzi. Iwo anasonyeza pa nyumba ya makina ndipo ali ndi ubwino:

• 4,5 Ka - kuteteza ndi lalifupi mizere m'munda dera la chuma payekha, pomwe kukana mzere katundu ku substation kuti sali wamkulu kuposa 0,05 ohms;
• 6 Ka - kuteteza gawo zogona ndi malo onse kumene mzere kukana si poyerekeza 0,04 ohms;
• 10 Ka - ntchito popewa kuwonongeka kwa mizere mphamvu padziko substation lapansi.

analimbikitsa kusinthidwa 6 Ka chitsanzo madera zoweta.

makhalidwe nthawi zangochitika

Pamene m'goli mowa mphamvu chifukwa cha katundu kusintha ndi kuwapangitsa kapena disabling zipangizo dera, pangakhale positives onyenga zipangizo zodzitetezera chifukwa wozingidwa ndi oveteredwa panopa. Kuchepetsa mosavuta kudzipheralo makina ntchito ndi anakonzeratu makhalidwe nthawi zikusinthira (BTX). Chizindikiro limasonyeza cutoff nthawi chiŵerengero ena a panopa kufunika mwadzina. BTX akutsatira.

1. B - ndi mu atomu ulendo wagawo maulendo pambuyo masekondi 0,015 pa kuchuluka zitatu masiku ano pankhani ya mtengo mwadzina.
2. C - khalidwe ambiri pamene chitetezo kumayambika ndi kuwonjezera phindu mwadzina nthawi 5. Makina ali oyenera kuunikira ndi zipangizo ndi mafunde zolimbitsa inrush.
3. D - makina lakonzedwa kuti lalikulu mafunde inrush, monga pamene kukatentha magetsi, Motors magetsi ndi zina zipangizo atatu gawo. Zimagwiritsa ntchito mu makampani.

Machine chikugwirizana pakati gwero mphamvu ndi Kulumikizana, amene ayenera kutetezedwa. Atatu-mtengo dera baka ichidachi limapangidwa atatu awiriawiri kukhudzana, aliyense chikugwirizana pa mndandanda ndi matenthedwe ndi mu atomu mayunitsi ulendo. gawo Makinawa kuletsa yekha popanda kuswa ndale, amene si olumikizidwa kwa izo. Ngati mukufuna kusagwirizana waya ndale, ntchito zinayi mzati chitsanzo. Childs, iwo ntchito pa athandizira chachikulu.

The nyumba ndi m'nyumba ntchito makina a kalasi kwa katundu zolimbitsa. Mphamvu panopa amasankhidwa molingana ndi mphamvu ya zipangizo zikugwirizana kumene pakhomo kawiri chipembedzo kuthetsa positives onyenga.

Kugawira mankhwala IEK Makampani, wa EKF, DEK, INTES ndi "contactor". mankhwala zoweta ndi kudalilika okwanira ndi mitengo wololera. Ambiri amagwiritsa ntchito makina mu 16 ndi 25 A. Imports ndi okwera mtengo kwambiri, koma makampani odziwika ndi kubala mkulu khalidwe ndi zitsanzo odalirika. Pa lophimba basi mtengo atatu-mtengo ku makampani odziwika mosiyana kwambiri, koma mogwirizana khalidwe.

chipangizo zitetezeni ndi atatu gawo panopa umagwiritsidwa ntchito pa Muzifunsa nyumba ndi zida akatswiri mphamvu ndi voteji a 380 V Mwachitsanzo, yaotomatiki atatu-mtengo 100A lophimba.

Mphamvu imeneyi zogwirizana kauntala, ngati yaima pambuyo lophimba lapansi. Kawirikawiri osapitirira 63 A. A amphamvu kwambiri atatu-mtengo dera baka ichidachi ntchito mu makampani.

Ku maganizo ndi malangizo a zamagetsi odziwa ndizoonekeratu kuti makina ndi zipembedzo kukambapo Mulimonsemo sangathe ntchito. Izi chiopsezo cha moto kapena kulephera kwa chida cha.

The zinayi waya atatu gawo ndi ziro umaperekedwa kwa nyumba ntchito. Iwo kawirikawiri ntchito zida oveteredwa pa 380 V. The mbali mu gulu yogawa anasiyanitsidwa. Akamatere 3 mzere osiyana ndi voteji a 220 V.

The ntchito makina Mipikisano mzati ndi luso imodzi kulamulira mizere angapo. Mwa khazikitsa yaotomatiki atatu-mtengo lophimba 25a atatu wagawo lolingana mphamvu kulamulira angathe kuchitidwa pa chiganizo chilichonse payekha. Mu chochitika cha dera yochepa mmodzi wa iwo kutchinga zonse mwakamodzi. Childs, pa chilichonse mzere kukhazikitsa zina osakwatiwa-gawo dera breakers. Pamene wina wa iwo amalephera gawo ntchito, amene kumawonjezera dongosolo kudalirika.

BA makina mndandanda

makina zoweta zinabala mndandanda AE ndi BA. Yoyamba ndi achikale, ndipo kawirikawiri ntchito. Iwo ali wochepa mphamvu ya thupi, kusowa kugwirizana kwa Din-njanji. Ntchito zapakhomo ndi bwino yosayenera mankhwala mndandanda VA masamu kuti mafunde mpaka 63, khalidwe B, C, D, ndi luso kunyema 4.5 Ka.

M'banja atatu-mtengo dera breakers VA kwathunthu akukumana amafuna ano, pamene kusunga mtengo wotsika kwambiri kuposa zitsanzo kunja.

Malinga ndi ndemanga zambiri, zitsanzo kunja kukhala wangwiro pa mitengo ngati mkulu. Koma iwo misfire, ngakhale zitsanzo zochepa za m'banja.

Pomaliza

Atatu-mtengo dera baka ichidachi ndi mbali yofunika ya dongosolo nyumba za magetsi. Kusankha zitsanzo mtengo, tiyenera adzanyamula kukumbukira kuti ena a zipangizo ayenera kukhala mlingo yemweyo: Kulumikizana, masiwichi ndi zitsulo, mabokosi yakumapeto, kuyatsa mindandanda yamasewera.

Makhalidwe waukulu makina nthawizonse pali mbali yakutsogolo kwa nyumba ya. Iwo amasankhidwa zochokera waya kukula ndi ukulu wa katundu chikugwirizana.
