Ishadi Lokukhetha Lokulayishwa Okudluliselwe Kwe-Schneider: Isinyathelo Ngesinyathelo Umhlahlandlela Wokuvikela

Ukukhetha i-Schneider overload relay efanele kubalulekile ukuze kuvikelwe izinjini, ukunciphisa isikhathi sokuphumula, nokuqinisekisa ukuthotshelwa kwezindinganiso zokuphepha. Amashadi okukhetha asemthethweni ka-Schneider enza le nqubo ibe lula, futhi ngokuwahlanganisa nokutholakala okuthembekile okuvela ku-Simply Buy, uzovikela kokubili ukunemba nokwethembeka.

Ukunemba Ukuvikelwa Kwezimoto Zakho

Ukuvikelwa kwezimoto akukaze kulingane-konke. Imoto ngayinye inezidingo zomthwalo ezihlukile, izimo zokusebenza, nezidingo zokusebenza. Kungakho ukukhetha i-relay efanele yokulayisha ngokweqile kubalulekile ekuqinisekiseni ukuphepha, ukuvimbela ukwehluleka okumba eqolo, nokwandisa impilo yemoto.

I-Schneider Electric isekela le nqubo ngezikhombo ezinemininingwane, njenge-PDF yekhathalogi ye-Schneider yokulayishwa okungaphezulu kwe-relay kanye neshadi le-PDF le-Schneider lokukhetha i-overload relay. Lawa mathuluzi asiza abathengi nonjiniyela bafanise ukudluliswa kwangempela nezidingo zabo zohlelo lokusebenza, kungakhathaliseki ukuthi bakhetha ukudluliselwa kokushisa okuhlangene noma izixazululo ezithuthukisiwe ze-elekthronikhi.

Kungani Kubaluleke Kakhulu Ukukhetha Okudluliselwe Kwelayithi Okuyiyo

I-overload relay iwumugqa wokuqala wokuzivikela phakathi kwemoto yakho nomonakalo. Ukukhetha okulungile kunezinzuzo ezimbalwa:

• Ivimbela Ukushiswa Kwezimoto: Ukugcwala ngokweqile kungenye yezimbangela eziphambili zokungasebenzi kahle kwezimoto. Uhambo olufanele lokudluliselana ngaphambi kokuthi kwenzeke umonakalo.
• Igwema Isikhathi Sokuphumula Esingenasidingo: Amalayidi anosayizi ofanele anciphisa ukukhubeka kwenkathazo okumisa ukukhiqiza ngokungenasidingo.
• Ihlangabezana namazinga okuphepha kagesi: Ukuxhumana okulungile kwe-relay nama-SCPD (imishini yokuvikela yesiyingi esifushane) kuqinisekisa ukuthobela kwe-NEC/IEC.
• Ithuthukisa Ukuphila Okude Kwezisetshenziswa: Ukuvikela okuhambisana ne-motor Full Load Amps (FLA) kwandisa impilo yesevisi yemoto.

Ukukhetha i-relay engalungile, ngakolunye uhlangothi, kungabangela ukwehluleka kwemoto ngaphambi kwesikhathi, izindleko eziphezulu zokushintshwa, noma ukumiswa okungadingekile ekukhiqizeni.

Ukuqonda Ishadi Lokukhetha I-Schneider Overload Relay

Ishadi le-Schneider eliningiliziwe lokukhetha i-overload lenza inqubo yokukhetha ibe lula. Leli shadi libala izici zezimoto, izinhlobo zokudlulisa okulayishiwe, nokuhambisana nohlelo lokusebenza ukuze lisize abasebenzisi benze ukukhetha okunembile.

Amapharamitha abaluleke kakhulu eshadini afaka:

• Ama-Amps Omthwalo Ogcwele Wezimoto (FLA): Inani elingukhiye elisetshenziswe kusayizi wokudlulisa ngendlela efanele.
• Amandla Emoto (HP/kW): Inquma ukuvikelwa kokulayisha ngokweqile okusekelwe kumthamo wokulayisha.
• I-Motor Voltage: Iqinisekisa ukuthi i-relay ifanele ukunikezwa izilinganiso kusistimu yakho.
• Ikilasi Lohambo - Ukudluliselwa kwe-Schneider kuyatholakala ku-Class 10, 20, noma 30 (isikhathi ngemizuzwana ukuya ku-600% wamanje).
• Uhlobo Lokuqala: Ukukhethwa kuyehluka ku-Direct-On-Line, Star-Delta, noma ezinye izindlela zokuqala.
• Uhlobo lokudlulisa: Izinketho zifaka i-thermal (like TeSys LRD) ngezinhlelo zokusebenza ezijwayelekile noma electronic (njenge I-TeSys Giga Protection Relays) ngokuqapha okuthuthukile.

Lezi zithenjwa, kanye ne-PDF yeshadi lokukhetha i-Schneider overload relay, zinikeza indlela ehlelekile yokukhetha umkhiqizo onembile.

Isinyathelo Ngesinyathelo Ukukhetha Inqubo

Isinyathelo 1: Thola ama-Motor Full Load Amps (FLA)

Hlola i-nameplate yemoto ye-FLA. Ukudluliselwa kuka-Schneider kunosayizi ngobubanzi be-amp, hhayi amandla ehhashi wodwa. Isibonelo: injini engu-10 HP, 400V ingaba no-~14.8A FLA.

Isinyathelo sesi-2: Thola Izimpawu Zezimoto

Qaphela isilinganiso se-HP/kW yemoto, i-voltage esebenzayo, kanye nohlobo lohlelo lokusebenza (umsebenzi oqhubekayo, ngezikhathi ezithile, i-torque eqala kakhulu, njll.). Lezi zici zinciphisa izinketho.

Isinyathelo sesi-3: Khetha Uhlobo Lokudlulisa

Okulandelayo, khetha kuma-relay amabili alandelayo:

• Ukudluliselwa okushisayo (njenge I-Schneider LRD edlulisa ukulayisha ngaphezulu) zilungele izinhlelo zokusebenza ezijwayelekile lapho ubulula nokuthembeka kubaluleke kakhulu. Izinketho ezidumile zifaka phakathi i-Schneider Electric LRD14 edlulisela ukulayisha ngokweqile, elinganiselwe ngamamotho ayi-7–10 A.
• Ukudluliselwa kwe-elekthronikhi (njenge I-TeSys Giga Protection Relays) iletha ukunemba okuphezulu, ukuzwela kokulahlekelwa kwesigaba, nokuxilongwa okukude, okuyenza ifanelekele izinhlelo zokusebenza ezibucayi.

Isinyathelo sesi-4: Bheka Ishadi

Uma usuwazi ama-amps agcwele emoto (i-FLA) neminye imininingwane yokhiye, sebenzisa ishadi lokukhetha ukulayishwa okungaphezulu kwe-Schneider ukuze ufanise i-relay efanele. Ishadi libonisa i-FLA yakho ngebanga elifanele lokudlulisela kanye nekilasi lohambo.

Ngokwesibonelo:

• Injini elinganiselwe ngo-7–10A ngokuvamile ibiza i-Schneider TeSys LRD14 bimetallic overload relay, Ikilasi 20.
• Ukuze uthole ukunemba okuphezulu noma izici ezithuthukisiwe zokuvikela, ungase ukhethe i-Schneider LR9D solid-state relay.
• Ngokuphathwa kwezimoto okuyinkimbinkimbi, iSchneider's TeSys T Motor Management System ihlinzeka ngokuqapha, ukuxhumana, nokuvikela okubikezelwayo.

Isinyathelo sesi-5: Cabangela Izici Ezengeziwe

Ukudluliselwa kwesimanje kudlula ukuvikela ukugcwala ngokweqile. Linganisa:

• Ukulahlekelwa kwesigaba nokuzwela kokungalingani kwesigaba.
• Setha kabusha amamodi (ngesandla noma ngokuzenzakalelayo).
• Oxhumana nabo abasizayo ukuze uthole inkomba yesilawuli kude.
• Izinketho zokuhlanganisa neziqalisi ezifana ne- I-TeSys GV2 Motor Starter noma amayunithi anamandla aphezulu njenge TeSys Giga Contactors.

Amaphutha Avamile Okufanele Agwenywe Ngesikhathi Sokukhetha

Ngisho nabathengi abanolwazi bangenza amaphutha lapho bekhetha ama-overload relay. Ezinye izingibe zihlanganisa:

• Ukwehlisa noma ukweqisa i-relay - kokubili kubangela ukuvikeleka okwanele noma ukukhubeka okungadingekile.
• Ukuziba isinxephezelo sezinga lokushisa elizungezile - ukudluliselwa kungadinga ukulungiswa uma kufakwe ezindaweni ezimbi kakhulu.
• Ukuhambisana koxhumana naye okubheke phezulu - okudluliselwayo kufanele kuhambisane nobubanzi bokuxhumana ukuze kuqinisekiswe ukusebenzisana okungenazihibe, okufana nokumataniswa kokudluliselwa kwe-LRD nezixhumi ze-TeSys D.
• Ukweqa Izifundo Zekilasi Lohambo: Ukudluliselwa kwe-Class 10 kungase kube uhambo oluyinkathazo emithwalweni ye-inertia ephezulu; Ikilasi lama-20 lifaneleka kakhulu.

Ukugwema lawa maphutha kuqinisekisa ukuvikelwa kwemoto okuphelele nokuthembeka kwesistimu.
