I-Differential vs Non-Differential Overload Relays: Umehluko Oyinhloko kanye Nezinhlelo Zokusebenza

Ukuvikelwa kokudluliselwa kokulayishwa okushisayo okuhlukile kuqhathaniswa nokungahlukanisi kwehlela ekutheni zibona kanjani izinkinga zemoto. Amasistimu okudlulisa okulayishwayo okushisayo ahlukene aqhathanisa okwamanje phakathi kwezigaba, kuyilapho amayunithi adluliswayo angenamehluko aqapha ukwakheka kokushisa esigabeni ngasinye ngokuhlukene.

Iyini i-Differential Thermal Overload Relay?

Umehluko i-thermal overload edluliselwe iqapha zonke izigaba zezimoto ngesikhathi esisodwa futhi iqhathanise amazinga azo amanje. Uma ithola ukungalingani phakathi kwezigaba, iyahamba ngokushesha. Lokhu kwenzeka ngenxa yokuthi isigaba esisodwa sidonsa kakhulu okwamanje kunezinye, sibonisa izinkinga zemoto yangaphakathi noma ukwehluleka kwesigaba.

Iyini i-Non Differential Thermal Overload Relay?

I-thermal overload relay engahlukanisi isebenzisa imichilo ye-bimetallic ngayinye esigabeni ngasinye. Uma i-current igeleza kulawa mapheshana, ayashisa. Uma i-current ihlala iphakeme kakhulu isikhathi eside, amapheshana ayagoba futhi akhiphe injini.

Umehluko vs Ukuqhathanisa Okungahlukani

Ukuzwa Umehluko Wezobuchwepheshe

Ukudluliselwa okuhlukile kusebenzisa ama-transformer amanje ukukala nokuqhathanisa imisinga yesigaba ngokuqhubekayo. Noma yikuphi ukungalingani kudala isenzo esisheshayo. Ukudlulisa okungewona umehluko kuncike ezintweni ezishisayo ezidinga isikhathi sokushisa ngaphambi kokuphendula.

Izinguquko Zesikhathi Sokuphendula

Ukuvikela okuhlukile kusebenza phakathi kwama-millisecond lapho kuthola ukungalingani kwesigaba. Ukuvikela okushisayo kuthatha amasekhondi ambalwa noma amaminithi, kuye ngobunzima bokulayisha ngokweqile, njengoba imicu ye-bimetallic idinga isikhathi sokushisa nokugoba.

Ukufaka Inkimbinkimbi

Amasistimu ahlukene adinga ama-transformer amaningi amanje, izintambo eziyinkimbinkimbi, nokulinganisa okunembile. Amayunithi angahlukani afakwa kalula ngoxhumo olulula nezilungiselelo zamanje eziyisisekelo.

Izinhlelo zokusebenza ezihamba phambili zohlobo ngalunye

Ukudluliselwa okuhlukile kufanelana nezinjini ezinkulu, iziguquli zamandla, nemishini ebalulekile lapho ukuphendula okusheshayo kuvimbela umonakalo obizayo. Ukuvikela okushisayo okungahlukanisi kusebenza kahle amaphampu, amafeni, ama-conveyors, kanye nezinjini ezijwayelekile zezimboni.

Inani lemoto yakho kanye nokubucayi kunquma ukukhetha okulungile. Imishini ebizayo ithethelela izindleko nobunkimbinkimbi.

Imihlahlandlela yokukhetha

Izindleko zokushintshwa kwezimoto ziqondisa ukukhetha kwakho. Izimoto ezingaphansi kuka-$5,000 ngokuvamile zisebenzisa ukuvikela okushisayo. Amamotho abizayo noma izinqubo ezibalulekile zidinga impendulo esheshayo yokuvikela okuhlukile.

Ikhwalithi yamandla endaweni yakho nayo ibalulekile. I-voltage engazinzile noma izinkinga zikagesi ezivamile zivuna ukuzwela kokuvikela okuhlukile ekungalinganini kwesigaba.

imibuzo ejwayelekile ukubuzwa

Iyini i-relay ehlukile ye-thermal overload?

I-thermal overload ehlukile edluliselwe iqhathanisa ukugeleza kwamanje phakathi kwezigaba zemoto kanye nohambo ngokushesha lapho ithola ukungalingani okubonisa. ukwehluleka kwesigaba noma amaphutha angaphakathi.

Yibuphi ububi bokudluliswa okuhlukile?

Ukudluliselwa okuhlukile kubiza kakhulu kunamayunithi ashisayo, kudinga ukufakwa okuyinkimbinkimbi ngezinzwa eziningi, futhi kudinga ochwepheshe abanekhono ukuze kulinganiswe kahle futhi kulungiswe.

Izixazululo Zokuvikeleka Kwezimoto Zochwepheshe

I-Simply Thenga inikeza kokubili okuhlukile nokugcwele okushisayo okudluliswayo okuvela ku-ABB, Schneider, Siemens, ne-Eaton. Ithimba lethu lihlaziya ukucaciswa kwemoto yakho kanye nezimo zokusebenza ukuze batusa izinga elilungile lokuvikela.

Sinikeza ephelele motor control solutions ukuhlanganisa abathintwayo, ama-relay agcwele ngokweqile, namasistimu okuvikela. Ukuqonda kahle izinqubo zokusetha kabusha i-overload relay isiza ukuqinisekisa ukusebenza okuphephile ngemva kwemicimbi yohambo.

Ukutholakala kwemikhiqizo yethu ehlukahlukene ixazulula izinselele zokuthenga lapho amaphrojekthi edinga izingxenye ezivela kubakhiqizi abahlukene.
