Alakaʻi Koho Poloka Terminal DIN Rail: Nā Loiloi o kēia manawa, nā Mea Hana, a me nā Kūlana Kau ʻana

TL;DR

ʻO ke koho ʻana i ka poloka terminal DIN rail kūpono no kahi panela mana ʻoihana e pono ai ke hoʻohālikelike ʻana i ʻekolu mau palena: pono ke ana o kēia manawa e ʻoi aku ma mua o ka ukana kaapuni kiʻekiʻe loa ma ka liʻiliʻi he 20%, pono ka mea hale e kū i ke kaiapuni hana, a pono ke ʻano kau ʻana e kūlike me nā kūlana EN 60715. Ke hele nei kēia alakaʻi ma kēlā me kēia kikoʻī me ka ʻikepili hiki ke helu ʻia a me nā memo noi o ke ao maoli.

I loko o nā makahiki he ʻumi o ka hana ʻana i nā poloka terminal no nā OEM ma ʻAmelika ʻĀkau, ʻEulopa, a me ʻAsia Hikina Hema, ua ʻike mākou i nā hewa koho like i hana hou ʻia - nā poloka nui no nā hōʻailona haʻahaʻa, nā alahao liʻiliʻi no nā poloka multi-level kaumaha, a me nā mea like ʻole e alakaʻi ai i nā hemahema kahua. Aia kēia alakaʻi e hoʻopau i kēlā mau hewa.

He aha nā loiloi o kēia manawa no nā poloka terminal DIN Rail?

Loaʻa nā helu o ke au o nā poloka terminal DIN rail mai 24A no nā poloka feed-through maʻamau 2.5mm2 a hiki i 232A no nā poloka mana hana kaumaha 95mm2, e like me ka mea i kuhikuhi ʻia e nā kūlana IEC 60947-7-1 a me UL 1059.

ʻElua mau helu o ke au o kēlā me kēia poloka terminal: ke au hana i helu ʻia (Ie) e like me IEC 60947-7-1 a me ke au i helu ʻia e UL. He like pinepine lākou - akā ʻaʻole mau. ʻO ke au maoli e hiki i kahi poloka ke lawe ma muli o ka ʻāpana keʻa o ke alakaʻi, ka mahana ambient, a inā ua hoʻokomo ʻia ka poloka i loko o kahi hoʻonohonoho hoʻokahi papa a i ʻole ka hoʻonohonoho i hoʻopaʻa ʻia.

Nā Loiloi Manawa Maʻamau ma ka ʻĀpana Keʻa Uea

Nā kumu hoʻemi hiki ʻole iā ʻoe ke hoʻowahāwahā

Pono e wehe ʻia ka urea o kēlā me kēia poloka terminal i ka wā e hoʻokomo ʻia ai i kahi hoʻonohonoho density kiʻekiʻe a i ʻole ma nā mahana ambient ma luna o 40C. Ma muli o nā lula laulā IEC 60947-1, e hoʻonui i ke au i helu ʻia e:

• Mahana ambient ma 60C: emi iho i 80% o ke au i helu ʻia
• Mahana ambient ma 80C: emi iho i ka 65% o ke au i helu ʻia
• Nā poloka pae he nui i hoʻonohonoho ʻia (3+ pae): emi iho i 85% no kēlā me kēia pae
• Panel i hoʻopuni ʻia me ka ea ea i kaupalena ʻia: emi iho i ka palena iki o 80%

ʻO wai ka mea hale āu e koho ai?

ʻO PA66 (Nylon 66) me ka helu lapalapa V-0 ke koho maʻamau no nā hale poloka terminal DIN rail, e hana ana mai -40C a i +120C, ʻoiai ʻoi aku ka makemake ʻia o ka polycarbonate (PC) no nā noi moakaka e koi ana i ke kū'ē ʻana o ke alualu ʻana kiʻekiʻe.

He aha nā kūlana kau ʻana o DIN Rail?

Hoʻopaʻa ʻia nā poloka terminal DIN rail ma nā ʻaoʻao TS35 (35mm ka laulā, 7.5mm a i ʻole 15mm ka hohonu) a i ʻole TS32 (32mm ka laulā) e like me ka mea i wehewehe ʻia e EN 60715 a me DIN EN 50022, ʻo TS35 ke kūlana ʻoihana no ka ʻoi aku o 90% o nā panela hoʻomalu ʻoihana.

Pehea e kau ai nā poloka terminal DIN Rail

Hoʻohana ka hapa nui o nā poloka hopena DIN rail hou i kahi ʻano laka snap-on me ka ʻole o ka mea hana: hoʻopili mua ka poloka i ka lehelehe luna o ke alahao, a laila e wili i lalo a hiki i ka wā e paʻa ai ka wāwae i hoʻouka ʻia i ka pūnāwai ma ka lehelehe lalo.

1. Hoʻohālikelike ka poloka kikowaena ma kahi kihi 15-20 kekelē, e hoʻopaʻa ana i ka clip o luna ma ka lihi o luna o ke alahao TS35.
2. Hoʻohuli i lalo ka poloka a hiki i ka wā e hoʻopā ai ka wāwae puna lalo i ka lihi o ke alahao lalo.
3. E kaomi pono — pono ʻoe e lohe i kahi kaomi leo i ka wā e paʻa ai ka pūnāwai hoʻopaʻa i kona wahi ma hope o ke alahao.
4. E hōʻoia hoʻoikaika ʻana ma ka hoʻāʻo ʻana e hāpai i ka poloka i luna me ka ʻole o ke kaomi ʻana i ka ʻaoʻao hoʻokuʻu.

Palapala Hōʻoia UL vs CE: Nā mea a nā ʻenekinia e pono ai e hōʻoia

No nā papahana ʻAmelika ʻĀkau, he mea koi ka palapala hōʻoia UL 1059 e uhi ana i nā poloka terminal a hiki i ka 600V; no nā papahana EU, ʻo ka māka CE e like me IEC 60947-7-1 ke koi kānāwai, a koi pū kekahi mau papahana i ka palapala hōʻoia TUV a i ʻole VDE.

Pehea e hōʻoia ai i nā palapala hōʻoia ma mua o ke kauoha ʻana

1. Palapala hōʻoia UL: E hōʻoia i ka helu faila UL ma ka ʻIkepili Huahana UL.
2. Hōʻike Hoʻokō CE: Pono e kuhikuhi i ka IEC 60947-7-1. E hōʻoia ma Pūnaewele kūhelu o IEC.
3. Palapala hōʻoia TUV a i ʻole VDE: E hōʻoia ma luna ʻO TÜV Rheinland a i ʻole VDE nā waihona ʻikepili.
4. Nā hoʻolaha ʻana o RoHS a me REACH: Pono no ke komo ʻana i ka mākeke EU.

Pehea e koho ai i ke ʻano poloka terminal kūpono

ʻO nā ʻano nui ʻehiku o nā poloka terminal DIN rail - feed-through, ground, fuse, disconnect, multi-level, sensor, a me ka power distribution - lawelawe kēlā me kēia i kahi hana uea ʻokoʻa.

ʻAno Screw vs Spring-Clamp: Hoʻohālikelike ʻenehana pili

Hāʻawi nā poloka terminal ʻano wili i ka ikaika hoʻopaʻa kiʻekiʻe (3-5 Nm) no nā noi au kiʻekiʻe ma luna o 100A, ʻoiai nā poloka spring-clamp e hāʻawi i ka uea wikiwiki (ma kahi o 40% ka manawa hoʻokomo emi) a hoʻomalu i ka uea o ke keʻena hoʻomalu no nā pae 24A a 65A.

ʻAno-Screw vs Spring-Clamp vs IDC: Hoʻohālikelike ʻElima-Dimension

Ke hoʻohālikelike ʻia ma waena o ʻelima mau ana hiki ke helu ʻia, hāʻawi ka spring-clamp i ke kaulike maikaʻi loa no 90% o nā noi kaohi ʻoihana, ʻoiai ʻo ka screw-type e lanakila ana i ke au kiʻekiʻe a ʻo IDC e lanakila ana i nā ʻōnaehana pre-wired hana kiʻekiʻe.

ʻO wai kāu e koho ai?

Koho i ke ʻAno Screw i ka wā: ʻoi aku ke au o ke kaapuni ma mua o 65A, ʻoi aku ka ʻāpana keʻa o ka uea ma mua o 16mm2, kahi e haʻalulu ai ke kiʻekiʻe, a i ʻole nā ​​limahana lawelawe i hoʻomaʻamaʻa ʻia me nā mea hana torque.

Koho i ka Spring-Clamp i ka wā: Inā he 65A a i ʻole ka emi ʻana o ka noi (uhi i ka >85% o nā kaapuni ʻoihana), ʻo ka wikiwiki o ka uea ka mea nui, a i ʻole e manaʻo ʻia nā hoʻololi pinepine o ka uea.
