Mafunso Ofunsidwa Kawirikawiri

Kodi kusiyana kwakukulu pakati pa ma block a terminal a 3.5mm ndi 5.08mm ndi kotani?
Kusiyana kwakukulu ndi mtunda wa pakati ndi pakati pakati pa zolumikizirana zapafupi. Kusiyana kumeneku kumapangitsa kusiyana kwa magwiridwe antchito: zolumikizira za pitch za 3.5mm ndizochepa kwambiri ndipo zimayenera kugwiritsidwa ntchito pamlingo wa chizindikiro mpaka pafupifupi 13A ndi 200V, pomwe zolumikizira za pitch za 5.08mm zimakhala ndi waya waukulu (mpaka 4mm²), ma current rating apamwamba (15A–24A), ndi ma voltage rating apamwamba (mpaka 300V). Banja la 5.08mm limaperekanso mwayi wofikira pa screwdriver yayikulu, mtunda wokulirapo komanso womasuka kuti IEC itsatire, komanso kutentha bwino - zomwe zimapangitsa kuti ikhale chisankho chachilengedwe cholumikizira magetsi m'misika yamafakitale yolamulidwa.

N’chifukwa chiyani chotchingira chotseka chili chofunikira m’malo ogwedezeka?
Chitseko chotseka chimapereka mphamvu yosunga makina yomwe imaletsa pulagi kugwira ntchito momasuka pamene ikugwedezeka nthawi zonse kapena kutentha kumasinthasintha. Popanda kukhudzana bwino, kukana kulumikizana kumawonjezeka pamalo olumikizirana omasuka, zomwe zimapangitsa kutentha komwe kumathandizira kusungunuka kwa okosijeni ndipo pamapeto pake kumapangitsa kuti kulumikizana kulephereke. M'malo opangira magetsi okhala ndi magetsi amphamvu kapena ma circuits ofunika kwambiri, kulumikizana kosasunthika kungayambitse nthawi yosakonzekera yogwira ntchito, kusokonezeka kwa ntchito, komanso zoopsa zamoto. Chitseko chotseka si chowonjezera—ndicho chinthu chachikulu chosungira chomwe chimapangitsa kuti zolumikizira zolumikizidwa zikhale zogwira ntchito m'malo ovuta.

Ndi ziphaso ziti zomwe ndiyenera kuyang'ana kuchokera kwa wopanga ma terminal block omwe amatha kutsegulidwa?
Yang'anani CE (kutsata malamulo a ku Ulaya), UL (chitetezo cha ku North America), CSA, kapena VDE. Satifiketi yoyang'anira khalidwe la ISO 9001 imasonyeza khalidwe lokhazikika la kupanga ndi kusinthasintha kwa lot-to-lot. Pa malo ogwedezeka, pemphani malipoti oyesera motsutsana ndi IEC 60068-2-6 kapena miyezo yofanana. Satifiketi yeniyeniyo ndi yofunika: onetsetsani kuti ikukhudza banja lenileni la malonda ndi kapangidwe kake ka pitch komwe mukufuna kugwiritsa ntchito, osati kungonena mawu ambiri.

Kodi ma block a terminal a 3.5mm pitch amatha kulumikizana ndi ma motor a mafakitale?
Kawirikawiri sikoyenera kwa ma mota opitirira ma watts mazana angapo. Ma rating apano ndi zoletsa za kukula kwa waya za zolumikizira za 3.5mm pitch zimapangitsa kuti zikhale zosayenera kulumikizana ndi mphamvu ya mota. Zapangidwira zotulutsa za I/O—PLC, masensa, ndi zida. Kuyesa kuzigwiritsa ntchito polumikizana ndi mota kumabweretsa kutentha kwambiri, kulephera kugwira ntchito, komanso zoopsa zina zomwe zingachitike. Pa kulumikizana ndi mota, gwiritsani ntchito mawonekedwe a 5.08mm kapena pitch yayikulu yomwe ikugwirizana ndi zomwe magetsi ndi magetsi amafunikira pamagetsi a mota.

Kodi ndi kukula kotani kwa waya komwe kumagwirizana ndi ma terminal block a 5.08mm pitch pluggable?
Mapangidwe a waya a 5.08mm ochokera kwa opanga ambiri amavomereza kukula kwa waya kuyambira 0.5mm² mpaka 2.5mm² wolimba kapena wosweka, ndi mitundu ina yotentha kwambiri kapena yapamwamba kwambiri yomwe imayesedwa mpaka 4mm². Zofunikira pa waya wa waya ndi screwdriver torque zimasiyana malinga ndi wopanga—nthawi zonse funsani deta yeniyeni ya nambala yanu ya magawo yomwe mwasankha kuti mutsimikizire njira zokonzekera waya ndi kuimitsa waya.

Kodi ndingatsimikizire bwanji zonena za magwiridwe antchito a kugwedezeka?
Pemphani lipoti la mayeso la wopanga motsutsana ndi EN 60068-2-6 (kugwedezeka kwa sinusoidal) kapena IEC 60068-2-27 (kugwedezeka). Lipotilo liyenera kuwonetsa muyeso wa kukana kukhudzana ndi magetsi asanayambe komanso atalowa, pamodzi ndi kukula kwa kuthamanga, kuchuluka kwa ma frequency, ndi kuchuluka kwa ma cycles omwe ayesedwa. Wogulitsa wodziwika bwino wa pluggable terminal block adzapereka zikalatazi mosazengereza, ndipo delta ya kukana kukhudzana iyenera kukhala pansi pa 5 milliohms pazochitika zonse zoyesedwa. Musakayikire ogulitsa omwe amangotchula kugwedezeka popanda kutsimikizira ndi lipoti loyesa lolondola, lolembedwa ndi labotale yovomerezeka kapena malo oyesera mkati.
