Kodi pali kusiyana kotani pakati pa chotchinga chotchinga ndi chotchinga chotumizira mauthenga?
Kusiyana kwakukulu ndikuti chipika cha chotchingira chimaphatikizapo makoma okwezeka pakati pa malo aliwonse otchingira ndi maulumikizidwe oyandikana nawo, pomwe chipika cha chotchingira nthawi zambiri chimakhala ndi mabowo otseguka kapena otsekedwa popanda zotchingira zolekanitsa. Ma block otchingira amapereka chitetezo chapamwamba ku ma arc ndi ma short circuits, zomwe zimapangitsa kuti zikhale chisankho chabwino kwambiri pakugawa mphamvu yamagetsi okwera kuposa 250 V. Ma block otchingira ndi ang'onoang'ono komanso otsika mtengo pama waya amagetsi otsika komanso ma control circuits. Pochita mapangidwe a panel, nthawi zambiri timagwiritsa ntchito ma block otchingira ma AC mains ndi ma motor circuits pomwe timagwiritsa ntchito ma feed-through blocks a PLC ndi ma sensor connections.
Kodi ndi kukula kotani kwa kondakitala komwe ma block a terminal blocks angagwirizane?
Ma block a chotchingira ma terminal amakhala ndi makulidwe osiyanasiyana a kondakitala kutengera mndandanda. Ma ranges odziwika bwino amayambira pa 0.2 mm² (AWG 24) pa mawaya owongolera mpaka 300 mm² (600 kcmil) pa kugawa mphamvu zolemera. Ma block a chotchingira ma power distribution odziwika kwambiri amagwira 2.5 mm² mpaka 16 mm² (AWG 14 mpaka AWG 6). Mtundu uliwonse wa chotchingira ma terminal umatchula gawo locheperako komanso lalikulu la kondakitala pamodzi ndi torque yolimbikitsira yolimbikitsidwa ya ma terminal a screw. Kupitirira malire a waya omwe adavoteredwa kumawononga kukana kwa kulumikizana ndi kudalirika kwa nthawi yayitali.
Kodi ndingatsimikizire bwanji mtundu wa wopanga chotchingira ma terminal block?
Kuti mutsimikizire mtundu wa wopanga chotchingira chotchingira, funsani malipoti oyesera a chipani chachitatu kuti muwone mphamvu ya dielectric (nthawi zambiri 2500 V AC kwa mphindi imodzi pa UL 1059), kukwera kwa kutentha pamagetsi oyesedwa, ndi kupirira kwa makina (chiwerengero cha kuzungulira kolowera/kutulutsa). Funsani ziphaso za zinthuzo — UL 94 V-0 yoyesedwa PA66 kapena PBT imasonyeza kuchedwa kwa moto kwabwino. Pitani ku fakitale kapena pemphani kuti muwone kanema kuti muwone kulondola kwa kapangidwe kake ndi mtundu wa kusonkhana. Yang'anani zitsanzo za makulidwe ofanana a khoma lotchingira, malo otchingira opanda burr, komanso kulumikizidwa kosalekeza kwa ulusi wa screw. Wopanga wodalirika ayenera kupereka zonsezi mosazengereza.
Mukufuna wopanga zipilala zotchingira zomwe mungamudalire?
Lumikizanani ndi Yvonne ku J-GUANG kuti mupeze ma datasheet aukadaulo, zitsanzo zaulere, ndi mtengo wa polojekiti yanu yotsatira yogawa magetsi.
