Amakuru y'Ibicuruzwa

Mu nganda ziteje akaga aho gaze, umwuka n'ivumbi rishobora gutwika bitera ibyago byo guturika buri gihe, insinga zitekanye (IS) zigaragaza uburyo bw'ingenzi bwo kugenzura umutekano w'ibikoresho bikoresha ingufu nke, itumanaho n'insinga zigenzura. Bitandukanye n'insinga zisanzwe zikoreshwa muri rusange, insinga zitekanye zigenewe kugabanya irekurwa ry'ingufu z'amashanyarazi haba mu mikorere isanzwe ndetse no mu gihe cy'ikosa, bigakuraho amasoko ashobora gutwika.

Insinga zitekanye zigomba kuba zifite ubururu bworoheje (RAL 5015) nk'uko IEC 60079-14 ibivuga kugira ngo hamenyekane ahantu hashobora guteza akaga.
Iyi kode y'amabara itegetswe yemerera abahanga mu by'amashanyarazi gutandukanya ako kanya imiyoboro ya IS n'insinga z'amashanyarazi zitari iza IS, birinda guhuza ingufu ziteje akaga mu buryo butunguranye.
Menya ibisabwa n'ibidasanzwe.

Insinga ifite umutekano mu buryo bwimbitse (IS) yagenewe gutwara ingufu nke z'amashanyarazi zidashobora gutera umuriro mu kirere giturika.

Bitandukanye n'insinga zidashobora guturika zirimo guturika, insinga za IS zirinda ibishashi burundu. Menya ibisobanuro by'insinga za IS, ibisabwa mu bwubatsi, kode y'ibara ry'ubururu, n'ibipimo by'umubiri nk'uko biteganywa na IEC 60079-11.

Insinga itekanye mu buryo bwihariye ntishobora gukora cyangwa kubika ingufu z'amashanyarazi zihagije kugira ngo zitere umuriro mu kirere giturika. Menya ibisobanuro, uburyo inzitizi zigabanya ingufu bikora, impamvu ubushobozi buke (C) n'ubushobozi buke bwo gusohora (L) ari ingenzi, n'impamvu kode y'ubururu ikenewe ku isi hose mu gushyiraho ahantu hashobora guteza akaga.

Insinga y'igikoresho gitekanye (IS) igabanya ingufu z'amashanyarazi kugira ngo hirindwe guturika ahantu hateje akaga. Bitandukanye n'imiterere idaturika (Ex-d) irimo guturika, insinga za IS zihagarika umuriro binyuze mu kugenzura voltage/amashanyarazi. Menya ibijyanye n'ibice by'ubururu, ibisabwa mu kurinda, n'ibipimo by'ibikoresho nk'uko biteganywa na IEC 60079-11.

Insinga zirinda kwangirika mu buryo bw’imbere (IS) zigabanya ingufu z’amashanyarazi kugira ngo hirindwe gushya mu kirere cy’ubucukuzi bw’amabuye y’agaciro buturika. Zifite ibipimo bya capacitance/inductance bigenzurwa hamwe n’amabara y’ubururu bw’urumuri hakurikijwe IEC 60079-11, uburyo bwo kurinda bwakozwe mu buryo bwa Ex-ia/Ex-ib, hamwe n’imiterere y’insinga zoroshye zo gupima kugira ngo zihuze n’umutekano w’ubucukuzi bw’amabuye y’agaciro munsi y’ubutaka.

Insinga zigororotse (ribbon/FFC) ni ibyuma bizigama umwanya, bifite ibyuma byinshi bifasha mu gukora robots no gukora automatike. Zifite ubwishingizi bwa FEP (-90°C kugeza +200°C), amahitamo ya mashini (CU/TC/SPC/NPC), hamwe n'uburinzi bupimwe cyangwa butapimwe. Iyi mfashanyigisho ikubiyemo uburyo bwo kohereza amakuru ku buryo bwihuse, inyungu zo gushushanya neza, hamwe n'ibipimo ngenderwaho byo guhitamo porogaramu zisaba akazi kenshi.

Oya, RS485 na CAT6 ntabwo ari bimwe. Insinga za RS485 zagenewe itumanaho rya kure mu nganda (1,200m) hamwe na impedance ya 120Ω kuri network za Modbus RTU. Insinga za CAT6 zagenewe Ethernet yihuta cyane (100m, impedance ya 100Ω) mu biro/LAN. Iyi mfashanyigisho igereranya ibipimo 12 by'ingenzi kugira ngo ifashe injeniyeri kugena neza.

Insinga za RS485 na Ethernet zifite intego zitandukanye cyane mu itumanaho ry’inganda. Iyi nyandiko igereranya imiterere yazo, ibisabwa mu kurinda, n’uburyo bwiza bwo kuzikoresha kugira ngo bigufashe guhitamo neza.

Menya impamvu Insinga za RS485 ni bo bayoboye isoko mu bijyanye no gukoresha ikoranabuhanga mu nganda. Menya ibijyanye no kutagira ingufu (120Ω), ibikoresho byo kurinda, n'uburyo bwo guhitamo igipimo gikwiye cya sisitemu za Modbus na CANopen.
