Amakuru
Bigenda bite iyo urenze ku mahame agenga insinga z'ibikoresho?
Insinga z'ibikoresho zitujuje ibisabwa zitera igihombo cy'amajwi, kwangirika kw'ibikoresho, ndetse n'ingaruka z'umutekano.
Amakuru y’inganda agaragaza ko 80% by’ibikoresho bitujuje ibisabwa bihura n’ibibazo mu mezi 18.
Menya ingaruka nyazo zo gusimbuka ibisabwa na EN 50288-7, IEC 60332, cyangwa NEC - n'impamvu kubahiriza amategeko birinda uruganda rwawe.
Nigute wahitamo insinga ikwiye y'ibikoresho byinshi ku mushinga wawe?
Guhitamo insinga z'ibikoresho byinshi bisaba kumenya umubare w'ibikoresho bibiri (1-100+), ingano ya kondukita (18-24 AWG / 0.5-2.5mm²), ubwoko bw'igikingira (foil/braid/composite), n'ibikoresho bya jaketi (PVC/LSZH/PUR).
Iyi mfashanyigisho ikubiyemo iyubahirizwa rya EN 50288-7 hamwe n'uburyo bwo guhitamo intambwe ku yindi bw'ibimenyetso bya analogi na digitale.
Ibisobanuro Bisanzwe bya EN 50288-7: Icyo abaguzi b'insinga z'ibikoresho bagomba kumenya
EN 50288-7 ni igipimo ngenderwaho cy’i Burayi ku bijyanye no gushyiraho insinga z’amashanyarazi no kuzigenzura, kigaragaza ibipimo by’amashanyarazi (impedance, capacitance, attenuation), imiterere ya mekanike, kugabanya umuriro, n’ibipimo by’ubushyuhe.
Abaguzi bagomba kugenzura ko ikimenyetso cya CE n'ibisobanuro by'umushinga byujuje ibisabwa.
Menya ibisabwa by'ingenzi n'urutonde rw'ibyo ugomba gukora kugira ngo uhitemo.
Twisted Pair vs Coaxial vs BS5308: Ni iyihe nsinga y'ibikoresho ukwiye guhitamo?
Guhitamo hagati y’uburyo bwo gusimbuka (crosstalk reduction), coaxial (high-frequency), na BS5308 (peteroli na gaze spec) biterwa n’ubwoko bw’ikimenyetso cyawe, intera, n’ibidukikije.
Impande zombi zizunguruka neza kuri 4-20mA na RS485. Ifite uburebure bwa coaxial kugira ngo ikoreshwe mu buryo bwa frequency yo hejuru kandi ikoreshe videwo.
BS5308 yongereraho uburinzi bwa mekanike n'igipimo cya IS ku nganda zikora peteroli.
Insinga y'ibikoresho birinda uburinzi ni iki kandi kuki kurinda uburinzi ari ingenzi?
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.
Ingufu zo kugabanya imigabane iri munsi ya 70% ku isoko mu nsinga z’umutekano zo mu birombe by’amakara byo muri Ositaraliya | Dingzun Cable
Shanghai Dingzun Cable yagiranye ubufatanye bw'imyaka 5 n'itsinda ry'abacukuzi b'amabuye y'agaciro batatu bo muri Ositaraliya, itanga 70% by'ibikoresho byabo by'ikoranabuhanga bidafite umutekano (IS). Menya uburyo insinga zacu zemewe na Ex-ia, zifite ubushobozi buke, zikemura ibibazo bikomeye by'ibidukikije.
Ese volti 24 zitekanye imbere mu mubiri?
Igisubizo cy'ido n'ido ni: Oya.
Ese insinga zitekanye zigomba kuba ubururu?
Yego, nk'uko IEC 60079-14 ibivuga, insinga zitekanye zigomba kuba zifite agakoresho k'ubururu bwerurutse (RAL 5015) kugira ngo zimenye ahantu hashobora guteza akaga.
Iyi kode y'amabara itegetswe yemerera guhita ubona imiyoboro ya IS, ikarinda guhuza imbaraga zitari iza IS mu buryo butunguranye.
Hari ibintu bike bidasanzwe ku nsinga nto cyane n'ibikoresho bisanzwe bihari.
Insinga ya SWA Armoured itekanye cyane ni iki?
Insinga ya SWA (Steel Wire Armour) ifite umutekano mu buryo bugaragara ihuza ingufu nke (IS) n'uburinzi bwa mekanike (icyuma cy'insinga). Ubudahangarwa bwo gukubita kugeza kuri 4.000 N/10cm, uburinzi bw'imbeba/udukoko, n'imbaraga nyinshi zo gukurura mu gushyira ahantu hashobora guteza akaga. Agakoresho k'ubururu bworoheje ka LSZH gakomeza kubahiriza IS mu gihe intwaro yongereye igihe kirekire.
Insinga y'umuriro irinda inkongi ni iki?
Insinga yo kubuza umuriro mu buryo bwizewe ihuza ingufu nke (irinda umuriro) n'ubuziranenge bw'uruziga (ikomeza gukora mu gihe cy'inkongi y'umuriro).
Yemejwe ko ikoreshwa mu bice biteje akaga (Agace ka 0/1/2) ifite amanota nka FE180 (iminota 180 yo kurokoka inkongi y'umuriro) na LSZH sheathing.
Menya uburyo insinga z'umuriro za IS zibona inkongi z'umuriro zitaziteye.
