Insait long ol wok olsem otomotiv elektroniks na indastriel kontrol, ol AVS na AVSS waia em ol i save yusim olsem ol insulet kondukta, tasol planti enjinia i save paulim ol teknikel mak bilong tupela. Dispela atikol bai brukim ol bikpela samting we i soim olsem tupela kain waia i no wankain long ol samting, pefomens na aplikesen, na helpim yu long mekim stretpela seleksen long rot bilong bungim ol 'real case'.
Difrens bilong straksa
Tupela wantaim i bilong PVC insulated waia, tasol i gat ol klia samting i narapela long disain bilong insulation leia, we em i as bilong pefomens i no wankain.
AVS waia
Ol 'conductor' em ol 'twisted soft copper wires', we ol 'wire diameters' i stat long 0.3 i go inap 2.0mm2, na dispela i bihainim JIS C 3306 standet.
AVSS waia
Insait bilong 'soft PVC' i save mekim yu inap long tanim tanim, na ausait bilong 'hard PVC' i save lukautim gut. Ol spesifikasen bilong ol kondakta i wankain olsem bilong AVS.
2.Ol aplikesen senario na ol tipikel kes
①AVS waia: Kost-ifektiv jois bilong nomol tempereja na liklik voltej senario
Ol 'automotive interior wiring harness case': Insait long 'dashboard wiring harness project' bilong wanpela liklik kar bilong wanpela 'joint venture' bren, bilong ol samting we i gat liklik voltej olsem odio sistem insait long kar (pawa 45W, wok karent 3.75A) na lait bilong ples (wanpela senel pawa 10W, 3.75A² 207A). ol i makim ol waia olsem ol koneksen waya harnes. Folem standet bilong 'copper wire -carrying capacity, 'safe current-carrying capacity' bilong 0.75mm2 kopa waia em 6-9A, na 'current current' bilong ikwipmen em i 41%-62% tasol bilong 'current-carrying capacity', we i inap long seifpela operesen redundancy. Dispela piksa i stap insait long 'cockpit', we temperaja bilong en i stap gut long -10 digri i go inap 60 digri, i no gat oil kontaminesen, na i gat bikpela wok long bosim kos. Laspela 'wiring harness' i winim 1000-aua vaibresen tes long 10-50Hz na i no gat wanpela asua. Insulesen resistans bilong insulesen leia i stap antap long 1000MΩ, na i no gat wanpela samting i kamap long taim bilong lapun. Taim yumi skelim wantaim yusim ol AVSS waia, pe bilong ol samting i go daun long 15%.
②AVSS waia: Wanpela gutpela garanti bilong ol ples we i gat bikpela hat na oil
Kes bilong ensin kompatimen bilong kar: Long 'fuel sensor connection wire harness' insait long ensin kompatimen bilong wanpela komesel kar, ol i makim 1.0mm2 AVSS waia. Dispela eria i save stap oltaim long wanpela hai-temperature envairomen bilong 80 digri i go inap 100 digri. Taim yu no wok, tempereja bilong ples inap long kamap 105 digri, na i gat sans long oil bilong ensin i ken lik (mineral oil i stap aninit long o wankain olsem 5mg/cm2). Karent-karin kapasiti bilong 1.0mm2 kopa waia insait long 105 digri envairomen em 7.2A, na wok karent bilong sensa em 4.5A, we em i 62.5% tasol bilong karent-karim kapasiti, na i inapim ol seleksen spesifikasen bilong ol hai-temperature envairomen. Bihain long wok i go het long 105 digri inap 3,000 aua, 'insulation layer thickness' bilong AVSS waia i go daun long 0.35mm i go long 0.33mm, wantaim wanpela 'attenuation rate' bilong 5.7% tasol. Tasol, 'insulation layer thickness' bilong wankain kain AVS waia i go daun long 0.1mm aninit long wankain kondisen, wantaim wanpela 'attenuation rate' bilong 28.6%. Na tu, ausait bilong en i gat strongpela PVC i bin go insait long 5,000 friksen tes (long presa bilong 5N), wantaim wear bilong 0.01mm tasol, na dispela i abrusim bagarap bilong insulesen we i kamap long friksen namel long ol waia harnes na ol komponen bilong ensin.
Negatif kes: Kost bilong rong seleksen
Long daunim kos, wanpela stua bilong stretim ol kar i senisim ol 'wiring harness' klostu long 'transmission' bilong kar (wantaim tempereja bilong 90 digri i go inap 100 digri, we i save kamapim bikpela sans long 'hydraulic oil' i ken lik) wantaim 1.0mm2 AVS waia na i no AVSS waia. Karent-karin kapasiti bilong wanpela 1.0mm2 AVS waia long 100 digri em 5.4A tasol, na wok karent bilong transmisin sensa em 4.8A, we i kamap long 88.9% bilong karent-karing kapasiti na i klostu long kritikal veliu bilong ful operesen{1}}. Bihain long ol i yusim inap 3-pela mun (inap olsem 500 aua), bikos 'insulation aging rate' i go antap long 50% long olgeta 10 digri inkris long tempereja, 'insulation layer' bilong AVS waia i soim olsem em i kamap malumalum (hatpela bilong en i go daun long 85Shore D i go long 60Shore D), em i bruk, na insulesen i go daun long taim bilong stat 1000MΩ i go aninit long 20MΩ. Dispela i mekim na 'transmission sensor signal' i bagarap, na dispela i mekim na 'gear shifting jerky fault' i kamap long kar (fault kod P0700). Bihain long senisim wantaim ol AVSS waia we i stret long lo, asua i pinis olgeta. Kost bilong senisim ol hap bilong en, 8,000 yuan, kos bilong wokman, 2,000 yuan na ol lus bilong kar i no wok, we i winim 20,000 yuan, i kamap bikos ol i no makim gut dispela model.
3.Praktikel Gaid bilong Seleksen
Sapos yumi tingim tripela bikpela samting olsem tempereja, oil kontaminesen na kos: AVSS em i gutpela long ol ples we i gat bikpela hat na oil (olsem ol ensin kompatimen na ol haidrolik ikwipmen), na AVS em i gutpela long ol nomol tempereja na drai senario (olsem ol kar na ol ilektronik samting insait long haus).
Long wankain taim, plis luksave:
Yu mas makim 'wire diameter' bihainim 'load current'. Long ol ikwipmen we i wok longpela taim, makim 60% bilong 'current-carrying capacity; long ol ikwipmen we i wok long sotpela taim, makim 60% i go inap 100%.
Ol i mas makim ol 'wiring harness' bilong kar bihainim kala kod spesifikesen bilong helpim luksave long en taim ol i mekim wok mentenens bihain.
Ol i save sekim 'current-carrying capacity bilong kondakta na 'line load' long rot bilong 'smoke emission curve' na ol 'simulation tools' bilong lukim olsem 'selection' i stap gut na i no gat hevi.
