Kodi Chingwe Chotetezedwa ndi Chiyani Ndipo N’chifukwa Chiyani Kuteteza N’kofunika?
- Yankho Lolunjika: Gawo Loteteza Zizindikiro Zomvera
Anthu nthawi zonse amafunsa kuti:"Kodi chingwe choteteza zida ndi chiyani?"
Yankho losavuta:Chingwe chotchinga ndi chingwe chomwe chili ndi gawo lina lowonjezera la conductive — nthawi zambiri chopangidwa ndi aluminiyamu, choluka cha mkuwa, kapena zonse ziwiri — chozunguliridwa ndi ma conductor otetezedwa. Chingwe ichi chimagwira ntchito ngati chotchinga, kuteteza zizindikiro zoyezera mkati kuchokera ku kusokoneza kwa ma electromagnetic (EMI) ndi kusokoneza kwa ma radio-frequency (RFI).
Chifukwa Chake Kuteteza Kuli Kofunika:

| Zingwe zomwe zikuyenda motsatira zingwe zamagetsi | Mphamvu yamagetsi yoyambitsidwa imayambitsa zolakwika muyeso | Chishango chimachotsa phokoso loyambitsidwa pansi |
| Zipangizo zowotcherera pafupi | Kusokoneza kwakukulu kumawononga kulankhulana kwa digito | Chishango chimateteza zizindikiro zowongolera zofunika kwambiri |
| Phokoso lamagetsi la zomera zonse | Chiŵerengero cha chizindikiro-ku-phokoso chimachepa → kulondola kochepa | Chishango chimasunga umphumphu wa chizindikiro |
Mfundo Yofunika Kwambiri:M'malo opangira mafakitale, zingwe zosatetezedwa zimakhala zosavuta kukhudzidwa ndi phokoso lomwe lingapangitse kuti ma loops a 4-20mA asagwire bwino ntchito, zomwe zimapangitsa kuti kuwerenga kwa RTD kusinthe, komanso kuwononga mauthenga a digito monga RS485 kapena Modbus.
Pa Dingzun Cable,Timapanga zingwe zotchingira zotchingira zokhala ndi zojambulazo, zoluka, ndi zotchingira zophatikizika — zomwe zimapangidwa mogwirizana ndi malo anu enieni a EMI komanso zofunikira pakuzindikira zizindikiro.
