Prinsip "Single-Point Grounding" ga Wani Ingantaccen Sistemar Inganci

1. Fassara na “Single-Point Grounding”

Single-point grounding yana nufin kungiyar da ya shiga cikin wani wurin da aka taka da lafiya a matsayin mafi girma, inda jami'ar abubuwa masu lalace-tsukeni suna da tsari daga harkokin lafiya. Idan an yi amfani da kalmar "single-point grounding" yana nufin cewa idan akwai "kungiya" da abubuwan da suka haɗa da ita ne suna da tsari, wannan mafi girma (ko mafi girma na kungiyar) yana buƙata da lafiya a matsayin mafi girma.

Misali, a cikin kungiyar haraji na optical fiber: mafi girman multi-channel optical transmitters yana da muhimmanci a matsayin mafi girma na kungiyar. Akan gine suka buƙata da lafiya a matsayin mafi girma, amma duka kamirun da suka haɗa da su ne a kan cables suna da tsari daga harkokin lafiya. Wannan yana cika a matsayin "single-point grounding" a cikin kungiya da suka haɗa da ita ne. Buƙatar mafi girman mafi girma ba zan iya canza wannan ba saboda optical fiber yana bayyana tsari daga harkokin lafiya.

2. Muhimmancin Ingantaccen Don "Single-Point Grounding"

Mafi girman mafi girma yana buƙata da lafiya a matsayin mafi girma, amma duka abubuwan da suka haɗa da ita ne suna da tsari daga harkokin lafiya. Tsarin lafiya da ke faruwa a cikin kungiya zai faruwar da ita a matsayin mafi girma, don in samun tsari mai kyau da lafiya don in ba da inganci a rayuwa.

Ba a yi single-point grounding, "tsari na lafiya" na kungiya yana nufin tsari na kungiya daga harkokin lafiya—yanayi, tsari a matsayin mafi girma na kungiya.

A cikin tsohon fadin siffofin lafiya, wasu masu ilimi sun ce ake amfani da kalmar "overvoltage" ko "high potential" don in bayyana tsarin lafiya da ke faruwa a kan cables, sun ce ake buƙata da surge protectors a duk biyu daga hankalin cable zai iya canza biyu daga hankali zuwa hankali na mata.

Amma, bayanan aiki na tsari mai kyau yana nuna cewa idan ake amfani da voltage-limiting surge protectors a duk biyu daga hankalin cable, amsa a matsayin mafi girma zai iya zama "equal in magnitude but opposite in polarity." Ba zan iya samun tsari mai kyau ba. Duk da haka, "tarihin faruwa zuwa lafiya" yana da AC/DC impedance na cable da kuma tarihin lafiya, amma babu tsari mai kyau. Tushen "effective diversion of lightning current" a cikin hakan ba zan iya faruwa ba.

Tsarin lafiya da ke faruwa a kan cables ba da alaka da lafiya, ba zan iya faruwa lafiya zuwa lafiya. "Single-point grounding" ana iya amfani da ita don in faruwa tsarin lafiya a cikin kungiya, ba zan iya buƙata da tsari mai kyau ko tarihi mai girma. Yana da yanayi da lightning rod grounding, power system grounding, ko surge protector grounding da ke amfani da ita don in faruwa lafiya mai yawa. Aiki da wire na musamman don in buƙata da building rebar ko water pipe yana daidai.

3. Bincike na Dalilai na "Single-Point Grounding"

"Single-point grounding" yana ɓoye duka ground loops, yana ɓoye tarihin faruwar da "lightning-induced ground potential" da kuma "power grid ground potential" zuwa low-voltage electronic systems. Wannan yana da muhimmanci ga aiki na protection against lightning, surge suppression, da kuma interference prevention.

Na'am, multi-point grounding yana faruwa ground potential interference, power grid surges, da kuma lightning back-flash voltages. Wasu misalai a cikin fadin siffofin lafiya sun nuna cewa multi-point grounding yana iya canza waɗannan abubuwa da kuma surge protectors.

"Single-point grounding" a cikin security systems yana da muhimmanci ga aiki na protection against induced lightning—wannan yana da muhimmanci ga aiki na proper lightning protection design a cikin hakan.

Lightning strikes ba zan iya faruwa lafiya zuwa lafiya, ba zan iya buƙata da wani abu na kungiya don in faruwa lafiya. Protection against induced lightning yana buƙata da protective circuits don in canza tsari na equipment ports zuwa tsari mai kyau. Wadannan protective circuits ba zan iya buƙata da lafiya.

Idan ake yi "single-point grounding," duka kungiya yana da tsari sama da matsayin mafi girma. Babu tsari mai kyau a matsayin mafi girma a cikin wide-area information systems.

In yi amfani da "single-point grounding" safety design principle yana taimakawa in ba da shawarwari game da "grounding-based lightning protection" da kuma in ba da shugaban aiki da tarihi mai girma.
