Kev Txhim Kho Grounding Wires - Blog

Cov txheej txheem rau kev txhim kho cov kab hauv av: Lub hauv paus ntsiab lus tseem ceeb ntawm kev txhim kho cov xaim hauv av yog "txuas cov av kawg ua ntej, tom qab ntawd tus neeg xyuas pib kawg" (ie, txuas rau lub ntiaj teb ua ntej, ces kab). Kev tshem tawm yog qhov sib txawv kiag li. Qhov no yog los tiv thaiv lub zog tam sim ntawd los yog cuam tshuam tam sim no los ntawm kev tawm ntawm tib neeg lub cev thaum ua haujlwm, ua kom cov neeg siv kev nyab xeeb.

Standard Operating Sequence (Installation)

1) Kev ntsuas hluav taws xob: Ua ntej txhim kho cov xaim hauv av, tus ntsuas hluav taws xob tsim nyog ntawm qhov ntsuas hluav taws xob tsim nyog yuav tsum tau siv kom paub meej tias cov khoom siv lossis kab tsis muaj qhov hluav taws xob. Qhov no yog qhov yuav tsum tau ua ua ntej; qhov muag tsis pom kev ua haujlwm raug txwv nruj heev.

2) Txuas qhov kawg ntawm Grounding: Ua ntej, txhim khu kev qha txuas ib kawg ntawm cov xaim hauv av mus rau hauv daim phiaj hauv av lossis cov ceg av qab teb (qhov kev tiv thaiv hauv av yuav tsum tsim nyog).

3) Txuas tus neeg xyuas pib kawg: Siv lub pas nrig insulated (kev ua haujlwm qib), txuas rau lwm qhov kawg ntawm cov xaim hauv av mus rau peb theem conductors ntawm de- cov khoom siv zog, ua kom muaj kev sib cuag zoo thiab ruaj ntseg.

Sequence of Grounding Operations

Installation Sequence nyob rau hauv Complex Scenarios

Rau ntau- cov kab hluav taws xob txheej tsim los ntawm tib lub pej thuam, cov kab lus hauv qab no yuav tsum tau ua raws li kev tiv thaiv hluav taws xob los yog kev raug mob arcing:

Tsawg voltage ua ntej, ces high voltage.

Cov txheej txheem qis dua ua ntej, tom qab ntawd txheej sab saud.

Sab ze tshaj plaws ua ntej, ces sab tshaj plaws.

Kev tshem tawm ib ntus (Ua tiav qhov thim rov qab ntawm kev teeb tsa)

1. Disconnect tus neeg xyuas pib kawg: Ua ntej, tshem cov clamps txuas nrog cov khoom siv los yog kab neeg xyuas pib.

2. Disconnect grounding kawg: Thaum kawg, tshem tawm cov clamps txuas nrog rau daim phiaj hauv av.

3. Rov qab: Tam sim ntawd tom qab tshem tawm, khaws cov cuab yeej, sau tseg, thiab tshaj tawm.

Critical Safety Red Lines

Yuav tsum muaj ob-tus neeg ua haujlwm: ib tus neeg saib xyuas, thiab ib tus neeg ua haujlwm. Thaum ua haujlwm ib leeg, tsuas yog cov hloov pauv hauv av tau tso cai.

Hnav cov iav tiv thaiv: Cov hnab looj tes insulating thiab insulated rods yuav tsum tau hnav thaum ua haujlwm. Tib neeg kev sib cuag nrog cov xaim hauv av lossis cov neeg ua haujlwm tsis muaj av yog txwv nruj.

Tsis muaj wrapping: Grounding xov hlau yuav tsum tau ruaj nrog rau siab clamps. Wrapping yog txwv tsis pub siv rau hauv av lossis luv luv -circuiting.

Mnemonic Rhymes

Kev teeb tsa: Hauv pem teb ua ntej, tom qab ntawd tus neeg xyuas pib (duab lub davhlau ya nyob twg ua ntej, tom qab ntawd lub davhlau ya nyob twg)

Kev tshem tawm: Tshem tawm tus neeg xyuas pib ua ntej, tom qab ntawd lub davhlau ya nyob twg hauv av (tshwj xeeb yog qhov thim rov qab ntawm kev teeb tsa kev txiav txim)

VTZ-12KF Nqus Circuit Court Breaker
