Kev Tiv Thaiv Kev Ntsuam Xyuas Ntawm Cov Khoom Muag Khoom Muag Khoom Muag

Kev tiv thaiv ntsuas ntawm lubfaib lub thawvenclosure yog ib qho ntawm nws qhov tseem ceeb tsis muaj kev nyab xeeb, siv los txiav txim siab nws lub peev xwm los tiv thaiv kev nkag ntawm cov khoom txawv teb chaws (xws li plua plav) thiab kua (xws li dej). Nws yog tus sawv cev thoob ntiaj teb los ntawm IP code.

I. Kev Tiv Thaiv Kev Ntsuas thiab Daim Ntawv Thov Scenarios rau Distribution Boxes

IP20: Qhuav hauv tsev ib puag ncig (xws li, chaw ua haujlwm, chav hluav taws xob hauv tsev, chav tswj). Qhov kev ntaus nqi feem ntau.

IP41 / IP40: Sab hauv tsev computer chav, ib puag ncig nrog cov av noo me ntsis.

IP54: Muaj ib puag ncig sab hauv tsev (piv txwv li, kev cob qhia, chaw noj mov thiab dej haus, chav ntxhua khaub ncaws), nrog plua plav, noo noo, lossis cov dej tawg.

IP55: Sab nraum zoov (nrog vaj tse) lossis qhov chaw nyob sab hauv tsev uas yuav raug ntxuav (piv txwv li, lub tsev sab nrauv, cov khoom siv platforms).

IP65: hnyav sab nraum zoov / kev lag luam ib puag ncig (ua kom tsis muaj plua plav, tiv taus qis- kev ntxuav dej), rau plua plav, ntub dej sab nraum zoov.

IP66: Qhov chaw sab nraum zoov hnyav (xws li, chaw nres nkoj, nkoj nkoj, thaj chaw uas nquag ntxuav nrog siab - dej siab).

IP67 / IP68: Ib puag ncig tshwj xeeb (xws li, cov qhov hauv av uas yuav raug dej nyab, cov kav dej, lossis cov dej hauv qab tag nrho).

Lus Cim: Hauv cov ntawv thov kev lag luam thiab kev lag luam feem ntau, IP54, IP55, thiab IP65 yog qhov kev ntsuas ntau tshaj plaws.

II. Yuav Ua Li Cas Xaiv Qhov Kev Tiv Thaiv Kev Ntsuas Zoo
Tus yuam sij rau kev xaiv yog nyob rau hauv qhov tseeb ntsuas qhov chaw nruab nrab ntawm lub thawv xa khoom.

1. Ib puag ncig sab hauv:
Ntxuav, qhuav: IP20 lossis IP40 txaus.

Plua plav, ntub dej, lossis ua rau cov dej tawg (xws li, cov chaw tsim khoom, nyob ze cov chav ua noj, chav dej): IP54 yog tus qauv xaiv.

Yuav tsum tau ntxuav thiab ntxuav (piv txwv li, kev cob qhia zaub mov thiab tshuaj): IP65 lossis siab dua.

2. Sab nraum zoov ib puag ncig:
Raug cua thiab nag: IP65 yog tus qauv pom zoo yam tsawg kawg nkaus rau kev siv sab nraum zoov.

Tej zaum yuav raug rau cov dav hlau dej muaj zog thiab yoj cuam tshuam: IP66 yuav tsum tau.

Tej zaum yuav raug tso rau hauv ib ntus (xws li, qis- thaj chaw pw): Xav txog IP67.

III. Cov ntsiab lus tseem ceeb

1. Sealing yog System Engineering txheej txheem:Txawm hais tias lub kaw lus nws tus kheej ncav cuag IP65, kev tiv thaiv yuav ua tsis tau zoo yog tias cov kab txuas txuas txuas (cov kab txuas txuas) tsis tau teeb tsa kom zoo, lossis yog tias lub qhov rooj foob muaj hnub nyoog / tsis kaw nruj nreem.

2. Sib npaug ntawm cov cua kub dissipation thiab kev tiv thaiv:Kev tiv thaiv siab dua (piv txwv li, IP66) muab kev sib khi zoo dua, tab sis ua kom cov cua sov dissipation nyuaj dua. High-cov ntaub thaiv npog feem ntau xav tau cov kiv cua txias, cua txias, lossis cov khoom siv hluav taws xob.

3. Ua raws li cov qauv:Xyuas kom cov khoom ua raws li IEC 60529 lossis GB / T 4208 tus qauv kom ntseeg tau tias nws qib kev tiv thaiv nominal ntseeg tau tiag tiag.

4. Xav txog qhov ua tau zoo thiab zam dhau -kev tshaj tawm:Xaiv cov qib kev tiv thaiv tsim nyog raws li qhov chaw ib puag ncig tiag tiag; Kev tiv thaiv siab heev yuav ua rau cov nqi tsis tsim nyog.

Kev tiv thaiv qib ntawm lub thawv xa khoom ncaj qha cuam tshuam rau cov neeg ua haujlwm kev nyab xeeb, khoom siv lub neej ntev, thiab kev ntseeg siab ntawm cov khoom siv hluav taws xob. Thaum xaiv, nws yog ib qho tseem ceeb kom nkag siab txog cov plua plav concentration, av noo, thiab hom thiab siab ntawm cov dej uas tuaj yeem cuam tshuam nrog ib puag ncig. Thaum lub sij hawm installation, xyuas kom meej tag nrho cov ntsiab lus sealing nyob rau hauv qhov chaw kom ntseeg tau tias nws muaj kev tiv thaiv zoo.
