Kev phom sij ntawm tib neeg lub cev hluav taws xob zoo li qub thiab nws cov kev tiv thaiv
1. Hluav taws xob poob siab
Hauv cov chaw uas cov av qis dua 40% RH, tib neeg lub cev yuav raug them ntau dua. Feem ntau, tib neeg lub cev raug them 2 txog 5kV. Qhov tso tawm qhov hluav taws xob uas ua rau tib neeg lub cev hnov hluav taws xob yog li 2 ~ 2.5kV. Thaum muaj hluav taws xob tshwm sim, tib neeg feem ntau yuav xav tias muaj teeb meem nrog hauv av lossis lub tsev (qauv) tsis yog hauv av. Qhov no yog kev xav ntau dua' lub tswv yim, vim tias tib neeg lub cev raug nqi yuav tso tawm thiab tsim tawm txawm nws yuav kov lub hauv paus lossis tsis nyob ib puag ncig (cais) tus neeg xyuas pib. hluav taws xob poob siab
Pom zoo ntsuas:
(1) Humidification, tsawg kawg 50%RH;
(2) Siv cov cua ion los tshem tawm tib neeg lub cev hluav taws xob zoo li qub;

(4) Txhim kho tib neeg lub cev cov cuab yeej tshem tawm zoo li qub uas tuaj yeem tiv thaiv hluav taws xob.
3. Tib neeg lub cev hluav taws xob zoo li qub hauv cov chaw petrochemical
Hauv qhov chaw txaus ntshai roj av, hluav taws xob zoo li qub ntawm tib neeg lub cev yog ib qho kev phom sij txaus ntshai tshaj plaws. Qhov laj thawj yog tias muaj ntau txoj hauv kev rau cov pa tso tawm thiab tib neeg lub cev kom raug them thiab tso tawm hauv kev lag luam; qhov thib ob yog tias feem ntau ntawm cov neeg ua haujlwm tsis nkag siab qhov txaus ntshai ntawm tib neeg lub cev hluav taws xob zoo li qub thiab cov kev ntsuas tshwj xeeb los tiv thaiv kev tso tawm hluav taws xob. Yuav luag txhua txoj cai hluav taws xob zoo li qub thiab txawv teb chaws tau tso tawm txoj cai los tiv thaiv tib neeg lub cev hluav taws xob zoo li qub, tab sis hmoov tsis zoo, feem ntau ntawm cov kev cai no tsis muaj kev ua haujlwm raws li kev txwv txaus ntshai thiab txwv tshwj xeeb, yog li muaj xwm txheej tshwm sim hauv cov tuam txhab ib ntus. Piv txwv li, xyoo 1972, tsheb nqaj hlau thauj khoom flash thiab hluav taws sib tsoo ntawm qee lub Hoobkas ntawm Fushun Petroleum, xyoo 1979 muaj hluav taws kub thiab tawg hluav taws sib tsoo hauv kev sib tsoo rhiav ntawm Xi' lub Hoobkas siv roj av los so hauv pem teb, Lub foob pob tawg thiab hluav taws sib tsoo ntawm lub tsheb hauv Yanshan xyoo 1983, thiab lub cev me me hauv Tianjin xyoo 1988 raws li PP Lub foob pob tawg tawg ntawm cov khoom ntim khoom, kev sib tsoo piv txwv ntawm Yongping Mine hauv 2000, lub tsheb ua kom tsis zoo ntawm cov roj chaw nres tsheb, qhov xwm txheej tawg ntawm kev nchuav hmoov rau hauv lub thawv, qhov teeb meem tawg ntawm qhov piv txwv nrog cov hlau me me, thiab lwm yam, txhua qhov xwm txheej no cuam tshuam ncaj qha rau tib neeg lub neej thiab khoom ntiag tug kev nyab xeeb. Cov hauv qab no tham txog cov yam ntxwv ntawm tib neeg lub cev nws tus kheej.
Tib neeg lub cev muaj peev xwm 100 ～ 400PF (ob peb tuaj yeem ncav cuag 1000PF), them 2 ～ 5kV tib neeg lub cev lub zog cia 0.4 ～ 2.5mJ (W=CV2/2, tib neeg lub cev muaj peev xwm suav tau ntawm 200PF); tib neeg lub cev tiv taus 500 ～ 5000Ω, sim ua pov thawj, simulated tib neeg lub cev Lub sijhawm tam sim no (kwv yees li kaum tawm ns) tso tawm lub zog hloov mus rau hauv av hlau lub cev yog siab li 80% txog 100%, uas yog txaus kom ua rau cov nplaim taws thiab cov pa tawg, roj thiab roj, thiab lwm yam (xws li H2*qhov hluav taws xob me me hluav taws xob tsawg dua 0.1mJ, cov pa roj av tsawg kawg nkaus lub zog hluav taws xob 0.26 mJ). Yog li ntawd, hauv cov tuam txhab roj av, muaj hluav taws thiab tawg ntau dua los ntawm hluav taws xob zoo li qub rau tib neeg lub cev. Nyiv' s&"Electrostatic Safety Guidelines &" tau cais cov tib neeg lub cev raws li tus neeg xyuas kev sib cais rau kev tswj hwm, nrog kev ntsuas ntsuas ntawm 100V.
