Qhov tshwm sim ib nrab ntawm qhov paug tawm feem ntau yog hais txog qhov tshwm sim tawm los ntawm cov khoom siv hluav taws xob high-voltage. Raws li kev txheeb cais ntawm daim phiaj hluav taws xob, ib feem ntawm qhov tso tawm yog qhov laj thawj tseem ceeb rau kev puas tsuaj ntawm cov khoom siv hluav taws xob hluav taws xob siab thiab tseem yog ib qho tseem ceeb ntawm kev puas tsuaj ntawm rwb thaiv tsev. Tawm tawm uas tshwm sim hauv zos nyob rau hauv qhov kev txiav txim ntawm ib tug txaus muaj zog hluav taws xob teb nyob rau hauv lub rwb thaiv tsev ntawm lub hwj chim khoom. Qhov kev tso tawm no tsuas yog ua rau lub hauv paus luv luv (bridging) ntawm rwb thaiv tsev ntawm cov neeg xyuas pib yam tsis tau tsim txoj hauv kev. Txhua qhov tso tawm ib nrab yuav muaj qee qhov cuam tshuam rau qhov nruab nrab insulating. Ib qho me me tso tawm yuav muaj kev cuam tshuam me ntsis ntawm cov khoom siv hluav taws xob rwb thaiv tsev, thiab lub zog rwb thaiv tsev yuav txo qis; thaum ib feem muaj zog tawm yuav ua rau lub zog rwb thaiv tsev kom txo tau sai. Nws yog ib qho tseem ceeb uas ua rau muaj kev puas tsuaj rau cov khoom siv hluav taws xob siab. Yog li ntawd, thaum tsim cov rwb thaiv tsev ntawm cov khoom siv hluav taws xob high-voltage, nws yog ib qho tsim nyog yuav tau xav txog tias nyob rau hauv qhov kev txiav txim ntawm lub sij hawm ntev kev khiav hauj lwm voltage, muaj zog ib nrab tso tawm tsis tso cai rau tshwm sim nyob rau hauv lub rwb thaiv tsev qauv. Kev saib xyuas cov cuab yeej ua haujlwm yuav tsum muaj zog.
Thaum ib nrab tso tawm ntau tshaj ib theem, cov khoom siv yuav tsum tau muab tshem tawm ntawm kev ua haujlwm thiab tshuaj xyuas lossis hloov. Nyob rau hauv ib qho khoom dielectric nrog roj lossis kua, thaum lub zog hauv cheeb tsam ntawm cov roj los yog kua nrog lub zog tawg mus txog nws lub zog tawg, qhov no ntawm cov roj los yog kua pib tawm. Kev tso tawm ib nrab feem ntau yog tshwm sim los ntawm qhov tshwj xeeb hauv cheeb tsam hluav taws xob hauv cheeb tsam hauv ib qho insulator lossis ntawm nws qhov chaw. Feem ntau qhov tso tawm no tshwm sim raws li lub plawv dhia ntev dua 1 μs. Thaum ib nrab tso tawm tshwm sim hauv cov rwb thaiv tsev, lub neej ntawm cov rwb thaiv tsev yuav raug cuam tshuam. Txhua qhov tso tawm, qhov cuam tshuam ntawm cov hluav taws xob hluav taws xob siab lossis cov hluav taws xob nrawm, tshwj xeeb tshaj yog nyob rau lub sijhawm ntev, yuav ua rau muaj ntau yam teebmeem ntawm lub cev thiab tshuaj lom neeg. Piv txwv li, thaum ib tug nqi particle hits sab nrauv phab ntsa ntawm ib tug npuas, nws yuav ua txhaum lub insulating tshuaj daim ntawv cog lus thiab ua rau tawg. Ua kom puas cov qauv molecular ntawm rwb thaiv tsev, ua rau rwb thaiv tsev degradation thiab ua kom cov txheej txheem rwb thaiv tsev puas.
1. Kev tso tawm ib nrab yog ib qho kev qhia ntawm lub zos overheating thiab kev laus ntawm cov khoom siv hluav taws xob thiab cov khoom siv tshuab;
2. Qhov kev tso tawm ib nrab yog qhov nce ntxiv ntawm ib nrab tso tawm lub sijhawm. Qhov no yog txheej txheem tortuous. Nws tuaj yeem txo qis ntawm qee theem, tab sis nce ntawm qee theem;
3. Thaum ib nrab paug tshwm sim nyob rau hauv ib tug insulating qauv, nws yuav tau nrog rau cov tiam ntawm hluav taws xob pulses, ultrasonic tsis, electromagnetic tawg, lub teeb, tshuaj lom neeg cov tshuaj tiv thaiv, thiab lub zos cua sov;
Vim yog cov yam ntxwv saum toj no ntawm ib nrab tso tawm, yuav ua li cas kom tsis txhob muaj qhov paug tawm ib nrab thiab yuav ua li cas tshem tawm ib feem ntawm cov khoom siv hluav taws xob kom cov khoom siv tuaj yeem ua haujlwm tau zoo thiab nyab xeeb tau dhau los ua qhov tseem ceeb tshaj plaws rau cov khoom siv hluav taws xob tu cov neeg ua haujlwm. Txhawm rau tshem tawm qhov tshwm sim tsis txaus ntseeg no, ntau txoj hauv kev rau kev tshawb pom hauv online ntawm ib feem ntawm qhov tshwm sim tau muab los ntawm qee qhov hluav taws xob pulses, ultrasonic tsis, hluav taws xob hluav taws xob, thiab lwm yam teeb liab tsim nrog ib nrab tawm.
PDS800 handheld ib nrab tso tawm tester tsim los ntawm peb lub tuam txhab yog ib tug multi-functional handheld ntsuas uas kuaj pom ib feem ntawm cov khoom siv raws li nyob rau hauv av voltage, ultrasonic, ultrasonic, thiab high-frequency tam sim no nrhiav kom tau txoj kev; Nws yog tsim rau cov cables, Ib feem ntawm kev kuaj xyuas cov khoom siv hluav taws xob xws li GIS, hloov cov khoom siv thiab cov hloov pauv.
