Kutheni umhloli wokumelana nomhlaba kufuneka akhuphe i-electrode ukusuka ngaphakathi

Ezinye izixhobo zokulinganisa ukuxhathisa zifuna ukuqhawulwa komlinganiselo, ngelixa ezinye azikwenzi, ikakhulu ngenxa yezi ngqwalasela zilandelayo.Ukuba azinqanyulwanga, iimeko ezilandelayo ziya kwenzeka:

                     I-HV Hipot GDCR3200C ibambe iqhosha eliphindwe kabini le-multi-function grounding resistance tester

1. Ukuba ukuchasana kokumisa i-electrode phantsi kovavanyo kukhulu kakhulu okanye ucingo luphukile phantsi komhlaba, umthombo wangoku okanye i-generator kwisixhobo sokulinganisa uya kuvuleka, kwaye ke i-voltage yesiphaluka evulekile iya kuqhutyelwa kwi-casing yesixhobo sangaphakathi. kunye nezixhobo ngokusebenzisa inkqubo yangaphakathi yokumisa.I-voltage evulekileyo yesekethe yejeneretha ye-cranked yesandla ngokubanzi ingaphezulu kwe-100V, kwaye i-voltage evulekileyo yesekethe yomthombo wangoku webhetri ingaphantsi kwe-50V.
2. Ukuba izixhobo zombane zangaphakathi zivuza ngoku, i-current iya kujojowe kwi-electrode evavanyiweyo emhlabeni, kwaye i-voltage drop drop iya kuveliswa kumhlaba ojikelezayo, obizwa ngokuba yi-ground voltage.Ukuba i-voltage yomhlaba incinci, iya kuchaphazela umphumo wokulinganisa, kwaye ukuba i-voltage yomhlaba inkulu, iya kusongela ukhuseleko lwabasebenzi okanye yonakalise ukuchasana komhlaba.umphezulu.
3. Ezinye iindlela ezingaqhelekanga zokumisa phantsi zidibanisa iinkqubo ezimbini ezizimeleyo ezizimeleyo ngokusebenzisa i-casing yesixhobo kunye nezixhobo.Ixabiso lokuchasana elilinganiswe imitha yokumelana nomgangatho alukho uxhathiso olulodwa lokumisa, kodwa uxhulumaniso oluhambelanayo lweendlela ezimbini zokuxhathisa.Nangona i-electrode yomhlaba phantsi kovavanyo iphukile, ayikwazi ukufunyanwa.
Kungcono ukuqhawula ucingo lomhlaba xa ulinganisa ukuchasana komhlaba.Ukuba akunjalo, nikela ingqalelo ukuphepha le meko ingasentla, kwaye wenze:
(1) Linganisa amandla ombane asemhlabeni kuqala.Ukuba i-voltage yomhlaba yamanqaku E no-C inkulu kuneemfuno zesixhobo sokulinganisa, cima izixhobo zombane ezifanelekileyo, kwaye ucime umbane xa kuyimfuneko.
(2) Khangela kwaye uqinisekise ukuba i-electrode ephantsi kovavanyo isekelwe kakuhle, khangela uxhulumaniso lweenkqubo ezimbini ezizimeleyo ezizimeleyo, kwaye ungabandakanyi iindawo ezisezantsi ezingaqhelekanga.Namhlanje, inkqubo yokumisa ngokuqhelekileyo iyadingeka ukwabelana nge-electrode yomhlaba, ngoko akukho zimbini ze-electrodes ezizimeleyo zomhlaba, kwaye imeko yoxhumo lwangaphandle ayiqwalaselwa.Ukukhangela iingcingo ezaphukileyo, linganisa ukuxhathisa kwe-loop.
