Kwisanti, i-rock pan kunye neminye imihlaba ene-resistivity enkulu yomhlaba, ukwenzela ukuhlangabezana neemfuno eziphantsiukubeka phantsi komhlabaukumelana, isiseko

igridi eyenziwe ngamaqela amaninzi asezantsi ngokunxuseneyo isoloko isetyenziswa.Nangona kunjalo, ngamanye amaxesha zininzi izinto zentsimbi ezifunekayo kunye ne

indawo yokumisa inkulu kakhulu, ngoko kudla ngokuba nzima ukufezekisa ukuxhathisa okufunekayo.Ngeli xesha, sinokuzama ukunciphisa umhlaba

resistivity yomhlaba kufuphi nomzimba womhlaba, kunye nokufezekisa injongo yokunciphisa ukuchasana komhlaba.

1. Sebenzisa umhlaba ongaxhathisiyo (oko kukuthi indlela yokubuyisela umhlaba)

Udongwe, i-peat, umhlaba omnyama kunye nodongwe lwesanti zisetyenziselwa ukutshintsha umhlaba wokuqala kunye ne-coefficient yokumelana nombane, kunye ne-coke kunye namalahle.

inokusetyenziswa kwakhona ukuba kuyimfuneko.Uluhlu lokutshintshwa yi-1 ~ 2m ukujikeleza i-electrode yokumisa kunye ne-1/3 ye-electrode yokumisa kwindawo

kufutshane necala lomhlaba.Emva konyango olunjalo, ukuxhathisa umhlaba kunokuncitshiswa malunga ne-3/5 yexabiso lokuqala.

2. Unyango olungeyonyani olunjengokufaka ityuwa

Yongeza ityuwa, i-coal cinder, i-carbon dust, i-furnace ash, i-coke ash, njl.

Eyona nto isetyenziswa kakhulu yityuwa.Ngenxa yokuba ityuwa inefuthe elihle ekuphuculeni ukuxhathisa umhlaba, ayixhomekekanga kwixesha lonyaka

utshintsho,kwaye ixabiso liphantsi.Indlela yonyango kukwemba umngxuma onobubanzi obungange-0.5 ~ 1.0m ukujikeleza umzimba ngamnye wokumisa, kwaye ugcwalise

ityuwa nomhlabakumaleko womngxuma ngokomaleko.Ngokuqhelekileyo, ubukhulu bomaleko wetyuwa bumalunga ne-1cm, kwaye ubukhulu bomhlaba bumalunga ne-10cm.Umaleko ngamnye

yetyuwa kufunekaimanziswe ngamanzi.Ukusetyenziswa kwetyuwa ye-tubular grounding body malunga ne-30-40kg;Le ndlela inokunciphisa isiseko

ukumelana neoriginal (1/6-1/8) kumhlaba oyisanti kunye (2/5-1/3) kudongwe lwesanti.Ukuba ungeze malunga ne-10kg yamalahle, umphumo uya kuba ngcono.Njengamalahle

yinto eqinileyoi-conductor, ayiyi kuchithwa, ingene kwaye igxumeke, ngoko ixesha layo elisebenzayo lide.Kwintsimbi yentsimbi, intsimbi ejikelezayo kunye nezinye izinto ezihambelanayo

ukubeka phantsi komhlabaimizimba, iziphumo ezingcono zinokufumaneka ngokusebenzisa ezi ndlela zingasentla.Nangona kunjalo, le ndlela nayo inezingeloncedo, njengesiphumo esincinci

ematyeni kunyeumhlaba onamatye amaninzi;Ukuzinza komzimba womhlaba kuncitshisiwe;Iya kukhawulezisa ukubola komzimba womhlaba;Umhlaba

Ukuchasa kuya kuba njalongokucothayo ukwanda ngenxa yokunyibilika kancinci kunye nokulahleka kwetyuwa.Ngoko ke, kufuneka iphathwe kanye malunga neminyaka emi-2 emva konyango lwezandla.

3. Ngaphandleukubeka phantsi komhlaba

Ngokukodwa kwiindawo ezisezintabeni, xa ixabiso lokuxhathisa umhlaba kufuneka libe lincinci kwaye kube nzima ukufikelela kwindawo, ukuba kukho umthombo wamanzi okanye

umhlaba one-coefficient ephantsi yokumelana kufuphi, indawo ingasetyenziselwa ukwenza i-electrode yomhlaba okanye ukubeka igridi yokumisa phantsi kwamanzi.Emva koko, sebenzisa

ucingo lokumisa (olufana nentsimbi ecwecwe) ukuyidibanisa njengesiseko sangaphandle.Nangona kunjalo, kufuneka kuqatshelwe ukuba isiseko sangaphandle

isixhobo kufuneka sithintele umjelo wabahambi ngeenyawo ukunqanda ukothuka kombane okubangelwa yinyathelo lombane;Xa uwela uhola wendlela, ubunzulu obungcwatywe

ukhokelo lwangaphandle aluyi kuba ngaphantsi kwe-0.8m.

4. Ikhonkrithi eqhubayo

I-carbon fiber ixutywa kwisamente ukuze isetyenziswe njenge-electrode yokumisa.Umzekelo, malunga ne-100kg ye-carbon fiber yongezwa kwi-1m3 yesamente

ukwenza i-hemispherical (1m ububanzi) i-electrode yokumisa.Ngokusebenzisa umlinganiselo, amandla ayo okumisa amandla okuxhathisa (xa kuthelekiswa

ngesamente eqhelekileyo) ingancitshiswa ngokubanzi malunga ne-30%.Le ndlela isoloko isetyenziselwa ukukhuselwa kombane kunye nezixhobo zokumisa.Kwi

ukuze unciphise ngakumbi ukunyanzeliswa kokumisa impembelelo, inaliti eyenziwe ngenaliti yokumisa i-electrode inokufakwa kwi-conductive.

ikhonkrithi ngaxeshanye, ukwenzela ukuba i-corona yokukhupha ikwazi ukuqhubeka nokugalela amaza kunye ne-carbon fiber ukusuka kwincam yenaliti, ene-

isiphumo esicacileyo ekunciphiseni ukunyanzelwa komhlaba ukuxhathisa.

5. Unyango lwekhemikhali kunye ne-arhente yokunciphisa i-drag

I-ejenti yokunciphisa i-agent esebenzisa i-carbon powder kunye ne-quicklime njengezona zixhobo eziphambili zingasetyenziswa emhlabeni ixesha elide kwaye ziya

ayinakulahleka ngenxa yamanzi aphantsi komhlaba kuba ayinayo i-dielectric, ngoko ke inokufumana indawo ephantsi yongcoliseko yexesha elide kunye nezinzileyo ephantsi.

ukuchasana (malunga ne-1/2 ngaphantsi kunaleyo ngaphambi kokusebenzisa i-arhente yokunciphisa ukuchasana ukunyanga umhlaba).Kwindawo yepleyiti elukhuni, indlela ye

ukungcwaba ucingo lokumisa kunye ne-arhente yokunciphisa ukuxhathisa iyasebenza kakhulu, kwaye ukuxhathisa kwayo phantsi kunokwehliswa malunga ne-40% xa kuthelekiswa.

naleyo yokungcwaba kuphela ucingo lokumisa.Ukongeza, le ndlela inokufezekisa iziphumo ezilungileyo nje ngokuba ngumgubo wokunciphisa i-arhente yokunciphisa okanye

i-arhente yokunciphisa ixesha elide ifafazwe emseleni wembiwa kwaye ibekwe ngocingo lokumisa, kwaye umhlaba omdala ugcwaliswe.

6. Indlela yokungcwaba iqula elinzulu

Le ndlela iye yaxelwa kumazwe angaphandle ixesha elide, kwaye iphumelele iziphumo ezilungileyo ekusebenziseni okusebenzayo.Kwiminyaka yakutshanje, iTshayina nayo

uqalise ukusebenzisa le ndlela intsha yokunciphisa uxhathiso.Ubude bomzimba wokumisa othe nkqo osetyenziswe kule ndlela ngokuqhelekileyo yi-5 ~ 10m

ngokuxhomekeke kwiimeko zejoloji.Ukuba lide, umphumo awuyi kubonakala kwaye ukwakhiwa kuya kuba nzima.Isiseko

umzimba ngokuqhelekileyo wamkela Φ 20 ~ 75mm intsimbi engqukuva.Impembelelo yentsimbi ejikelezayo enobubanzi obuhlukeneyo kwi-grounding resistance is very

encinci.Le ndlela isetyenziswa kwizakhiwo ezixineneyo okanye kwiindawo ezimxinwa apho kubekwe khona iigridi zomhlaba.Kwezi meko, kunzima ukuba

fumana indawo efanelekileyo yokungcwatywa kwe-electrode yomhlaba kunye neendlela zendabuko, kwaye umgama okhuselekileyo awunakuqinisekiswa.Nangona i

ukhuseleko lunokuqinisekiswa ngokugubungela umzimba womhlaba kunye ne-asphalt insulating layer, umthwalo wokwakha kunye neendleko zofakelo.

anda.Indlela yokungcwaba nzulu yeyona ndlela isebenzayo kumhlaba wesanti, kuba uninzi lwamaleko anesanti akumaleko womphezulu.

ngaphakathi kwe-3m, ngelixa ukumelana komhlaba kumaleko anzulu kuphantsi.Ukongeza, le ndlela iyasebenza nakwiindawo zeepleyiti zamatye.

Ngexesha lokwakha Φ Umatshini omncinci we-auger okanye umatshini wokomba onobubanzi obuyi-50mm nangaphezulu.Ungcwatywe kumngxuma ogrunjiweyo Φ 20 ~ 75mm

umzimba wentsimbi engqukuva, kwaye emva koko uzaliswe ngodaka lwekhabhoni (exutywe nekhabhoni fayibha yamanzi ludaka) okanye ludaka.Ekugqibeleni, iziseko ezininzi

imizimba enonyango olufanayo idityaniswe ngokunxuseneyo ukwenza umzimba osisiseko opheleleyo.Umzimba womhlaba owenziwe ngale ndlela

ayichatshazelwa kangako ngamaxesha onyaka kwaye inokufumana ukuxhathisa okuzinzileyo.Ngexesha elifanayo, ngenxa yokungcwaba okunzulu, i-voltage yesinyathelo nayo ingaba

kuncitshiswe kakhulu, nto leyo eluncedo kakhulu ekukhuseleni ukhuseleko lomntu.Le ndlela ilungele ukwakhiwa, ixabiso eliphantsi kunye

iphawuleka ngokusebenzayo, eya kuthi yaziwe kwaye isetyenziswe.
