Mujecha, pani yedombo uye mamwe mavhu ane hombe yepasi resistivity, kuitira kuti isangane nezvinodiwa zvepasigroundingkuramba, a grounding

grid inoumbwa nemitumbi yakawanda yekugadzika yakafanana inowanzoshandiswa.Zvisinei, dzimwe nguva zvinhu zvakawanda zvesimbi zvinodiwa uye

grounding nzvimbo yakakura kwazvo, saka kazhinji zvakaoma kuwana inodiwa grounding kuramba.Panguva ino, tinogona kuedza kuderedza pasi

resistivity yevhu pedyo nemuviri wepasi, uye zvakare kuzadzisa chinangwa chekudzikisa pasi pasi.

1. Shandisa ivhu rakaderera rekudzivirira (kureva nzira yekutsiva ivhu)

Ivhu, peat, ivhu dema uye ivhu rejecha rinoshandiswa kutsiva ivhu rekutanga nepamusoro pemagetsi kuramba coefficient, uye coke uye marasha.

inogonawo kushandiswa kana zvichidiwa.Iyo yekutsiva siyana ndeye 1 ~ 2m yakatenderedza electrode yepasi uye 1/3 yegirodhi yepasi pa

pedyo nerutivi rwepasi.Mushure mekurapa kwakadaro, kupikisa kwepasi kunogona kuderedzwa kusvika kune 3/5 yehuwandu hwepakutanga.

2. Artificial treatment sekuwedzera munyu

Wedzera munyu, coal cinder, kabhoni guruva, muto wevira, coke ash, nezvimwewo kune ivhu rakatenderedza muviri wepasi kuti uvandudze conductivity yevhu.

Inonyanya kushandiswa imunyu.Nekuti munyu une mhedzisiro yakanaka pakuvandudza ivhu rekudzivirira coefficient, ishoma pasi pemwaka

shanduko,uye mutengo wakaderera.Nzira yekurapa ndeyekuchera gomba rine dhayamita rinosvika 0.5 ~ 1.0m kutenderedza muviri wega wega wepasi, uye kuzadza

munyu nevhumugomba layer by layer.Kazhinji, ukobvu hwemunyu hunoita 1cm, uye ukobvu hwevhu hunosvika 10cm.Imwe neimwe layer

yemunyu inofanira kuvayakanyoroveswa nemvura.Kushandiswa kwemunyu kwetubular grounding body inenge 30-40kg;Iyi nzira inogona kuderedza pasi

resistance kuneyepakutanga (1/6-1/8) yevhu rejecha uye (2/5-1/3) yevhu rejecha.Kana iwe ukawedzera nezve 10kg marasha, mhedzisiro ichava nani.Semarasha

yakasimbaconductor, haizonyungudika, yakapinda uye yakasvibiswa, saka nguva yayo inoshanda yakareba.Yesimbi yakatsetseka, simbi yakatenderera uye zvimwe zvakafanana

groundingmiviri, migumisiro iri nani inogona kuwanikwa kuburikidza nekushandisa nzira dziri pamusoro apa.Zvisinei, nzira iyi inewo zvipingamupinyi, zvakadai semagumisiro mashoma

pamatombo uyeivhu rine matombo akawanda;Kugadzikana kwemuviri wepasi kunoderedzwa;Ichamhanyisa kukora kwemuviri wepasi;Pasi

kuramba kuchaitakuwedzera zvishoma nezvishoma nekuda kwekunyungudika zvishoma nezvishoma uye kurasikirwa kwemunyu.Naizvozvo, inoda kurapwa kamwe chete makore maviri mushure mekurapa nemawoko.

3. Kunzegrounding

Kunyanya munzvimbo dzine makomo, apo kukosha kwekudzivirira kwepasi kunodiwa kuve diki uye kunetsa kusvika mu situ, kana paine sosi yemvura kana

ivhu rine low resistance coefficient padyo, nzvimbo yacho inogona kushandiswa kugadzira grounding electrode kana kuisa pasi pemvura grounding grid.Zvadaro, shandisa

waya yepasi (yakadai sesimbi yakatsetseka) kuti ibatanidze senzvimbo yekunze.Zvisinei, zvinofanira kucherechedzwa kuti zvokunze grounding

mudziyo unofanirwa kudzivirira nzira yevanofamba netsoka kudzivirira kuvhunduka kwemagetsi kunokonzerwa nedanho voltage;Pakuyambuka mugwagwa, kudzika kwakadzika kwe

mutobvu wekunze uchange usingasviki 0.8m.

4. Conductive kongiri

Carbon fiber inosanganiswa kuita simende kuti ishandiswe semagetsi ekuisa pasi.Semuenzaniso, inenge 100kg ye carbon fiber inowedzerwa mu 1m3 ye simenti

kugadzira hemispherical (1m dhayamita) yekugadzika electrode.Kuburikidza nechiyero, simba rayo frequency grounding kuramba (kuenzanisa

nekongiri yakajairika) kazhinji inogona kudzikiswa ne30%.Iyi nzira inowanzoshandiswa pakudzivirira mheni uye midziyo yekumisa pasi.In

kuitira kuti uwedzere kudzikisira kupokana kwepasi, iyo tsono yakaumbwa yepasi electrode inogona zvakare kunyudzwa mune conductive.

kongiri panguva imwe chete, kuitira kuti corona yekuburitsa inogona kuramba ichivhuvhuta uye kabhoni fiber kubva kune tsono tip, iyo ine

mhedzisiro iri pachena pakudzikisa kupesvedzera grounding kuramba.

5. Kurapa kwemakemikari nekukwevera kuderedza mumiririri

Iyo inodzivirira inoderedza mumiriri uchishandisa kabhoni poda uye quicklime sezvo huru mbishi zvinhu zvinogona kushandiswa muvhu kwenguva yakareba uye ichaita.

kwete kurasika nekuda kwemvura yepasi nekuti haina dielectric, saka inogona kuwana kusvibiswa-isina kusvibiswa uye kugadzikana kwakadzika pasi pasi.

kuramba (inenge 1/2 yakaderera pane iyo isati yashandisa inodzikisira mumiririri kurapa ivhu).Kune hard rock plate zone, nzira ye

kuviga waya yekumisa uye kuramba kudzikisa mumiririri inoshanda chaizvo, uye kuramba kwayo kwepasi kunogona kudzikiswa neinosvika 40% zvichienzaniswa.

neicho chekuviga waya yekudzika chete.Mukuwedzera, iyi nzira inogona kuwana zvibereko zvakanaka chero bedzi powdery resistance inoderedza mumiririri kana

refu-kuita kushorwa kuderedza mumiririri inosaswa mugoronga akacherwa uye akaradzikwa negrounding waya, uye ipapo ivhu yekare iri backfilled.

6. Borehole deep burial method

Iyi nzira yakashumwa kune dzimwe nyika kwenguva yakareba, uye yakawana migumisiro yakanaka mukushandiswa kunoshanda.Mumakore achangopfuura, China zvakare

akatanga kushandisa nzira itsva iyi yekuderedza kuramba.Kureba kweiyo vertical grounding body inoshandiswa nenzira iyi kazhinji 5 ~ 10m

zvichienderana nemamiriro ezvinhu e geological.Kana yakareba, mugumisiro hauzove wakajeka uye kuvaka kuchava kwakaoma.The grounding

muviri unowanzo tora Φ 20 ~ 75mm simbi yakatenderera.Kupesvedzera kwesimbi yakatenderedza ine madhayamita akasiyana pakupikisa kwepasi kwakanyanya

diki.Iyi nzira inoshandiswa kune zvivakwa zvakatsvikinyidzana kana nzvimbo dzakamanikana uko magidhi epasi anoiswa.Mumamiriro ezvinhu aya, zvakaoma kuita

tsvaga nzvimbo yakakodzera yekuvigwa yekumisa electrode nemaitiro echinyakare, uye nzvimbo yakachengeteka haigone kuvimbiswa.Kunyangwe iyo

chengetedzo inogona kuoneswa nekuvhara muviri wepasi neasphalt insulating layer, basa rekuvaka uye mari yekuisa iri.

yakawedzera.Nzira yekuviga yakadzika ndiyo nzira inonyanya kushanda yevhu rejecha, nekuti mazhinji ejecha rayo ari muvhu repamusoro.

mukati me3m, nepo ivhu resistivity munzvimbo yakadzika yakaderera.Mukuwedzera, iyo nzira inoshandawo kune matombo ematombo ematombo.

Panguva yekuvaka Φ Diki rekushandisa auger kana muchina wekuchera une dhayamita ye50mm zvichikwira.Kuvigwa mugomba rakacherwa Φ 20~75mm

simbi yakatenderedza muviri wepasi, wobva wazadzwa nekabhoni dhaka (yakavhenganiswa nekabhoni fiber mvura inotsvedza) kana slurry.Pakupedzisira, akawanda grounding

miviri ine mabatirwo akafanana inobatanidzwa mukufambirana kuita muviri wakakwana wepasi.Muviri wepasi wakagadzirwa neiyi nzira

haina kukanganiswa nemwaka uye inogona kuwana yakagadzikana yepasi kuramba.Panguva imwecheteyo, nekuda kwekuvigwa kwakadzika, danho remagetsi rinogonawo kuva

yakaderedzwa zvakanyanya, iyo inobatsira zvikuru kuchengetedzwa kwekuchengetedzwa kwemunhu.Iyi nzira yakanakira mukuvaka, yakaderera mumutengo uye

zvinoshamisa mukuita, izvo zvichafarirwa uye kushandiswa.
