Umhlaba zothintelo: eletropriborov zokhuseleko

indawo yokhuselo kucingwa ukuba ngokukhethekileyo kwenziwa uqhagamshelwano lombane emhlabeni of kuphila iinxalenye yesinyithi, leyo, ngenxa yokuvalwa izindlu fowuni zibe ubomi. Oku kwenzeka uqhagamshelwano lombane random hayi kuphila iinxalenye ebuntsimbi le mveliso kunye iziqalelo conductive, le ombane naye yenzeke, umzekelo, nemibane.

Nomhlaba olukhuselayo ishenxisa ingozi ugesi xa uchukumisa iindawo eziphilayo omzimba yesinyithi okanye izixhobo leyo, ngenxa earthing yabonakala amandla.

Kufuneka ibe ahluka yokusebenza earthing yokhuselo, nto leyo yenzelwe ukusebenza eyiyo ufakelo zombane, kwakunye ukusuka emhlabeni ukuya awukhusele njengombane. Ngokusebenza kungabandakanya oyicinezelayo nemisinga cala yomvelisi jiko le transformer amandla kunye nezinye izixhobo.

Kuba isisekelo yesixhobo ofuna ukusebenzisa izixhobo zendalo kunye nezinto: metal kunye nemibhobho yamanzi ezingenawo anti-umhlwa ukutyabeka, ngaphandle imibhobho kunye igesi okanye ulwelo edubulayo okanye ezinokutsha. Ifanelekile isisekelo elikhokelayo intambo sheathing, iivelufa kunye izinto ezibengezelayo izakhiwo ufakelo lwesamente okanye izakhiwo. wazi ukuba lo mhlaba kufuneka abe ngokunxulumene nomhlaba nje. Kwakhona izikhonkwane zentsimbi ofanelekileyo okanye istili. Kodwa abaqhubi aluminium ebalelelwe lilanga kunye cable sheathing Akuvunyelwe ukuyisebenzisa le nto.

Xa engekho electrode zomhlaba zendalo okanye ukuba babe ukumelana eliphezulu ingasetyenziswa ukuba ngumntu, kunye adala isiseko olukhuselayo. Bona ezenziwe ngentsimbi lembombo ziqwempu 5h5h0,5 ubude leemitha 2-3, ubukhulu efanayo cm lemibhobho zentsimbi enobubanzi ka-5 cm ngesinyithi ziqwempu setyhula (ubude 5 m, ububanzi 12.0 - 14,0 mm). iindawo Used (electrode) kufuneka ukuxakeka emhlabeni kumgama omnye komnye kweemitha 3-5, zonke izinto kufuneka adityaniswe phakathi estrip sentsimbi, icandelo umnqamlezo mm 40x4.

Zephetshana ohlanganisa ibekwa ngaphakathi kothango lweenqwelo zokulwa ukuya kubunzulu eziimitha 0,70, umgama elifanayo ukusuka kumphezulu lo iziphelo engentla i electrode. Zonke izinto idityaniswe ukuwelda. Inani electrode libalwa, esekelwe resistivity komhlaba, ubungakanani electrode, ubunzulu ukuqanda kunye nezinye izinto.

isisekelo ombane yombane kukhuseleko amawaka B ukuze kuququzelelwa esebenzisa izakhiwo yenkcenkce sakhiwo (phambi uxhulumaniso ethembekileyo lweziqalelo wesiphaluka), wirings iityhubhu intsimbi, aluminiyam sheaths intambo, imibhobho ebuntsimbi (ngaphandle iinkqubo zokufudumeza, kunye amdaka umbhobho). neengcedevu metal, iibhokisi, nemiluko kunye busbars neziphaluka zero ucingo (umhlaba zokuzikhusela cala) nayo kusetyenziswa.

Njengoko ababhexeshi protective zero Akuvunyelwe ukusebenzisa intsimbi kunye oonokrwece ezingcakacileyo zikhokelela macingo neentambo. Air AC nyamalala ngokusebenzisa umqhubi cala, ezibekwe kwi isekela efanayo izinikezeli isigaba.

Nangona kunjalo, lo angaphinde ayisoloko ukuqinisekisa ukhuseleko oluyimfuneko ukuze abantu banxibelelane ngofakelo lombane. Kwezinye iimeko, kwiindawo kunye nengozi eyonyukileyo shwaka, kunye kwakhona ukusetyenziswa earthing okubakhusela okanye cima ikhompyutha ukhuseleko iyasetyenziswa. iingcingo zothintelo cala Akuvunyelwe isicelo ukuba angaphinde zonke izixhobo zombane, lusidla kwezinye imigca, njengoko unako uvalelwe yesondlo.

Ukuze izixhobo zokhuselo ziquka benza okuchasene beesekethe, isabela ukuvuza yangoku. Ukusetyenziswa kwezi zixhobo kwi ezindlini nga ukuphucula ukhuseleko lombane.
