Ndezvipi zvinotsanangurwa uye zvinodiwa zvekugadzirwa kwemagetsi?

Nzira dzekudzivirira dzekugadzirisa hurongwa hwemagetsi dzinosanganisira: inodzivirira ivhu, inodzivirira isina hukama kubatana, inodzokororwa pasi,

kushanda grounding, etc. Kubatana kwemagetsi kwakanaka pakati pechikamu chemidziyo yemagetsi uye pasi inonzi grounding.Iyo simbi

kondakita kana simbi conductor boka rinosangana zvakananga nevhu revhu rinonzi grounding body: the ground conductor: the metal conductor inobatanidza

kudzika chikamu chemidziyo yemagetsi kumutumbi wepasi kunonzi tambo yepasi;The grounding body and grounding wire ndizvo

pamwe chete zvinonzi zvigadziriso zvepasi.

Grounding pfungwa uye mhando

(1) Mheni kudzivirira pasi: kugadzika nechinangwa chekukurumidza kupinza mheni muvhu uye kudzivirira kukuvara kwemheni.

Kana mudziyo wekudzivirira mheni uchigovera giredhi yekugadzika neyakagadzika yekushanda kwemidziyo yeteregirafu, kuramba kwepasi.

ichazadzisa zvishoma zvinodiwa.

(2) AC kushanda pasi: simbi yekubatanidza pakati penzvimbo musimba remagetsi uye pasi zvakananga kana kuburikidza nemidziyo yakakosha.Kushanda

grounding rinonyanya kureva kudzika kwe transformer kwazvakarerekera kana kwazvakarerekera mutsetse (N line).N wire inofanira kunge iri copper core insulated waya.Ikoko

ndiwo ekubatsira equipotential terminals mukugovera magetsi, uye equipotential terminals anowanzo mu cabinet.Zvinofanira kucherechedzwa kuti

iyo terminal block haigone kuburitswa;Izvo hazvifanirwe kusanganiswa nemamwe masisitimu epasi, senge DC grounding, shielding grounding, anti-static

grounding, etc;Haikwanise kubatanidzwa ne PE line.

(3) Chengetedzo yekudzivirira pasi: kuchengetedzwa kwekuchengetedza pasi kugadzira simbi yakanaka yekubatanidza pakati pesimbi isina kubhadhariswa chikamu chemagetsi.

midziyo uye muviri wepasi.Midziyo yemagetsi muchivako uye zvimwe zvikamu zvesimbi padyo nemidziyo zvakabatanidzwa

PE mitsetse, asi inorambidzwa zvachose kubatanidza mitsara yePE neN mitsetse.

(4) DC grounding: Kuti ive nechokwadi chekurongeka uye kugadzikana kwega yega midziyo yemagetsi, yakagadzikana yereferensi inogona kupihwa mukuwedzera.

kune yakagadzikana magetsi.Iyo insulated mhangura yepakati waya ine nzvimbo yakakura yechikamu inogona kushandiswa semutungamiri, imwe magumo ayo akabatana zvakananga ne

referensi inogona, uye imwe magumo inoshandiswa kuDC kugadzika kwemidziyo yemagetsi.

(5) Anti static grounding: iyo ivhu kudzivirira kukanganiswa kwemagetsi akamira anogadzirwa munzvimbo yakaoma yekamuri yekombuta mukamuri.

Kuvaka zvine hungwaru kumidziyo yemagetsi inonzi anti-static grounding.

(6) Shielding grounding: kuitira kudzivirira kunze kwemagetsi kupindira, iyo yekudzivirira waya kana simbi pombi mukati uye kunze kwemagetsi.

midziyo yakavharirwa uye midziyo inoiswa pasi, iyo inonzi shielding grounding.

(7) Power grounding system: mumidziyo yemagetsi, kudzivirira kupindira kwemagetsi emhando dzakasiyana siyana kubva pakupinda kuburikidza neAC uye DC simba.

mitsara uye inokanganisa kushanda kwezviratidzo zvakaderera, AC uye DC mafirita akaiswa.Kudzika kwemasefa kunonzi power grounding.

Mabasa ekugadzirisa pasi akakamurwa kuva inodzivirira pasi, kushanda pasi uye anti-static grounding

(1) Magomba esimbi, kongiri, mapango, nezvimwe zvemidziyo yemagetsi zvinogona kuisirwa magetsi nekuda kwekukuvara kwekudzivirira.Kuti tidzivise mamiriro aya kubva

kuisa pangozi kuchengetedzeka kwemunhu uye kudzivirira tsaona dzekuvhundutsa kwemagetsi, magomba esimbi emidziyo yemagetsi akabatana nemudziyo wepasi.

kudzivirira pasi.Kana muviri wemunhu unobata midziyo yemagetsi negoko rakaiswa magetsi, kupikisa kwekubata kwepasi

muviri wakaderera zvakanyanya pane kuramba kwemuviri wemunhu, Mazhinji emazuva ano anopinda pasi kuburikidza nemuviri wepasi, uye chikamu chidiki chete chinoyerera kuburikidza.

muviri wemunhu, usingazoise upenyu hwevanhu mungozi.

(2) Iyo grounding yakaitwa kuti ive nechokwadi chekushanda kwakavimbika kwemidziyo yemagetsi pasi peyakajairika uye njodzi mamiriro anonzi kushanda

grounding.Semuyenzaniso, kudzika kwakananga uye kudzika kusina kunanga kwenzvimbo isina kwayakarerekera pamwe nekudzokororwa kudzokororwa kwe zero mutsara nemheni.

kudzivirira grounding zvose zviri kushanda grounding.Kuti uise mheni muvhu, batanidza nzvimbo yekugadzika yemheni

midziyo yekudzivirira (tsvimbo yemheni, nezvimwewo) pasi kuti ibvise kukuvadza kwemheni yakawandisa kumidziyo yemagetsi, zvivakwa zvemunhu,

inozivikanwawo sekuti overvoltage protection grounding.

(3) Kugadzikwa kwemafuta emafuta, matangi ekuchengetedza gasi, mapaipi, zvigadzirwa zvemagetsi, nezvimwe zvinonzi anti-static grounding kudzivirira kukanganisa.

Zvinodiwa pakuisa grounding mudziyo

(1) Waya yepasi inowanzoita 40mm × 4mm galvanized flat simbi.

(2) Muviri wepasi uchave wakabatiswa simbi pombi kana angle simbi.Iyo dhayamita yepombi yesimbi ndeye 50mm, iyo pombi rusvingo ukobvu haisi shoma

kupfuura 3.5mm, uye kureba i2-3 m.50mm yekona simbi × 50mm × 5 mm.

(3) Pamusoro pemuviri wepasi pane 0.5 ~ 0.8m kubva pasi kudzivirira kunyungudika ivhu.Huwandu hwemapombi esimbi kana makona simbi zvinoenderana

paivhu rekudzivirira kutenderedza muviri wepasi, kazhinji kwete pasi pemaviri, uye nzvimbo pakati peumwe neumwe i3 ~ 5m.

(4) Mufambo uri pakati pemutumbi wepasi nechivakwa uchave unopfuura 1.5m, uye chinhambwe chiri pakati pemutumbi wepasi nechivakwa.

yakazvimirira mheni tsvimbo yekumisa muviri inofanira kupfuura 3m.

(5) Lap welding ichashandiswa kubatanidza waya yekudzika uye muviri wepasi.

Nzira dzekuderedza kusagadzikana kwevhu

(1) Pamberi pekugadzwa kwechigadzirwa chepasi, resistative yevhu rakatenderedza muviri wepasi rinozonzwisiswa.Kana yakanyanya kuwanda,

matanho anodiwa achatorwa kuti ave nechokwadi chekuti pasi pekupikisa kukosha kwakakodzera.

(2) Shandura chimiro chevhu chakatenderedza mutumbi wepasi mukati me2 ~ 3m yevhu rakatenderedza muviri wepasi, uye wedzera zvinhu zviri

isingapindi mvura uye ine mvura yakanaka yekunyura, semarasha, coke cinder kana slag.Iyi nzira inogona kuderedza resistivity yevhu kusvika

yekutanga 15 ~ 110.

(3) Shandisa munyu uye marasha kuti uderedze kurwisa kwevhu.Shandisa munyu nemarasha kukanda muzvikamu.Iyo marasha uye yakanaka inosanganiswa mumucheka, pamusoro

10 ~ 15cm gobvu, uyezve 2 ~ 3cm yemunyu inoiswa, inokwana 5 ~ 8 zvidimbu.Mushure mekugadzira, tyaira mumutumbi wepasi.Iyi nzira inogona kuderedza

resistivity kune yekutanga 13 ~ 15.Nekudaro, munyu unorasika nemvura inoyerera nekufamba kwenguva, uye kazhinji zvinodikanwa kuizadza zvakare

kupfuura makore maviri.

(4) Ivhu rekudzivirira rinogona kuderedzwa kusvika ku40% nekushandisa kwenguva refu-inoita kemikari resistance reducer.The grounding resistance yemidziyo yemagetsi

ichaongororwa kamwe chete pagore muchirimo uye matsutso apo mvura inenge iri shoma kuti pave nechokwadi chokuti ivhu rakakodzera.Kazhinji, inokosha

zviridzwa (zvakadai seZC-8 grounding resistance tester) zvinoshandiswa pakuedza, uye nzira yeammeter voltmeter inogonawo kushandiswa pakuedza.

Zviri mukati mekuongorora kwepasi zvinosanganisira
