Magetsi anofamba kusvika papi mumvura?

Mvura inowanzonzi yakanaka conductor yemagetsi nekuti kana mukati memvura muine mhepo munhu akaibata anogona kubatwa nemagetsi.

Pane zvinhu zviviri zvekucherechedza zvingave zvakakosha. Chimwe chazvo imhando yemvura kana kuwanda kwemunyu uye mamwe maminerari, uye yechipiri ndiyo chinhambwe kubva panzvimbo yekubata magetsi. Ichi chinyorwa chinotsanangura zvose asi chinotarisa chechipiri chekuongorora kuti magetsi anofamba sei mumvura.

Tinogona kusiyanisa nzvimbo ina dzakatenderedza poindi yemagetsi mumvura (njodzi huru, njodzi, njodzi iri pakati nepakati, yakachengeteka). Zvakadaro, chinhambwe chaicho kubva kunobva nzvimbo yakaoma kuziva. Zvinotsamira pazvinhu zvakati wandei, zvinosanganisira kushushikana/kusimba, kugovera, kudzika, salinity, tembiricha, topography, uye nzira yekushomeka kushomeka.

Hukoshi hwechinhambwe chekuchengetedza mumvura zvinoenderana nereshiyo yekukanganisa ikozvino kune yakanyanya kuchengeteka muviri ikozvino (10 mA yeAC, 40 mA yeDC):

• Kana iyo AC kukanganisa ikozvino iri 40A, nzvimbo yekuchengetedza mumvura yegungwa ichave 0.18m.
• Kana tambo yemagetsi iri pasi (pavhu rakaoma), unofanira kugara 33 feet (10 metres) kure, inova kureba kwebhazi. Mumvura, chinhambwe ichi chaizova chikuru zvikuru.
• Kana toaster ikawira mumvura, iwe unofanirwa kunge uri mukati me360 tsoka (110 metres) kubva patsime remagetsi.

Ndichaenda mune zvakadzama pazasi.

Sei zvakakosha kuziva

Zvakakosha kuziva kuti magetsi anofamba sei mumvura nekuti kana paine magetsi kana ari pasi pemvura aripo, anenge asangana nemvura ari panjodzi yekubatwa nemagetsi.

Zvingave zvinobatsira kuziva kuti ndechipi chinhambwe chakachengeteka kudzivirira njodzi iyi. Apo njodzi iyi inogona kunge iripo mumamiriro emvura, zvakakosha zvikuru kuva neruzivo urwu.

Chimwe chikonzero chokuziva kuti simba remagetsi rinogona kufamba kureba sei mumvura kuredza kwemagetsi, uko magetsi anopfuudzwa nemaune mumvura kuti abate hove.

Mhando yemvura

Mvura yakachena insulator yakanaka. Dai pakange pasina munyu kana zvimwe zvicherwa, njodzi yekuvhunduka kwemagetsi yaizova shoma nekuti magetsi aisakwanisa kufamba kure mukati memvura yakachena. Mukuita, zvisinei, kunyange mvura inoita seyakajeka inogona kunge iine mamwe ma ionic makomisheni. Ndiwo maion aya anogona kuitisa magetsi.

Kuwana mvura yakachena yaisaita kuti magetsi apinde hakusi nyore. Kunyange mvura yakasvibiswa yakanyungudutswa kubva mumvura yakasvibiswa uye yakasvibiswa yakagadzirirwa mumarabhoritari esainzi inogona kuva nemamwe maion. Izvi zvinodaro nekuti mvura inonyungudutsa yakanakisa yezvicherwa zvakasiyana, makemikari, uye zvimwe zvinhu.

Mvura yauri kufunga kuti magetsi anoenda kureba ingangove isina kuchena. Mvura yemupombi yakajairika, mvura yemurwizi, mvura yegungwa, nezvimwe hazvizove zvakachena. Kusiyana nekufungidzira kana kuoma-kuwana-mvura yakachena, mvura yemunyu inoitisa zvirinani magetsi nekuda kwemunyu (NaCl) wemukati. Izvi zvinoita kuti ayoni afambe, sezvinoita maerekitironi anoyerera kana achifambisa magetsi.

Distance kubva pakuonana

Sezvaungatarisira, kana iwe uri pedyo kusvika pakubata mumvura ine tsime remagetsi emagetsi, ichava nengozi zvikuru, uye kure kure, simba remhepo richava shoma. Ikozvino inogona kunge yakadzikira zvekuti irege kuva nengozi pane imwe chinhambwe.

Kureba kubva panzvimbo yekubatana chinhu chakakosha. Nemamwe mashoko, tinofanira kuziva kuti magetsi anofamba sei mumvura asati apera simba kuti achengetedzeke. Izvi zvinogona kukosha sekuziva kuti magetsi anosvika kureba sei mumvura yese kusvika yazvino kana voltage isingaite, pedyo kana kuenzana ne zero.

Tinogona kusiyanisa nzvimbo dzinotevera dzakatenderedza nzvimbo yekutanga, kubva padyo kusvika kunzvimbo iri kure.

• High ngozi zone -Kusangana nemvura mukati menzvimbo iyi kunogona kuuraya.
• Dangerous zone -Kusangana nemvura mukati menzvimbo iyi kunogona kukuvadza zvakanyanya.
• Moderate Risk Zone - Mukati menzvimbo iyi, mune manzwiro ekuti kune ikozvino mumvura, asi njodzi dziri pakati kana pasi.
• Safe Zone - Mukati meiyi zone, iwe uri kure zvakakwana kubva kune simba sosi zvekuti magetsi anogona kuve nengozi.

Kunyangwe takaona nzvimbo idzi, kuona kureba chaiko pakati pawo hakusi nyore. Pane zvinhu zvakati wandei zvinobatanidzwa pano, saka tinogona kungozvifungidzira.

Chenjera! Paunenge uchiziva kuti panobva magetsi mumvura, unofanira kuedza kugara kure nayo sezvinobvira uye, kana uchikwanisa, dzima magetsi.

Njodzi uye kuchengeteka kureba kuongorora

Tinogona kuongorora njodzi uye chengetedzo chinhambwe zvichibva pane zvinotevera zvipfumbamwe zvakakosha zvinhu:

• Tension kana kusimba -Iyo yakakwira voltage (kana kusimba kwemheni), inowedzera njodzi yekuvhunduka kwemagetsi.
• Distribute -Magetsi anoparadza kana kuparadzira mativi ese mumvura, kunyanya padyo nepamusoro pedenga.
• kudzika “Magetsi haapinde zvakadzika mumvura. Kunyange mheni inongofamba kusvika pakadzika dzingangoita mamita makumi maviri isati yaparara.
• munyu - Iyo yakawanda munyu mumvura, iyo yakawanda uye yakafara ichave inoiswa magetsi nyore nyore. Mafashamo emvura yegungwa ane salinity yakakwira uye yakaderera resistivity (kazhinji ~ 22 ohmcm zvichienzaniswa ne420k ohmcm yemvura yemvura).
• Температура Kana mvura ichidziya, ndiko kukurumidza kufamba kwemamorekuru ayo. Nokudaro, magetsi emagetsi achavawo nyore kuparadzira mumvura inodziya.
• Topography - Mamiriro enzvimbo yenzvimbo anogonawo basa.
• Nzira -Njodzi yekuvhunduka kwemagetsi mumvura yakakwira kana muviri wako ukava nzira yekusagadzikana kuti iyo yazvino iyerera. Iwe wakangochengeteka chete chero paine dzimwe nzira dzakaderera dzekupikisa dzakakupoteredza.
• touch point -Nzvimbo dzakasiyana dzemuviri dzine kuramba dzakasiyana. Semuenzaniso, ruoko runowanzo kuve neresistivity yakaderera (~ 160 ohmcm) kupfuura torso (~ 415 ohmcm).
• Bvisa mudziyo -Njodzi yakakura kana pasina mudziyo wekubvisa kana paine imwe uye nguva yayo yekuita inodarika makumi maviri ms.

Kuverengera kwenzvimbo yekuchengetedza

Kufungidzira kwechinhambwe chakachengeteka chinogona kuitwa zvichibva pamakodhi ekudzidzira kushandiswa kwakachengeteka kwemagetsi ari pasi pemvura uye tsvakiridzo muinjiniya yemagetsi epasi pemvura.

Pasina kusunungurwa kwakakodzera kudzora AC ikozvino, kana muviri wazvino usingapfuuri 10 mA uye muviri wekutsvaga kuramba uri 750 ohms, ipapo iyo yakawanda yakachengeteka yakachengeteka ndeye 6-7.5V. [1] Hukoshi hwechinhambwe chekuchengetedza mumvura zvinoenderana nereshiyo yekukanganisa ikozvino kune yakanyanya kuchengeteka muviri ikozvino (10 mA yeAC, 40 mA yeDC):

• Kana iyo AC kukanganisa ikozvino iri 40A, nzvimbo yekuchengetedza mumvura yegungwa ichave 0.18m.
• Kana tambo yemagetsi iri pasi (pavhu rakaoma), unofanira kugara 33 feet (10 metres) kure, inova kureba kwebhazi. [2] Mumvura, chinhambwe ichi chinenge chakareba.
• Kana toaster ikawira mumvura, iwe unofanirwa kunge uri mukati me360 tsoka (110 metres) kubva patsime remagetsi. [3]

Ungaziva sei kana mvura yaiswa magetsi?

Kunze kwemubvunzo wekuti magetsi anofamba sei mumvura, mumwe mubvunzo wakakosha wakabatana ungave kuziva nzira yekuziva kana mvura yaiswa magetsi.

cool chokwadi: Sharks inogona kuona zvishoma se 1 volt mutsauko mamaira mashoma kubva kunobva magetsi.

Asi tingaziva sei kana mvura iri kuyerera zvachose?

Kana mvura iine magetsi akawanda, unogona kufunga kuti uchaona pfarivari nemabhaudhi mairi. Asi handizvo. Sezvineiwo, hapana chauchaona, saka haugone kutaura nekuona mvura chete. Pasina chishandiso chazvino chekuyedza, nzira chete yekuziva ndeyekunzwa nayo, izvo zvinogona kuve nengozi.

Imwe nzira chete yekuziva chokwadi ndeyekuyedza mvura yezvino.

Kana iwe uine dziva remvura kumba, unogona kushandisa mudziyo wekuvhunduka usati wapinda mairi. Chigadzirwa chacho chinovhenekera chitsvuku kana chaona magetsi mumvura. Zvisinei, munguva yenjodzi, zviri nani kugara kure nekwaunobva sezvinobvira.

Tarisa zvimwe zvezvinyorwa zvedu pazasi.

• Ko magetsi eusiku anoshandisa magetsi akawanda
• Magetsi anogona kupfuura nemuhuni here
• Nitrogen inofambisa magetsi
