Mheni kuchengetedzwa maitiro: magadzirirwo kugadzwa

Nemheni, iro rikawira pasi STRUCTURAL zvinhu zvezvivako, achiperekedzwa nokugura remagetsi simba. Izviwo, isakarurama zvarinoita kushanda magetsi. Usanyanya kuvadza waya conductors uye kuderedza ndingangokuvara kurova chinhu kupomera simba kunoita magadzirirwo semheni kudzivirira enyika.

mamiriro

Mheni Rod - pusa unodzivirira chiyero kunovimbisa akachengeteka mukushanda zvivako, anoramba utano uye upenyu yevashandi, varimi panguva kunorira dzinongoitika dzoga. Mheni kudzivirira hurongwa ine zvinotevera huru zvinhu:

• Mugamuchiri buditsa.
• A nemuteresi.
• The grounding redunhu.

mhando mheni Protection

Zvino govera kuputika uye pusa mheni kuchengetedzwa hurongwa. Traditional - pusa musimboti zvinosanganisira zvinoyerera mugamuchiri maatomu akafanana uye nomuteresi grounding. Nheyo kushanda zvakadaro kwava nyore. Mheni tsvimbo anotora mheni amurove, uye ipapo anotuma nayo pasi kuburikidza conductive nomuteresi nzira. Pakupedzisira, zvinoyerera chisisimo muvhu.

Uyewo, kushingaira mheni kudzivirira hurongwa anoshanda panheyo mhepo ionization. Nokuda izvi uye zvinoyerera kuvhura kunoitika. Active mheni kudzivirira hurongwa inoumbwa chete zvinhu sezvo pusa. Zvisinei, avo siyana iri yakakura uye rinosvika anenge 100 metres. Pano, kudzivirirwa harisi chete chinhu, pamusoro izvo hwavapo pezvokuvamba ezvinhu, asi zvivako pedyo.

Active mheni chinodzivirira zvikuru tibudirire. Hazvishamisi kuti shoko rakadaro nezvechisarudzo Zvinosarudzwa vanoshandisa dzakawanda dzakabudirira. Zvisinei, mari sarudzo akadaro yepamusoro zvikuru.

Embodiments pakuyerera vagamuchiri

Mureza polniepriemnik chinhu kwakajairika chesimbi mbambo kuti akatasva nenzira wehunyambiri nechinzvimbo pamusoro pedenga mamiriro. Zvinokosha kugadzirisa chinhu chepamusoro rakazaruka pfungwa padenga. Kana imba ane kunzwisisa denga design, maererano nani kuchengeteka, Zvinokurudzirwa kugadzwa wandei pakuyerera vagamuchiri.

Patsanura chaiwo embodiments mheni tsvimbo, izvo zvakasiyana maererano musimboti:

• Chamboko kudzivirirwa.
• Metal waya.
• Mheni kuchengetedzwa pajira riya.

chamboko kudzivirirwa

Kana imba ine simbi denga, umo nyaya zvakarurama mhinduro anotarira kugadzwa Pin mheni kudzivirira hurongwa. Kubhururuka pamusoro zvinoyerera mugamuchiri muchimiro mureza simbi tsvimbo vakatakurwa imwe yakakwirira. Last chokuita pasi kuburikidza vateresi.

Mbambo kudzivirirwa anogona kupiwa muchimiro muchikamu resimbi tsvimbo ose zvinenge 8 mm kana zviuno nesimbi chidimbu 25 pamwe parameters X 4. Kureba zvinoyerera kugamuchira nhengo inofanira kuva yokuti kuguma mvura yaro yakaita rusvingo pamusoro kukwira pamusoro chinhu pfungwa vanenge 2 mamita.

Kukwirira mbambo nzvimbo zvakananga kunokanganisa mano kwemheni kudzivirirwa uye grounding hurongwa ichengete pamusoro kokuyerera kuparadzwa nzvimbo huru. Area, iyo inogona kudzivirira interdigital mheni kondakita Inonzi denderedzwa rine nharaunda akafanana kumusoro wetsvimbo.

tambo kudzivirirwa

In pamberi padenga akafukidzwa nemakadhibhokisi pabhodhi, mheni mugamuchiri rinoitwa muchimiro simbi muhuro. Last muedzo achitevedza akatevedzana padenga. Kukwirira kwayo nzvimbo anofanira kanenge 0.5 metres pachiso.

Kana zvakakodzera kusika chakavimbika kupfuura kudzivirira waya makakatanwa akashandisa esimbi zvitsigiso, izvo kure zvinoyerera receiver. Nzira iyi ndiyo zvinoshandawo kuti zvakagadzirwa nezvinhu emapuranga matenga uye matenga ari muchimiro zvedongo usina kukonekita.

yepasi kudzivirira

Izvi mhinduro anoita sendarama zvakaoma dzika. Kazhinji kushandiswa pamatenga akafukidzwa usina kukonekita. Mugamuchiri kukangamwirwa iyi ndiyo waya pajira riya pamusoro pedenga mamiriro. Muchinjikwa-Chikamu nemagetsi conductors iyi nyaya zvinofanira kanenge 6 neMM, uye kukwirira kwenzwi kwamakamuri - murayiro 6 X 6 m.

The ezvinhu vaiona kwakabatana kuti muteresi uye pasi chinhu nokuda Welding. In kusavapo mukana wakadaro anobvumirwa kushandisa sikuruu fasteners.

Kubhururuka of vateresi rinoitwa kushandisa kumativi simbi waya. Kugadzira navo kurutivi pasi pamusoro pamasvingo uye padenga chivakwa, kugadzirira nemagetsi conductors chaizvo mumabhuraketi.

Route nokuti rikaisa nomuteresi zvinhu anosarudzwa kuitira kuti magetsi achitungamirira zvinhu havasi uchikurukura madhoo, mawindo, berere, simbi garaji madhoo, dzimwe mazano, izvo zvingaita kushamwaridzana nevanhu mukufamba kushanda.

Kana chivako unotora wayo maumbirwo zvakawanda combustible zvinhu (polystyrene, huni, mapurasitiki), kuti conductors ari muteresi inofanira akaiswa chinhambwe kubva hukawanika vanenge 15-20 cm. Kutungamirirwa urongwa mheni dziviriro hurongwa kudzivisa panowanikwa moto iri simba, refu mabhanan'ana.

Muchiitiko chino, izvozvo zvinogona hwavapo womukati mheni dziviriro hurongwa, unosanganisira kugadzwa dzinokosha fuses anokwanisa kudzivirira magetsi pakaitika. Mari idzi inoiswa pedyo napedyo kusvika kupinza pfungwa nesimba wire kupinda chinhu.

The nemuteresi

Mutauriri fanira chaikosha mheni kudzivirira enyika. Yakagadzirwa uchatamisa mutariri kuti gandiwa zvevhu.

The nemuteresi chinhu esimbi waya iri kanenge 6 mm paukobvu, iyo zvakabatana zvinoyerera receiver. The zvose zviri zviviri zvinhu zvinoita kuti kubhadhara mutoro kune 200,000 amperes. Anokosha Mamiriro STRUCTURAL zvinoriumba Nekubatanidza mabasa aya kuita zvikuru yakavimbika nomoto, iyo anobvisa mukana atsamwira kuti kubatana uye nokusazvibata nemhepo, vari kuwa chando akaturikidzana.

The nemuteresi iri akatura pamusoro pamasvingo chinhu kubva kumusoro, fastening waya zvinodyiwa. Kumigumo simbi waya inoendeswa grounding redunhu. Kana hurongwa mheni kudzivirira zvivako inosanganisira kugadzwa vakawanda kupomera conductive okunze, vari papi pane chinhambwe 20-25 metres kunze panguva mukuru zvaibvira daro pamikova uye mahwindo.

Maererano Safety, Current taps hazvitenderwi zvikuru hwakakungwa. The kubvuma zvikanganiso zvakadaro kunowedzera ndingangokuvara panowanikwa chinopa kukangamwirwa nyaya kukundwa chinhu mheni. Izviwo, kungaita kuti kuzvimba chacho.

Panguva kuisa kwemheni unodzivirira mugadziriro, zviri chinodiwa kuti nomuteresi sezvo pfupi sezvinobvira. Panguva imwe cheteyo, Zvinokurudzirwa yokugadza pedyo cusps, kumicheto pakati Gables, vachinzwa mahwindo.

grounding

grounding mudziyo akagadzirirwa nechokwadi chinobudirira kubviswa zvinoyerera muvhu. Rinomirira electrodes akawanda hwakabatana pamwe chete, Akarovera muvhu.

Pakatanga nzvimbo, maererano nemirau, pakutanga nezvamunobvumirana vose magetsi chokuita nemambure anofanira inopiwa. Kana kwete, gadzirira ichocho hachisi kuoma zvakadaro. To ichi chinobviswa simbi kana mhangura kondakita-chikamu vomuchinjikwa 50-80 mm. Akachera mugoronga urefu 3 M uye kudzika kwete asingasviki 0,8 m. On akatarisana kumativi mukudzokera vari nemhepo tsvimbo, ayo zvakabatanidzwa ne Welding simbi kwepuranga rakachinjika. To kunoguma maumbirwo akabatanidzwa nemuteresi. Pamugumo Welding nzvimbo akasvibiswa ibvi, dzakatsigira grounding mamiriro kuzadza pasi mugoronga.

Verification mheni kudzivirira nehurongwa

buditsa nzira yokubudisa Hurongwa bvunzo kunosanganisirawo kutarisana vaongo- pamusoro STRUCTURAL okunze uye kuyera nemishonga parameters. Externally akapupurirawo rakavimbika magetsi kubatana pakati mhepo chinouraya, mumwe nomuteresi uye pasi. weld All tapping pamwe nenyundo.

Kuyerwa nomumwe zviratidzi nemishonga grounding mheni uye bolting kunosanganisira midziyo inokosha vakanyorwa maererano nemitemo.

Somugumisiro,

Sezvaunogona kuona, pane nzira dzakawanda kuti mheni kudzivirira chivako. Avo kana dzimwe mhinduro vakasarudzwa zvichienderana Latitude of bhajeti, chimiro zvakasikwa, kuitira pamwero vakachengeteka kunodiwa.

Panguva ino, kukura simba muzvirongwa hakuiti kusika mheni pakatanga chinhu. Kanenge, ayo pamberi haisi kuzvireva. Naizvozvo chisarudzo musi kana urongwa mamiriro kudzivirirwa rurege vakarohwa nemheni iri nokugamuchirwa muridzi nomumwe maererano pachavo zvinhu.
