Mwenje yemumugwagwa yezuva inoda dziviriro yekuwedzera yemheni here?

Munguva yezhizha apo mheni inowanikwa kakawanda, sechishandiso chekunze, mwenje yemumugwagwa yezuva inofanira kuwedzera mimwe michina yekudzivirira mheni here?Fekitori yemwenje yemugwagwa Tianxianganotenda kuti nzira yakanaka yekudzika midzi yemidziyo inogona kuita basa rakati mukudzivirira mheni.

Nzira dzekudzivirira mheni pakuisa mwenje yemumugwagwa yezuva

Kusarudza mhando dzakasiyana dzemidziyo yekudzika pasi ndiyo nhanho yekutanga yekudzivirira mheni yemagetsi emumugwagwa ezuva. Midziyo inowanzo shandiswa yekudzika pasi inosanganisira kudzika kwesimbi, kudzika kwegridi yemagetsi, uye kudzika kwegridi yevhu. Matanho chaiwo ekushandisa ndeaya anotevera:

1. Nzira yesimbi yekudzika pasi

Chera gomba rakadzika 0.5m pasi pechigadziko chemwenje wezuva, isa simbi yakareba 2m, wobva wabatanidza pasi pechiedza chezuva nesimbi, wozozadza gomba racho.

2. Nzira yekudzika grid yemagetsi

Batanidza waya dzemwenje wezuva padanda remagetsi riri pedyo kuti ubatanidze denderedzwa remwenje wezuva pagrid yepasi.

3. Nzira yekudzika pasi kwegridi yepasi

Chera gomba rakadzika mita imwe pasi pechiedza chemumugwagwa chezuva, shandisa tambo yakaita serin'i kubatanidza chiedza chemumugwagwa chezuva kuburikidza nesimbi negridi yesimbi pasi pevhu, wobva wazadza gomba racho nekongiri.

Kudzivirira mheni pakuisa mwenje yezuva mumigwagwa

1. Chishandiso chekuisa pasi chinofanira kunge chakabatana zvakanaka nechiedza chemumugwagwa chezuva.

2. Sarudza kudzika kwakakodzera kwevhu. Harifanirwe kunge rakadzika zvakanyanya, sezvo rinogona kuwedzera kusimba kwevhu; harifanirwe kunge rakadzika zvakanyanya, sezvo rinogona kukonzera kuti ivhu rive rakanyorova zvakanyanya, zvichideredza kusimba kwevhu uye zvichikanganisa hurongwa hwevhu hwese.

3. Gara uchitarisa mitsetse yekudzika pasi uye kuramba kwepasi kuti uve nechokwadi chekuti system yekudzika pasi yakasimba.

Marambi emumugwagwa ezuva eTianxiangdzose dzakashongedzwa nemakeji ekudzika pasi, ayo akagadzirwa nesimbi uye atove nebasa rakati rekudzivirira mheni.

Chechipiri, mheni inowanzo rova ​​zvivakwa zvirefu kana masimbi, pane kurwisa chero chinhu chisina kurongeka. Pamusoro pezvose, zvinhu zvemuviri zvinoganhurira musimboti wekugadzirwa kwayo. Mapaneru edu ezuva haana kupinza uye haana kureba zvakanyanya, saka mukana wekurohwa nemheni wakaderera.

Chechitatu, tinogona kutaura nezvezvinhu zvine simba zvekutsvagisa mheni. Heino chirevo: “Zvichienderana nenhamba, vanhu vanopfuura 4,000 vanorohwa nemheni pasi rose gore rega rega. Kana vanhu vari pasi rose vari mabhiriyoni manomwe, avhareji yemukana wekuti munhu mumwe nemumwe arohwe nemheni ingangoita mumwe chete pamamiriyoni 1.75. Sekureva kweFederal Emergency Management Agency yeUnited States, avhareji yemukana wekuti muAmerica arohwe nemheni ingangoita mumwe pamazana matanhatu.” Mikana yekuti rimwe chete pamazana chiuru emwenje yemumugwagwa inorohwa nemheni gore rega rega i1,000 * 1/600,000 = 1.6‰, zvinoreva kuti zvaizotora makore 2,500 kuti rimwe chete rirohwe pamazana chiuru.

Pane chimwe chikonzero chekuwedzera. Sei magetsi mazhinji muguta aine matanho ekudzivirira mheni? Imhaka yekuti magetsi eguta akabatana panguva imwe chete uye panguva imwe chete, uye kana rambi rimwe chete rikarohwa nemheni, rinogona kukuvadza marambi akawanda ari pedyo. Zvisinei, marambi emumugwagwa ezuva haafanire kubatanidzwa uye haana marambi akabatana panguva imwe chete.

Mukupedzisa, tinotenda kuti mwenje yemumugwagwa yezuva haidi mamwe matanho ekudzivirira mheni. Heano mamwe ezviitiko zvedu:

1. Kana kukwirira kwechiedza chemumugwagwa chezuva kwakaderera uye paine zvivakwa zvakareba kana miti iri pedyo kuti ikwezve mheni, mukana wekurohwa zvakananga nemheni wakaderera.

2. Mapaneru ezuva emazuva ano haasi maconductor akapinza uye anowanzo shandisa mafuremu asiri esimbi, zvichiita kuti asanyanya kukwezva mheni.

3. Munzvimbo dzine mheni yakawanda, sisitimu yakakwana yekudzivirira mheni (grounding + SPD + lightning rod) inofanira kuiswa.
