Chii chinobatisa mheni?Chii chinonzi surge protector?Vagadziri vemagetsi vanga vachiita indasitiri yemagetsi

kwemakore akawanda anofanira kuziva izvi chaizvo.Asi kana zvasvika pamusiyano pakati pezvibatiso zvemheni nekuvhiya

vadziviriri, vazhinji vashandi vemagetsi vangave vasingakwanisi kuvaudza kwekanguva, uye mamwe magetsi ekutanga ari kunyange

more confused.Isu tese tinoziva kuti zvibatiso zvemheni zvinoshandiswa kuchengetedza midziyo yemagetsi kubva kune yakakwira inopfuura overvoltage

njodzi panguva yekurova kwemheni, uye kudzikisira nguva yemahara uye kazhinji kudzikisira iyo freewheeling amplitude.Mheni

ma arresters dzimwe nguva anonziwo overvoltage protectors uye overvoltage limiters.

Mudziviriri wekuvhiya, anozivikanwawo seanodzivirira mheni, chishandiso chemagetsi chinopa kuchengetedza kuchengetedza

zvakasiyana-siyana zvemagetsi zvemagetsi, zviridzwa, uye mitsara yekukurukurirana.Kana peak ikozvino kana voltage inongoerekana yaitika

mumagetsi emagetsi kana mutsara wekutaurirana nekuda kwekupindira kwekunze, inogona kuitisa shunt munguva pfupi zvikuru

kudzivirira kukuvadzwa kwekuwedzera kune zvimwe midziyo iri mudunhu.Saka, ndeupi musiyano uripo pakati pekusunga mheni nekuvhiya

mudziviriri?Pazasi isu tichaenzanisa misiyano mikuru mishanu pakati pevanosunga mheni uye vadziviriri vekuvhiya, kuitira kuti iwe

inogona kunyatsonzwisisa mabasa anoenderana emheni anosunga uye kudzivirira kwekuvhiya.Mushure mekuverenga chinyorwa ichi,

Ndinovimba ichapa vashandi vemagetsi kunzwisisa kwakadzama kwevanosunga mheni uye vadziviriri vekuvhiya.

01 Basa rekuvhiya vadziviriri uye vanosunga mheni

1. Surge mudziviriri: Surge mudziviriri anonziwo surge protector, yakaderera-voltage magetsi inopa mheni inodzivirira, mheni.

mudziviriri, SPD, etc. Chigadzirwa chemagetsi chinopa kuchengetedzwa kwemhando dzakasiyana dzemidziyo yemagetsi, zviridzwa,

uye mitsara yekukurukurirana.Icho chishandiso chemagetsi chinopa kuchengetedza kuchengetedza kwakasiyana midziyo yemagetsi,

zviridzwa, uye mitsara yekukurukurirana.Apo peak current kana voltage inongoerekana yaitika munharaunda yemagetsi kana

mutsara wekutaurirana nekuda kwekupindira kwekunze, muchengeti wekuvhiya anogona kuitisa uye kuvharira ikozvino munguva pfupi pfupi,

nokudaro kudzivirira kuvhiya kubva pakukuvadza mimwe michina iri mudunhu.

Pamusoro pekushandiswa mumunda wemagetsi, vadziviriri vekuvhiya vanodiwawo mune mamwe minda.Semudziyo wekudzivirira, ivo

ive nechokwadi chekuti michina inodzikisira kukanganisa kwekuvhiya panguva yekubatanidza maitiro.

2. Mheni inosunga: Mheni inosunga chinhu chekudzivirira mheni chinoshandiswa kuchengetedza midziyo yemagetsi kubva kune njodzi.

yeakakwira-inopfuudza overvoltage panguva yekurova kwemheni, uye kudzikisira iyo freewheeling nguva uye kudzikisira iyo freewheeling amplitude.

Iyo mheni inosunga dzimwe nguva inonziwo over-voltage arrester.

Chibatiso chemheni chishandiso chemagetsi chinogona kuburitsa mheni kana overvoltage simba panguva yekushanda kwesimba system,

chengetedza midziyo yemagetsi kubva pakukurumidza overvoltage njodzi, uye cheka freewheeling kudzivirira system grounding

short circuit.Mudziyo wakabatana pakati pe conductor nepasi kudzivirira kurova kwemheni, kazhinji inofambirana ne

midziyo yakadzivirirwa.Zvibatiso zvemheni zvinogona kudzivirira zvinobudirira midziyo yemagetsi.Pane imwe nguva abnormal voltage yaitika, musungwa

ichaita uye ichaita basa rekudzivirira.Kana kukosha kwevoltage kuri kwakajairika, musungwa anokurumidza kudzokera kune yake yekutanga kuti ave nechokwadi

iyo yakajairika magetsi emagetsi system.

Zvibatiso zvemheni zvinogona kushandiswa kwete chete kudzivirira kubva kumhepo yakakwira voltages, asiwo kubva pakushanda kwakakwira voltages.

Kana paine kutinhira, high voltage ichaitika nekuda kwemheni nekutinhira, uye midziyo yemagetsi inogona kunge iri munjodzi.

Panguva ino, inosunga mheni ichashanda kuchengetedza midziyo yemagetsi kubva pakuparara.Chikuru uye chakakosha

basa rekusunga mheni kudzikamisa overvoltage kudzivirira midziyo yemagetsi.

Chibatiso chemheni mudziyo unobvumira kuti mheni ipinde muvhu uye inodzivirira kugadzirwa kwemagetsi

moto muzhinji.Idzo mhando huru dzinosanganisira chubhu-mhando yezvibatiso, mavharuvhu-mhando yekuvhara, uye zinc oxide zvinosunga.Misimboti huru yekushanda

yemhando yega yega yekusunga mheni yakasiyana, asi yavo yekushanda yakangofanana, inova kuchengetedza midziyo yemagetsi kubva mukukuvadzwa.

02 Musiyano uripo pakati pezvibatiso zvemheni nevadziviriri vekuvhiya

1. Inoshanda voltage mazinga akasiyana

Mheni inosunga: Vanosunga mheni vane mazinga akawanda emagetsi, kubva pa 0.38KV low voltage kusvika 500KV Ultra-high voltage;

Surge mudziviriri: Surge mudziviriri ane yakaderera-voltage zvigadzirwa zvine akawanda voltage mazinga anotangira kubva kuAC 1000V uye DC 1500V.

2. Zvirongwa zvakaiswa zvakasiyana

Mheni inosunga: inowanzoiswa pane yekutanga system kudzivirira kupindira kwakananga kwemafungu emheni;

Surge mudziviriri: Yakaiswa pane yechipiri system, iri chiyero chekuwedzera mushure mekunge musungwa abvisa kupindira kwakananga.

yemafungu emheni, kana kuti musungwa paanotadza kubvisa masaisai emheni zvachose.

3. Nzvimbo yekuisa yakasiyana

Mheni inosunga: Inowanzo kuisirwa kune yakakwira-voltage cabinet pamberi pe transformer (inowanzoiswa mudunhu rinouya

kana dunhu rinobuda repamusoro-voltage kugovera kabati, kureva, pamberi pe transformer);

Surge mudziviriri: SPD yakaiswa mune yakaderera-voltage yekugovera kabhineti mushure meiyo transformer (inowanzo kuisirwa pakupinza kweiyo.

low-voltage distribution cabinet, kureva, kubuda kwe transformer).

4. Chitarisiko chakasiyana uye ukuru

Mheni inosunga: Nekuti yakabatana kune yemagetsi primary system, inofanirwa kunge iine yakakwana yekunze insulation performance

uye hukuru hwakakura hwekutaridzika;

Surge mudziviriri: Nekuti yakabatana kune yakaderera-voltage system, inogona kuve idiki kwazvo.

5. Nzira dzakasiyana dzekudzika pasi

Mheni inosunga: kazhinji nzira yekumisa yakananga;

Surge mudziviriri: SPD yakabatana kune PE mutsara.
