Kusiyana Pakati pa Surge Protector ndi Arrester

Oteteza ma Surge ndi omanga mphezi sizinthu zomwezo.

Ngakhale onsewa ali ndi ntchito yoletsa kuchulukirachulukira, makamaka kupewa kuphulika kwa mphezi, pali kusiyana kwakukulu pakugwiritsira ntchito.

1. Chomangira chimakhala ndi ma voltages angapo, kuyambira 0.38KV low voltage mpaka 500KV UHV, pomwe oteteza mawotchi nthawi zambiri amakhala ndi zinthu zochepa zamagetsi;

2. Womangayo amaikidwa pa dongosolo loyamba kuti asalowetse mwachindunji mafunde a mphezi.Chitetezo cha opaleshoni chimayikidwa kwambiri pa dongosolo lachiwiri.Pambuyo pomanga mphezi atachotsa kulowerera kwachindunji kwa mafunde a mphezi, chomangira mphezi sichimachotsa mphezi.Njira zowonjezera

3, womangayo ndiye kuti ateteze zida zamagetsi, ndipo chitetezo chachitetezo chimakhala choteteza zida kapena zida zamagetsi;

4. Chifukwa chakuti chomangira mphezi chikugwirizana ndi dongosolo lamagetsi lamagetsi, liyenera kukhala ndi ntchito yokwanira yotsekera kunja, ndipo kukula kwa maonekedwe ndi kwakukulu, ndipo chitetezo cha opaleshoni chikhoza kupangidwa chochepa chifukwa cha mphamvu yochepa.

Kusiyana pakati pa surge protector ndi arrester ndi:

1. Munda wogwiritsira ntchito ukhoza kugawidwa kuchokera ku mlingo wamagetsi.Mphamvu yamagetsi ya womangayo ndi <3kV mpaka 1000kV, low voltage 0.28kV, 0.5kV.

Mphamvu yamagetsi yachitetezo cha opaleshoni ndi k1.2kV, 380, 220 ~ 10V ~ 5V.

2, Chinthu chachitetezo ndi chosiyana: chomangirira ndikuteteza zida zamagetsi, ndipo chitetezo cha SPD choteteza nthawi zambiri chimateteza cholumikizira chachiwiri kapena kumapeto kwa zida zamagetsi ndi malupu ena opangira magetsi.

3. Insulation level kapena pressure level ndi yosiyana: kupirira voteji ya zipangizo zamagetsi ndi zipangizo zamagetsi si dongosolo la magnitude, ndipo voliyumu yotsalira ya chipangizo chotetezera cha overvoltage chiyenera kufanana ndi mlingo wopirira wa chinthu chotetezera.

4. Malo osiyana siyana oyika: Womangirira nthawi zambiri amaikidwa pa dongosolo kuti ateteze kulowerera kwachindunji kwa mafunde a mphezi ndi kuteteza mizere yapamwamba ndi zipangizo zamagetsi.Woteteza chitetezo cha SPD amaikidwa pa dongosolo lachiwiri, lomwe limachotsa mafunde a mphezi mu womangidwa.Pambuyo polowera mwachindunji, kapena womangayo alibe njira zowonjezera kuti athetse mphezi;choncho, womangidwayo amaikidwa pamzere wolowera;SPD imayikidwa kumapeto kwa malo kapena chizindikiro.

5. Osiyana otaya mphamvu: mphezi arrester chifukwa ntchito yaikulu ndi kuteteza mphezi overvoltage, kotero wachibale wake otaya mphamvu ndi lalikulu;ndi zipangizo zamagetsi, kutchinjiriza mlingo wake ndi ang'onoang'ono kwambiri kuposa zipangizo zamagetsi m'lingaliro lonse, m'pofunika SPD pa mphezi overvoltage Imatetezedwa ndi ntchito overvoltage, koma kudzera-otaya mphamvu zambiri ang'onoang'ono.(SPD kawirikawiri ili pamapeto ndipo sichidzalumikizidwa mwachindunji ndi mzere wapamwamba. Pambuyo pa malire apano a siteji yapamwamba, mphezi yamagetsi imakhala yochepa kwambiri, kotero kuti SPD yokhala ndi mphamvu yochepa yothamanga ikhoza kuteteza mokwanira. Mtengo wake siwofunika, chofunikira ndi kukakamiza kotsalira.)

6. Miyezo ina yotsekemera, kuyang'ana kwa magawo, ndi zina zotero zimakhalanso ndi kusiyana kwakukulu.

7. Wotetezera opaleshoni ndi woyenera kutetezedwa bwino kwa magetsi otsika kwambiri.Mitundu yosiyanasiyana yamagetsi ya AC/DC imatha kusankhidwa motengera mawonekedwe osiyanasiyana.Woteteza mphamvu yowonjezera mphamvu ali ndi mtunda waukulu kuchokera kutsogolo-kumapeto oteteza chitetezo, kotero kuti dera sachedwa oscillating overvoltage kapena over-voltage.Kutetezedwa kwamphamvu kwamphamvu kwa zida zama terminal, kuphatikiza ndi chitetezo cha pre-siteji, chitetezo chimakhala bwino.

8. Chinthu chachikulu cha womangayo chimakhala ndi zinc oxide (imodzi mwazitsulo za oxide varistor), ndipo chinthu chachikulu cha chitetezo cha opaleshoni chimakhala chosiyana malinga ndi msinkhu wa anti-surge ndi chitetezo chamagulu (IEC61312), ndi mapangidwe ake. zosiyana.Zomanga mphezi wamba ndizolondola kwambiri.

9. Kuyankhula mwaukadaulo, womangayo samafika pamlingo wachitetezo cha opaleshoni potengera nthawi yoyankha, kuletsa kupanikizika, chitetezo chokwanira, komanso mawonekedwe oletsa kukalamba.
