Kusiyana pakati pa surge protector ndi arrester

1. Omanganso ali ndi ma voltages angapo, kuchokera ku 0.38kv low voltage kufika ku 500kV UHV, pamene zipangizo zotetezera mawotchi nthawi zambiri zimakhala zotsika kwambiri;

2. Ambiri mwa omangawo amaikidwa pa dongosolo loyamba kuti ateteze kuukira kwachindunji kwa mafunde a mphezi, pamene ambiri otetezera opaleshoni amaikidwa pa dongosolo lachiwiri, lomwe ndilo gawo lowonjezera pambuyo pa womangidwayo atachotsa kuukira kwachindunji kwa mphezi, kapena pamene womangayo sachotsa mphezi kwathunthu;

3. Arrester arrester imagwiritsidwa ntchito kuteteza zipangizo zamagetsi, pamene chitetezo cha opaleshoni chimagwiritsidwa ntchito kwambiri kuteteza zida zamagetsi kapena mamita;

4. Chifukwa chomangirira chikugwirizana ndi magetsi oyambirira, chiyenera kukhala ndi ntchito yokwanira yotsekera kunja, ndipo kukula kwa maonekedwe ndi kwakukulu.Chifukwa chitetezo cha opaleshoni chimalumikizidwa ndi magetsi otsika, kukula kwake kungakhale kochepa kwambiri.

Dongosolo lachitetezo choteteza 1. Kabati yowongolera kutembenuka pafupipafupi iyenera kuwonjezeredwa;2. Control cabinet pogwiritsa ntchito vacuum circuit breaker iyenera kuwonjezeredwa;3. Kusinthana komwe kukubwera kwamagetsi amagetsi kuyenera kuwonjezeredwa

4. Makabati ena owongolera sangawonjezedwe.Zoonadi, ngati pali malo a bajeti otetezeka, akhoza kuwonjezeredwa

Zida zoteteza ma Surge nthawi zambiri zimagawidwa m'mitundu iwiri: mtundu wachitetezo chamagalimoto ndi chitetezo chamagetsi!

Chipangizo chodzitchinjiriza chotsatira chimatengera mtundu wa varistor wokhala ndi mawonekedwe abwino kwambiri osagwirizana.Munthawi yanthawi zonse, chipangizo chodzitchinjiriza chokwera chimakhala chokana kwambiri, ndipo kutayikira kwapano kuli pafupifupi ziro, kuti zitsimikizire kuti mphamvu yamagetsi yomangirira mphamvu imakhala yokwanira.Pamene kuwonjezereka kukuchitika mumagetsi opangira magetsi, chokongoletsera zitsulo zosapanga dzimbiri ndi chitetezo cha opaleshoni chidzayendetsa nthawi yomweyo mu nanoseconds kuchepetsa matalikidwe a overvoltage mkati mwa zida zotetezeka zogwirira ntchito.Pa nthawi yomweyi, mphamvu ya overvoltage imatulutsidwa.Kenako, mtetezi mwamsanga amakhala mkulu kukana boma, kotero sikumakhudza yachibadwa magetsi a dongosolo mphamvu.

Chida chachitetezo cha Surge (SPD) ndi chida chofunikira kwambiri pakuteteza mphezi pazida zamagetsi.Poyamba ankatchedwa "surge arrester" kapena "overvoltage protector", chidule cha SPD mu Chingerezi.Ntchito ya chipangizo chachitetezo chachitetezo ndikuchepetsa kuchulukitsitsa kwakanthawi mu chingwe chamagetsi ndi chingwe chotumizira chizindikiro mkati mwa voteji yomwe zida kapena dongosolo limatha kunyamula, kapena kutulutsa mphezi yamphamvu pansi, kuteteza zida zotetezedwa kapena dongosolo. kuti asawonongeke ndi kukhudzidwa.

Mitundu ndi kapangidwe ka zida zodzitchinjiriza pakuchita opaleshoni ndizosiyana malinga ndi ntchito zosiyanasiyana, koma ziyenera kukhala ndi chinthu chimodzi chochepetsa mphamvu yamagetsi.Zomwe zimagwiritsidwa ntchito mu SPD zimaphatikizira kutulutsa kotulutsa, chubu chotulutsa mpweya, varistor, kupondereza diode ndi coil coil.
