Musiyano pakati peSurge Protector uye Arrester

Vadziviriri veSurge uye vanosunga mheni hazvisi chinhu chimwe chete.

Kunyangwe ese ari maviri ane basa rekudzivirira overvoltage, kunyanya kudzivirira mheni overvoltage, kuchine misiyano yakawanda mukushandisa.

1. Chibatiso chine mazinga akawanda emagetsi, kubva pa 0.38KV low voltage kusvika 500KV UHV, nepo vadziviriri vekuvhiya kazhinji vane zvigadzirwa zvakaderera;

2. Musungwa akaiswa pane yekutanga system kudzivirira kupindira kwakananga kwemafungu emheni.Iyo yekuvhiya inodzivirira inonyanya kuiswa pane yechipiri system.Mushure mokunge muvharidzi wemheni abvisa kupindira kwakananga kwemafungu emheni, mubati wemheni haabvise mheni.Mamwe matanho

3, musungwa ndeyekuchengetedza midziyo yemagetsi, uye muchengeti wekuvhiya anonyanya kuchengetedza zviridzwa zvemagetsi kana zviridzwa;

4. Nemhaka yokuti chibatiso chemheni chakabatanidzwa kumagetsi ekutanga emagetsi, inofanira kuva nekushanda kwekunze kwekudzivirira kwekunze, uye ukuru hwekutaridzika hwakakura, uye muchengeti wekudzivirira anogona kuitwa muduku nekuda kwekuderera kwemhepo.

Musiyano uripo pakati pekusurge protector uye arrester ndewekuti:

1. Munda wekushandisa unogona kugoverwa kubva pazinga remagetsi.The rated voltage of the arrester is <3kV to 1000kV, low voltage 0.28kV, 0.5kV.

Iyo yakatemerwa voltage yekudzivirira kudzivirira ndeye k1.2kV, 380, 220 ~ 10V ~ 5V.

2, Chinhu chekudzivirira chakasiyana: chinosunga ndechekudzivirira midziyo yemagetsi, uye SPD surge mudziviriri kazhinji inodzivirira yechipiri chiratidzo loop kana kumagumo echiridzwa chemagetsi uye mamwe magetsi ekupa zvishwe.

3. Insulation level kana pressure level yakasiyana: the standstand voltage level yemagetsi emagetsi uye midziyo yemagetsi haisi urongwa hwehukuru, uye yakasara voltage ye overvoltage protection device inofanira kufanana nestandard voltage level yechinhu chekudzivirira.

4. Nzvimbo dzakasiyana dzekuisa: Musungwa anowanzoiswa pachirongwa chekudzivirira kupindira kwakananga kwemafungu emheni uye kudzivirira mitsetse yepamusoro uye zvigadzirwa zvemagetsi.Iyo SPD surge protector yakaiswa pane yechipiri system, iyo inobvisa mafungu emheni mune inosunga.Mushure mekupinda kwakananga, kana musungwa haana matanho ekuwedzera ekubvisa mheni wave;saka, musungwa anoiswa pamutsetse unouya;iyo SPD yakaiswa pamagumo ekubuda kana chiratidzo chedunhu.

5. Kusiyana kwekuyerera kwesimba: mheni inosunga nokuti basa guru nderokudzivirira mheni kudarika, saka simba rayo rinoyerera rakakura;uye nokuda kwemidziyo yemagetsi, chiyero chayo chekudzivirira iduku zvikuru pane midziyo yemagetsi mupfungwa yakajairika, inofanirwa SPD pamheni overvoltage Inodzivirirwa nekushanda overvoltage, asi kuburikidza-kuyerera kwayo simba kazhinji iduku.(SPD inowanzova pamagumo uye haizobatanidzi zvakananga kumutsara wepamusoro. Mushure memuganhu wezvino wepamusoro wepamusoro, mheni yemazuva ano yakave yakaganhurirwa kune yakaderera kukosha, kuitira kuti SPD ine diki yekuyerera inokwanisa kudzivirira zvizere. kuyerera. Kukosha hakuna kukosha, chakakosha isimba rinosara.)

6. Mamwe mazinga ekudzivirira, kutarisa kwezviyero, nezvimwewo zvinewo kusiyana kukuru.

7. Mudziviriri wekudzivirira akakodzera kuchengetedzwa kwakanaka kwepasi-voltage power supply system.Yakasiyana-siyana AC / DC magetsi emagetsi anogona kusarudzwa zvichienderana neakasiyana maratidziro.Iyo yekudzivirira yemagetsi inodzivirira ine chinhambwe chikuru kubva kumberi-yekupedzisira surge mudziviriri, kuitira kuti dunhu rinowanzoita oscillating overvoltage kana imwe over-voltage.Yakanaka simba rekudzivirira yekudzivirira yemidziyo yekupedzisira, yakasanganiswa neye pre-stage yekuvhiya mudziviriri, iyo yekudzivirira maitiro iri nani.

8. Chinhu chikuru chemusungwa chinowanzoita zinc oxide (imwe yesimbi oxide varistor), uye chinhu chikuru chekudzivirira chidziviriro chakasiyana maererano nehuwandu hwekudzivirira uye kuchengetedzwa kwechikwata (IEC61312), uye dhizaini iri. zvakasiyana.Mabatiro emheni akajairwa akanyanya kujeka.

9. Neunyanzvi kutaura, musungwa haasviki pamwero wekudzivirira kwekuvhiya maererano nenguva yekupindura, kudzvinyirira kumisa mhedzisiro, yakazara kudzivirira maitiro, uye anti-kuchembera maitiro.
