Cov khoom siv high -voltage tseem ceeb yog dab tsi?

High- cov khoom siv hluav taws xob yog hais txog cov khoom siv hluav taws xob loj uas siv ncaj qha rau hauv cov txheej txheem ntawm kev tsim hluav taws xob, kev xa tawm, kev hloov pauv, thiab kev faib tawm, uas yog tsim los tiv taus cov hluav taws xob siab thiab cov dej loj, thiab ua haujlwm ntawm kev tswj xyuas hluav taws xob, kev tiv thaiv, kev ntsuas, thiab kev hloov. Cov khoom siv no feem ntau ua haujlwm hauv lub tshuab hluav taws xob nrog qhov ntsuas hluav taws xob ntawm 1 kV lossis siab dua. Feem ntau hom high-voltage thawj cov khoom siv feem ntau suav nrog cov hauv qab no:

1. High-Voltage Circuit Breakers (piv txwv li, roj Circuit Court breakers, SF₆ Circuit Court breakers, nqus Circuit Court breakers, thiab lwm yam)

• Muaj nuj nqi: Txuas lossis txiav ib lub voj voog nyob rau hauv ib txwm ua haujlwm; muaj peev xwm cuam tshuam sai sai thaum lub sijhawm ua txhaum thiab muaj arc -kev muaj peev xwm tua.

2. Disconnecting Switches (Isolators)

• Muaj nuj nqi: Feem ntau yog siv los cais cov khoom siv hluav taws xob thaum lub sijhawm tu, tsim kom pom qhov sib txawv ntawm huab cua; lawv tsis muaj arc-kev tua hluav taws muaj peev xwm thiab yuav tsum tau ua haujlwm tsuas yog nyob rau hauv tsis muaj -load lossis qis- cov xwm txheej tam sim no.

3. Load Switches

• Muaj nuj nqi: Muaj peev xwm txuas thiab txiav ib lub voj voog nyob rau hauv ib qho kev thauj khoom, txawm hais tias feem ntau tsis tuaj yeem cuam tshuam luv luv -circuit tam sim no; lawv feem ntau siv ua ke nrog fuses.

1. High-Voltage Fuses

· Muaj nuj nqi: Txhawm rau muab kev tiv thaiv los ntawm kev cuam tshuam ntawm Circuit Court - ntawm lub melting ntawm lub fuse caij - nyob rau hauv qhov tshwm sim ntawm overload los yog luv luv Circuit Court.

2. Surge Arresters (xws li Zinc Oxide Arresters)

· Muaj nuj nqi: Tiv thaiv cov khoom siv hluav taws xob los ntawm kev puas tsuaj los ntawm xob laim -vim hluav taws xob overvoltages lossis hloov overvoltages.

1. Busbars

· Muaj nuj nqi: Cov neeg siv khoom siv los sau thiab faib hluav taws xob hluav taws xob; feem ntau yog ua los ntawm tooj liab lossis txhuas, thiab muaj nyob rau hauv ntau hom xws li cov duab plaub lossis cov duab tubular.

2. Fais fab Cables

· Muaj nuj nqi: Siv rau kev sib kis thiab kev faib hluav taws xob; haum rau cov ntawv thov hauv av lossis ib puag ncig nrog qhov chaw txwv. Hom muaj xws li high-voltage cross- txuas cables, thiab lwm yam.

3. Insulators

· Muaj nuj nqi: Txhawb thiab ruaj ntseg nyob conductors thaum muab hluav taws xob rwb thaiv tsev; piv txwv xws li tus pin-hom insulators, suspension insulators, thiab lwm yam.

1. Tam sim no Transformer (CT)

• Muaj nuj nqi: Txhawm rau hloov pauv cov tam sim no siab mus rau qhov tsis tshua muaj kev siv los ntawm kev ntsuas cov cuab yeej thiab cov cuab yeej tiv thaiv.

2. Voltage Transformer (PT lossis VT)

• Muaj nuj nqi: Txhawm rau hloov pauv cov hluav taws xob siab mus rau qhov tsis tshua muaj hluav taws xob siv rau hauv kev ntsuas thiab kev tiv thaiv.

1. Fais fab Transformers

· Muaj nuj nqi: Siv los nce qib (qib- nce transformers) lossis nqis nqis (qib-kub transformers) voltage theem; lawv yog cov khoom tseem ceeb hauv lub zog hluav taws xob.

2. Instrument Transformers (Nrog rau hauv Kev Ntsuas thiab Kev Saib Xyuas; kuj tau faib ua cov cuab yeej tseem ceeb)

Cov ntsiab lus: High-voltage thawj cov khoom siv feem ntau suav nrog:

· Switching Equipment: Circuit Court breakers, disconnectors, load switches

· Cov cuab yeej tiv thaiv: Fuses, surge arresters

· Tam sim no -Cov Khoom Siv: Busbars, cables, insulators

· Cov khoom ntsuas: tam sim no transformers, voltage transformers

· Cov Khoom Siv Core: Fais fab transformers

Ua ke, cov khoom siv no tsim lub hauv paus ntawm siab -voltage fais fab tuag; lawv yog lub luag haujlwm rau kev sib kis, kev faib tawm, kev tswj hwm, thiab kev tiv thaiv hluav taws xob hluav taws xob, thiab ua ib qho tseem ceeb thiab tseem ceeb ntawm kev siv hluav taws xob engineering.
