UKUKHETHWA KWESITSHINTSHI SOMTHWALO WE-VOLTAGE OPHILAYO

Okokuqala, kuyimfuneko ukuqonda indawo yokusetyenziswa. Iswitshi yomthwalo we-high-voltage sisixhobo sombane esisebenza phakathi kwe-high-voltage circuit breaker kunye ne-high-voltage isolation switch. Iswitshi yomthwalo we-high-voltage idla ngokusetyenziswa kuthotho kunye ne-high-voltage fuse; isetyenziselwa ukulawula i-power transformer. Iswitshi yomthwalo we-high-voltage inesixhobo esilula sokucima i-arc, kuba inokuvula nokucima i-load current ethile kunye ne-overload current. Nangona kunjalo, ayinakuyikhupha i-short-circuit current, ngoko ke isetyenziswa kuthotho kunye ne-high-voltage fuse yokukhusela i-short-circuit.

Amanqaku okukhetha:

1. Umlinganiselo wamandla ombane, shiya umda omalunga ne-30%

2. I-voltage elinganisiweyo: efanayo okanye engaphezulu kune-voltage yokwenyani

3. Umsinga oqhekekayo kufuneka uhambelane neemfuno zoyilo

4. Isantya sokusebenza kufuneka sidlule kwiimfuno zoyilo malunga ne-10%

5. Umthamo uhambelana neemeko zokwenyani zesiza

6. Ukuthembeka, ukhuseleko kuqala

Yintoni umsebenzi ophambili wesitshixo somthwalo we-voltage ephezulu?

Iswitshi yomthwalo we-high-voltage sisixhobo sombane esikhethekileyo kwisekethe ye-high-voltage esetyenziselwa ukudibanisa okanye ukukhupha umsinga womthwalo phantsi kwe-voltage elinganisiweyo. Nangona inesixhobo sokucima i-arc, amandla ayo okucima i-arc abuthathaka, kwaye inokunqumla kwaye idibanise umsinga womthwalo oqhelekileyo kuphela, kodwa ayinakusetyenziselwa ukucima umsinga we-short-circuit. Kwiimeko eziqhelekileyo, iswitshi yomthwalo isetyenziswa kunye ne-fuse ye-high-voltage, kwaye i-fuse idlala indima yokukhusela i-short-circuit.
