Isishwankathelo
Iimveliso zethu ezintsha, i-NVS1-12 ichungechunge lwangaphakathi lwe-high-voltage vacuum circuit breakers lusetyenziselwa ii-switchgears kwi-12kV inkqubo yamandla, njengeyunithi yokulawula kunye nokukhusela izixhobo zombane kumashishini oshishino kunye nemigodi, izityalo zamandla kunye neendawo ezincinci. Ngenxa yeenzuzo ezikhethekileyo ze-vacuum circuit breaker, ifanelekile ngokukodwa kwimisebenzi eyenziwa rhoqo efuna ukulinganisa ukusebenza ngoku, okanye iindawo apho i-short-circuit current yaphuka amaxesha amaninzi. I-breaker circuit ithatha uyilo oludibeneyo lwendlela yokusebenza kunye nomzimba we-circuit breaker. Ezi zimbini ziyisakhiwo sangaphambili nasemva, esinomsebenzi othembekileyo wokudibanisa. I-breaker circuit ingasetyenziselwa njengeyunithi yokufakela esisigxina. Isenokuxhotyiswa ngelori ye-chassis kwiyunithi yenqwelo yesandla.
