I-11KV Compact Subrations

Ukuqalisa

Isidingo esingapheli sogesi othembekileko emhlabathini wethu owandayo owandayo futhi othuthukile udinga amanethiwekhi okusatshalaliswa kwamandla asebenzayo futhi aqinile. I-11KV Compact Support (CSS), owaziwa nangokuthi afakwe esikhundleni esihlanganisiwe (ama-PS) noma izinto ezihlanganisiwe (i-USS).

Le mihlangano yezobunjiniyela imele ukuvela okubalulekile ekwakhiweni okuphezulu, okuhlanganisa izakhi ezibalulekile kuyunithi elilodwa, elihlolwe ngohlobo, olukhethwe efektri.

Kuyini ukufakwa okuhlangene (CSS)?

Ukufakwa okuhlangene empeleni kungumhlangano wokuzifaka kagesi ozinemininingwane uqobo, ohlanganiswe futhi uhlolwe endaweni efektri ngaphambi kokuthunyelwa esizeni ukuze kufakwe.

Ngqo ngeI-11KV ecwengekile, umsebenzi oyinhloko ukuthola amandla kagesi kuzinga le-11KV Medium Voltage (MV), uliguqule i-400V / 240V, noma i-2415V, noma i-315V, noma i-LV yamandla e-LV ngokujwayelekile emhlabeni jikelele) Ukuhlanganiswa kweyunithi eyodwa, ehlanganisiwe, nevaliwe.

Le design Philosophy Shift inikezela ngezinzuzo eziningi, ihambisa okuningi komhlangano oyinkimbinkimbi kanye nomsebenzi wokuhlola kusuka emkhakheni ube yindawo ephelele yefektri, inomthelela omkhulu wephrojekthi kanye nokuqinisekiswa kwekhwalithi.
