Overview
GCK low-voltage withdrawable switchgear inoshandiswa zvakanyanya mumagetsi emagetsi, metallurgical rolling, petrochemical, light industry uye textile, zviteshi, zvivakwa, mahotera nedzimwe nzvimbo se AC matatu-phase mana-waya kana mashanu-waya system, voltage 380V, 660V, frequency 50Hz, yakatemerwa Inoshandiswa pakugovera magetsi uye mota yepakati pekutonga mumasisitimu emagetsi emagetsi ane mafungu e5000A uye pazasi.
GCK ndeyepamusoro-yepamusoro-yakaderera-voltage switchgear yakaunganidzwa uye yakaunganidzwa, uye yakagadzirirwa kusangana neanotevera zviyero:
National standard GB7251.1-2005 "Low-voltage switchgear"
International standard IEC60439.1-1992 "Low-voltage switchgear uye control equipment"
Muenzaniso Zvinoreva
Normal Use Environment
◆ The ambient air tembiricha haisi yakakwirira kupfuura +40 ℃, kwete yakaderera pane -5 ℃, uye avhareji tembiricha mukati maawa 24 haisi yakakwirira kupfuura +35 ℃;
◆ Kupisa kwepamusoro hakupfuuri 50% pahupamhi hwepamusoro + 40 ℃, uye kutonhora kwepamusoro kunobvumirwa pakudzika kwakadzika, zvakadai se90% pa +20 ℃;
◆ Mhepo yakachena, hapana gasi rinoparadza uye rinoputika, hapana guruva rinoita uye rinodzivirira:
◆ Muchiitiko chekusazununguka kwakakosha uye kuzununguka kwekudengenyeka, kuiswa kwakadzikama, kutaridzika hakufaniri kunge kwakakura kudarika 5 degrees;
◆Kukwirira hakupfuuri 2000 metres;
◆ Switchgear inokodzera kutakura uye kuchengetedza kune kutonhora kunotevera: -25 ° C kusvika + 55 ° C, isingapfuuri + 70 ° C munguva pfupi (kwete maawa anopfuura 24);
◆Vashandisi vanofanira kutaurirana nemugadziri kana zvisungo zviri pamusoro zvisingakwanisike.
