It is the nominal voltage 12kV, the high-pressure indoor switch apparatus of the three-phase alternating current 50Hz to sum up the high-pressure vacuum circuit breaker of ZN28-12 indoor. Products accord with the intersection of GB1984-89 and standard, the intersection of product and overall structure this body and actuating mechanism install integratively and the intersection of switch and body and actuating mechanism install two kinds of forms separately for switch. The integrative type structure is ZN28-12 basic model; The separated structure is ZN28A-12 type, accommodates various fixed switch cabinets, such as GG-1A (Z) XGN2A10( Z) When; This product very matched CD17, magnetic operating mechanism and energy-storing type operating mechanism of CT17, Model CT19 spring of direct current of Model CD10A. Operating range: ZN28-12 indoor high-pressure vacuum circuit breaker is suitable for industrial and mining enterprises, power plant's and converting station's using for electric protection and control of facility. This circuit breaker contains CT19 spring operating mechanism or CD17 electromagnetic operating mechanism, can already install and use alone, can also pack into the fixed cabinet or box cupboard and use, and is frequently suitable for operating and more harsh working condition. The air temperature is less than +40oC, lower limit around the service conditions; -25oC is above sea level are less than 2000M Humidity; The mean value on day of the relative humidity is not greater than 95% months mean value is not greater than 90%; The mean value on day of water vapour pressure is not greater than 2. 2KPA, monthly mean value is not greater than 1.8KPA The ambient air should have been often moved vigorously by the corrosivity or imflammable gas, obvious pollution of vapor It is in vogue that the contact apparatus moves, it is not greater than 5o to install level and lateral dip angle Go beyond the requirement for the above-mentioned conditions, by users with making unit protocol.
