Overview
XGN-12 series solid all-insulated closed ring network switchgear is a kind of solid insulation vacuum switchgear with full insulation, full seal and maintenance-free. All high-voltage live parts are insulated Excellent epoxy resin material is cast and molded, which organically combines the vacuum arc extinguishing chamber, main electric circuit and insulation support into a whole, and the functional units are connected by fully insulated solid bus bars. Therefore, the whole Each switchgear is not affected by external environment, which can ensure the reliability of equipment operation and the safety of operators.
The ring network cabinet has the characteristics of simple structure, flexible operation, reliable interlocking and convenient installation. It is suitable for 50Hz and 12 kV power systems and is widely used in industrial and civil cable ring networks and distribution Network terminal engineering, as the receiving and distribution of electric energy, is especially suitable for power distribution in urban residential areas, small substations, opening and closing stations, cable branch box, box-type substations, industrial and mining enterprises, shopping malls and machines Field, subway, wind power generation, hospitals, stadiums, railways, tunnels and other places.
Because the product has the advantages of full insulation, full sealing and full shielding, it is especially suitable for high altitude, high temperature, damp heat, severe cold and severe pollution.
Cotegory
According to switch types, it is divided into load switch with grounding assembly (c module for short), load switch without grounding assembly (CB module for short) and circuit breaker with grounding assembly (v module for short). Circuit breaker without grounding assembly (VB module for short), circuit breaker contact switch (VZ module for short), load switch+fuse combination electrical switch assembly (F module for short) and isolating switch assembly (g module for short).
Model and meaning
Conditions of use
◇ Ambient temperature: -45℃ ~+45℃ ;
◇ Humidity: maximum average relative humidity, with daily average ≤ 95% and monthly average ≤ 90%；
◇ Altitude: ≤ 2000 meters；
◇ Seismic resistance: 8 degrees；
◇ Protection grade: live body seal IP67, fuse barrel IP67, switch cabinet shell IP3X。
Application field
◇ Low temperature and cold area: there is no application of SF6 gas, so it can run normally at -45 ℃ without considering the low temperature operation of SF6 gas；
◇ Plateau area: it is unnecessary to consider the influence of plateau atmospheric pressure on insulation performance；
◇ Strong sandstorm area: The safety protection level of solid insulation ring network cabinet body is IP67, and the control loop room adopts special treatment to ensure long-term operation in strong sandstorm area；
◇ Coastal wet pool area: sealed with epoxy resin, resistant to moisture and salt spray corrosion, ensuring long-term use in coastal areas；
◇ Areas with high environmental protection requirements: The influence of SF6 gas on atmospheric warming has been paid great attention to, and SF6 gas has been eliminated in solid ring network cabinets, thus causing no pollution and harm to the environment and people；
◇ In smart grid: since the main switch and isolating switch can be electrically operated, the intelligent controller developed by our company can be selected for remote control, telemetry and telecommunication of switching equipment and substation site, which can not only carry out decentralized control, but also facilitate centralized control。
