XGN-12 Intelligent solid insulation cabint

Overview

XGN-12 series solid fully insulated and closed ring network switchgear is a kind of solid insulation vacuum switchgear with full insulation, full sealand maintenance-free. All high-voltage live parts are casted and moulded using epoxy resin material with excellent insulating property, which organically integrates the vacuum arc extinguishing chamber, main electric circuit and insulation support, and the functional units are connected by fully insulated solid busbars. Therefore, the whole 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 12kV 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. And it is especially suitable for power distribution in urban residential areas, small substations, opening and closing stations, cable branch boxes, box- type substations, industrial and mining enterprises, shopping malls and airpots, subways, windpower 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 the places with high altitude, high temperature, damp heat, severe cold and severe pollution.

Category

According to switches type, it is divided into load switches with grounding assembly (C module for short), load switches without grounding assembly (CB module for short)and circuit breakers with grounding assembly (V module for short),   circuit breaker without grounding assembly (VB module for short), circuit breaker interconnection switch (VZ module for  short), load switch+fuse combination electrical switch assembly (F module for short)and isolating switch assembly (G     module for short).

Environmental  conditions

a Ambient temperature:-45°C to +45℃;
b Humidity:Maximum average relative humidity, with a daily average of 95%or below and a monthly average of 90%or below;
C Altitude:below 2000 meters;
d Seismic resistance:8 degree
e Protection level:live body seal IP67, fuse barrel IP67, switch cabinet shell IP3X.

Application  fields

+Low temperature and cold areas:there is no application of SF6 gas, so it can run normally at -45℃ without considering the low temperature operation of SF6.
+Plateau area:it is unnecessary to consider the influence of plateau atmospheric pressure on insulation performance.
+Strong sandstorm area:the safety protection level of the solid insulation ring network cabinet body is IP67, and the control loop room adopts special treatment to ensure long-term operation in strong sandstorm areas.
+Coastal wet 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 the smart grid:since the main switch and isolating switch can be electrically operated, remote control, telemetry, and telecommunication of switching equipment and substation sites can be realized, which can not only carry out decentralized control, but also facilitate centralized control.
