12Kv / 24KV Indoor Environmental Protection Gas Insulated Metal - Enclosed Switchgear
1. Green and environment-friendly:
It uses N2 gas or dry air as the main insulating medium, no green house gas emission.The product material can be recycled more than 90% after the end ot its life cycle.
2. Strong environmtal adaptability :
All high-pressure components are sealed in the inflatable metal enclosure. thus it has the stable insulation performance especially tor high altitude, cold. humid,dirty and other harsh envronment.
3. Safe and reliable.
It adopts the micro-postive pressure gas insulaton to prevent moisture infiltraion. It can still be safe and reliable under the zero gauge pressure.Equipped wih three-position switch observaion window, The status of disconnecor and earthing swich can be obseved directly.
4. High reliability electrical components Mantenance free
The vacuum interrupter has a long service life and maintenance free;
The high voltage insulating parts are not affected by the external environment and aging resistant
It retains the size-advantage of SF6 switchgear to reduce the space requirement and minimize the operating cost.
6. Modular Design:
Circuit breaker (or load switch) and three-positon disconnector are designed integrally, Circuit breaker
mechanism and thre-epositon disconnector mechanism are modular and intergrated design; It adopts moduiar plug-in technology to realize the electrical conection between each functional compartments
or air boxes , thus it is very convenient for the on-site installation, and very flexible to realize different types of electrical wiring diagrams
Besides te basic microcomputer integrated protection function, it also can provide data collection and detection functions for gas pressure, temperature, micro -water and current ,voltage etc... and has a friendly interface
Product Overall Dimension
(width height * depth): 400 (500) mm * 1640mm * 860mm
It offers two options of uper isolating and lower isolating for users to choose .It can realize cable-side earthing switch directly to close, It complies with the five prevention operating procedures put forward by Ministry of Power, also in line with the users operaing habits.
10. High electrical parameter
Circuit breaker with rated current up to 1250A ,breaking current 31.5kA and altitude lower than 3000 meters.
