Does GIS have an impact on the environment during use compared to air-insulated ring main unit cabinets?
The air-insulated ring network cabinet, as the earliest type of ring network cabinet, has some characteristics that no longer meet the requirements for efficiency and environmental impact in power usage due to gradual technological advancements. Therefore, after technological iteration, gas-insulated ring network cabinets—GIS (gas insulated switchgear) emerged, which typically uses SF6 gas as the insulating medium. This type of ring network cabinet has a relatively smaller impact on the surrounding environment during actual use.
Firstly, because the structure of GIS is more compact and smaller in size, it is subject to fewer spatial constraints. It can be applied in various usage scenarios, and whether placed individually or in multiple units, it does not create much of a sense of disharmony with the environment.
In outdoor installation projects, attention must also be paid to the impact on the environment. Firstly, when heavy equipment is installed outdoors, there may be issues such as geological subsidence, while the lighter characteristics of GIS can reduce this risk. It occupies a small footprint, does not require a large foundation for stabilizing the equipment, and the area of land that needs to be excavated is small and shallow, thus minimizing the loss of surface soil and damage to flora and fauna in the natural environment. Additionally, when no longer needed, the backfill work is also minimal.
GISIt is also suitable for indoor projects, and its exquisite and minimalist appearance allows for widespread application indoors. At the same time, since noise issues must also be considered indoors, some air-insulated ring network cabinets typically generate noise when the circuit breaker operates. In contrast, GIS, due to its completely enclosed structure, produces relatively low noise, and SF6 gas is also a gas that can effectively absorb sound. Furthermore, the smaller operating mechanisms also generate lower noise.
GISAs a type of equipment using SF6 gas as an insulating medium, it inevitably faces atmospheric pollution issues. However, as fully insulated distribution equipment, the annual leakage rate is less than 0.05%, which has a minimal impact on the environment. Nonetheless, it is necessary to have gas leak detection devices or conduct regular leak checks to ensure that gas does not leak excessively and that the gas pressure and insulation performance within the gas chamber are not affected.
In summary, the appearance of GIS, whether indoors or outdoors, is not overly obtrusive or aesthetically displeasing. The potential issues caused by SF6 gas can also be largely disregarded, as comprehensive monitoring and timely handling can ensure that environmental pollution remains within a reasonable range and does not significantly impact the environment.
