The difference between environmental protection gas cabinets and other ring network cabinets
In order to enhance the protection of electrical equipment and ensure the safety of power supply, high-quality and efficient brand ring main units are used in most application scenarios. However, with the continuous research and development of electrical equipment, the projects applying ring main units have higher requirements for distribution equipment—environmental friendliness. Currently, ring main units using environmental gas as an insulation method have gradually replaced gas-insulated switchgear in many scenarios. Nevertheless, many people still do not know the differences between these two types of ring main units. The following will explain the differences between these two types of ring main units.
1. The essential differences between the two types of ring main units
The essential difference between the environmental gas cabinet and the gas-insulated switchgear lies in the different insulating media used. The commonly used insulating medium in gas-insulated switchgear is SF66 gas, which, if leaked, can cause pollution to the atmospheric environment. In contrast, Qingchang Electric uses an environmental gas that is primarily a nitrogen-based mixed gas, which can fundamentally solve the problem of SF66 gas leakage pollution, and also eliminates the need for periodic SF6pressure checks.
2.2. The differences in internal structure between the two types of ring main units
In the gas cabinet, the load switch, vacuum circuit breaker, and live busbar are all sealed in a closed stainless steel container filled with a certain pressure. In Qingchang Electric's environmental gas cabinet, the vacuum circuit breaker and vacuum load switch adopt a universal main structure design, which better ensures the consistency of the switch body; at the same time, unlike gas-insulated switchgear, the main circuit's on-off mechanism uses a spring mechanism, and the three-position isolation grounding switch adopts a mature knife switch structure, which prevents the risk of the main conductive circuit being energized and grounded.
The differences between these two types of ring main units go far beyond these. Other differences include the materials used in the mechanisms, the methods of connecting to the smart grid, and the cable wiring schemes, etc. How users choose between these two types of cabinets mainly depends on the actual usage location, needs, and environmental compatibility. If users have a clear environmental friendliness concept, it is recommended to consider including the environmental gas cabinet in their options.
