Environmental protection gas atmospheric pressure closed insulated ring network cabinet it is a kind of power equipment with environmental protection gas as insulation medium and closed design. It is widely used in power system and has the advantages of safety, high efficiency and environmental protection. This paper will focus on the environmental protection gas atmospheric pressure closed insulated ring network cabinet to discuss its working principle, advantages and characteristics and application in power system.

1. Working principle

environmental protection gas atmospheric pressure closed insulation ring network cabinet using environmental protection gas (such as SF6 alternative gas) as the insulation medium, through the closed design and normal pressure operation, to achieve the safe operation of power equipment and insulation performance. When a fault occurs in the power system, the environmentally friendly gas can quickly extinguish the arc and effectively protect the power equipment and system.

2. Advantages and characteristics

• environmental protection: The use of environmentally friendly gas as the insulating medium avoids the negative impact of traditional SF6 gas on the environment and meets modern environmental protection requirements.
• Efficiency: The closed design and normal pressure operation make the environmental protection gas normal pressure closed insulated ring network cabinet have higher operating efficiency and reliability, and reduce the operation and maintenance costs.
• Security environmental protection gas atmospheric pressure airtight insulated ring network cabinet is designed to pay attention to safety, which can effectively prevent faults and accidents in the power system and ensure the safe and stable operation of the power system.

3. Application in power system

environmental protection gas atmospheric pressure sealed insulated ring network cabinet has a wide range of applications in the power system, mainly reflected in the following aspects:

• distribution system in the urban power distribution system, the environmental protection gas atmospheric pressure sealed insulated ring network cabinet can play the role of overload protection, short circuit protection, etc., to improve the reliability and stability of the power system.
• Substation in the substation, the environmental protection gas atmospheric pressure sealed insulated ring network cabinet as an important power distribution equipment, can realize the distribution and control of power, to ensure the quality of power supply and power supply reliability.
• Industrial electricity in the industrial field, the environmental protection gas atmospheric pressure sealed insulated ring network cabinet can be applied to the power consumption system of large industrial equipment to provide stable power support for industrial production.

4. Case analysis

taking a city substation as an example, after the introduction of environmental protection gas atmospheric pressure closed insulation ring network cabinet, the failure rate of the power system is significantly reduced, the maintenance cost is reduced, the operation efficiency is improved, the power supply reliability of the substation is significantly improved, and the power supply of the city is escorted.
