Fully Insulated Fully Enclosed Inflatable Metal Switch Equipment
Fully insulated and fully enclosed inflatable metal switchgear is a new type of power equipment, which adopts inflatable insulation technology and fully enclosed design, and is widely used in power systems. This paper will discuss the fully insulated and fully enclosed inflatable metal switchgear, and discuss its working principle, characteristics and advantages, and its application in power system.
1. Working principle
fully insulated and fully enclosed inflatable metal switchgear adopts inflatable insulation technology, and uses dry gas (such as nitrogen) to fill the inside of the equipment to form an insulating airbag, thus realizing the fully enclosed design and insulation protection of the equipment. When the equipment fails, the insulating airbag can effectively isolate the fault and protect the equipment and system.
2. Features and advantages
- fully enclosed design: The fully insulated and fully enclosed design effectively prevents the influence of external environmental factors on the equipment and improves the stability and reliability of the equipment.
- inflatable insulation: Inflatable insulation technology has the advantages of fast arc extinguishing and efficient isolation, which can effectively protect the safety of equipment and personnel.
- Environmental protection and energy saving: The use of dry gas as the insulating medium avoids the negative impact of traditional SF6 gas on the environment and meets modern environmental protection requirements.
- Easy operation and maintenance: The fully enclosed design reduces the maintenance of the equipment, and the inflatable insulation technology makes the operation of the equipment easier.
3. Application in power system
fully insulated and fully enclosed inflatable metal switchgear in the power system has a wide range of applications, mainly reflected in the following aspects:
- substation: In substations, fully insulated and fully enclosed inflatable metal switchgear, as an important switchgear, can realize the distribution, control and protection of the power system and improve the reliability of power supply.
- distribution system in the urban power distribution system, fully insulated and fully enclosed inflatable metal switchgear can play the role of overload protection and short circuit protection, and improve the safety and stability of the power distribution system.
- Industrial electricity in the industrial field, fully insulated and fully enclosed inflatable metal switchgear can be used in the power system of large industrial equipment to ensure stable power supply for industrial production.
4. Case analysis
taking a city substation as an example, after the introduction of fully insulated and fully enclosed inflatable metal switchgear, the failure rate of the equipment is significantly reduced, the reliability of power supply is improved, and the operating efficiency and safety of the equipment are significantly improved, which provides a strong support for the city's power supply.
