Learn More About SF6 Gas Recovery And Treatment Equipment

SF6 gas, or sulfur hexafluoride, has been widely used in the electrical industry since the 1950s due to its excellent insulating and arc – extinguishing properties. However, with increasing environmental awareness and regulatory requirements, the proper handling of SF6 gas, especially through recovery and treatment equipment, has become crucial.​

Applications of SF6 Gas​

SF6 gas is predominantly used in high – voltage and extra – high – voltage electrical equipment. In high – voltage circuit breakers, it serves as an efficient arc – extinguishing medium, replacing oil and compressed air in many applications. It is also used in gas – insulated switchgear (GIS), which significantly reduces the footprint of power distribution installations compared to traditional open – air high – voltage distribution devices. Additionally, SF6 – insulated transformers offer fire – and explosion – proof advantages, making them suitable for use in densely populated areas and high – rise buildings.​

The Need for SF6 Gas Recovery And Treatment Equipment​

As SF6 is a potent greenhouse gas with a high global warming potential, it is essential to minimize its release into the atmosphere. SF6 gas recovery and treatment equipment plays a vital role in this regard. When electrical equipment needs maintenance, repair, or decommissioning, the SF6 gas within must be safely and efficiently removed. This not only helps in reducing environmental impact but also allows for the reuse of the valuable SF6 gas.​

Functions of SF6 Gas Recovery And Treatment Equipment​

Gas Recovery: The equipment is designed to extract SF6 gas from electrical devices. It can recover gas even from equipment with low residual pressure, ensuring maximum gas retrieval. For example, some advanced recovery units can bring the gas pressure in GIS to as low as 53 Kpa.​

Purification: During the recovery process, the gas may contain impurities such as moisture, decomposition products, and oil. SF6 gas recovery and treatment equipment is equipped with purification systems. These often include filter – adsorption systems that can effectively remove these contaminants, ensuring that the recycled SF6 gas meets the required quality standards.​

Storage: The recovered and purified SF6 gas needs to be stored properly. The equipment can store the gas in liquid form, which significantly reduces the storage volume. Some units have a theoretical liquid storage capacity of up to 150 KG.​

Re – charging: Once the electrical equipment has been serviced, the treated SF6 gas can be re – charged back into the device. The equipment ensures accurate and safe re – charging, maintaining the performance of the electrical equipment.​

Advantages of SF6 Gas Recovery And Treatment Equipment​

Environmental Protection: By preventing the release of SF6 gas into the atmosphere, these devices contribute significantly to environmental protection. They help in reducing the greenhouse gas effect and complying with international environmental regulations.​

Cost – effectiveness: Recycling SF6 gas is more cost – effective than constantly purchasing new gas. The recovery and treatment equipment enable the reuse of the gas, reducing operational costs in the long run.​

Efficient and Safe Operation: Modern SF6 gas recovery and treatment equipment are designed with user – friendly interfaces and safety features. For instance, they may have built – in phase – sequence protectors to prevent motor reversal, and temperature protection systems to ensure operation even in low – temperature environments.​

In conclusion, SF6 gas recovery and treatment equipment are essential for the sustainable operation of the electrical industry. They balance the need for the continued use of SF6 gas in high – performance electrical equipment with environmental responsibility. As technology continues to advance, these devices will only become more efficient and effective in handling SF6 gas.
