I. Equipment Definition
The SF₆ gas recovery device is a specialized equipment designed for safe and efficient recovery, purification, storage, and recharging of SF₆ gas within electrical equipment. It is a crucial device for ensuring the rational utilization and environmental treatment of SF₆ gas.
II. Core Application Objectives
Environmental Protection: SF₆ gas has an extremely strong greenhouse effect, with its global warming potential being 23,900 times that of carbon dioxide (CO₂). This device effectively prevents SF₆ gas from being directly discharged into the atmosphere, reducing environmental impact.
Economic Value: Through recovery and deep purification treatment, SF₆ gas can be reused, reducing the purchase of new gas, and thereby lowering overall operating costs.
Safety Assurance: It provides a safe working environment for the maintenance, repair, and decommissioning of electrical equipment, avoiding safety risks caused by gas leakage.
III. Main Application Scope
The SF₆ gas recovery device is mainly applicable to electrical equipment containing SF₆ gas. Specific application scenarios include:
Equipment Installation and Filling: For newly installed equipment or equipment after maintenance, vacuum treatment is carried out, and new gas or purified gas is filled;
Equipment Maintenance and Repair: Before partial disassembly of the equipment, the internal SF₆ gas is completely recovered to a dedicated storage container;
Fault Handling: When equipment fails and SF₆ gas decomposes, its purity decreases or water content exceeds the standard, the gas is recovered and purified;
Equipment Decommissioning and Scrap: For decommissioned equipment, SF₆ gas is thoroughly recovered for subsequent compliant treatment or regeneration utilization;
Gas Purification Treatment: For SF₆ gas with indicators such as water content and decomposition products exceeding standards, it is filtered and purified to restore it to the qualified standard.
IV. Core Application Industries
Power Industry (Core Application Field): Covers the daily operation and maintenance of substations of power grid companies at all levels, as well as the power plant booster stations and factory-use high-voltage electrical equipment of power generation enterprises;
Transmission and Transformation Equipment Manufacturing and Service Industry: Includes the gas treatment requirements of high-voltage switch equipment manufacturers during production and testing, as well as on-site installation, commissioning, and maintenance services of power engineering and maintenance service companies;
Rail Transit: Applicable to traction substations and power supply systems of high-speed railways and subways in electrified railways for the operation and maintenance of SF₆ gas equipment;
Industrial Sector: Targeting large industrial enterprises such as steel, metallurgy, and chemical industries, for the gas recovery and purification of SF₆ gas-insulated electrical equipment (such as electric arc furnaces) related to these equipment;
Research and Testing Institutions: Provide equipment testing, gas analysis, and related experimental process support for power science research institutes, quality inspection centers, and other units for SF₆ gas treatment.
