I. Equipment Definition
The SF? gas recovery device is a specialized equipment designed for safe and efficient recovery, purification, storage, and recharging of SF? gas within electrical equipment. It is a crucial device for ensuring the rational utilization and environmental treatment of SF? gas.
II. Core Application Objectives
Environmental Protection: SF? gas has an extremely strong greenhouse effect, with its global warming potential being 23,900 times that of carbon dioxide (CO?). This device effectively prevents SF? gas from being directly discharged into the atmosphere, reducing environmental impact.
Economic Value: Through recovery and deep purification treatment, SF? 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 SF? gas recovery device is mainly applicable to electrical equipment containing SF? 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 SF? gas is completely recovered to a dedicated storage container;
Fault Handling: When equipment fails and SF? gas decomposes, its purity decreases or water content exceeds the standard, the gas is recovered and purified;
Equipment Decommissioning and Scrap: For decommissioned equipment, SF? gas is thoroughly recovered for subsequent compliant treatment or regeneration utilization;
Gas Purification Treatment: For SF? 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;
