Introduction
SF6 gas used in electrical switchgear and control equipment for over 30 years. It is mainly used for rated voltage above 1kV until the
There has manufactured the highest rated voltage switchgear and control equipment. It is estimated that there are several million units filled with different types of
SF6 units in operation.
According to GB/T 11022, there are three kinds of gas system is technically available.
--- Controllable pressure systems;
Note 1. Because unacceptable leak rate (see GB 7674), the new equipment is no longer controllable pressure systems.
--- Closed pressure systems. For the standard modern electrical equipment per year leak rate is 0.5% and 1% each inflatable compartments;
--- Sealed pressure system. For a modern medium voltage electrical equipment (commercially known as "lifelong seal products" or "hermetically sealed system"), the seal
Sealing pressure of the system to the provisions of its expected life. Leakage performance with respect to life expectancy by the manufacturer to regulate
set. Preferably of 20 years, 30 years and 40 years.
Note 2. In order to meet the anticipated requirements of life, that the annual rate of the leak sealed pressure system is less than 0.1%.
Electrical switching and control equipment used in the long-term experience has shown that SF6, as long as the establishment and comply with certain basic precautions and procedures
Order, to benefit the operation, safety and working environment, for example.
--- Safe operation of equipment;
--- Optimization of resources and tools;
--- Minimize equipment downtime of;
--- SF6 Processing Standards trainers;
--- Emissions during gas processing operation is reduced to below the limit of physical function;
--- Avoid any deliberate emissions, such as emissions into the atmosphere;
--- During the transfer, use, operation and end of life processing SF6 consumption and emissions to a minimum.
Recently, on the latest technology in SF6 switchgear and control practices recommended by the equipment has been studied by the committee CIGREB3
B3.02 Working Group will be published [1]. This information is used to develop this standard.
High-voltage switchgear and control equipment for sulfur hexafluoride
(SF6) for use and handling
1 Scope
This standard applies to high-voltage switchgear and control equipment SF6 processing installation, transfer, normal and abnormal operation, at the end of life
Procedures set of safety and the environment.
Should be considered in these procedures is to ensure the safety of personnel working SF6 and SF6 emissions will be the most minimal to the environment reduced the number of
Low demand.
This standard is generally applicable to a mixed gas of SF6.
Note 1. In order to facilitate the use of this standard, the voltage range of high-voltage switchgear in the usual sense generally refers to the rated voltage of 3.6kV and above. Practical application
The rated voltage range is typically medium voltage switchgear is 3.6kV ~ 63kV; Rated voltage range of high-voltage switchgear is 72.5kV ~
252kV; rated voltage range is EHV switchgear 363kV ~ 800kV; rated voltage range of special high-voltage switchgear is 1100kV
And above.
Note 2. The entire Standard, the term "electrical equipment" stands for "high-voltage and medium-voltage switchgear and/or control devices."

3 Terms and Definitions
GB/T 2900.20 define the following terms and definitions apply to this document.
Note. Many different types of switches and control equipment are used SF6 gas as insulation and/or arc-quenching medium.
3.1
