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 in sulfur hexafluoride (SF6) The impact of the release of gases on the environment and health1 ScopeThis standard applies to the high-voltage switchgear and control equipment, normal and abnormal operation and environmental safety as well as personnel and handling SF6 Yung procedures, including the storage and transport as well as training of personnel of SF6. 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 applications, Rated voltage range is typically medium voltage switchgear is 3.6kV ~ 63kV; Rated voltage range of high-voltage switchgear is 72.5kV ~ 252kV; ultrahigh Rated voltage range voltage switchgear is 363kV ~ 800kV; rated voltage range UHV 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." In this standard, may not contain all the existing rules on SF6 (procedure), it is mainly security concerns, given the normal And abnormal operating conditions during the switching and control equipment used in SF6 for the object of the basic knowledge and guidance. These proposals should ensure that staff as SF6 for the object to secure minimum requirements. This standard applies to filled with switching and control equipment, industrial pure SF6 gas.2 Normative referencesThe following documents for the application of this document is essential.
