SGE-MT Series handheld SF6 gas density calibrating instrument

Description:

SF6 electrical products has been widely used in electric power department industrial and mining enterprises, which promote the rapid development of the electric power industry. How to guarantee the operation reliability and safety of SF6 electrical products has become one of the important tasks of power sector. SF6 gas density relay is one of the key components of SF6 electrical switch. It can detect change in density of SF6 gas in electrical equipment. Its performance directly affects the reliable and safe operation of the SF6 electrical equipment.
After the installation of SF6 gas density relay in field, since the lack of movement, phenomenon happen like action not flexible or touch point contact undesirable. In some cases, the temperature compensation performance will become worse. The SF5gas density relay will easily mis-operate when the ambient temperature change. Therefore, DL/T596 is formulated by the original power department 1996 regulations of “power equipment preventive test” and “25 key requirements to prevent power production major accident of”, the test procedures and requirements stipulate that units who use SF6 electrical switch should arrange regularly check of SF6 gas density relay. Seeing from the actual operation, the regularly check on SF6 gas density relay is one of the necessary measures to prevent accidents and guarantee the safety and reliability operation.
