SF6 electrical circuit breaker is a device where a current operates with SF6 or Sulphur Hexafluoride being carried on its contacts. Testing services for SF6 breakers ensure that these devices break off the power when there's an excessive electricity supply that exceeds the allowed voltage to prevent circuit overload.
SF6 gas circuit breakers are H.V.A.C. porcelain type circuit breakers filled with SF6 gas. They are available with voltage from 40.5-550kV and rated current up to 4000A. Our company manufactures these circuit breakers with three types of operating mechanisms: pneumatic, spring, and hydraulic.
In 1957, the puffer-type technique was introduced for SF6 circuit breakers, wherein the relative movement of a piston and a cylinder linked to the moving part is used to generate the pressure rise necessary to blast the arc via a nozzle made of insulating material (Figure 1).
It is now possible to use low energy spring-loaded mechanisms to drive high-voltage circuit-breakers up to 800 kV. The first patents on the use of SF6 as an interrupting medium were filed in Germany in 1938 by Vitaly Grosse (AEG) and independently later in the United States in July 1951 by H. J. Lingal, T. E. Browne and A. P. Storm (Westinghouse).
