FGB1 -12/24/40.5 series indoor type SF6 circuit breaker, its used for controlling and protecting transmission and distribution systems of power plants and transformer substation, electric equipment and electric line, especially in the case of frequently operating position, it not only use in new transformer substation construction, but also suit free oil reconstruction of old transformer substation.
++++Feature
Adopt compact design schema with light & small volume;
High reliable type spring mechanism;
Provide a high table and advanced grade products;
Achieve free maintenance,long life requirement;
a widely available gas sealed pressure system
Like all gases in current use, SF6 is available in all countries of the world.SF6 is non-toxic.All Merlin Gerin switchgear is of the sealed pressure system type in accordance with the IEC 56 definition (appendix EE).Enclosures are filled to a low relative pressure of 0.05 to 0.35 MPa (0.5 to 3.5 bars).
a non-inflammable gas
SF6 is an inert gas and does not sustain combustio n. The seal and the for-life lubrication of the rotary seals is provided by an oil film.In the MV circuit breaker field, for example,on more than 20 000 SF6 switchgear units installed by the French electrical utility (EDF), the annual fault rate related to seal problems is less than 0.05 %
A very stable gas
The high stability of SF6 gas is due to the 6 covalent bonds of its molecule.
an insulating gas
The dielectric strength of SF6 is superior to that of most know n media, reaching 5 times that of air at a pressure of a few tenths of Mpa.
a breaking gas
SF6 is "the" breaking gas offering a number of advantages:high capacity for arrying the hea t produ ced by th e arc. The arc is rapidly cooled by convection during arcing; high radial thermal conduction and high electron capturing capacit y;when the current passes through zero:5 the SF6 permits rapid heat exchange from the cent re of the a rc towa rds the exterior,5 the fluorine atoms, which are highly electro-negative, act as veritable "traps" for electrons; since it is the electrons which are mainly responsible for electric conduction in the gas, the gap between the contacts recovers its initial dielectric strength through this electron capture phenomenon at current zero.
very low maintenance
The electrical contacts, housed in a sealedfor-life enclosure,require no specialmaintenance.The operating mechanism requires only minimum maintenance at intervals depending on the conditions of use.Under normal operating conditions, no
preventive maintenance is required before 10 000 operations or 10 years of service
