Circuit breaker is housed a gas-blast relates to a device has the main contacts improved

摘要

P the invention relates to a device of the drawings of the main contacts cells, in a sealed casing filled with insulating gas sf6. / p & & p & the terminals of the current people brought 20, 22 form the nodes of the derivation of the main circuit 14 and the auxiliary circuit 16 shifted transversely from one another at the interior of the envelope 10. A shunt resistor 54 is arranged in the auxiliary circuit 16 between the rod 46 and the terminal 22 lower. An intermediate wall 56 of insulating material divides the internal space of the envelope 10 into two compartments 60, 62 bunk, one of which 60 contains the main contacts 24, 38 and the other 62 the breaking gap 64. / p & & p & application: a gas-blast circuit breaker. / p
