摘要:
An apparatus for the generation, the distribution or the usage of electrical energy, the apparatus including a housing enclosing an insulating space and an electrical component arranged in the insulating space. The insulating space contains a dielectric insulation gas including an organofluorine compound A. The apparatus further includes a molecular sieve arranged such as to come into contact with the insulation gas. The molecular sieve has an average pore size y greater than the molecular size of at least one decomposition product of the organofluorine compound A generated during operation of the apparatus. The adsorption capability of the molecular sieve for organofluorine compound A is lower than for the at least one decomposition product. The apparatus further includes at least one desiccant arranged such as to come into contact with the insulation gas.

A circuit breaker including an ejection device with a compartment, in which an arc-extinction medium for improving circuit breaker operation is contained, and having an ejection orifice through which the arc-extinction medium is to be ejected, wherein the ejection orifice opens out into an injection zone of the circuit breaker in which the pressure is lower than in an arcing zone when an arc is present, and wherein the arc-extinction medium and/or exhaust-cooling medium is at least partially present in liquid form, when it is contained in the ejection device.

A circuit breaker including an ejection device including an arc-extinction medium for improved extinction of an arc formed during a breaker operation and an exhaust-cooling medium for improved cooling of exhaust gases in the circuit breaker. Thereby, the arc-extinction liquid includes an organofluorine compound having a boiling point Tb at 1 bar higher than −60° C. and being selected from the group of: a fluoroether; a fluoroamine; a fluoroketone; and mixtures thereof.
