Technical field
The present invention relates to for generation of, distribute and/or use the electric equipment of electric energy, and further relate to and in the closed interior space of electric equipment, use at least two kinds of different dielectric fluids, described inner space forms at least two insulating space compartments spaced and that arrange in a continuous manner.
Background technology
Dielectric insulation medium in liquid state or gaseous state be applied to traditionally in various device and special also for the insulation of the conductive component of gas isolated switchgear or its parts.
In the switchgear of middle voltage or high-voltage metal encapsulation, for example, conductive component is arranged in the airtight housing that limits insulating space, and described insulating space comprises insulating gas and by housing and conductive component separates and do not allow electric current pass through this insulating space.In order to interrupt for example electric current in high-voltage switch equipment, this dielectric also plays the function of arc extinguishing medium (or arc-extinguishing medium).
In the switchgear of conventional gas insulation, sulphur hexafluoride (SF
6) be typically used separately as dielectric and/or arc-extinguishing medium.
Recently, proposed to use organofluorine compound as the substitute of the conventional dielectric such as air in dielectric.
Specifically, WO-A-2010/142346 discloses the dielectric insulation medium that comprises the fluorinated ketones contained that contains 4-12 carbon atom.In addition, WO-A-2012/080246 discloses the particularly preferred C5K that is mixed with the dielectric insulation gas component that is different from the fluorinated ketones contained (being called for short hereinafter " C5K ") that contains definitely 5 carbon atoms.
Shown that disclosed fluorinated ketones contained has high rupturing capacity in WO-A-2010/142346 and WO-A-2012/080246, there is especially high dielectric strength and high extinguishing arc ability.Meanwhile, they have extremely low global warming potential (GWP) and extremely low toxicity.
Although for example contain the insulating gas of fluorinated ketones contained, have above-mentioned excellent properties, have been surprisingly found that the composition in current interruptions aspect of performance the best might not produce best dielectric insulation performance, vice versa.
And organofluorine compound can produce the problem about the compatibility of the concrete material component with electric equipment, although the material of they and other members is completely compatible.While using dielectric in the electric equipment that is arranged in a plurality of different electric members in independent continuous cavity in combination (as the situation of for example switchgear), this is correlated with especially, because for a concrete electric member or chamber, the optimal selection of dielectric may not necessarily be suitable for the optimal selection for another electric member or chamber.
Consider above-mentioned factor, the problem being solved by the present invention is to provide the electric equipment that comprises at least two electric members in the compartment that is arranged in continuous separating (particularly mutually not leakage current body or airtight), increases thus described electric equipment for the combination property of insulation and/or extinguishing arc.
