Embodiment Construction

[0172] exist figure 1 The HV GIS shown in includes a circuit breaker 10 comprising two contacts 12a, 12b, one of which is movable relative to the other. One of the contacts 12a leads to a pair of bus bars 14, 14', and a first disconnect 16a, 16a' is arranged between the circuit breaker 10 and the corresponding bus bar 14, 14', respectively.

[0173] The other contact 12b leads to a bushing 18 which passes through a wall 20 of the building from the outside to the inside of the building. Between the circuit breaker 10 and the bushing 18, a second (output or feeder side) disconnector 16b with a snap action earthing switch 22 is arranged, with a potential transformer 24 and a current transformer 26 next to the second disconnector. device 16b arrangement.

[0174] The circuit breaker 10 is arranged in a circuit breaker housing 100 , the inside of which defines a circuit breaker insulating space compartment 102 . The circuit breaker insulating space compartment 102 contains the c...

Abstract

The invention relates to an electrical device (1) for producing, distributing and / or using electric energy. The electrical device (1) comprises a shell (2) sealing an electrical-device inside space (3). At least two insulated space compartments (102, 142, 162, 163, 182, 192 and 242) which are separated from one another and distributed continuously are formed by at least one portion of the electrical-device inside space (3). Electrical components (4; 10, 12a and 12b; 14 and 14'; 16a, 16a' and 16b; 184; 194; 22; 24) surrounded by insulating fluids are distributed in the insulated space compartments (102, 142, 162, 163, 182, 192 and 242) respectively. According to the electrical device, at least one of the first insulating fluid and the second insulating fluid comprises an organofluorine compound containing at least two carbon atoms, and the first insulating fluid is different from the second insulating fluid.

Description

technical field [0001] The present invention relates to electrical equipment for generating, distributing and / or using electrical energy, and further relates to the use of at least two different insulating fluids in a closed interior space of the electrical equipment, said inner spaces being formed apart from each other and arranged in a continuous manner At least two insulated space compartments. Background technique [0002] Dielectric insulating media in the liquid or gaseous state are traditionally used for the insulation of electrically conductive parts in various installations and in particular also in gas-insulated switchgear or components thereof. [0003] In medium-voltage or high-voltage metal-encapsulated switchgear, for example, the conductive parts are arranged in a gas-tight housing that defines an insulating space that contains an insulating gas and separates the housing from the conductive parts from the passage of current The insulating space. The insulati...
