Abstract
An electrical energy transmission device for the transmission of electrical energy has a fluid-holding chamber. An electrically insulating fluid is contained in the fluid-holding chamber. The electrically insulating fluid is, at least in part, air-drawn from the surroundings of the electrical energy transmission device. The insulating fluid is used for insulating phase conductors in order to avoid short circuit conditions.
Claims13
An electrical energy transmission device, comprising:
- a maintenance unit configured for filtering atmospheric air which is drawn from surroundings of the electrical energy transmission device;
- a fluid-holding chamber for enclosing an electrically insulating fluid, the electrically insulating fluid being formed at least partially from filtered atmospheric air from the maintenance unit;
- and
- the electrically insulating fluid having the characteristics of having been filled into said fluid-holding chamber subsequent to an evacuation of said fluid-holding chamber.
A method of operating a life cycle management system for an electrically insulating fluid disposed in a fluid-holding chamber of an electrical energy transmission device for purposes of electrical insulation, which comprises the steps of:
- drawing in atmospheric air from surroundings;
- filtering the drawn in air in a maintenance unit of the electrical energy transmission device;
- evacuating the fluid-holding chamber;
- and
- subsequently introducing the filtered air into the fluid-holding chamber as an electrically insulating fluid.
