Abstract
A power transmission system facilitates the location of an insulation fault in the power transmission system by providing a power transmission network, an insulation fault locating unit and a connecting line system which is electrically connected to the insulation fault locating unit and to the power transmission network. The connecting line system includes a switch constructed to interrupt and re-establish an electrical connection between the power transmission network and the insulation fault locating unit. A vehicle, in particular a rail vehicle, including a power transmission system and a method for operating a power transmission system, are also provided.
Claims15
A power transmission system, comprising:
- a power transmission network;
- an insulation fault detection unit;
- an insulation fault locating unit;
- and
- a connecting line system electrically connected to said power transmission network, said connecting line system including a changeover switch constructed to break an electrical connection between said insulation fault detection unit and said power transmission network and, simultaneously, to electrically connect said insulation fault locating unit to the power transmission network.
A power transmission system, comprising:
- a power transmission network;
- an insulation fault locating unit;
- a connecting line system being electrically connected to said insulation fault locating unit and to said power transmission network, said connecting line system including a switch constructed to break and re-establish an electrical connection between said power transmission network and said insulation fault locating unit;
- a data bus;
- said power transmission network including a plurality of branch circuits;
- said insulation fault locating unit including an evaluation device, a plurality of measuring instruments each being associated with a respective one of said branch circuits and a plurality of instrument transformers each being electrically connected to a respective one of said measuring instruments;
- said instrument transformers each being disposed on a respective one of said branch circuits;
- and
- a plurality of said measuring instruments being connected to said evaluation device by said data bus.
A method for operating a power transmission system, the method comprising the following steps:
- selectively electrically connecting a connecting line system between a power transmission network and an insulation fault detection unit or an insulation fault locating unit via a changeover switch ;
- and
- upon occurrence of a predefined condition, using the changeover switch of the connecting line system to break an electrical connection between the insulation fault detection unit and the power transmission network and, simultaneously, to electrically connect the insulation fault locating unit to the power transmission network.
