Embodiment Construction

[0033] figure 1 shows a track construction machine 1 for working on a track installation, in particular for consolidating a ballast bed 2 of the track installation. The track installation comprises two rails 3 which rest on a ballast bed 2 via sleepers 4 . The track installation also has an overhead line 5 for supplying the track construction machine 1 with electrical power. The overhead line voltage provided at the overhead line 5 is 15 kV, and the overhead line frequency is 162 / 3 Hz. The track construction machine 1 is electrically conductively connected to the overhead line 5 via a pantograph 6 .

[0034] The track construction machine 1 includes a rail car 7 for traveling on a rail 3 . The rail vehicle 7 has a drive motor 8 for displacing the track construction machine 1 on the rail 3 . The drive motor 8 is connected in a torque-transmitting manner to the running wheels 9 of the rail vehicle 7 .

[0035] The track construction machine 1 has a railway converter 10 for ...

Abstract

The invention relates to an interface device (16) for supplying several consumers (17, 18, 19) with electric power from a converter (10) of a track construction machine (1), which comprises a connection means (24) for electrically connecting to a direct voltage circuit (14) of the converter (10) and a distributor device (23) electrically connected to the connection means (24) for connecting the plurality of consumers (17, 18, 19).

Description

technical field [0001] The invention relates to an interface device for supplying electrical power from a railway converter of a track construction machine to a plurality of electrical consumers. The invention also relates to a track construction system comprising such an interface device. The invention also relates to a track construction machine with such a track construction system. Background technique [0002] A track construction machine is known from existing public use having a rail car for traveling on the rails, a rail converter for supplying electricity and a plurality of power consumers for working on the track installation equipment. In order to supply electrical consumers with electric power, these consumers are connected to the AC voltage circuit of the railway converter. With railway converters, the overhead line voltage is first converted to a DC voltage and then to a lower voltage for application to AC voltage circuits. Disadvantageously, during the con...
