Detailed description of the invention
For making the purpose of the present invention, technical scheme and advantage clearer, develop simultaneously referring to the drawings Going out preferred embodiment, the present invention is described in more detail.However, it is necessary to explanation, in description The many details listed be only used to make reader one or more aspects of the present invention are had one thorough Understand, the aspects of the invention can also be realized even without these specific details.
The present inventor is it is considered that the isolation in railway operation place can be replaced by intelligent breaker Switch;And row ripple harvester is set at the two ends of each contact net, to monitor the power information of contact net; When the master controller arranged judges contact net fault according to the power information monitored, control to connect with this The intelligent breaker of net-fault electric connection disconnects, so that judging the timely power-off of out of order contact net;And Intelligent breaker position is set close to contact net, the power supply in traction substation is farther out;Can in case The only power overload situation in traction substation, it is to avoid the feeder switch tripping operation in traction substation, short circuit;This Time so that other feeder line keep normal power supply;Have a power failure such that it is able to reduce because of contact net power failure Scope.
Introduce two embodiments of technical scheme below in conjunction with the accompanying drawings.
Embodiment one
In the embodiment of the present invention one, Intelligent Selection based on contact net jumps the framework signal of the electric power system of device Figure, as in figure 2 it is shown, include: traction substation 201, multiple contact net bundle, the Intelligent Selection of contact net bundle Jump device 203.Wherein, a contact net bundle is made up of a plurality of contact net 202.Traction substation 201 He Multiple contact net bundles is all located in railway operation place.
Power supply (not marking in figure) in traction substation 201 passes through multiple feeder switches (not marking in figure) Export multiple feeder line 211 for power supply respectively;For each feeder line 211, this feeder line 211 is via intelligence Choosing is jumped device 203 and is powered at least one contact net bundle;One contact net bundle is by 202 groups of a plurality of contact net Become.Contact net 202 can be specifically contact cable.
The block schematic illustration of the structure of Intelligent Selection jumping device 203, as shown in Figure 3 a, including: master controller 301, and the Intelligent Selection mode hopping block being respectively provided with for each contact net bundle.
