Description
Technical field
The utility model relates to power supply, especially a kind of highway advices plate remote electric power system.Be applicable to highway and longlyer need draw the powerful devices such as remote advices plate.
Background technology
In the supervisory control system of highway, is furnished with variable information board at different sections of highway place as required, to provide the information of high-grade highway as the situation of the vehicle flowrate on whole piece circuit, weather conditions, black spot.And the power supply of current advices plate, what generally adopt is the form of being powered to remote advices plate equipment by the power cable laid from the electric substation's AC power set by highway.As shown in Figure 1, in this scenario, equipment is powered to adopt and is exchanged remote power feeding form, the AC energy being positioned at communication power supply room or electric substation by power cable long-distance transmissions to complete monitoring equipment use, due to distance, line drop is large, and therefore also needing on the line increases necessary stabilized voltage power supply.And due to adopt be the mode that AC power is powered to apparatus remote by cable, if use the original pipeline parallel with telecommunication cable, due to long transmission distance, interference certainly will be brought to communication, therefore, highway both sides ditching laying form is separately changed in the laying of power cable, causes the increase of construction cost, meanwhile, inevitably cause cable easily stolen.
Patent (patent No.: ZL 200520101873.8) proposes a kind of DC remote power supply powering mode, for in highway long distance control system, the equipment of less electric power is powered and is provided a kind of well solution, but in actual use, run into larger electric power, need the equipment that zooms out of longer distance to power, only have 400-450V because the remote power feeding system feed voltage adopted at present is the highest, need to adopt larger cross-section (10mm
2and more than) cable could stable power-supplying, cable still needs ditching separately to lay.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of very high pressure remote electric power system aiming at the remote power-feeding of highway high-power advices plate system.Be intended to solve highway needs remote ditching cable laying difficulty because distance is far away, for highway high-power advices plate system provides the powering solution that a kind of reliability is high, be easy to implement.
The utility model is achieved through the following technical solutions: a kind of highway advices plate remote electric power system, be made up of remote power feeding transmitting portion, remote power feeding receiving unit, cable transmission line, described remote power feeding transmitting portion contains AC/DC or DC/DC converter, its DC power supply produced is transferred to remote power feeding receiving unit through cable transmission line, containing DC/AC or DC/DC converter in described remote power feeding receiving unit, described DC/AC or DC/DC converter is connected with corresponding advices plate equipment.
Further, the voltage that AC/DC or the DC/DC converter in described remote power feeding transmitting portion exports is 500-900V direct current very high pressure.
Further, DC/AC or the DC/DC converter contained in described remote power feeding receiving unit, its input allows normal maximum operating voltage to reach 900V.
Further, the cable cross-sections of described cable transmission line is long-pending is not more than 6mm
2, lay in expressway communication pipeline.
Compared with prior art, the beneficial effects of the utility model are: the utility model is owing to adopting very high pressure direct current transportation form, and the cross-section of cable of electric energy transmitting is long-pending can be less than or equal to 6mm
2can be laid immediately in the original communication pipe of highway, avoid the necessity excavated raceway groove separately and carry out laying, solve the difficulty that the relatively high power equipment such as highway advices plate need grow distance ditching laying, for system cloud gray model provides the method for supplying power to that a kind of reliability is high, be easy to implement, equipment is run more reliable, maintenance workload reduces, greatly can reduce construction and input cost simultaneously, lower the stolen risk of cable.Meanwhile, owing to adopting very high pressure direct current transportation form, when avoiding the power transmission mode in the past adopting AC power to be powered to apparatus remote by cable, the problem that signal of communication is disturbed.
Accompanying drawing explanation
To be prior art to power catenation principle figure to advices plate equipment Fig. 1;
Fig. 2 is that the utility model supplies the schematic diagram of electrical connection to advices plate equipment.
Wherein: 1, remote power feeding transmitting portion; 2, remote power feeding receiving unit; 3, cable transmission line; 1-1, AC/DC or DC/DC converter; 2-1, DC/AC or DC/DC converter; 2-2, advices plate equipment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 2, the utility model relates to a kind of highway advices plate remote electric power system, by remote power feeding transmitting portion 1, remote power feeding receiving unit 2, cable transmission line 3 forms, described remote power feeding transmitting portion 1 is containing AC/DC or DC/DC converter 1-1, its DC power supply produced is transferred to remote power feeding receiving unit 2 through cable transmission line 3, containing DC/AC or DC/DC converter 2-1 in described remote power feeding receiving unit 2, described DC/AC or DC/DC converter 2-1 is connected with corresponding advices plate equipment 2-2, the voltage that AC/DC or DC/DC converter 1-1 in described remote power feeding transmitting portion 1 exports is 500-900V direct current very high pressure, DC/AC or the DC/DC converter 2-1 contained in described remote power feeding receiving unit 2, its input allows normal maximum operating voltage to reach 900V, the cable cross-sections of described cable transmission line 3 is long-pending is not more than 6mm
