山区高速公路在线监测系统的感应取电研究
|
摘要
针对目前山区高速公路在线监测系统存在供电难且电池更换不易的问题,对太阳能板供电、激光供电、感应取电三种供电方式进行分析、比较。讨论了高压线产生的交变磁场远近对感应取电的影响,研究了匝数、负载与启动电流之间的关系,对感应取电装置进行优化选择,并给出了电压和功率的计算方式。分析结果表明,以硅钢片为磁芯材料,线圈匝数在100匝左右时,能更加合理有效地利用输电线路的电磁能,为在线监控设备持续供电。
In view of the problem that the online monitoring system for expressway in mountain area is difficult in power supply and the battery is not easy to be replaced,the solar panel power supply,laser power supply and induction power supply were compared.The influence of alternating magnetic field produced by high voltage line on the induction power supply was discussed.The relationship between the number of turns,the load and the starting current was studied.The selection of the device was optimized,and the calculation method of voltage and power was given.The results show that with the silicon steel sheet as the core material,when the number of turns is around 100,the electromagnetic energy of the transmission line can be used more rationally and effectively,and the power supply for online monitoring equipment can be maintained.
