综合接地系统在无碴轨道施工中的应用分析

Analysis of the application about integrated grounding system on ballstless track

随着时速350 km/h无碴轨道在武广客运专线的运用,为保证供电系统、通信系统、轨道系统等的安全、可靠和稳定,针对其轨道电路的传输特点和需要,在借鉴普通铁路和地铁接地技术的基础上,经过理论分析实验,在武广客运专线采用了电气化、电力、通信、信号、轨道等系统的综合接地技术。通过实际检测和后期运营的验证,综合接地系统能够确保各系统的正常运行,综合接地技术在无碴轨道中得到了成功应用。本文简述了综合接地技术应用在无碴轨道中的必要性和具体措施,为客运专线无碴轨道综合接地的实际施工提供依据。

With the application of ballastless tracks with a speed of 350 km/h,Wuhan-Guangzhou passenger line,through theoretical analysis and experiments based on reference to common rail and subway grounding technology,has adopted integrated grounding technology such as electrification,electricity,communication,signal,track,and so on.According to the transmission characteristics and the needs of the track ciruit,all these are aiming to guarantee the safety,reliability,stability of the power supply system,communication system and track system.The actual monitoring and the post-operational validation prove that the integrated grounding technology can ensure the normal operation of the whole system.The necessity of its application was described in ballastless tracks and the specific measures,which can provide a reference for the actual integrated grounding construction of ballastless tracks in passanger line.
