Description
技术领域：Technical field:
本发明涉及一种地铁列车减震发电技术，特别是一种共振储能机电转换城市地铁列车减震发电装置，该装置通过共振储能机电转换将城市地铁列车运行中的震动动能转换为电能，为城市地铁列车车箱内照明提供电能，可降低城市地铁列车运营成本，节能环保。 The invention relates to a subway train shock absorption power generation technology, in particular to a resonance energy storage electromechanical conversion urban subway train shock absorption power generation device. Provide electric energy for the lighting in the compartment of urban subway trains, which can reduce the operating cost of urban subway trains, save energy and protect the environment.
背景技术：Background technique:
城市地铁是城市交通中重要的基础设施，是社会经济正常运行的必要基础，是缓解交通拥堵、满足社会经济发展和居民出行需求的重要手段。 Urban subway is an important infrastructure in urban transportation, a necessary basis for the normal operation of the social economy, and an important means to alleviate traffic congestion and meet the needs of social and economic development and residents' travel.
随着国民经济的快速发展以及城市居民出行需求的日益增长，各大城市都加快了公共交通的发展速度。但是由于地铁运量大，其耗电总量十分巨大，并且电力是地铁消耗的最主要能源，地铁供电通常来自城市电网，通过地铁供电系统实现变换和传输。其电力能耗主要分为列车运行牵引电能和车厢照明设备所消耗的电能两部分。 With the rapid development of the national economy and the increasing travel needs of urban residents, major cities have accelerated the development of public transportation. However, due to the large transportation volume of the subway, its total power consumption is very huge, and electricity is the most important energy consumed by the subway. The power supply of the subway usually comes from the urban power grid, which is converted and transmitted through the subway power supply system. Its power consumption is mainly divided into two parts: the traction power of the train running and the power consumed by the compartment lighting equipment.
在当前我国建设节约型社会的大背景下，如何建设节能型轨道交通系统已经成为轨道交通系统规划设计与建设管理中的一个重要研究课题。也是行业发展的方向和追求的目标。 Under the background of building a conservation-oriented society in our country, how to build an energy-saving rail transit system has become an important research topic in the planning, design and construction management of rail transit systems. It is also the direction and goal of the industry's development.
由于城市地铁是在地下运行，车厢的照明设备需要24小时不间断供电，如果能将地铁列车运行中多余的动能转换为电能，为车厢的照明设备提供电能，将为国家节约大量的电能，即节能环保，又可降低城市地铁运营成本。 Since the urban subway is running underground, the lighting equipment in the carriage needs 24-hour uninterrupted power supply. If the excess kinetic energy in the operation of the subway train can be converted into electric energy to provide electric energy for the lighting equipment in the carriage, it will save a lot of electricity for the country, namely Energy saving and environmental protection can also reduce the operating cost of urban subways.
