Description

一种多电源供电回路检测方法、系统及装置 技术领域
本发明涉及轨道交通领域，特别涉及一种多电源供电回路检测方法、系统及装置。
背景技术
蓄电池电力工程车在直流接触网、第三轨或蓄电池三电源供电模式下，牵引主回路将不同电压等级(如DC1500V或者DC800V)的直流电通过高速断路器、斩波电抗器的滤波及牵引逆变器的逆变后，向后续三相交流异步牵引电机提供三相电压，满足工程车运行需求。三电源供电模式下的蓄电池电力工程车主回路示意图如图1所示。其中，接触网、第三轨及牵引蓄电池均属高压供电，为避免第三轨与接触网之间串电，目前的设计采用两种方案：一是使用接触器控制方式，即接触网和第三轨供电回路中各使用一个接触器，通过网络控制接触器的通断来达到隔离的目的。但是接触器的控制线圈功率较大，不能单纯的使用控制电源来启动，必须配备相应的继电器来带动其控制线圈。此方案需要考虑足够的安装空间，且控制逻辑也较为复杂。
二是在主回路中直接使用二极管隔离。此方案比较简单，不用考虑控逻辑的复杂性，仅通过二极管隔离，即可避免串电的风险。但是短时的高电压或者器件本身的质量问题，导致二极管被击穿，将使得接触网与第三轨之间的电路导通。此时若在库内升弓充电，车下的受流器也将带有高压电，存在人员触电的安全隐患。根据目前市场上已知成熟的二极管产品，其击穿后将导致电路短路，且无指示器，不能迅速发现击穿故障并作出相应处理。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据提供的附图获得其他的附图。
图1为现有技术中一种电力工程车的多电源供电回路示意图；
图2为本发明实施例中一种多电源供电回路检测方法的步骤流程图；
图3为本发明实施例中一种多电源供电回路检测系统的结构分布图；
图4为本发明实施例中一种多电源供电回路检测装置的结构分布图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例公开了一种多电源供电回路检测方法，应用于接触网和第三轨均通过隔离导通装置连接机车主传动系统的供电回路，参见图2所示，包括：
步骤S1：通过第一电压传感器获取备用供电回路的第一电压；
其中，当前机车主传动系统由目标供电回路供电，所述目标供电回路为接触网供电回路或第三轨供电回路，相应的，所述备用供电回路为处于备用状态的所述第三轨供电回路或所述接触网供电回路。
可以理解的是，目标供电回路在接触网供电回路和第三轨供电回路之间切换选择，选择后剩余的供电回路作为备用供电回路。
另外，所述多电源供电回路检测方法在步骤S1之后还可以包括：
通过第二电压传感器获取所述目标供电回路的第二电压；
判断所述第二电压是否处于预设范围；如果是，屏蔽所述第二电压；如果否，判定所述第二电压传感器故障。
这是由于目标供电回路的网压信号直接通过主传动系统的网压电压传感器即可获取，实际上与第二电压是等价的。之所以要获取第二电压，是为了验证第二电压传感器是否正常，如果获得第二电压的正常信号，也即，第二电压处于预设范围，那么第二电压传感器正常，无需再进行数据判断，直接在主传动系统的运行中使用网压信号即可；如果获得第二电压不在预设范围，那么判定第二电压传感器故障，无法发送正常信号。
步骤S2：当所述第一电压处于预设范围，判定所述备用供电回路与所述目标供电回路串电导通，并作出相应的故障处理。
具体的，不同的备用供电回路的故障处理步骤有略微不同：
当所述目标供电电路为所述接触网供电回路，判定所述备用供电回路与所述目标供电回路串电导通，断开所述机车主传动系统的高速断路器并进行降弓处理；
当所述目标供电电路为所述第三轨供电回路，判定所述备用供电回路与所述目标供 电回路串电导通，断开所述机车主传动系统的高速断路器并进行降靴处理。
进一步的，不论目标供电回路为接触网供电回路还是第三轨供电回路，
步骤S2均还可以包括：通过蜂鸣器和/或警示灯示警。
其中，具体还可以设置蜂鸣器和警示灯时的频率以及时长。
进一步的，本方法还可以包括记录各类信息，例如每次获取的第一电压、第二电压、当前的目标供电回路、故障信息和处理过程等，有利于之后的复查以及利用这些记录信息进行经验总结。
