Pantograph carbon strip wear detection system

大多数电动列车都装有受电弓，将电力从架空线路传输到机车。受电弓经常与架空线路接触。导角装有碳接触条，碳接触条是消耗品的牺牲部件。受电弓碳接触条磨损对架空线路造成的损坏可能会导致灾难性的故障，从而导致断线，造成数百万英镑的损失和服务中断。目前还没有已知的方法可以实时检测碳带的磨损，因此，碳带是定期更换的，通常过早，造成不必要的费用，增加了维护时间和成本。有静态系统在给定的时间点和地点捕获和分析受电弓碳磨损，它们只提供集电极条状况的快照。JR Dynamics LTD （JRD）开发了一种概念系统，可以准确检测碳磨损，从而减少维护成本和时间。JRD的愿景是为所有受电弓配备低成本的碳条磨损监测系统（CWD），向列车操作员实时传达磨损状态，从而避免过早更换和不必要的更换。目标是创建一个智能的低成本系统，提供和改造现有的受电弓，几乎没有中断或成本。收入将通过提供/集成损耗监测技术，通过数据采集和分析作为维护优化的一部分，其中数据访问是收费的。这些模式已由JRD通过提供PANDAS而付诸实践；受电弓冲击检测系统，因此这种收费模式已经被列车运营商所接受。该项目将专注于创建一种CWD，该CWD将与现有的受电弓集成，最大限度地减少修改和中断，同时满足立法和铁路法规，以确保产品被铁路当局接受和批准。创新将是模块化碳带和碳带磨损检测基地的生产，该基地将包含必要的传感器和远程信息处理。

The majority of electric trains are fitted with a pantograph that transmits power from overhead lines to the locomotive. The pantograph is in constant contact with the overhead lines. The guide horns are fitted with a carbon contact strip which is a sacrificial component that is a consumable. Damage to overhead lines due to worn pantograph carbon contact strips can cause catastrophic failures that can lead to de-wirements, costing milions of pounds and service disruptions.Currently there are no known methods for detecting the wear on the carbon strip on a "real time" basis and as such, the carbon strip is replaced on periodic bases, often prematurely, causing unnecessary expense, added maintenance time and cost. There are static systems which capture and analyse pantograph carbon wear at a given point and place in time, they do not provide anything more than a snapshot in time of the condition of the collector strips. JR Dynamics LTD (JRD) developed a concept for a system that would accurately detect the carbon wear and thus reduce maintenance costs and times.JRD's vision is to equip all pantographs with a low cost carbon strip wear monitoring system (CWD) that conveys to the train operator the state of wear in real time and thus avoiding premature replacement and unnecessary changeovers.The objective is to create an intelligent low cost system that is supplied and retrofitted to existing pantographs with little disruption or costs.Revenue will be through the supply/integration of the sacrificial wear monitor technology, through to data capture and analysis as part of maintenance optimisation where the access to the data is chargeable. Such models have already been put in practice by JRD through the supply of the PANDAS; pantograph impact detection system and thus this model of charging has already been accepted by train operators.The project will focus on created a CWD that integrates with existing pantographs with minimal modifications and disruptions while meeting legislation and rail regulations to ensure that the product is accepted and approved by the rail authority.The innovation will be the production of a modular carbon strip and a carbon strip wear detection base that will contain the necessary sensors and telematics.
