Abstract

The invention discloses a locomotive electrical fault diagnosis device comprising multiple independent unit circuits, and positive connecting terminals (6) and a negative connecting terminal (9) which are connected with each unit circuit. Each unit circuit comprises current-limiting resistors (5) and indicating lamps (3) which are connected in series with the current-limiting resistors (5). The diagnosis device is connected in parallel with a locomotive circuit via the positive connecting terminals (6) and the negative connecting terminal (9) According to the diagnosis device, problems that locomotive electrical fault points are not easy to search can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of locomotive fault diagnosis, in particular to a diagnostic device for electric faults of locomotives. Background technique [0002] The locomotive may have mechanical failure or electrical failure, and the electrical failure of the locomotive mainly includes the failure of various control electrical appliances and circuits. Such as railway diesel locomotives, according to statistics, electrical failures account for nearly 60% of the total number of railway locomotive failures, and timely handling of electrical failures is the key to ensuring the normal operation of locomotives; more than 50% of railway locomotives have electrical failures, and correct handling by the locomotive crew on duty can Eliminate, or enable the locomotive to maintain operation until returning to the section for maintenance, avoid rescue, save costs and impact; the biggest feature of electrical faults on diesel locomotives is that t...
