The utility model relates to a portable electric testing instrument for diesel locomotives, which belongs to the technical field of electrical maintenance instruments and is used for testing electric appliances for diesel locomotives. The technical scheme is that the electrical detection part is composed of contactor, two color LED lights, current limiting resistance, fuse, wire clamp and wire. Two color LED lights form a parallel circuit. One end of the parallel circuit is connected with the contactor, the other end of the parallel circuit is connected with the current limiting resistance, the current limiting resistance is connected with wire clamp through the fuse, and the polarity phase of the two color LED parallel connection. On the contrary, the colours are different. The utility model has the advantages of simple structure, low cost, convenient operation, reliable performance and easy implementation, can quickly detect the on-off and polarity of the circuit under test, and can also reduce the current intensity of the coil of the contactor under test, so as to control the electric apparatus not to produce action, thus effectively avoiding the electrical malfunction caused by the circuit testing process and ensuring the safety and stability of the locomotive equipment. \u3002
【技术实现步骤摘要】
一种便携式内燃机车电器检测仪
本技术涉及一种便携式内燃机车多功能电器检测仪,属于电器维修仪器
技术介绍
目前,机车检修体制采用的是专业化集中修、部件互换制、机械化自动化修理流水线以及故障诊断等技术,因此修车的质量与效率大大的提高、在修周期大幅度缩短、修车费用不断下降、运行可靠性日趋提高、检修间隔周期逐渐延长。随着电传动车组、电力机车的广泛应用,机车检修检测设备的研制与应用也随之快速发展。现代机车电器装置复杂,机车电路中电器联锁节点很多,试灯作为检测判断机车电器故障的工具也不断更新换代。最初的试灯是由导线、线夹、灯泡组成,后来演变为插针式试灯,现在又出现了电笔式试灯,其原理基本一致,都是利用两个试灯连接所测试线路,闭合蓄电池闸刀后,根据两试灯显示情况来判断电路通断。但是现有试灯有个最大缺陷,既使用试灯进行接地检测时,试灯正端与接触器线圈前方电路接触,接触器线圈会得电,造成电器误动作,也就为机车运行埋下安全隐患。
