作为我国铁路运输生产主型机车DF_4型内燃机车,近年来机车检修质量虽有了较大提高,但机车电气部分故障仍较频繁。减少机车电气部件的故障成为保证机车运用质量的重要环节。由齐齐哈尔科研所研制开发的BX—1型便携式内燃机车电气系统检测仪,是一种能在机车出入库或定修作业后快速检测多发性电气故障的便携式装置。该检测仪具有体积小、重量轻、操作简便等特点。上车只需将专用的夹子分别夹在所需测试的电气回路两端,就能够检测出电气回路中的电阻、接触电阻、蓄电池对地绝缘电
As China’s main railway locomotive DF_4 type diesel locomotive production, although the quality of locomotive maintenance over the past few years have greatly improved, but the locomotive electrical part of the fault is still frequent. Reduce the failure of locomotive electrical components to become an important part of ensuring the quality of locomotives. The BX-1 portable diesel locomotive electrical system tester, developed by Qiqihar Research Institute, is a portable device capable of rapidly detecting multiple electrical faults after a locomotive has been put in or out of operation. The detector has a small size, light weight, easy to operate and so on. On the train only need to clip the special clamps are required to test the electrical circuit at both ends, to be able to detect the electrical circuit resistance, contact resistance, battery insulation
