随着列车的不断提速,铁道部、铁路局先后进行了信号设备维修制度改革,要求对信号设备实行“多巡、多测、少动、合理检修”。我局从2000年1月开始对信号设备实行了“天窗修”和集中修。在维修体制改革和列车提速的推动下,信号设备要点相对困难,车站给点次数也大幅度减少。为了保证列车提速的安全,对电动道岔的动作电流、摩擦电流要加强测试,以便及时掌握道岔运用质量。因此,对控制台现有电流表的更新十分必要。一、研制控制台钳位直流电流表的原因:
With the continuous speeding up of trains, the Ministry of Railways and the Railway Administration successively carried out the reform of the signal equipment maintenance system and required the implementation of “multi-tour, multi-test, less-moving and reasonable maintenance” of the signal equipment. Our bureau from January 2000 on the implementation of the signal equipment “skylight repair ” and focus on repair. Under the impetus of the maintenance system reform and the train speed increase, the signaling equipment points are relatively difficult, and the number of points to the station is also greatly reduced. In order to ensure the safety of train speeding, the operating current and triboelectric current of the electric turnout should be strengthened in order to grasp the quality of the turnout in time. Therefore, updates to the console’s existing ammeter are necessary. First, the development of the console clamp DC ammeter reasons:
