牵引降压供电所电气设备的预防性试验方法与重要性

Preventive Test Methods of Electrical Equipment of the Traction Step-down Power Substation and Its Importance

近年来我国高速铁路以及城市轨道交通快速发展,铁路电气化建设的不断完善,我国铁路电气化技术得到进一步提高。作为动力机车电力来源的牵引降压供电系统,其重要性不言而喻,对动力机车的动力性至关重要。我国的动力机车现在都是依靠电力进行牵引的,牵引电网与牵引降压供电系统的可靠运行有力的保障了动力机车运行的可靠和安全,因此对牵引降压变电所电气设备的预防性试验,可有效排除牵引降压供电过程中电气设备的故障,保证电气设备功能的正常,提高牵引降压变电所的供电效率。本文分析对牵引降压变电所电气设备进行预防性试验的重要性,重点分析变电所中变压器的预防性试验方法,以期为牵引降压变电所的变压器的预防性试验工作提供参考。

In recent years, the high speed railway and urban rail transit in China has rapid development, tile continuous improvement of the railway electrification construction has further improved the railway electrification technology in China. Traction step-down power supply system is the power source of power locomotive, it is very important for the dynamic performance of power locomotive. The power locomotives in China are rely on electricity for traction, the reliable operation of traction power grid and traction step-down power supply system effectively guarantees the reliable and safe power locomotive running. So the preventive test of the electrical equipment in traction step-down substation can effectively eliminates the fault of electrical equipment in the process of traction step-down power supply, guarantees the function of electrical equipment and improves the power efficiency of traction step-down substation. This paper analyzes the importance of the preventive test for the electrical equipment of traction step-down substation, mainly analyzes the preventive test method of transformer equipment to provide the reference for the preventive test work of the traction step-down substation transformer.
