【摘要】 随着电力系统的不断发展,电网结构日益复杂,分布范围愈加宽广,维护的工作量和成本也越来越大。长期以来,变电设备检修一直是遵循着“到期必修、修必修好”的周期性检修制度。这种检修制度虽然有利于消除检修设备的隐含故障或缺陷,但并不是根据设备的实际情况来确定检修周期,对于运行状况良好的设备并不能有效地提高其设备运行率,会造成人力、物力的浪费,还有可能会把好的设备修坏。在这种情况下,需要有一种新的检修制度来改变目前的这种现状。因此状态检修应运而生。本文首先对目前继电保护设备的检修现状进行介绍,提出目前存在的问题;其次对在线监测技术的运用进行了深入的探讨,并结合实例分析了目前监测技术的不足和改进措施;再次,着重阐述了PMS系统中状态检修模块的应用情况,并在现有的备品备件管理模式的基础上,设计了一种能全面反应备品备件各种信息的智能化管理系统;最后根据实际的工作经验,结合各规程对继电保护状态检修在实际工作中的应用做了详细的介绍。

【Abstract】 With the development of the power system, the increasing complexity of the electric network structure and the expanding distribution range, the workload and the cost of maintenance are on the increase. Since a long time ago, the overhaul of the power transformer equipments has been following the periodic maintenance system, namely, examining the equipments when they become due and fixing them when they need to be fixed. This maintenance system is to the benefit of eliminating the possible breakdown or shortage of the equipments needed overhaul, but it isn’t determined according to their actual situation. As a result, those equipments in good condition are not able to improve operating ratios, which will lead to the waste of manpower and material resources. In addition, the good equipments may be botched up. Under this circumstance, a new maintenance system is needed to change the current status, so condition based maintenance emerges.First of all, this article introduces the current status of the maintenance of the relay protection equipments and puts forward the existing problems. Secondly, it discusses the application of the online motoring technology in depth. Thirdly, it emphasizes on the application of the condition based maintenance modules in the PMS system and it involves a computerizing management system which may reflect all the information of the standby redundancies based on the current management mode. Finally, according to the real work experience, it gives a detailed introduction of the practical application of the condition based maintenance of the relay protection combined with various regulations.
