分布式母线保护子机检修方法和分布式母线保护系统
摘要：
本发明涉及分布式母线保护子机检修方法和分布式母线保护系统，分布式母线保护包括N个子机，N≥2，各子机之间通过通讯线路相互连接，每个子机均设置N个检修压板，当某一个子机检修时，检修子机投入所有检修压板，其他各子机投入检修子机对应的检修压板，然后对检修子机进行检修，不影响其他子机之间的信息交互，也不影响其他子机的正常运行，当检修完成后，各子机退出相应的检修压板。因此，通过在分布式母线保护子机中按子机个数设置检修压板以及检修压板的投入控制，不影响其他子机之间的信息交互，解决了分布式母线保护单个子机检修的问题。并且，该方法软件处理简单、可靠性高、易于实现，能够提高就地化母线保护装置的可靠性。
摘要（英）：

The invention relates to a distributed bus protection submachine maintenance method and a distributed bus protection system. The distributed bus protection system comprises N submachines, N>=2. The submachines are mutually connected through communication lines; each submachine is provided with N maintenance pressure plates; when some submachine is maintained, the maintenance submachine inputs allmaintenance pressure plates, and the other submachines input the maintenance pressure plates corresponding to the maintenance submachine, and then, maintenance is carried out on the maintenance submachine without influencing information interaction between other submachines nor influencing normal operation of the other submachines; and when maintenance is finished, each submachine quits the corresponding maintenance pressure plate. By setting the maintenance pressure plates and input control of the maintenance pressure plates according to the number of submachines in the bus protection sub-machines, information interaction between other submachines is not influenced, and the problem of maintenance of the single submachine of the distributed bus protection is solved. Besides, the method issimple in software processing, high in reliability and easy to realize, and can improve reliability of the on-site bus protection device.
