The improvement of bus charging protection device of xisaishan power plant was introduced , which solved the problem that the charging protection can not switch quickly , so it improved its reliability and service life , reduced the operation procedures of the operators 摘要介绍了对西塞山发电厂母线充电保护装置的改进，解决了充电保护的动作时间不能快速切换的问题，提高了保护装置的可靠性和使用寿命，减少了运行人员的操作程序。
There are no more descriptions to the arithmetic itself , because it is enough to use in engineering . it is the dynamic time property that is figured out so as to provides parameters for engineering design lately , compared with actual value , and analyzed the factors of influencing pilot valve 由于该方法在工程应用上较为成熟，对算法本身没有作过多的论述，着重计算了本机构的动作时间，并与实际运动时间作了比较，同时分析了影响一级阀动作时间的因素，为以后的工程设计提供一个结构数据的参考意见。
20 . electric system fig . 10 a . the plc controlled electric system and diagrammatic operation system make the order of all mechanical operations and the adjustment of operation time expressed in letters or figures on the screen which makes the operation and adjustment more convenient and steady 20 .电控系统fig10 a电控系统采plc控制，搭配图形荧幕显示操作系统，本机所有动作功能的选用及所有动作时间的调整，均于荧幕上以图形及数字显示，大幅提升操作及调整的方便与稳定性。
The system solves the problem that one device can control many parameters testing . it can complete auto - test and auto - data - collection of acting time difference between the 8 contract resistances and 6 switches without debugging the power by hand . serial communication program can automatically transmit the testing data and information to the upper computer after the data testing 机车电器测试系统解决了一台装置进行多项参数测试的计算机控制问题，能进行8路接触电阻、 6路开关的动作时间的自动测试、通道的自动切换及数据采集；并无须人工调试电源；串口通信程序在测试完毕后自动向上级计算机传输测试数据和信息交换。
