在对国电成都热电厂嘉陵2×142MW机组两炉一机单元给水系统控制方式进行分析的基础上，针对运行中出现的汽动给水泵不能直接调节单台锅炉汽包水位及给水母管压力超限等问题，利用分散控制系统信息共享、组态功能强大、修改方便的特点，在不增加硬件设备的情况下，通过软件组态增加了汽动给水泵调节单台锅炉汽包水位调节回路和给水母管超压及欠压保护回路，实现了机组在一炉一机单元运行和两炉一机母管运行2种运行方式下给水自动的合理控制，并解决了给水母管的压力保护问题，提高了机组运行的安全可靠性。

Basing on TI Corporation's DSP chips TMS320LF2407A as high-voltage protection system CPU in this article, AC analog which comes from high voltage power grid is converted to digital value which DSP can process by 14-bit A/D converter MAX125, monitoring the entire status of the high-voltage power grid in real-time, tripping off by controlling external relay quickly when abnormal operation happened, turn off the power grid to protect the power grid and other electrical equipment.

本文是基于TI公司的TMS320LF2407A型DSP芯片作为高压电继电保护系统的中央处理器。通过MAX125的14位A/D转换器采集高压电网中交流模拟量来转换为供DSP处理的数字量，从而进行数据分析处理，对整个高压电网的运行状况进行实时监控，当遇到不良运转时控制外部继电器迅速跳闸，切断电网，从而保护整个电网及其他用电设备。

在装有安全气囊系统的容器外部都印有Supplemental Inflatable Restraint System，简称SRS的字样，直译成中文，应为&辅助可充气约束系统&。英文名称中强调了安全气囊是辅助性的设备，应该与安全带配合工作才能起到最佳的保护作用。可惜的是中文名称中忽略了这一点，容易给用户带来误解，以为仅靠安全气囊就能获得良好的保护效果。其实，若不配合安全带使用的话，在某些情况下，安全气囊展开时会对乘员造成不必要的伤害。
