电源SPD在线接地状态监测路径与方法的研究
|
摘要
本文通过对易燃易爆加油(气)站场所安装的电源SPD在线监测系统的接地状态的现行监测情况进行分析说明,首先介绍了利用电流通路法监测接地状态的监测方法,指出了其中的不足和优缺点,然后介绍了利用环路电阻法监测接地状态的监测方法,同样指出了此方法的不足和优缺点,最后结合接地电阻监测的仪器,构建一种新的监测思路,对同一仪器同时监测两个环路的监测数据值进行分析,以监测数值的突变和数据的变化率来判断接地状态的通断性,解决了易燃易爆场所电源SPD接地状态的监测准确性与价格昂贵的问题,确保易燃易爆场所电源SPD的监测安全问题,做到安全可靠,经济合理。
This paper analyzes the current monitoring situation of the grounding state of the SPD online monitoring system installed in the inflammable and explosive fueling(gas) station. Firstly, the monitoring method of monitoring the grounding state by current path method is introduced. The shortcomings, advantages and disadvantages are pointed out. Then the monitoring method of using the loop resistance method to monitor the grounding state is introduced, and the shortcomings, advantages and disadvantages of this method are also pointed out, and finally combined with the grounding resistance monitoring instrument, a new monitoring idea is constructed to analyze the monitoring data values of two loops simultaneously by the same instrument, monitor the change of the value and the rate of change of the data to judge the continuity of the grounding state, and solve the inflammable and explosive places. The monitoring accuracy and price of the SPD grounding state of the power supply ensure the safety of the SPD of the inflammable and explosive place, and it is safe, reliable and economical.
