对电容器的内外部故障及对应的保护方式进行了分析,明确了现行电容器保护的整定原则,从一、二次设备协调一致的角度对电容器不平衡型继电保护进行了分析比较,给出了该类保护的选型技术原则。文章分别以CH4,CO2及He为吸附气体,进行了相同实验条件下煤的三轴渗流实验,分析和探讨了上述气体对煤的渗透率的影响规律,实验结果对研究煤矿瓦斯抽放与瓦斯突出具有一定的现实意义。
The internal and external fault of the capacitor and the corresponding protection methods are analyzed. The current setting principle of capacitor protection is clarified. The unbalanced protection of capacitor is analyzed and compared from the perspective of the coordinated primary and secondary equipment. The protection of the selection of technical principles. In this paper, the triaxial seepage experiments of coal under the same experimental conditions were carried out using CH4, CO2 and He as adsorption gases respectively. The influence laws of the above gases on the permeability of coal were analyzed and discussed. The experimental results are very helpful for the study on gas drainage and gas Prominent has a certain practical significance.
