摘要

摘要本文描述了一种评估机械摩擦火花静电性能的尝试。这种火花是造成硬煤矿许多事故的原因。文章对近年来波兰硬煤开采事故进行了总结。在大多数情况下,首字母都是机械火花。机械火花含有能量,其中一部分与它们多余的静电荷有关,而另一部分则来自不同的来源(例如动能或热能)。本文试图估计这些能量中有多少是由静电冲击产生的能量冲击。电荷等动态静电参数的测量比较困难。作者选择了四种测量方法。本测试方法是根据作者的静电参数知识和专门测量静电参数的欧洲标准编写的。这些电路是为四种不同的火花参数准备的。火花流静电场的测量方法不能测量火花的场势。测量仪器没有这么快的响应时间,足以满足火花的速度。进行了火花产生和参数测量实验。确定火花上静电电荷量的唯一方法是通过在测量电极处收集火花来测量整个电荷。测量系统要求整个火花流落在电极上。测试的火花流传递静电电荷约为10nc。这意味着这种装药可以成为一些爆炸性环境的有效点火源。静电电荷的某些方法被拒绝,因为不充分的后续结果分析。其中一种方法的权利要求已提交给波兰共和国专利局。

Mechanical Spark Electrostatic Property Testing Method
Abstract The article describes an attempt to assess the electrostatic properties of mechanical friction-induced sparking. Such sparks are the cause of numerous accidents in hard coal mines. The article summarizes accidents in hard coal mining in Poland in recent years. In most cases, the initials were mechanical sparks. Mechanical sparks contain energy, a part of which is related to their excess electrostatic charge, whereas the other part is of a different origin (kinetic or thermal energy, for example). The article tries to estimate how much of this energy is energy impact generated by electrostatics impact. It is hard to measure the dynamic electrostatic parameters like electric charge. Authors select four measuring methods. This test methods are prepared based on authors knowledge of electrostatic parameters and European standards dedicated to measure the electrostatics parameters. These circuits were prepared for four different spark parameters. Measurement methods of electrostatic field of sparks stream are not able to measure field potential of sparks. The measuring instruments do not have such a fast response time, adequate to the speed of the sparks. Spark generation and parameter measurement experiments were performed. The only method to determine the amount of electrostatic charge on sparks is to measure the entire charge by collecting sparks at the measuring electrode. The measuring system requires that the entire stream of sparks falls on the electrode. Tested transferred electrostatic charge of stream of sparks is about 10 nC. It means that this charge can be an effective ignition source for some explosive atmospheres. Electrostatic charge with Certain methods were rejected as inadequate following result analysis. A claim for one of the methods was submitted to the Patent Office of the Republic of Poland.
