玻璃厂电能质量故障案例分析
玻璃厂电能质量故障案例分析。客户在一家新的玻璃工厂中反复出现电气控制和仪器故障。是电能质量问题导致的该情况！工厂已从60Hz国家进口到50Hz国家。在这种情况下，由于频繁的停工和停工，新工厂的产能减少了 50% 或更多。维修电子产品的成本仅占每次故障总成本的一小部分。“你不只是关闭玻璃厂”。客户试图用电压表和简单的电源监视器来确定问题的根源。他们无法捕捉到破坏性的电压变化。现有的两款仪表的图表显示电压没有明显变化。例如，请参阅图1：线到线和线到中性RMS值未显示高电压变化。
A case study of electronic control failure in a glass factory
The customer had repeated electrical control and instrument failures in a new glass factory. The factory has been imported from 60Hz countries to 50Hz countries. In this case, the capacity of the new plant was reduced by 50% or more due to frequent shutdowns and shutdowns. The cost of repairing electronics is only a fraction of the total cost per breakdown. "You're not just closing down the glass factory". The customer tried to identify the source of the problem with a voltmeter and a simple power monitor. They can't catch damaging voltage changes. The graph of the meter shows no significant voltage changes. Refer to Figure 1 for example the line-to-line and line-to-neutral RMS values do not show the high voltage variation.
我们在 400 伏总线级别安装了Dranetz电能质量监控器。结果如图 2 所示。请注意，峰值电压图清楚地显示了 PG4400 独特的电压峰值记录功能记录的多个高压瞬变。图3显示了电压瞬变的细节。为了找到瞬变的来源，我们在 10Kv 的源电压下安装了额外的 Dranetz 电能质量分析仪 PX-5 和 PG4400 显示器。图 4 显示了具有 PG4400 峰值记录功能的 10KV 电压瞬变的详细信息。
We installed a Dranetz power quality monitor at the 400-volt bus level. The results are shown in Figure 2. Note that the peak voltage plot clearly shows the multiple high voltage transients recorded by the PG4400's unique voltage peak recording capability. Figure 3 shows the details of the voltage transient. To find the source of the transients, we installed additional Dranetz Power Quality Analyzer PX-5 and PG4400 displays at a source voltage of 10Kv. Figure 4 shows the details of a 10KV voltage transient with the PG4400 peak recording capability.
基于这些证据，我们确定存在多个电压瞬变源。其中一个来源来自10KV电压水平，如这些图表所示。第二个来源在一个单独的项目中进行了调查。
Based on this evidence, we determined that there were multiple sources of voltage transients. One of the sources comes from the 10KV voltage level, as shown in these charts. The second source was investigated in a separate project.
