PLC控制型漏电起痕试验装置是按相关标准要求设计制造专用检测仪器,主要用于测定固体电气绝缘材料在电场作用下表面暴露于含杂质的水时的耐漏电起痕指数进行耐漏电起痕性能测试。
在电器产品受潮湿和杂质环境的影响下,不同极性带电部件之间或带电部件与接地金属之间可能会引起绝缘上的漏电,产生的电弧对电器造成击穿短路或由于放电使材料电蚀损,甚至起燃导致火灾。漏电起痕试验就是模拟上述情况对绝缘材料进行的一种破坏性试验,用以测量和评定在规定电压下,绝缘体在电场和含杂质水的作用时的相对耐漏电起痕性,适用于电工电子产品、家用电器的固体电器绝缘材料及其产品,如:继电器插座、转换开关盖、PCB板、接触器等……
PLC控制型漏电起痕测试仪采用全不锈钢箱体,观察窗口大;进口高精度数显仪表,外形美观;集多项国内外耐漏电起痕产品的优点,用料出众,做工优良,性能稳定,操作方便采用目前最先进的PLC控制,做到全智能化控制方式,真正实现网络化及远程控制;可做到客户的人性化操作界面的升级,真正达到国际比对结果。
