行业现状<\/span><\/strong><\/span><\/span><\/span> <\/p>

<\/p>

绝缘耐压试验分为<\/span>直流耐压试验<\/span><\/strong>和<\/span>交流耐压试验<\/span><\/strong>两种。过去在进行电缆耐压试验时都采用直流耐压试验。在1980年左右，国外电力部门发现直流耐压试验对橡塑绝缘是无效的且具有危害性。我国在九十年代开始研究和实践交流耐压试验技术。经过20多年的研究和实践，世界各国纷纷采用交流耐压试验代替直流耐压试验。国内外有关标准机构也对于高压电缆的试验方法作出了更改和修订。1997年CIGRI国际大电网工作会议对目前采用的直流耐压试验方法提出疑议，并推荐使用工频及近似工频（30-300HZ）的交流试验方法，在全世界范围内推广应用。我国的华北电力集团，广东，江苏，浙江，福建，安徽等电网已先后颁发《试验规程》，强制规定用交流耐压试验代替直流耐压试验。在我国电网相对发达的省份，交流耐压试验已经成为强制性标准。其它地区的试验规程也在起草和酝酿中。<\/span>交流耐压试验取代传统直流耐压试验已是大势所趋。<\/span><\/strong> <\/p>
