| 摘 要： | 过去为保障电力系统的安全运行,常常采用定期试验维修电气设备的方法,这种离线试验方法确实有一定的效果,但时常也会碰到经过试验维修合格的设备投入生产后不久就出现事故的情况.电缆是一种特殊的电力设备,采用直流耐压试验方法对电缆本身会造成一定的损伤,会加快电缆的老化,影响电缆的绝缘特性.虽然直流耐压试验目前仍然是一种有效的发现故障的方法,但随着科学技术的进步和试验条件的不断改善,人们一直在不停的寻求新的试验方法能够代替这种破坏性试验.

| Abstract: | In the past,electrical equipment usually took routine test method to ensure safe operation of power system,and this kind of off-line test method that made a great contribution for electric utility.But we also often have problem that qualified equipment after maintain is fail before long putting into operation.In fact,power cables as kind special electric equipment will be damaged by itself in testing with DC withstand voltage test method,etc.Meantime,that also speeds up ageing and affects dielectric properties of cable.Although DC withstand voltage test is still one effective solution to find fault,with the Scientific and technological progress and experimental conditions improvement,we have been constantly seeking new testing method to replace the destructive testing |
