Background technology
The insulation meeting of XLPE power cable is deteriorated due to chemistry, heat and the factor such as electric. Water tree phenomenon is considered to one of aging major reason. Therefore some researchers think the groundwork of XLPE cable insulation ag(e)ing diagnosis is how before puncturing, to monitor water tree. Find, in the time that operating XLPE cable insulation contains water tree, little flip-flop is present between conductor cores and copper shield, and this flip-flop is that in insulation, water is set the cracking feature causing. By measuring flip-flop, diagnosing insulation is aging is possible as water tree result. Flip-flop method cardinal principle is to utilize in cable to have water to set the rectifying effect while existence. In the time of the negative half-cycle of applied voltage, water tree injects more negative electrical charge by tip in insulation, and the positive charge injecting in the time of positive half period is less, so that only neutralized a part of electric charge. Under the effect of cable operation power-frequency voltage, the negative electrical charge of water tree front end is gradually to the other side's drift, occurred flip-flop but numerical value is very little just as rectified action, only has a few to tens of to receive peace. The development of water tree often illustrates the increase of leakage current, and such deterioration process causes the decline of ac breakdown voltage.
