核电厂中压电气贯穿件局部放电试验的研究

介绍了三代核电站AP1000中压电气贯穿件功能和电气参数,以及IEEE 317—1983、GB13538—1992对中压电气贯穿件局部放电试验的要求,依据其试验要求和电气参数,利用局部放电测量法中的脉冲电流法设计了一套局部放电试验电路,通过对比试验提出了可降低中压电气贯穿件局部放电量的结构改进方案,对试验过程中干扰识别及抗干扰措施做了详细分析。

Experimental Study on Partial Discharge Test of Medium-voltage Electrical Penetration Assemblies for Nuclear Power Station

An introduction was presented to functions and electric parameters of the medium-voltage electrical penetration assembly for AP1000 third-generation nuclear power stations, as well as to the requirements of IEEE 317--1983 and GB 13538--1992 on the partial discharge test. A set of partial discharge test circuit was designed by the pulse current method of partial discharge measurement approach according to above test requirements and electric parameters, and a structural improvement scheme was put forward by contrast test that can reduce the magnitude of partial discharge of the medium-voltage electrical penetration assembly, while corresponding interference identification in test process and relevant anti- interference measures analyzed in details.
