Design of Dynamic Link Library for Data Acquisition of Partial Discharge in Power Cable
摘要
Abstract
It is difficult to sample the partial discharge signal of power cable because of its weak magnitude and wide frequency spectrum from 2 kHz to 300MHz.The data acquisition board PX15154, Multi-channel switch PX12593 and the computer system produced by National Instrument Co., LTD were used to be the platform for data sampling.Dynamic link library (DLL) was designed to sample the partial discharge signal.The data of partial discharge was fetched by txt form for deeply study to obtain the characteristic.DLL has good compatibility with the sampling boards of NI.DLL can be replanted to the other field with little change.关键词
