According to the indexes of the electricity generating performance and their affecting factors , a system with a hall displacement transducer and a charge amplifier to measure the vibration amplitude of the pec and the quantity of electric charge was developed 根據(jù)壓電陶瓷發(fā)電性能指標(biāo)以及影響因素,設(shè)計(jì)了采用霍爾位移傳感器和電荷放大器對(duì)壓電陶瓷振幅和電荷量進(jìn)行測(cè)量的系統(tǒng)。
Experiments of quantity of electric charge analysis and fault diagnosis by the device are carried out to show that it is not only able to run reliably , but also provide fine performance in excitation adjusting and online fault diagnosis 最后,論文對(duì)該故障診斷裝置進(jìn)行了電量測(cè)量精度實(shí)驗(yàn)和故障診斷實(shí)驗(yàn)。實(shí)驗(yàn)結(jié)果表明,該裝置運(yùn)行穩(wěn)定,具備勵(lì)磁調(diào)節(jié)能力,且能夠有效對(duì)勵(lì)磁系統(tǒng)故障進(jìn)行在線監(jiān)測(cè)和診斷。
