維修PEWATRON電流互感器
閱讀:517 發(fā)布時間:2020-6-8PEWATRON 電流互感器 2877
大內(nèi)徑裝置產(chǎn)生高壓電流測量無電壓擊穿的風險
雙屏蔽更大的噪聲免疫力和增加在高電壓應用的安全
所有型號的密封,適用于高電壓絕緣油或真空
可以連接到示波器、頻譜分析儀、功率分析儀、數(shù)字電壓表、
模擬-數(shù)字轉(zhuǎn)換器,和其他各種測量儀器
PEARSON介:美國皮爾遜Pearson Electronics1958年變開始設計和生產(chǎn)監(jiān)測變壓器經(jīng)過幾十年的發(fā)展產(chǎn)品廣泛應用于美國軍工、醫(yī)療、航空等領域一直服役于極其復雜的瞬間信號和一些頻率周期性信號環(huán)境下奠定了它精確高品質(zhì)的要求電流測試環(huán),國內(nèi)也稱電流互感器或電流傳感器,電流互感器的運行情況相當于次側(cè)短路的變壓器,忽略勵磁電流,安匝數(shù)相等電流互感器一次繞組電流與二次繞組的電流比,叫實際電流比
