Study onmeasurement device fortransfer over voltage of GIS    transber
Abstract：In order tomeasure the transfer VFTO of GIS voltage transber, this paper developed ameasurement and control device which based on Lab VIEW 8.6 Workbench. Usingthis device to test the transmitted over voltage of 110kV GIS Voltagetransber, the result showed that the device not only can meet therequirements of IEC and national standards, but also be flexible and reliableto use, which can be well applied to the transber type test and research oftransmitted over voltage characteristics.
Key words：GIS; voltage transber;B class shock; transfer over voltage; measurement device

氣體絕緣開關(guān)設(shè)備（gas insulatedswitchgear, GIS）中隔離開關(guān)例行操作常會引起頻率1-100MHz的特快速瞬態(tài)過電壓（FANUC A16B-1210-0430VFTO）[1-2]。電力系統(tǒng)的正常運(yùn)行中如果這種過電壓從高電壓系統(tǒng)傳遞到低電壓系統(tǒng)，就有可能對低電壓系統(tǒng)的電器設(shè)備造成損害，影響電氣設(shè)備的安全運(yùn)行[3-4]。GIS電壓互感器本身就是電容分壓和電磁感應(yīng)原理進(jìn)行電壓測量的線路器件。由于GIS電壓互感器接于線路對地之間，所以這種過電壓要傳遞到二次測量回路，使二次測量設(shè)備承受來自一次回路的傳遞過電壓，在GIS運(yùn)行中也出現(xiàn)過互感器傳遞過電壓造成二次設(shè)備危害的問題[5-6]。----商務(wù)熱線---廈門興銳達(dá)自動(dòng)化設(shè)備有限公司
