执行标准：DL/T849.6-2004
XGTF系列 电缆变频串联谐振耐压装置采用了调节电源的频率的方式使得电抗器与被试电容器实现谐振，在被试品上获得高电压大电流，是当前高电压试验的一种新的方法和潮流，在国内外已经得到广泛的应用。
XGTF系列 电缆变频串联谐振耐压装置采用了专用的SPWM数字式波形发生芯片，频率分辨率16位，在20~300Hz时频率细度可达0.1Hz；采用了正交非同步固定式载波调制方式，确保在整个频率区间内输出波形良好；功率部分采用了先进的IPM模块，在*小重量下确保仪器稳定和安全。
XGTF系列 电缆变频串联谐振耐压装置由调频调压电源、励磁变压器、电抗器、电容分压器组成。XGTF系列 电缆变频串联谐振耐压装置产品特点：● 35kV及其以下电压等级的电缆使用数量多，试验工作量大，所以此类耐压试验装置体积小，重量轻，便携式电缆耐压试验系统由此而诞生；
● 本系统要求单个人能现场搬动的部件重量不超过30kg，适合现场搬运；
● 电源采用220V单相电源或380V单相电源，方便现场取电；
● 电抗器部分采用干式环氧浇注，美观可靠，适合各类电缆的要求。XGTF系列 电缆变频串联谐振耐压装置技术参数：● 额定输出电压：0～66kV(有效值)及以下
● 输出频率：20～300Hz
● 谐振电压波形：正弦波，波形畸变率≤1%
● 满负载工作时间：连续工作时间60min
● 系统品质因数：*大负载下≥20
● 频率调节：细度0.1Hz，不稳定度≤0.01%
● 工作电源：220V或380V单相市电
