产品介绍：
超低频高压发生器 XGVLF-80/0.5
执行标准：DL/T 849.4-2004
XGVLF 系列0.1Hz程控超低频高压发生器结合了现代数字变频先进技术，采用微机控制，升压、降压、测量、保护完全自动化，并且在自动升压过程中能进行人工干预。由于全电子化，所以体积小重量轻、大屏幕液晶显示，清晰直观、且能显示输出波形、打印机输出试验报告。设计指标完全符合《电力设备专用测试仪器通用技术条件，第4部分：超低频高压发生器通用技术条件》电力行业标准，使用十分方便。现在国内外均采用机械式的办法进行调制和解调产生超低频信号，所以存在正弦波波形不标准，测量误差大，高压部分有火花放电，设备笨重，而且正弦波的二，四象限还需要大功率高压电阻进行放电整形，所以设备的整体功耗较大。本产品均能克服这样一些不足之处。
超低频高压发生器 - 技术特点
● 电流、电压、波形数据均直接通过高压侧采样获得，所以数据真实、准确。
● 过压保护：当输出超过所设定的限压值时，仪器将停机保护，动作时间小于20＇毫秒。
● 过流保护：设计为高低压双重保护，高压侧可按设定值进行精确停机保护；
● 低压侧的电流超过额 定电流时将进行停机保护，动作时间都小于20＇毫秒。
● 高压输出保护电阻设计在升压体内，所以外面不需另接保护阻。
● 由于采用了高低压闭环负反馈控制电路，所以输出无容升效应。
