Product Introduction

变压器、GIS系统、SF6开关、CT/PT、绝缘子、母线、电缆、套管等容性设备是变电站中常见的一次电气设备。根据220V以及以下变电站一次电气设备耐压的试验规程要求,相应的交/直流流耐试验设备既要满足高电压、小电流的试验条件,又要满足低电压,大电流的试验条件,要求兼顾较宽的适用范围,采用串联谐振的原理,由变频电源控制箱(操作台)、激励变压器、电抗器、电容分压器组成了主设备,在电容分压器上,接入整流硅堆及微安表,即可完成直流耐压试验。由于系统谐振后具有很好的滤波特性,因此其生产的直流电压优于普通试验变压器整流初来的直流电压。是地、市、县级高压试验部门及电力承装、修试工程单位的耐压设备。

Performance characteristics

1、所需电源容量大大减小,试验所需的电源功率只有试验容量的1/Q;

2、体积小,重量轻,一般为普通试验装置的1/3-1/5;

3、谐振电源是谐振式滤波电路,能改善输出电压的波形畸变,获得很好的正弦波形,有效的预防了谐波峰值对试品的误击穿;

4、变频电源保护功能强,稳定性好;

5、具备多种工作模式,操作方便;

6、采用220V或380V单相电源,方便现场取电;

7、配置灵活,扩展功能强。谐振电抗器采用多只方式,积木式组合,可串可并,满足多种试品的试验要求,更方便现场使用。
