YNXZ-D电缆交流耐压试验装置适用于10kV、35kV等电缆的交流耐压试验,变频串联谐振耐压试验是利用电抗器的电感与被试品电容实现电容谐振,在被试品上获得高电压、大电流。电缆交流耐压试验装置主要由变频电源(主机)、励磁变压器、谐振电抗器、电容分压器组成。
YNXZ-D电缆交流耐压试验装置频率的调节范围为30~300Hz,符合南方电网公司发布的企业标准《电力设备预防性试验规程》不但能满足高压 XLPE电缆的耐压要求,而且具有重量轻(单个部件重量不超过30kg)、可移动性好的优点,适宜现场试验。
YNXZ-D电缆交流耐压试验装置中的谐振电抗器,励磁变压器采用干式环氧浇注,适合各类电缆的要求。
1、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;
2、本系统要求单个人能现场搬动的部件重量不超过30kg,要求两个人能现场搬动的部件重量不超过60kg,适合现场搬运;
3、电源采用220V单相电源或380V单电源,方便现场取电;
4、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;
5、110kV及以上电压等级电缆耐压试验采用油浸式电抗器,在单体重量超过100kg时,可选配我公司小型电动吊车。
1、额定输出电压:0~220 kV (有效值)及以下
2、输出频率:30~300Hz
3、谐振电压波形:正弦波,波形畸变率≤1%
4、满负载工作时间:连续工作时间60min
5、系统品质因数:负载下≥20
6、频率调节细度:0.1Hz,不稳定度≤0.01%
7、工作电源:220V或380V单相市电
