无局放试验变压器广泛应用于电器、电缆、电机、变压器、互感器、绝缘材料和相关的高压元件制造厂家,以及电力、科研和大专院校的高压试验室,可对其产品进行局部放电和工频耐压试验。

1.局部放电量

110-200KV额定高压输出,在100%UH下局部放电量≤3-5PC

2250-300KV额定高压输出,在100%UH下局部放电量≤5PC

3350-750KV额定输出,在80%UH下局部放电量≤5PC100%UH下≤10PC

480KV-1500KV额定高压输出,在80%UH下局部放电量≤10PC

2.串接式变压器,变压器电压分布不对称度≤5%

3.试验变压器在额定电压额定电流下,从环境度开始,可运行30min

在三分之二额定电压三分之二额定电流下,可连续运行。

4.单台试验变压器阻抗为3%-12%,串接阻抗为5%-40%

5.波形畸变率<5%

6.其余参数符合ZBK41006-89〈试验变压器〉规定。
