摘要

在实验室对开线线路中埋地电缆供电的垫式配电变压器的防雷进行了研究。多台配电变压器和场长等效电缆连接，形成典型的有限尺寸地下配电布置。在每台变压器上提供阀式避雷器的成本和空间限制，强调仅从电缆开路导线结避雷器获得全面保护。考虑了波形、电缆长度和特性的影响，以及变压器基本脉冲绝缘等级(BIL)的关系。

The Surge Performance of Cable-Connected Pad-Mounted Distribution Transformers

The lightning protection of pad-mounted distribution transformers supplied through buried cable from open-wire circuits was investigated in the laboratory. Several distribution transformers and field lengths of equivalent cable were connected to form a typical underground distribution layout of limited size. Cost and space limitations in providing valve-type arresters at each transformer place emphasis on obtaining over-all protection from only the cable-open wire-junction arresters. The influence of wave shape, cable length and characteristics, and the relation of the transformer basic impulse insulation level (BIL) were considered.
