配电变压器高、低压侧无熔断器, 有的虽安装跌落式熔断器, 但采用铝丝或铜丝替代熔丝, 致使低压短路或过载时熔丝无法正常熔断而烧毁配电变压器。配电变压器的高、低压熔体配置容量过大, 从而造成配电变压器严重过载时烧毁配电变压器。

在配电变压器投运前, 严格安装高、低压熔体, 同时测试负荷情况，分析原因。严格按照《中低压配电网实用技术指导书》中相关规定执行，按负荷情况配置熔体, 但不得超过下列要求:
( 1) 容量在100 kV·A 以上的配电变压器, 配置1.5～2.0 倍额定电流的熔体;
( 2)容量在100 kV·A 以下的配电变压器, 配置2.0～3.0 倍额定电流的熔体;
( 3) 低压侧熔体应按额定电流稍大一点选择。
