Abstract
Description
电弧接地可能性 | 可能 | 不可能 | 不可能 | 如电抗值大,可能 | 不可能 |
单相接地时的电磁感应 | 如不发展为双重接地时,小 | 最大,断路器迅速断开,持续时间短 | 中等,电阻值大时,感应值较小 | 中等,电抗值大时感应值小 | 小,特别当配置适当时更小,但持续时间较长 |
工作时引发串联谐振的可能性 | 不会 | 不会 | 不会 | 不会 | 有可能 |
短路时对通信线的感应 | 小,但当双重接地或中性点偏移时产生感应,而且时间较长 | 大,但采用快速切除故障时,持续时间短 | 中,当电阻值大时,感应值较小 | 中,当电抗值大时,感应值较小 | 小,适当配置时更小,但持续时间较长 |
平时对通信线的感应 | 中性点偏移时,产生静电感应 | 小,但应考虑变压器及电晕的三次谐波影响 | 多重接地情况下较小 | 多重接地情况下较小 | 共振时产生感应 |
对无线电干扰 | 当事故时或中性点偏移时,可能较大 | 小 | 事故时较直接接地大 | 事故时较直接接地大 | 事故时,可能较大 |
单相接地的持续时间 | 大 | 最小 | 电阻大时,大 | 电抗大时,大 | 大 |
短路时切除故障的要求 | 如连接线路短可以消除事故;如连接线路长,则事故段必须隔离 | 事故段必须隔离 | 事故段必须隔离 | 事故段必须隔离 | 事故时一般可以自然消弧;永久故障时,必须将事故段隔离 |
