摘要
详细分析了泵站接地装置在实际工作中存在问题,引起雷击时避雷器不动作,造成用电设备损坏等现象,提出了防腐、降阻、设水下接地网等处理措施,以及在电气设计时,从材料选择、接地网的布置方式采取的措施,保证泵站接地的安全性、可靠性,确保人身和设备的安全。
The existed problems for grounding equipment of pumping stations in practical work are analyzed here, which would cause the lightning arrester not to operate, resulting in damages of electrical equipments. Based on this, the treatment measures are put forward such as the preserving, resistance reducing and locating underwater grounding network. At the same time, the measures are taken from material selection and grounding network layout in electrical design, so as to ensure the safety and reliability of grounding, as well as the safety of persons and equipments.
