摘要
平衡水池是特高压换流站阀外冷系统的关键组成部分,为保证平衡水池储备水质符合要求,每年会对平衡水池进行检查及清洗。现有平衡水池抽水方式一般为临时潜水泵抽水,耗时较多,严重影响作业效率。此外,平衡水池储备水可作为消防作战车的后备水源使用,但现有衔接方式不合理。针对上述两个问题,提出了一种平衡水池抽水系统,对水池抽水功能进行了完善,大幅提升平衡水池储备水转移效率的同时,优化了平衡水池与消防作战车的衔接方式,提升了特高压换流站的消防能力。
The balance pond is a key component of the valve cooling system of the UHV converter station.To ensure that the quality of reserved water in the balance pond meets the requirements,the pond is checked and cleaned annually.Submersible pumps,temporarily used in the balance pond,are time-consuming and hold up work efficiency.In addition,the water stored in the balanced pond can be used as the backup water source for fire trucks,but the existing connection method is not reasonable.In view of the two problems above,this paper proposes a balanced pond pumping system,which improves the pumping function of the pond,greatly improves the transfer efficiency of the reserve water of the pond,optimizes the connection mode between the pond and the fire trucks,and improves the fire service capability of the UHVDC converter station.
