Research and Practice on Improving the Reliability of Power Supply for 10 kV Overhead Lines in Water Intake Pump House
With the increase of dual unit utilization hours of Yunnan Huadian Zhenxiong Power Generation Co.,Ltd.,the frequency of starting and stopping three water intake pumps has significantly increased,and the problem of frequent drop type fuse failures at the moment of starting the water intake pumps is becoming increasingly prominent.This paper analyzes and studies the frequent occurrence of faults in drop type fuses,formulates solutions,and implements them.After implementation,the problem of frequent failures of drop type fuses was completely solved,greatly reducing maintenance costs,shortening maintenance periods,reducing safety risks during maintenance,and significantly improving the power supply reliability of 10 kV line in the water intake pump house.
