Abstract
Preventive testing is a key measure to ensure long-term reliable operation of electrical equipment.Based on this,this paper analyzes the main types of electrical equipment in small hydropower stations,analyzes the problems encountered by these equipment during operation,introduces in detail the necessity of preventive testing,and emphasizes that potential trouble hazards of equipment can be discovered in time through regular testing,so as to avoid major accidents.In terms of test methods,this paper summarizes the currently commonly used electrical equipment test techniques,such as insulation resistance test,dielectric loss tangent test,partial discharge detection,etc.,and discusses the advantages and disadvantages of these methods.At the same time,this paper also discusses the principles for determining the test period,and puts forward suggestions for comprehensive consideration based on factors such as equipment type,operating environment and historical data,so as to provide reference for technicians and managers in relevant fields to ensure efficient operation of hydropower stations.关键词
