Quality Inspection and Analysis of Contact Element of Disconnector
The problem of contact overheat of disconnector is very common in the problem of disconnector.The quality of the contact element is directly related to the operation quality of the disconnector.In this paper,the principles and methods of contact touch material,coating and hardness are briefly described.The materials and coatings of the improved and ordinary spring sheets are collected,and the materials,coatings,thickness and hardness of the improved and ordinary type contact touch are tested.Tests showed The improved contact silver plating layer thickness and hardness are higher than the technical standards of the State Grid,the com-mon contact materials,coating thickness,hardness does not meet the requirements,should be improved,im-proved isolation switch memory alloy spring compared with ordinary spring,with more elasticity and excellent corrosion resistance.
