摘　　要：发热点属于开关内的静触头松动和引下线与母线连接面接触不良，造成氧化后长时间过热而造成损坏，其热量是会通过空气介质传播到开关柜表面的，此时如果通过对开关柜表面的温度场进行横向和纵向的比较。Hot Point is damaged caused by long - time heating after oxidation, because the fixed contact in switch loosens and the downlead and bus contract poorly. Its heat spreads to the surface of switchboard by the air, by this time it is needed to compare the vertical and horizontal temperature field of the surface of switchboard.
