Abstract:

Base on the overheat of connection point of high voltage transmission line lightning conductor incomer and transformer gatetype frame, far infrared technology was adopted and diagnosed a heating defect of connection metal fitting. The causation and creation condition of heating was analyzed. The onsite treatment and result of heat defect was introduced. Advices for transmission line lightning conductor insulation joint design was introduced. Which could be referred by similar situation.
