Abstract
In allusion to the phenomenon of abnormal heating at the joint where the optical fiber composite overhead ground wire （OPGW） is connected to the truss of substation, the on-site measurement of the induced current and voltage of the grounding circuit of OPGW was performed, and based on the measured results the reason causing the abnormal heating was analyzed. Analysis results showed that the bad contact of OPGW with the truss made the grounding current of OPGW transferring to the circuit of tensional joint and the heating power was larger and concentrated. On this basis the simulation research on induced current of OPGW and heating power are conducted, and simulation results basically conform to the measured data. Research results show that power flow of transmission line, tower grounding resistance and contact resistance of the joint where OPGW is connected to the truss differently influence on the shunt of grounding current of OPGW and the heating power.关键词
