摘　　要：为了给输电线路低压侧杆塔上的在线监测设备供电,提出一种新型沿悬式绝缘子串进行电力传输的方法,以悬式绝缘子串作为能量传输的载体,将输电线路上在线取能装置获得的电能通过高频变换的方式传递杆塔一侧,通过实验验证方法的可行性。搭建绝缘子串传输特性实验平台,并对频率、绝缘子串数量和绝缘子型号对传输效率的影响进行研究。实验结果表明:以绝缘子串为载体进行电能传输具有较高的传输效率,如500 kV输电线路用30片绝缘子串传输效率为72.6%,而220 kV输电线路用14片绝缘子串的传输效率可达91.27%。由此可见,利用悬式绝缘子串作为能量传输载体为杆塔在线监测设备供电具有可行性。In order to supply power to the on-line monitoring equipment on the low-voltage side tower of the transmission line,a new method of power transmission along the suspension insulator string is proposed.The suspension insulator string is used as the carrier of energy transmission,and the online energy-taking device on the transmission line is obtained.The electric energy is transferred to the side of the tower by means of high frequency conversion,and the feasibility of the method is verified by experiments.An experimental platform for transmission string transmission characteristics was built,and the effects of frequency,number of insulator strings and insulator type on transmission efficiency were studied.The experimental results show that the power transmission with insulator string as carrier has higher transmission efficiency.For example,the transmission efficiency of 30 insulator strings for a 500 kV transmission line is 72.6%,and the transmission efficiency of 14 insulator strings for a 220 kV transmission line can reach 91.27%.It can be seen that it is feasible to use the suspension insulator string as the energy transmission carrier to power the tower online monitoring equipment.
