110 kV双回路转角塔等电位作业进电场装置的研制与应用

在110 kV双回路转角塔等电位作业时，传统等电位作业进电场的方式无法满足等电位作业安全距离，因此，分析研究110 kV双回路转角塔的结构特点，并参考“塔吊”的工作原理，研制了一种等电位作业进电场装置，改变传统带电作业进电场的方式和路径，增大组合间隙，保证了作业人员在110 kV双回路转角塔开展等电位作业时进入强电场的安全距离，具有很强的实用性，保证供电可靠性。

Development and application of electric field device for equipotential operation of 110 kV double circuit angle tower

Aiming at the problem that the traditional way of equipotential operation into the electric field can not meet the safe distance of equipotential operation in 110 kV double circuit angle tower, the structural characteristics of 110 kV double circuit angle tower was analyzed and studied. An equipotential operation into the electric field device was developed referring to the working principle of "tower crane". The results show that the device changes the way and path of traditional live working into the electric field, increases the combined gap, and ensures the safe distance for operators to enter the strong electric field when carrying out equipoten? tial operation in 110 kV double circuit angle tower. It has strong practicability and ensures the reliability of power supply.
