摘　　要： 研制了基于模块化结构的消弧接地一体化装置,将消弧线圈和接地选线做成完全独立的两个模块,以提高应用的灵活性和可靠性,模块之间无需相互通信,以零序电压作为同步信号,消弧线圈配合接地选线协调动作,使选线的准确率得到大幅度的提高。实验室模拟电网接地试验和现场挂网运行情况表明,一体化装置电容电流测量、补偿准确,选线结果正确,应用灵活,运行可靠。 A new incorporate device of automatic arc-suppression coil and grounding fault line selection based on module structure is developed to improve its application flexibility and reliability. Arc-suppression coil and fault line selection are designed to be two absolutely independent modules. When single-phase grounding fault occurs, the modules are not synchronized by communication between them but by system zero-sequence voltage. And arc-suppression coil module operates to match fault line selection module in harmony when grounding fault occurs. Then their independent hardware and grounding fault subprograms in which the two part cooperation is considered＇ are given. Grounding experiment results in simulate network and site operations show that the incorporate device measures and compensates system capacitor current accurately, selects fault line rightly, applies flexibly and operates reliably.
