10kV消弧线圈装置的选型及其应用

The Selection and Application of 10kV Arc-suppression Coils

根据实际使用案例,分析比较了各种不同原理的自动跟踪消弧线圈系统,重点指出了它们的特点和不足。调容式消弧线圈电容单元组合灵活,更适宜应用在发展中的电网;调匝式消弧线圈运行已在各类电网中广泛应用;相控式消弧线圈自动跟踪时间短,较适宜应用在电容电流时常变化的电网。

According to the actual engineering examples, arc-suppressing coil apparatus with automatic tracking and compensation based on different theory are analyzed, and their advantages and disadvantages are emphatically given. There is flexible unit combination for arc-suppression coil of multi-capacitors type, which is better for the developing power grid~ The multi-tap arc suppression coils have operated for a long time, and are widely used. Phase-controllable arc-suppression coils have shorter automatic tracking time, and are more fit for the grid in which capacitive current often change.
