关于“必须采用自动调整补偿装置”规定的商榷

Discussion on the Stipulation of "Autoadjusting Compensation Device Must Be Adopted"

结合实践论述了采用手动调整补偿的国产消弧线圈作为过渡性的措施,以解决煤矿6kv电网单相接地电容电流大大超过20A规定的问题是可行的。只要加强管理,采用较大脱谐度的过补偿方式运行,不会发生谐振过电压问题。

Combining with practice, this article discusses that it is practicable to use the domestic arc extinguishing coil with manumlly adjusting compensation as the interim measure, so as to solve the problem of the single phase grounding capacitive current considerably exceeding the regulated 20A in 6kv network of coat mines. As long as the management is strengthened and the operation in over compensation mode with comparatively Large offresonance is adopted, the resonance overvoltage problem could not occur.
