一次消谐装置
一次消谐装置应用功能
Application function of primary harmonic elimination device
1、压变的铁磁谐振产生的过电压常使设备内绝缘击穿、外绝缘放电，且常因事故处理不及时或事故扩大而造成大面积停电
1. The overvoltage produced by the piezoelectric ferroresonance often causes the insulation breakdown in the equipment and the external insulation discharge, and it often causes large area blackout due to the accident treatment and the accident expansion.
2、电网中的弧光接地使电压互感器频频烧毁。使用消谐器可有效地解决上述问题：消除或阻尼压变非线性励磁特性而引起的铁磁谐振过电压，这种谐振过电压会导致系统相电不稳定；能有效抑制间隙性弧光接地时流过压变绕组的过电流，防止压变烧毁；限制系统单相接地消失时在压变一次绕组回路中产生的涌流，这种涌流会损坏压变或使压变熔丝熔断；当系统发生单相接地后可较长时间保护压变免受损坏。
2, the arc grounding in the power grid makes the voltage transformer burn down frequently. The use of the harmonic eliminator can effectively solve the above problem: the ferromagnetic resonance overvoltage caused by eliminating or damping the nonlinear excitation characteristics of the system, this kind of resonant overvoltage can cause the system phase electric instability; it can effectively restrain the overcurrent flowing through the voltage changing windings in the gap arc grounding, prevent the pressure change to burn down, and limit the single-phase grounding of the system. Inrush current produced in a voltage changing winding circuit when disappearing, this inrush will damage the pressure change or cause the fuse to fuse; when the system occurs single-phase grounding, it can protect the pressure from damage for a long time.
