调气隙式属于随动式补偿系统。其消弧线圈属于动芯式结构,通过移动铁芯改变磁路磁阻达到连续调节电感的目的。然而其调整只能在低电压或无电压情况下进行,其电感调整范围上下限之比为2.5倍。
The air gap type belongs to the follow-up compensation system. The arc suppression coil belongs to the movable core structure, and the inductance can be continuously adjusted by changing the reluctance of the magnetic circuit by moving the iron core. However, it can only be adjusted at low or no voltage, and the ratio of upper and lower limits of inductance adjustment range is 2.5 times.
控制系统的电网正常运行情况下将消弧线圈调整至全补偿附近,将约100欧电阻串联在消弧线圈上。用来限制串联谐振过电压,使稳态过电压数值在允许范围内(中性点电位升高小于15%的相电压)。当发生单相接地后,必须在0.2S内将电阻短接实现最佳补偿,否则电阻有爆炸的危险。
Under the normal operation of the control system, the arc suppression coil is adjusted to the vicinity of full compensation, and about 100 Euro resistance is connected in series to the arc suppression coil. It is used to limit the series resonance overvoltage so that the steady-state overvoltage value is within the allowable range (the neutral point potential increases less than 15% of the phase voltage). When single-phase grounding occurs, the resistance must be shortened within 0.2S to achieve the best compensation, otherwise the resistance will be in danger of explosion.
