摘要
谐振是在电力系统应用中普遍存在的现象,尤其是在高压试验中应用较为广泛。为掌握高压试验中利用谐振的方法,明确试验中无功补偿情况,分析从谐振的基本原理入手,对高压试验中利用谐振进行高压耐压试验的原理进行了总结,通过与现场高压试验结果进行印证,理论计算的谐振频率点误差在10%以内,无功补偿量均满足现场试验需求,对今后的开关交流耐压试验和变压器局部放电试验等高压试验给出了理论依据。
Resonance is a phenomenon of reactive power balance circuit when capacitive equipment and perceptual equipment under the specific frequency, which is very common in power system applications and was more widely used in high voltage test. Based on basic principles of RLC resonance circuit, the paper analyzes the use of reso- nance /＇or high voltage withstand test in depth and the principle of the argument, and compares the high voltage test results. It concluded that the theoretical calculation of resonant frequency point error is within 10% , the amount of reactive power compensation meets the demand of field test, thus the guiding theory can be applied to high voltage test.
