Switching no-load Power line is one of the operating duties for circuit breaker.This PaPer gives statistical analysis of overvoltage results of field test on switching 500kV Gezhouba-Feng-huangshan no-load Power line.Test results show that when both Gezhouba and Fenghuangshan substatons are connected with shunt reactors, circuit breaker is restrike free.When the circuit breaker is equipped with closing resistance, overvoltage is loss than 1·3 times.

切合空载长线是断路器的基本功能之一。本文对葛凤线切合空载长线试验的过电压实测结果进行统计分析。试验结果表明:当线路首、末端均接入并联电抗器后,断路器分闸无重燃、复燃。采用100Ω合闸电阻后,合闸过电压不超过1.3倍。

When the nominal power, rated current and normal efficiency of a three-phase induction motor are known, and the no-load power and noload current under the constant network voltage, the loaded power in input and loaded stator current are determined, then the power output of the motor loaded can be calculated by the formula with error diminished within the allowance.

Only using the normal magnetizing curve (B-H curve) of the material for transformer core, its geometric dimensions, the no-load power loss data and the conception of instantaneous power, a new simulating method is presented in this paper. It enables to calculate the magnetizing inrush current occurring in case of switching on no-load transformer at different switching angles and different remanent flux. Based on the calculated results, such characteristics of the magnetizing inrush current are analyzed as the relationship of magnitude, waveform, discontinuous angle with respect to remanent flux and switching angles, etc. At last, the result of simulating calculation using EMTP for the same transformer is compared with that obtained by the method presented in this paper and the result of comparison shows that this method is helpful for verifying the correctness of power transformer design and for the research of new transformer protection principle, e. g., applying the neural network to transformer protection, etc.

本文提出一种基于变压器铁芯材料的基本磁化曲线B=f(H)、变压器铁芯的几何尺寸、空载损耗数值及瞬时功率的概念,对变压器空载合闸时,在各种不同的合闸角及各种不同剩磁的情况下所产生的励磁涌流进行计算的新方法。通过对计算结果的分析,得出励磁涌流的特征,如峰值、波形及间断角的大小同剩磁和合闸角的关系等。本文所提出的方法有助于对电力变压器设计的正确性进行校验及变压器保护的研究。
