LGJQ-400型导线过载能力的现场试验研究

The field test of the over loading capacity for the type of LGJQ-400 transmission line

为掌握输电线路采用LGJQ-400型导线的实际过载能力,以便给系统在n-1和n-2等事故或其他不利工况下的调度提供科学依据,确保系统和线路的安全稳定运行,特开展了LGJQ-400型导线的现场过载能力试验。试验结果表明,在实际运行环境中,LGJQ-400型导线具备较强的过载能力。

In order to get the practical over loading capacity of the type of LGJQ-400 transmission line, provides the scientific basis for the dispatching under the accident and unfavourable situation of n-1 and n-2 system mode, ensures safe and steady operation of the system and the power line, so carries out the field test of the overloading capacity for the type of LGJQ-400 transmission line. The results show that the type of LGJQ-400 transmission line has stronger overloading capacity under the practical operating environment.
