摘要
针对传统电能表接线排查中直接拉闸或利用有线信号进行判断的缺点,本文首次提出了一种使用无线信号进行串户分析的方案。该方案不仅可以提高排查效率,同时大大降低了对用户的影响。由于高频信号在传输过程中损耗大,易受现场复杂环境的干扰,不同用户之间难以区分。在传输线理论的基础上,对高频信号在电力线传输的损耗特点进行了详细的分析,并以此为基础,对该无线排查系统的理论模型进行验证。计算给出了该系统在不同环境下的有效判断范围。并最终通过实测数据进一步证实了该方案的可行性。
Switching out directly or judging by wired signal was the conventional method of checking meter wiring. A method which improves the efficiency of troubleshooting and greatly reduces the influence on users is presented by this paper for users of electricity using wireless signals for the first time. As the high-frequency signal in transmission process wastes largely and affected easily by complicated interference in the scene,it is difficult for different users to distinguish from. The loss characteristics of high frequency signal in power are analyzed in detail which based on the theory of power transmission line. Besides,the paper has verified the theoretical model of the wireless troubleshooting＇s system and calculated the effectively distinguishable range of system in different scenes.Ultimately,the feasibility of scheme is confirmed by the measured data.
