Wiring phase sequence misconnection judgment method and alarm circuit thereof

The invention provides a wiring phase sequence misconnection judgment method and an alarm circuit thereof in order to solve the problem that whether wiring is correct or not is not reliable in the prior art. Comprising the steps that a detection processing circuit carries out voltage collection at a bypass access point part in a bypass device, a misconnection judgment module circuit carries out certain conditioning on collected voltage signals, the conditioned voltage signals are sent to an AD part of a DSP processor, and the DSP processor carries out algorithm processing. According to the invention, for the voltage detection of the access point, the wiring correctness of the bypass circuit is judged by adopting a hardware circuit, amplitude detection and time domain discrimination fusion method, so that the accuracy is ensured. 本发明为了解决现有技术判断接线正确与否不可靠的问题，提供了一种接线相序错接判断方法及其报警电路，包括检测处理电路在旁路装置中的旁路接入点部分进行电压采集、错接判断模块电路对采集到的电压信号进行一定调理、调理后的电压信号送入DSP处理器的AD部分、DSP处理器进行算法处理。本发明对接入点电压检测，采用硬件电路、幅值检测与时域判别相融合的方法进行旁路电路接线正确性的判
