The invention discloses an improved detection method of a star-sealing contactor for an elevator, which is applied to an elevator control system and is characterized in that a star-sealing loop comprises a frequency converter, the star-sealing contactor and an elevator host, and the frequency converter is connected with the elevator host provided with the star-sealing contactor; the detection method for the star sealing contactor for the elevator comprises the steps that the elevator is in a brake-releasing and car-sliding state, electronic star sealing and contactor star sealing act together, and the detection result of a star sealing loop of the contactor is determined based on current information fed back by a frequency converter. According to the detection method, due to the fact that the electronic sealing star exists all the time in the vehicle sliding state, even if a contactor sealing star loop is abnormal, the vehicle sliding speed is very low, the vehicle sliding distance is short, safety risks do not exist, and the detection time is short.

    本发明公开的一种改进的电梯用封星接触器检测方法,其应用于电梯控制系统,其特征在于:封星回路包括变频器、封星接触器和电梯主机,所述变频器连接配置有所述封星接触器的所述电梯主机;所述电梯用封星接触器检测方法包括使电梯处于松闸溜车状态且电子封星和接触器封星共同作用,基于变频器反馈的电流信息,确定接触器封星回路检测结果。本发明的检测方法,由于在溜车状态中,电子封星一直存在,即使接触器封星回路异常,其溜车的速度很低,溜车的距离较短,不存在安全风险,检测时间较短。
