The invention relates to an elevator power supply protection method. The method comprises the following steps that an elevator power supply is divided into a first-level power supply and a second-level power supply, and the importance level of the first-level power supply is higher than that of the second-level power supply; the output state of the first-level power supply and the output state ofthe second-level power supply are detected; and the first-level power supply with the abnormal output state and/or the second-level power supply with the abnormal output state are cut off according tothe output state of the first-level power supply and the output state of the second-level power supply, and different levels of processing responses are started. Therefore, according to the elevatorpower supply protection method, when a certain level of power supply has output abnormality, only the level of power supply with the output abnormality is cut off, the corresponding processing response is started, and different levels of processing responses are adopted according to different output abnormality conditions, so that the output of the elevator power supply is prevented from being directly stopped when the output is abnormal, and the emergency stop trapping probability of the elevator is reduced.

    本申请涉及一种电梯电源保护方法,通过将电梯电源划分为第一等级电源和第二等级电源,第一等级电源的重要等级高于第二等级电源。检测第一等级电源的输出状态和第二等级电源的输出状态,并根据第一等级电源的输出状态和第二等级电源的输出状态,切断输出状态异常的第一等级电源和/或输出状态异常的第二等级电源,启动不同等级的处理响应。因此,本申请提供的电梯电源保护方法,可以在某一等级电源存在输出异常时,仅切断存在输出异常的等级电源,并启动相应的处理响应,针对不同输出异常情况采用不同等级的处理响应,从而避免发生输出异常时直接停止所述电梯电源的输出,减少电梯急停困人几率。
