三段式电流保护是一种广泛应用于电力系统的保护策略，主要用于保护发电机、变压器和输电线路等设备。其基本原理是通过设定不同的电流保护等级，在发生故障时及时切断电源，以防止设备损坏。以下是三段式电流保护的基本原理及各段的详细介绍：

1. 基本原理

三段式电流保护根据故障的性质和发生地点，将电流保护分为三个阶段或段落（也称为“保护段”）进行监测和响应。每个阶段都有不同的响应时间和动作条件，通常为：

第一段（短路保护）：用于快速检测大故障（如短路），以便在短时间内切断故障电路。

第二段（过载保护）：用于监测设备的过载情况，通常会有一定的延时，以避免误动作。

第三段（长期过流保护）：用于监测较小的过载情况或长期运行时的过流状态。

2. 各段详细介绍

第一段：短路保护

原理：主要检测故障电流（如短路电流），当电流超过设定值时，立即动作。

动作时间：响应时间极短（通常为毫秒级），以迅速切断故障电源，防止设备损坏。

应用：适用于高压系统、低压系统中的瞬时短路故障，保护发电机和变压器等设备。

第二段：过载保护

原理：检测设备的过载电流，通常设定一个较高的电流阈值，并在一段时间内持续监测。

动作时间：有一定的延时（几秒到几十秒），以防止因暂时性过载（如启动时的瞬时电流）导致误动作。

应用：适用于长时间运行的电流，保护电动机和变压器等设备。

第三段：长期过流保护

原理：监测长期存在的过流情况，通常用于设备在正常运行情况下的电流监测。

动作时间：延时较长（可能为几分钟），以防止由于负载波动而误动作。

应用：适用于需要长时间监测的负载，例如电动机在不同负载下的稳定运行。

3. 保护逻辑

协调性：三段式电流保护在设计时需要确保各段保护之间的协调，避免重叠保护导致的误动作。

选择性：通过合理设定各段的动作参数，确保在故障发生时只有接近故障点的保护段动作，从而减少对整个系统的影响。

自检与测试：电流保护装置通常具备自检功能，能够定期检查其功能和准确性，以确保在故障发生时能够及时响应。

B系列热链（ATCO）-合金型

描述- ATCO（Alloy Thermal Cutoff）是一种一次性不可重置的保护装置，广泛应用于电气设备中。它主要由熔融合金、焊剂树脂、外壳、密封剂和引线组成。当温度达到ATCO的熔化温度时，熔融合金会熔化并迅速收缩，通过焊剂树脂的作用与引线断开，完全切断电路。B系列ATCO的额定工作温度范围为76℃至221℃，额定电流为3A，具有非重置性、高精度工作温度和符合RoHS和REACH标准的特点。
