三段式电流保护原理解析
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。

柔性拖链电缆的选择需要考虑什么?
一、敷设条件。通常,屏蔽电缆用于具有抗电磁干扰的地方,柔性电缆主要用于移动设备。 二、机械强度。由于控制电缆本身的截面小,因此在工作过程中也有很高的可靠性要求。根据相关行业规定,选用的电缆大多属于铜芯电缆。在使用这种电缆时,必须合理地控制其直径。 三、负载能力。电缆工作时,电路中的电流和电阻及电压必须在规定范围内。当它连接到电流互感器的次级侧时,还需要检查横截面的相关性。如果它连接到变压器,则相应地检查其电压降。如果仪表用于测量回路,则必须根据仪表的测量精度进行调整,如果应用于计费仪表,则电压降应小于或等于额定电压的百分之五。对于自动装置,继电保护和控制回路,前两个不要大于百分之三,后者要0小于和等于百分之十。

分支电路导体的尺寸确定和保护
本文旨在确定为分支电路负载供电的导体的尺寸和保护。支路额定电流NEC 第 210 条规定了分支电路导体尺寸和过流保护的一般要求。允许额定电流或过流保护装置的设置确定了分支电路额定值 (210.18)。电路的安培额定值取决于保护导体的断路器或保险丝的额定值,而不取决于电路中导体的尺寸。
我想了解美国力特SE-135这个接地故障监测器产品,有以下问题需要咨询: 1、这个产品监测的线路电压允许范围是多少?例如10KV线路可用吗? 2、负载端需要安装的这个终端选用28还是45欧姆,使用有何区别?在有漏电情况下这个终端阻值是变为0吗?在不同电压线路的阻值变化是什么状态? 3、移动拖曳电缆实际使用工况中,电缆遇机械损伤等异常情况时,高电压有可能串入GC检测线上,这种情况监测器能正常工作不会损坏吧?
1.SE-135说明书并没有明确可以应用的电压范围,一般情况下是用于35KV以下系统,10KV是可以用的。SE-135说明书参考链接:SE-134C, SE-135 SERIES 2.终端组件的型号是SE-TA12A,并不是一个电阻,是一个齐纳特性终端,SE-135持续持续监测远方终端组件的齐纳特性,从而实现对拖曳电缆接地线完好性的持续监测。漏电一般指的是相电缆绝缘破坏,通过某种介质或者直接接地,比如A相接地故障。SE-135通过连接的电流互感器,可以实现接地故障保护。简单的说,SE-135有两个功能:接地故障保护和接地线监测3. 如果是感应的电压电流,一般没有问题,不会损坏装置和终端。如果串入高压,肯定会损坏装置。因为SE-135只是一个微机保护装置,不能承受高电压串入,可能会损坏终端或者保险丝熔断。
