269PLUS-DO-211-100N-120VAC 在其硬件极限附近运行
【产品详情】
269PLUS-DO-211-100N-120VAC是269 Plus电机管理继电器系列的电机保护系统,由GE Multilin生产。这种基于微处理器的保护系统设计用于与三相电机一起使用,因为它们在其硬件极限附近运行。该保护系统可以监测和控制所附电机在加速和运行/稳态条件下的状态。这个继电器是保护系统的加长版。它有相位和接地电流互感器(CTs)分别为2:5和2:5。该系统还具有100欧姆镍电阻热检测器(RTD)。该型号的控制电压为120vac。
这种电机保护系统能够在运行时提供关键的热效应保护。系统通过使用RTD监控来做到这一点。然后,系统能够基于相关的热容量执行热建模。保护系统使用指数冷却来匹配实际电机的冷却速率。由于系统的急剧初始冷却,继电器可以获得更高的负载循环。保护系统的关键输入有速度开关输入、差动继电器输入和备用输入。所述速度开关输入允许利用外部速度装置。差动继电器输入使操作人员能够关闭外部差动继电器的触点。备用输入,可配置为标准或自定义触点输入,允许识别断路器状态。

【英文介绍】
269PLUS-DO-211-100N-120VAC is a motor protection system from the 269 Plus Motor Management Relay series, produced by GE Multilin. This microprocessor-based protection system is designed to be used in conjunction with 3-phase motors as they are operated near their hardware limits. This protection system can monitor and control the condition of the attached motor in both accelerated and running/steady state conditions. This relay is the drawout version of the protection system. It has Phase and Ground Current Transformers (CTs) of 2:5 and 2:5 respectively. This system also has a 100 ohm nickel resistance thermal detector (RTD). The control voltage for this model is 120 VAC.
This motor protection system is able to provide critical protection from thermal effects while in operation. The system does this by using RTD monitoring. The system is then able to perform thermal modeling based on the associated thermal capacity. The protection system uses exponential cooldown to match the cooling rates of the actual motor. Due to the steep initial cooling of the system, the relay can attain a higher load cycling. The key inputs of the protection system are the speed switch input, the differential relay input, and the spare input. The speed switch input allows for an external speed device to be utilized. The differential relay input gives the operator the ability to close the contacts from an external differential relay. The spare input, which can be configured for either a standard or custom contact input, allows for identification of the circuit breaker condition.
