369-C100 电机保护系统

369-C100是一款电机保护系统是一种为电动机提供全面保护的系统。其主要功能是在电机出现过载、缺相、堵转、短路、过压、欠压、漏电、三相不平衡、过热、轴承磨损、定转子偏心等故障时，进行报警或保护，从而确保电机的安全运行和延长使用寿命。

369-C100通常由电机保护器实现，这些保护器包括热继电器、电子式保护器和智能型保护器等多种类型。大型和重要电机一般采用智能性保护装置，这种装置能提供更精确、更快速的故障检测和响应。

此外，369-C100利用先进的技术进行故障检测。例如，利用电机气隙磁场进行电机偏心检测技术，可以实时在线监测电机的磨损状态，并通过曲线显示电机偏心程度的变化趋势，从而早期发现轴承磨损和走内圆、走外圆等故障，做到早发现、早处理，避免扫膛事故发生。

在短路保护方面，电机保护系统会检测电动机A、B、C三相线电流，当在一定时限内检测到三相最大电流超过电动机额定线电流的K倍（K为短路过流倍数，一般取8~10）时，即认为电动机有短路故障，进行速断保护。

总的来说，369-C100是一个复杂而重要的系统，它通过综合运用多种保护技术和手段，为电机的安全运行提供了坚实的保障。如需了解更多关于电机保护系统的信息，建议查阅相关文献资料或咨询电机保护领域的专家。

369-C100 电机保护系统

The 369-C100 is a motor protection system that provides complete protection for electric motors. Its main function is to alarm or protect the motor when overload, lack of phase, blocking, short circuit, overvoltage, undervoltage, leakage, three-phase imbalance, overheating, bearing wear, fixed rotor eccentricity and other failures, so as to ensure the safe operation of the motor and extend the service life.

The 369-C100 is usually implemented by motor protectors, which include thermal relays, electronic protectors, and intelligent protectors. Large and important motors generally use intelligent protection devices, which can provide more accurate and faster fault detection and response.

In addition, the 369-C100 utilizes advanced technology for fault detection. For example, the use of motor air gap magnetic field for motor eccentricity detection technology can monitor the wear state of the motor online in real time, and show the change trend of the degree of motor eccentricity through the curve, so as to detect bearing wear and faults such as inner circle and outer circle early, so that early detection and early treatment can avoid the occurrence of sweeping accidents.

In terms of short-circuit protection, the motor protection system will detect the motor A, B, C three-phase line current, when the three-phase maximum current detected within a certain time limit exceeds the rated line current of the motor K times (K is the short-circuit overcurrent multiple, generally 8~10), that is, the motor has a short-circuit fault, quick break protection.

Overall, the 369-C100 is a complex and important system, which provides a solid guarantee for the safe operation of the motor by integrating a variety of protection technologies and means. For more information about motor protection systems, it is recommended to consult the relevant literature or consult experts in the field of motor protection.
