电动机保护器

GY201采用进口集成电路和知识产权专利技术、软件著作权生产的全方位电动机智能监控保护器。由微处理器来执行电机保护和控制，并支持馈线保护，完成对电机操作、自诊断以及与上位机的通讯等,为电动机提供了测量保护，避免了因电动机过载、堵转、过压、欠压、轻载、断相、三相不平衡、接地等故障导致的生产事故，*大限度地保证设备正常运行的有效安全。

GY201is a series of all-round intelligent motor protector which imports IC, intellectual property patented technology and the software copyright production.GY201 adopts the microprocessor to execute the motor protection and control, and support the feeder protection, complete the motor operation, self-diagnosis and communication with PC, etc. It provides measurement for motor protection to avoid the production accidents because of motor overload, locked-rotor, overvoltage, undervoltage, light load, open phase, three-phase imbalance, grounding failure, to ensure the normal operation of the equipment.

本微机监控保护器是对电动机运行过程中的各种运行信息数据进行采集、运算、分析、监控、报警、控制的综合性的装置。装置通过对故障报警，保护动作（保护脱扣）以及利用动作延时时间的设定来实现即时准确的保护，保证生产的安全。还可以通过数据信息通讯，实现电动机运行状况的纤细信息在上位机上进行实时监测，并经计算机数据处理提供管理信息。在设备可能产生重大故障前，越限报警可及时提醒管理人员进行处理，避免了不必要的停机而对正常生产造成影响，*大限度地保证设备运行和控制的有效性。当电动机运行参数达到预设的预警值时，保护装置仅进行预警，不触发脱扣；但当越限值达到预置的脱扣值时，保护装置进入脱扣触发延时。在预置脱扣延时时间内若设备恢复正常运行，则取消脱扣执行；而如果超过延时时限，则保护装置发出脱扣信号驱动执行元件动作，断开电源停止电动机运行。在电动机控制装置实现各项保护功能的同时，各种保护信息也由装置生成并经通信接口上送至计算机管理系统。

This microcomputer monitoring protector is a comprehensive device for collecting, calculating, analyzing, monitoring, alarming and controlling of various running information data in the operation of the motor. The device can provide immediate and accurate protection and ensure the safety of the production by means of alarm, protection action (protection of unbuckle) and the setting of time-delay time. The device can carry out real time monitoring on the upper computer about the slim information of the motor running condition through the data communication and provide the management information by computer data processing. The limit alarm can timely remind administrative staff to deal before a significant fault may happen, which can avoid the unnecessary downtime or affect the normal production, to ensure effectiveness of operation and control to the maximum. When the motor running parameter reaches the preset warning value, the protective device only has the warning, and does not trigger the tripping; But when the limit reaches the preset value, the protection device enters the trip trigger delay. If the device returns to normal operation in the preset trip time delay, the trip will be canceled. If the delay time limit is exceeded, the protective device will emit a trip signal to drive the action of the element, and disconnect the power to stop the motor running. While the motor control device provides various protection functions, various protection information is also sent to the computer management system via the device generation and communication interface.
