适用范围
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.
