Motor protection system

Abstract

The invention relates to a motor protection system, comprising a mechanical fault monitoring unit for performing mechanical fault monitoring on a motor and outputting mechanical fault monitoring data;and a motor protection controller for performing electrical fault monitoring on the motor and outputting a control command according to whether the electrical fault monitoring data and the mechanicalfault monitoring data are abnormal so as to achieve trip protection of the motor. According to the invention, with an embedded wireless IoT communication module, the motor protection system collectsmechanical vibration fault conditions measured and monitored by the mechanical fault monitoring unit in real time by using an IoT wireless communication method, thereby improving the comprehensive protection of the motor protection controller for the motor and improving the reliability of the motor application, can improve the servicing and maintenance time limit of motor equipment through remotereal-time understanding of working conditions of the electrical performance and mechanical performance of the motor on site, meanwhile can eliminate motor fault hazards, can avoid the occurrence of accidents, and is capable of centralized management of the reliable operation of the motor.

Description

technical field [0001] The invention relates to the field of motors, in particular to a motor protection system. Background technique [0002] In the application of industrial motor drag control, 40% of motor failures in practical applications are caused by electrical failures, and as high as 60% of motor failures are caused by mechanical failures. The current motor protection controller is mainly used for electrical protection and cannot be used for mechanical Protection and monitoring of heat generation, vibration, displacement, noise and power consumption caused by vibration faults. According to statistics, more than half of unplanned shutdowns are caused by mechanical failures. Many factors affect the service life of motors. When the earliest signs of failures occur, the equipment can work for several months before completely shutting down, causing very serious problems in the actual production process. Big loss. Contents of the invention [0003] The embodiment of t...
