Abstract

The invention relates to the technical field of electrical equipment detection and diagnosis, and particularly relates to method for asynchronous motor parameter and fault information mapping process.The method comprises the following steps: extracting a mapping relationship between asynchronous motor time axis voltage, random uncertainty of load in current signals and fault characterization characteristic parameters when multi-harmonic parameters are introduced into power supply dynamic adjustment based on static and dynamic mathematical models; proposing the relation between the distortionquantity in the time domain and the harmonic quantity in the frequency domain and the fault information is provided; and establishing an asynchronous motor operation process data mapping model capableof distinguishing motor body parameters, loads, power supply changes, fault parameters and fault conditions.

Description

technical field

[0001] The patent of the present invention relates to the technical field of detection and diagnosis of electrical equipment, in particular to a method for the mapping process of asynchronous motor parameters and fault information. Background technique

[0002] With the improvement of people's quality of life, some repeatable and cumbersome work processes will be replaced by real-time detection and self-diagnosis equipment. As a widely used and indispensable bottom-level motion actuator in industrial production, the degree of intelligence of the motor also directly reflects and affects the development process of industrial intelligence. At present, our country considers the problems of high shutdown cost, long maintenance cycle and large influence for high-voltage large-scale motors. Some temperature and vibration sensors are preset and pre-buried inside the motor when it leaves the factory. Changes in parameters to predict the operating conditions of the mo...
