Problems solved by technology

[0003] In the existing technology, when the industrial electrical frequency conversion equipment is running, when a failure or abnormal state occurs, we usually cannot know it in time, nor do we follow the equipment operation rules or observe the possible precursors, so as to carry out timely monitoring before the failure occurs. Forecast, for this reason, we propose a safety early warning system for industrial electrical frequency conversion equipment

Abstract

The invention discloses a safety early warning system for industrial electric appliance frequency conversion device, belongs to the field of industrial electric appliance frequency conversion devices, and is used for solving the problem that fault conditions and abnormal states cannot be early warned and monitored when the industrial electric appliance frequency conversion device operates. The safety early warning system comprises an early warning and monitoring module, a quality calculation module, an early warning and defining module and a data analysis module. The data analysis module is used for analyzing the working data of the frequency conversion device, the early warning and defining module is used for defining and judging the operation value of the frequency conversion device after receiving the operation value of the frequency conversion device, and the quality calculation module is used for calculating the quality of the frequency conversion device for generating a verification early warning signal and a monitoring early warning signal after receiving the verification early warning signal and the monitoring early warning signal. According to the system, the frequency conversion device is timely and effectively monitored and diagnosed through a state monitoring technology, the abnormal condition of the device is timely forecasted before the device breaks down, and the safety and stability of production are ensured.

Description

technical field [0001] The invention belongs to the field of frequency conversion of industrial electrical appliances, and relates to safety early warning technology, in particular to a safety early warning system for frequency conversion equipment of industrial electrical appliances. Background technique [0002] The frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply. The frequency converter is mainly composed of rectification, filtering, inverter, braking unit, drive unit, detection unit and micro-processing The inverter is composed of internal IGBTs to adjust the voltage and frequency of the output power supply, and provides the required power supply voltage according to the actual needs of the motor, so as to achieve the purpose of energy saving and speed regulation. In addition, there are many inverters Protection fun...
