Problems solved by technology
[0004] Most inverters have multiple self-protections such as overvoltage, overcurrent, and overheating. Any self-protection trigger will cause the inverter to stop working.
However, when the self-protection starts, some functional units in the inverter will often be damaged due to instantaneous overvoltage, overcurrent or overheating, and it will take time to repair, which will cause the inverter to be unable to work for a certain period of time, causing serious damage to production and life. influences

Embodiment Construction
[0046] Attached to the following Figure 1-5 This application will be described in further detail.
[0047] The embodiment of the present application discloses an intelligent monitoring method for a frequency converter, see figure 1 , figure 2 , including the following steps:
[0048] In step S1, the working parameters of each functional unit are acquired, and the working parameters are values such as voltage parameters, current parameters, and temperature parameters generated by the corresponding functional units during actual operation.
[0049] The frequency converter is composed of multiple functional units such as rectifier unit, filter unit, inverter unit, braking unit and drive unit. The smallest unit in the functional unit is an electrical component, and the number and types of electrical components that constitute different functional units are often different, and different electrical components can withstand different voltages, currents, and temperatures. vol...

The present application relates to an inverter intelligent monitoring system and an intelligent monitoring method, comprising the following steps: obtaining working parameters of each functional unit; obtaining warning parameters of each functional unit; If the parameter exceeds the warning parameter, an alarm signal is sent, and the warning signal includes the label corresponding to the functional unit whose working parameter exceeds the warning parameter. Electric energy will have different states in different functional units in the inverter. Set the corresponding warning parameters for each functional unit, and collect the actual working parameters of each functional unit for comparison, so as to intuitively know whether the working state of each functional unit is Normal, more accurate monitoring of the inverter.
Description
technical field [0001] The present application relates to the field of inverter monitoring, and in particular, to an inverter intelligent monitoring system and an intelligent monitoring method. Background technique [0002] With the continuous improvement of industrial automation, frequency converters have been widely used. [0003] The frequency converter is mainly composed of multiple functional units such as rectifier unit, filter unit, inverter unit, braking unit and drive unit. [0004] Most inverters have various self-protections such as overvoltage, overcurrent, and overheating, and the triggering of any kind of self-protection will cause the inverter to stop working. However, when the self-protection is started, some functional units in the inverter are often damaged due to instantaneous overvoltage, overcurrent or overheating, and it takes time to repair. influences. SUMMARY OF THE INVENTION [0005] In order to reduce the possibility of sudden failure of the f...
