Problems solved by technology

However, this way of observing the waveform through the oscilloscope needs to use cables to transmit the data of the sensor to the oscilloscope, and this also causes secondary wiring at the user site, which affects the debugging efficiency of the converter
At the same time, the observation channels of the oscilloscope are limited. If there are many physical quantities to be observed, multiple oscilloscopes may be needed
In addition, due to the relatively large size of the oscilloscope, it is also inconvenient to carry

Abstract

The invention discloses a current transformer waveform monitoring device and a current transformer control system. The monitoring device comprises a data acquisition module which acquires current transformer operation state related data required to be monitored in each operation cycle of a current transformer control algorithm according to the current transformer control algorithm so that monitoring data are obtained; a data acquisition module which is connected with the data acquisition module and used for converting the monitoring data according to the preset communication protocol; and a data display module which is connected with the data transmission module and used for visually displaying the data transmitted by the data transmission module so that current transformer waveform monitoring is realized. Compared with existing waveform monitoring devices, the device is high in real-time performance, and waveform of voltage and current outputted by the current transformer can be monitored in real time. Other hardware equipment does not need to be carried by debugging personnel when the waveform of the current transformer is monitored.

Description

technical field [0001] The invention relates to the technical field of automatic detection, in particular to a converter waveform monitoring device and a converter control system. Background technique [0002] During the debugging of the converter, it is necessary to observe the waveforms of physical quantities such as current, voltage, and rotational speed at the load terminal in real time, so as to adjust the parameters of the converter according to these waveforms, so that the performance of the converter can meet the actual needs of users. [0003] At present, monitoring the waveforms of physical quantities such as voltage, current, and rotational speed at the load end of the converter mainly adopts an oscilloscope to observe the waveforms of physical quantities converted by sensors. However, this method of observing the waveform through the oscilloscope requires the use of cables to transmit the sensor data to the oscilloscope, which also results in secondary wiring at ...
