About the interference of electronic belt weigher, I have a few small experiences to share with you, which can be used as a reference for the on-site operators of electronic belt weigher and for the equipment commissioning site and operation process. There will be interference when there is electricity, which is a scientific law and cannot be avoided. What we need to do is how to avoid interference and reduce the interference to the acceptable range of our electronic belt weigher.
Two aspects can be considered: one is to reduce the interference degree of interference sources, and the other is to improve the anti-interference capability of equipment. As far as the belt scale is concerned, the interference sources are generally power supply interference and frequency converter interference. The possibility of power supply interference is very small. Our usual treatment is to connect a large circle of copper wire on the live wire of the power line, and then try to change a phase wire. The interference encountered at ordinary times comes from many frequency converters, which are the interference sources encountered in the operation of the belt weigher. Generally, four measures are taken. First, the special frequency converter for electronic belt weigher with excellent anti-interference performance is selected, which is the prerequisite. The second is to adjust the carrier frequency of the frequency converter and reduce the carrier frequency parameter to. The third is to connect the input end and output end of the frequency converter with anti-interference coils. The fourth is to reprocess the grounding wire of the frequency converter to ensure that the grounding of the frequency converter is in good condition.
The above is a brief introduction of the belt weigher manufacturer about improving the anti-interference ability of the equipment. The following aspects should be considered: one is to improve the interference ability of the control instrument, the supporting quality of the control instrument is good and the anti-interference ability has been tested through practice; the other is that the grounding measures of the electrical control cabinet must be in place, and the grounding measures of the weighing sensor must be in place, To put it bluntly, the anti-interference performance of the instrument and the equipment grounding are the key.
