In order to further promote the spirit of model workers and craftsmen, give full play to the leading role of model workers and craftsmen, and effectively increase the work of serving enterprises, on March 21st, the All Cities Federation of Trade Unions organized the voluntary service team of model workers and craftsmen in various cities to "send technology to enterprises", enter the large-scale activity, and carry out activities such as technical research and development, skill guidance, technical exchange, and volunteer service.

On the day of the event, Weifang craftsman Liu Yumin and technical personnel from the power supply company came to our company to answer questions and clarify their doubts about power supply safety knowledge. Regarding the regulations and daily precautions for safe electricity use, as well as the high damage rate of reactive power compensation capacitors in photovoltaic low-voltage grid connected systems, and the significant harmonic interference of the company's frequency converter and intermediate frequency heating equipment in the power grid, improvement ideas and solutions are provided. For problems that cannot be solved on the spot, the service team also stated that they will continue to follow up and solve them, and provide services to the end.
