At the beginning of 2000, after he retired from the army and entered the company, Lei Peng realized that he could not solve specific problems by his own enthusiasm and endless work enthusiasm. When he goes to work during the day, he is thirsty for knowledge while working with the master. He writes down the structure and principle of the equipment in his notebook, records the original data of the equipment, and records the main points and experiences of maintenance. Whenever in doubt, he asked the master again and again. After work, he rushed to professional schools, absorbed the nutrition of cultural knowledge and was busy "charging" himself. After several years' efforts, Lei Peng has obtained a junior college degree, and the maintenance technology has made a qualitative leap. In one fell swoop, he won the senior salary certificate of "motor maintenance" and "maintenance electrician" and won the first place in the motor assembly technology competition organized by the motor professional company. In the overhaul of 900,000 ultra-supercritical units in Waigaoqiao No.2 Power Plant in 2009, he was recognized by the leaders for his skilled and standardized overhaul technology and diligent and practical work style, and was named as an advanced individual in the unit overhaul labor competition. In 2065+00 1 wanchao supercritical unit overhaul of Waigaoqiao No.3 power plant, it was highly praised by power plant electrical professionals.
