Abstract: Combined with a lot of practice, there are many reasons that will affect the normal operation of electrical equipment in power supply and distribution engineering, and the application of electrical equipment installation and debugging technology is one of the important factors. The level of electrical equipment installation and debugging technology and its application according to local conditions can ensure the engineering quality and effectively improve the probability of normal operation of equipment. In order to apply the electrical equipment installation and debugging technology in the power supply and distribution projects with limited environmental conditions such as suburban or tourist attractions, combined with the actual combat, the application of installation and debugging technology is deeply summarized, which is of great significance to the quality assurance of power supply and distribution projects and the wide application of electrical equipment installation and debugging technology.
