[Abstract]:Equipment supervision is an important link to guarantee the quality of equipment. In order to carry out the supervision work of installation stage of transmission and transformation project, combined with the supervision practice of 1000kV UHV AC transmission and transformation project. This paper deals with the supervision and control measures for the installation of 1000 kV transformers and the erection of steel pipe towers. The key links and the installation technology of 1100kV gas insulated combined electrical switchgear equipment (hereinafter referred to as GISs) based on mobile workshop are analyzed and summarized in depth. Through the supervision practice, the transformer is put forward. GIS installation supervision control standard, control points and inspection methods, and according to the characteristics of UHV installation, risk assessment and safety supervision summary. The construction safety risk assessment software of power transmission and transformation project has been developed, which is of great guiding significance and economic benefit to ensure the construction quality of the project. The main work and results of this paper are as follows: 1. Combined with the installation requirements and characteristics of 1000kV UHV transformer, the installation process of the transformer is optimized. This paper summarizes the supervision and control measures of the key links in the field installation of 1000kV transformers, and through the practice of installation supervision, puts forward the supervision control standards, control points and inspection methods for the installation of transformers. It ensures the installation quality of transformer and provides valuable experience for the field installation of 1000kV transformer. 2. The mobile factory building for the field installation of UHV G1S is developed. The GIS installation technology based on mobile workshop is formed, and the structure design scheme, sealing, environment detection and control scheme of mobile powerhouse based on single beam crane are formed. The application of mobile workshop makes GIS installation overcome the influence of external environment on the installation process, ensure the installation conditions of GIS equipment, realize factory installation, significantly improve the working environment of workers, and reduce the labor intensity. Through the practice of installation supervision, this paper puts forward the control standard, control points and inspection methods of GIS installation supervision, which ensures the installation quality. To improve the management level of project supervision. Applied to the 1000 kV UHV AC power transmission and transformation project in northern Zhejiang and Fuzhou, the effect is good, which ensures the construction period. 3. Combined with the practical characteristics of UHV steel pipe tower group. This paper probes into the methods and means of supervision and control in the process of steel pipe tower erection construction, and puts forward the key links and important control measures of supervision and control in the construction stage of steel pipe tower assembly. 4. According to the installation characteristics of ultra-high pressure equipment. Put forward the risk management suggestion, based on the safety risk assessment theory, developed the transmission and transformation power construction safety risk assessment software, realized the dynamic risk automatic evaluation calculation, is advantageous to the risk management document execution. It can effectively improve the fine level and work effect of construction risk management, and provide technical guarantee for safety supervision. Through the practice of safety supervision, the key points of safety supervision for installation of UHV equipment are summarized.
