In view of the common multiple quality common problems existing in substation construction, the following rectification and prevention suggestions are proposed: Fibre Termination,Cable Termination Tool,Coax Termination,Battery Cable Wire Changshu Herun Import & Export Co.,Ltd , https://www.herunchina.com
(1) Starting from the source, strictly control the quality acceptance of the approach equipment, and strengthen the design depth and review strength of the design drawings. Strictly check the acceptance of equipment such as brackets and screen cabinets, and find out and eliminate existing problems in time. Regarding the technical problems of the equipment, the specific allowable values ​​must be stated in the ordering agreement. To reduce the inconsistency of standards when accepting acceptance: Strengthen the design depth of design drawings, reduce design changes, and strengthen the cooperation between design professionals to prevent omission and standardization of grounding of secondary equipment. (2) Strengthen process control, improve the quality awareness of construction workers, and make them familiar with the provisions of the electrical codes and regulations, and strengthen understanding and digestion. In the construction process, strict implementation of the regulations and strict construction according to the design drawings; in the construction process, the implementation of technological innovation. (3) Design and manufacturers should attach great importance to the isolation problem on the terminal block. In the product design, the isolation of AC and DC terminals, positive and negative power terminals, different control loops, etc. must be performed to control such problems from the source. In the process of construction and acceptance, it is necessary to find the phenomenon of non-isolation in time. If there are conditions, use empty terminals for isolation. If there are no empty terminals, increase the insulation spacers for isolation.
(4) Improve the laying, finishing and secondary wiring of cables, promote technical competition, strengthen the responsibility assessment system, and fully mobilize the enthusiasm of construction workers for careful construction and active innovation. Cable nameplates, lashings, and cable plugging must be rigorously programmed to check against each other in order to effectively avoid omissions and errors. (5) Strengthen the fineness of equipment installation adjustment and carefully debug. (6) Strengthen the supervision function of the on-site supervision unit. Through the on-site supervision, inspection, spot check and quality report of the supervision unit, the quality behavior of the construction unit shall be constrained and the construction quality shall be standardized. (7) Strengthen the three-level acceptance system within the construction unit to detect and eliminate defects in a timely manner. The implementation of pre-acceptance of project completion is indeed to ensure that the quality of the project is eliminated before the project is put into production, laying a solid foundation for the safe and reliable operation of the substation.
As the construction of substations continues to increase, in the construction of substations, as a supervising unit, it is necessary to promptly propose rectification measures for problems arising in the electrical installation process, and at the same time continue to increase supervision to ensure the quality of the project.
