Choose a diesel generator with an automatic starting device. Once the city's power supply is interrupted, power must be supplied within 15 seconds (high regulations require 30 seconds). In Category II high-rise buildings, units equipped with automatic starting devices should also be used where conditions permit, and manual starting devices may also be used in case of difficulties.
7. Performance and quality must comply with relevant standards.
As a communication diesel generator set, it must meet the requirements of G3 or G4 level of GB2820-1997 and the 24 performance indicators stipulated in the “Implementation Rules for Certification of network quality and inspection of communication diesel generator sets. "
Flatness standards for foundation cushionswind turbines include flatness requirements, flatness measurement methods and standardized certification.
1. Flatness Requirements: The flatness of the foundation pad is the key to ensuring tightness and stability between the tower and the foundation during the installation process. The flatness error of foundations should generally be between a few millimeters and more than ten millimeters.
2. Flatness Measuring Method: Instruments such as theodolite, level or laser level are generally used to measure the flatness of the foundation pad. Placement of measurement points generally follows specific code requirements to ensure complete and accurate measurement of the entire pad surface.
3. Standardized certification: In some regions, such as the European Union and China, there may be specific standards and certification requirements to ensure quality and safety.tee of wind turbine foundation cushions. These standards may include ISO9001 quality management system certification and associated industry standards.
