Standard Construction Background
With the wide application of various types of generator units in distributed power supply, emergency power guarantee and mobile power supply scenarios, the supporting technical specifications for matched air circulation and heat dissipation systems are continuously supplemented and improved, forming a multi-dimensional standard constraint system covering design, production, test and installation links. The stable output of generator units is closely related to the operating temperature control of internal coils and power components. Excessive local temperature rise will directly lead to the decline of power supply efficiency, and even trigger the shutdown protection of the whole set of power equipment. In the absence of unified industry standards in the early stage, the design parameters of supporting ventilation equipment produced by different manufacturers are quite different, resulting in frequent matching failure when supporting different brands of generator units, bringing great hidden dangers to the stable operation of power supply projects. The improvement of the standard system has become an inevitable demand for the standardized development of the industry.
Core Index Constraint Requirements
The newly supplemented industrial standards put forward clear constraint requirements on multiple core indicators of supporting ventilation equipment, including uniform air supply range, continuous operation stability under full load, noise limit value and environmental protection material application specifications. For the air supply uniformity index, the standard makes clear provisions on the air volume deviation within the effective heat exchange range, requiring the air flow to fully cover all heat generating components, avoiding the problem of local overheating caused by uneven air distribution. For the continuous operation stability, the standard requires that the equipment can maintain stable performance after long-term continuous operation under rated working conditions, and there will be no obvious performance attenuation or structural failure. In addition, the standard also puts forward corresponding requirements for the operation noise of equipment, especially for generator units used in residential areas and commercial places, the noise index of supporting equipment must meet the relevant environmental protection requirements.
Test Verification System Improvement
Under the guidance of new standards, all manufacturers in the industry are accelerating the construction of standardized test laboratories to improve the product test and verification system. Manufacturers need to complete long-term aging test, high and low temperature cycle test and dust resistance test of finished supporting equipment before delivery, and provide complete test data reports as the basis for product factory delivery. For mobile generator units applied in field construction, communication base station backup power and other scenarios, the standard adds additional requirements on structural vibration resistance and shell anti-corrosion performance, and manufacturers need to add corresponding test links to simulate the impact of road transportation vibration and outdoor harsh environment on equipment performance. The improvement of test verification system not only ensures that the delivered products meet the standard requirements, but also accumulates a large number of actual test data for subsequent product optimization and upgrading.
Special Scene Standard Supplement
For different application scenarios of generator units, the industry standard also adds targeted supplementary provisions to meet the differentiated use requirements. For generator units used in outdoor mobile scenarios, the standard puts forward higher requirements for the volume, weight and structural strength of supporting ventilation equipment, so as to adapt to the needs of frequent transportation and transfer. For generator units used in underground and closed spaces, the standard focuses on the requirements of equipment sealing performance and exhaust gas isolation, to avoid the impact of circulating air mixed with impurities on the internal components of the generator set. For generator units used in plateau and high altitude areas, the standard supplements the performance correction requirements of supporting equipment under low air density environment, to ensure that the equipment can still provide sufficient heat exchange capacity under plateau environment. The refinement of these scene standards makes the standard system more applicable.
Industrial Chain Standardization Promotion
The improvement of the standard system also promotes the standardized construction of the whole industrial chain. Upstream raw material suppliers adjust the production formula of metal alloy and composite materials according to the standard index requirements, and develop special materials that meet the performance requirements of supporting ventilation equipment, so as to provide stable raw material support for downstream manufacturers. Downstream generator unit manufacturers form unified parameter matching specifications when selecting supporting ventilation equipment, which reduces the repeated debugging work in the assembly link and improves the production efficiency of the whole machine. The two-way constraint of upstream and downstream standards eliminates the information asymmetry in the procurement and matching link, reduces the repeated modification cost caused by mismatched parameters, and guides the whole industry to develop towards standardized, serialized and high-efficiency supporting equipment manufacturing.
Standard Development Prospect
With the continuous expansion of the application scope of generator units and the emergence of more new application scenarios, the industry standard system will continue to be updated and improved. In the future, the standard will further increase the requirements for energy efficiency and green performance of supporting equipment, guide the industry to reduce the energy consumption level of equipment on the premise of ensuring heat exchange performance, and respond to the call of green and low-carbon development. At the same time, the standard will also promote the serialization and generalization of supporting ventilation equipment, reduce the customized design cost through modular and universal design, and improve the supply efficiency of the industry. The continuous improvement of the standard system will continue to standardize the market competition order, promote the overall technical level of the industry, and provide strong support for the reliable operation of generator units in various scenarios.
