Generators refer to mechanical equipment that converts other forms of energy into electrical energy. They are driven by water turbines, steam turbines, diesel engines, or other power machinery, which convert the energy generated by water flow, airflow, fuel combustion, or nuclear fission into mechanical energy and transmit it to the generator, which then converts it into electrical energy Generators have a wide range of applications in industrial and agricultural production, national defense, technology, and daily life. There are many forms of generators, but their working principles are based on the laws of electromagnetic induction and electromagnetic force. Therefore, the general principle of its construction is to use appropriate magnetic and conductive materials to form a magnetic circuit and circuit for mutual electromagnetic induction, in order to generate electromagnetic power and achieve the purpose of energy conversion
Testing standards for generators: AQ 1075-2009: General technical conditions for AC generator sets driven by low concentration gas reciprocating internal combustion engines in coal mines AS 2790-1989: Portable generator sets (maximum 25 kW) Revision 1: ASTM A288-1991 (2008) in December 1989 Specification for carbon and alloy steel forgings for magnetic retaining rings of turbo generators BS 4999-140-1987: General requirements for rotating electrical machines Part 140: Voltage regulation and parallel operation specifications for AC synchronous generators BS 5000-3-2006: Special or specialized rotating electrical machines Part 3: Generators driven by reciprocating internal combustion engines
Why do enterprises need third-party testing? Product research and development: component analysis, analysis of component proportions, improvement of production defects, improvement of product quality and performance. Government regulation: industrial and commercial testing, market supervision, project bidding, application for tax refund funds, and other listed quality control measures: ensure that one's products can smoothly enter various electronic product platforms, supermarkets, and other markets, enhance the cognitive credibility of enterprises, expand market share, and enhance their competitiveness, Industrial diagnosis for demonstrating product quality: providing you with qualitative and quantitative analysis services for unknown substances in processes and materials
Function of testing report:
