Communication power supply equipment certification implementation rules: These implementation rules apply to voluntary product certification of communication power supply equipment applied by organizations to the Telecommunications Certification Center (TLC). The communication power supply equipment in these rules includes: high-frequency switching power supply, high-frequency switching rectifier, communication uninterruptible power supply (UPS), DC-DC conversion equipment, DC-DC module power supply, inverter equipment, AC voltage stabilizer, DC power distribution cabinet, diesel generator set, gas turbine generator set, gasoline generator set, AC power distribution equipment, DC power distribution equipment, and solar power supply combination power supply. 4.2.2.1 Testing standard……JB/T 10304-2001 \"Technical conditions for industrial frequency gasoline generator sets\" 4.2.2.2.15 Gasoline generator sets The initial certification and re-evaluation type test of gasoline generator sets should test the following items specified in JB/T 10304-2001 standard: Starting requirements B Voltage setting range (optional) C Steady-state voltage deviation B Transient voltage deviation and voltage recovery time B Voltage imbalance (when outputting three phases) B Frequency drop B Steady-state frequency band B Transient frequency difference and frequency recovery time B Cold and hot voltage changes B Line voltage waveform sinusoidal distortion rate B Line voltage deviation under asymmetric load (when outputting three phases) B Noise C Fuel consumption rate B Oil consumption rate C Check sealing C Grounding check B Insulation resistance C Withstand voltage B Phase sequence (when outputting three phases) B Check short-circuit protection function B Appearance quality C The supervisory inspection of gasoline generator sets only tests JB/T The following items specified in the 10304-2001 standard: Starting performance B Voltage setting range (optional) C Steady-state voltage deviation B Transient voltage deviation and voltage recovery time B Voltage imbalance (when outputting three phases) B Frequency drop B Steady-state frequency band B Transient frequency difference and frequency recovery time B Cold and hot voltage changes B Line voltage waveform sinusoidal distortion rate B Line voltage deviation under asymmetrical load (when outputting three phases) B Insulation resistance C Short circuit protection function B These implementation rules apply to voluntary product certification of communication power supply equipment applied by organizations to the Taier Certification Center (TLC). The communication power supply equipment in these rules includes: high-frequency switching power supply, high-frequency switching rectifier, communication uninterruptible power supply (UPS), DC-DC conversion equipment, DC-DC module power supply, inverter equipment, AC voltage stabilizer, DC power distribution cabinet, diesel generator set, gas turbine generator set, gasoline generator set, AC power distribution equipment, DC power distribution equipment, and solar power supply combination power supply.
