적용 범위

This standard applies to arcing fault detectors installed in electrical circuits with a power capacity of 10kW and below in industrial and civil buildings. It covers both independent and non-independent detectors used in electrical fire monitoring systems. This standard is mandatory for manufacturers producing fire monitoring equipment for the Chinese market.

기술 요구 사항

The standard specifies comprehensive requirements for the operational performance and safety of the detectors. It mandates that detectors must reliably identify arcing faults within 30 seconds when specific thresholds of half-cycle arcs occur within 1 second, while ignoring non-hazardous arcs. Detectors must not trigger false alarms during normal load operations or electromagnetic interference. The standard also defines strict criteria for insulation resistance, dielectric strength, and leakage current to ensure electrical safety. Furthermore, it sets requirements for environmental endurance, ensuring the device functions correctly under extreme temperature, humidity, and mechanical stress conditions. Component-level requirements, such as the visibility of indicator lights and the minimum sound pressure level of audio alarms, are also clearly defined.

시험 방법

The standard outlines a series of rigorous tests to verify compliance, including arcing fault simulation using carbonized paths and metallic contact methods. It also includes false alarm tests using common household appliances like vacuum cleaners and microwave ovens. Environmental and mechanical tests, such as low-temperature operation, constant humidity, impact, and vibration, are conducted according to GB 16838. Additionally, electromagnetic compatibility (EMC) tests, referencing the GB/T 17626 series, are performed to ensure immunity to electrostatic discharge, radiated electromagnetic fields, and electrical fast transients.

자주 묻는 질문

What products are regulated under GB 14287.4-2014?

It applies to arcing fault detectors installed in electrical circuits of 10kW or less in industrial and civil buildings. It is specifically designed for electrical fire monitoring systems.

How does GB 14287.4-2014 differ from other parts of the GB 14287 series?

It focuses specifically on detecting arcing faults to prevent electrical fires, whereas other parts of the GB 14287 series address residual current or temperature monitoring. This standard mandates strict performance criteria to avoid false alarms from normal electrical loads.

Is compliance with GB 14287.4-2014 mandatory for market access in China?

Yes, Chapters 5, 7, and 8 are mandatory. Manufacturers must comply with these requirements to legally sell their electrical fire monitoring devices in the Chinese market.
