AFDD by professional people Members of household and similar installation in order to reduce its lower electrical fire hazard. Of well-known, residual current protection device (RCD) can be caused by the leakage current and the tracking of the electrical current sensing apparatus of Arcing and to reduce fire hazard. But in fact RCD, fuse or miniature circuit breaker (MCB) can not be reduced between the live conductors The series arc or parallel arc caused by electrical fire hazard. When the series arc fault occur, due to not produce earth leakage current, thus RCD can not detect such failures. And the series Arc fault impedance reduces the load current, so that the current is less than MCB or fuse trip threshold. Between the phase and neutral conductors Parallel arc generated when the current is limited only by the impedance means. The most serious cases are sporadic arc, and not for the traditional circuit breaker It designed for this purpose. Practical experience and existing information confirms that the fire caused by the rms value of the earth fault current is not limited to the rated power of 50/60Hz Source frequency, high frequency spectrum may include test RCD is not considered. Has recognized the risk of electrical fire inside the device may be the result of over-voltage three-phase electrical installations neutral disconnection caused. This standard includes a specialized installation in AFDD terminal circuit line side means one or more fixed electrical distribution board. Electric arc fault protection (AFDD) General requirements1 ScopeThis standard applies to electrical arc fault protection for household and similar purposes AC circuit, hereinafter referred to AFDD. This standard specifies the AFDD technical requirements and test procedures. Note 1. AFDD similar to the US AFCI "arc fault circuit breaker." AFDD designed by the manufacturer. --- Having a single device disconnect mechanism, capable of disconnecting the protected circuit under specified conditions; or --- As a single device and protection of electrical grouped together; or --- As an independent unit, in accordance with Appendix D and declared protection of electrical field assembly. The combined electrical protection should be consistent with GB 10963.1-2005 circuit breaker or in compliance with GB 16916.1-2014, GB 16917.1- 2014, GB 22794-2008 residual current protection device (RCD). Under certain conditions, if sustained arcing due to an arc fault current will cause a fire hazard. These devices are expected to reduce fixed Fire hazard electrical apparatus terminal circuit. Over-voltage three-phase electrical installations neutral disconnection caused the fire causing, such devices can also be used to protect, as an additional Selection, see 9.22. Note 2. The tracking of the current caused by arcing, which could cause a fire. This standard applies under specified conditions can be performed to detect arcing current, arc current and the fire moves more dangerous and when the value of the fuel Circuit protection by means functions such as arc current interruption exceeds the action value. AFDD complying with this standard for IT systems, with the exception of not disconnect the neutral line AFDD. The maximum rated voltage not exceeding 240V. Compliance with this standard AFDD is powered by the phase and neutral line. The maximum rated current (In) the exchange does not exceed 63A. This standard does not include a circuit other than the protected circuit is powered by a battery-powered or AFDD. AFDD expected operated by non-professionals, no maintenance and provides isolation. For the following products, you may require specific requirements. --- With plugs and sockets for household or similar appliance coupler or a combination of general-purpose together AFDD; --- Intended for use in 50Hz or 60Hz outside AFDD frequency. Note 3. For loading plugs, sockets or the AFDD dedicated plug and socket of the AFDD, the technical requirements of this standard can be used with GB 2099.1 (When applicable). When the power supply side may occur when excessive over-voltage, may require special measures (such as a surge protector). The standard technical requirements for normal ambient temperature conditions, these conditions apply to the expectations for pollution degree 2 environment AFDD. For AFDD in the harsh environmental conditions of the region to use, you can add the necessary technical requirements.2 Normative referencesThe following documents for the application of this document is essential.
