摘要

摘要: 大功率无线电波会点燃爆炸性气体。因此，需合理设置无线电发射器发射的无线电波防爆安全功率和能量阈值，限制无线电发射器发射的无线电波功率和能量。欧洲标准CLC/TR 50427:2004《Assessment of inadvertent ignition of flammable atmospheres by radio-frequency radiation-Guide》规定的无线电波防爆安全功率和能量阈值是点火功率和能量阈值。国家标准GB/T 3836.1—2021《爆炸性环境第1部分:设备通用要求》和国际标准IEC 60079-0:2017《Explosive atmospheres-Part 0:Equipment-General requirements》直接引用欧洲标准CLC/TR 50427:2004规定的无线电波防爆安全功率和能量阈值，但错误地将连续无线电波防爆安全点火功率阈值修改为发射器的有效输出功率与天线增益的乘积，从而造成连续无线电波防爆安全发射功率阈值降低；在传输衰减和接收灵敏度一定的条件下，降低了无线传输距离，不利于矿井无线通信系统和人员定位系统的推广应用。因此，国家标准GB/T 3836.1—2021和国际标准IEC 60079-0:2017规定的连续无线电波防爆安全功率阈值应为点火功率阈值，而不是发射器的有效输出功率与天线增益的乘积。

Abstract: The powerful radio waves can ignite explosive gases. Therefore, it is necessary to reasonably set the radio wave explosion-proof safety power and energy threshold emitted by the radio transmitter to limit the radio wave power and energy emitted by the radio transmitter. The radio wave explosion-proof safety power and energy thresholds specified in European Standard CLC/TR 50427:2004 Assessment of inadvertent ignition of flammable atmospheres by radio-frequency radiation-Guide are the ignition power and energy threshold. The national standard GB/T 3836.1-2021 Explosive atmospheres-Part 1: Equipment-General requirements and the international standard IEC 60079-0:2017 Explosive atmospheres-Part 0: Equipment-General requirements directly cite the radio wave explosion-proof safe power and energy threshold specified in the European standard CLC/TR 50427:2004. But the continuous radio wave explosion-proof safe ignition power threshold is incorrectly modified as the product of the effective output power of the transmitter and the antenna gain. This leads to the reduction of the continuous radio wave explosion-proof safe transmission power threshold. Under certain transmission attenuation and reception sensitivity conditions, the wireless transmission distance is reduced. This is not conducive to the promotion and application of mine wireless communication system and personnel positioning system. Therefore, the safe power threshold for continuous radio wave explosion-proof specified in national standard GB/T 3836.1-2021 and international standard IEC 60079-0:2017 should be the ignition power threshold, not the product of the effective output power of the transmitter and the antenna gain.
