摘　　要：建立了工况可调电磁屏蔽室,实现了供电供水及大范围温湿度可调。采用干净变频电源,单相供电电压0～300V、频率10～80Hz、容量6kVA,三相供电电压0～500V、频率40～80Hz、容量20kVA。恒温恒湿系统的温度在10℃～35℃连续可调、湿度控制在30%～60%之间,满足了电磁兼容标准对试验环境气候条件要求的最大范围;加装了内循环给排水系统,可给被测设备提供恒温水;设计了电缆连接屏蔽漏斗,隔离屏蔽室内外测试仪器和被测设备。A climatic conditioning shielding room is installed to provide adjustable temperature and humidity. A clean single-phase alternating source provides 0 - 300 V, 10 - 80 Hz, 6 kVA; a clean three-phase alternating source provides 0- 500 V, 40- 80 Hz, 20 kVA, The climate conditioning system provides adjustable temperature between 10 ℃ - 35 ℃ and humidity between 30% 60%, it meets those requirement for testing climate in relative standards, The water supply provides close-cycle heated water. A shielding tundish is designed to connect the cables and isolate instruments outside and EUT inside.
