| 一次消谐器运用环境： The operating environment of primary harmonic eliminator: 1.外装在压变的就近边上环境温度-40℃～+60℃。 1. The ambient temperature in the vicinity of the external pressure change is - 40 ~60. 2.电力体系频率为50Hz或60Hz。 2. The frequency of power system is 50 Hz or 60 Hz. 3.烈度8度以下区域首要电气功能首先查看外观是否无缺。首要电气功能首先查看外观是否无缺。 3. The primary electrical function of the area below 8 degrees of intensity is to check the appearance first. The primary electrical function is to check the appearance first. 4.在投运前,丈量直流参考电压U1mA值，不得小于GB11032-2000规定值，丈量0.75 U1mＡ下的走漏电流，其值不大于50μA，投运后每四年测一次，看是否符合要求， 无空隙避雷器不允许做工频放电电压试验。 4. Before commissioning, the DC reference voltage U1mA should not be less than GB11032-2000, and the leakage current under 0.75 U1mA should not be less than 50 UA. After commissioning, it should be measured every four years to see if it meets the requirements and no gap arrester is allowed to do power frequency discharge voltage test. |
