140DAI45300  磁芯電流探頭可以測試直流電和交流電，并且測試直流電和高頻交流電信號的方法不同?；魻?/span>傳感器用于測量直流和低頻交流電，而電流互感器用于測量高頻交流電。交流電在電流互感器的鐵芯中產(chǎn)生磁場，然后電流在第二個繞組電路中汲取并饋入示波器。如下所示：

交直流混合探頭的結(jié)構(gòu)圖如下：

在降額曲線中，只能在低于10K的頻率下測試15Arms的最大連續(xù)電流。

磁芯電流探頭降額功率的主要原因是，當(dāng)測量高頻和高振幅電流時，探針本身會發(fā)熱。這些熱量甚至可能導(dǎo)致探頭融化并損壞。自熱的主要原因有兩個：

1、高頻電流產(chǎn)生交變磁場。磁場在導(dǎo)體上感應(yīng)出渦流，頻率越高，渦電流越大，渦流會導(dǎo)致導(dǎo)體發(fā)熱和渦流損耗。

2、在測量高頻電流時，磁芯電流探頭使用變壓器方法進行測量。隨著高頻信號在導(dǎo)體上產(chǎn)生趨膚效應(yīng)，導(dǎo)體的電阻增加，導(dǎo)體產(chǎn)生熱量，頻率越高，皮膚現(xiàn)象越明顯。

為了避免熱損壞核心流量探頭，在使用時應(yīng)考慮待測電流的頻率及其諧波分量及其幅度之間的關(guān)系。
