Summary:The invention provides an anti-harmonic device. The device comprises: an electric energy meter configured to measure electric energy; a low-pass filter connected with the electric energy meter, and configured to filter out harmonic waves; and a shell, wherein the electric energy meter and the low-pass filter are installed in the shell, and the shell is structured to be moisture-proof and dust-proof. The low-pass filter is located between a power supply line and the electric energy meter. The problem that the metering accuracy of the electric energy meter is influenced by harmonic waves can be solved or improved. 本发明提供了一种防谐波装置,包括:电能表,所述电能表构造为测量电能;低通滤波器,所述低通滤波器与所述电能表连接,所述低通滤波器的构造为滤除谐波;壳体,所述电能表和所述低通滤波器安装在所述壳体内,所述壳体的构造为防潮防尘;其中,所述低通滤波器位于供电线路和所述电能表之间。本发明可以解决或改善谐波会影响电能表的计量准确性的问题。
