Abstract
The embodiments of the invention disclose an electric energy meter housing preventing electromagnetic interference electricity stealing and a preparation method thereof. The electric energy meter housing preventing electromagnetic interference electricity stealing comprises a housing body and a transparent window arranged on the housing body, wherein the housing body is a carbon fiber housing, a nickel layer is plated on the surface of the carbon fiber housing, and the outer surface of the transparent window is covered by a indium tin oxide film. The preparation method is a mechanical nickel plating method for plating the nickel layer on the surface of the carbon fiber housing. According to the embodiments, the electric energy meter housing is provided with an electromagnetic radiation interference prevention function, the interference on electric energy meter metering and the damages to the electric energy meter due to high-technology electricity behaviors are effectively reduced, and the application prospect is wide; in addition, by adopting the electric energy meter housing preparation method, a conventional nickel plating technology is improved, a plated nickel layer which is more compact and uniform is obtained, and the radiation interference resistance of the electric energy meter housing is effectively improved.
Description
technical field [0001] The invention relates to the technical field of electric energy meter shells, in particular to an electric energy meter shell for preventing electromagnetic interference and stealing electricity and a preparation method thereof. Background technique [0002] In the power system, secondary equipment such as some metering devices are highly sensitive to electromagnetic interference. Even some electromagnetic radiation with small energy may cause great interference to these equipment, which will not only cause equipment damage, but also affect the normal operation of the entire power system. Many instability problems in precision measurement circuits can be attributed to high-frequency electromagnetic interference, which is more common for instrumentation amplifiers with differential amplification, because the two inputs of instrumentation amplifiers have high input impedance to ground and are therefore susceptible to Radio Frequency Interference. In in...
