Intelligent electric energy meter with anti-corrosion performance

Abstract

The invention discloses an intelligent electric energy meter with anti-corrosion performance. The intelligent electric energy meter comprises a PCB, a driving circuit is arranged on the PCB, a first interface is fixedly connected to the side edge of the PCB, the first interface is connected with the driving circuit, the driving circuit inputs driving current and driving voltage to an installation circuit, the side edge of the first interface is fixedly connected with two second interfaces, the second interfaces are connected with the driving circuit, and the PCB is provided with nanometer waterproof paint. The proper nano waterproof paint is smeared on a component of the intelligent electric energy meter, so that a nano-scale coating film with a very good hydrophobic effect is formed on the surface of the PCB, a lotus leaf effect is formed; and a strong and powerful protective film can be formed on the surface of the electronic component through the ultrathin coating film, so that the component on the PCB of the electronic product are effectively prevented from meeting water, being affected with damp and being corroded by acid, alkali and salt.

Description

technical field [0001] The invention belongs to the technical field of electric energy meters, in particular to an intelligent electric energy meter with anti-corrosion performance. Background technique [0002] Energy meters are instruments used to measure electric energy, also known as watt-hour meters, fire meters, and kilowatt-hour meters. AC watt-hour meters can be divided into single-phase watt-hour meters, three-phase three-wire watt-hour meters and three-phase four-wire watt-hour meters according to their phase wires. Energy meters can be divided into electromechanical energy meters and electronic energy meters (also known as static energy meters, solid-state energy meters) according to their working principles. Electromechanical energy meters are used in AC circuits as ordinary energy measuring instruments, and the most commonly used ones are inductive energy meters. Electronic energy meters can be divided into fully electronic energy meters and electromechanical ...

Problems solved by technology

[0003] However, at present, electrical equipment is severely corroded by salt spray; because electrical equipment is exposed all the year round, exposed to wind, sun, and salt spray corrosion, the shell of electrical equipment is more likely to corrode under severe weather conditions; the joints are corroded significantly, easy to oxidize and expand, Poor contact caused by shrinkage; copper-copper joints corrode relatively lightly, and aluminum-aluminum joints corrode more severely. It is obvious at the copper-aluminum joints that the aluminum joints are white and have burn marks; especially for tidal power generation. Electric energy meters, because they are close to the sea, are particularly severely eroded by salt spray; therefore, it is urgent to provide a smart electric energy meter with anti-corrosion performance to solve the problem of anti-corrosion of electric energy meters
