A kind of electric energy meter with automatic and clear display

Abstract

The invention relates to an electric energy meter with automatic and clear display. The electric energy meter comprises a main body, a dispelling mechanism arranged above the main body, a water outlet pipe arranged at the back side of the main body, an air inlet and a protective shell arranged on the front side of the main body, wherein the front side of the main body is provided with a display screen, a control panel and a plurality of wiring posts in sequence from top to bottom, and a condenser and a hygrometer are arranged inside the protective shell. The electric energy meter with automatic and clear display evaporates a high-pressure liquid refrigerant into a low-pressure gas by means of an evaporator in a refrigerating mechanism and absorbs heat so as to achieve the purpose of reducing temperature, ensures the measurement precision and prolongs the service life, converts the high-pressure refrigerant gas into the high-pressure liquid refrigerant by means of the condenser and releases heat, accelerates the flow of hot air by utilizing a fan, accelerates water vapor evaporation so that the display screen can display clearly, facilitates the meter reading operation, monitors the pressure conditions at the top part by means of a pressure sensor, drives blades to rotate by adopting a driving motor so as to dispel birds, and keeps the top end of the electric energy meter clean.

Description

technical field [0001] The invention relates to an electric energy meter with automatic and clear display. Background technique [0002] An electric energy meter is an instrument used to measure electric energy, also known as an electric meter, a fire meter, and a kilowatt-hour meter. The electricity consumption is displayed on the display screen of the electric meter in units of degrees. The staff who check the electric meter will check the numbers in the display screen of the electric meter every month. The difference between the value of the electric energy meter in this month and the previous month is the electricity used per month. [0003] At present, energy meters are generally installed outdoors. As long as the design of the energy meters on the market is to prevent electricity theft, dust, water, and the impact on the environment outside the energy meter, a fully sealed meter structure is adopted to prevent electricity theft. , Dustproof, and water release have pl...

Problems solved by technology

However, the internal circuit board of the electric energy meter is in a closed environment. After long-term operation, the internal temperature gradually rises, and the interior of the electric energy meter lacks corresponding cooling measures. Under high temperature conditions, the electric energy meter not only reduces the measurement accuracy, but also tends to accelerate the internal components. The degree of aging damage, not only that, when the electric energy meter works in an environment with high humidity or rapid changes in temperature and temperature, the protective shell on the electric energy meter is prone to fogging, and the fog inside the protective shell is not cleared, so that the electric energy meter The numbers on the meter cannot be read normally, which affects the normal meter reading work

At the same time, in some rural areas, the electric energy meter is usually set under the eaves in the open air, and the top of the electric energy meter forms an angle with the wall, which provides a good environment for some flying birds or spiders to weave their webs. Because of the disturbance of these animals, the surface of the electric energy meter changes. dirty, further affecting the reading of the staff on the meter
