Electric energy meter having intelligent alarm function

Abstract

The invention relates to an electric energy meter with an intelligent alarm function, which comprises a casing, a driving assembly arranged above the casing, a water outlet pipe arranged on the back of the casing, an air inlet and a protective casing arranged on the front of the casing. The front of the body is provided with a display, a main control panel and a number of connection columns in sequence from top to bottom, and a condensation unit and a hygrometer are provided in the protective case. The electric energy meter with intelligent alarm function makes the high-pressure The liquid refrigerant evaporates into a low-pressure gas and absorbs heat, thereby achieving the purpose of cooling, ensuring the measurement accuracy and service life, using the fan to accelerate the flow of hot air, speeding up the evaporation of water mist, so that the display can be cleaned and displayed, and the meter reading operation is convenient. Not only that, the pressure condition on the top is monitored by the pressure sensor, and the propeller is driven by the drive motor to drive the birds away, so that the top of the electric energy meter is kept clean.

Description

technical field [0001] The invention relates to an electric energy meter with an intelligent alarm function. Background technique [0002] 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 played a good role. 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 environm...

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
