Description

Technical Field

[0001] The present invention relates to the field of smart electric meters, and in particular to a smart electric meter. Background Art

[0002] Smart meters are one of the basic devices for smart grid data collection. They are responsible for collecting, measuring and transmitting raw electric energy data, and are the basis for realizing information integration, analysis optimization and information display. In addition to the basic electricity consumption metering function of traditional electric energy meters, they also have two-way multi-rate metering function, user-side control function, two-way data communication function in multiple data transmission modes, anti-electricity theft function and other intelligent functions.

[0003] In order to facilitate the power company to read data, smart meters are often installed outdoors to reduce the possibility of electromagnetic interference and ensure the normal operation of the meter.

In addition, the power input ends of the two pressurizing mechanisms are simultaneously sleeved on the rotating shaft two, so that wind energy can be converted into electrical energy and mechanical energy. Mechanical energy, electrical energy is stored in the battery, and the mechanical energy is used to drive the pressurizing device to pressurize the outside air into the inside of the meter box for heat exchange; since a refrigeration mechanism is set up, the refrigeration mechanism consumes the stored electrical energy in a windless state, thereby minimizing the input of external electrical energy when adjusting the internal temperature.
