Problems solved by technology

[0002] The watt-hour meter is the most commonly used metering equipment for industrial power supply and domestic electricity consumption. It is necessary to check the reading of the watt-hour meter frequently during maintenance or meter reading, but we often cannot read it at night or when the light is relatively dark. The reading of the watt-hour meter, and the lens of the watt-hour meter is in the external environment for a long time, the lens will become blurred or even damaged over time, and the reading of the watt-hour meter cannot be recognized

Abstract

The invention discloses a novel watt-hour meter which is convenient for reading at night, and relates to the technical field of power system metering equipment. Including the watt-hour meter body, a ring-shaped LED light is provided around the reading of the watt-hour meter on the lens of the watt-hour meter, and a mirror cover hinged with one side of the watt-hour meter is also provided on the surface where the lens is located. The mirror cover is opened and closed by means of a motor at one end of the rotating shaft, and the motor and the LED lamp are controlled by a control unit located at one side of the watt-hour meter. The mirror cover on the watt-hour meter can ensure that the lens surface is clean and not damaged. The mirror cover is automatically opened and closed to make the operation more convenient. The LED light on the lens can illuminate the reading at night, which is convenient for the staff to read.

Description

technical field [0001] The invention relates to the technical field of power system metering equipment. Background technique [0002] The watt-hour meter is the most commonly used metering equipment for industrial power supply and domestic electricity consumption. It is necessary to check the reading of the watt-hour meter frequently during maintenance or meter reading, but we often cannot read it at night or when the light is relatively dark. The reading of the watt-hour meter, and the lens of the watt-hour meter is in the external environment for a long time, the lens will become blurred or even damaged over time, and the reading of the watt-hour meter cannot be recognized. [0003] For above problem now, need a kind of novel watt-hour meter, can guarantee the surface cleanness of eyeglass, can read the reading of watt-hour meter again at night. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a new type of wat...
