Abstract

The invention belongs to the technical field of electric equipment, relating to a guide rail-type electric energy meter. In particular, the invention relates to a three-phase four-wire prepaid electric energy meter. The technical scheme is characterized in that the guide rail-type three-phase four-wire prepaid electric energy meter comprises a main body and a guide rail connected on one side of the guide rail; the main body is fixed by the guide rail; the right side of the main body is provided with a screen and multiple wiring holes; the screen is used for display data information; the wiring holes are used for connecting electrical apparatus elements in the main body with external wires; the screen comprises a surface film and a backlight plate; a liquid crystal layer is arranged between the surface film and the backlight plate and adhered and connected to the surface film and the backlight plate; the outside of the backlight surface is attached to a polarizing film; metal thin films are coated on the surface film and the inner wall surface of the backlight plate; and after a circuit board is electrified, the metal thin films in instrument parameter shapes are exposed on the screen so that the pattern is telescopic and has good display effect.

Description

technical field [0001] The invention belongs to the technical field of electric power equipment, and relates to a guide rail-type electric energy meter, in particular to a three-phase four-wire prepaid electric energy meter. Background technique [0002] The DIN-rail three-phase prepaid energy meter is mainly used in the field of electric energy management of the three-phase four-wire network with a frequency in the range of 45~65Hz. It can measure the power information in the power grid, and exchange data with the host computer through encrypted IC card or 485 communication. The built-in high-power relay of the meter can realize local tripping and closing operations, thereby realizing the prepayment function; users can set the internal parameters of the electric energy meter according to the actual situation on site, which is easy to use, simple to operate, and high in accuracy; it is widely used in various residential buildings, intelligent Construction, bazaars and dormi...
