Problems solved by technology
Therefore, when the demander has different specifications for the three-phase electric energy meter, it will often cause great trouble to the producer. For example, in order to meet the needs of three-phase electric energy meters of different specifications, the producer needs to be equipped with various specifications in production. Materials and multiple production lines can easily lead to waste of space and confusion in storage, which is not conducive to the company's production management and improvement of production efficiency, and may even cause waste of resources

A three-phase electric energy meter wiring mode adaptive method belongs to the technical field of electric energy meter terminals, and the electric energy meter comprises an MCU control unit and an analog data acquisition unit connected with the MCU control unit by means of a metering processing unit. By means of a power management unit, a switching power supply unit connected with an MCU control unit, and a liquid crystal display unit, a storage unit, a communication unit, a key unit, a load control unit and a reference voltage ground switching control unit which are connected with the MCU control unit, the self-adaptive method comprises the step of judging the wiring mode of the three-phase electric energy meter by adopting a triangle method and a slope method. And the wiring mode of the electric energy meter can realize three-phase three-wire and three-phase four-wire self-adaption.
Description
technical field [0001] The invention belongs to the technical field of electric energy meter terminals, and in particular relates to an adaptive method for the wiring mode of a three-phase electric energy meter. Background technique [0002] At present, there are electric energy meters with various voltage specifications in the market. For example, the domestic three-phase electric energy meter specifications include three-phase four-wire 3*220 / 380V electric energy meter, 3*57.7 / 100V electric energy meter and three-phase three-wire 3*100V electric energy meter. In foreign countries, the three-phase electric energy meter has certain differences in voltage according to different regions. Therefore, when the demander has different specifications for the three-phase electric energy meter, it will often cause great trouble to the producer. For example, in order to meet the needs of three-phase electric energy meters of different specifications, the producer needs to be equipped w...
