The invention relates to an electric power measurement displaying device of a double-source-system electric locomotive and a mounting structure. The displaying device comprises an alternating current-direct current voltage and current sampling unit, an alternating current-direct current electric energy meter unit, a control unit, a communication interface unit, a data storage unit, a display driving unit, a LCD (liquid crystal display) unit and a power module. Alternating current voltage and current signals which are from a contact network or direct current voltage and current signals which are from a power storage battery of a bicycle are respectively inputted to corresponding electric energy meter units through corresponding voltage and current sampling units; and after the alternating current voltage and current signals and the direct current voltage and current signals are processed and stored, data comprising alternating current-direct current traction power consumption, regenerative braking feedback electric energy and alternating current-direct current voltage and current are displayed. The electric power measurement displaying device can stably work under two power systems comprising an AC (alternating current) 25kV alternating current contact network and a DC (direct current) 3kV vehicle-mounted power type lithium battery; the reliability and the electromagnetic compatibility are high; and the electric power measurement displaying device can be in communication connected with other devices on a vehicle.
Description
technical field [0001] The present invention relates to an electric energy consumption measuring instrument for main railway lines, electric locomotives for industrial and mining enterprises, and electric vehicles for urban buses, in particular to an AC / DC electric energy metering display device and its Install structure. Background technique [0002] At present, the electric locomotives developed in my country for main railway lines, stations, and industrial and mining enterprises all adopt a single AC catenary power receiving method, and the corresponding locomotive power consumption measuring instruments only measure and display AC power. For example, in China This is described in utility model patent specification CN203224541U. According to the overall requirements of the country to build a resource-saving society, the dual-source "electricity-electricity" hybrid electric locomotive based on catenary power receiving type and battery power storage type has technical advan...
