Abstract

Disclosed is an electric energy metering device. A processor and a control unit connected with the processor are arranged on a machine cabinet. A voltage transformer is arranged above the control unit on the machine cabinet. A voltage input end of the control unit is connected with a voltage binding post arranged on the machine cabinet. The voltage binding post is connected with a secondary winding of the voltage transformer. The voltage transformer is connected with a voltage wire inlet terminal arranged on the machine cabinet. The processor, the control unit and the voltage transformer are installed in the machine cabinet, the voltage transformer is arranged above the control unit, and high voltage passes through the voltage transformer through the voltage wire inlet terminal, and then is input to the control unit through the voltage binding post. The whole distribution is convenient for wire distribution and wire connection, current wire distribution space is compressed, and meanwhile metering interference is reduced, and accuracy of detected data is improved.

Description

technical field [0001] The invention relates to electric energy metering equipment, in particular to a cabinet type electric energy metering device. Background technique [0002] With the progress and deepening of the reform of the power enterprise system, the assessment of economic benefits is becoming more and more important, and an important part of it is to ensure the accuracy and reliability of electric energy measurement. Power plants and power supply enterprises, power supply enterprises and power consumption enterprises all use electric energy metering devices to carry out electricity settlement. The wiring method of the existing electric energy metering device is complex, which interferes with the measurement of current and voltage signals; moreover, multiple groups of voltage and current lines are likely to cause confusion in the wiring, and the wiring space is large, which brings inconvenience to the maintenance work. Contents of the invention [0003] The obje...
