An intelligent power meter with wiring protection function

Abstract

The invention relates to an intelligent electric power meter with a wiring protection function, which comprises a shell, a display interface, a control key, a state indicator and a wiring terminal, and is characterized in that a sealing cover is arranged above the wiring terminal, a fastening mechanism is connected in a transmission manner between the sealing cover and the shell, the fastening mechanism comprises a fastening assembly and a driving shaft, the fastening assembly comprises an operating rod, a hinge pin, a driving gear, a transmission gear and a limiting assembly, an operating power supply module comprises an operating power supply circuit, and the model of an integrated circuit is MAX641. In the intelligent electric power meter with the wiring protection function, the driving shaft is driven through the fastening assembly, sealing of the sealing cover for connection of the wiring terminal and a connecting wire is realized, and thus the reliability of the electric power meter is improved. Furthermore, in the operating power supply circuit, the integrated circuit is high in driving voltage and low in conduction resistance, thereby having an excellent effect for improving the operating state of a field effect transistor, thus improving the operating reliability of the operating power supply circuit, and improving the reliability of the electric power meter.

Description

technical field [0001] The invention relates to the field of electric meters, in particular to an intelligent electric meter with wiring protection function. Background technique [0002] Power meters are power measurement and control equipment that provide solutions for power parameter measurement, power quality monitoring and analysis, and electrical equipment control.

Problems solved by technology

[0004] In the existing power meter, after the power meter is wired, the connecting wire and the connecting terminal are placed in the air, which will cause the connection between the connecting wire and the connecting terminal to oxidize due to the long-term alternation of cold and heat. , so that it is easy to increase potential safety hazards and reduce the reliability of the power meter; not only that, in the working power circuit inside the power meter, there are often too many components working in the power meter, which makes the load of the working power circuit heavier , so that the power supply voltage drops, and at this time the driving voltage of the working power supply circuit is not enough, which makes it unable to work normally and reduces the reliability of the power meter
