I. Employment presentation - overview
Electric meters, also known as electrical meters, fire meters, are instruments for measuring electrical energy and are an important basis for our payments, based on a variety of high-end technologies, such as microprocessing technology, sampling technology, design technology, and a high-technology product that is interdisciplinary and multidisciplinary and is now prevalent in our households。
Ii. Employment studies - classification
There are a variety of types of energy meters, which can be classified according to their use as non-functional, functional, depleted, prepaid, intelligent, etc.; depending on the nature of their access to the power source, they can be divided into direct current and communication meters; depending on their structure, they can be divided into split and integrated meters; depending on the manner in which they are installed, they can be divided into direct and indirect access meters; depending on their access line, they can be divided into single-phase, three-stage and four-phase electrical meters; depending on its working principles, it can be divided into electrons and sensory meters。
Iii. Electronic structure
The working method of the meters is this: first, they are connected to the circuits and generate a transient current in the voltage wires and current wires, which in turn produce a transient magnetic flux in their iron cores; second, the transversal magnetic flux produces vortex in the aluminium disk; and, again, the vortex in the aluminium disk is subject to the effect of the magnetic field, which allows the aluminum disk to rotate; finally, the aluminum wheel drive counters are digitally reflected in the energy they consume。
The greater the power of the load consumption, the greater the currents generated in the voltage wire and current wires, the greater the vortex generated in the aluminium disc, the greater the power of the aluminum discs, the greater their count; and, on the other hand, when the power of the load is consumed, the smaller the currents generated in the voltage wires and current circles, the smaller the vortex generated in the aluminium discs, the smaller the force of the aluminum discs, the smaller the numbers。
Iv. Equipment structure - electronic electronic and sensive electronics
Depending on the method of work, the meters can be divided into electrons and sensory meters, where they first receive voltage and current values, and then the final electrons count by multiplying their vectors. Based on this method, they produce prepaid meters, time-cost meters, multifunctional meters, etc., which further meet our requirements for measuring electricity in different contexts; sensible electrons are based on electromagnetic induction principles, which present currents, voltages, etc. In the form of force rectangulars, drive the aluminum discs towards count functions, have the advantages of visualization, preservation of data in case of power outages, dynamic continuity, etc., and are equally widely applied。
