Excuse me, how to understand the degree in the smart meter?

In household circuits, watt-hour meter is an instrument used to measure the power consumption of circuits, and it can also be said that it is an instrument used to measure the power consumption of electrical equipment. After the old electric meters were gradually replaced by smart meters, people's electricity consumption also changed subtly. Recently, it was reported that after reading watches for decades, they stopped reading them when they were replaced with new ones. How do smart meters look at degrees? More careful people find that their smart meters are every two seconds, and Chinese characters show the words sharp, peak, flat, valley, active and reactive. The numbers and Chinese characters in the meter will change once, making them mistakenly think that there is something wrong with the meter. So what do these Chinese characters mean? Next, please read our article carefully, and hope that the methods we say can help you.

First of all, "sharp", "peak", "flat" and "valley" represent different time periods, and the electricity fee for each time period is different. The time period marked "Jian" refers to 10 to1:30, 19 to 2 1: 00, and the electricity price is 1.28269 yuan; The period marked "peak" refers to 8: 30 to 10: 30, 18 to19,21to 23: 00, and the electricity price is 1.2 1082. The time period marked "Ping" is 7:00-8:30,11:30-18: 00, and the electricity price is 0.7796 yuan; The "valley" period is from 23: 00 to 7: 00, and the electricity price is 0.34838 yuan. The purpose of this design is to remind people that electricity can be used in disorder, avoid electricity use during peak hours, and achieve the method of safe electricity use in the whole city.

How to read the degree of a smart meter is actually very simple to learn. There are two buttons on the right side of the instrument. Every time you press the button, different words and numbers will be displayed. As long as the owner sees "positive, dynamic and total" on the meter, he can stop pressing it. This figure is the total electricity used by the owner. You can also know your electricity consumption in different periods according to the words "sharp", "peak", "flat" and "valley" displayed. So as to know the electricity consumption of your home, master your electricity consumption time more intelligently, and play a planned electricity consumption method.

At present, domestic smart watt-hour meters can be roughly divided into two categories: mechatronics and full electronic. Electromechanical integration, that is, in the original mechanical watt-hour meter

Add some parts to it, so that it can not only complete the required functions, but also reduce the cost and facilitate installation. Generally speaking, its design scheme is carried out without destroying the original instrument.

It has a physical structure, and adds a sensing device on the basis of not changing its national measurement standard, becoming a smart meter with mechanical measurement and electric pulse output, all of which are electronic.

The formula uses electronic devices with integrated circuits as the core from measurement to data processing, thus eliminating the mechanical parts used for a long time on the electric meter and integrating electricity with mechatronics.

Compared with ammeter, ammeter is smaller, more reliable, more accurate, consumes less electricity, and the production process has been greatly improved, so it is not necessary to be specialized in the original sense.

The advantages of industrial production of industrial electric energy meters will eventually replace electric meters with mechanical parts.

How to see how much electricity is used in a single-phase fee-controlled intelligent watt-hour meter?

Your total electricity consumption is 14.53 kwh, of which 6. 12 kwh is used in peak hours. The Pinggu period used 8.36 degrees, which may be rounded off after the decimal point.

The peak period is when the electricity consumption is high, with many users and large electricity consumption. The power grid will be short of electricity and the system frequency will drop. This period will appear around 8 am to 5 pm.

Flat is electricity consumption. Under the condition of normal and reasonable use, the power grid has sufficient power supply and stable frequency. This period usually occurs from 5 pm to 9 pm.

The valley is a low valley at night, at this time, there will be excess power and rising frequency in the power grid, which will also cause imbalance and lead to the economic loss of the power supply system. Rationality generally appears from 9 pm to 7 am.

Therefore, the state will encourage off-peak electricity consumption, and its electricity price is also determined according to the time period, with the peak time being 0.5 higher than the average and the valley time being 0.5 lower than the average. The peak-valley electricity price is beneficial to enterprises that use a lot of electricity and always produce at night.

From late Pinggu time 10 to 6 am the next day, the electricity price is 0.4883 yuan.

6: 00 a.m.-65438+00 p.m. Valley Time Electricity price: 0.3 yuan.
