Vintage electricity meters? Smart meters? Which runs fast?

What the hell is wrong with the smart meter, the feeling of the monthly meter flying. Smart meter said: This pot I do not carry!

Today let us completely reveal the truth about the "fast running" of electricity meters!

This kind of flying general feeling is actually normal, because the energy meter is a metering instrument, with high accuracy and high sensitivity. We all know that ten years ago, the electric energy meter was mechanical, and the running time would slow down due to wear and tear, resulting in the illusion of less electricity consumption. Now it has been popularized into a smart energy meter, smart energy meter without aluminum disk, gear and other hardware, reducing the influencing factors, improving the accuracy, due to the reduction of the calibration current, improve the sensitivity of the energy meter. The sensitivity and accuracy of the smart energy meter is much higher than that of the mechanical energy meter, and the current such as the charger that is not pulled can be detected, but the mechanical meter cannot, which is the reason for the increase in electricity consumption.

Some friends have questions again, there is no one living at home, why is the meter still turning?

First of all, is your home pulling the general gate? Have you unplugged the plug?

The meter suddenly runs fast, it may be a leakage of electricity, or it may be that someone is "stealing" your electricity!

Leakage: leakage ≠ electric shock, aging of the line, no pipe laying wires, unqualified household appliances, humid weather, etc. may cause leakage.

Electricity theft: There are still many electricity thieves in the family! Water heaters, refrigerators, set-top boxes, routers, televisions, computers, air conditioners, rice cookers, water dispensers in standby standby... The power cord is plugged in, and the electricity will still sneak away.

So how do we reduce electricity consumption?

The best way is to change the habit of using electricity and save electricity. For example, the charger should be unplugged when not in use, and the power supply should be cut off when the appliance is not in use.

Experiments have proved that a charger that has not been unplugged will consume 0.07 kWh of electricity within 24 hours, and each kWh of electricity will be charged at 5 corners, so it will cost 12.77 yuan more for 1 year. Although this number may not seem like much, it adds up to more. And the charger is always energized, which will reduce the service life and even have the risk of explosion.

There have been news reports that if the central air conditioner is 3000 watts of power when it is used, the power in the standby state is 60 watts, the power consumption of the air conditioner for a day is 1.44 kWh, the monthly consumption is 43.2 kWh, the electricity bill is more than 20 yuan, and it consumes more than 500 kWh of electricity in a year, almost 300 yuan.

When it comes to the power consumption of air conditioners, it involves the power consumption of electric auxiliary heat of air conditioners.

Of course, the air conditioner opens the electric auxiliary heat, the power consumption is very large, this is because in addition to the electricity cost generated by the operation of the air conditioner itself, there is also the additional electricity cost generated after the electric auxiliary heat function is opened, the electric auxiliary heat is actually a heating device added at the outlet position, after opening the electric auxiliary heat, the air conditioner itself and the heating device will generate electricity charges.

Take, for example, a 1.5-horse air conditioner. 1.5 horse air conditioning heating power is usually 1390 watts, if the 1.5 horse air conditioning heating open for an hour the power consumption is about 1.3 degrees, at this time plus the electric auxiliary heat of 1050W, then, 1.5 horse air conditioning at the same time after turning on the electric auxiliary heat, the power consumption of running for one hour can reach about 2.4 degrees, directly doubling the power consumption, which can see how high the electricity bill generated by the electric auxiliary heat opening.

Smart meters can not only accurately measure electricity consumption, but also have more benefits, such as scanning code payment, remote automatic meter reading, etc., which is really convenient and fast!
