The abbreviation of the electric energy meter is the instrument used to measure electrical energy, also known as electrical meter, fire watch, electrical meter, kilowatt -hour meter, and point out the meter with various electrical volumes.
Meter power
The power of the meter generally has a fixed size. When it exceeds this value, we call this phenomenon the load. At this time, the computer is the electrical appliance of the load.We know that the box -shaped box, the computer source.This electricity is a load for the network.The principle of the non -linear load (rectifier load) source of the electric switching switching switching (rectifier load) sources AC electricity is high, and then turns high voltage to high voltage and high current, and then changes high -frequency AC.22 switching power supply, these 20 inputs are effective in a capacity load, but its waves are positive but have distorted, and then the sine wave of the rules.
The meter does not go away
The electrophoretic meter may be burned.The reason for burning may be instantiated overvoltage. The instantaneous over -voltage is an instant increase of the circuit voltage. The amplitude value can reach several times that of the rated voltage, but its duration is very short and often uses microseconds.Its voltage peak value is extremely high, the waveforms are steep, but the average power is small.
Meter principle
The basic working principle is that when the meter and the measured circuit are received together, the AC electricity will pass through the current and voltage electrical rings. At this time, the magnetic transformation will appear.It will be felt, and the magnetic field will cause the vortex to be forced, and then the internal work display of the aluminum plate will start.When the power is consumed more, the larger the current ring will respond. At the same time, the vortex will be perceived by it, so that the readings can be induced according to the current size. The design is very clever.This is the simple process of the work of the electric energy meter.
Electric meter price
At present, ordinary home products, the price of general quality meters is about 50-70 yuan.It can be purchased in general markets. Most of these products do not have good after -sales service guarantees.For the price of some brand meters, most of them are about 500 yuan.
Meter model
Portetal connection
General home meter connection method, the wiring of single -phase electric meter: If it is 1234 from left to right, then 1 is the power line that comes in, 2 is the line of fire at home.Go to the home of the zero fire and zero reaction, the electronic watch does not turn, and the pulse surface reverses.The correct method of the single -phase table: 1.3 Inlet 2.4 Enter 1.2 fire 3.4 zero
How to look at the meter
First of all, remember the number of readings last month, and then use the reading of the month -last months reading = the number of use this month.If the number box is red, it is a decimal, which can be made every five, otherwise it is an integer.The reading of the electrical meter is very easy, and there is a multiplier label on the digital frame or below.
