The three -phase electric meter is used to determine the three -phase four -line communication with the rated frequency of 50Hz and the reference voltage with a reference voltage of 3 × 220/380V.The base rack is made of high -quality aluminum alloy die -casting, and is treated with timely efficiency. It has good stability. The double gem rotor bearing is used to reduce the friction torque.Flexible, adopt high -corrected stubborn alloy permanent magnetic steel, more stable performance.
Three -phase electric meter installation
There is a certain order in the installation of the three -phase power meter. For portable, there are basically no installation steps. You only need to connect the related wires to use it normally.If the three -phase power meter installation is installed in a fixed way, it is necessary to use tools for processing.Generally, you need to consider the local environment, put it in a higher position, and then look at it to fix the screw.
Three -phase electric meter specification
Three -phase electric meter connection method
First look at the few legends in the figure.We are marked with Arabic numerals, namely one to eleven.We use three different letters, u, v, w to represent three different letters, and the zero line is represented by n.Then we come together and connect one by one.First, pick up the first fire U.Then the interface one, then the interface two.The interface is three vacant, and the wires are extended for later use.Then pick up the second fire V, the interface four, and then the interface five.The interface is six vacant, and the wires are stretched out.The connection method of the W fire line and the seven eight -nine interface is the same as above.The fire line connects three input interfaces, which is one of the one -four -seven and three excuses. It is used to connect the current into three current coils. Only when the current passes, the current coil can play a role to calculate each parameter.
Three -phase electric meter price
There is no direct line 400A three -phase electrical meter. Generally, a 5A three -phase electric meter is used with a 400/5 current transformer.The full price is about 200 yuan.
How to look at the three -phase electric meter
1. Read the table directly, read the numbers directly, and then subtract the number of the end of the last month, which is the degree of degree; 2. Some electric meters are equipped with a current transformer, you need to subtract the read number from the last month.After the bottom number, you can multiply the interdependence ratio; this interdependence ratio is marked clearly on the transformer.For example, 50: 5 (10 times), 100: 5 (20 times), 200: 5 (40 times), etc.
