How can a mechanical meter collect pulse signals?

Summary. How to connect the pulse output of the meter, if it is a three-phase meter, it can be connected to the three-phase power supply. If it is a 3-phase four-wire watt-hour meter, the 1 4 7 on the meter terminal is connected to the current in and 3 6 9 is connected to the current out, and they are shorted to the ground.

2 5 8 connected to a b c three-phase voltage, 10 connected to neutral line. The connector is hung with tin, the tape is wrapped firmly, high voltage, waterproof, insulation, and it is okay to wrap it in turn, you can do three decorative grids together with the meter box, 2 can be used as furnishings, and the surface of the meter box is decorated, that is, the pulse output is usually represented by P+ and P, respectively, and the pulse terminal of the electric energy meter is connected to + and . 2. The RS485 output is usually used to connect with the A terminal and B terminal on the energy meter.

How to connect the pulse transmission of the meter, if it is a slow three-phase meter, you can connect the three-phase power supply. If it is a 3-phase four-wire watt-hour meter, the 1 4 7 on the meter terminal is connected to the current in and 3 6 9 is connected to the current out, and they are shorted to the ground. 2 5 8 connected to a b c three-phase voltage, 10 connected to neutral line.

The joint is hung with tin, the tape is wrapped firmly, high voltage, waterproof, insulation, and it is okay to be buried in turn, and you can do three decorative grids together with the meter box, 2 can be used for furnishings, and the surface of the meter box is decorated, that is, the pulse output is usually represented by P + and P, respectively, and the pulse terminal of the energy meter is connected to + and . 2. The RS485 output is usually used to connect with the A terminal and B terminal on the energy meter.

Firstly, phase A on the power supply side is connected to the inlet end of phase A of the electricity meter, and at the same time, an old matching wire is connected from phase A to phase A on the load side. Then connect the B-phase wire on the power supply side to the B-phase inlet end of the meter, and connect the wire from the B-phase outlet-end to the B-phase end of the load side; Then connect the C-phase wire on the power supply side to the power attendant to refer to the slippery end of the C-phase inlet line of the meter, and then connect the wire from the C-phase outlet end to the C-phase on the load side; Finally, a wire can be connected from the neutral port of the meter and connected to the neutral end of the load side.

The pulse output wiring adopts a special end button junction box. The installation and use of the watt-hour meter has been inspected and qualified before leaving the factory, and sealed with a lead seal, which can be installed and used. If the watt-hour meter is not sealed or stored for too long, it should be re-calibrated by the relevant departments before installation and use to ensure the accuracy of measurement.

The watt-hour meter should be installed indoors, choose a dry and ventilated place, and the bottom plate of the watt-hour meter should be placed on a solid and durable, non-vibrating wall, and the installation height is recommended to be about meters, and the watt-hour meter should be vertical and not inclined after installation. The watt-hour meter is connected to the line according to the specified phase sequence (normal phase sequence), and is wired according to the wiring diagram on the end button box cover.

It is best to introduce it with a copper connector to avoid the copper connector in the end button box from burning the watt-hour meter due to poor contact. The watt-hour meter is used in places with more thunderstorms, and lightning protection measures should be adopted at the installation site.

Title. In low-voltage distribution circuits. Many protective devices have electrical pulse outputs and input terminals

I would like to know what your input or output pulses do. Where and what it is used for. `?

If you want to input a pulse. What is the projection circuit pulse signal through.

The output is to send a signal to the control mechanism, and the input is to receive the control signal sent by the control mechanism to the protection device. If you want to input a pulse. What is the projection circuit pulse signal through. Through the control cable!

Generally, the output is sent to other device interfaces through optocouplers.

For example, PC357, 2701 and other optocouplers are OK.

Summary. Firstly, phase A on the power supply side is connected to the inlet end of phase A of the meter, and at the same time, a wire is connected from phase A to phase A on the load side. Then connect the B-phase wire on the power supply side to the B-phase inlet end of the meter, and connect the wire from the B-phase outlet-end to the B-phase end of the load side; Then connect the C-phase wire on the power supply side to the C-phase inlet end of the meter, and then connect the wire from the C-phase outlet-end to the C-phase on the load side; Finally, a wire can be connected from the neutral port of the meter and connected to the neutral end of the load side.

I hope it helps you and I wish you happiness and happiness every day!

How to connect the pulse output of the meter.

Hello, glad to answer for you. Firstly, phase A on the power supply side is connected to the inlet end of phase A of the meter, and at the same time, a wire is connected from phase A to phase A on the load side. After the object, the B-phase wire on the power supply side is connected to the B-phase inlet end of the meter, and the wire is connected from the B-phase outlet-end to the B-phase end of the load side; Then connect the C-phase wire on the power supply side to the C-phase inlet end of the meter, and then connect the wire from the C-phase outlet-end to the C-phase of the load side. Finally, a wire can be connected from the neutral port of the meter and connected to the neutral end of the load side. I hope it will be helpful to you, and I wish you happiness every day!

There are two pulse lines above plus or minus these two years to be connected, if you connect, you can connect it, and you can not connect it.

It's okay not to pick it up.

If these two small wires are connected, he is connected to **.

There is an instruction on the terminal cover, just take a look at it.
