What s in the power well???

1: There is a bridge in the electric well; There are cables and wires on the layer and the upper layer in the tray, and the cables and wires are regularly and neatly fixed in the tray;

2: Some wells have meters, some wells do not have meters to see the design and use requirements to determine, if it is a meter reading to the household, then each household can be put together and numbered, so that the meter reader can view.

There should be a 380-volt high-voltage line in the strong electric well, and whether there is a transformer in it depends on the use requirements, and the distribution room should have a transformer, a switch cabinet and a voltage and current meter.

1. The strong electric well has a distribution box, which is the legendary water heater. And then there's the cable tray, and that's what you can see.

2. Yes, it is the electricity meter used to check the meter.

3. Residential strong electric wells are 220V medium voltage, which is not considered high-voltage electricity. There is no transformer in the strong electric well, and the transformer is in the substation and distribution room.

The projects I came into contact with had cables in the strong electric wells, the distribution boxes that supplied power to the common parts, and the others had not been touched. An electricity meter is something that measures the amount of electricity you use in your home, and it should generally be in the meter box, not in a strong well. Strong electric wells are generally 380V voltage, and some super high-rise buildings will have a substation room in the middle, and there may be 10kV high-voltage cables, which I have heard of.

Strong electric wells refer to the wells where wires and cables are laid for power supply and lighting.

Summary. High-rise electric well: It is the reserved channel for cable and wire laying.

What do high-rise electric wells and water wells mean?

High-rise electric well: It is the reserved channel for cable and wire laying.

Water well: It is the terminal of the branch of the public facility into the building, and the manhole is convenient for maintenance and inspection, and it is an indispensable facility.

Electric wells: There needs to be electrical circuits inside the building, and the electric well is a shaft set up inside the building for the passage of these pipelines, through which these cables are sent to each household and unit. Electric wells are divided into strong collision without electricity and weak electricity.

Strong current is lighting and power, and weak current is mainly low-voltage parts such as communication burning, noise mold monitoring, and data.

Wells: generally 60-80 cm long and 30-40 cm wide. Pants are used to put Hu Jingzhi water supply riser, reclaimed water riser, heating supply and return water riser leaking dates.

Its function: one is to place the water supply riser, the water riser, the heating supply and return water riser; the second is to play the role of valve control; the third is a manhole that is easy to maintain and detect; Fourth, natural gas is used for heating in plumbing.

Do you have any other questions? If you are full of trembling for my service, I hope to give a 5-star praise at your convenience! Have a great day!

Strong electric well refers to the well that is installed in the common part of the building to provide power electricity, lighting electricity, and cable laying for the whole building, and various power distribution devices can also be installed in the well, such as distribution boxes.

Weak current wells belong to electrical shafts, which are electrical shafts for laying weak current lines. An electrical shaft, also known as a cable shaft, is a passage used in high-rise or multi-storey buildings to deploy vertical trunk communication cables, etc. Generally, the weak current box of this floor is also placed in the electrical shaft.

1. The installation voltage of strong electric wells is different from that of weak electric wells.

The strong power well is generally the installation of AC wires such as mains 220 and high-voltage power in the building.

The lines installed in weak current wells mainly include network cables, ** lines, monitoring lines, radio frequency cables, TV, etc., and generally weak current wells are signal lines.

2. The transportation mode of strong electric wells and weak electric wells is different.

The strong current (electricity) well is the power power transmission, and the weak current (telecommunication) well is the audio-visual signal transmission. The separation of strong and weak electric wells is to prevent the magnetic field generated when the strong current passes through to interfere with the audio-visual signal, which is also the reason why the power supply line and the signal line cannot be penetrated into a line pipe together during the construction of the project.

There are mainly bridges, cables, and meters in the well room. The bridge and cable are done by the construction unit, and the equipment and facilities such as the meter are done by the Electric Power Bureau, and the initial installation fee is charged.

Electric wells are divided into strong electricity and weak electricity, strong electricity is lighting and power, and weak electricity is mainly communication, monitoring, and data wheel trapped low-voltage parts. The electric well is a space that runs vertically through the building, for the strong and weak current cables to be laid vertically, and then laid to all parts of the floor after reaching each floor, and the electric well is closed on each floor or compartment.

Generally, the circuit should be planned well in the design, in order to use it more safely, generally speaking, strong electric wells and weak electric wells will be configured, so what is the difference between strong electric wells and weak electric wells?

1. Different functions: strong electric wells generally refer to the wellhead of the pre-embedded pipe for power consumption, usually the wellhead after the low-voltage cabinet is outlet, and the weak electric well generally refers to the wellhead of the embedded pipe of the network and the network.

2. The AC frequency is different: the frequency of strong electricity is generally 50 Hz, that is, the frequency of industrial electricity, while the frequency of weak electricity is often high frequency or ultra-high frequency, in kilohertz and megahertz.

3. Different transmission methods: strong current is transmitted by transmission lines, and weak current transmission is divided into wired and wireless.

The above is the full introduction of what is the difference between a strong electric well and a weak electric well.
