Is it OK for the ground wire of the street lamp to have a solder point?

The ground welding point of the street lamp refers to the place where the welding is carried out on the ground wire of the street lamp. Under normal circumstances, the ground wire welding point of the street lamp can exist, but some problems need to be paid attention to.

First of all, the location of the ground wire welding point of the street lamp should be selected in a suitable place. Generally speaking, the solder point should be selected at the end of the ground wire to ensure the continuity of the ground wire. At the same time, the welding point should be selected in a position that is not easy to be damaged by external force to ensure the stability of the welding joint.

Secondly, the welding quality of the welding joint should be guaranteed. The welding of the welding joint should comply with the relevant standards and specifications, the welding joint should be firm and reliable, and the resistance of the welding joint should be as small as possible to ensure the conductivity of the ground wire.

In addition, the protection of the weld joints is also important. The weld joint should be treated with anti-corrosion to prevent the weld joint from being corroded and affecting the conductivity of the ground wire. At the same time, the weld joint should be waterproof to prevent moisture from entering the weld point and causing a short circuit or open circuit in the ground wire.

Finally, the inspection of the weld joint is also necessary. Weld joints are regularly inspected to ensure the quality and stability of weld joints. If a problem is found in the welding joint, it should be repaired or replaced in time.

In short, the ground welding point of the street lamp can exist, but it is necessary to pay attention to the selection of the appropriate position to ensure the welding quality, protection and detection. Only in this way can we ensure the normal operation and safe use of the ground wire of the street lamp.

Hello, the ground wire of the street lamp is allowed to have solder points.

Dear, hello, I am glad to answer for you: Do you need to install a grounding wire for Tukai street lights? A:

Dear, hello, the street lamp needs to be sent to install the grounding line lamp If the TN-S system is adopted, the street lamp shell should be grounded repeatedly; If the street lamp adopts the TT system, the street lamp shell should be grounded with a grounding wire for protection grounding, working grounding and lightning protection grounding. Precautions for grounding wire operation: 1. When driving the grounding pile, it is necessary to quickly dredge the large current of the accident by borrowing the ground body to ensure the quality of grounding.

2. Take care of the grounding wire. The grounding wire shall not be twisted during use, and the soft copper wire should be coiled well when not in use, and the grounding wire shall not be dropped from the air or dropped anywhere after the removal of the grounding wire, and shall be passed with a rope, and the cleaning of the grounding wire shall be noted. 3. New staff must be trained and studied in the use of grounding wires, and only after passing the assessment can they be engaged in the operation or use of grounding wires alone.

4. Before hanging the grounding wire, the electricity must be checked first, and the grounding wire is a common habitual violation at the grassroots level, and the grounding wire can not be in contact with the body when hanging. 5. There are many examples of hanging grounding wires at both ends of two sections of the work site to avoid the possibility of users reversing power transmission and inducing electricity. 6. Select the grounding wire of the corresponding specification according to different voltage levels.

7. It is strictly forbidden to use other metal wires instead of dust and ground wires. Thank you for your patience. The above is my full reply, if you are satisfied with my service, please give a thumbs up, and I wish you all the best!

Peace and joy! <>

Lighting fixtures need to be installed with ground wires.

When the lamp is grounded, if the lamp or lamp holder has leakage, the leakage current will lead to the leakage current to the grounding bar in the distribution box through the ground wire;

Then it is led from the grounding to the earth, because the grounding resistance is much smaller than the resistance of the human body, so as to avoid the electric shock hazard that may be caused by the leakage current flowing through the human body.

Yes. Lighting fixtures need to be installed with ground wires.

When the lamp is grounded to the laughing line, if the lamp or lamp holder has leakage, the leakage current will lead to the leakage current to the grounding bar in the distribution box through the ground wire;

Then it is led from the grounding to the earth, because the grounding resistance is much smaller than the resistance of the human body, so as to avoid the electric shock hazard that may be caused by the leakage current flowing through the human body.

Inside the power plant, there is a large metal plate (very large, very large) buried underground, which is the legendary ground. The street lamp is convenient to connect to the map, and it is buried directly under the ground, which is normal because it can form a loop.

The heating will not be electrified, and the electricity will go along the earth nearby, and it will not pass through the heating, which can be assured.

Bury a steel bar in the ground barely make do, but the area of the steel bar is very small, the conductive effect is not good, find a large area of things, iron sheet or something, someone used to steal electricity like this, but also play a certain role, because the electricity is along the underground iron sheet goes, and the meter does not constitute a loop, the meter does not turn, the application is this principle.

Each street lamp is grounded independently, and 50x5 angle steel is used to drive into the ground as an artificial grounding electrode, and the street lamp foundation and lamp pole and other things that need to be grounded are connected with hot-dip galvanized round steel with a diameter of 16 and grounding angle steel. The street lamps are all made of hot-dip galvanized round steel with a diameter of 16, buried to a depth of 1 meter, and the respective grounding angle steel is connected.

The local TT system without PE wire is adopted, and a 300mA leakage protector is added to the outgoing circuit breaker circuit.

All light poles, lamps and lanterns must be firmly connected with the light pole foundation reinforcement, as a grounding device, grounding resistance < 30, after the construction of the light pole foundation, must be tested whether the grounding resistance meets the requirements, if not up to the requirements, the grounding level must be increased, the specific practice sees: "National Architectural Design Standards Atlas" grounding device installation 03D501-4.

Buried ground steel or flat copper, ground resistance less than or equal to 4 ohms.

The grounding wire is buried in the ground and should be thick.

Summary. Is the grounding wire of the street lamp connected to the lamp head? Or is it attached to a light pole?

Kiss Every street lamp must be grounded, otherwise it is easy to have an accident with the <>

The use of TNS system for grounding is to lay the grounding wire PE with the live wire, N line together to make a grounding electrode for every three street lights, is to repeatedly grounding the PE line, there is also a local TT system, that is, the PE line is not laid with the power line, and the street lamp is separately grounded with the grounding electrode. In this case, it is more suitable to use FRP street light poles, FRP light poles are non-magnetic, there is no induction electricity, FRP light poles are also good insulators, pro-<>

If the lamp or lamp holder once there is leakage, the leakage current will lead to the grounding current in the distribution box through the ground wire, and then lead from the grounding to the ground after the grounding row is drawn to the ground, because the grounding resistance is much smaller than the resistance of the human body of the land stove, so as to avoid the leakage current flowing through the <>

The requirements for the design of highway street lamps are as follows: 1. The grounding electrode is made of SC50 L = 2500mm, and the grounding wire is welded with 40x4 galvanized shirt flat steel directly with the foundation bolts, 2. The grounding resistance value is less than 4 ohms, and the grounding line and the lamp pole should be reliably connected, welded, crimped, and can be 3, you can refer to the electrical design and construction of civil buildings, oh <>

The ground wire grounding is electrical grounding, and the foundation grounding is metal grounding, which means that if the metal shell of your street lamp is grounded, the circuit breaker will act when the phase wire leaks or shorts to the ground, and if you only do the foundation grounding, it may be because of the foundation grounding. Street lamp groundingStreet lamp grounding lightning protection, street lamp grounding, not grounding are lightning grounding can only help to introduce lightning into the earth In fact, more is to prevent electrocution or leakage, and the design of the grounding discharge device oh dear [love you reed core you].
