What are the precautions for decoration electricians, basic knowledge of decoration electricians, pr

Pay attention to 6 points in the decoration of new houses: 1. Design the style of the house first; 2. Hard installation should be determined and then installed; 3. The decoration of the living room should consider the placement of furniture and household appliances; 4. The ceiling light in the bedroom is equipped with dual control, and the corridor is equipped with voice control; 5. Kitchen gas alarm, sink away from stove socket; 6. Leave a certain slope on the balcony and bathroom to install floor drains.

The basic knowledge that you need to master to learn electrician from scratch includes: basic knowledge of electrician, electronic technology and application, electrical diagram, high and low voltage electrical components, common tools for electricians, electrical instruments and measurements, transformers, transformers, voltage regulators and electromagnets, generators and motors, high and low voltage power distribution, lighting installation, motor control circuits, PLC control technology, electrical maintenance, safe electricity use and electricity saving, common materials for electricians, etc.

The whole knowledge system has a certain degree of difficulty, people who do not have a little electrician foundation, want to learn electrician theory and practical operation from scratch, it is best to find a regular school to apply for electrician training courses. It's not that you can't learn from zero-based self-study, but if you read books by yourself, the learning efficiency will be relatively low, and electricity itself is a very dangerous thing.

The electrical industry has a lot of room for development, the country's major enterprises, foreign-funded enterprises, power plant substations, power supply bureaus, property, imitation new energy vehicles, charging piles, photovoltaic power generation, high-speed railway, subway management and other employment enterprises are in urgent need of a large number of power-related talents, with the vigorous development of the urbanization market, the future of the electrical industry talent demand gap will be greater, if you are interested in doing electricians, it is recommended to sign up for consultation as soon as possible.

1. Holding a certificate is the premise, and the job responsibilities should be well remembered: special operations personnel have been engaged in this type of work for more than 10 years during the validity period of the special operation certificate, and strictly abide by the relevant safety production laws and regulations, with the consent of the original assessment and certification authority or the assessment and certification authority in the place of practice, the review time of the special operation certificate can be extended to 1 time every 6 years.

2. The implementation of the regulations must be strict, and the protective equipment must be worn: the electrical workers should strictly implement the management system and electrical operation procedures, and wear and use labor protection equipment correctly during the work period to avoid and reduce all kinds of accidental injuries.

3. The equipment inspection should be comprehensive, and the on-duty operation records should be complete: the electrical workers should conduct comprehensive inspections and inspections of the distribution equipment and facilities on a regular basis, and conscientiously do a good job in various operation management records, including equipment inspection records, equipment maintenance records, tool testing records, operation analysis records, duty records, etc.

4. Regular inspection, standardized use and storage of insulating appliances: In accordance with the provisions of the "Safety Management Code for Substation and Distribution Room" (DB11 527-2015), the workplace should be equipped with high and low voltage electrician safety appliances and regularly tested.

5. Warning signs should be used correctly, and the equipment should be cleaned frequently: the warning signs should be equipped with complete warning signs according to the regulations and used correctly, so as to prevent the occurrence of dangerous operations. Regularly maintain, clean and remove dust from the substation and distribution room, distribution cabinet and electrical equipment and facilities, keep the environment of electrical equipment and facilities clean and tidy, and do not store items unrelated to the operation of electrical equipment.

6. The illustration should be clear, and the distribution direction should be correct: the various diagrams of the substation and distribution room should be hung neatly, the illustration should be clear and correct, the warning signs should be eye-catching, and there should be a circuit diagram in the distribution cabinet (box), and there should be a clear road name mark.

7. The current matching is the key to the circuit equipment with the switch: the electrical circuit and the electrical equipment should be configured according to the standard between the switch and the electrical equipment, the switch and the line, and the switch capacity should match the allowable current carrying capacity of the wire and the equipment capacity, so that the switch can really play a role in circuit protection.

8. The circuit laying should be in accordance with the standard, and the grounding of the equipment should be ensured: lay the electrical circuit according to the standard, do a good job in the fixed line, pipe protection, etc., and the equipment should do a good job in the installation and maintenance of the protective line in accordance with the requirements of the specification.

9. Electricity shall not be overloaded, and the temporary electricity shall be strictly supervised: it is strictly forbidden to overload the electricity and privately connect the power cord, and when the temporary electricity is required, it shall be approved by the relevant departments of the enterprise, and strict management measures and safety technical measures shall be taken to prevent the occurrence of personal and fire accidents.

10. The emergency plan is regularly drilled to reduce the risk at critical moments: it is necessary to formulate various accident plans such as fire, electric shock, and power outage in combination with the actual situation of the enterprise, so that electricians and related personnel are proficient, and regularly organize drills to improve emergency response capabilities, and in the event of an accident, it can reduce secondary disasters and reduce accident losses.

1.Horizontal and vertical.

Hydropower decoration pays attention to horizontal and vertical, which is not only beautiful and beautiful, but also ensures the quality of the circuit through the same pipeline fixation with the same spacing, and will not be touched off the pipeline because of the subsequent construction links, and the later leveling and plastering tiles can be in contact with a large area to prevent the later stage from falling off, so the method of hydropower laying must be horizontal and vertical two points and a line, and the wall pipeline goes in a vertical line to avoid transverse slotting, otherwise the load-bearing wall will be damaged.

2.There should be a lock between the conduit and the wire box.

During construction, the wire pipe can not be directly inserted into the wire box, let alone flow out of a section, so that the wire can be inserted into the wire box, which is standard. The insertion of the conduit into the wire box is not conducive to wiring; If the wire pipe is too short and the wire box is not inserted, the cement will fix the wire in the later stage.

3.Keep a distance between strong and weak electricity.

In order to avoid the influence of strong current on the signal of weak current, it is recommended to keep more than 50cm between strong current and weak current when wiring.

4.The angle of the corner of the conduit.

In order to facilitate the later stringing and maintenance, there should be an angular arc at the turning place. At the same time, it should be noted that there cannot be more than 2 turns in a single line.

5.Pay attention to the number of threads threaded in the conduit.

In the national standard, the cross-sectional area of the wire in the line pipe can not exceed 40% of the cross-sectional area in the line pipe, and now many families use 4 points and 6 pipes, such as 6 points of line pipes, and generally the threading can not be more than 5.

6.Reserved wires in the kitchen and bathroom.

The top surface of the kitchen and bathroom should be installed with chandeliers and bath bomb lamps, and there need to be reserved wire connectors, so the reserved wires should be well protected, and hoses should be used to protect them to avoid damage.

What should I pay attention to in the decoration of water and electricity in the house?

1. All joints are firm and reliable, and the sealing performance is good.

2. The outlet of the open water pipe should be cold at the top and hot at the bottom, hot on the left and cold on the right.

3. Before the indoor concealed pipeline is closed, the pressure test must be carried out. Generally, under the premise that the working pressure is not more than 0 6MPa, no decompression phenomenon is qualified.

4. The raw material belt at the interface between the faucet and the pipe fittings shall not be exposed.

5. The extension line on the outlet pipe fittings should be perpendicular to the wall.

6. The overall cast-in-place measures in the waterproof process generally require one cloth and three oils, or two cloths and six oils (cross paving).

7. The waterproof layer of the coating must be smooth and uniform, without peeling, shelling, cracks, bubbling and other defects.

8. The inspection method of waterproof engineering is to turn off the water for 24 hours without leakage, that is, it is qualified.

1. Do not destroy the original wire pipeline or plumbing pipeline when slotting and drilling. When laying electrical pipelines, it is necessary to thread the pipes, and do not bury the wires directly in the ground or wall, which is not only unsafe, but also cannot be repaired once damaged. The plumbing pipe must be pressed to test after it is laid, and then the next process will be done after passing the test to prevent damage caused by pipeline leakage.

2. Kitchens and bathrooms and other parts that need to be waterproofed must be tested for closed water after waterproofing, and then tiled after they are qualified.

3. The wire joints must be shabu-shabu, and the joints of the kitchen and bathroom are recommended to be waterproof, and the joints can be wrapped with high-pressure self-adhesive tape and black tape.

4. Lamps and lanterns weighing more than 3 kg must be fixed on bolts or embedded hooks, and it is forbidden to use wooden wedges to fix; The metal shell of the lamp with an installation height of less than one meter must be protected and grounded, and the bathroom must be waterproof socket.

5. The circuit construction must be standardized, for example, the wire pipe with a diameter of 16mm can wear up to 3 wires; Strong and weak wires should be more than 50cm away to avoid signal interference; The concealed conduit should be fixed firmly, otherwise the wall is easy to crack.
