Therefore, as relevant technicians of electrical engineering, they should carefully read the construction requirements and drawing arrangement before installing wires to avoid wire joint installation errors, The interface model does not meet the requirements of the whole project..
Key points of supervision technical disclosure is an important link in the construction process.
In the whole process of electrical engineering construction, in order to make all technical parameters meet the standards, engineering construction managers, supervisors, construction, design and other technicians need to invest more time and energy in the daily work process to study electrical construction technology.
The quality inspector must supervise the on-site construction personnel to construct in strict accordance with the drawings, and must also implement the “three inspection” system, that is, after each process is completed, the operation team shall first conduct self inspection, then the professional foreman shall conduct special inspection, and then the professional foreman shall organize relevant constructors, quality inspectors and technicians to conduct joint inspection.
The design drawings shall meet the requirements of the whole installation site, and put forward effective solutions according to the current situation of on-site construction.
At the same time, they can search the Internet for some relatively complete electrical technology videos and graphic materials, Through reading and learning to further deepen their understanding of electrical technology, and then integrate the most essential content into the on-site installation process, on this basis, often come to the site to observe the working state of each staff member.
Key points for optimization and design of low-voltage electrical installation and construction of construction engineering construction management personnel shall first seriously organize joint review of construction drawings in conjunction with supervision, construction, design and follow-up audit units to ensure the scientificity and rationality of electrical engineering design drawings.
Because the rear seats of ladder classrooms are raised, attention should be paid to the setting height of front lights in the design, so that students in the back row can not be disturbed by glare when looking at blackboards and screens.
During delivery, the acceptance certificate, product quality assurance, factory trial operation records and operation instructions shall be emphasized, and the key components such as leakage switch and air switch shall pass 3C certification; In principle, after the construction materials enter the site, at least 10% of them shall be randomly inspected.
In addition, under the conditions of different installation environments and different user needs, the complexity of low-voltage electrical installation is also strong, especially the projects such as wire and cable laying and lightning protection and grounding system belong to concealed works.
With the development of social economy, people pay more and more attention to their own quality of life, which requires the relevant workers in each professional field to work together, constantly explore the industry law, and constantly improve the technology and management level in practice.
The bottom edge of the power socket in the kindergarten place shall not be less than 1.8m from the ground.
The control range of lighting lines in teaching rooms should not be too large.
Fixing Socket Cross Hole Nail Plate
The on-site technicians must master all the contents of the construction design drawings and have insight into the key points and difficulties in the construction project.
In order to adapt to the development of the times, the field of electrical specialty needs to strengthen communication and communication in order to realize the balanced development of science and technology and society.
If there are quality problems, they shall be stopped immediately and replaced in time, and a special person shall track and record them, establish and improve the material account, strengthen the dynamic management of materials, stack materials reasonably, reduce secondary handling, and strictly enforce the material receiving and issuing system.
After the construction materials enter the site, Professional personnel shall also be arranged for on-site inspection and maintenance, moisture-proof and moisture-proof measures shall be taken, and signs shall be made to prevent quality discount due to improper storage.
Safe power sockets with safety shields must be used in primary and secondary schools, kindergartens and other campuses, mainly to prevent young children from touching the socket hole with their fingers or stabbing it with metal objects.
In order to improve the quality of the whole electrical project, in the process of designing drawings, we should first invest a lot of energy to understand the needs of the whole project in detail, and then design the most guiding drawings for the key contents of the project, To provide favorable technical support for on-site construction, designers must have a sense of responsibility.
In order to ensure that the overall quality of the project meets the standard, these small details should be paid great attention by all parties, and the installation quality of switchgear, measuring instruments and protective appliances should meet the industrial standards to ensure normal power transmission and distribution; When accurate values are needed, project supervisors should also take out corresponding tools to measure various indicators, and finally obtain reliable and accurate values.
At present, there are more than 1000 kinds of small household appliances in European and American developed countries, with an average of 20 ~ 30 small household appliances per household.
If there are problems, they shall be reported in time to determine whether it is necessary to modify the construction drawings of the whole project, so as to ensure the smooth progress of the later electrical equipment project and the efficient installation of electrical equipment, and determine the reliable connection of electrical components, We should also master the parameters required by various components, and remember that each index is controlled within the normal range when designing drawings.
For example, different schools and other industrial units, the seasonality of power consumption is obvious, except for winter and summer holidays, For safety and energy saving, generally speaking, there is a time period and space range that needs to implement shutdown and power-off management.
Take home appliances as an example.
The supervision is not in place.
The power control switch must also be set at the part that can only be controlled by teachers, so as to facilitate timely emergency treatment.
The supervision technicians should know the safety assurance system on the construction site like the back of their hands, check the qualifications of the contractor and personnel, and carry out electrician operation only with electrician certificate.
In the process of electrical engineering construction, the project supervision is not in place, resulting in lazy on-site operators, low construction efficiency and low quality, such as reverse connection of zero line and phase line, nonstandard cable binding, too large or too small distance between cables and other pipelines during wiring, and no cross grounding in order to save materials or drawings, The resulting campus electric shock and fire accidents have been numerous.
For teaching rooms with audio-visual teaching equipment, lighting lamps should be controlled in groups.
Any small mistake in the drawings may be infinitely enlarged in the construction project, resulting in the reduction of the safety and reliability of the whole project.
If the quantity is small, all of them shall be inspected.
If problems are identified, it should be pointed out in time, which can fundamentally avoid the appearance of quality problems.
Key acceptance points: the construction materials must be selected from reliable channels and suppliers with good market reputation.
The site details are not qualified.
Technicians shall provide necessary technical guidance and detailed description to the contractor, the supervision unit and representatives of on-site construction personnel on key processes, quality requirements and operation details.
Therefore, the construction supervision of electrical engineering needs to implement the whole process management to ensure the project quality and avoid potential safety hazards for daily operation and maintenance.
Therefore, generally, teaching rooms and non teaching rooms need to be designed with components to supply power, so as to ensure that the branches of different loads do not interfere with each other, so as to ensure their own power quality.
After human society entered the electrical age, the progress of production and lifestyle is changing with each passing day.
It is appropriate to have two to three classrooms.
Therefore, if the problem is not found at the first time, the project quality can not be effectively controlled, which often enlarges the problem infinitely, and finally affects the overall promotion of the whole project.
Common problems in low-voltage electrical installation and construction of construction projects unreliable drawings are the premise for the smooth development of the whole work.
For example, lines with different voltage levels or frequencies shall not be laid in the same conduit or slot box.
Residual current action protector shall be set for power socket circuit, electric water heater power supply and outdoor lighting power supply in campus buildings; Because naked lights produce glare, school classrooms must not be equipped with naked lights.
In the whole electrical construction process, there are many and more complex details.
During the construction of building electrical engineering, the installation of wires is a very important step, which will have a deep impact on the overall quality and effect of later projects.
