How to learn how to learn an electrician step by step

Beginner electrician like this step by step learning:

1. Basic knowledge of electricians is the first step to get started. The basic knowledge of electricians includes: the basic principles of circuits, the composition of circuits, the use of electrical tools, electrical or electronic components.

The structure and function of three-phase electricity.

The origin of plant power distribution, power dragging, and electrician safety operating procedures.

Wait a minute. 2. Electrician is a very practical profession and must have hands-on ability. After mastering the basic theoretical knowledge, you must also participate in practice, and the electrotechnical technology focuses on hands-on ability, and can actually apply what you have learned, rather than moving your mouth.

3. Maintain an open-minded attitude and ask the master for advice. Electrician technology, no one will have the obligation to teach you, maintain an open-minded learning attitude in the work, encounter problems with the master, experienced people for advice, good at summarizing the problems encountered in the work and electrician skills can make you transform quickly.

4. Learn high-end technology in the later stage. Electrician is easy to get started, proficient but difficult, with a certain amount of work experience and theoretical knowledge, or to the development of high-end electrical technology, keep in mind a sentence: you will be something most people will, then you will be replaced with a high probability of being replaced, the salary is still not up, you will be something most people will not, the lower the probability of being replaced, the higher your value, the salary will naturally keep up.

1. Left zero and right fire.

2. The colors of the three-phase five-wire system are yellow, green, red and light blue respectively to represent the double color (PE) of the protective grounding wire.

3. During the operation of the transformer, the current of each phase of the transformer should not exceed the rated current; The maximum unbalanced current shall not exceed 25% of the rated current. After the transformer is put into operation, it should be overhauled regularly.

4. The rated voltage of the secondary coil of the voltage transformer is generally 100V.

5. The secondary side of the voltage transformer shall not be short-circuited when working. Because a large short-circuit current will be generated in the event of a short circuit, the transformer may be burned out, so fuses are installed on the primary and secondary sides of the voltage transformer for protection.

6. One end of the secondary side of the voltage transformer must be grounded. This is to prevent the primary and secondary coil insulation breakdown, the primary high voltage into the secondary side, endangering the safety of personnel and equipment.

7. The secondary side of the current transformer is close to the short-circuit condition when it is working. The rated current of the secondary coil is generally 5A.

8. The secondary side of the current transformer is never allowed to open the circuit when working.

9. One end of the secondary side of the current transformer must be grounded to prevent it.

When the insulation of the primary and secondary coils breaks down, the high voltage on the primary side enters the secondary side.

10. During installation, it must be noted that the wiring is correct and reliable, and the secondary side is not allowed to connect the fuse or switch. Even if for some reason the instrument or other device on the secondary side is to be removed, the secondary side must be shorted before it is removed.

11. Low-voltage switch refers to isolating switches, circuit breakers, fuses and so on below 1kV.

12. The load controlled by the low-voltage distribution device must be clearly divided, and it is strictly forbidden to control and confuse one gate.

13. The interlocking device of low-voltage power distribution device and self-provided generator equipment should operate reliably. It is strictly forbidden to run self-provided power generation equipment in parallel with the power grid without permission.

14. When connecting the equipment: connect the equipment first, then connect the power supply. When disassembling the device: disassemble the power supply first, and then disassemble the device. When connecting the line: connect the zero line first, then connect the live wire. When dismantling the line: dismantle the fire line first, and then dismantle the zero line.

Extended Material: Here's an introduction to how a novice electrician can start with the basics:

1. Basic knowledge of electrician, which is the basis for analyzing circuits.

2. Low-voltage electrical equipment, the key to understanding electrical equipment.

3. Electrical components and circuits, familiar with the components and circuit composition, and the cognition of electrical drawings.

4. Practical experience.

Electricians are not only skilled workers, but also special operations personnel, skilled workers with entry thresholds, and they are not just casual workers.

Electricians must be certified to work:

That is to say, it is necessary to take the electrician professional qualification certificate and the electrician operation certificate. The professional qualifications of electricians are divided into junior workers, intermediate workers, senior workers, technicians, and senior technicians. The higher the level, the better the skills and the stronger the problem-solving skills.

Electricians must have theoretical knowledge and operational skills

As an electrician, you must know the common sense of safe electricity use, motors and transformers, low-voltage electrical appliances, electrical and electronic technology, electrical control knowledge, and some PLC and other knowledge. In this way, you will be able to pass the theory exam.

At the same time, you must have the corresponding operation skills, basic wiring skills, installation and commissioning of basic circuits, installation and maintenance of basic electrical appliances, installation and maintenance of some electrical equipment and other operational skills. In order to pass the practical exam.

Therefore, electricians are not easy to be done, and electricians are skilled talents with high technical content.

Zero-based electricians should pay attention to: theory and practice, the direction of learning, familiarity with commonly used circuit components, and more analysis of simple introductory circuits. The details are as follows:

1. Electrician is first and foremost a technology, which needs to be affirmed, and electrician is a technology that combines theoretical knowledge and practical experience, and theory and practical experience are equally important.

Don't be overly inclined to practical operation, operation just makes the work at hand proficient and expands your horizons, but if you want to go further and higher, theoretical knowledge is essential.

2. Electrician beginners are recommended to learn the direction of PLC programming.

Inverter control, tension control, CAD design, DCS configuration, touch screen and other directions are all available, and it is also a relatively high-end electrical technology.

Familiar with the basic theoretical knowledge of electricians, such as single-phase electricity.

Three-phase electricity, household electricity, power supply, voltage, current, power, electric work.

and so on, to have a certain understanding of the basic theory.

3. Familiar with commonly used circuit components, such as: motors, air switches, leakage protectors.

Thermal relays, pushbutton switches, intermediate relays.

Speed relays, voltage relays, current relays, etc., are the basic skills necessary to understand circuit diagrams.

Learn about common electrical components and circuit symbols, such as AC contactors.

KM, intermediate relay ka, thermal relay FR, push button switch, circuit diagram are all this kind of circuit symbols, if you don't understand, you can't understand the circuit diagram.

4. Take a look at and analyze simple entry circuits, such as: jog control circuits, self-locking control circuits, forward and reverse control circuits, star triangles.

Step-down start-up circuit, etc., the most basic is often the most important, any complex circuit is composed of simple circuits, for example: most of the control circuits include self-locking circuits, proficient in basic circuits, complex can also be analyzed.

Presumably, people who are new to electricians learning circuit diagrams have a headache with these "strange" circuit symbols, one or two are fine, but there are countless categories of electrical symbols, once there are many of them, they are dizzy to remember, and learning is a process.

Knowledge needs to be precipitated, learn it once, then learn twice, learn it is your own, then for the students who can't remember, the teacher often says that "a good memory is not as good as a bad pen", we hold the paper and pen with our hands, copy it, the combination of the hand and the brain is double the memory, so maybe the inspiration comes, and occasionally one day suddenly finds that I remember.

If you want to be an electrician, you don't just pick up small tools such as wire strippers and do it brutely. Electrician is actually a technical job, to be an electrician, do maintenance, there is no shortcut, you can only learn steadily, while accumulating experience in the work. Or go to a professional training center to study hard.

Electricians are divided into maintenance electricians, on-duty electricians, construction electricians, etc., and the job categories are different, so the professional skills required also have their own emphasis, but as long as you are a professional electrician, you need to have the following basic skills.

The first is to know the basic common sense of electricians, mainly referring to the common sense of electrical safety, after all, electricians are often exposed to electricity is a high-risk occupation.

Second, it is professional skills, including line installation, installation and maintenance of commonly used low-voltage electrical appliances and power distribution devices, installation and maintenance of basic control circuits of motors, common sense of electronic circuits and so on.

If you are just a side electrician and only need to deal with some temporary glitches occasionally, then the professional requirements are a little simpler, you can use a voltage detector correctly, use a multimeter to measure voltage, current, resistance, and be able to replace the bulb and simple wiring yourself.

In short, God rewards hard work, and some technical work seems simple, but it is not a day's work to really master these things. If you want to achieve a promotion and salary increase as soon as possible, of course, the more knowledge you learn, the better.

At present, the employment prospects of electricians are very extensive, and the main work is concentrated in electricians, motor maintenance workers, electronic assemblers, power generation and distribution, relay protection, factory electricity, CNC maintenance, etc., and the demand for a large number of electrician talents makes electricians have broad employment prospects.

Electricians are actually very studious, and junior high school students can be fully competent after one to three months of training. Students often ask if they can still learn when they are 40 years old this year? Of course, the state stipulates that the age is 18-60 years old, and now the whole of China is in transition, and 60% of people who do traditional jobs have to change their careers and achieve employment only by learning new technologies and new skills!

The electrician profession does not worry about employment. Major enterprises, foreign-funded enterprises, power plant substations, power supply bureaus, properties, new energy vehicles, charging piles, photovoltaic power generation, high-speed railways, subway management and other employment enterprises are in urgent need of a large number of power-related talents.

As long as I like to study, it has little to do with my education level. Practice-based combined with professional learning. In a very short time, you will be able to master the repair technology. If you are bold and careful, you can succeed.

How to learn how to learn an electrician step by step

Generally speaking, if you want to engage in the electrical limb industry, it is recommended that you can go to a technical school or training institution to sign up and participate in formal electrician basic knowledge training and practical exercises.

In a formal electrician technical school or training center, after passing the study, practical operation and theoretical examination, you will have a power generation certificate and an electrician qualification certificate, and an electrician certificate will prove that you can engage in the corresponding electrical work, on the contrary, there is no electrician certificate in the work and engage in the electrical industry, which is not only an illegal operation, but also its own safety has not been guaranteed!

The basic knowledge of electricians includes: the basic principle of the circuit, the composition of the circuit, the use of electrical tools, the structure and function of electrical or electronic components, the origin of three-phase electricity, factory power distribution, power drag, electrician safety operation procedures, etc.

The accumulation of basic knowledge of electricians is very important, if the foundation is not stable or not strong enough, then the electrician's skills are not high, I have never heard that electricians do not make money, and I have never heard that learning basic knowledge of electricians is not important!

After mastering the basic theoretical knowledge, you must also participate in practice, and the electrotechnical technology focuses on hands-on ability, and can actually apply what you have learned, rather than moving your mouth. After obtaining the electrician certificate and participating in the work, you can learn while practicing at work, enrich your experience and hands-on experience, and learn while working, so that you can improve very quickly!

Learn how to learn electrician with zero foundation and learn quickly:

Electrician introductory basics, electronic technology and application, electrical diagrams, high and low voltage electrical components, common electrical tools, 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 and electricity saving, electrician common materials, 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, 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 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.

Beginners must start from the basic knowledge of electricians, and it is recommended to buy a basic professional book on electricians. You can also watch the blind teaching of some electrical engineering programs from universities on the Internet**. The basic theory is very important, and the various control theories of electrical power must be understood.

It's okay to master system theory in about a year.

If you are new to the electrician industry, you need to take the electrician certificate. The electrician certificate is now the entry certificate of the electrician industry, and if you want to engage in the electrician industry, you need to have an electrician certificate. At present, the training and certification time varies from place to place, generally about three months.

The course is different, the training content is different, and the final training time is also different, please choose the training course that suits you according to the specific arrangement of the training course.
