Electrician of the 5th category. Electrician for repair and maintenance of electrical equipment

What is the profession of an electrician and what types is it divided into? What are the responsibilities of an electrician? The answers to these and many other questions will be given in the article.

Who is an electrician?

The light in the rooms is lit only thanks to electricians. If some electrical device fails, then, of course, the electrician is called for help again. Thanks to the representatives of the profession in question, constant quality control over electrical engineering is carried out. In Russia and other CIS countries, there is a severe shortage of workers. The country needs high-quality, competent specialists. That is why the profession of an electrician has long been highly demanded in the labor market. All are created the necessary conditions for employees: wages increase, optimization work environment, improving professional training- if only more people went into the profession.

And what does it prescribe about the representative of the profession in question production instruction for an electrician? This document establishes that the employee is obliged, if necessary, to assemble, install, mount, align, adjust or repair different kind electrical equipment and technical equipment. In addition, the employee needs to know the basics of electronics, the principles of operation of various mechanisms, the design of electrical appliances, etc. The complete list of disciplines that the employee should be aware of is regulated in detail by the production instruction for the electrician.

Job Responsibilities of an Electrician

The results of the surveys show that a person working by profession as an electrician should perform mainly physical work. The representative of the profession in question must have good, good health, a high level of endurance and excellent physical fitness.

If we talk about the duties of an employee, then everything will depend only on the category and qualifications of the worker. So, the production instruction for an electrician prescribes that an employee of 2-3 categories is obliged to wash parts and elements of various devices. Cleaning the contacts of electrical equipment is also the responsibility of a class 2-3 professional. Workers who have 4 or 5 categories are required to do more difficult and complex work. Accordingly, the responsibility of such specialists will increase markedly. Carrying out diagnostics of various hardware circuits - both electrical and mechanical, elimination of various kinds of problems and malfunctions - all this is included in the group official functions represented employee. Among other things, it is specialists of the 4th and 5th categories who are required to draw up various production sketches, drawings and diagrams.

It is also worth noting that she professional sphere includes more than 40 different subspecies. Each of them is an independent specialty, the basics of which are contained in a typical production instruction for an electrician. Next, the most basic and most common subtypes of this profession will be considered.

Rights and responsibilities of an electrician

The production instruction for an electrician assigns to a representative of the profession in question a number of specific rights and a group of criteria for which the employee must be responsible. It is worth noting that the entire list presented will not change or be cut in any way depending on the working category and function groups.

So, what are the rights of an electrician? Like most other working professionals, the person in question has the right to:

on the workplace, secured employment contract and other legal and regulations;
for timely and full wages;
to rest;
for safe work;
to provide him with all the information, as well as any plans, one way or another related to the work of electricians;
to participate in the management of the enterprise;
to protect their rights and much more.

Only the most basic professional rights of an employee were named above. What are the types of responsibility? Here are the most common types:

for the conscientious and high-quality performance of their labor functions;
for the internal order;
for labor safety;
for the careful attitude to the property of the enterprise and more.

Thus, the electrician's production instruction for the repair and maintenance of electrical equipment quite competently and clearly organizes all types of responsibilities and rights.

Electrician 4 category

An electrician of the 4th category is a very important person in production. That is why it is worth a little more to reveal the essence of his work. Since the general concept of the profession "electrician" has already been described, it will be necessary to refer directly to the duties of the employee. So, what do the production instructions for an electrician of the 4th category prescribe? What common features can be identified here? Here are the most basic ones:

Dismantling, timely inspection and repair of operated equipment.
Carrying out a full technical check upon completion of the repair.
Control over signaling - light and sound, over magnetic stations, control posts, etc. Timely elimination of various problems.
Carrying out work at power plants - departmental, transformer, etc.
Full control over lighting; timely troubleshooting on voltage lines.
Soldering.
Drawing up drawings and diagrams and performing work on them.

Electrician of the 5th category

Of the eight possible, an electrician of the fifth category is a rather important and valuable person in production. The production instruction for an electrician of the 5th category assigns the following duties to the employee:

dismantling, testing, repair, assembly and commissioning of high-voltage electrical machines and electrical equipment (up to 15 kV).
Work with automation and telemechanics: elimination of defects and adjustment.
Working with lighting and power plants with particularly complex switching circuits.
Work with cable networks with power from 35 kV.
Work with installations and mercury rectifiers, which are high-frequency.
Carrying out work with furnaces (steel-smelting, tunnel and blast furnace), with rolling machines, with welding equipment, etc.
Inspection, repair and commissioning of vacuum furnaces of a particularly complex type.
Works to identify, eliminate and prevent vibrations and noises in production that exceed the norm.
Carrying out work with flow transport lines, with feedback by voltage and current.

Of course, representatives of the profession in question with the fifth category can be endowed with many other functions. However, everything will depend on the company and place of work. The electrician's production instructions for the repair of electrical equipment involve a wide variety of functions and responsibilities.

About winding repair electrician

What is the work performed by the type of worker in question?
The production instructions for the winding repair electrician prescribe that a representative of this profession is obliged to identify defects, determine the volume and production labor activity associated with the repair of windings of the "monolith" type of any voltage with cooling - indirect or direct. This also includes one-piece winding and work on connecting parts of electric machines, testing windings for strength.

Above was presented a brief description of work performed. However, what examples of the work activity of the workers in question can be given? Here are the most common:

The old winding is dismantled and the new winding is installed on the rotors of turbogenerators and on large electric machines.
Carrying out similar work with generators that have water, hydrogen or oil cooling.
Working with centering and shroud rings on generator rotors.
Detection, repair and prevention of moisture leakage from the winding.

Of course, the representative of the profession in question is endowed with many other functions. However, they are all written in job description.

About the electrician for the repair of electricity meters

The electrician's production instruction for the repair and maintenance of electric meters assigns a number of rights, duties and responsibilities to the employee. Further, only the main functions of the presented employee will be described, since they will help to reveal the image of this specialist as widely as possible. So, what can be distinguished here?

In short, the employee is obliged to change electricity meters in a timely and high-quality manner. However, in addition to the replacement, the specialist is also obliged to deal with finances. It's about providing quality income. Money for the use of electricity from ordinary consumers. It is worth mentioning the documentation - almost no profession can do without it in our time. So, the electrician in question is obliged to draw up, draw up and submit to the management all the necessary papers on repairing the meters or replacing them on time.

In general, the work of the specialist in question is not much different from other types of electrical installation: elimination of defects, control over equipment, timely replacement of equipment, and much more - all this makes up the presented profession.

What is a GPM maintenance electrician?

To begin with, it is worth understanding what GPM is and how it stands for. Everything is quite simple here: these are load-lifting machines.
However, the question may arise: "What does an electrician have to do with it? What does he have to do with cranes at all?" The thing is that lifting equipment, directly connected to the network, has gone into oblivion many years ago. Today, driving machines of this kind will be very difficult. Needless to say, how important a person here will be a person who is able to diagnose the device, repair and service it. But the representative of the profession in question is just such a person. Without exaggeration, we can say that an electrician of this kind is probably the most prestigious specialist in his professional environment.

The production instruction of the electrician of the GPM assigns a number of duties to the employee. What are they? This will be discussed further.

Responsibilities of the electrician for the repair of the GPM

The duties of the employee in question are regulated by a special production instruction for an electrician. According to this document, almost all objects are subject to maintenance of the GPM.
The specialist himself must:

To keep all GPMs available in the production in optimal and working condition.
Conduct periodic inspections and checks of existing equipment.
Keep a journal of periodic inspection (typical for specialists with a certain category).
Eliminate emerging faults in a short or specified time.
Carry out work with experimental schemes of those. equipment of a particularly complex nature (adjustment, verification, repair, commissioning, etc.)
Working with instrument transformers (checking available accuracy classes).
Work with special pipelines, systems filled with various liquids (oil, gas, etc.)
Studying the working conditions of certain types of GPM; "practice development" - search for wear, elimination of defects and more.
Conducting briefing of employees, one way or another involved in the GPM.

Thus, the duties of a representative of the profession in question do not differ in anything special. The production instruction for an electrician for the repair of a PMG establishes the most common range of functions. Transferring responsibilities to a GPM environment certainly seems much more difficult. However, this complexity is easily offset by prestige.

Safety requirements during the work of electricians

Safety items are contained in the production instruction of the electrician. Maintenance of electrical equipment is given great attention in this document. But where greater value here has worker safety.
So, the instruction prescribes the following about the safety of specialists:

If an injured person is found, an ambulance should be called as soon as possible. At the same time, it is necessary to notify the leadership with the administration.
Troubleshooting work on the equipment must only be carried out with the power off.
Employees must keep their workplaces tidy and clean.
Documentation must be in perfect order at all times.
All information about the state of a particular piece of equipment must be logged.

Compliance with all of the above requirements will help to avoid accidents at work.
