Job description for electrician 4th category. Job description for electrician for repair and maintenance

Choosing a profession is one of the most important decisions in the life of every person. If you initially want to connect your life with the electrical engineering industry, then not everything is so simple. In this field of human activity there are many different professions, one might say areas of activity, which have their own characteristic distinctive features. In this article we provide a brief description of the profession of an electrician for servicing substations.

First, let's look at what this profession is and what the responsibilities of an electrician in servicing substations are. Surely everyone knows about such an object as electrical distribution substation.

Why are substations needed? Distribution substations serve to receive electrical energy, convert it and distribute it to consumers or other substations.

At substations there is a large number of different electrical equipment and devices that ensure uninterrupted operation of this equipment and protect it from damage in case of emergency situations - power and instrument transformers, high-voltage switches of various types, disconnectors, load switches, separators and short circuiters, high-voltage fuses , arresters, capacitor banks, reactors, relay protection and automation devices.

In order to ensure reliable operation of this facility, it is necessary to constantly monitor the operating mode and, in the event of any deviations from the normal operating mode, take prompt measures to normalize it.

Therefore, substation maintenance is carried out by specially trained workers - electricians for substation maintenance. In order to understand who a substation maintenance electrician is, let’s consider his main responsibilities:

control over the operating mode of equipment. During his shift, an electrician constantly monitors the operating mode of both individual elements of equipment and devices, and the substation as a whole. It records the load on outgoing connections, supplying consumers or adjacent substations, voltage on buses of all voltage classes, frequency of the operating network; exercises control over various devices and devices (substation battery charging units, heating and cooling devices for equipment, communication devices, etc.);

elimination of accidents and technological violations;

implementation of operational maintenance of the substation: operational switching for operational purposes, as well as for removing equipment for repair;

participation in organizing the safe performance of work, in particular, carrying out work to prepare workplaces and allowing crews to carry out work on the territory of the substation.

Depending on the voltage class and the size of the substation, there are several ways to carry out maintenance of substations. If an enterprise has several small substations or substations where an automated control system is implemented, then servicing of these facilities can be carried out “at home”. That is, an electrician can be at home and, in the event of emergency situations or the need to carry out operational switching or other work, arrive at one of the serviced facilities.

If this is a large substation that supplies many critical consumers, then operational maintenance of this facility is carried out by permanent maintenance personnel. As a rule, substation maintenance is carried out by one electrician. At large facilities, where there is a large amount of equipment and a correspondingly large volume of work, there may be two operational workers per shift.

Each profession has its own nuances, which can only be learned in the process of work. I will depart from the generally accepted interpretations of this profession and tell you a little about this profession based on personal experience as an electrician servicing substations.

The first question that interests a person who has expressed a desire to work at an electrical substation as a service personnel is: how to get to the substation?

There is no highly specialized profession as an electrician for servicing substations in universities and technical schools. In order to work at a substation as maintenance personnel, in addition to having an electrical engineering education (in some cases, technical education in another specialty is permitted), it is necessary to undergo specialized training.

Many energy supply companies, which operate a large number of electrical substations, organize staff training at the enterprise itself. The employee undergoes specialized training in accordance with the approved program, internship and duplication directly at the workplace - at one of the substations (groups of substations) of the enterprise.

If the enterprise has several substations on its balance sheet and the number of service personnel is small, then organizing training at the expense of the enterprise is impractical. In this case, the management of the enterprise gives preference to those employees who have experience in operational maintenance of substations. Therefore, very often a person is faced with a problem: there is a job, there is an electrical engineering education, but without specialized training or experience they won’t hire him. What to do in this case? There are several ways.

The first is to undergo training at a specialized training center. If you have one, you can acquire practical skills in the profession of an operational worker.

The second method involves searching for an enterprise that provides training for personnel who service substations. It is possible that this enterprise will have working conditions that do not satisfy you, for example, distance from your place of residence, low pay, but at this enterprise you will be able to undergo training and gain experience as an electrician servicing substations.

Then, with the knowledge gained and experience (including that recorded in the work book, without which it is now difficult to get a job in the desired profession), you can move to a more prestigious job at another enterprise.

As for training in this profession, everything depends on the availability of education and work experience. If an employee has experience as an electrician servicing substations, then his training period is relatively short.

In this case, he needs to familiarize himself with the diagram and layout of the equipment of one or more substations, depending on the nature of the work (permanent maintenance personnel, maintenance of substations at home, work in an operational mobile team), and also receive (if available, confirm) the appropriate group for electrical safety.

If there is no experience in servicing substations, the newly hired employee undergoes full training according to a specialized program.

The future electrician gets acquainted with all the elements of electrical equipment, studies those installed at the substation, studies instructions for operational maintenance of the substation, emergency response, organization of work in electrical installations - in general, studies everything that he will encounter in the course of his work.

The final stage of training in the two above cases is an internship with subsequent duplication at the workplace, as well as testing the availability of practical skills in eliminating emergency situations and technological violations at the substation, which is one of the most important criteria for the readiness of an electrician to independently service the facility.

The profession of an electrician servicing a substation is interesting, intense and at the same time very responsible and dangerous. The main task of an electrician is to ensure the normal operation of the equipment and, accordingly, a reliable power supply to consumers, while observing all labor safety standards, in particular ensuring personal safety during the work process.

The complexity of the work and the amount of responsibility depend on the size of the substation and the category of consumers. If this is a small substation, for example, 35/10/0.4 kV, which supplies mainly consumers of the third category, then the work at such a substation is not varied and rich, as they say - peace and quiet.

If this is a large central substation that supplies critical consumers of the first category, as well as several adjacent substations, then you will not be bored with such work. Every day there is work - performing equipment repairs, turning off equipment to perform work at consumers, eliminating minor faults and, most importantly, monitoring the operating mode of the electrical network, which in turn affects the operation of the unified energy system of the region (region) as a whole.

Various emergency situations often arise: damage to one of the supply lines, equipment malfunctions and deviations from the normal operating mode of relay protection and automation devices, etc.

In addition, all elements of substation equipment are subject to periodic inspection and repair (routine, major repairs, troubleshooting in case of emergencies). The role of an electrician in servicing substations during repairs is one of the key ones. A substation maintenance electrician participates in organizing and carrying out work at a substation.

If it is necessary to carry out any work, the electrician’s task is to coordinate the removal of a particular piece of equipment or section of an electrical installation for repair with consumer enterprises.

Before the immediate start of work, the electrician must prepare the necessary switching forms to carry out operational switching to bring the equipment being repaired into repair. Next, the electrician takes the equipment out for repairs and allows the team to carry out this or that work on the territory of the substation.

You can often hear positive reviews of electricians who repair equipment, maintain relay protection and automation devices, and other workers who provide installation, repair, configuration, and testing of certain elements of equipment or devices. But not a word is mentioned about the electrician for servicing substations. In fact, preparatory work for repairs, that is, what an electrician does to maintain substations, is half, and in some cases, most of the work.

A specialist in servicing relay protection and automation devices checks the protection of one of the outgoing lines within an hour, and the entire process of organizing work (coordination, preparation for operational switching, repair and commissioning of equipment, permission to work and other work) in general complexity lasts several hours, or even more, depending on the specific situation and the role of the connection being taken out for repair at the substation.

For example, if it is necessary to repair the bus disconnector of one of the connections, then to perform this work it is necessary to take out the entire section (system) of buses for repair. In this case, the repair will be carried out within an hour or two, and the time required to remove the bus section (system) for repair and put it into operation, including preparatory work, will be 6-8 hours.

Thus, we can conclude that the profession of electrician for servicing substations is an important and responsible profession. This employee makes a significant contribution to the process of organizing the work of the energy supply company as a whole, which is comparable to the role of a specialist in equipment repair, communications and telemechanics.

Is there a prospect?

An equally important question is about the prospects of working as an electrician servicing substations. Many people probably objected, but is it worth spreading such an extensive story about such a, let’s say, not very noticeable profession?

If we are talking about an energy supply company, then the position of an electrician servicing substations may be the first step in a career at this enterprise.

There are several possible career options for a substation maintenance electrician. An electrician servicing substations is an operational personnel, so the next step in career growth may be a profession in the operational maintenance of enterprise facilities: dispatcher, senior dispatcher, engineer of the enterprise operational dispatch service.

Also, an electrician can go for a promotion in the substation service, where there are such positions as foreman, head of substation groups, site manager, substation service engineer and higher positions.

In the course of his work, the latter relies primarily on his theoretical experience, which was acquired at an educational institution, while an engineer who worked as an electrician servicing substations solves problems based on practical experience in servicing substation equipment, which is more effective, for example, when drawing up various projects of work in electrical installations of the enterprise.
