Learn which power technology can be sent to the substation engineering company 20

The power transmission and transformation industry is actually the installation and commissioning of power engineering. It is mainly the erection of power transmission lines and the installation of substations. The few majors you mentioned are mainly used directly in power transmission and transformation companies.

I also work in a power transmission and transformation company, majoring in electrical engineering and automation. From the point of view of entry, the power transmission and transformation company does not have strong professional requirements, but the power engineering majors will not refuse; In the long run, it is recommended to choose the major of power plant and power system, which is more promising in terms of on-the-job examination and theoretical expertise.

ps: If you can, it is recommended that it is best to engage in power grid, power generation, power design and other industries, the power transmission and transformation industry is too bitter and the technical content is not high.

To be honest, these infrastructure units really don't want to go, I just came out of the power building.

After that, the market environment became more and more bad.

Now it's not a question of what you can learn to enter, but to send and transform power are directly to the school recruitment, you are not a major and have the opportunity to come in, but my brother advises you not to come to send power to the substation, it is very hard to run outside, you can't take care of your home, how many power transmission and transformation have no family conflicts? It's because I often don't go home, my wife can't stand it, and none of my colleagues around me have a family that can talk about happiness, brother, I'm from Jiangsu Power Transmission, tears are pouring out...

No.

The State Grid is not only a power supply company, but also a power transmission and transformation, provincial maintenance, electric power research institute, economic research institute, agricultural electricity, most people want to test the power supply company, don't be confused. The Electric Power Research Institute and the Economic Research Institute basically only need 985211 graduate students (a certain number of ** should be published every year) and the provincial maintenance is very tired (the operation personnel on the 500kV power pole) to send the substation construction unit, and travel to the construction site all year round (the advantage is that you can settle down in the provincial capital).

Of course, if you want to say that the power transmission and transformation is good, it also depends on the attitude of the provincial companies to their own power transmission and transformation, in the experience of doing the project and other power transmission and transformation communication, the mountain transmission is better, and the East China power transmission and transformation (that is, Shanghai power transmission and transformation but the name is East China), this depends on the post, in the company organs, if the ordinary office may be 9 to 5, in the company leadership, there may be a special power protection time to inspect the construction site, in the grassroots project department must not be off-duty, depending on the job position and the nature of the work.

Power transmission and transformation is a system composed of a network of transmission points formed by different voltage levels of power grids and substations connected to these voltage levels. Power transmission and transformation includes power transmission and substation power transmission mainly connects two substations in the use of substation for voltage regulation. The power transmission industry has power transmission and transformation companies in major provinces and cities, which are engaged in power construction ranging from 10kV to 100kv, mostly in the southern region.

For example, the formwork, sailing, Jinsu, and upward projects are the west-to-east power transmission projects in the national 12th Five-Year Plan. The upward is the start of the Xiangjiaba Hydropower Station in Yibin, Sichuan, and the termination of the 100kV transmission line in Shanghai.

1. The work tasks are different.

Power transmission engineering refers to the system work of transmitting electric energy, contacting various power plants and substations (stations) to run in parallel, realizing the networking of power systems, and realizing power transmission between power systems. Substation engineering refers to the system work in the power system that changes the voltage from low to high (boost) or from high to low (step-down) through certain equipment.

2. The work content is different.

The work content of the power transmission project is to transmit electric energy, and connect or transmit the electric energy to the designated area through the construction of elevated, electric wire and underground cable tunnel projects. In order to reduce the power loss and line impedance voltage drop on the transmission line, the substation project needs to increase the voltage or reduce the voltage in order to meet the safety needs of power users, and distribute it to each user.

Power engineering includes: power station (power generation engineering), transmission lines or transmission lines (transmission engineering or transmission engineering), substations (substation engineering), distribution lines (distribution engineering).

Power station: power supply, where electrical energy is produced; It is mainly based on 6-10kV voltage level.

Transmission line: complete the transmission and distribution of electric energy; The equipment is mainly from 110kV to 1000kv high voltage level;

Substation: change the voltage level to meet the needs of transmission and distribution, including low voltage and high voltage level;

Distribution line: distribute the electric energy to the user, mainly the medium and low voltage voltage level below 110kV.

Power transmission engineering mainly refers to the design and construction of transmission lines, including towers, wires, lightning cables, insulators, fittings, etc.

Substation engineering mainly refers to the design and construction of substations, including transformers, circuit breakers, disconnectors, busbars, lightning protection and grounding systems, relay protection systems, AC and DC power supplies, reactive power compensation devices, etc.

Power transmission engineering focuses on the transmission of electric energy, and substation engineering refers to the conversion of electric energy in substations (such as voltage boost and voltage reduction of electric energy).

General contracting of the overall construction of power transmission lines and substations of various voltage levels. First-level enterprises: can undertake individual Note: power projects include thermal power stations, nuclear power plants, wind power stations, solar power station projects, power transmission and transformation projects.

Line class The job responsibilities of the substation class. Substation includes, substation class and electric trial class.

1. Whether it is substation or power transmission, you need to travel, and the nature of the industry is determined, unless you are a clerical or relational person;

2. Substation is divided into civil engineering, equipment installation, commissioning, high-voltage test and other different classes, general civil engineering and equipment installation for the project department, this year newcomers will generally go to the commissioning and high-voltage test class, need to do their own work, physical strength is harder, the work cycle is more power transmission off, generally wait for the equipment to be installed before entering the site for commissioning;

3. The project department of power transmission is a management-oriented project, and the five members of the project cannot be missing, and the completion cycle of a project is long. It is more difficult to get started than substation, experience is more important, and there is more contact with people. Career growth is faster.

4. If there is no other company to choose, you have to enter the power transmission and substation industry, it is recommended to come according to your own personality, introverts can do power transformation; outward dry power transmission; This is my suggestion and is not authoritative.

What is the difference between the management type and the operation type of the transmission branch?

The construction technology of power transmission and transformation engineering is the installation and construction technology of high-voltage transmission lines and high-voltage substations

Regular pitch and pole position mileage.

Most of the tensile sections in the transmission line are composed of many continuous gears, which are called continuous pitches. Due to the limitation of topographic conditions, the length of each gear of the continuous gear and the height of the wire overhang point will not be exactly the same, in order to simplify the calculation of the overhead line stress in this continuous gear, an equivalent isolated gear is used to replace this continuous gear, and this isolated gear is called the representative pitch, also known as the regular pitch. It's a virtual pitch.

The pole mileage refers to the line distance between a tower and the starting pole position of the line, such as the line has a total of 100 base pole towers, wherein the pole position mileage of the 80th pole refers to the distance from the 1st pole to the 80th pole along the line, that is, the cumulative value of each gear from the 1st pole to the 80th pole. It can be used to quickly find out the length of the line at a certain base tower.

Installation and construction technology of high-voltage transmission lines and high-voltage substations.

Project manager: More than 50 million must hold a first-level constructor, and the rest can have a second-level constructor.

Chief engineer of the project: also need to have a certificate, without a certificate at least 15 years of work in the substation engineering technology: there are many kinds of certificates (such as technical personnel. Data clerk, etc.) engineering quality inspection: to have a quality inspector certificate.

**Group: Safety Supervision Group: Full-time Safety Officer Certificate, Supervisor Certificate, etc.

External Contact: Information Specialty, etc.

The above are indispensable for substation projects, you can refer to them, as well as the required certificates.
