Power lines are often damaged. In order to manage their work, reclosers were invented. How to use recloser and what is it?
In simple terms, reclosers are high-voltage devices. They have a huge impact on the operation of electric networks, because very often emergencies and power outages occur. Today this is the main energy problem. But with the use of reclosers, the situation has changed. They began to be installed on overhead power lines in order to regulate operation and prevent interruptions in the operation of electric networks. Without them, it would be difficult to control the operation of the line with a long length.
After all, there are such sites that are in remote places where it’s hard for a person to be in order to regulate the operation of networks.
Recloser - what is it?
These are irreplaceable devices. Interestingly, it takes them a few seconds to find the area where the failure occurred. The recloser can be used as a head switch on distribution networks and points. Also, with its help, it becomes possible to connect other consumers. He also has the ability to diagnose errors. That is, if a malfunction occurs, it quickly finds the source of damage and blocks further violations.
Specifications
Each house has electricity. All objects that have electricity are difficult to maintain without special devices. With the advent of reclosers, the problem of servicing electrical networks was resolved. Because it is an intelligent switching device, and it does not need to be monitored. It independently controls the supply of electricity, as it has such ability in its functionality. Therefore, such a high-voltage switch serves as the basis for the distribution network.
Functions
The most important purpose of a recloser is that it protects power lines from accidents. Because sometimes situations arise when the intensity of the current supply increases, that is, the lines are overloaded. A recloser helps prevent this process. It regulates the operation of networks. As soon as overload occurs, the electronic circuit breaker trips. After the work is established, the AC circuit is turned on. Such features were incorporated into this electrical equipment initially. Therefore, the recloser operates in accordance with the set sequence of cycles. In addition to the main function, the device performs additional, no less important. These include:
- implementation of instant switching in the distribution network;
- shutdown of emergency sections in automatic mode;
- turning on the power line automatically;
- identification of damaged areas;
- restoration of current supply in areas operating in the normal mode;
- collection of information on the mode of operation of electric networks, their condition;
- interaction with the telematics system.
Features
The main component with which the device performs the tasks assigned to it is a vacuum circuit breaker. It is needed in order to quickly determine where a short circuit occurred in order to fix the emergency mode of operation of electrical networks. What is a recloser? This is a device that is used for outdoor installation. Such equipment has features that distinguish it from other types of devices. These include:
- compactness;
- simplicity in installation;
- does not require special elements and fences;
- such devices do not need to be serviced;
- work takes place automatically.
This is important in those areas that are difficult to reach, which allows you to restore the current supply after an accident in sections of the power grid. If it is impossible to establish power supply, an information message is sent to the operator. As electrical and electromechanical equipment, a recloser can be compared to a circuit breaker, which is usually installed in the entrances of houses. They only differ by the force of tension. Operating voltage ranges from 6 to 35 kV.
Application
These devices make power grids “alive” because they respond to every action. They can isolate a non-working site, while the work of other sites will not be stopped. In the event of an accident, such a device immediately switches consumers to other power sources, even if a line break occurs or the supports fall. Recloser makes power supply reliable.
The production of such a device as a high-voltage switch is carried out by firms specializing in automation of distribution networks.
About ten years ago, circuit breakers were already used in our country. But they were not distributed as they are now. Previously, for their placement it was necessary to erect capital and modular buildings. As soon as they began to use vacuum devices, reclosers became small in size. As a result, their cost has decreased.
With the use of new equipment and technologies, it was possible to expand the capabilities of reclosers, since before they were not produced with automatic functions.
Today high-voltage circuit breakers are manufactured by the following companies:
- "Tavrida Electric" (Russia).
- Nulec Industries (Australia).
- Wipp & Burn (England).
These companies are engaged in the production of exclusively automatic devices.
Device cost
What is the price of a recloser? The optimal cost for the devices is set by the Russian company Tavrida Electric. The price ranges from 100,000 to 500,000 rubles. It all depends on the needs of the buyer and technical specifications. They produce high-quality equipment that is in demand around the world.
Thus, a recloser is equipment that ensures uninterrupted operation of electric networks. Without such devices, their functioning would be weak.
Therefore, they are simply necessary in different areas so that no accidents occur in the operation of power lines. Therefore, it is now becoming clear what it is - a recloser, and why it is highly valued for it, installing it on most sites.
