Power lines are damaged quite often. In order to manage their work, reclosers were invented. How to use a recloser and what is it?
In simple terms, reclosers are high voltage devices. They have a huge impact on the operation of power networks, because very often emergencies and power outages occur. Today this is the main problem of energy. But with the use of reclosers, the situation has changed. They began to be installed on overhead power lines in order to regulate the work and prevent interruptions in the operation of the power grid. Without them, it would be difficult to control the operation of a long line.
After all, there are such sites that are located in hard-to-reach places, where it is difficult for a person to be in order to regulate the operation of networks.
Recloser - what is it?
These are indispensable devices. The interesting thing is that it takes them a few seconds to find the area where the failure occurred. Recloser can be used as a headswitch on distribution networks and points. Also with its help it becomes possible to connect other consumers. It also has the ability to diagnose errors. That is, if a problem occurs, it quickly finds the source of damage and blocks further violations.
Features
Every home has electricity. All facilities where electricity is present are difficult to maintain without special devices. With the advent of reclosers, the problem of maintaining electrical networks was solved. Because it is an intelligent switching device and does not need to be monitored. It independently controls the supply of electricity, as it has such an ability in its functionality. Therefore, such a high-voltage circuit breaker serves as the basis for the operation of the distribution network.
Functions
The most important purpose of a recloser is to protect 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 networks. As soon as an overload occurs, the electronic circuit feed switch is activated. After the work is established, the AC circuit is turned on. Such functions were incorporated into this electrical equipment from the very beginning. Therefore, the recloser works in accordance with the established 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;
- off emergency sections in automatic mode;
- turn on the power line automatically;
- determination of damaged areas;
- restoration of current supply in the areas operating in normal mode;
- gathering information about the mode of operation of power grids, their condition;
- interaction with the telematics system.
Features
The main component with which the device performs its tasks is a vacuum circuit breaker. It is needed in order to quickly determine where the short circuit occurred in order to correct the emergency operation of the power grid. 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:
- compact;
- easy to install;
- does not require special elements and fences;
- such devices do not need to be serviced;
- work is done automatically.
This is important in those areas that are difficult to reach, which allows you to restore the power 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 just differ in strength. The operating voltage is inrange from 6 to 35 kV.
Application
These devices make power grids "alive" as they react to every action. They can isolate a non-working area, while the work of other areas 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 supports fall. Recloser makes power supply reliable.
The production of such a device as a high-voltage switch is carried out by companies specializing in the automation of distribution networks.
About ten years ago circuit breakers were already used in our country. But they were not as common as they are now. Previously, to accommodate them, it was necessary to erect capital and modular buildings. As soon as vacuum devices began to be used, reclosers became small in size. As a result, their value has decreased.
With the use of new equipment and technologies, it was possible to expand the capabilities of reclosers, as they were not previously produced with automatic functions.
Today high-voltage circuit breakers are produced by the following companies:
- "Tavrida Electric" (Russia).
- Nulec Industries (Australia).
- Wipp&Burn (England).
These companies are engaged in the production of exclusively automatic devices.
Costdevices
What is the price of a recloser? The optimal cost for the devices was established 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 characteristics. They produce quality equipment that is in demand all over the world.
Thus, a recloser is equipment that ensures the uninterrupted operation of electrical networks. Without such devices, their functioning would be weak.
Therefore, they are simply necessary in different areas so that accidents do not occur in the operation of power lines. Therefore, it is now becoming clear what a recloser is and why it is highly valued, installed in most areas.
