High voltage lightning arrester is a very important device used to protect electrical equipment from the danger of lightning strikes. High-voltage arresters can be divided into many types according to their structure and application scope. This article will introduce the classification and different applications of high-voltage arresters, such as power systems, communication systems, buildings, etc.
Classification of high voltage arresters
1. Zinc oxide arrester
Zinc oxide arrester, also known as ordinary arrester, is the most common high-voltage arrester. Its main material is zinc oxide, which can conduct electricity when the voltage reaches a certain level, guiding the voltage to the ground. The advantages of zinc oxide arresters are low price, stable performance and suitable for low voltage systems.
2. Metal oxide arrester
Metal oxide arrester is a high-voltage arrester that uses metal oxide (varistor) as the main material. Its advantages are fast response speed, strong overvoltage resistance, and suitable for high voltage systems.
3. Radio interference arrester
Radio interference arrester is a high-voltage arrester specially designed to prevent radio interference. Its main material is organic polymer material, which has good radio interference suppression effect.
4. Gas discharge tube arrester
Gas discharge tube arrester is a high-voltage arrester that uses a gas discharge tube as the main component. Its advantages are fast response speed, strong overvoltage resistance, and suitable for high voltage systems.
Application scope of high voltage arrester
1. Power system
In power systems, high-voltage arresters are one of the most important devices to protect power equipment from lightning strikes. High-voltage lightning arresters are usually installed in transmission lines and substations to prevent lightning damage and failure to electrical equipment.
2. Communication system
In communication systems, high-voltage arresters are also very important. Communication equipment is usually installed on the top of buildings or high-rise buildings and is susceptible to the risk of lightning strikes. High-voltage lightning arresters can guide lightning to the ground and protect communication equipment from the danger of lightning strikes.
3. Buildings
In buildings, high-voltage arresters are also very important. Buildings often use lightning rods to protect the building from the danger of lightning strikes. A lightning rod is a special high-voltage lightning arrester that can guide lightning to the ground to prevent lightning from causing damage to buildings.
In short, high-voltage arresters are one of the most important devices to protect power equipment from lightning strikes. Depending on their structure and application range, high-voltage arresters can be divided into various types, such as zinc oxide arresters, metal oxide arresters, radio interference arresters and gas discharge tube arresters. High-voltage arresters are widely used in power systems, communication systems, buildings and other fields to protect the safety of equipment and personnel.
