Technical Progress of EBOW TYPE ARRESTER

EBOW TYPE ARRESTER is a high-performance electrical lightning protection device, widely used in power systems, industrial facilities and communication equipment, etc., to effectively protect equipment from lightning strikes. The arrester uses advanced technology and high-quality materials, which can quickly guide lightning current to flow safely into the earth when lightning occurs, thereby preventing power facilities and sensitive equipment from being damaged by lightning strikes.

Compared with traditional lightning arresters, EBOW TYPE ARRESTER has higher discharge capacity, stronger impact resistance and longer service life, and can provide long-term and reliable lightning protection in various complex environments.

Comparative Analysis of EBOW TYPE ARRESTER and Traditional Arrester

Working principle and performance difference

1. EBOW TYPE ARRESTER: Ituses high-performance semiconductor materials and advanced electrical design. It can respond quickly when lightning occurs, has strong discharge capacity, low leakage current and good overload resistance.
2. Traditional arrester: Traditional arresters such as zinc oxide arresters are usually based on zinc oxide ceramic materials. Although they have good nonlinear characteristics, their overvoltage absorption capacity and leakage current control are relatively poor. When subjected to extremely high lightning currents, traditional arresters may experience performance degradation or damage, resulting in system protection failure.

Durability and service life

1. EBOW TYPE ARRESTER: Ituses high-quality weather-resistant materials, has strong heat resistance, corrosion resistance and moisture resistance, and is suitable for long-term operation in various harsh environments. It has a long design life, usually more than 10 years, and has strong impact resistance, and can withstand multiple lightning shocks without performance degradation.
2. Traditional lightning arresters: Traditional lightning arresters, especially ceramic and some zinc oxide lightning arresters, are easily affected by environmental factors (such as temperature, humidity, corrosive gases, etc.), and may age, degrade in performance, or even fail after long-term use. In addition, traditional lightning arresters have a limited number of lightning strikes, and too many lightning strikes may cause damage to internal materials or structural ruptures.

Response time and protection performance

1. EBOW TYPE ARRESTER: The advanced electronic technology and fast response mechanism used in EBOW type lightning arresters enable it to start quickly before lightning arrives, and effectively shunt lightning current when lightning strikes, protecting power systems and equipment from damage. Its response speed is usually very fast, which can ensure the rapid absorption of instantaneous high voltage.
2. Traditional lightning arresters: The response speed of traditional lightning arresters is relatively slow. Although they can absorb lightning strikes, they may not react quickly enough when facing instantaneous overvoltage. Especially in areas with frequent lightning strikes, traditional lightning arresters may gradually lose their protection capabilities after lightning strikes.

Compared with traditional lightning arresters, EBOW TYPE ARRESTER has higher performance, longer service life, stronger durability, faster response speed and lower maintenance cost.

Maintenance and troubleshooting

Possible problems with EBOW TYPE ARRESTER

Performance degradation

Cause: Over time, the internal materials of the EBOW TYPE ARRESTER (such as semiconductor components) may be affected by lightning current, ambient temperature changes, moisture, corrosion and other factors, resulting in a gradual decrease in its ability to absorb lightning current. This performance degradation is often manifested as an increase in the arrester’s leakage current and a decrease in its discharge capacity.

Solution: Regularly test the arrester’s discharge voltage and response time to ensure that its performance meets the design requirements. If performance degradation is found, the damaged components or the entire arrester module should be replaced in a timely manner.

Internal damage or failure

Cause: In the event of a strong lightning strike or equipment overload, the EBOW TYPE ARRESTER may have an internal short circuit or open circuit. Severe lightning strikes may cause the internal components of the arrester to burn or permanently damage, affecting its normal operation.

Solution: In an environment with high-frequency lightning strikes, the EBOW TYPE ARRESTER may need to be replaced. Before that, regularly check the appearance of the arrester to see if there are obvious signs of burning or cracking, especially in seasons with frequent lightning activity.

Maintenance methods

Regular inspection and cleaning

Inspection frequency: It is recommended to conduct a comprehensive inspection every six months or before the lightning season. The inspection content includes the integrity of the shell, the grounding system, the status of the internal components, etc.

Cleaning steps: Use a soft cloth or low-pressure air to clean the surface of the lightning arrester, and avoid using corrosive cleaning agents. In humid areas, pay special attention to cleaning the grounding terminal of the lightning arrester to avoid affecting the performance of the equipment due to accumulated water and moisture.

Performance test

Test content: Conduct electrical tests regularly, especially testing the discharge voltage, leakage current and response time of the EBOW TYPE ARRESTER. These tests can help detect the working status of the lightning arrester and determine whether it still has sufficient protection capabilities.

Detection tools: Professional electrical detection instruments, such as high-voltage testers, ground resistance testers, etc., can be used to check whether the electrical performance of the lightning arrester meets the design standards.

FAQ

Q1: What places are EBOW TYPE ARRESTER suitable for?

A1: It is widely used in power systems, communication facilities, substations, power plants, industrial equipment, and residential and commercial buildings. It is suitable for various power facilities and high-value equipment, especially in areas with frequent lightning strikes, and can effectively prevent equipment damage and shutdown caused by lightning.

Q2: What are the installation requirements for EBOW type arrester?

A2: The installation of it should follow the technical manual and specifications provided by the manufacturer. Generally speaking, the installation location should be selected at the incoming line end of the equipment or near key power equipment to ensure that the arrester can effectively divert lightning current. During installation, special attention should be paid to the connection of the grounding system to ensure that the grounding resistance meets the standard to ensure the best performance of the arrester.

Q3: How to judge whether the EBOW type arrester needs to be replaced?

A3: If the EBOW type arrester is found to have performance degradation after multiple lightning strikes (such as increased leakage current, abnormal discharge voltage, etc.), or if external damage (such as burning, cracks, etc.) is found during inspection, it needs to be replaced. If the grounding system fails or the lightning arrester loses its ability to respond, it should also be replaced immediately.
