The live testing instrument for zinc oxide lightning arresters is a key equipment used in power systems to detect the performance of zinc oxide lightning arresters. Its application scenarios are wide, covering various aspects of power production, transmission, distribution, and equipment maintenance. The following is a detailed summary of its main application scenarios:
1. Daily inspection and status monitoring of power system
① Regular inspection of substations:
In substations, zinc oxide lightning arresters are important devices for protecting equipment from lightning overvoltage and operational overvoltage damage. The live tester can regularly detect lightning arresters without power outage, and can obtain key parameters such as full current, resistive current, harmonic content, etc. to evaluate their insulation performance and aging status.
Through long-term monitoring data, a health record of lightning arresters can be established, providing a basis for equipment condition assessment and life prediction.
② Transmission line inspection:
In transmission lines, lightning arresters are usually installed on towers or at the exit of substations. The live tester can conduct inspections along the line, quickly detect the performance of lightning arresters, timely discover potential faults, and avoid line tripping or equipment damage caused by lightning arrester failure.
2. Equipment maintenance and preventive testing
① Pre inspection before power outage maintenance:
Before planning power outage maintenance, using a live tester to pre test the lightning arrester can preliminarily determine whether it needs to be replaced or further repaired, thereby optimizing the maintenance plan and reducing unnecessary power outage time.
② Preventive testing:
According to the standards of the power industry, zinc oxide lightning arresters need to undergo regular preventive tests. The live tester can complete some test items, such as full current and resistive current measurement, without power outage, improving test efficiency and reducing test costs.
3. Fault diagnosis and localization
① Quick detection after malfunction:
When the power system malfunctions (such as lightning strikes, operating overvoltage, etc.), lightning arresters may be damaged due to overvoltage. The live tester can quickly detect lightning arresters, determine whether they are damaged, and provide a basis for fault handling.
② Fault location:
In complex power systems, fault location is often difficult. By detecting changes in the performance of lightning arresters, it can assist in locating fault points, narrowing down the scope of faults, and improving fault handling efficiency.
4. Testing in special environments
① High altitude areas:
In high-altitude areas, the air is thin and the insulation strength decreases, which may affect the performance of lightning arresters. The live tester can detect lightning arresters in high-altitude environments, evaluate their adaptability and reliability.
② Adverse weather conditions:
Under harsh weather conditions such as high temperature, low temperature, humidity, salt spray, etc., the insulation performance of lightning arresters may decrease. The live tester can detect lightning arresters under these conditions to ensure their normal operation.
③ Flammable and explosive places:
In flammable and explosive places such as chemical plants, oil depots, etc., power outage testing may pose safety risks. The live tester can detect lightning arresters without power outage to ensure safety.
5. Research and Teaching Applications
① Research experiment:
In power research institutions or universities, live testers can be used to study the performance changes and aging mechanisms of zinc oxide lightning arresters, providing data support for the development of new lightning arresters.
② Teaching demonstration:
In the teaching of electric power related majors, live testers can be used as teaching demonstration equipment to help students intuitively understand the working principle and detection methods of lightning arresters.
6. Smart grid and digital operation and maintenance
① Smart grid construction:
In the construction of smart grids, live testers can be integrated with intelligent monitoring systems to achieve remote monitoring and intelligent management of lightning arresters. By real-time transmission of detection data, lightning arrester faults can be detected and processed in a timely manner, improving the reliability and safety of the power grid.
② Digital operation and maintenance:
By combining technologies such as big data and cloud computing, the live testing instrument can achieve digital storage, analysis, and processing of detection data. By establishing a performance database and fault prediction model for lightning arresters, precise operation and predictive maintenance of lightning arresters can be achieved.
The ZC-710B zinc oxide lightning arrester tester is a specialized instrument used to test the electrical performance of zinc oxide lightning arresters. This instrument is suitable for live or power outage detection of zinc oxide lightning arresters of various voltage levels, so as to timely detect dangerous defects such as insulation moisture and valve aging inside the equipment.
The instrument is easy to operate and easy to use, and the entire measurement process is controlled by the human-machine interface. It can measure the full current, resistive current and its harmonics, power frequency reference voltage and its harmonics, active power and phase difference of the zinc oxide arrester. The large screen can display the true waveform of voltage and current. The instrument utilizes digital waveform analysis technology and software anti-interference methods such as harmonic analysis and digital filtering to ensure accurate and stable measurement results. It can accurately analyze the content of fundamental and 3rd to 9th harmonics, overcome the influence of phase interference, and accurately measure the resistive current of the side phase lightning arrester.
