The live testing instrument for zinc oxide lightning arresters has significant advantages in the power system, and its core values are reflected in multiple dimensions such as safety, efficiency, accuracy, comprehensive functionality, adaptability, and intelligence. The specific advantages are as follows:
1. Security advantage: No need for power outages, ensuring power supply continuity
① Live detection technology:
Traditional lightning arrester detection requires power outage operation, while live testers can complete the detection under normal equipment operation, avoiding power interruption caused by power outages, especially suitable for scenarios with high requirements for power supply reliability (such as hospitals, data centers, transportation hubs, etc.).
② Weak current design ensures personal safety:
The instrument adopts a weak current design internally (such as voltage not exceeding 12V), and the current and voltage sensors are completely isolated, completely eliminating the risk of electric shock for operators and complying with electrical safety operation standards.
2. Efficiency advantage: rapid detection, improving operation and maintenance efficiency
① Wireless synchronization technology:
By transmitting signals wirelessly (with a transmission distance of several hundred meters to several kilometers), long-distance cable connections are eliminated, reducing on-site wiring time, especially suitable for complex terrain or high-altitude work scenarios.
② Three phase synchronous measurement:
It can simultaneously measure the current and voltage parameters of three-phase lightning arresters, and complete the entire station detection with a single operation, which is more than three times more efficient than single-phase detection.
③ One click operation and quick results:
Some high-end models support automated testing processes, taking only a few minutes from wiring to generating reports, significantly reducing on-site operation time.
3. Precision advantage: Strong anti-interference ability, reliable data
① Digital signal processing technology:
By using harmonic analysis and digital filtering algorithms, effective suppression of on-site electromagnetic interference (such as harmonics generated by the operation of other equipment in the substation) is achieved, ensuring the accuracy of measurement results.
② Multi parameter synchronous analysis:
It can simultaneously measure parameters such as full current, resistive current, harmonic content (3-7 times), and power frequency reference voltage, and accurately determine the health status of lightning arresters through multi-dimensional data cross validation.
③ Angle compensation and anti-interference calculation:
Aiming at the mutual inductance interference between three-phase lightning arresters, the angle compensation algorithm is used to eliminate errors and avoid misjudgment, especially suitable for densely arranged substation environments.
4. Comprehensive functional advantage: One machine with multiple uses, meeting diverse needs
① Harmonic analysis capability:
Decompose the fundamental and various harmonic components in the resistive current to help identify different types of faults such as lightning arrester aging (increase in fundamental components) or moisture (increase in harmonics).
② Voltage free testing mode:
When PT signals cannot be obtained, the voltage reference is calculated through software algorithms to achieve "passive testing" and expand application scenarios (such as temporary maintenance or remote areas).
③ Data storage and export function:
Built in large capacity storage, capable of storing thousands of sets of test data, and supporting USB export or Bluetooth transfer to mobile phones/tablets, generating Word/Excel format reports for easy archiving and sharing.
5. Adaptability and intelligence advantages: Adapt to complex environments and assist in intelligent operation and maintenance
① Wide temperature and protection design:
The working temperature range covers -20 ℃ to 70 ℃, using dust-proof, waterproof, and anti-corrosion engineering plastic chassis, suitable for harsh environments such as high altitude, humidity, salt spray, etc.
② Battery life and flexible power supply:
The built-in high-energy lithium-ion battery supports continuous operation for more than 6 hours, and also supports external power adapters to meet the needs of long-term or different indoor and outdoor scenarios.
③ Intelligent diagnosis and predictive maintenance:
Some models are integrated with expert diagnostic systems, which can automatically analyze data and generate health assessment reports, predict the remaining life of lightning arresters based on historical data, and provide a basis for condition based maintenance.
6. Cost benefit advantage: Reduce full lifecycle costs
① Reduce power outage losses:
Live detection can avoid economic losses caused by power outages (such as industrial production interruptions and business activity shutdowns), especially suitable for high load periods or critical users.
② Extend equipment lifespan:
By accurately detecting hidden dangers in a timely manner, serious accidents such as explosions caused by faulty lightning arresters can be avoided, and the frequency of equipment replacement can be reduced.
③ Optimize operation and maintenance resources:
Wireless and automated design reduces the demand for on-site personnel and lowers labor costs; Cloud based data management enables remote monitoring and improves the utilization of operational resources.
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.
