​In the operation of the power system, transmission lines serve as the main artery for energy transmission, and their safety and stability directly affect the reliable operation of the entire power grid. However, natural disasters such as lightning strikes frequently threaten the safety of transmission lines. As a key lightning protection equipment, the operation status of lightning arresters directly affects the protection effect of power facilities. The Jiuchuang brand has launchedJC-OM200AThe online monitoring device for lightning arresters in transmission lines, with its advanced technology and comprehensive functional characteristics, provides strong guarantees for the safety of the power grid. The following is a detailed analysis of the functional characteristics of the device.

1、 Real time monitoring and multi parameter acquisition

JC-OM200AThe online monitoring device for lightning arresters in transmission lines has real-time monitoring capabilities and can continuously collect multiple key parameters of lightning arresters, including but not limited to leakage current (full current), resistive current, capacitive current, lightning strike frequency, and lightning strike time. These parameters are important criteria for evaluating the performance of lightning arresters and determining whether they are operating normally. Through real-time monitoring, operation and maintenance personnel can timely grasp the status changes of lightning arresters, providing scientific basis for subsequent maintenance decisions.

2、 High precision measurement and data analysis

The device adopts a high-precision active zero flux through type transformer, which can automatically select the amplification factor according to the measured current, achieving high-precision measurement. At the same time, by combining dynamic phasor compensation algorithm and digital filtering algorithm, it effectively eliminates the interference caused by analog filters“Zero drift problem”This ensures the accuracy and stability of the measurement data. In addition, the device is equipped with an intelligent analysis system that can scientifically analyze and diagnose the collected data. By combining fitting processing with on-site working conditions, it can timely detect problems such as increased leakage current of the ceramic bushing or insulation rod caused by pollution or internal moisture in the lightning arrester, avoiding accidents.

3、 Wireless transmission and remote monitoring

JC-OM200AType device supportGPRS/GSMBy using wireless communication methods, real-time monitoring data can be remotely transmitted to the monitoring center, achieving centralized management and remote monitoring of data. Operations personnel can view the operation status and real-time monitoring data of lightning arresters anytime and anywhere through the backend terminal, greatly improving work efficiency and response speed. At the same time, the device also has an alarm function. Once an abnormality is detected in the lightning arrester, the system will immediately send an alarm signal to remind the operation and maintenance personnel to handle it in a timely manner, effectively preventing the expansion of the accident.

4、 Maintenance free design and strong anti-interference capability

The device adopts lightning arrester leakage current self power supply technology, abandoning the traditional power supply mode and achieving maintenance free operation. This not only reduces operation and maintenance costs, but also improves the reliability and stability of the device. In addition, the device also has strong electromagnetic interference resistance and can be used normally in strong electromagnetic field interference environments, ensuring the accuracy and completeness of monitoring data. This characteristic makesJC-OM200AThe type device can operate stably in various harsh environments, providing strong guarantees for the safety of the power grid.

5、 Modular design and flexible configuration

JC-OM200AThe type device adopts modular design, and each module samples the lightning arrester separatelyABCThree phase current or simultaneous acquisition of busbarABCThree phase voltage, while also collecting public power supply220VThe amplitude and phase of the data are used to provide comparative calculation data for the acquisition control unit. This design gives the device a high degree of flexibility and scalability, allowing for flexible configuration and upgrades according to actual needs. At the same time, the devices are interconnected through a bus, achieving centralized management and sharing of data, improving operation and maintenance efficiency and management level.

6、 Live installation and convenient access

Considering the convenience and safety of on-site installation,JC-OM200AThe type device supports live installation, which means that the installation work can be completed without the need for the main equipment to be powered off. This feature greatly shortens installation time, reduces installation risks, and provides great convenience for operation and maintenance personnel. At the same time, the device also has an automatic range switching function, which comprehensively guarantees measurement accuracy within the system range, ensuring the accuracy and reliability of monitoring data.
