Product Introduction

The construction of smart substations is an important part of State Grid Corporation of China's modern equipment management system, an important measure to improve the level of equipment intelligence and the quality and efficiency of substation operation and inspection, and an important foundation for the digital transformation of the substation profession. At present, in the process of promoting the construction of smart substations, four new technologies and applications, namely pointer type lightning arrester monitors, one key operation control, comprehensive monitoring of main and auxiliary systems, and remote intelligent inspections, are relatively mature and particularly recognized by the grassroots.Pointer type lightning arrester monitorIt is one of them. From the perspective of operation and maintenance performance, the manual on-site copying of meter values is a complex, inefficient, and repetitive labor. Through digital remote transmission, the digital collection and remote transmission of instrument data from the main equipment of the entire station will be realized, which will greatly reduce the daily operation and maintenance workload, effectively reduce the workload of operation and maintenance personnel, and significantly improve the operation and inspection performance. From the perspective of lean operation and maintenance, it is possible to achieve continuous monitoring of equipment, realize trend perception and sudden variable monitoring of data, which is conducive to lean operation and maintenance of equipment and will more effectively ensure equipment safety. The pointer type lightning arrester monitor has the product characteristics of precise data sensing, safe and efficient transmission, stable and reliable operation, and convenient maintenance. The pointer type lightning arrester monitor can monitor the full current and discharge frequency in real time, with pointer meter display and electromagnetic counter functions, as well as data remote transmission, alarm and data storage functions. The installation method of this product is the same as that of traditional electromechanical leakage current monitoring devices, which is easy to install and maintenance free.

Product Features

1. High precision measurement: Advanced sensing technology and signal processing algorithms are used to ensure the accuracy and stability of measurement data.

2. Remote transmission: Supports multiple communication protocols (such as Modbus, RS485, Ethernet, etc.) to achieve remote real-time monitoring and recording of data.

3. Multi functional display: Equipped with a LCD screen, it can intuitively display various measurement data and alarm information.

4. Strong reliability: Using high-performance components and materials, it has good anti-interference ability and long-term stable operation performance.

5. Easy to maintain: The structural design is reasonable, making it easy for daily maintenance and troubleshooting.

Product features

1. Automatic monitoring function: It can periodically automatically monitor the full current, number of actions, and action time of the lightning arrester.

Wireless communication function. This function is mainly for the LoRa wireless communication function of the lightning arrester monitoring device. Upload the characteristic data of the lightning arrester to the station aggregation node device through LoRa communication, and complete the data upload every 5 minutes.

The LoRa communication of the device complies with the "Q/GDW 12020-2019 Transmission and Transformation Equipment IoT Micro Power Wireless Network Communication Protocol" and can be directly connected to the perception layer of the transmission and transformation IoT without the need for other configurations.

2. Local display function: The lightning arrester action count is displayed using a 3-digit electromagnetic counter. The full current is displayed on a scale (the scale range can be configured). The scale has a normal area (green), a caution area (yellow), and an alarm area (red).
