Online Intelligent Monitoring System with Arrester
——The Arrester and Its Online Intelligent Monitoring System
Beijng Power Equipment Group is one of the national sentinel manufacturers of zinc oxide arresters. Since the Group cooperated with DOE Electric Power Research Institute and Xi'an Thermal Power Research Institute Co., Ltd, it has successively produced zinc oxide arresters with the 0.22kV-500kV voltage grade; put them in operation and received a good protective effect, obtaining the Science and Technology Progress Awards respectively issued by the state and the DOE in 1999.
The independently developed arrester online intelligent monitoring system is designed in accordance with the overall requirements of an intelligence of the equipment by intelligent substation construction of the State Grid Corporation of China. The system has changed the limit of the traditional arrester monitors or counters which require observing the running state of the arrester on site to judge. By collecting data on site and analog-digital conversion, the system will real-timely transmit the signals of the leakage current of the arrester running and action times to the online monitoring background through the optical fiber. The expert analysis software of the background according to the operation characteristics of the arrester automatically analyzes as well as judges the operation state of the arrester. Once a problem occurs, the software will immediately send alarm signals promptly to avoid a grid accident.
Main features of the Arrester Online Intelligent Monitoring System:
1. The online monitoring device adopts the joint supply scheme of special lithium battery and surge arrester leakage current. It avoids the need of connecting to other power source and the installation process has been simplified, ensuring the reliability of the online monitoring.
2. All the data is displayed and sent by digital values. Data accuracy is higher and more accurate and all the data is sent to the background to real-timely report the operation state of the arrester. The professional expert system of the background can analyze and handle a problem at any time as well as send an automatic alarm.
