Demand Analysis
In recent years, in order to reduce the transmission line lightning strike overvoltage caused by the breaker tripped, transmission line surge arrester plays a huge role, has been widely used, MOA surge arrester performance directly affects the safe operation of the power system. MOA surge arrester long-term in the role of high voltage at high frequency gradual aging in operation may occur breakdown damage, the protection characteristics of the decline, which will produce extremely serious consequences; in order to barrier MOA surge arrester safe operation, it is necessary to strictly monitor the MOA surge arrester, the protection characteristics of the surge arrester, and to ensure the safety of the power system. In order to prevent the safe operation of the MOA arrester, the MOA arrester must be strictly monitored.
Second, the principle of work
Transmission line surge arrester online monitoring system is our company for the power system needs and research and development of new high-tech products, equipment current detection using wireless telemetry monitor, to achieve the full isolation of no residual voltage sampling mode, the use of lightning arrester micro-current energy supply, will measure the results of the wireless transmission to the back office for the electric power personnel to view. This system is reliable and safe, affordable, so that the system can be installed to each group of MOA arrester for real-time detection, to complete the centralized monitoring, effectively improve the line arrester regulatory efficiency, to help the power sector to accurately and timely grasp the health of the operating equipment.
Functional characteristics
1, with the use of lightning arrester leakage current to take energy, without the use of power boards and lithium batteries and other power supply, to realize the monitor maintenance-free function;
2, full isolation without residual voltage sampling method, the lightning arrester does not have any impact on the work, effectively protect personal safety and equipment safety.
3, data collection power supply device using solar power and environmentally friendly lithium battery power supply, intelligent SOC control, to ensure that the local system of long-term reliable power supply requirements.
4, the interference problem has been fully considered, respectively, using a variety of effective anti-interference processing methods, to meet the requirements of normal use in a strong electromagnetic field interference environment.
5、Based on the GPRS/GSM network wireless data transmission mode, realizing "real-time, online, intelligent, remote" monitoring.
