Lightning arrester action recorder

Abstract

The invention discloses a lightning arrester action recorder, which relates to the technical field of lightning arrester protection devices. The lightning arrester comprises a control unit, and a display unit, an input unit, an action detection unit, a clock unit, a radio controlled clock unit, a short time sending unit and a record storage unit respectively connected with the control unit. The radio controlled clock unit is used for automatic time correction, display time of the action recorder is enabled to automatically keep accurate synchronism with national standard time, thus, thunderbolt time can be recorded accurately each time, and accuracy of follow-up accident analysis and treatment is improved; the action recorder is also provided with a short time sending unit, information transmission is executed through a GPRS wireless transmission unit; and the GPRS wireless transmission unit has excellent real-time response processing capability, moreover, a transmission range is freefrom limitation of distance, transmission rate is high, power consumption is low, and the GPRS wireless transmission unit can continuously work for long time.

Description

technical field [0001] The invention belongs to the technical field of lightning arrester protection devices, in particular to a lightning arrester action recorder. Background technique [0002] The surge arrester is a kind of overvoltage protection device, which has become one of the important guarantees for the safe operation of the power system. The data transcription of the number of operations of the arrester during operation is an important basic work that needs to be carried out regularly in each substation. At present, most arresters can record the number of arrester operations, but the sensitivity to continuous lightning strike records is limited, and there are errors in the recording of precise time, which has a certain impact on the accuracy of accident analysis and processing. Accurately understanding the operation of the arrester during the processing process is conducive to quickly analyzing the accident situation and improving the efficiency of accident handli...

AI Technical Summary

Problems solved by technology

The traditional lightning arrester action recorder cannot automatically adjust the time, resulting in errors in the lightning strike time record, which affects the accuracy of accident analysis and processing

[0004] Based on this, the present invention proposes a lightning arrester action recorder, which uses a radio clock to automatically adjust the time, and can accurately record the time of lightning strikes; at the same time, it can count the number of lightning actions per month and the specific time of each lightning action, and analyze the measurement results and events. Information is historically stored to form accurate historical records, which solves the problem of errors in the recording time of arrester historical data in the past substation / converter station accident handling process, and simplifies the comparison and analysis of arrester historical data during the accident handling process for substation operators. It provides great convenience for substation operators to perform regular maintenance, equipment inspection and accident handling
