Automatic lightning strike information lightning arrester for power transmission and distribution network

Abstract

The invention belongs to the power transmission and distribution network intelligent technical field in a smart grid and discloses an automatic lightning strike information lightning arrester for a power transmission and distribution network. The lightning arrester is composed of a lightning arrester body part 1 and a lightning arrester information part 2. According to the automatic lightning strike information lightning arrester for the power transmission and distribution network of the invention, a current sensor 31 acquires current signals; the current signals are connected to an information main processor 20 of the lightning arrester through a current processor 32 of the lightning arrester; when it is judged that warning is required to be performed, a communication processor 21 is activated to transmit signals to a power transmission and distribution management center; a power source acquisition circuit 22 obtains a power source from lightning strike; and the automatic lightning strike information lightning arrester arranges lightning strike address information in lightning strike warning information frames, so that a person in charge of the management of the transmission and distribution network can clearly know the location of a current network fault and can be facilitated to timely organize maintenance processing.

Description

[0001] a technical field [0002] The invention belongs to the technical field of intelligent power transmission and distribution network in a smart grid, in particular to an automatic lightning strike information lightning arrester for a power transmission and distribution network, which can enable relevant lines and equipment to realize automatic alarming of lightning strikes during operation, and realize automatic monitoring of lightning strikes by lightning arresters in the transmission and distribution network. information, automatic identification of lightning strike status and automatic alarm transmission. [0003] Two background technology [0004] Lightning arrester is a high-voltage electrical equipment component such as power transmission and distribution lines and insulators that absorb lightning overvoltage when struck by lightning, so as to protect these connected power transmission and distribution equipment from the overvoltage. [0005] One of the keys to the s...

Problems solved by technology

[0005] One of the keys to the safety of the power transmission and distribution network is the lightning arrester, which can effectively absorb the overvoltage of lightning strikes and protect the transmission and distribution lines and high-voltage equipment; Information; in order to grasp the lightning strike status of the power transmission and distribution network and the lightning arrester, people often add additional detection of lightning strike information, detection of the condition of the lightning arrester after lightning strike, and solve the power supply problem and remote communication problem of this detection, etc.
