Embodiment Construction

[0018] figure 1 It is pointed out in the present invention—the whole of the automatic lightning strike information arrester for the transmission and distribution network, wherein the main part of the body 1 is a metal oxide arrester; the arrester information part 2 is attached to the arrester body 1, and the organic composition is below the body.

[0019] figure 2 The composition and connection method of the information part 2 in the automatic lightning strike information arrester of the present invention are described; the current sensor 31 collects the current signal flowing through the arrester and sends it to the current processor 32, and the current information of overcurrent or close to the threshold value is sent to the arrester information main The processor 20 starts the communication processor 21 to send to the background of the power transmission and distribution management center when it is determined that a current alarm is required.

[0020] The communication p...

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...
