Abstract

The invention provides a lightning arrester on-line monitoring device. The lightning arrester on-line monitoring device comprises a communication module, a light pipe module, a mutual inductor module,a power supply module, a main control module and a man-machine interaction module which are connected through a connection module; the communication module realizes internal Ethernet communication with the main control module and comprises a main RS485 interface, a standby RS485 interface and an IRIG-B interface, the two RS485 interfaces are in communication connection with a monitor, and a mainport is automatically switched to a standby port in case of failure; and the IRIG-B interface is used for receiving a B code timing signal. According to the invention, multiple functions of acquisition, communication, event recording and the like are integrated; the device not only can be used for recording leakage current and action times (with action time) in real time, but also can be used forcollecting optical pulse action signals of the monitor and carrying out action time statistics and action event recording.

Description

technical field [0001] The invention relates to the field of monitoring devices, in particular to an online monitoring device for lightning arresters. Background technique [0002] The arrester online monitoring device is an instrument used in conjunction with the zinc oxide arrester in the high-voltage AC power system, and the instrument is connected in series in the grounding circuit of the arrester. The milliampere meter in the monitor is used to monitor the leakage current (peak value) passing through the arrester under the operating voltage, and can judge whether the interior of the arrester is damp, whether the components are abnormal, etc. The existing on-line monitoring devices for arresters have single functions and limited conditions of use. Contents of the invention [0003] In order to solve the problems of the prior art, the present invention provides an online monitoring device for lightning arresters, which integrates multiple functions such as collection, ...
