Abstract

The invention discloses a distributed wireless synchronous zinc oxide lightning arrester online monitoring apparatus. The apparatus comprises a cloud server, station wireless servers, lightning arrester leakage current acquisition units, reference voltage acquisition units, a network terminal and an onsite terminal. The cloud server is a bought or rented cloud-end server and runs lightning arrester monitoring management server software; each station wireless server comprises a wireless local area network access module, a radio frequency clock time service main station, a wireless mobile network communication module, a master control module and a battery; and the lightning arrester leakage current acquisition units and the reference voltage acquisition units each comprises a voltage transformer, a voltage signal conditioning circuit, an AD, a CPU, a GPS/BD clock time service module, a radio frequency clock synchronous module, a wireless network card, an antenna, a display screen and a battery. The apparatus provided by the invention is applied to online monitoring of the states of metal oxide lightning arresters, the work states of all the lightning arresters are uploaded to the cloud server through networks, and equipment states are checked through random networking of onsite terminals.

Description

technical field [0001] The present invention relates to a distributed wireless synchronous zinc oxide lightning arrester online monitoring device, in particular to a metal oxide lightning arrester online monitoring device for power system overvoltage protection, based on Internet and wireless communication technology for distributed power data collection, processing and analysis , The realization of the storage method belongs to the technical field of intelligent power transmission and transformation. Background technique [0002] Metal Oxide Arrester MOA is the most advanced lightning protection device recognized in the world. Due to the long-term influence of zinc oxide arresters on system voltage, overvoltage, pollution and internal moisture, the insulation performance is reduced, the nonlinear characteristics fail, and the MOA is aged and even exploded, which not only causes huge economic losses, but also seriously threatens the power grid. safe operation. Therefore, t...
