Embodiment Construction

[0024] Referring to the accompanying drawings, the zinc oxide lightning arrester wireless remote monitoring system includes an on-site acquisition module, a transmission and display module, and a remote monitoring center. The on-site acquisition module sends signals to the remote monitoring center to form data reports.

[0025] The on-site acquisition module includes a core processor, which is used for real-time detection of the resistive current of the arrester. The on-site acquisition module includes a MOA monitoring module, a current acquisition module, and a voltage acquisition module. The current data of the power line of the arrester under test is monitored by MOA The module is transmitted to the current acquisition module for collection. The output end of the current acquisition module is connected to an I / V conversion circuit. The power line voltage data of the lightning arrester under test is transmitted to the voltage acquisition module. The output end of the voltage a...

Abstract

The invention discloses a wireless remote monitoring system for zinc oxide arresters. The system comprises field collection modules, transmission and display modules and a remote monitoring center, wherein the field collection modules are used for sending signals to the remote monitoring center to form data reports and comprise core processors; the core processors are used for detecting resistivecurrents of the arresters in real time; the transmission and display modules are used for transmitting the data of the arresters, which are collected by the field collection modules, to the remote monitoring center, processing and displaying the data; and the remote monitoring center comprises information management system software and is used for carrying out data monitoring on the arrester states in real time and querying and analyzing the data. The system has the beneficial effects that a reasonable MOA (Metal Oxide Arrester) online monitoring model is constructed and interference sources can be removed to ensure that measurement results can accurately reflect the real operating states of the arresters; and by combining with GPRS (General Packet Radio Service) technology and the data collection terminal, the data are collected and transmitted to the remote monitoring center.

Description

technical field [0001] The invention relates to the technical field of electric equipment, in particular to a wireless remote monitoring system for a zinc oxide arrester. Background technique [0002] As the overvoltage protection device of electrical equipment, the performance of lightning arrester plays a great role in the safe operation of electrical equipment. In order to ensure the healthy and stable operation of power equipment, preventive tests are usually carried out. The power outage test requires a power outage, which has great limitations. The power outage cycle is long, the economic loss is large, and the labor efficiency is low. Moreover, a short power outage test finds equipment failures and cannot be fully dynamic. Guarantee that the equipment will fail again in the future. Moreover, if a fault cannot be detected in real time and effective measures are taken to deal with it, it will bury hidden dangers for the operation of the equipment. So the way to make u...
