An online monitoring system for environmental parameters of power distribution network box type transformer

Abstract

The invention relates to a power distribution net box type transformer environmental parameters on-line monitoring system which includes the steps that aiming at any one of box-type transformer substations, the power distribution net box type transformer environmental parameters on-line monitoring system is provided with a plurality of sensors, wherein at least the temperature of a high pressure charged body in the environmental parameters of the box-type transformer substations, the high frequency partial discharge, the temperature and humidity in the box-type substation are monitored correspondingly by the sensors, and the monitored data of the various sensors are received and sent to a front-end data acquisition unit of a monitoring center based on a wired or wireless communication mode. The data processing server device of the monitoring center carries out the storage and processing analysis for the received data to generate a real-time dynamic monitoring curve and produces an audible and visual alarm when the monitored data exceed a set threshold value, and meanwhile the alarm information can notify attendants in the relevant areas in a text message form, so that the time of incident response is shortened and the economic loss is reduced.

Description

technical field [0001] The invention relates to the technology of on-line monitoring and condition maintenance of electric equipment, in particular to an on-line monitoring system for environmental parameters of a power distribution network box-type transformer. Background technique [0002] With the increasing scale and complexity of the power grid, the substantial increase in transmission capacity and the increase in voltage levels, the efficiency of power transmission is getting higher and higher, the investment in power grid equipment is getting higher and higher, and the direct and indirect losses caused by sudden failures are also increasing. The bigger it is, how to avoid and reduce losses becomes a very prominent issue. For this reason, the maintenance of power grid equipment has gradually developed from accident maintenance to regular maintenance, and then to condition-based maintenance based on reliability. [0003] Since the 1960s, the United States began to carr...

Problems solved by technology

Due to the scattered installation locations of box transformers, it is difficult to set up communication lines, and it is difficult to inform the management personnel of information such as changes in its operating status, fires caused by temperature rises, short circuits caused by rain, and theft in a short time, resulting in longer power outages and even Phenomena such as transformers being stolen and burned occur from time to time
