On-line monitoring device for distribution transformer

Abstract

The invention discloses an on-line monitoring device for a distribution transformer, and the device comprises a main monitoring station, a signal receiving tower, a wireless connection network, a power distribution integrated tester, and an environment temperature tester. An output end of the signal receiving tower is connected to a signal input end of a main monitoring station, and a receiving end of the signal receiving tower is connected with a transmitting end of the wireless connection network in a mode of wireless signals. The power distribution integrated tester and the environment temperature tester are respectively provided with one signal transmitter, and the interior of the signal receiving tower is provided with a server which can store data. The beneficial effects of the invention are that the device achieves the on-line real-time monitoring, data collection, electric energy quality monitoring and reactive compensation control of the distribution transformer, and has remarkable effects for the management level of a power supply department, the power supply reliability and the operation economic efficiency.

Description

Technical field [0001] The invention relates to a monitoring device, in particular to an online monitoring device for a distribution transformer. Background technique [0002] At present, the distribution transformer is an important equipment of the distribution network, and its operation level has a significant impact on the development of the national economy and the improvement of the people's living standards. The distribution transformer has a large volume and a wide range, and its installation and operation are very complicated. During operation, there are often unqualified voltage quality, low power factor, and three-phase unbalance. In order to improve the safety, economy and power supply quality of the distribution system, it is necessary to monitor and manage distribution transformers. The monitoring of distribution transformers involves communication issues. Communication often becomes the bottleneck of this type of system, and there is a contradiction between reliabi...

AI Technical Summary

Problems solved by technology

The advantage of the digital transmission station is that apart from the annual frequency point fee, there is no additional cost for normal operation; the disadvantage is that the terrain and climate are greatly affected, resulting in poor system reliability and real-time performance, and cannot actively report

The GSM short message method can realize active reporting, but the disadvantage is that it is charged according to the article, the operating cost is high, and the short message center server is busy during holidays, and the time will be extended.

Optical fiber communication is stable and reliable, but the construction cost is large, the scalability is poor, and the equipment maintenance is inconvenient
