Abstract

The invention provides an online monitoring and early warning system of a transformer substation oil-immersed transformer. Parameter information of an oil-immersed transformer, an AC / DC power supply screen and an oil switch is monitored through a transformer monitoring device, a voltage signal collecting circuit and an oil switch monitoring device respectively, and communication control connection with a computer is carried out through an MCU controller, so that the integral running state of the oil-immersed transformer system is conveniently controlled in time. The online monitoring and early warning system of the transformer substation oil-immersed transformer has the advantages of being scientific in design, safe, efficient, simple, convenient, economical and practical.

Description

technical field [0001] The invention relates to an on-line monitoring and early warning system, in particular to an on-line monitoring and early warning system for an oil-immersed transformer in a substation. Background technique [0002] Realizing intelligent online monitoring and early warning of substation oil-immersed transformers through smart grid automatic online detection technology is of great significance to the power system. Through online monitoring and early warning of substation oil-immersed transformers, it will greatly improve the safe operation of transformer equipment. At present, the main transformer equipment of the substation in operation cannot be detected online in real time, and it is basically repaired and repaired only when there is a fault, which not only affects the quality of power supply, but also increases the damage rate of the equipment. In addition, how to reduce costs is also a crucial issue if the transformation of intelligent online monit...
