Abstract

The invention relates to a transformer operation condition monitoring apparatus, specifically a transformer load monitor, and aims to solve the problems of high workload, time consumption and labor consumption and inaccurate data caused by manpower monitoring. The transformer load monitor comprises a transformer sampling circuit, an A / D converter, a CPU host module, a storage module, a U-disk read-write module, a GPRS wireless data transmission module, a display screen and a power supply module and the like; and the GPRS wireless data transmission module consists of a GPRS MODULE and an antenna interface connected with the GPRS MODULE, and also comprises a control module. The transformer load monitor can be widely applied to electrical equipment manufacturing, petrochemical engineering, steel metallurgy, railway electrification, and scientific research and teaching and other departments.

Description

technical field [0001] The invention relates to a transformer operating condition monitoring device, in particular to a transformer load monitoring instrument. Background technique [0002] With the deepening of power system reform and the implementation of "same network and same price" for urban and rural power grids, the operating risks of power supply enterprises are increasing, the industry advantages are decreasing, and the profit space is getting smaller and smaller. Each power supply enterprise can only tap the potential from within the enterprise, and reduce the line loss rate, improve power quality and power supply reliability by continuously improving the management level, so as to improve the economic benefits of the power supply enterprise. Among them, carrying out transformer load monitoring is one of the important measures to achieve the above goals. Moreover, as the electricity consumption of residents has also increased significantly, the transformer is ofte...
