Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a digital remote meter for high-voltage power transformers. Background Technology

[0002] High-voltage power transformers are crucial core equipment in power systems. They are mainly used to raise or lower AC voltage to achieve efficient transmission and rational distribution of electrical energy. At the generation end, they can raise the lower voltage output by the generator to reduce power loss during transmission. At the consumption end, they can lower the high voltage to a voltage level suitable for the user. Their structure is complex and includes key components such as iron core, windings, and oil tank.

[0003] High-voltage power transformers are core equipment in power systems, and their operational status monitoring is crucial to grid safety. In traditional monitoring systems, parameters such as transformer oil temperature, oil level, and winding temperature are mostly displayed using mechanical or analog instruments. Maintenance personnel need to conduct regular on-site inspections and manually record data, which is inefficient and makes it difficult to detect potential problems in a timely manner. Nowadays, with the continuous development of smart grids and digital substations, new requirements have been placed on equipment status monitoring. It is necessary to achieve real-time monitoring of equipment status, remote data transmission, and intelligent analysis to quickly and accurately grasp the transformer's operating status and ensure the stable operation of the power grid.

[0004] Therefore, to address the above problems, a new digital remote meter for high-voltage power transformers is proposed. Utility Model Content
