Description

Technical Field

[0001] The utility model relates to the technical field of transformer detection, and more specifically to a on-site detection device for 110KV transformers. Background Art

[0002] In order to measure the electric quantity in a large-current AC circuit, a current transformer is usually used to convert the large current into a small current, equipped with appropriate meters, and the transformation ratio relationship of the transformer is used for measurement. In addition, the transformer is also an indispensable device in aspects such as relay protection, automatic control, and signal indication of the power system.

[0003] The structural principle of the current transformer is similar to that of the power transformer. When the current transformer leaves the factory, corresponding detection equipment is needed for detection to ensure that the quality of the transformer is qualified. The current transformer detection equipment usually uses a loading fixture to install and fix the current transformer for easy detection. The 110KV transformer is cylindrical and has a long length, which is not convenient for fixing. The existing loading fixture has a simple structure and insufficient clamping stability, resulting in the current transformer being prone to looseness and offset on the loading fixture during the detection process, affecting the accuracy of the detection result and reducing the detection stability of the detection equipment.

[0004] Therefore, there is an urgent need for a on-site detection device for 110KV transformers. Summary of the Utility Model
