Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of CT installation, in particular to a CT assembly structure. Background Art
[0002] CT refers to a current transformer installed on a transformer, which converts the large current flowing through the transformer into a small current in proportion for measurement, metering, protection, and monitoring. Current transformers have a variety of applications in transformers, and they play a vital role in the protection, control, and monitoring of transformers. Using CT to monitor the current waveform of the transformer can diagnose internal faults of the transformer. When the current waveform is abnormal, it can be determined whether the transformer has a fault, such as poor contact, insulation breakdown, etc., by analyzing the abnormal waveform, so that timely measures can be taken to repair it and avoid further expansion of the fault. The application of current transformers in transformers is of great significance to the safe and stable operation of the power system. Before using the transformer, it is necessary to assemble the CT structure with practical bolts and other components to ensure that the transformer can operate smoothly.
[0003] Existing current transformers are widely used, but their assembly and disassembly require the use of tools such as bolts, which is rather cumbersome. In addition, current transformers release heat during use. When the current transformer is used at low intensity, the heat has little effect on the current transformer. However, when the current transformer is used at high intensity, a large amount of heat cannot be dissipated, which may cause damage to the current transformer. Therefore, a CT assembly structure is proposed to address the above problems. Utility Model Content
