Description

Technical Field

[0001] The utility model belongs to the technical field of current transformers, and in particular relates to a current transformer with a protection structure. Background Art

[0002] A current transformer is an inductive device used to measure current. It winds a certain number of turns of the measured current through one side of the transformer, and induces an output signal proportional to the measured current on the other side. The main function of the transformer is to convert high current into low current for the convenience of measuring and protecting equipment. Current transformers are widely used in power systems to measure and protect high current equipment, such as transformers, generators and high-voltage lines. They can convert high current into small current suitable for measurement and control, thereby improving the safety and reliability of the power system.

[0003] Most current transformers on the market still have the following problems when used:

[0004] 1. The traditional current transformer may collide with other objects during use or installation. When a strong collision occurs, the transformer may be damaged due to the impact and cannot be used normally, and the anti-collision effect is poor;

[0005] 2. Most current transformers need to operate in different environments. Under high-load operation, the heat dissipated inside the transformer will be too high. Long-term high-load operation may cause the transformer to malfunction due to higher temperature, affecting the use of the transformer and poor temperature control effect. Utility Model Content
