Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a carbon brush box. Background Technology

[0002] In the field of electrical equipment, especially in applications such as motors and generators, carbon brush holders play a crucial role in transmitting current to the rotor. They not only ensure stable current transmission but are also indispensable components for maintaining normal equipment operation. Meanwhile, the carbon brushes within the holder are consumable parts, and their wear directly affects the performance and lifespan of the electrical equipment. In actual operation and maintenance, operators often need to assess the degree of carbon brush wear and replace them promptly.

[0003] However, most carbon brush holders on the market use a closed structure, making it impossible for operators to directly observe the wear of the internal carbon brushes. This makes it difficult for operators to quickly and accurately determine the degree of carbon brush wear, and even more difficult to grasp the remaining lifespan of the carbon brushes. This may lead to equipment failure due to untimely maintenance, or unnecessary maintenance costs due to premature replacement of carbon brushes. Utility Model Content
