Abstract
Description
Technical Field
[0001] The utility model relates to the field of clamps, in particular to a clamp used for a transformer core cutting device. Background Art
[0002] Commonly used transformer cores are generally made of silicon steel sheets. Silicon steel is a kind of steel containing silicon (also called silicon), and its silicon content is 0.8-4.8%. Silicon steel is used as the core of the transformer because silicon steel itself is a magnetic material with strong magnetic conductivity. In the energized coil, it can generate a large magnetic induction intensity, thereby reducing the size of the transformer. The existing cores are generally E-shaped, U-shaped or ring-shaped. When the ring-shaped core needs to be fixed, it is generally clamped from the inside. Such clamping equipment can generally only clamp ring-shaped cores of the same size, so it is not widely used. For this reason, we propose a clamp for the transformer core cutting device. Utility Model Content
