Technical Field

The utility model belongs to the technical field of transformer iron core fixing components, and particularly relates to a clamp-on transformer iron core fixing component.

Background

The clamp-on transformer is a current measuring instrument, which is formed by combining a current transformer and an ammeter. The iron core of the clamp-on transformer can be opened when the wrench is tightly pinched, so that the lead wire through which the current to be measured passes can pass through the gap opened by the iron core without cutting off the lead wire. When the wrench is released, the core is closed, thereby securing the wire in the measurement position. The design makes the pincer-shaped transformer convenient to use, and can measure current without cutting off the lead.
