Description
Technical Field
The utility model relates to a current transformer field especially relates to a current transformer's current output pin structure.
Background
The current transformer is based on the principle of electromagnetic induction and consists of a closed magnetic core and a winding. The primary winding of the current transformer has few turns and is connected in series in a circuit of current to be measured, so that all current of the circuit always flows through the current transformer, the secondary winding has more turns and is connected in series in a measuring instrument and a protection circuit, and the secondary circuit of the current transformer is always closed when the current transformer works, so that the impedance of a series coil of the measuring instrument and the protection circuit is very small, and the working state of the current transformer is close to short circuit. The current transformer secondary side current output pin and the housing are manufactured in an integrated mode, and therefore the secondary winding is inconvenient to wire and assemble.
Disclosure of Invention
