A current transformer current input terminal structure, adopt the structure of current input terminal spot welding rigid connection, it is more convenient to assemble, the intelligent production of being convenient for, and increase its accommodation.
Description
Technical Field
The utility model relates to a current transformer field especially relates to a current transformer current input terminal 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. Current current transformer once measures current input and adopts the wire to pass through the fixed direct access of screw and is surveyed the power, adopts the flexible coupling mode, and the assembly is troublesome, inconvenient realization intelligent production.
Disclosure of Invention
An object of the utility model is to provide a current transformer current input terminal structure adopts the structure of current input terminal spot welding rigid connection, and it is more convenient to assemble, and the intelligent production of being convenient for just increases its accommodation.
In order to achieve the above purpose, the utility model provides a technical scheme is: the transformer comprises a transformer housing, a coil and a wire, wherein the coil is clamped in the transformer housing, the wire is wound on the coil, a clamping groove is formed in the transformer housing, a clamping opening communicated with the clamping groove is formed in the transformer housing, current input terminals are clamped in the clamping groove and the clamping opening, and two ends of the wire are respectively welded at the inner ends of the two current input terminals in a spot mode.
The current input terminal is a copper sheet and is at a right angle.
The mutual inductor housing and the clamping groove are integrally formed by injection molding.
The utility model has the advantages that: the utility model provides a current transformer current input terminal structure, adopts the structure of current input terminal spot welding rigid connection, and the assembly is more convenient, the intelligent production of being convenient for, and increase its accommodation.
