Description

Technical Field

[0001] The utility model relates to the technical field of current transformers, in particular to a quick-install current transformer. Background Art

[0002] A current transformer is an instrument that converts a large primary current into a small secondary current for measurement based on the principle of electromagnetic induction. The current transformer is composed of a closed iron core and a winding. Its primary winding has very few turns and is connected in series in the circuit of the current to be measured. Therefore, it often has the entire current of the circuit flowing through it. The secondary winding has more turns and is connected in series in the measuring instrument and the protection circuit. When the current transformer is working, its secondary circuit is always closed. Therefore, the impedance of the series coil of the measuring instrument and the protection circuit is very small, and the working state of the current transformer is close to a short circuit.

[0003] However, it still has some disadvantages. For example, when using the quick-install current transformer, the traditional current transformer needs to be installed in the distribution box with the help of tools such as screwdrivers, the installation efficiency is slow, and the use of tools has certain limitations, which is not conducive to people's rapid assembly and reduces its convenience of use.
