Background
Current transformer (Current) Transformer short for CT): the device is an electric device which converts a primary current with a large line value into a secondary current with a small value through a certain transformation ratio according to the electromagnetic induction principle so as to carry out protection or measurement and other purposes. It is composed of closed iron core and winding coil. The transformation ratio of CT is essentially the ratio of the number of turns in the primary winding to the number of turns in the secondary winding.
Since the primary current is the line current to be measured, the value of the primary current changes according to the change of the load in different working periods, which may cause the following problems for the current transformer without reasonable adjustment of the transformation ratio: (1) the secondary current is too small, and the secondary loop is not enough to drive work, so that the measurement precision is not enough; (2) the secondary current is too large, and the electric secondary equipment is easy to burn out under the long-time working condition, so that the serious safety problem is caused.
Therefore, how to provide a structure capable of rotatably adjusting the transformation ratio of the current transformer, which not only saves manpower and material resources, but also avoids potential safety hazards caused by inconsistent three-phase transformation ratios due to misoperation, is a problem to be solved at present.
