Description

Technical Field

[0001] The utility model relates to the technical field of differential-mode inductor core opening, in particular to a differential-mode inductor core air-gap opener. Background Art

[0002] Differential-mode inductance is a property of a closed loop. That is, when the current passing through the closed loop changes, an electromotive force will appear to resist the change of the current. This kind of inductance is called self-inductance, which is the property of the closed loop itself. Suppose the current of a closed loop changes, and due to the induction effect, an electromotive force is generated in another closed loop. This kind of inductance is called mutual inductance. An inductor is a circuit element specifically used in a circuit to realize inductance.

[0003] Chinese Patent Application No. (CN209843487U) discloses a differential-mode inductor core air-gap opener. Although this device can be opened and closed by two groups of paddles through a transmission mechanism, and can open the differential-mode inductor body in the placement groove, greatly improving the efficiency of traditional manual opening, the size of the opening of the differential-mode inductor body cannot be accurately controlled by the manual opening method. Therefore, the utility model provides a differential-mode inductor core air-gap opener to solve the above-mentioned problems. Summary of the Utility Model
