Magnetic core winding use how much!

Core winding is one of the ferrite core of common-mode interference suppression devices, it is made up of two same size, same number of turns of coil symmetrically on the same ferrite ring core, forming a four terminal device, to the common mode signal present a large inductance with inhibition, and for the differential mode signal showing a little small leakage inductance, magnetic ring used in balancing circuit can effectively inhibit common-mode interference signals ( Such as thunder and lightning interference) , and the line had no effect on normal transmission differential mode signal. The circular use in balancing circuit can effectively inhibit common-mode interference signals ( Such as thunder and lightning interference) , and the line had no effect on normal transmission differential mode signal. The core winding should be satiety when making the following requirements: 1) Magnetic core winding on the magnetic core coil winding wires to mutual insulation, to guarantee under the effect of transient overvoltage coil breakdown does not occur turn-to-turn short circuit. 2) When the instantaneous large current flows through the coil, don't appear saturated magnetic core. 3) Coil in the magnetic core and coil insulation to prevent under transient overvoltage between occurrence breakdown. 4) Should as far as possible winding coil monolayer, such doing can decrease coil parasitic capacitance, strengthen the circular coil the transient overvoltage and teaching ability.
