1, the inductance ballast 【 The inductance ballast, 电感镇流器) Is a core inductance coil, inductance is the nature of the when the current in the coil change, will cause the change of the magnetic flux in coil, thus produce inductive electromotive force, the direction and the change of the current in the opposite direction, thus hindering the current changes. 】 The structure of the
is a core inductance coil inductance ballast, the inductance of the nature is when the current in the coil change, will cause the change of the magnetic flux in coil, thus produce inductive electromotive force, the direction and the current in the opposite direction, thus hindering the current change, have the effect of limiting current.
2, inductance ballast is the theory basis of high voltage
the inductance ballast is produced from the theoretical basis of the high voltage coil self-induction phenomenon, namely, when the current in the conductor changes, conductor itself to produce induced electromotive force 【 When the coil ( A conductor loop) Still while the magnetic field changes, through the loop flux also produces change, thus stimulates in the loop of induction electromotive force is called induced electromotive force. 】 And the change of the electromotive force always blamed for the current in the conductor. This due to a change in the current conductor itself produces electromagnetic induction phenomenon, called self-induction phenomenon, the induced electromotive force in the self inductance phenomenon, called self-induction electromotive force. The size of the coil self-induction electromotive force related to self inductance, the longer the coil, the more the number of turns on the unit, the cross-sectional area, the greater the self-induction coefficient. With iron core coil self-induction coefficient, is much larger than without the iron core. By, we knew the inductive ballast in order to obtain a high voltage instantaneous and done the heavy sense.
