6 FAQs about [Permanent magnetic circuit breaker energy storage]

Are magnetic device energy storage distribution relations constant?

According to the air gap dilution factor discussed in ampere-turns unchanged, magnetic induction intensity is constant, inductance constant several cases related to energy storage relationship, finally concluded that the magnetic device energy storage distribution relations.

How much energy is stored in a magnetic core?

Compare equations (36), (37), that the energy stored in the magnetic core is only 3.03% of the total energy, and the ratio of the energy stored in the magnetic core to the energy stored in the air gap is 1:32. It is verified that most energy is stored in the air gap during energy conversion of magnetic devices.

Does the storage energy distribution ratio of magnetic devices change after air gap?

The innovation point of this paper is to analyze storage energy distribution ratio on the core and gap of magnetic devices from the perspective of energy that the storage energy distribution ratio of magnetic devices is changed after the addition of air gap.

How does air gap affect magnetic energy storage?

Compare the magnetic core energy storage expression (9) with the total energy storage expression (14), it can be seen that the total energy increases by z-multiple after the addition of air gap, from Eqs. (16), (17) indicate almost all the energy is stored in the air gap, and the energy of magnetic devices expands and increases.

What is the total magnetic energy storage after air dilution?

According to Eqs. (11), (13), the total magnetic energy storage ( E) after air dilution is: (14) E = 1 2 B 2 A c L c Z u c = 1 2 B 2 A e L e Z u c When the air gap dilution coefficient Z = 1, Eq. (14) equal to (15) E = 1 2 B 2 A c L c 1 u c = 1 2 B 2 u c A e L e Compared Eq.
