Abstract
The present application belongs to the field of rail transit technology, and particularly relates to a kind of calculation method and model of hollow coil inductance value of track circuit, for solving the problem that the geometric size of hollow coil itself is larger, if enough far place is selected as the boundary of field, the calculation amount of vector magnetic potential A is very large, the calculation time is long, and the calculation accuracy cannot be guaranteed.The present scheme selects a calculation field for the inductance of hollow coil, and gives the determination method of vector magnetic potential A on the outer boundary, reducing the calculation amount of inductance value.Compared with the prior art, the present application avoids the problem of too large outer boundary, the calculation amount of vector magnetic potential A is small, the calculation is fast, and the calculation accuracy is effectively guaranteed, which contributes to the stability of track circuit and the safe operation of train.
