Description

 . d. f

4l;

where / fe is magnetic constant; i) is the number of turns of the inductive storage; d is its diameter; F is a coefficient whose value depends on the ratio of the length of the solenoid to its diameter.

The introduced inductance, due to the shielding of the inductive storage 9 located inside it a short-circuited coil 11, is

A L - 2 fi0 о R0F,

where RO is the average radius of the inductive storage; F is a coefficient whose value depends on the ratio of the radius R of the short-circuited coil 11 to the average radius RO of the inductive storage 9, as well as the ratio of the length of the inductive storage 9 to its average radius R0.

After closing the turns of the inductive storage 9, the current flows through the short-circuited coil 11 in contact with it, the shape of which remains close to the shape of a hollow cylinder. Therefore, the value is determined by the expression

where And is the length of the closed loop 11; R is its outer radius; c is a value depending on the ratio of the inner and outer radii of the closed loop 11.

Thus, a decrease in the inductance of the inductive storage 9 when its turns are closed leads to a decrease in the time constant and, consequently, to an increase in the discharge power.
