Power semiconductor and electrohydrodynamic components of ore automated electric drives. Marenich K.N., Dubinka E. S.

The issues of adaptation of asynchronous frequency-controlled electric drives to the operating conditions in the structure of mechatron complexes of mountain machines, as well as mine batteries, contact and contact-accumulative electric locomotives are considered. Methods of suppressing the distortions of the sinusoidality of the voltage in the shaft of the power supply, caused by the operation of the frequency-controlled electric drives of mountain machines. The methodology for calculating the parameters of standard circuits of adjustable mine drives of alternating and direct current is disclosed. Features of the construction and operation of electro -hydrodynamic installations and linear engines in the structure of mining electric drives are considered. For students studying mining electrical engineering. It can be useful to engineers and technical workers engaged in power supply of mining enterprises.
