Abstract

The invention discloses a disc type dragging and power generation integrated pulse power supply system, belongs to the technical field of inertia energy storage pulse power supplies, and aims to solvethe problems of long shafting, large vibration and noise, low system compactness, low energy storage density and low power density due to the fact that two motors are axially arranged at present. A conical bearing is arranged in a fixed platform, a ball bearing is arranged in a fixed device, and a rotating shaft is fixed on the conical bearing and the ball bearing; and upper air gaps are formed between the rotor and the upper stators, the number of the upper stators and the distance between the upper air gaps are respectively adjustable, and lower air gaps are formed between the rotor and thelower stators. An energy storage flywheel is fixed on the rotating shaft, and a permanent magnet is arranged on the surface of the energy storage flywheel; the compensation element is arranged belowthe permanent magnet; a rotor bandage is wound on the surface of a compensation element; the rotating shaft penetrates through a central hole; an armature winding is placed on a stator yoke, and is adischarge end; and the motor stator winding is wound on the stator yoke, and the motor stator winding is a charging end. The beneficial effects are that the charging speed is adjustable, and discharging is protected.

Description

technical field [0001] The invention belongs to the technical field of inertial energy storage pulse power supply. Background technique [0002] High-power pulse power supply can provide short-term strong pulse current, which has important applications in military, semiconductor, industry, environmental protection and other fields; pulse generator based on inertial energy storage is a special synchronous generator, using compensation principle and magnetic Through the compression principle, the internal inductance of the armature winding is greatly reduced, thereby obtaining a pulse current with a very high amplitude, which has great application potential. [0003] The existing generator system is driven by a separate prime mover (motor). The generator and the motor are arranged axially and connected by a coupling. The shaft system of the whole system is long, which is easy to cause vibration and large mechanical noise. It is difficult to disengage the engine and prime move...
