Abstract

The invention discloses a thyristor electromagnetic propulsion elastic feedback speed regulator of a direct-current generator. The regulator structurally comprises a thyristor magnetic push disc groove, a hanger folded plate, a cable, a clamp spring gasket, a torsion spring hanging cylinder, a shock-proof pipe and an emergency brake lifting and pressing plate. According to the invention, the cooperation of the thyristor magnetic push disc groove and the torsion spring hanging cylinder is realized; a current stabilization thyristor hanging bracket arranged in a convex groove shell is matched with the magnetic force regulation and control of a sliding block bracket to form a cuff shell core expansion node annular deceleration friction effect of an airbag frame column casing in a turntable body; after the speed regulation is finished, a cuff shell is contracted; the cuff shell is maintained and is wrapped by a short column casing groove; the stable rotation of the breakdown current is realized; the timely and synchronous operation can be carried out to adjust when the motor is overheated, the rate of diagonal torque reaches the elastic feedback effect of the electromagnetic propulsiontorsion spring hanging cylinder, the rotating precision is more flexibly matched and the pressure surface is reduced compared with rigid feedback, and the speed regulation working stability of the direct-current generator and the flexibility of real-time adjustment in cooperation with an elastic electromagnetic pressing rod are guaranteed.

Description

technical field [0001] The invention relates to a thyristor electromagnetic propulsion elastic feedback governor of a DC generator, which belongs to the field of governors. Background technique [0002] The rotation of the inner rotor shaft of the DC generator is guided by the transverse breakdown current of the multi-loop coil, which quickly spreads the electric heat during the power generation process, and also changes the working progress and current supply of the generator during speed regulation, which is convenient Deploy appropriate current and voltage values ​​for emergency power supply operations. The shortcomings of the current technology that need to be optimized are: [0003] The transverse breakdown current of the DC generator is often accompanied by the rotor coil to form a steady current rotation. During the speed regulation process, the angular velocity is adjusted by rigid feedback to the bearing wheel of the rotating shaft, which will cause a large friction...

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a thyristor electromagnetic propulsion elastic feedback governor of a DC generator to solve the problem that the transverse breakdown current of the DC generator is often accompanied by the steady current rotation of the rotor coil. During the speed regulation process, the rigid feedback of the bearing wheel of the rotating shaft to adjust the angular velocity will cause the friction coefficient of the tension rod and the flywheel ring disc brake to be large, and the loss will be serious. After long-term shear speed regulation, the disc brake plate will lose its toughness, which will cause The motor shaft and the speed regulating bearing ring form a slipping speed regulation phenomenon, which makes the speed regulation failure of the tie rod and causes the motor to overheat and rotate, which affects the heating degree of the motor rotor coil, thereby causing hidden dangers of leakage, and also causing the speed regulation feedback to be untimely.
