Electron stopping device

Abstract

The invention discloses an electron stopping device, which comprises a main generator, an exciter circuit and an output circuit, wherein the main generator is a separate-excitation DC generator; the exciter circuit comprises an excitation power supply, a correction resistor, a current-limiting resistor R', a compensation machine, a speed control relay and an exciting winding of the main generator; the excitation power supply, the correction resistor, the current-limiting resistor R', the compensation machine, the speed control relay and the exciting winding are sequentially connected in series to form a loop; the compensation machine and the excitation power supply are opposite in polarity; a contact group of the speed control relay controls the correction resistor and the compensation machine; an output end of the main generator is connected with the output circuit; and an input shaft of the main generator, the input shaft of the compensation machine and the input shaft of an AC generator in the speed control relay are driven by a drive shaft of an external power source. According to the electron stopping device, an exciting current of the main generator is changed through the compensation machine to prompt a great change of the output characteristic of the main generator; in the whole stopping process, the output electromotive force of the main generator can still be kept constant basically under the condition of monotonic decreasing of the vehicle speed; and the electron stopping device has relatively high energy conversion efficiency and relatively high output power.

Description

technical field [0001] The invention relates to the fields of electrical technology, electronic technology and the like, in particular to an electronic stop device. Background technique [0002] The essence of stopping is to convert all the kinetic energy of the object into other forms of energy. Generally speaking, the process of this energy conversion is the process that the moving object overcomes the external force to do work, and the performance of the stopper is determined by the actual situation of this work process. The common stopping device in reality is called "brake", which uses objects to overcome friction and do work to convert all kinetic energy into heat energy to achieve the purpose of stopping. The simple structure and obvious stop effect are the reasons why the "brake" device lasts for a long time. However, "brakes" also have many defects, such as worn-out machinery and the converted kinetic energy cannot be recycled again, especially the hard-to-control...
