Description
Technical field
The utility model relates to power frequency generating excitation controlling device, is specially the moving heavy section car power frequency generating of a kind of fax excitation controlling device.
Background technology
Because of site operation needs, the moving heavy section car brushless excitation main generator of fax not only needs for motor provides traction power source, and the three phase mains of AC400V/50Hz also need be provided for equipment such as engineering machinery and accident rescues when generating operation mode.
The control of microcomputer excitation is all adopted in the moving heavy section car power frequency generating of existing fax, and for example Chinese utility model patent specification CN201204563Y discloses a kind of like this microcomputer excitation controller.This kind control mode is to utilize microprocessor and software as control system, its advantage is the automaticity height, control is accurate, stable, reliable, but it is complicated that shortcoming is control, the cost height of controller, and have only the professional to keep in repair when control board breaks down, cause inconvenient maintenance and maintenance cost higher.
Summary of the invention
The utility model is in order to solve the control complexity that the control of the moving heavy section car power frequency generating of existing fax microcomputer excitation is brought, and problems such as cost height provide the moving heavy section car power frequency generating of a kind of fax excitation controlling device.
The utility model is to adopt following technical scheme to realize: the moving heavy section car power frequency generating of fax excitation controlling device, by mode switch with two grades of traction shelves and generating shelves, automatic voltage regulator and storage battery are formed, the generating shelves of mode switch comprise two switches, the output of described two switches links to each other with an ac input end with the dc power anode input of automatic voltage regulator respectively, the input that the positive pole of storage battery connects mode switch traction gear switch links to each other, and the negative pole of storage battery links to each other with the dc power cathode input of automatic voltage regulator.During use, the input of the switch that the output in the mode switch generating shelves is linked to each other with an ac input end and another ac input end of automatic voltage regulator are connected in fax and move on the output phase voltage of heavy section car brushless excitation main generator, and two outputs of automatic voltage regulator are connected in the excitation winding two ends of main generator.
Described automatic voltage regulator (being called for short AVR) is the ripe existing product of using.The working power of automatic voltage regulator can be and exchanges or two kinds of power supplys of direct current.If but automatic voltage regulator is separately working power with the storage battery in the utility model, then carry on construction work at night when locomotive, when illuminating lamp and control system power consumption are excessive, just can not guarantee that whole system normally moves; If automatic voltage regulator is a working power with the remanent magnetism voltage of main generator separately, its precondition is that main generator must have enough remanent magnetism so, like this could be after diesel engine drives generator and rotates, produce enough remanent magnetism voltage, to satisfy the automatic voltage regulator requirements of one's work, otherwise automatic voltage regulator just can't be worked, and also just can not send the required power frequency of construction certainly.For avoiding the generation of above two kinds of situations, the utility model has adopted mode switch, and (this mode switch has traction and generates electricity two grades, the generating shelves comprise two switches, the traction shelves comprise a switch, and the input of traction gear switch is connected with the input of one of them switch of generating shelves), during work, when pressing the generating shelves of mode switch, two switches in the generating shelves are closed simultaneously, so simultaneously with direct current and AC power input automatic voltage regulator, in the main generator initial start stage, with the storage battery is that automatic voltage regulator provides dc supply, when main generator was set up enough voltage, automatic voltage regulator inside by voltage ratio cut off DC power supply automatically, phase voltage with main generator is an AC power, satisfy the need of work of automatic voltage regulator, simultaneously also as voltage feedback signal, so that automatic voltage regulator is accurately controlled the power frequency supply of exciting current to realize that output is stable of main generator.When disconnection generating shelves, when pressing the traction shelves, storage battery provides field power supply for drawing generating.
The moving heavy section car power frequency generating of fax described in the utility model excitation controlling device adopts automatic voltage regulator and mode switch to realize the control of power frequency generating excitation, this control device has characteristics such as circuit is simple, output is stable, reliability is high, cost is low, and has solved the working power problem of AVR when main generator remanent magnetism is not enough.
