Abstract
The utility model discloses a traction ventilator control system for a hybrid locomotive, which comprises a diesel generator set, a ventilation fan, a traction motor, a hybrid direct-current power source, an inverter, a microcomputer control system and traction current and temperature sensors. Alternating current generated by the diesel generator set is rectified by the hybrid direct-current power source into direct current to be stored in a storage battery, the direct current is inverted into three-phase frequency-adjustable alternating current by the inverter to be supplied to the ventilation fan, the ventilation fan transmits power to the traction motor by the aid of a three-phase alternating-current motor, the current and temperature sensors are disposed on the traction motor, and the microcomputer control system processes input signals of the current and temperature sensors and input signals of the inverter and controls the working state of the inverter. The traction ventilation fan control system for the hybrid locomotive has the advantages that the fan can run in different states according to different loads, energy conservation and noise reduction are realized, and maintenance cost is low.
Description
Technical field
The utility model relates to the control field, particularly a kind of hybrid locomotrives traction ventilator control system.
Background technique
The ventilator of existing electric locomotive traction motor generally adopts is the fixing control mode of rated speed, promptly runs under the rated speed as long as ventilator starts, and regardless of motor temperature, running current is much, and ventilator all consumes big power equally.
Existing electric locomotive auxiliary power supply all basically all adopts split-phase motor to convert single phase poaer supply to the three phase mains power supply, but noise is bigger when split-phase motor starts, and the three phase mains degree of symmetry is relatively poor, and efficient is not high, and power factor is lower.
More than the deficiency of two kinds of designs, all cause the loss of locomotive auxiliary power excessive, waste energy; The helper motor rate of fault is higher, increases the maintaining cost; It is bigger to make that simultaneously locomotive starts the operation noise, influences crew's working environment.
The model utility content
The goal of the invention of the utility model is: the problem to above-mentioned existence provides a kind of hybrid locomotrives traction ventilator control system.
The technological scheme that the utility model adopts is such: a kind of hybrid locomotrives traction ventilator control system; Comprise diesel generating set, ventilator, traction electric machine; Also comprise mixed power DC electrical source, inverter, Control System of Microcomputer and traction current and temperature transducer; The AC rectification that said mixed power DC electrical source sends diesel generating set becomes direct current and is stored in the storage battery; Be reverse into the Ac of three-phase frequency-adjustable and be the ventilator power supply through inverter then; Ventilator is given traction electric machine with three phase alternating current motor with power transmission, and said electric current, temperature transducer are arranged on the traction electric machine, and said Control System of Microcomputer is handled the input signal of electric current, temperature transducer and inverter and the working state of control inverter.
As optimal way, adopt IGBT in the said inverter as switching element.
As optimal way, said inverter has two covers, is connected in parallel between ventilator and the mixed power DC electrical source through an automatic transfer switch.
As optimal way, adopt the motor speed-regulating dsp chip in the Control System of Microcomputer.
As optimal way; Said motor speed-regulating dsp chip comprises gate pole control unit, AuCT unit, collecting sensor signal unit, inverter work monitoring unit, fault detection unit and the CAN EBI of power switch component, and the AuCT unit is through CAN bus and external relation.
In sum, owing to adopted technique scheme, the beneficial effect of the utility model is: can make blower fan according to different load operations in different state, energy-conservation, noise reduction; Adopt IGBT as switching element, can be according to pulse length modulation principle work, high switching frequency has reduced the harmonic wave of input output greatly, and it is basic identical with input voltage that input current can reach, and power factor is higher; Control System of Microcomputer can be sent control signal to the external world and also can receive extraneous signal and handle; The inverter of two parallel connections system that makes has certain redundancy; Guarantee therein under the situation that an inverter breaks down; Load can automatically switch on another inverter; Do not influence proper functioning, even two inverters break down, the merit operation still can fall in locomotive after the cut-out load; After out of order probability reduced, maintenance cost also reduced greatly.
