Description
Technical field
The utility model relates to field transformer, especially a kind of traction transformer.
Background technology
Along with the growth year by year of electric railway freight volume, the traction transformer overload situation of traction substation is day by day serious, under current railway transportation environment, should ensure that the security of operation of traction transformer guarantees transport task again, particularly important to the overload research of traction transformer.On the basis to the statistical analysis of traction transformer overload protection action behavior, obtain the reason of overload protection frequent movement tripping operation, and propose corresponding resolution policy.In recent years; along with the growth year by year of electric railway freight volume; the traction transformer overload situation of each traction substation is day by day serious; having badly influenced the power supply quality of transformer, there is the phenomenon of the power supply capacity deficiencies such as the loss of voltage strengthens, utilance reduces, overload protection action frequency increases in each traction substation in succession.Although improve through many measures, the running overload situation of existing traction transformer continues always, have impact on normal train operation, over-zone feeding, the power failure equipments maintenance of traction substation full institute and railway security transport production etc.
The tractive power supply system of electric railway is the power source of electric locomotive, can be divided into by the kind of its supply current: DC system, low frequency single phase alternating current (A.C.) system and power frequency single phase alternating current (A.C.) system.Current China generally adopts power frequency single phase alternating current (A.C.) system.So-called traction transformer refers to the form of energy in order to electric energy being converted to needed for electric locomotive traction, by means of electromagnetic induction, converts the static electrical equipment of one of alternating voltage and electric current with identical frequency between two or more winding.Its load characteristic and conventional power transformer have very large difference, and main manifestations is: there are single-phase load load, rail return, high order harmonic component load etc.The delivery of electrical energy of three-phase electrical power system is given two respective load-carrying single-phase traction circuits by traction transformer, and two single-phase traction circuits give up-downgoing train power supply respectively.In the ideal case, two single-phase loads are identical, but in most of the cases, two phase load difference are very large, and according to statistics, single line electric railway traction no-load ratio accounts for 40%-50%, and load change is frequent, this must make three-phase power supply system disequilibrium and cause voltage fluctuation.
