Description
Technical field
The utility model relates to track traffic traction convertor power checking system, specifically is a kind of friendship orthogonal traction convertor pure inductance bearing power checking system.
Background technology
Hand over orthogonal (DC/AC) traction convertor on locomotive and motor-car, to use comparatively extensive at present; What adopt when handing over the examination of orthogonal traction convertor power is the method (see figure 1) of resistance coilloading as load; There is following weak point in this method: because when handing at present orthogonal traction convertor power certification test, load wherein has resistance, certainly exist more electric energy and transform for thermal loss; Both increase experimentation cost, wasted the national energy again; Powerful relatively experiment power supply need be provided, need buying high-power resistance load system, increase the cost that equipment drops into.
Existing friendship orthogonal traction convertor power checking system exists following not enough:
One of which, in the time of handing over the examination of orthogonal traction convertor power, three pole reactor load and single-phase inductance load consumption be reactive power, and three-phase resistance load and single-phase resistance load consumption is active power.All energy consumptions can simply be divided into three parts among Fig. 1: the own loss power of traction convertor (very little); Inductive load heating loss power (very little); The power (very big) that ohmic load consumes.The power that ohmic load consumes is very big, thus so directly cause waste of electric energy, not energy-conservation, low-carbon (LC) not.
Its two, powerful direct supply is relatively expensive, and is uneconomical.
Its three, powerful three-phase resistance loads value is high, uneconomical.
The utility model content
The utility model technical matters to be solved is, and is not enough to prior art, and a kind of friendship orthogonal traction convertor pure inductance bearing power checking system is provided, and energy savings reduces cost, and realizes the low-carbon (LC) demand.
For solving the problems of the technologies described above; The technical scheme that the utility model adopted is: a kind of friendship orthogonal traction convertor pure inductance bearing power checking system; Comprise the friendship orthogonal traction convertor, three pole reactor load, single-phase inductive load, computing machine, first measuring system and second measuring system that are connected with direct supply; Computing machine is connected with handing over orthogonal traction convertor, first measuring system, second measuring system respectively; The parallel connection of first measuring system inserts between the single-phase output terminal of single-phase inductive load and friendship orthogonal traction convertor; The parallel connection of second measuring system inserts between the three-phase output end and three pole reactor load of handing over the orthogonal traction convertor; The three pole reactor load connects into star-like, and the three pole reactor load is connected with the three-phase output end of handing over the orthogonal traction convertor, and single-phase inductive load is connected with the single-phase output terminal of handing over the orthogonal traction convertor.
Said three pole reactor load is high-power three pole reactor load.
Said single-phase inductive load is high-power single-phase inductive load.
Said friendship orthogonal traction convertor is a kind of in TGA9, the TGA9C traction convertor.
The utility model adopts the load of pure inductance as the power examination, does not consume active power, energy-conservation, low-carbon (LC); Do not need the ohmic load in the examination of conventional power,, reduced cost, practiced thrift the space in the factory building simultaneously for enterprise has reduced the input of capital assets; Do not need too powerful direct supply, reduced production cost; Guaranteeing under the electric current examination requirement that product is equal to; Realized handing over the pure inductance bearing power examination of orthogonal traction convertor; Three-phase resistance load and single-phase ohmic load in the power examination have been cancelled; It is original 1/7 that the output power of direct supply is reduced to approximately, and when follow-up test board was built, direct supply power reduced significantly.
