Abstract
The utility model discloses a main and auxiliary integrated traction converter, which employs a main and auxiliary integrated design manner. A 4QC power module, an INV power module and an auxiliary conversion module are all integrated inside a traction converter cabinet, wherein an independent auxiliary converter cabinet is not required. Thus, the labor and material resources for designing the auxiliary converter can be saved, the space in a machine room of a locomotive is saved, and communication protocols can be optimized.
Description
Technical field
The utility model relates to a kind of current transformer, particularly a kind of major-minor one traction convertor.
Background technology
Along with the fast development of Chinese national economy, Urban traffic demand increases severely, and the track traffic technology is after development century-old on the experience, and is just fast-developing towards the direction of the integrated high output of height.Traction convertor is as the core component of electric locomotive, towards high-power, regulate control performance complete with to communicate by letter, the glitch-free future development of electrical network, this degree of integration to traction convertor is had higher requirement undoubtedly.
Yet present domestic main flow high-power electric Locomotive Converter all adopts the design of Separation of main work and non-main work formula, just couples together by cable when locomotive is always assembled, and passes through independently bus and communication of locomotive.Increased so extraly many manpower and materials costs, also can cause between locomotive machinery transition to crowd, wasted the space, potential safety hazard also increases synchronously.
Summary of the invention
Technical problem to be solved in the utility model is for the prior art deficiency, to provide a kind of major-minor one traction convertor, human cost and material procurement cost when reducing design with test; When locomotive is always assembled, reach joint space-efficient purpose, more be conducive to the layout between machinery; While optimize communicate agreement.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of major-minor one traction convertor, comprise cabinet, described cabinet middle part is provided with two vertical beams, be provided with two dividing plates in the middle chamber between two vertical beams, described two dividing plates are divided into three cavitys with middle chamber, comprise that the cavity of motion control unit is equipped with at the top, the cavity of heat exchanger and the cavity that the bottom is fixed with input and output terminal are equipped with in the middle part; Middle chamber left side cabinet is provided with three cavitys from top to bottom altogether near a side of middle chamber, and wherein the cavity at top is used for placing the 4QC power model, and the cavity at middle part is used for placing the INV power model, is fixed with contactor in the cavity of bottom; Middle chamber left side cabinet is provided with two cavitys altogether away from a side of middle chamber, comprise the cavity that is fixed with copped wave resistance that is positioned at part and be positioned at lower part be used for place the cavity of auxiliary change module, wherein be positioned on the cabinet at auxiliary change module rear of cavity of lower part and be fixed with reactor; Be provided with five cavitys in the cabinet on described middle chamber right side, comprising four cavitys that are positioned at upper part be positioned at a cavity that is fixed with discharge resistance and input and output terminal of lower part; In four cavitys of upper part, be used for placing the 4QC power model near two cavitys of middle chamber, be used for placing the INV power model away from two cavitys of middle chamber.
As preferred version, all be connected by low-inductance bus between described 4QC power model and INV power model, the auxiliary change module.
Be fixed with capacitor on the cabinet at described input and output terminal rear.
Compared with prior art, the beneficial effect that the utility model has is: the utility model adopts major-minor integral structure to save auxiliary converter cabinet, for having saved the space between locomotive machinery, more is conducive to the layout between machinery; When always assembling, locomotive can reach joint space-efficient purpose, and simultaneously can also the optimize communicate agreement; In addition, the utility model has realized that the energy between asymmetric converter module is uniform.

Embodiment
As depicted in figs. 1 and 2, the utility model one embodiment comprises cabinet, described cabinet middle part is provided with two vertical beams 10, be provided with two dividing plates 11 in the middle chamber between two vertical beams 10, described two dividing plates 11 are divided into three cavitys with middle chamber, comprise that the cavity of motion control unit 5 is equipped with at the top, the cavity of heat exchanger 6 and the cavity that the bottom is fixed with input and output terminal 8 are equipped with in the middle part; Middle chamber left side cabinet is provided with three cavitys from top to bottom altogether near a side of middle chamber, and wherein the cavity at top is used for placing 4QC power model 1, and the cavity at middle part is used for placing INV power model 2, is fixed with contactor 7 in the cavity of bottom; Middle chamber left side cabinet is provided with two cavitys altogether away from a side of middle chamber, comprise the cavity that is fixed with copped wave resistance 4 that is positioned at part and be positioned at lower part be used for place the cavity of auxiliary change module 3, wherein be positioned on the cabinet at auxiliary change module 3 rears of cavity of lower part and be fixed with reactor 12; Be provided with five cavitys in the cabinet on described middle chamber right side, comprising four cavitys that are positioned at upper part be positioned at a cavity that is fixed with discharge resistance 9 and input and output terminal 8 of lower part; In four cavitys of upper part, be used for placing 4QC power model 1 near two cavitys of middle chamber, be used for placing INV power model 2 away from two cavitys of middle chamber.Because space and structural limitations, the utility model traction convertor is asymmetric layout.Rule of thumb, the structure of the asymmetric layout of converter module will inevitably cause the energy of traction convertor not uniform, the load that will cause some or several modules to bear is more than other module, electric current on these modules also will be larger than the electric current on other modules, and its loss is also just corresponding large; When this imbalance distributes the limit that reaches certain, the excessive situation of local power consumption will occur, accelerate the aging of converter module and device thereof, cable, and then will shorten its useful life; When power consumption during greater than the rated value of converter module and device thereof, will reduce its reliability, even the fault that can not estimate occurs.Therefore all be connected by low-inductance bus 14 between 4QC power model 1 of the present utility model and INV power model 2, the auxiliary change module 3, saved absorbing circuit, make circuit more succinct reliable, reduced like this pyrotoxin of cabinet inside, effectively suppressed the rising of cabinet internal temperature, and the electromagnetic interference between the components and parts.The turnover cable of low-inductance bus to the distance of modules about equally, namely getting from modules can be about equally, and then realizes the load balancing of modules, is that the energy between the traction convertor modules is evenly distributed.Reactor 12 is used for the stray inductance of absorbing circuit, and then realizes that the energy of whole traction convertor is uniform.
