Embodiment
For making the object of the invention, technical scheme and advantage clearer, clear and definite, below develop simultaneously embodiment to further explain of the present invention with reference to accompanying drawing.
Referring to Fig. 1; The outer relatively cooling of internal cooling system system is the system of a more complicated; The thyristor converter valve is indoor suspension type quadruple valve tower structure in this project; Therefore in each quadruple valve tower unit four valves are arranged, each quadruple valve tower by about, about 6 layers totally 12 thyristor modules form.Each valve is made up of three thyristor modules, and each thyristor module is made up of two valve layers.Each valve layer is parallelly connected with the RC loop respectively by 13 thyristor levels; Be composed in series with 4 an electricity anti-device again.
Thyristor, damping resistance and valve reactor cool off with deionized water.Each valve tower has 2 inlet channels and 2 outlet conduits to the valve tower recirculated cooling water to be provided through top, the valve Room.
Whole valve tower structure is complete symmetric pattern, and water cooling system also is like this.Therefore, the single thyristor module in each quadruple valve tower is studied, promptly so neither lost accuracy, again simplified model greatly.
According to actual conditions; Single thyristor module comprises two valve layers; 13 thyristors of each valve layer are connected by 14 square Aluminium Radiator institute's double teams and with damping resistance, and to reach the purpose of heat radiation, the heat of radiator is then taken away through the cooling water that flows through its inner U type water channel.To single quadruple valve, cooling circuit arranges that from top to bottom the water route in single component is arranged as shown in Figure 2.
In conjunction with the actual size size, utilize Gambit software to make up the single component model, obtained basic physical model figure like this, to its setting of carrying out relevant parameter, use the Fluent software emulation then, obtain the simulation result figure under the different transmission line capabilities.
It is as follows to draw the tables of data that needs through various simulation result figure at last:
Key point of the present invention is accurately obtaining of original CONSTRUCTINT PHYSICAL MODELS and actual parameter.
The present invention is actual through theory and combining, on the basis of practical application, makes up physical model accurately; And, obtain comparatively real simulation result, thereby the real result under the prediction different situations with the creation data position foundation of reality; For actual production provides reference frame, instruct production application.
Should be understood that application of the present invention is not limited to above-mentioned giving an example, concerning those of ordinary skills, can improve or conversion that all these improvement and conversion all should belong to the protection range of accompanying claims of the present invention according to above-mentioned explanation.
