Research On Modeling And Simulation Of Vacuum Breaker Operation Mechanism

With the fast development in the electric power systems, it is put forward the higher request to the quality and function of breaker which is one of the main control components in transmission and distribution systems. It is the initial topic of switch profession to put the development of the good and dependable breaker quickly.The virtual kind machine technique in the mechanical engineering which is also called machine system dynamic simulation technique is quickly developed with the fast development of computer technique on 90's in 20 centuries. First the kind machine model is established on computer, and various dynamic state functions are analyses, then the design project of the kind machine is improved, thus the traditional real object material machine is replaced by the digital form. Make use of the virtual kind machine technique, can consumedly simplify the design development process of the machine product, significant shorten the product development period, a great deal of development expenses of decrease product and cost, clearly raise the product quality, raise the system function of the product and acquire superior turn with the creative design product. Therefore, once that technique appear, it is immediately biggest valued by the flourishing nation, relevant research organization, university and company of the industry, many manufacturers in succession leads the virtual kind machine technique into each from of the product develops to win, obtaining the good economic performance.This thesis build up the vacuum breaker's holding to move according to many body system dynamics theories the organization kinetics and the mathematics model of the dynamics combine the applied ADAMS(Automatic Dynamic Analysis of Mechanical System) machine system of the automatic dynamics analyzes the software to construct the vacuum breaker spring to hold the virtual model of move the organization, carrying on dynamic state's imitate to the model really, acquiring the vacuum breaker to move the sport characteristic of moving contact, some parameters of moving contact a speed to carry on dynamic state's imitate to the influence true and excellent turn. Through the work enunciation that the applied ADAMS software, it can expediently build up the entity model that the parameter turn, and adopts to have another just the body system dynamics principle to carry on imitating the true calculation. It uses to hand over with each other the type sketch environment and parts database and controls the database, the dint database, using to pile up the wood method to build up the 3D machine system parameter to turn the model, also pass as to it's exercise the function imitates really, analyzes, comparison to study the emulation kind machine, the design project that thus provide the eligibility to choose. The ADAM analytical software sets up the true accuracy of the mimicry high with credibility good.For the design of the breaker product, virtual kind machine technique can effectively shorten the product development period and the exaltation product quality, having the actual meaning of the certain engineering.
