Description
Technical Field
The invention relates to the technical field of breaker electromagnetic operating mechanisms, in particular to a full-automatic optimization design method of a breaker electromagnetic operating mechanism based on Matlab and Maxwell.
Background
In recent years, with the large-scale access of distributed power supplies and energy storage devices, the rapid development of power electronic technology, and the increase of electric loads, the quick-break capability of the circuit breaker is receiving more and more attention. Particularly, direct current systems such as large ship power supply systems, photovoltaic direct current micro-grid systems, urban rail transit power supply systems and the like are developed greatly in certain specific occasions. With the continuous increase of the capacity of the power system and the continuous improvement of the voltage level, the indexes of the short-circuit current peak value and the on-off time of the circuit breaker are also continuously improved. Although the traditional spring type mechanical circuit breaker has the advantages of strong loading capacity and stable conduction, the response speed is slow, generally about tens of milliseconds, and the requirement of a quick on-off action occasion in a power system cannot be met; the power electronic switch has high response speed, but has overlarge on-state loss and low voltage endurance capability. Therefore, designing a quick-acting economic and environment-friendly circuit breaker meeting the requirements of the current power system is the key for constructing the future power system and protecting the safe and stable operation of the future power system.
At present, most of quick-break circuit breakers use electromagnetic mechanisms, and the design steps of the mechanisms and driving circuits are complicated. Firstly, a designer needs to manually calculate parameters of an operating mechanism, then a Maxwell simulation model is established, the output and motion characteristics of the electromagnetic mechanism are obtained through the simulation model, and if the simulation result does not meet the design requirement, the model parameters are continuously corrected until the simulation result meets the design requirement. The prior art has the following disadvantages: 1) the method of continuously and manually changing the model parameters is adopted to obtain the design meeting the requirements, and the design has low flexibility, consumes time and labor. 2) The variable parameters of the electromagnetic operating mechanism are multiple, so that the actual circuit breaker operating mechanism designed finally by a designer is not optimally designed. 3) The electromagnetic simulation analysis of the complete electromagnetic operating mechanism is established in electromagnetic analysis simulation software based on finite elements such as Maxwell, the calculation load is heavy, the change rule of the set simulation parameters is rigid, and a designer can design the operating mechanism meeting the requirements of the circuit breaker by combining years of design experience. The design process of the electromagnetic operating mechanism of the circuit breaker is not beneficial to the rapid forming and optimization of circuit breaker products, and the development and the use of the circuit breaker are seriously influenced.
