Intelligent contactor virtual prototype designing platform

Abstract

The invention relates to an intelligent contactor virtual prototype designing platform. The intelligent contactor virtual prototype designing platform comprises a type selection module, a parameter setting module, a calculating module and an analyzing module. The model selection module provide s host computer interface, and is used for the user to select the main circuit type, the control circuit type, the electromagnetic system type, the contact system type and the material type as needed; the parameter setting module sets parameters of the selected types after the type selection is determined; the calculating module comprises an electromagnetic field calculating model which includes three parts of an electromagnetic system dynamic model, a contact electrodynamic force calculating model and a circuit device electromagnetic model, and obtains dynamic characteristics of the absorption, holding and breaking whole process of the electromagnetic system under different control schemes, and obtains the electromagnetic field distribution parameter of the contact system when the contact system is loaded with different main circuits and the electromagnetic property parameters of the circuit and the device through the electromagnetic field calculating model; and the analyzing module analyzes the parameters obtained by the calculating module. The intelligent contactor virtual prototype designing platform comprehensively takes multi-field coupling of electricity, magnetism, heat, machinery and fluid into account.

Description

technical field [0001] The invention relates to a virtual prototype design platform for an intelligent contactor. Background technique [0002] The contactor is one of the most widely used control appliances as a control appliance that is frequently switched on and off. With the rapid development of the power industry, construction and equipment manufacturing industries, higher and higher requirements are placed on the reliability and continuity of power supply and control systems, which promotes the replacement of contactors. Contactors are moving towards small size, high Reliability, long battery life, low noise, intelligence, energy saving and environmental protection. Facing the market demand for high-performance contactors, how to ensure product performance while shortening the new product development cycle and cost, and developing personalized, distinctive contactors with independent intellectual property rights has become the focus of attention of enterprises.

Problems solved by technology

[0003] The working process of the contactor involves many physical fields such as electricity, magnetism, heat, machinery and flow field, and each physical field is in a transient nonlinear change, which makes the operation of the contactor more complicated.

Traditional design methods are often designed from a static single-field perspective combined with engineering experience. The design results are difficult to meet the design expectations. After continuous experimental testing and improvement, they can reach the standard and enter the mass production process, which eventually leads to a long cycle of product development. and high cost, unable to meet the design requirements of high quality and low cost
