Abstract

Single-pole sealed DC contactors are produced by many foreign electrical engineering companies, and there are no modern analogues of Russian production. One of the problems when creating such contactors is the design of the magnetic system, which is the subject of the article.

The purpose of the study is to identify the optimal magnetomotive and electromagnetic forces of an armored electromagnet with a hollow core.

Materials and methods. The studies were carried out on the basis of the magnetic system of the EV200 contactor from Kilovac, taking into account possible refinements of its geometric parameters. The calculation of the electromagnetic force was carried out by numerical simulation by the finite element method in Comsol Multiphysics.

Research results. The design features of the magnetic system used in contactors from Gigavac and Kilovac are described. Calculation studies of the electromagnetic force were carried out for various ratios of the geometric parameters of the armature-core assembly, which characterize the distinctive features of the magnetic system. The dependences of the electromagnetic force on the design parameters of an armored electromagnet with a hollow core were obtained. Based on the results of the distribution of magnetic induction, an assessment of the correctness of the choice of parameters of the magnetic system was made.

Conclusions. The proposed approaches to calculating electromagnetic and magnetomotive forces are verified by comparing the calculation results with the data of an industrial design and can be used in the development of contactors manufactured in Russia.
