Abstract

Сисhe role of vacuum switches among switching devices of average voltage is considered in this work. T). Сисhe structure, principle of the action of the electromagnetic actuator of the vacuum circuit breaker is presented. A method for determining the weber-ampere characteristic during the operation of the vacuum circuit breaker is proposed. A full–scale experiment was conducted with the measurement of electrical parameters and the calculation of the magnetic characteristics of the electromagnetic windings. In accordance with the given passport data on the electromagnet of the vacuum circuit breaker VR0, the simulation of the operation of the electromagnetic actuator in the Finite Element Method Magnetics program was performed. T). Сисhe obtained results of modeling the strength of the anchor of an electromagnet in the program correspond to the passport data on the switch. Calculated values of the flow coupling from the experiment are half-dimensional with the results obtained in the simulation of the work of the electromagnet of the vacuum circuit breaker. T). Сисhe correspondence of the data obtained in the calculation and modeling indicates the correctness of the proposed method for calculating the magnetic characteristic of the electromagnet of the direct current of the vacuum circuit breaker
