Description
Дл предотвращени кратковременных размыканий контактов электрических выключателей под действием электродинамических сил, возникших при замыкании этих контактов под нагрузкой, примен ют устройства , выполненные в виде магнитной системы, корь которой закреплен на держателе подвижных контактов.To prevent short-term opening of the contacts of electrical switches under the action of electrodynamic forces arising from the closure of these contacts under load, devices made in the form of a magnetic system, the measles of which is fixed to the holder of moving contacts, are used.
Предлагаемое устройство более совершенно по сравнению с известными , так как работа его не зависит от величины нагрузки. Это достигаетс благодар выполнению пол ризованного неподвижного элемента магнитной системы в виде посто нного магнита.The proposed device is more perfect in comparison with the known ones, since its operation does not depend on the magnitude of the load. This is achieved by making the polarized stationary element of the magnetic system in the form of a permanent magnet.
На чертеже изображена схема предлагаемого устройства.The drawing shows a diagram of the proposed device.
Устройство выполнено в виде посто нного магнита 1, укрепленного на неподвижном контакте 2, и кор 3, св занного с подвижным контактом 4. Посто нный магнит 1 представл ет собой пол ризованный элемент магнитной системв, который предотвращает вибрацию контактов под действием элeктpoдинa гичecкиx сил при любом токе, проход шем через контакты.The device is made in the form of a permanent magnet 1 fixed on a fixed contact 2, and a core 3 connected to a moving contact 4. The permanent magnet 1 is a polarized element of the magnetic system, which prevents the vibrations of the contacts under the action of electromagnetic forces at any current, passage shem through the contacts.
Наиболее целесообразно выполн ть магнит из железо-никель-алюминиевых сплавов.It is most advisable to make a magnet from iron-nickel-aluminum alloys.
Предмет изобретени Subject invention
Устройство дл предотвращени кратковременных размыканий контактов электрических выключателей под действием электродгпшмических сил, возникших при замыкании этих контактов под нагрузкой, выполненное в виде магнитной системы, корь которой закреплен на держателе подвижных контактов, отличающеес тем, что, с целью устранени вли ни нагрузки на работу устройства, пол ризованный неподвижный элемент магнитной системы выпо,тнен в виде посто нного магнита.A device for preventing short-term opening of contacts of electrical switches under the action of electro-magnetic forces arising from the closure of these contacts under load, made in the form of a magnetic system, the measles of which is fixed to the holder of movable contacts, characterized in that The polarized stationary element of the magnetic system is emitted in the form of a permanent magnet.
