Изобретение относитс к электротехнике и может быть Использовано в качестве переключател мощности, например в инверторах.The invention relates to electrical engineering and can be used as a power switch, for example, in inverters.
Известны электроконтактные устройства-переключатели мощности коллекторного типа, содержащие коллектор и коммутирующие щетки fl.Known electrocontact devices-switches of power of the collector type, containing a collector and switching brushes fl.
Недостатком известных устройств вл етс то, что между щетками и коллекто- ,д ром имеетс скольз щий контакт, что сильно ограничивает величину тока вследствие неизбежного искрообразовани .A disadvantage of the known devices is that there is a sliding contact between the brushes and the collector, which greatly limits the amount of current due to the inevitable sparking.
Известно электроконтактное устройство, в котором соприкасающиес поверхности выход т из контакта и вход т в контакт одновременно по всей линии контакта без скольжени . Устройство содержит два зубчатых колеса, наход шихс в непрерывном зацеплении, профиль 20 зубьев колес очерчен по центроидам .An electrocontact device is known in which the contacting surfaces exit the contact and come into contact simultaneously over the entire contact line without sliding. The device contains two gears, which were in continuous engagement, the profile of 20 teeth of the wheels is outlined along centroids.
Однако его нельз применить дл периодического замыкани и размыкани элек-р / трических цепей, так как зубчатые колеса пребывают в непрерывном зацеплении, то есть вмеханическом и электрическом контакте, и при этом каждое из колес выполнено из одного материала.However, it cannot be used for periodically closing and opening electric / tric-chains, since the gears are in continuous engagement, that is, mechanical and electrical contact, and each of the wheels is made of the same material.
Целью изобретени 51вп етс обеспечение периодического замыкани и размыкани электрической цепи с уменьшением искрообразовани .The purpose of the invention is to provide periodic closure and opening of the electrical circuit with reduced sparking.
Цель достигаетс тем, что в извест-ном электроконтактном устройстве, со- : сто щем из двух наход щихс в непрерывном зацеплении зубчатых контакти- рукацих колес, профиль зубьев которых очерчен по центроидам, на одном из колес часть зубьев изготовлена электроизолированными , а остальные - электропровод щими , при этом электропровод щие зубь электрически соединены.The goal is achieved by the fact that in a known electrocontact device, consisting of two permanently engaged gear contact wheels, the tooth profile of which is outlined along centroids, on one of the wheels some of the teeth are made electrically insulated The electrically conducting teeth are electrically connected.
На чертеже схематически показано электроконтактное устройство.The drawing shows schematically the electrical contact device.
Электропровод щее колесо 1 находит с в контакте с электропровод щими зубь ми 2 колеса 3, друга часть зубьевThe electrically conductive wheel 1 is in contact with the electrically conductive teeth 2 of the wheel 3, another part of the teeth
