(54) КОНТАКТНАЯ ПАРА(54) CONTACT PAIR

Изобретение огносигс к области электротехники , в частности к контактным устройствам, примен емым в высоковольтных выключател х на 35-22О кВ, огг ключающихс автоматически, а перезар жаемых вручную.The invention of ogosigs to the field of electrical engineering, in particular, to contact devices, used in high-voltage switches of 35–22 kV, is automatically switched on and recharged manually.

Известны контактные пары, состо щие из цилиндрических шгыр и гнезда . Необходимое контактное давление между элементами этих контактных пар создаетс за счет упругих деформаций рассечённого продольным пазом штыр , выполненного из соответствующего упругого материала. Недостаточна надежность известных контактных пар про вл етс в том, что не обеспечиваютс высокое контактное давление между контактирующими поверхност ми штыр и гнезда, возможность использовани дл изготовлени штыр неупругих материалов (меди , серебра, алюмини и т. п.), стабильное контактное давление, не завис щее от числа включений-отклк чеАий, стабильность контактного давлени при колебани х температуры окружающей средыContact pairs are known, consisting of cylindrical shgyr and sockets. The necessary contact pressure between the elements of these contact pairs is created due to the elastic deformations of the pin, made of a corresponding elastic material, cut by the longitudinal groove. The lack of reliability of the known contact pairs is manifested in the fact that high contact pressure between the contacting surfaces of the pin and the socket is not provided, the possibility of using nonelastic materials (copper, silver, aluminum, etc.) for the manufacture of the pin, stable contact pressure, not depending on the number of inclusions off, the stability of the contact pressure during fluctuations in ambient temperature

долговечность покрыти и многократность включений-отключений.the durability of the coating and the multiplicity of on-off.

Известна также контактна пара, соде держаща штырь в виде цилиндра со сквоз .ным продольным пазом, раздел ющим его на две половины, гнездо в виде полого цилиндра, фиксирующий и распорный элементы . Однако така контактна пара так се недостаточно надежна. Ivpo-Also known is a contact pair, soda holding a pin in the form of a cylinder with a through longitudinal groove dividing it into two halves, a nest in the form of a hollow cylinder, fixing and expansion elements. However, such a contact pair is also not reliable enough. Ivpo-

ме того, она имеет большие поперечные размеры, требует применени специальных материалов и сложна по конструкции .moreover, it has large transverse dimensions, requires the use of special materials and is complex in design.

Целью изобретени вл етс повыше-The aim of the invention is to increase

ние надежности контактной пары. Это достигаетс тем, что распорный элемент предлагаемой контактной пары выполненthe reliability of the contact pair. This is achieved by the fact that the spacer of the proposed contact pair is made

в виде резьбового штифта, расположенного в резьбовом отверстии, выполненномin the form of a threaded pin located in a threaded hole made

в одной из половин штыр внв зоны контактировани его с гнездом, при этом основание штифта расположен на другой половине штыр .In one of the halves, the pin of the internal contact zone is in contact with the socket, while the base of the pin is located on the other half of the pin.

На чертеже показана описываема The drawing shows the described

Claims

contact pair, longitudinal section. J62 Contact pair with tx; that is from pin 1, socket 2, lock 3 and spacer 4 elements. Pin 1 is a cylinder cut to a certain length by a through longitudinal groove dividing it into two or more halves. Nest 2 is made in the form of a hollow cylinder. The rivet element 3 serves as a rivet. A threaded pin is used as the spacer element 4. The pin 4 is screwed into a recess hole made in one of the floor (pin 1 so that it is outside the contact zone of the pin with the / socket 2, while the base of the pin is located on the other half of the pin. Assembly assembly The pairs are made as follows. Pin 1 is inserted inside slot 2, after which the position of the elements of the contact pair is fixed with a rivet 3. Then a threaded pin 4 is screwed into the threaded hole of the pin 1 up to the stop with a certain force into the opposite half of the pin. The accuracy of screwing in the pin 4 can be determined, for example, with a microhmmeter measuring the resistance of the contact pair, or with a special screwdriver with a thoriated value of the force of the pin twisting. TsIATII-203. The decoupling of the contact pair is ensured by using a shear fixing rivet 3, made, for example, of aluminum of the HELL mark. Claims of Invention The contact pair, comprising a pin in the form of a cylinder with a through longitudinal groove dividing it into two halves, a nest in the form of a hollow cylinder, fixing and expansion elements, so that, in order to increase reliability, the expansion element : filled in the form of a threaded pin located in a threaded hole made in one of the halves of the pin outside the zone of contact with the socket, while the base of the pin is located on the other half of the pin.
