Description

Изобретение относитс к электротехнике , в частности к производству изол торов, и может быть использовано при изготовлении электроаппаратуры электрических печей,The invention relates to electrical engineering, in particular, to the manufacture of insulators, and can be used in the manufacture of electrical equipment for electric furnaces,

Цель изобретени - повышение надежности .The purpose of the invention is to increase reliability.

На чертеже изображен опорный изол тор, разрез.The drawing shows the support insulator, section.

Опорный изол тор имеет металличес кую арматуру 1, изготовленную в виде двух одинаковых деталей, зеркально расположенных относительно горизонтальной оси в верхней и нижней части изол тора, корпус 2, выполненный из армированного стекла волокном пластика и напрессованный на стержень 3, выполненный из изол ционного материала .The support insulator has a metallic reinforcement 1, made in the form of two identical parts, mirrored about the horizontal axis in the upper and lower parts of the insulator, case 2, made of glass fiber reinforced plastic and pressed onto the rod 3, made of insulating material.

Металлическа арматура выполнена в виде ступенчатого цилиндра со сквозным отверстием 4. Торцы стержн 3 закреплены в цилиндрах на участке меньшей ступени. Большие ступени цилиндров расположены у торцов корпуса .The metal fittings are made in the form of a stepped cylinder with a through hole 4. The ends of the rod 3 are fixed in the cylinders in the area of the lower stage. Large cylinder steps are located at the ends of the body.

Дл повышени прочности соединени на поверхности втулок могут быть выполнены кольцевидные выемки. Стержень 3 может быть выполнен из стеклопластика , высоковольтного фарфора, корунда и др.To increase the strength of the joint, annular recesses can be made on the surface of the sleeves. The rod 3 can be made of fiberglass, high-voltage porcelain, corundum, etc.

После выдержки 10 мин изол тор извлекаетс и помещаетс в термошкаф дл нормализации .a metal mold is loaded with a sample of a press material heated to 80-90, after which the mold is closed and the specific pressure rises to 250 kgf / cm at a temperature of 150 + 5 ° C. After holding for 10 minutes, the isolator is removed and placed in a heating cabinet for normalization.

В описанной конструкции рабочие части изол тора (торцы) почти полностью защищены металлической арматурой , что предохран ет тело изол тора от повреждений при монтаже и транспортировке, а также от виброударного воздействи шины. При по влении усили изгиба тело изол тора испытывает сжатие между широкими част ми втулки.In the described construction, the working parts of the insulator (ends) are almost completely protected by metal reinforcement, which protects the insulator body from damage during installation and transportation, as well as from vibro-impact tires. When a bending force is created, the insulator body experiences compression between the wide parts of the sleeve.

Claims

The invention relates to electrical engineering, in particular, to the production of insulators, and can be used in the manufacture of electrical equipment for electric furnaces. The purpose of the invention is to increase reliability. The drawing shows the support insulator, section. The support insulator has a metal reinforcement 1, made in the form of two identical parts, mirror-image relative to the horizontal axis in the upper and lower parts of the insulator, body 2, made of glass fiber-reinforced plastic and pressed onto the rod 3 made of insulating material. The metal fittings are made in the form of a stepped cylinder with a through hole 4. The ends of the rod 3 are fixed in the cylinders in the area of the lower stage. Large cylinder steps are located at the ends of the body. To increase the strength of the joint, annular recesses can be made on the surface of the sleeves. The rod 3 may be made of glass plastic, high-voltage porcelain, corundum, etc. Example. The insulator armature is placed in a mold that heats up to 150 ° C. After the metal mold is heated, a weight of the press material heated to 8090 is loaded into it, after which the mold is closed and the specific pressure rises to 150 + 5 ° C. kgf / cm After holding for 10 minutes, the isolator is removed and placed in a heating cabinet for normalization. In the described construction, the working parts of the insulator (ends) are almost completely protected by metal reinforcement, which protects the insulator body from damage during installation and transportation, as well as from vibro-impact tires. When a bending force is created, the insulator body experiences compression between the wide parts of the sleeve.
