Abstract

FIELD: electrical engineering, high voltage electrical actuators manufacturing. SUBSTANCE: device has base plate 1 with two insulating bushings 2 fitted on it, two groups of upper and lower contact breaking actuators 3 and 4, device 5 for automatic and hand-by operating, flap-chuck 6 working like arc blowing-out element and blade, simultaneously. S-shaped bracket 7 is fitted at flap-chuck 6 upper end, it works like operation rod for circuit connection and disconnection operating. EFFECT: higher speed of circuit contacts breaking and better operation capability for both working regimes of circuit protection and disconnection.

Изобретение относится к высоковольтному аппаратостроению и касается конструкции предохранителей-разъединителей, совмещающих в себе дополнительно функцию разъединителя. Предохранитель-разъединитель содержит основание 1, на котором закреплены два изолятора 2 с верхней 3 и нижней 4 системами размыкаемых контактов, механизм 5 автоматического и ручного откидывания, патрон 6, служащий одновременно дугогасительной камерой и ножом разъединителя. На верхнем конце патрона 6 закреплен кронштейн 7 S-образной формы, служащий для взаимодействия с оперативной штангой при производстве операций отключения и включения в режиме разъединителя. Благодаря S-образной конструкции кронштейна стало возможным получить повышенную скорость размыкания контактов и тем самым повысить отключающую способность при работе предохранителя-разъединителя в режиме разъединителя.

The invention relates to high-voltage apparatus and relates to the design of fuses-disconnectors, combining in themselves the additional function of the disconnector. The fuse-disconnector contains a base 1, on which two insulators 2 are fixed with the upper 3 and lower 4 openable contact systems, an automatic and manual tilt mechanism 5, a cartridge 6, which serves both as an arcing chamber and a disconnector knife. At the upper end of the cartridge 6, an S-shaped bracket 7 is fixed, which serves to interact with the operational rod during disconnecting and switching operations in the disconnector mode. Thanks to the S-shaped design of the bracket, it became possible to obtain an increased contact opening speed and thereby increase the breaking capacity during operation of the fuse-disconnector in the disconnector mode.
