Устройства выводов из коммутационных шкафсе КРУН предназначены дл лрисоеди- нени отход щих линий электропередач, обычно воздушных, и дл ввода в КРУН энергии от понижающего силового трансформатор ра. Эти устройства могут быть выполнены кабельными или воздушными,The terminals of the switchgear of the switchgear of the metal-clad switchgear are designed for locating the outgoing power lines, usually overhead, and for inputting the energy from the step-down power transformer to the switchgear. These devices can be made cable or air,

Воадушг ые выводы дл присоединени воздущных линий более экономичны и конструктивно проще. Они выполнены в виде Грех- фазной группы проходных изол торов, узтановч ленных на крыше шкафа КРУН, и смонтиро« . ванного над ними также на крыше шкафа 2 небольшого портала с трехфазной грутшой опорньи. изол торе.Air inlets for connecting air lines are more economical and structurally simpler. They are made in the form of the Sin-phase group of bushing insulators located on the roof of the KRUN cabinet and mounted ”. above them is also on the roof of the closet 2 of a small portal with a three-phase gruntshop support. isolate torus

Однако угол выхода линий ограничен, так как выходной шлейф ориентирован практичеоки в направлении,.-перпендикул рном прот жен:-ности р да ипсафов КРУН, и может измен ть- с в ограниченном угловом диапазоне.However, the exit angle of the lines is limited, since the output stub is practically oriented in a direction that is perpendicular to: - of the range of idlers KRUN, and can vary with a limited angular range.

Применение современных коммутационных аппаратов, новых видов электрической изол ции позвол ет в р де случаев резко-уменьшить габариты чеек КРУН, В этих условийх применение устройств воздушных выводов известных конструкций напри ем лемо-из- а крайней ограниченности места дл их размещени и невозможности обеспечить регламв тированные воздушные зазоры между высо-« ковольтными Трковедушими част ми.The use of modern switching devices, new types of electrical insulation makes it possible in a number of cases to drastically reduce the size of the KRUN cell. In these conditions, the use of air terminal devices of known structures, such as the extreme limitation of space for their placement and the inability to provide air gaps between high-voltage Tropeled parts.

Целью изобретени вл етс устранение этих недостатков в конструкции КРУН .ц. воз- душными выводами, т.е.; получение такой конструкции воздущных выводов, котора сг|о- собствовала бы уменьшению габаритов КРУН и обеспечивала выход линии BI широком диапв зоне углов.The aim of the invention is to eliminate these disadvantages in the design of the KRUN .c. air conclusions, i .e .; obtaining such a design of air leads, which would reduce the size of the KRUN and ensure the output of the BI line in a wide range of angles.

Claims

The goal is achieved due to the fact that in the proposed device the pass-. The air duct insulators are placed once in a vertically installed hollow column vertically mounted on the cabinet roof in horizontal planes arranged one above the other and connected to electrical equipment of the scale-pack with insulated tires placed inside the core. Each horizontal plane is copied three insulators can be placed. In addition, in order to change the direction of the exit line in each horizontal plane, the following four insulators are marked: -. ra, whose axes are mutually perpendicular. 10 On flash 1 shows a schematic small-sized KRUN with a Pszdgöe column installed on it; in fig. 2 "a cross section of the ends of the leads with the output of the line directly from the pass-through isolator; in fig. 3 and FIG. 4 - options for changing the line output direction using the ". travel isolator Small-sized KRUN 1 carries a hollow core, 2, with three-phase groups of 20 insulators through passage 3 and bypass insulators 4.; Packages are insulated inside the column; busbars 5, connecting the bushing with the switchgear of the switchgear switchgear.
