Description

Известен разъединитель дл высокого и сверхвысокого напр жени с нодвижным контактом, укрепленным на вис щем изол торе, например гирл нде, и .перемещаемым при помощи троса.A disconnector for high and ultra-high voltage is known with a fixed contact fixed on a hanging insulator, for example a wire, and moved by means of a cable.

Подобные разъединители требуют наличи значительного количества изол торов, недостаточно надежны и имеют высокую сгоимость.Such disconnectors require a large number of insulators, they are not reliable enough and have a high compatibility.

В описываемом разъединителе указанные недостатки устранены тем, что его нож и губка закреплены непосредственно на проводах линии передачи или на шинах распределительного устройства.In the described disconnector, these disadvantages are eliminated by the fact that his knife and sponge are fixed directly on the wires of the transmission line or on the busbars of the switchgear.

На фиг. 1, 2 и 3 изображен эскиз предлагаемого разъединител в ipex вариантах.FIG. 1, 2 and 3 shows a sketch of the proposed disconnector in ipex variants.

Нож / и губка 2 разъединител закреплены непосредственно на проводах 3 линии передачи или на щинах распределительного устройства (фиг. 1).The knife / and the sponge 2 of the disconnector are fastened directly to the wires of the 3 transmission line or to the switchgear (Fig. 1).

Нож 1 разъединител может быть выполнен в виде груза, имеющего форму, например, цилиндра, шара, конуса или другого тела обтекаемой формы, а губка 2 разъединител - в виде обруча, корзины, круглой сетки и т. п. При этом дл безотказного попадани ножа в губку отношение их линейных поперечных размеров выбираетс не менее 1 : 8.The knife 1 of the disconnector can be made in the form of a load having the form of, for example, a cylinder, a ball, a cone or another body of a streamlined shape, and the sponge 2 of the disconnector can be in the form of a hoop, a basket, a round mesh, etc. the ratio of their linear transverse dimensions to the sponge is not less than 1: 8.

Блок 4, привод щий в движение нож разъединител , укрепл етс на проводе 3 или же на шине распределительного устройства; при этом между блоком и лебедкой 5 устанавливаютс изол торы 6. При подобной конструкции разъединител устран етс провес соединительного провода между губкой и местом его креплени . Установка губки 2 производитс на консоле 7.The block 4, the moving knife of the disconnector, is fixed on the wire 3 or on the switchgear bus; In this case, insulators 6 are installed between the unit and the winch 5. With such a design of the disconnector, the sag of the connecting wire between the sponge and its attachment point is eliminated. The installation of the sponge 2 is carried out on the console 7.

Нож разъединител может быть выполнен в виде стержн , двил ущегос поступательно по радиусу или иным образом до попадани в губку. Губка в этом случае может представл ть собой провод, трубу или стержень, расположенные под углом от 10 до 90° к ножу (фиг. 2).The knife of the disconnector can be made in the form of a rod, the dvil can be propelled progressively along the radius, or otherwise before entering the sponge. In this case, the sponge can be a wire, a pipe or a rod angled from 10 to 90 ° to the knife (Fig. 2).

Губка 2 может устанавливатьс или на консоле 7 серповидной формы, укрепленной на проводе линии передачи, или шинах, или жеThe sponge 2 can be mounted either on a crescent shaped cantilever 7 mounted on the transmission line wire or tires, or

может быть образована гибкой расщепленной отт жкой 8 (фиг. 3). В этом случае отт жка 8 в месте пересечени ее с ножом I/ разъединител расщепл етс на два провода, которые вместе с пружиной 9 образуют контактный треугольник, куда входит нож разъединител .It can be formed by flexible split wire 8 (Fig. 3). In this case, the delay 8 at the point of its intersection with the knife I / disconnector splits into two wires, which together with the spring 9 form a contact triangle, which includes the disconnector knife.

При необходимости включить или отключить разъединитель приводна лебедка 5 приводитс во вращение и перемещает трос, св занный с ней через изол торы 6. При этом нож 1 опускаетс в губку 2, и цепь разъединител замыкаетс . При вращении лебедки в обратную сторону происходит отключение разъединител .When it is necessary to turn on or turn off the disconnector, the drive winch 5 is rotated and moves the cable connected to it through insulators 6. The knife 1 is lowered into the jaw 2 and the circuit of the disconnector is closed. When the winch is rotated in the opposite direction, the disconnector disconnects.

Claims

1. A high and ultra high voltage disconnector with a movable contact mounted on a suspension insulator, for example a wire, and moved by a cable, characterized in that, in order to create a disconnector without an insulator column, reducing the number of insulators , as well as increasing the reliability and reducing the cost of the disconnector, the latter is designed so that in it the knife and the sponge are attached directly to the wires of the transmission line or to the busbars of the switchgear.

2. A disconnector according to Claim 1, characterized in that, in order to eliminate the sag of the connecting wire between the sponge and its attachment point, the unit is attached to the wire or bus and insulators are located between the winch and the unit.

3. Disconnector according to claim 1, characterized in that the knife is made in the form of a load having the form of, for example, a cylinder, a dash, a cone or another streamlined shape, and the sponge of the disconnector is in the form of a hoop, a basket, a round mesh and There is a ratio of not less than 1: 8 between the failure of the knife and the sponge in the sponge between the linear and transverse dimensions.

4. A disconnector according to claim 1, characterized in that its knife is made in the form of a rod, moving progressively along the radius or otherwise before entering the sponge, which is a wire, pipe or rod, angled to the knife from 10 to 90 ° .

5. A disconnector according to Claim 1, characterized in that the sponge is mounted on a console, for example, a sickle-shaped form, a transmission line or tires fixed on the wire.
