Abstract

The invention relates to electrical engineering, in particular to high-voltage, 6 switchgear equipment. The purpose of the invention is to improve serviceability, reduce metal consumption and simplify operation by eliminating the crosshead. The insulators 1, on which the fixed contacts 6 are fixed, and the movable insulators 2, on which the movable contacts 5 are fixed, are located at an acute angle, and accordingly the fixed insulators of the three phases and the movable insulators of the same phases are located at an angle of 90. 3 il.

Description

The invention is intended for switching devices in networks of overhead power lines with a voltage of 6-10 kV.

The purpose of the invention is to improve serviceability and reduce the size and metal consumption of a three-phase disconnector by installing it on a single-rack support without a traverse.

Fig, 1 shows a disconnector, a general view; in FIG. 2, a disconnector drive, look around; FIG. 3 is a circuit for connecting a disconnector at a line,

The stationary insulators 1 are located on the frame and are deployed in phases through 90, the axes of the movable insulators 2 are rotated relative to the axes of the stationary insulators at an acute angle. The frame of the disconnector is made of tire steel and is attached to the support by means of a clip in the holes 3, and the axes 4 of the movable insulators are each located in two holes of the gap. The movable knives 5 are bent relative to the fixed knives 6, the axes have levers 7 that are connected by tippers 8, equipped with adjustment screws, and connected by a pull 9 to the lever 10, the axis 11 of this lever is connected to the right by a pipe the calculation so that the pipe does not impede access to the support.

The actuator (Fig. O2) is made directly on the traverse 12, which secures the support by means of a clamp in the hole 13 from the opposite side of the disconnecting switch. The fixed disk 14 is attached to it at the same distance as the support 11 from the support. the disk is inserted axis 15 with fixed movable disk 16 and the lever 17, the connection of the axes

13 and 11 with a pipe made with the help of a pin. The disks 14 and 16 have holes located around the circumference. The on position is locked by the pin, and the off position by the padlock through the matching holes. The ram clamp 18 serves to attach a ground descent. one

When installing the disconnector on a simple support (FIG. 3), the wires of the line are broken on a single-post support 19, the insulators 20 plug the wires from us, and the insulators 21 connect the wires to us. The terminals 22 of the fixed knives of the disconnector are connected by cables to the wires running from us, the terminals 23 of the movable knives are connected by flexible cables to the wires leading to us. There are bogus insulators 24. The crossbars of the insulators 21 are turned around ogGory by 90 with the expectation that the insulators are sufficiently far from the drive tube.
