Description

The invention relates to electrical engineering, in particular, to equipment for organizing high-frequency communications over wires of overhead power lines, and can be used in the construction of switchgear for power plants and superhigh voltage substations.

The purpose of the invention is to simplify the design and reduce the size.

FIG. 1 shows a device for separating high frequency signals; figure 2 - the same plan.

The device contains six capacitor bank 1 batteries located on the supporting elements 2 under the phase conductor of the power transmission line 3 in a group, the lower and upper plates of which are connected by metal frames 4 and 5 to create the necessary rigidity and electrical connection of the plates. The bottom metal frame 4 and through it the bottom plates of the capacitor banks are grounded. On the upper metal frame 5, two high-frequency barriers 6 are installed, the lower contacts of which are directly connected to the upper metal frame 5, and through it to the upper plates of the capacitor banks and the bus 7 among themselves. Thus, the structure of six capacitor banks 1, connected by metal frames 4 and 5, is simultaneously used as a carrier element. The attachment device 8 and one of the other two high-frequency barriers 9 are placed on separate supporting elements 2, and the second is mounted on the wires of insulators on the portal 10. The equipment has one descent 11 from the phase conductor of the power line.

The construction of the device begins with the implementation of the supporting elements 2 under the battery of capacitors 1, the high-frequency layer 9 and the connection device 8. On the prepared base of the six supporting elements 2, the lower metal frame 4 is installed, then six capacitor bank 1 batteries, and the upper metal frame 5 on them. On the latter are mounted dya high frequency barriers 6, then the attachment device 8 and the high frequency bar 9 are mounted on a separate standing support elements 2. Another high frequency5

The new barrier 9 is suspended on the portal 10. After all the equipment has been installed, the system is mounted.

The device is designed to reduce the mutual effects between high-frequency communication channels made via different air lines, is a T-shaped LC link and is switched on at the switchgear, where it is necessary to make a frequency separation between the O split lines. .

In a high-frequency separating filter device, capacitances C are formed by coupling capacitors, and inductances are formed by high-frequency barriers.

The bottom metal frame 4 makes the structure more durable and at the same time electrically connects the bottom plates of the capacitor bank batteries to each other and to the ground conductor. The upper metal frame 5 evenly distributes the static and bending (with the wind) load from two high-frequency barriers to the capacitor bank batteries, makes the structure strong and simultaneously electrically connects the top plates of the capacitor bank batteries between 5 each other.

The design of the high-frequency signal separation device makes it possible to significantly simplify its installation, reduce the size of the area occupied by the switchgear, reduce engineering utilities accordingly, reduce the number of supporting elements, as well as the number of slopes from the phase conductor of the transmission line.
