Description

one

This invention relates to radio engineering and can be used to channel aggregate.

Known Electromechanical waveguide switch containing a stator of a diamagnetic material with waveguide channels, a rotor with an intermediate waveguide channel and electromagnets, the windings of which are distributed coaxially with the waveguide channel-. E stator 13.

However, the electromechanical waveguide switch has a small isolation between channels, low stability while maintaining good matching, and high electrical strength in the connected channel.

The purpose of the invention is to increase the separation between the waveguide channels and increase its stability.

To do this, in an electromechanical waveguide switch containing a stator of diamagnetic material with waveguide channels, a rotor with an intermediate waveguide channel and electromagnets, the windings of which are placed coaxially with the waveguide channels of the stator, are made in the stator coaxially with each waveguide channel

annular grooves, each of which contains a ring of ferromagnetic material, covered with an electrically conductive magnetic lubricant, and

5 The rotor is made of diamagnetic material.

Fig. 1 shows the structure of an electromechanical waveguide switch; figure 2 - node I on

10 of FIG. 1 at an increased scale.

The electromechanical waveguide switch contains a stator 1, a rotor 2, rings 3, an electrically conductive magnetic lubricant 4, electromagnets 5, and also springs 6.

Electromechanical waveguide switch works as follows.

In the fixed position of the rotor

20 2 rings 3 are fully fitted to the surface of the rotor 2. In this case, the electrically conductive magnetic lubricant 4 fills completely the gap remaining between the rings 3 and the surface of the rotor 2, as well as the gap between the surface of the stator 1 (in the annular grooves) and the side surfaces rings 3, carveJM realizes a continuous and equal in magnitude electrical resistance

contact between the walls of the waveguide channels of the rotor 2 and the connected waveguide channels of the stator 1, as well as between the walls of the disconnected waveguide channel of the stator 1 and the lateral cylindrical surface of the rotor 2 Contact pressure is developed using a spring-b installed in the annular grooves of the stator 1 and abutting the rings 3. When the rotor 2 is rotated from one fixed position to another at the same time (or with a small advance), a voltage is applied to the windings of the electric device by a command from a switch control device (not shown). magnets 5 which, overcoming the resistance of spring used, the ring 3 is retracted deep into the grooves in the stator 1, their withdrawal from contact with the surface of the rotor 2. The electrically conductive magnetic lubricant 4 remains on the surface of the rings 3 without disruption Referring to the gap between the rotor 2 and the stator

1c waveguide channels. When the rotation is completed (the second fixed position is set), the electric current through the windings of electromagnets 5 stops at a given angle, and the rings 3 are pushed out by the springs 6 from the grooves of CiaTopa 1 until they stop against the surface of the rotor 2, thereby ensuring the connection of the walls of the waveguide channels of the rotor 2 and the stator 1 in a new position.

The use of the proposed electromechanical waveguide switch has several advantages over the use of the prototype. There are no extremely high requirements for manufacturing accuracy and quality of processing of the cavity of the stator 1 and the lateral surface of the rotor 2, as well as the accuracy of the installation of the rotor 2 in the stator 1, which greatly simplifies and reduces the cost of manufacturing waveguide switches. No electrically conductive magnetic lubricant 4 in the gap between the rotor

2 and stator 1 at the moment of switching

channels greatly reduces the amount of required torque, which must be developed on the rotor shaft 2 to rotate it, which allows the use of simple, compact and ma. destructive plunger electromagnetic drive instead of a powerful, cumbersome and complex electromechanical drive (using an electric motor, its power supply unit, a reducer). It also increases the reliability of the switch. The best technical characteristics allow replacing them with cascade switching of several switches, which is currently used as a single efficient measure to increase isolation between channels (for example, additionally turning on ferrite switches in each arm of a mechanical waveguide switch).
