SIGNALLING CURRENT-COLLECTING DEVICE Russian patent published in 2016 - IPC H01H29/02 H01R39/30 

FIELD: electricity.

SUBSTANCE: invention relates to rotary current-collecting devices, which uses liquid current-conducting media. Signalling current-collecting device comprises a housing, a shaft rotating on bearings, on which there is a rigidly fixed lower insulation bushing, on which there are rigidly fixed: a movable electrode made in the form of a metal ring, a movable part of the magnetic conductor, a movable ring-shaped permanent magnet generating magnetic field retaining arranged between teeth of the movable and the fixed magnetic conductors ferrofluid preventing leakage of the current-conducting fluid not interacting with the ferrofluid and located in a cavity produced by connection of two reservoirs located in the lower and the upper insulation bushings. Each of them is formed by the movable and the fixed electrodes, the moving and the stationary parts of the magnetic conductor and two insulating washers in the connection point of the reservoirs. Current-conducting fluid and ferrofluid are placed through a hole, which is twisted with a metal current-conducting pin encoded from the body with the insulation bushing with a nut tightening a terminal on the current-conducting pin from the wire laid and insulated inside the shaft transmitting a signal to another terminal, which is fixed with a screw isolated from the movable part of the magnetic conductor and the movable electrode by the insulating bushing passing through the movable part of the magnetic conductor and the movable electrode and the electrical contact with signal electrodes.

EFFECT: provided is current-conducting fluid level control and alarm in case of maximum permissible level of the current-conducting fluid at improved switchless transmission of electric energy of various power and other types of electric signals of any band.
