Description

The invention relates to electrical engineering in the field of creation of liquid metal current-particle devices, for example, for unipolar electric machines.

A mercury current collector is known, containing-,; and, located on fixed electrodes,:. contact gap between which (, / kena mercury 1.

The disadvantage of the device is low reliability due to the possibility of isnarenine and mercury flow.

The closest to the technical essence of the invention is a centrifugal mercury current collector containing an external rotating, more common:) legograph, provided with a 1st radial nonreg (a zredka mn-loiatka.mi, and an internal f neutral electrode, in the contact gap between the electrodes is located mercury. Immobile the electrode is provided with partitions installed with a gap between the end surfaces of the stationary electrode. The exception in the mercury outflow device from the contact gap is provided by preventing the flow of ohm gas generated during movement of the blades of the rotating electrode 2.

The disadvantage of the device is its low reliability, due to the fact that when the electrode stops, the gas flow disappears and mercury evaporates freely. When starting the electrode, the gas flow does not arise m-notably, which does not exclude the possibility of mercury spilling out of the contact gap. The gas flow does not provide sufficient cooling of the electrodes when large currents flow through them.

The aim of the invention is to improve the operation of the device.

The unallocated goal is achieved by the fact that in a centrifugal mercury current collector containing an external rotating cup-shaped electrode equipped with radial partitions and an internal non-moving one electrode, in the contact gap between the electrodes there is a mercury, a free surface of mercury in the floor p, | and on the palpable electrode there is a node of water slots, while in the body it is stationary: I; h; e.:; the electrode is made of two channels for and; water recirculation, which have an outlet; The cavity lies on the 1cc electrode in the area in which it is located. water layer.

bia fig. 1 is a centrifugal 1) a tuberculosis toxoid, a hfodo.lny section; in fig. 2 - section A - A in FIG. I.

The current collector contains an external rotating frequently shaped electrode 1, equipped with radial non-campuses 2. Electrode I is mounted on shaft 3. Inside the electrode floor there is an internal fixed electrode 4. In the contact gap, mercury 5 is located between electrodes 1 and 4. Free surface of mercury 5 is in the cavity of the rotating electrode 1 is located under a layer of water 6. In the body of the non-movable electrode 4 there are two channels 7 and 8 for the circulation of water, which have an outlet with axial holes 9 to the bottom of the rotating electrode 1 in the zone and a layer of water 6. In the body of the non-moving electrode 4, also, at least one, through channel 10 for introducing mercury 5 into the contact gap is also made.

The device works as follows.

Before the current collector begins to work, through the through channel 10, mercury 5 is introduced into the contact gap, and channels 7 and 8 are filled with water, through which water falls into the electrode floor, to form a layer of water 6 above the mercury layer 5.

When the shaft 3 rotates with the rotating electrode 1, the mercury 5 under the action of the centrifugal force spreads over the inner cylindrical part of the often-shaped electrode 1, closing the electrodes 1 and 4 but all forming the surface of their contact parts. The electrical circuit I - 1 (Fig. 1) closes. Due to the same centrifugal force, water covers the free surface of mercury 5 with layer 6, whereby water circulates in channels 7 and 8 through openings 9.

Water plays a dual role: it is a shutter for mercury, preventing its evaporation, and cools both the mercury itself and the electrodes I and 4. When the shaft 3 stops, the mercury from the upper part of the cavity of electrode 1 flows down and disperses in the internal cavity of the cup-shaped electrode 1. Between the partitions 2. Water also flows down and fills the space above the free surface of mercury, isolating the mercury from the external atmosphere and excluding its evaporation.

The proposed device, by eliminating the loss of mercury and improving the cooling of the current collector, increases the reliability of the device.
