A pin 11 is installed in the holes of the frame 7 and 3. A half loop 12 and a pin

11 constitute a short closed loop 10. 3 sludge.

The invention relates to shipbuilding, in particular, to devices with simultaneous transfer of electric power and tractive effort of a ship to a podvany apparatus, and can be used in towed or probed underwater vehicles, especially when it is necessary to have one degree of freedom

The aim of the invention is to increase the reliability of the electrical connection, simplify the design and improve performance.

Figure 1 shows the device, a general view; figure 2 is the same, a longitudinal section; FIG. 3 is an electrical circuit diagram of the device.

The proposed device consists of a cable 1, a power seal 2, a sealed enclosure 3 located on the cable 1, a toroidal transformer 4 placed in the housing -3. The winding of the transformer 4 is connected to the cable 5 of the cable-cable 1. To increase reliability, each cable 5 on the cable-side 1 is sealed by an epiploon 6. On the side of the underwater vehicle, the device contains a sealed housing 7 with a toroidal transformer 8 placed in it, the terminals of which inside the underwater vehicle 9; The housing 3 is connected to the housing 7 by means of a collapsible short-closed coil 10, made of an electrically conductive material and consisting of a pin 11, passing through the central openings of both resistive transformers, half loops 12 enclosing the outer part of housings 3 and 7, and nuts 13 fixing the half loops 12. Cavities of housings 3 and 7, where toroidal transformers 4 and 8 are located, are filled with a sealing compound 14.

The device works as follows.

When the housings 3 and 7 are connected by means of a pin 11, a half loop 12 and nuts 13, both the mechanical and the electrical connection between the cable-cable 1 and the underwater cable are realized.

by the device 9. The power load senses the pin 11 and the housing 3 and 7. When an alternating electric signal is applied through the conductors of the cable 5 to the winding of the toroidal transformer 4, a magnetic flux occurs in the core of the transformer 4, exciting in the short-circuited coil 10 and the volumetric turn of water penetrating the axial holes enclosures 3 and 7, the current, which in turn excites the magnetic flux in the core of the transformer B, induces a voltage in its windings. If it is necessary to transmit constant electrical signals, they must first be converted into variables by known devices.

Estimate the efficiency of the proposed device by the formula

where X is the inductive resistance of one coil wound on a toroidal core; d is the active resistance of the parallel-connected volumetric loop of water and the shorted closed loop 10. For a core with parameters / and no. 100000, K40 25 25 11 and at an operating frequency of 20 kHz x 0.8 Ohm.

The appropriate choice of material and dimensions of the short-circuited coil resistance g can reach a value of 0.1-0.3 ohms. Substituting the values of Tg and x in the expression (1), we obtain 0.96 - 0.995.

Thus, the proposed device can significantly increase reliability, simplify the design and improve performance, virtually eliminate maintenance, while maintaining high efficiency.
