Abstract

The invention relates to electrical engineering, in particular to cable technology. The purpose of the invention is to increase the service life of the cable by individually and more intensively cooling the cores. The tip consists of two parts 1 and 3. In one of them there is a hole 18 for connecting a water fitting and a groove; In the other part an insert 2 with holes 9 is placed for connecting a water choke. Box 2 has longitudinal 6 and 7 radial channels for the passage of water. With this design, water under pressure is supplied through two nozzles by two streams to the conductors of direct and reverse polarity, which ensures the same conditions of their intensive cooling even under the condition of their different electrical resistance along the length of the cable. 1 il. c (L 16 15 ° C ° o oo 4ib OO with

Description

The invention relates to electrical engineering and can be used in electric welding technology to connect a power transformer to a welding pendant.

The purpose of the invention is to increase the service life of the cable by individually and more intensively cooling the days of the veins.

The drawing shows the proposed tip, a general view.

The tip contains part 1 with an insert 2 and part 3 with a groove. Insert 2 is inserted into part 1. When assembled, the insert is inserted into the groove of part 3. In the insert there is an opening 4 for connecting and soldering the current-carrying core 5 of the same polarity. The insert is provided with a longitudinal 6 and 7 radial channels for the passage of water. Pro- Dolny channel 6 is plugged in the front part, open in the conde part 8 and connected to the hole 9 of part 1 by the radial channel 10. The surface of the insert 2 is insulated with a dielectric gasket 11 and a dielectric rigid sleeve 12. The sleeve 12 is fixed on the insert 2 by a threaded connection and forms a collar channel 13 around the cylindrical part of the insert for the passage of water. The sleeve is also suitable for connection to the insert of the dielectric sheath, which insulates the unlike wires of the cable. When assembling parts 1 and 3. of the tip between them, an insulating plate 14 of PCB and sealing cords 15 of rubber are installed. Parts of the tip are fastened together by a bolt 16. An insulating washer 17 is installed under the bolt. 18 and 9 slit holes. pressed for connection to the nozzle.

The tip of the work is as follows between them through a bolt sealant.

at once.

Providing an individual more intensive and uniform cooling, the price of the live and reverse polarity is as follows. .And under pressure of 2 and 3 atm, it is supplied to one of the tips of a two-pole cable and through two nozzles (not shown), screwed into holes 9 and 18, passes through two non-displacements.

with threads. The first stream enters the longitudinal channel 6, and then along three radial channels 7 - into the annular

the channel 13 formed by the cylindrical part of the insert 2 and the dielectric rigid sleeve 12. Then, washing the straight polarity veins, enclosed in a dielectric shell (not shown), the water is directed to another

the cable lug of the same design and further to the drain through the channel 10 and the hole 9 of the other tip. The second water stream flows around

inserts 2 and further falls into the cavity formed by the sleeve (not shown) of the cable and the outer surface of the dielectric envelope covering the straight polarity core (not shown). This stream, having cooled the conductors of reverse polarity, is directed to the other end of the cable. and gets to drain through the hole 18 of the other tip.

The use of the proposed tip, which provides an individual supply of water to l; direct and reverse polarity silts provides the same conditions for intensive

cooling of the wires even under the condition of different electrical resistances along the length of the cable, which increases the durability of the cable by 20-30%.
