RU2147362C1 - Method for transfer of tank generators to welding operations - Google Patents

Abstract

FIELD: repair of tank armament and equipment with employment of welding device. SUBSTANCE: generator excitation winding is manually disconnected by unscrewing the connector assembly from the driver's seat. The connector socket corresponding to the excitation winding gets connected to the wire running from the generator armature through an insulated wire, the other end of the generator armature is preliminarily disconnected from terminal "Я" of the generator regulator. The method allows to transfer generator of any tank within 4-5 minutes to welding operation directly from the driver's seat preventing any damage to supply line loads. EFFECT: higher efficiency. 2 dwg

Description

 The invention relates to the field of repair of armored vehicles and equipment (BHT).

 Up to 20% of repair work carried out in the field at the BHTF is electric welding and electric arc cutting. The main welding work carried out in the field: repair of armor, mudguards and wing flaps, preparation of vehicles for evacuation (cutting tracks, driving wheels, balancers).

 Existing mobile workshops based on ZIL-131 vehicles with welding generators (5 units) do not provide the entire scope of work in the field.

 The method of using the welding generator GD-304UZ at a tank repair workshop (see Tank repair workshop TRM-80. Technical description and operating instructions. - M .: Military Publishing House, 1984, pp. 65-66) is to provide a drive for a DC generator GD-304UZ from the vehicle’s power plant, the welding current is controlled by changing the resistance of the remote control rheostat in the forced field winding from the rectifier connected to the 220 V line network from the generator of the power plant. The welding generator is bulky, heavy and current-carrying (315 A) does not allow repairing armor protection and cutting most parts.

 There is also a method of electric welding from an onboard generator SG-10 (see Product 608. Operating Instructions. 608. IE-2, p. 121-123). The disadvantage of the prototype is the use of the relay unit ESA-1 to switch the generator into self-excitation mode and disconnect the wiring system from the generator. With faulty batteries or elements of the ESA-1 unit, welding does not work and it is impossible to switch the generator.

 The power supply system of modern tanks, including the generator and the relay-regulator, is not structurally adapted for welding, but this is possible in principle.

 The objective of the invention is to develop a method of switching tank generators without structural changes in the power supply system for welding.

 This problem is solved by disconnecting the SG-10 starter-generator in the generator mode from the consumers of the flight network and switching it to self-excitation mode by connecting the armature to the excitation winding (OB) with the engine running, since the engine is started by the SG-10 in the starter mode. The current strength is regulated by changing the speed of the diesel engine of the tank.

The invention is illustrated in FIG. 1 (circuit diagram), FIG. 2 (wiring diagram), where:
1 - starter-generator SG-10;
2 - relay-controller R-10TM;
3 - wire connecting the terminal of the YaG with the terminal "I" of the relay regulator;
4 - a wire connecting the OB (Fig. 1) of the generator (terminal Ш) with the P-10TM connector;
5 - plug connector R-10TM;
6 - socket N 3 connectors R-10TM;
7 - connecting wire;
8 - welding cable with holder.

 To switch the SG-10 tank generator for welding, it is necessary to start the diesel engine (SG-10 works in the starter mode), set the idling speed, on the R-10TM relay controller (2), unscrew the plug 5, it turns off the R-10TM differential-minimum relay and batteries with consumers are disconnected from the generator. The wire 3 is disconnected from the “I” terminal of the R-10TM and connected to the welding cable 8. In the socket N 3 (6) of the connector 5, a connecting wire 7 is inserted, which connects the generator OB through the wire 4 to the armature of the “YAG” generator (wire 3).

 The welding current strength of the SG-10 generator, connected in the self-excitation mode, is controlled by changing the rotational speed of the crankshaft of the drive motor.

 The method is simple, allows you to carry out all the switching from the place of the driver for 5-10 minutes. In addition to the existing tank equipment, a welding cable with a holder 8 and an insulated connecting wire 7 with a cross section of 3-5 mm will be required.

 The technical result of using the method of switching tank generators for welding is the ability to quickly perform welding and electric arc cutting (current up to 500 A) at the facility by the crew without the use of mobile workshops, which are inferior to the SG-10 generator in terms of chassis throughput and welding generator capabilities.
