Shanghai Electric Machinery Factory Generator Model 1969

Introduction The generator model of Shanghai Electric Machinery Factory in 1969 was TQ-3-2. In 1969, Shanghai Electric Machinery Factory first designed and manufactured a 125,000 kilowatt water-cooled double steam turbine generator set.

Shanghai Electric Machinery Factory Generator Model 1969

Model TQ-3-2. In 1969, Shanghai Electric Machinery Factory first designed and manufactured a 125,000 kilowatt internally cooled double steam turbine generator set. The machine adopted the latest international double water cooling method at that time, applying it. thermal and other technologies are directly coupled and driven by the steam turbine, which has large overload capacity and fully complies with the requirements of international IEC standards. It has the characteristics of high short circuit ratio, good stability for power grid, small size, light weight, low material consumption, simple system and convenient operation and maintenance. Currently, this product has been developed into a train of 50,000 to 300,000 kilowatts, with an apparent power of 62,500 to 353,000 kilowatts, an active power of 50,0000 to 300,000 kilowatts, voltage from 10,500 to 18,000 volts, current from 3,440 to 11,320 amps. and rotation speed of 3000 rpm, power factor is 0.8-0.85, frequency is 50 Hz, efficiency is 98.1-98.45%, stator weight is 52 to 157 tons and the rotor weight is 18 to 57 tons. . It can be used for industrial and agricultural production as well as for lighting in large and medium-sized cities.

What is the qualification standard for hydraulic pressure testing of a water-cooled double generator?

On October 27, 1958, the first double generator 12,000 kilowatts at 3,000 rpm in the world. The water-cooled turbine generator was born in Shanghai Electric Machinery Factory.

In December of the same year, the Soviet Union organized a large-scale conference on turbogenerator cooling at the Leningrad “electricity” plant. In addition to the participation of prinmajor automobile manufacturers and research units of the Soviet Union, this meeting also included Wu Tianlin, deputy chief engineer of the Harbin Automobile Plant in Poland, Hungary and China, and Wang Geng of the Shanghai Automobile Plant . In accordance with the leaders' instructions, Wu Tianlin announced at the conference that China had produced a 12,000 kilowatt, 3,000 rpm double water-cooled turbine generator, which shocked the delegates present. Alexeiev, President of the Soviet Society of Electrical Engineering and Academician of Soviet Scientific Communications, congratulated the Chinese representatives and told the meeting that China was the first to test produce a twin-cooled turbine generator to water of 12,000 kW at 3,000 rpm using a 6,000 rpm motor. Rotary shaft kW. In Conference Proceedings and Proceedings. This is the first foreign report on the first testproduction in China of a double water-cooled turbine generator.

The test pressure is 1.5 times the working pressure of the pipeline system, but should not be less than 6 kg.

1. Block each water distribution point in the pressure test pipe section, slowly inject water and at the same time exhaust the air in the pipe.

2. Once the pipe is filled with water, carry out a leak check.

3. After pressurizing the system, the pressure should be increased slowly using a hand pump and the pressure increase time should not be less than 10 minutes.

4. After the pressure is increased to the specified test pressure, stop pressurizing, stabilize the pressure for 1 hour, and observe whether there is leakage at each interface.
