1935, Watsons electric appliance factory accepted an order from Hankou Zhouhengshun machinery factory to manufacture a three-phase alternator with 1 10 KVA, 375 rpm and 2300 volts, and Ding Shunnian was determined to be responsible for the design. After the production is completed, it runs well and the users are satisfied. Later, a larger three-phase AC engine was designed, with 500 KVA and 750 rpm. At the same time, he also presided over the design and manufacture of 15V, 1500A and 1440 rpm high-current DC generators, which solved the design and manufacture problems of high-current commutators.
1936, Watsons electric appliance factory accepted the task of ordering a 2000 KVA, 2300/6600 V three-phase power transformer from the Construction Committee, requiring delivery in three months. This is the largest transformer made in China at that time. Under the auspices of Ding Shunnian, the design and manufacturing tasks were completed as scheduled. When delivered, it was tested and accepted according to British standards, and all of them were qualified. In the task of designing and manufacturing two 33,000/2,300 volt step-down transformers in nanxiang town Substation, except for the high-voltage circuit breaker and high-voltage porcelain bushing imported from abroad, all the other equipment were designed by Ding Shunnian and developed by our technicians. After the substation is completed, it will be accepted by Shanghai Zhabei Power Plant, all of which are qualified and delivered safely.
Ding Shunnian did a lot of work on the product development and process improvement of "Watsons" brand electric fans during his work in Watsons Electric Appliance Factory. Due to the successful development of pressure cast aluminum for the squirrel cage rotor of electric fan, the patent certificate was obtained. Capacitance split-phase design is adopted to improve the design of electric fan, save raw materials and improve the performance of electric fan. At the same time, they successively developed "silent" desk fans, floor fans and ceiling fans with extremely low noise, perfected the series of electric fans, created the famous brand of Watsons electric fans, occupied almost all the domestic markets at that time, and began to export to Hong Kong, Macao and Southeast Asia.
1945 after War of Resistance against Japanese Aggression's victory, Ding Shunnian was employed as an engineer and head of the motor group in the Shanghai Manufacturing Plant of the Central Electric Appliance Factory of the Kuomintang Resources Committee. The factory began to manufacture transformers and asynchronous motors, and then gradually expanded. After the establishment of People's Republic of China (PRC), it developed into a famous Shanghai Electric Machine Factory in China.
From 65438 to 0947, Xia Dingshun was sent to Westinghouse Electric Company as an intern by the Resources Committee, and also studied in the Graduate School of the University of Pittsburgh. After returning to China from 65438 to 0948, he was sent to the new factory preparation office of Xiangtan Electric Machinery Factory and the new factory preparation office of Shanghai General Administration. At that time, Chu Yinghuang, the person in charge, attended the CPPCC meeting via Hong Kong, and Ding Shunnian was the agent responsible for organizing and leading Westinghouse interns to return to China. Later, according to the instructions of the China underground party conveyed by the Emperor Chu: First, protect the equipment and materials shipped from Westinghouse; Second, organize interns who come back from Westinghouse to inspect the production of private factories in Shanghai in the name of visiting. Ding Shunnian successfully completed the above tasks, safely transferred the technical data shipped from Westinghouse, and handed over the investigation materials to Yang Jinshan, party member, who was appointed to contact him.
1949 65438+ February. Shanghai Electric Machinery Factory was formally established, with Ding Shunnian as deputy director and chief engineer. During this period, he presided over the design, trial production and production of many new products to support the country's economic construction. For example, in 1950, DC motors for trolleybuses were manufactured and mass-produced; 195 1 year, a 4000 KVA, 22/6.6 KV three-phase power transformer was continuously wound with new technology. 1952 A 500 kV on-load voltage regulating transformer was manufactured by the new technology of vacuum drying and oil immersion.
With the rapid development of economic construction, the task of Shanghai Electric Machinery Factory is increasingly heavy, and the original factory building is no longer enough. After investigation, we decided to build a factory in Minhang Town, Shanghai. At that time, Ding Shunnian had been transferred to the Electrical Industry Administration of the East China Ministry of Industry as the director of the design department, but he still presided over the design of the new Minhang Electrical Appliance Factory.
1953, Ding Shunnian was appointed as the director of the second design branch.
1954 went to the Soviet union to participate in the review of Soviet aid to China 156 construction projects. After returning to China at the end of the year, he was transferred to the General Design Bureau of the First Ministry of Machinery Industry as the deputy chief engineer. 1956, the institute of technology and production organization of the First Ministry of Machinery Industry was established, serving as vice president and chief engineer. 1958 1 ding shunnian was transferred to the position of director of the electrical research institute of the first Ministry of machinery industry. With the efforts of the superior leaders, the institute has rapidly developed into an electrical research base with complete professional facilities, complete conditions and strong technical force. In terms of motors, the control micromotor, high-precision tachogenerator, various high-performance servo motors and complete sets of test equipment urgently needed by national defense industry and scientific research units, universities and factories have been developed and produced. In terms of electric drive and automation, the first set of magnetic amplifiers with small volume and high performance in China has been developed, which provides a supporting magnetic amplifier for the development of air-to-air missiles. In terms of electrical insulation materials, mica powder insulation materials, silicone insulation materials, F-class and B-class complete sets of insulation materials based on epoxy resin, polyurethane resin and polyester resin have been successfully developed and popularized. These materials were successfully developed in the late 1950s, which effectively ensured the improvement of the electrical performance and technical level of China's motors and electrical appliances and promoted the development of the electrical appliance industry. In terms of electrical alloy materials, the successfully developed Ag-Cd oxide contacts, Ag-Fe contacts and Al-Ni-Co permanent magnet materials have been in the leading position in China.
Semiconductor materials, from germanium and silicon purification, pulling single crystal to making various thyristor components, promote production. The thyristor developed in 1959 is only two years later than the first thyristor made in the world in the United States. The development of thyristor almost goes hand in hand with Japan. 1960, under the direct organization and guidance of Ding Shunnian, the first stand-alone computer station was built. At that time, the unified design of national transformers was calculated at this station. In electrical standardization, organize and manage the formulation and implementation of technical standards in the electrical industry and the work of China Committee of the International Electrotechnical Commission. Ding Shunnian served as the head or deputy head for many times and led a delegation to attend the IEC annual meeting.
