From the ninth Sichuan International Electric Power Industry Bo Jianhui news: Chengdu Electric Power Bureau retired old staff, senior technician Ren Yi invented "except for hot electrical contact fasteners" and "high current but hot electrical contacts “Fasteners†and “Special wrenches for shrinkable multi-function aerial work†were awarded patent certificates issued by three national intellectual property offices. In the eyes of ordinary people, a small bolt is not a "no" thing, but in the power system, there are many electrical connectors, and many of the joints are bolted, and the joints are overheated to cause hidden troubles or accidents. It is especially troublesome and helpless in the power system industry. In particular, many power maintenance workers know best: the joint overheating problem afflicts people, and the processing of joints is "not very big but the problem is very big." The problem of joint overheating has always been a serious problem that plagues the safe production, economic operation and reliable power supply of power systems. It is a "highly pathogenic" cause of power grid failure, and it has become a lingering part of the electrical manufacturing, installation industry and power supply enterprises. Heart disease. Including GBJ149-90 national standards as well as industry standards, power industry guidance books, substation maintenance manuals, and even including colleges and universities textbooks are consistent: the electrical connectors are overheated, long-term troubles for power generation, power supply, electricity, it is difficult to change the phenomenon! The world has also relied on experience and common sense to always determine that any joint that has a large current will inevitably heat up and overheat. These phenomena are "very normal" and cannot be changed. In the power system, if the joint is not too hot, it is considered abnormal.
Only the senior staff of the Chengdu Bureau of the high school education level was the worker of the Qingbaijiang Power Supply Bureau, which is 67 years old this year. Before retiring, since 1965, he has been a substation installer and a substation repairman. He has been dealing with electrical connectors for most of his life, and has an unforgettable experience of the damage caused by overheating of electrical connectors. Although he is as hard-working as many maintenance personnel, he has taken many technical measures to deal with overheating faults in electrical connectors. However, all technical measures only solve the surface problems and solve the fundamental problems.
In order to change this situation, Ren Yi spent most of his life researching technology. In 2001, he finally formed a unique solution in the hard work and applied for patents to the country. January 13, 2010, national knowledge The Property Office officially issued three patent certificates to Renyi technicians. On November 16, 2010, the State Intellectual Property Office officially accepted the “method of eliminating overheating of electrical contacts†in accordance with China’s participation in the international patent treaty, and the Renyi technician will become an internationally recognized craftsman.
On January 20 this year, the Science and Technology Department of Sichuan Province carried out the technical achievement appraisal of the patents invented by Ren Yi technicians. Experts commented: However, the special fasteners for thermal and electrical contacts effectively solved the long-term electrical contacts that plagued China's power system. The temperature is higher than the heating of the electrical contacts of the conductor, which is beneficial to reduce the line loss and avoid power system equipment accidents caused by overheating of the electrical contacts. The National Science and Technology Achievements Network also released the technical achievements of Renyi technicians on March 16 this year.
