The world's first substation intelligent test system in the 500 kV Jiangsu Wujiang substation officially put into use on the 16th. It is understood that this system will make work more efficient than the traditional way to improve 3 to 4 times, work intensity reduced by 70%.
According to reports, electrical test is to improve equipment reliability, to ensure the safe operation of the power grid key technologies. In recent years, the electrical test from the traditional preventive tests continue toward the state maintenance, online monitoring direction, but the electrical test equipment there is still a low degree of integration, the single device defect, the test process requires constant equipment replacement , Wiring changes, the site work efficiency is low, great security risk. How to reduce the replacement of test equipment and wiring has become the bottleneck that restricts the development of electrical test.
In the face of this problem, Jiangsu Provincial Electric Power Research Institute under the professionals secretly provoked the determination to pay the heavy burden. In July 2012, Jiangsu Electric Power Research Institute organized core professional forces. After more than four months' extensive research and in-depth research, it finally developed the first international intelligent test system for on-site operation, which can effectively call data to ensure on-site Quick and safe operation. December 7, 2012, this intelligent test system for the first time in the EPRI 220 kV training base for trial use. In view of the problems and defects in trial, EPRI kept improving, after more than 150 days of serious exploration, improved and perfected. On May 16, the system was successfully put into use in Wujiang Substation of 500 kV.
It is reported that the substation intelligent test system consists of intelligent test vehicle transformer and intelligent test vehicle line spacing. ASTRI for the transformer, the characteristics of line spacing equipment, innovative research and development of a number of intelligent high-pressure test equipment, test system to achieve a one-time wiring, test circuit self-diagnosis, test procedures programmed operation, test results of intelligent analysis, to achieve high-pressure test The traditional mode of operation to intelligent, automated changes, work efficiency than the traditional way to improve 3 to 4 times, work intensity reduced by 70%.
Transformer intelligent test vehicle test wiring from the traditional 189 / time reduced to 24 / time; 500-kilovolt transformer test time from a half to a half shortened, the experimenter reduced from 8 to 4; line interval intelligent test car once The completion of testing and high-voltage testing of equipment such as three-phase circuit breakers and isolating switchgears has drastically reduced the number of test equipment and wiring, reduced the test time from 8 hours to 3 hours, and reduced the number of test persons from 6 to 3.
A heavy duty lathe can rotate a workpiece along its axis to perform operations such as grinding, cutting, and drilling like normal CNC lathes. But conventional CNC lathes are for ordinary purposes only, and heavy-duty lathes are designed with special turning spindles different from other machine tools.
In the center of the turning machines, there will be heavy loading saddles for the heavy machining driven by spindles. That center place is the center of gravity of the workpiece, so the turning spindle at the left side shall work with the tailstocks. Operators need to take care of not only the center of gravity but also the center part of the saddle units.
A heavy duty CNC Lathe isn't a stand-alone machine. Heavy-duty CNC lathes are a unique sort of CNC lathe. If you wish to get a very high superior lathe that will not need upgrading in the future, the heavy-duty lathe is surely a sound investment.
Heavy-duty turning lathes are machines made of high-quality materials compared to conventional machine tools and incorporate the most advanced technology. Various designs of heavy-duty CNC lathes involve their center height, bed width, maximum swing, spindle type, travel time, etc.
Heavy-duty CNC lathes are highly efficient machine tools, especially suitable for mass production due to their turning advantages inside the machines. Heavy-duty CNC lathes are ideal machines for metal processing and metal spinning applications in the workshop, as well as metal production work in repair shops, power plants, steel rolling mills, ship buildings, paper mills, and even textiles, oil, and mining industries.
